CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Left-Ventricular Outflow Tract Ventricular-Tachycardia Event Following CoreValve Transcatheter Aortic-Valve Implantation

Danny Dvir, MD, Moti Haim, MD, and Ran Kornowski, MD

We describe a patient with severe aortic stenosis who underwent CoreValve (Medtronic) implantation and presented several days later with a tachyarrhythmic episode. The electrocardiographic features of the arrhythmia were compatible with left-ventricular outflow tract ventricular-tachycardia. The life-threatening event was not associated with ischemia or an electrolyte disorder and was not drug-induced. A probable cause was the irritation of the myocardium by the prosthetic valve. Clinicians should be aware that the presence of anatomical parameters that increases the risk for myocardial injury and the need for pacemaker implantation might indicate an increased risk of a tachyarrhythmic episode.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Successful Treatment for Refractory Coronary Thrombus with Scoring Balloon Angioplasty

Yusuke Hosokawa, MD, Keiji Tanaka, MD, and Kyoichi Mizuno, MD, FACC, FAHA, FSCAI

A female with chronic atrial fibrillation presented with an acute myocardial infarction. The angiogram revealed total occlusion of the right coronary artery. A combined strategy using intracoronary thrombolysis, aspiration catheter, plain old balloon angioplasty, and ‘‘Fogarty-like’’ procedure was performed. However, we failed to achieve good coronary flow because the thrombus was large and hard with a calcified surface revealed by intravascular ultrasound examination. Ultimately, compression of the thrombus with the AngioSculptTM scoring balloon catheter (AngioScore, Fremont, CA) led to resolution of normal coronary flow without the need for implantation of a coronary stent. Calcified thrombus is rarely observed in a coronary artery embolism, especially one formed in the left atrial appendage. In this case, the AngioSculpt scoring balloon catheter shows efficacy in treating this calcified thrombus. Copyright 2011 Wiley Periodicals, Inc.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Very Late Thrombosis in A Bare Metal Stent: Mechanistic analysis from optical coherence tomography

Jie Qian, MD, and Yue-Jin Yang, MD

Recent publications have emphasized the concept that restenosis of a bare metal stent (BMS) is not as clinically benign as previously believed. We present a case of very late stent thrombosis 9 years after implantation of a BMS is described. Optical coherence tomography shows plaque rupture in the stent. These findings suggest that the formation and progression of a neoatheroma over a previously healed intrastent vascular intima may represent a ‘‘new’’ mechanism for stent thrombosis. Evidence from the current case supports this hypothesis. Copyright 2011 Wiley Periodicals, Inc. Catheterization and Cardiovascular Interventions 79:288–290 (2012)

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Amplatzer Septal Occluder to Treat Iatrogenic Cardiac Perforations

Valérie Stolt, MD, Stéphane Cook, MD, Lorenz Räber, MD, Sunil Wani, MD, Ali Garachamani, MD, Rolf Vogel, MD, PhD, Christian Seiler, MD, Stephan Windecker, MD, and Bernhard Meier, MD

Iatrogenic free wall cardiac perforation is a rare but serious complication encountered during percutaneous cardiac procedures, which usually leads to tamponade and death. Septal occluder devices have been developed for sealing intracardiac shunts but may be also used in this emergency setting. Copyright 2011 Wiley Periodicals, Inc.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Embolization of an Amplatzer mVSD Occluder Device Used for Percutaneous Closure of an Ascending Aortic Pseudoaneurysm: Case Report and Literature Review

Stéphane Noble, MD and Réda Ibrahim MD

Pseudoaneurysm of the ascending aorta is a rare, but potentially dangerous condition. The high morbidity and mortality rate associated with its surgical management has led to the development of transcatheter approaches. We report a case of percutaneous closure of an ascending aortic pseudoaneurysm using an Amplatzer mVSD occluder device complicated by device embolization at day 27 and we review the literature of Amplatzer devices in this off-label use.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Combination Therapy Involving Stenting and Coil Embolization for Atherosclerotic Narrowing Complicated by a Coronary Aneurysm

Hirotaka Oda, MD, and Tomoyasu Suzuki, MD

There is controversy as to how atherosclerotic coronary artery aneurysms should be treated and managed because their prognosis is still unknown. This report describes a case in which atherosclerotic coronary narrowing accompanied by a saccular coronary aneurysm was successfully treated by combination therapy involving coil embolization to treat the aneurysm and stent implantation across the narrowing and the ostium of the aneurysm.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Transhepatic Closure of Patent Foramen Ovale

Neeraj Jolly, MD, Gaurav Dhar, MD, and Zahid Amin, MD

Transhepatic right heart catheterization is an uncommon procedure for adult interventional cardiologists. We report its successful use for closure of a patent foramen ovale in an elderly patient without femoral vein access. Also described is a novel method of using a vascular plug to achieve hemostasis of the hepatic venous access site. Copyright 2011 Wiley Periodicals, Inc.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. First-in-Man Case Report of the Use of an Edwards- Sapien Valve to Treat a Regurgitant CoreValve Aortic Valve Prosthesis

Maurizio Taramasso, MD, Andrew S.P. Sharp, MD, and Francesco Maisano, MD

Transcatheter aortic valve implantation is an alternative to conventional aortic valve replacement for patients at high surgical risk, with favorable procedural outcomes. Aortic regurgitation remains an off-label indication. Recent case reports describe the successful use of a second CoreValve inside a malpositioned first CoreValve. In the current case, we report for the first time a valve-in-valve procedure for the treatment of a severely insufficient CoreValve prosthesis using the Edwards-Sapien prosthesis.
