Background: The impact of changing demographics on causes of long-term death after percutaneous coronary intervention (PCI) remains incompletely defined.
Objectives: To characterize the prevalence of thrombus burden, collateral vessels to the infarct-related artery, epicardial coronary artery flow, and myocardial perfusion in patients with angiographically confirmed definite stent thrombosis (ST), and to define their relationship with associated treatments and outcomes.
Background: Preoperative bridging with a glycoprotein IIb/IIIa inhibitor is often performed in patients with prior coronary stents undergoing surgery who require antiplatelet therapy discontinuation, but its safety and efficacy have received limited study. We performed a weighted meta-analysis of the outcomes in patients with coronary stents undergoing bridging with glycoprotein IIb/IIIa inhibitors prior to surgery.
Objective: Optimal duration of dual antiplatelet therapy (DAPT), defined as use of both aspirin and a P2Y12 receptor inhibitor, after implantation of drug eluting stents (DES) is still subject of ongoing debate. We systematically review efficacy and safety of ≤6 months versus ≥12 months DAPT after implantation of DES.
Aims: Previous studies reported that integrated backscatter intravascular ultrasound (IB-IVUS) provides high diagnostic accuracy for tissue characterization of coronary plaques and that pregnancy-associated plasma protein A (PAPP-A) could be a marker of adverse cardiac outcome in patients with cardiovascular disease. We examined whether IB-IVUS and PAPP-A levels could predict the incidence of no-reflow during percutaneous coronary intervention (PCI)
Objectives: The aim of this study was to assess the impact of bleeding after percutaneous coronary intervention (PCI) with drug-eluting stents on long-term clinical events according to the newly proposed Bleeding Academic Research Consortium (BARC) classification.
Objective: To assess the differences in clinical outcome between complex patients treated with Resolute zotarolimus-eluting stents (ZES) versus Xience V everolimus-eluting stents (EES).
Objectives: This study explores bleeding risk of warfarin patients undergoing radial catheterization.
Abstract: The transradial (TR) approach for coronary angiography and intervention is increasingly used worldwide because of several advantages such as reduced bleeding and vascular complications. During TR procedures, aggressive catheter manipulation in the setting of complex and tortuous arterial anatomy can lead to catheter kinking and entrapment. Several percutaneous retrieval techniques using either homolateral radial access or femoral access have been described previously. We demonstrate, for the first time, the use of a sheathless guide catheter as a rescue technique to successfully retrieve a severely kinked and entrapped diagnostic catheter during TR access. © 2014 Wiley Periodicals, Inc.
Background: Data are limited regarding transcatheter aortic valve replacement (TAVR)-related thrombocytopenia (TP). We sought to thoroughly characterize the presence, clinical impact, and severity of TP associated with TAVR.
Objectives: We sought to investigate the magnitude and clinical importance of thrombocytopenia post transcatheter aortic valve replacement (TAVR).
Abstract: Iatrogenic membranous ventricular septal defects (VSD) are rare complications of cardiothoracic surgery, most commonly seen as a complication of aortic valve replacements. An iatrogenic VSD can lead to right sided heart failure, systemic hypoxia, and arrhythmias, and closure is often necessary. Given the increased mortality associated with repeat surgical procedures, percutaneous transcatheter closure of these iatrogenic VSDs has increasingly become the preferred choice of therapy. We describe the first case of iatrogenic membranous VSD in the setting of mitral valve replacement and tricuspid valve repair, using the newly approved Amplatzer Duct Occluder II Device from an entirely retrograde approach. © 2014 Wiley Periodicals, Inc.
Objective: We report a case of a 52-year-old female patient with perforated sinus of Valsalva (SVA) aneurysm presenting with severe left-to-right shunt from the aorta into the right ventricle.
Abstract: Surgical repair is considered the gold standard in severe mitral valve regurgitation. Multi-organ failure because of acute mitral insufficiency, however, can be challenging to manage as it aggravates to an inoperable state. We report the case of a 59 year old woman who presented with pulmonary oedema because of high grade mitral regurgitation. A recompensation prior to surgery using medical therapy failed and the patient developed a progressive multi-organ failure including pulmonary, circulatory, and renal failure within days. Symptomatically, our patient could be stabilized employing an extracorporeal membrane oxygenation and an intra-aortic balloon pump. A surgical mitral valve repair was ruled out because of the multi-organ failure. We performed an interventional valve reconstruction using the MitraClip™ device continuing the extracorporeal membrane oxygenation and the intra-aortic balloon counterpulsation therapy during the procedure. After clipping, multi-organ failure regressed and the extracorporeal membrane oxygenation could be explanted at day two after intervention. © 2013 Wiley Periodicals, Inc.
Objective: We sought to investigate the relationship between the SYNTAX score (SS) and stent thrombosis (ST) in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) undergoing percutaneous coronary intervention (PCI).
