Carotid artery stenting in high surgical risk patients using the FiberNet® embolic protection system: The EPIC trial results

Catheterization and Cardiovascular Interventions — Thu, 04 Mar 2010 00:00:00 +0100

Conclusions: The FiberNet EPS, used with commercially available stents, produced low stroke rates following CAS in high surgical risk patients presenting with carotid artery disease. The unique filter design including aspiration during retrieval may have contributed to the low 30-day stroke rate reported during CAS in patients considered at high risk for complications following carotid endarterectomy (CEA). © 2009 Wiley-Liss, Inc.

A novel concept in endovascular stenting for the treatment of old severely degenerated saphenous vein graft in the urgent setting

Catheterization and Cardiovascular Interventions — Wed, 20 Jan 2010 00:00:00 +0100

We report a critically ill-patient admitted for NSTEMI with acute pulmonary congestion, showing at urgent cardiac catheterization a severely diseased saphenous vein graft as the culprit vessel, with huge atherothrombotic burden. The graft was successfully revascularized by the implantation of 4 M-Guard stent (for proximal to distal) creating a full metal jacket. The M-Guard technology consists on a stainless steel platform wrapped by a micron-level polymer net, that seamlessly expands when the stent is deployed, providing protection from embolic showers. © 2010 Wiley-Liss, Inc.

Carotid stenting and bivalirudin with and without vascular closure: 3-year analysis of procedural outcomes

Catheterization and Cardiovascular Interventions — Wed, 20 Jan 2010 00:00:00 +0100

Conclusions: This was a negative study, with no significant difference on prolonged hypotensive events in patients with vascular closure device and bivalirudin, compared with those with manual compression and bivalirudin. Vascular closure devices were safe and effective with a low incidence of complications. In carotid artery stenting, bivalirudin is safe with low incidence of major bleeding and acceptable 30-day adverse event rates (stroke and death). © 2010 Wiley-Liss, Inc.

Transcatheter aortic valve implantation by left subclavian access in the presence of a patent LIMA to LAD graft

Catheterization and Cardiovascular Interventions — Tue, 22 Dec 2009 00:00:00 +0100

We present a case of successful implantation of the Corevalve aortic bioprosthesis via the left subclavian artery in a patient with a patent internal mammary graft to the left anterior descending artery. This unusual choice of access, in the presence of adequate caliber femoral arteries, was justified by the presence of mobile thrombi in the abdominal aorta. The risk of thrombus dislodgement and subsequent major cholesterol embolization was deemed higher than the risk of coronary ischemia due to the large caliber sheath required for transcatheter aortic valve implantation. This case shows that presence of a LIMA to LAD graft is not an absolute contraindication for homolateral subclavian access and that the procedure is feasible and relatively safe provided that certain rules are followed. ...

Drug-eluting stent fracture: Incidence, contributing factors, and clinical implications

Catheterization and Cardiovascular Interventions — Sat, 19 Dec 2009 00:00:00 +0100

Stent fracture has been observed in noncoronary vessels, especially in the superficial femoral and popliteal arteries and with bare metal stents in saphenous vein grafts of coronary arteries. Since the introduction of drug-eluting stents, stent fractures have also been reported in small studies and case reports. We reviewed these publications to assess what is known regarding the incidence, contributing factors, and clinical implications of drug-eluting stent fracture in coronary arteries. The reported rate of drug-eluting stent fracture in coronary arteries ranges from 1 to 8%, although much of the available literature is derived from single-center studies that are heterogeneous in their study methods. A higher risk of stent fracture may be associated with the right coronary artery locati...

Brain salvage for cardiac cerebral embolism following myocardial infarction

Catheterization and Cardiovascular Interventions — Fri, 18 Dec 2009 00:00:00 +0100

Acute ischemic stroke due to thromboembolism from the left ventricle is a serious complication following myocardial infarction (MI). Despite the attention given to acute stroke intervention, peri-MI ischemic stroke is an underappreciated condition. Here, we describe a case of acute cardiac thromboembolic occlusion of the middle cerebral artery with preceding MI in which brain salvage was achieved by balloon angioplasty. © 2009 Wiley-Liss, Inc.

Conclusions: Both conventional and cutting balloon angioplasty were effective at decreasing gradient and increasing lumen size acutely in patients with congenital and postoperative PVS, but reintervention was common with both treatments. Both methods of angioplasty provided limited benefit, and neither was curative for this complex disease. © 2009 Wiley-Liss, Inc. (Source: Catheterization and Cardiovascular Interventions)

Coil occlusion of a subclavian mycotic aneurysm

Catheterization and Cardiovascular Interventions — Thu, 17 Dec 2009 00:00:00 +0100

We report the first successful application of nonferromagnetic embolization coils for endovascular exclusion of a mycotic right subclavian artery aneurysm. A 58-year-old woman presented with acute cervical pain and a pulsatile mass in the right supraclavicular fossa under antibiotic medication for subacute infectious endocarditis. Diagnostic work-up including duplex sonography, digital subtraction angiography, and magnetic resonance imaging demonstrated a saccular aneurysm of the extrathoracic right subclavian artery. As an alternative to open surgery or stent-graft repair, this pathology was electively treated by transcatheter coil embolization. No neurological deficit or ischemic symptoms were noted during 9 months clinical follow-up. Multislice computed tomography scan revealed complete...

Is the left anterior descending artery really absent? - A decisive input from coronary CT angiography

Catheterization and Cardiovascular Interventions — Thu, 17 Dec 2009 00:00:00 +0100

This case report emphasizes the importance of coronary CT angiography (CTA) as a backup imaging modality in patients with suspected coronary anomalies and difficult canulation, during invasive coronary angiography by catheterization (Cath). In this patient, the numerous canulation attempts during Cath failed to identify a left anterior descending artery (LAD) leading to the diagnosis of absent LAD. CTA was done for further clarification, which easily visualized LAD originating from a separate ostium at the left sinus of Valsalva finalizing the diagnosis as absent left main artery with dual left coronary ostia. © 2009 Wiley-Liss, Inc.

Novel application of the "CART" technique for endovascular treatment of external iliac artery occlusions

Catheterization and Cardiovascular Interventions — Thu, 17 Dec 2009 00:00:00 +0100

We report the novel application of the Controlled Antegrade and Retrograde subintimal Tracking technique for the endovascular treatment of occlusions of the external iliac artery (EIA). We hypothesized that this technique would limit the extent of subintimal dissection to the length of the EIA occlusion, thus preserving patency of the internal iliac artery proximally and the circumflex iliac artery distally and minimizing the length of stent required to treat the occlusion, including the length of stent placed in the common femoral artery. The technical execution and clinical experience with this technique is reported. © 2009 Wiley-Liss, Inc. (Source: Catheterization and Cardiovascular Interventions)

Retrieval of an embolized amplatzer septal occluder

Catheterization and Cardiovascular Interventions — Tue, 24 Nov 2009 00:00:00 +0100

Percutaneous closure of secundum atrial septal defect (ASD) by various devices has been proven to be an effective and safe treatment modality for patients with congenital heart diseases. However, we have to be aware of the potential early and late complications like device embolization and formulate plan for rescue procedures. We have reported a case of successful closure of a large secundum ASD in a 23-year-old woman by a 40 mm Amplatzer septal occluder (ASO), which embolized into the right ventricle 4 hr after the procedure. This had caused palpitation and nonsustained ventricular tachycardia. Patient safety was our most important concern and after discussion with the cardiac surgeons and the patient, we would like to make a percutaneous stepwise attempt for retrieval.

We report two patients who developed atrioventricular (AV) block within 48 hr after uncomplicated device closure of ASD using the Amplatzer septal occluder (ASO) device. Despite trials of high dose steroids and non-steroidal anti-inflammatory agents in both patients, the response was inadequate and by the end of the first week, both patients were ultimately sent for surgical removal of their devices with complete resolution of their atrioventricular conduction abnormalities. We discuss the possible etiology and risk factors of AV block and propose recommendations for management of such a complication. © 2009 Wiley-Liss, Inc.

Adverse event rates in congenital cardiac catheterization - A multi-center experience

Catheterization and Cardiovascular Interventions — Tue, 03 Nov 2009 00:00:00 +0100

Objectives: To describe case mix variation among institutions, and report adverse event rates in congenital cardiac catheterization by case type. Background: Reported adverse event rates for patients with congenital heart disease undergoing cardiac catheterization vary considerably, due to non-comparable standards of data inclusion, and highly variable case mix. Methods: The Congenital Cardiac Catheterization Outcomes Project (C3PO) has been capturing case characteristics and adverse events (AE) for all cardiac catheterizations performed at six pediatric institutions. Validity and completeness of data were independently audited. Results: Between 2/1/07 and 4/30/08, 3855 cases (670 biopsy, 1037 diagnostic, and 2148 interventional) were recorded, median number of cases per site 480 (308 to 1...

Preclinical evaluation of a new self-expanding device for closure of muscular ventricular septal defects in a pig model

Catheterization and Cardiovascular Interventions — Sat, 31 Oct 2009 00:00:00 +0100

Aim of our study was the preclinical evaluation of a new self expanding device for interventional closure of muscular ventricular septal defects (mVSDs) in an acute pig model.Devices currently in use for closure of mVSDs still have their limitations. The deployment of the disks is dependent from the expansion of the stent, which can be associated with problems for sufficient closure of the mVSDs. This was the reason for developing a modified device with only one diskThe device was constructed in a single wire technique with a unique configured retention disk. mVSDs were created in six pigs with a specially designed punch instrument, and subsequently closed with our new device during the same session using a jugular or femoral vein approach. Potential residual shunting volumes were estimate...

Clinical features and outcomes of carotid artery stenting by clinical expert consensus criteria: A report from the CARE registry

Catheterization and Cardiovascular Interventions — Tue, 27 Oct 2009 00:00:00 +0100

Conclusions: Most CAS procedures submitted to CARE conformed to CECD recommendations for patient selection. For reported data, clinical outcomes at 30 days were similar for procedures meeting and those not meeting recommendations, and were similar to outcomes reported by other large registries. These findings suggest that acceptable patient selection criteria for CAS are employed as it expands beyond investigators into more widespread clinical practice. © 2009 Wiley-Liss, Inc.

Treatment for LMCA ostial stenosis using a bifurcation technique with a retrograde approach

Catheterization and Cardiovascular Interventions — Tue, 27 Oct 2009 00:00:00 +0100

A 69-year-old man who underwent coronary artery bypass surgery in February 2008. The surgery included grafting of the left internal thoracic artery (LITA) to the diagonal branch (D1) and a saphenous vein graft (SVG) to the left circumflex artery (LCX) due to ostial stenosis of the left main coronary artery (LMCA). The patient presented with recurring effort chest pain 18 months later. Coronary CT revealed that the LITA-D1 graft was patent, the SVG-LCX graft was occluded, and there was severe ostial stenosis of the LMCA. Coronary angiography was performed in August 2009, but a 5-Fr diagnostic catheter could not be engaged due to the severe ostial stenosis. Percutaneous coronary intervention (PCI) was performed 5 days later with an attempt to cross the lesion with a guidewire using a retrogr...

Safety and efficacy of carotid stenting in the very elderly

Catheterization and Cardiovascular Interventions — Tue, 27 Oct 2009 00:00:00 +0100

Conclusions: This large series of CAS with independent neurologic assessment is convincing evidence that the very elderly ([ge]80 years) can safely undergo CAS with stroke and death rates comparable to younger patients. The key to obtaining these excellent results is that CAS be performed by high volume, experienced operators who exercise restraint regarding patient selection. © 2009 Wiley-Liss, Inc.

The utility of trans-catheter aortic valve replacement after commercialization: Does the European experience provide a glimpse into the future use of this technology in the United States?

Catheterization and Cardiovascular Interventions — Tue, 27 Oct 2009 00:00:00 +0100

This article summarizes the evidence-base from recent clinical trials. The early results of these landmark studies suggest that transcatheter aortic valve implantation with either one of the prosthesis is feasible, safe, improves hemodynamics and, therefore, might be an alternative to conventional aortic valve replacement in very high-risk patients. However, all of the available transcatheter heart valves have certain disadvantages, limiting their use in daily clinical practice. The process of decision making, which valve to use and which access route to choose is illustrated in this article through clinical case scenarios. Additionally, the lessons learned thus far from the European perspective and the potential impact on the future use in the US are discussed. Despite of the progress in ...

Scanning electron microscopic analysis of different drug eluting stents after failed implantation: From nearly undamaged to major damaged polymers

Catheterization and Cardiovascular Interventions — Tue, 27 Oct 2009 00:00:00 +0100

Conclusion: Placement of drug eluting stents in tortuous vessels and/or calcified lesions could cause major surface damage by scratching and scraping of the polymer or drug by the arterial wall, even before implantation. There were remarkable differences among the stents examined, only minor damage with the Cypher, Taxus Costar, Janus, and Xience V, whereas the Endeavor, the Yukon, and the Janus DES showed large areas of surface injury. © 2009 Wiley-Liss, Inc.

Impact of abciximab on mortality and reinfarction in patients with acute ST-segment elevation myocardial infarction treated with primary stenting

Catheterization and Cardiovascular Interventions — Tue, 27 Oct 2009 00:00:00 +0100

Conclusion: Routine use of abciximab in patients with STEMI treated with primary stenting may reduce short-term rates of death or reinfarction in patients not administered preprocedural thienopyridine therapy, but does not appear to be beneficial in those who receive preprocedural thienopyridines. © 2009 Wiley-Liss, Inc.

Acute compartment syndrome of the forearm that occurred after transradial intervention and was not caused by bleeding or hematoma formation

Catheterization and Cardiovascular Interventions — Fri, 09 Oct 2009 23:00:00 +0100

Recently, transradial angiography and intervention have been performed with high success rates and low rates of vascular complications. The incidence of compartment syndrome after the transradial approach seems to be very low. However, bleeding in the arm can occur and may lead to the devastating complication of compartment syndrome of the forearm, which if not treated early, can evolve into a disability of the arm. In fact, most cases of such complications are caused by guidewire- or catheter-induced damage to small arterial branches that are considerably proximal to the puncture site. However, we encountered a case of compartment syndrome that was not caused by bleeding or hematoma formation and required urgent fasciotomy for its treatment. The forearm wounds were left open to allow the ...

Open Sesame Technique for chronic total occlusion

Catheterization and Cardiovascular Interventions — Fri, 09 Oct 2009 00:00:00 +0100

Angioplasty for chronic total occlusion (CTO) of the coronary artery is still technically challenging. New techniques to improve the success rate are still required. The inability to penetrate guidewires into the CTO lesion through the proximal cap is one of the most difficult situations. When any guidewire cannot penetrate into the CTO lesion, and if the lesion has both a hard proximal cap and a side branch ramifying at the proximal end of the lesion, the insertion of stiff guidewires and/or balloon inflation in the side branch may induce a geometrical shift of the hard plaque. This in turn enables the entry of a guidewire into the CTO lesion. This procedure has been termed the "Open Sesame Technique." © 2009 Wiley-Liss, Inc.

Clinical cerebrovascular anatomy

Catheterization and Cardiovascular Interventions — Fri, 09 Oct 2009 00:00:00 +0100

Stroke is often the result of carotid atheroma, which may cause ischemia via progressive arterial narrowing or lead to superimposed thrombus formation and subsequent atheroembolism to the intracerebral vasculature. Revascularization through carotid endarterectomy or carotid artery stenting with embolic protection devices has produced favorable results in appropriately selected patients. In planning the percutaneous approach, an arch aortogram is first acquired to determine arch type and identify the presence of any anatomic variants which may affect the approach to the procedure and catheter selection. Subsequent imaging of the cerebral vasculature is performed to delineate the collateral circulation that is present, including an evaluation of the Circle of Willis. Although Doppler ultraso...

Left main intervention in myocardial infarction

Catheterization and Cardiovascular Interventions — Fri, 09 Oct 2009 00:00:00 +0100

We report an 84-year-old patient who suddenly developed nausea, vomiting, hypotension, and needed intubation, assisted ventilation and pharmacological vasopressor support. Admission EKG showed anterior and lateral leads ST segment depression and 2 mm ST segment elevation in avR lead. Angiogram showed unprotected left-main coronary-artery (LM) sub-occlusive disease and totally occluded ostial right-coronary-artery (RCA), distally filled through the left-coronary system. Unprotected LM disease was immediately treated with bare metal stent. The stent jailed the left-circunflex coronary-artery (LCx) ostium but did not compromise the arterial flow. Lately, the patient was discharged in a very good health condition. Ten months angiographic follow-up showed an extremely compromised LCx ostium tre...

Coronary intervention with 4-French catheters

Catheterization and Cardiovascular Interventions — Fri, 09 Oct 2009 00:00:00 +0100

Conclusions: The performance of 4-Fr PCI requires a certain learning curve, following which a reduction in fluoroscopy time and use of contrast dye may be achieved. This improvement in procedural parameters and the low incidence of access site-related complications might allow 4-Fr PCI to serve as a minimally invasive approach for the treatment of coronary artery diseases. © 2009 Wiley-Liss, Inc.

The impact of hematocrit drop on long-term survival after cardiac catheterization: Insights from the Dartmouth Dynamic Registry

Catheterization and Cardiovascular Interventions — Tue, 06 Oct 2009 00:00:00 +0100

Conclusions: Periprocedural bleeding, defined by hematocrit drop, is associated with increased near-term and long-term mortality in patients undergoing diagnostic and therapeutic cardiac catheterization procedures. Long-term mortality is largely driven by up front 30-day mortality. Hematocrit drop was not an independent predictor for near-term mortality. Transfusion and low baseline hematocrit were independent predictors for near and long-term mortality. © 2009 Wiley-Liss, Inc. (Source: Catheterization and Cardiovascular Interventions)

Endovascular therapy for a ruptured popliteal aneurysm

Catheterization and Cardiovascular Interventions — Tue, 06 Oct 2009 00:00:00 +0100

Discussion: Up to 50% of PAA present with acute limb ischaemia is due to thrombosis or distal embolization. Rupture is an uncommon complication affecting less than 3% of PAA. Diameter greater than 2 cm or mural thrombosis are indications for elective intervention. Open surgical repair is the first treatment option. In selected patients, endovascular repair can be performed. Midterm results of this technique, recently reported, are comparable to open repair.© 2009 Wiley-Liss, Inc.

Microvascular obstruction after percutaneous coronary intervention

Catheterization and Cardiovascular Interventions — Mon, 28 Sep 2009 23:00:00 +0100

Successful revascularization of the epicardial coronary artery can be achieved in over 90% of percutaneous coronary intervention (PCI) procedures. However, postprocedural microvascular obstruction, despite the presence of normal epicardial flow, remains an important limitation which substantially reduces the beneficial effects of PCI. In this review article, a number of different methods available to diagnose microvascular obstruction after PCI are outlined. We also discussed the various pharmacological and mechanical strategies to reduce the occurrence of microvascular obstruction. In this regard, pretreatment with antiplatelet therapy remains crucial. In urgent PCI for acute myocardial infarction, available data suggest that manual thrombus aspiration device is beneficial in reducing the...
