The comparative efficacy of percutaneous and surgical coronary revascularization in 2009: a review.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Medical, percutaneous, and surgical therapies for coronary atherosclerotic disease are developing rapidly, with many recent breakthroughs in metabolic control, improvements in catheter and stent engineering, and advances in surgical technique. Treatment guidelines are still in their infancy and do not take into account several of these recent innovations. Consequently, determining the most appropriate treatment for many patients remains challenging. In this review, we examine the most recent revascularization guidelines, discuss important new data and trials comparing contemporary stent technology and coronary artery b...

Reduced Intimal Hyperplasia in Rabbits via Medical Therapy after Carotid Venous Bypass.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Intimal hyperplasia is a major cause of restenosis after the interventional or surgical treatment of occlusive arterial disease. We investigated the effects of clopidogrel, calcium dobesilate, nebivolol, and atorvastatin on the development of intimal hyperplasia in rabbits after carotid venous bypass surgery. We divided 40 male New Zealand rabbits into 4 study groups and 1 control group. After occluding the carotid arteries of the rabbits, we constructed jugular venous grafts between the proximal and the distal segments of the occluded artery. Thereafter, group 1 (control) received no medication. We administered daily ...

Antibody-labeled liposomes for CT imaging of atherosclerotic plaques: in vitro investigation of an anti-ICAM antibody-labeled liposome containing iohexol for molecular imaging of atherosclerotic plaques via computed tomography.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We evaluated the specific binding of anti-intercellular adhesion molecule 1 (ICAM-1) conjugated liposomes (immunoliposomes, or ILs) to activated human coronary artery endothelial cells (HCAEC) with the purpose of designing a computed tomographic imaging agent for early detection of atherosclerotic plaques. Covalent attachment of anti-ICAM-1 monoclonal antibodies to pre-formed liposomes stabilized with polyethylene glycol yielded ILs, with a coupling efficiency of the ICAM-1 to the liposomes of 10% to 24%. The anti-ICAM-1-labeled ILs had an average diameter of 136 nm as determined by dynamic light-scattering and cryogen...

Benefits of catheter thrombectomy during carotid stenting: a preliminary study.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study evaluated the safety of using thrombus-extraction catheters in the setting of CA stenting.From August 2006 through June 2008, 43 symptomatic and asymptomatic patients with severe CA stenosis (>90%) underwent CA stenting with DEPs. After stenting and before removal of the DEP, an extraction catheter was passed through the stented segment. The extracted volume and the filtered extracted volume were visually examined for débris. The primary outcome was a composite of stroke and death at 30 days. Outcomes were compared with those in a control population of 783 patients who underwent CA stenting with a DEP, b...

64-slice multidetector computed tomographic evaluation of arterial conduit patency after off-pump coronary artery bypass grafting.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We set out to evaluate the accuracy of 64-slice multidetector row computed tomography (MDCT) in the evaluation of graft patency in 25 unselected patients who underwent off-pump revascularization with arterial conduits. A total of 73 coronary artery bypass grafts were examined by means of 64-slice MDCT. Postoperative clinical outcomes were also evaluated as indicators of early coronary bypass malfunction. Serial data from cardiac-specific biomarkers and from hemodynamic results were obtained in all patients. Two radiologists analyzed the MDCT images and reached consensus.No patients had evidence of postoperative acute m...

Pseudoaneurysm in the left ventricular outflow tract after prosthetic aortic valve implantation: evaluation upon multidetector-row computed tomography.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The high accuracy of multidetector-row computed tomography (MDCT) in evaluating prosthetic valve disorders has been confirmed. This, we believe, is the 1st report of the use of MDCT to detect and evaluate left ventricular outflow tract (LVOT) pseudoaneurysms in patients who have undergone aortic valve replacement with prosthetic valves. We used MDCT to scan 21 such patients, 3 of whom had a small pseudoaneurysm in the LVOT. Each pseudoaneurysm projected away from the LVOT and had a narrow neck that was located just below the sewing ring of the prosthetic aortic valve. One pseudoaneurysm was not thrombotic, 1 was partia...

Vladimir P. Demikhov (1916-1998) performed the world's first experimental intrathoracic transplantations and coronary artery bypass operation. His successes heralded the era of modern heart and lung transplantation and the surgical treatment of coronary artery disease. Even though he was one of the greatest experimental surgeons of the 20th century, his international isolation fueled speculation, suppositions, and myths. Ironically, his transplantation of a dog's head drew more publicity than did his pioneering thoracic surgical accomplishments, and he became an easy target for criticism. An account of Demikhov's life ...

Coronary artery fistula ligation in a child with use of the starfish heart positioner.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The Starfish Heart Positioner aids off-pump coronary artery surgery in adult patients by providing posterior cardiac exposure without incurring hemodynamic instability. Herein, we describe its use in a 17-month-old girl who had a right coronary artery fistula that drained to the right ventricle. Use of the device enabled exposure that afforded closure of the fistula without cardiopulmonary bypass. The patient was discharged from the hospital 2 days postoperatively. Six weeks later, she was well, and echocardiography showed no residual fistulous flow. PMID: 19876429 [PubMed - in process] (Source: Texas Heart Institute Journal)

Acute aortic dissection early after off-pump coronary surgery: true frequency underestimated?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Since the adoption of off-pump coronary artery bypass surgery (OPCAB), numerous investigators have compared its short- and long-term results with those of on-pump coronary bypass surgery. Some reports of OPCAB were quite favorable, whereas others were critical, claiming that it resulted in incomplete revascularization and reduced venous graft patency. A potentially serious complication of OPCAB, not heretofore sufficiently confronted, is the increased incidence of early postoperative acute aortic dissection, in comparison with the more familiar intraoperative and late-occurring aortic dissection after conventional on-p...

A 48-year-old man with a history of infective endocarditis and severe aortic regurgitation had undergone prosthetic aortic valve replacement at another institution. Two months later, the patient developed prosthetic valve endocarditis with an aortic root abscess and an aorto-left atrial periprosthetic valvular fistula through the detached posterior annulus of the mitral valve. We repaired the fistula by constructing a fibrous trigone made of bovine pericardium. We also replaced the prosthetic aortic valve with another prosthetic valve, while protecting the native mitral valve. PMID: 19876433 [PubMed - in process] (...

Sinus arrest during radiofrequency ablation of the atrioventricular-node slow pathway: implications and possible mechanisms.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Radiofrequency ablation has been associated with changes in autonomic function. In this case, a 52-year-old woman was referred for electrophysiologic study of recurrent supraventricular tachycardia. Typical slow/fast atrioventricular node re-entry tachycardia was induced and confirmed during the study. Radiofrequency ablation of the slow pathway of the atrioventricular node led to sinus arrest, which resolved once ablation was stopped. Given the distance of the ablation site from the sinus node, we inferred that mechanisms other than direct injury to the sinus node were involved. To our knowledge, this is only the 2nd ...

Minimally invasive aortic valve replacement: late conversion to full sternotomy doubles operative time.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In conclusion, the mini-aortic valve replacement is an excellent operation in selected patients, but its true advantages over conventional aortic valve replacement (other than a smaller scar) await evaluation by means of randomized clinical trial. The "extended mini-aortic valve replacement" operation, on the other hand, is a risky procedure that should be avoided by better preoperative evaluation of patients. In any event, the decision to extend a mini-sternotomy to a full sternotomy should be made early in the course of operation, before cardiopulmonary bypass is instituted.

Most medical literature regarding the anomalous origin of a coronary artery from the opposite sinus of Valsalva pertains to sudden death in the young. The surgical treatment of anomalous origin of the left main coronary artery from the right sinus of Valsalva is not particularly well codified, and when an anomalous left main coronary artery is associated with an extramural stenosis, treatment becomes more technically challenging.

Herein, we describe a technique that facilitates percutaneous vascular access when the traditional method of achieving access is unsuccessful. For multiple reasons, gaining access to small vessels in pediatric patients is sometimes difficult. In instances of atrial, ventricular, or great arterial communications, a wire can be positioned from a vein or artery across the communications into an artery or vein to which access needs to be gained. This wire then serves as a target for vascular access. All pediatric patients who underwent cardiac catheterization at Mattel Children's Hospital from July 2003 through June 2006, ...

New ring annuloplasty for extremely dilated tricuspid valve annulus: plication to physiologic septal segment size and over-reduction of posterior segment.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We describe a tricuspid valve ring annuloplasty for a 67-year-old woman who had an extremely dilated tricuspid valve annulus. During surgery, we found that the septal segment of the annulus was dilated to 60 mm, nearly double its normal size. Therefore, a standard annuloplasty without a prosthetic ring seemed unlikely to provide the needed annular plication. We used a 28-mm prosthetic ring, about the size of a normal septal segment, to plicate it. First, 5 U-shaped sutures, with 1 at each septal commissure, were used to plicate the septal segment to its physiologic size. Next, U-shaped sutures for the posterior and anterio...

Successful aneurysmectomy of a congenital apical left ventricular aneurysm.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Congenital apical left ventricular aneurysm is a rare clinical entity that is different from congenital left ventricular diverticulum. This aneurysm usually occurs as an isolated anomaly. Its clinical presentation varies, and it is usually diagnosed by exclusion. Herein, we report the case of a 54-year-old man who experienced progressively increasing symptoms of congestive cardiac failure. Through the use of contrast echocardiography and angiocardiography, and upon histopathologic examination, he was diagnosed to have a congenital apical left ventricular aneurysm. He was successfully treated by means of left ventricula...

Clostridium septicum aortitis causing aortic dissection in a 22-year-old man.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Clostridium septicum infection is a rare cause of aortic dissection, and the mortality rate for the condition is high. Only 26 cases of C. septicum aortitis have been reported; all of those patients were elderly, and 20 of them had an associated colonic neoplasm. Herein, we present the case of a 22-year-old man whose C. septicum aortitis resulted in aortic dissection that involved the entire length of the aorta. Upon autopsy, no neoplasm or other predisposing condition was identified in this patient. To the best of our knowledge, this is the 1st report of C. septicum aortitis, fatal or otherwise, in a young individual....

Extracorporeal membrane oxygenation using the TandemHeart System's catheters.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We describe the initial--and successful--use of the TandemHeart System's catheters to provide extracorporeal membrane oxygenation (ECMO), in 2 patients. In 1 patient, who was experiencing severe primary respiratory failure, the catheters provided a standard venovenous ECMO circuit. In the other patient, who had severe, acute pulmonary hypertension and right-heart failure, the catheters enabled a novel right atrial-to-left atrial circuit for ECMO. We discuss the potential of the TandemHeart System's catheters to provide novel and possibly superior vascular routes for the delivery of ECMO in different types of cardiopulmonar...
