Preclinical evaluation of a new self-expanding device for closure of muscular ventricular septal defects in a pig modelEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
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 i...

Acute compartment syndrome of the forearm that occurred after transradial intervention and was not caused by bleeding or hematoma formationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
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 co...

Microvascular obstruction after percutaneous coronary interventionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
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 antipl...

Coarctation of the aorta treated with the Advanta V12 large diameter stent: Acute resultsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Objectives: To report on the early results of treatment of coarctation of the aorta by dilation with a new polytetrafluoroethylene covered stent. Background: Transcatheter dilation of aortic coarctation carries the risk of aneurysm or rupture. Covered stent implantation reduces this risk but requires a large delivery system. The Advanta V12 LD covered stent is premounted and requires a 9-11 Fr delivery system. Methods: Covered stents on balloons of a diameter sufficient to anchor the stent in the coarctation were implanted using the smallest available delivery system. Secondary dilation with larger diameter balloons was pe...

We report a complication related to advancement of a large diameter long sheath in the obturator vein. In an adult with a previously thrombosed femoral vein, the obturator vein was inadvertently cannulated. During percutaneous pulmonary valve implantation, the Ensemble® delivery system could not be advanced after repositioning attempt. The obturator vein had been perforated and sheath was coiled up in the pelvis leading to a retroperitoneal pelvic hematoma. Continuity of the vein was established using two self-expanding covered stents. The obturator vein runs dorsally and joins the inferior caval vein at a very acute angl...

Hemodynamic and intravascular ultrasound assessment of myocardial bridging: Fractional flow reserve paradox with dobutamine versus adenosineEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Compared to coronary angiography, both intravascular ultrasound (IVUS) and CT-angiography provide important information with respect to the morphological aspects of myocardial bridging (MB). However, these modalities are limited in defining the hemodynamic and clinical significance of MB. Intracoronary Doppler studies demonstrate a peculiar abnormal Doppler flow profile associated with MB. Fractional flow reserve (FFR) after adenosine infusion has been used to assess the hemodynamic significance of MB, but FFR after adenosine induced hyperemia underestimates the significance of MB. On the other hand, high-dose dobutamine b...

Critical coronary stenoses have been shown to contribute to only a minority of acute coronary syndromes (ACS) and sudden cardiac death. Autopsy studies have identified a subgroup of high-risk patients with disrupted vulnerable plaque and modest stenosis. Consequently, a clinical need exists to develop methods to identify these plaques prospectively before disruption and clinical expression of disease. Recent advances in invasive and noninvasive imaging techniques have shown the potential to identify these high-risk plaques. The anatomical characteristics of the vulnerable plaque such as thin cap fibroatheroma and lipid poo...

Transradial simultaneous kissing stenting (SKS) with SheathLess accessEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Transradial coronary intervention is usually performed via a 5 or 6 Fr sheath due to the small calibre of radial arteries. Simultaneous kissing stenting (SKS) technique requires a guiding catheter 7 Fr or larger and is therefore difficult to perform via transradial approach. Conversion to femoral approach or additional arterial access is usually required to achieve this goal. To overcome this limitation, a hydrophilic 7.5 Fr SheathLess guiding catheter can be exploited. This catheter possesses approximately the same size outer diameter as a 6 Fr sheath and an internal diameter of a 7.5 Fr catheter. A smooth and successful ...

Influence of obstructive sleep apnea and treatment with continuous positive airway pressure on fractional flow reserve measurements for coronary lesion assessmentEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Obstructive sleep apnea (OSA) and sleep-disordered breathing have been implicated in the progression of cardiovascular disease and with increased risk of coronary artery disease, congestive heart failure, and stroke. Fractional flow reserve (FFR) is used to evaluate the physiological significance of coronary artery stenosis, and this technique is largely thought to be independent of systemic hemodynamic changes. Herein, we describe a case of OSA and sleep-disordered breathing cyclically altering FFR measurements from normal to abnormal in a patient with coronary artery disease. More specifically, we show that the abnormal ...

Real case virtual reality training prior to carotid artery stentingEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: A case rehearsal prior to an intervention may be useful in the planning and execution of carotid artery stenting. The use of patient specific simulation helps with planning of procedure and device selection, and may lead to use of less contrast and radiation, and shorter procedure duration. These may benefit the patient with increased success and lower complication rates. © 2009 Wiley-Liss, Inc. (Source: Catheterization and Cardiovascular Interventions)

Clinical safety and efficacy of a novel thin-strut cobalt-chromium coronary stent system: Results of the real world Coroflex Blue RegistryEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: This registry demonstrates the safety and efficacy of the Coroflex Blue cobalt-chromium stent platform in real-world practice. In the era of drug-eluting stents (DES), these results raise the serious question if the use of DES for primary prevention of restenosis and TLR is really justified.

Percutaneous versus surgical delivery of autologous myoblasts after chronic myocardial infarction: An in vivo cardiovascular magnetic resonance studyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Comprehensive in vivo CMR reveals reversed remodeling and improved systolic function, perfusion, and scar characteristics after AM transplantation. A relative increase in the arrhythmogenic peri-infarct border zone may explain previously reported arrhythmia. Percutaneous and surgical transplantation of AM both lead to comparable improvements in chronic MI. © 2009 Wiley-Liss, Inc. (Source: Catheterization and Cardiovascular Interventions)

Virtual angioscopy assessment for acute type B aortic dissection endovascular repairEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Discussion: Aortic dissection endovascular repair requires an accurate evaluation based on M-CT or magnetic resonance angiography (MRA). VA is a CT-based 3D reconstruction that provides a sort of information comparable to intravascular ultrasound (IVUS) that can be very helpful when it is not available and has many other potential applications in vascular surgery. © 2009 Wiley-Liss, Inc.
