ABSTRACT: The marked reduction of in-stent restenosis of drug-eluting stents (DES) has dramatically affected modern interventional therapy for coronary artery disease. The promises of this potential panacea, however, have been recently attenuated by…
ABSTRACT: Left ventricular apical ballooning is an increasingly reported phenomenon with an onset that is usually triggered by severe and often acute emotional incidents. We report a rare case of acute left ventricular apical ballooning syndrome, mim…
J INVASIVE CARDIOL 2007;19:E375–E377 Angina is a common symptom among patients with primary and secondary pulmonary arterial hypertension and has commonly been attributed to right ventricular (RV) ischemia due to RV dilatation and hypertrophy.1–2 Th…
ABSTRACT: Current guidelines recommend implantation of permanent pacemakers for advanced atrioventricular block complicating acute myocardial infarction (MI) when the block is present beyond the usual hospital course. In patients with inferior MI, su…
ABSTRACT: Complications of percutaneous coronary intervention include in-stent restenosis (ISR) and in-stent thrombosis (IST) which have different underlying pathophysiological processes and different treatment strategies. ISR is primarily due to exc…
ABSTRACT: Systemic complications of native-valve endocarditis include embolism, abscess formation and development of mycotic aneurysms. To date, only two cases of mycotic coronary aneurysm (MCA) detected by transesophageal echocardiography (TEE) have…
ABSTRACT: The inability to cross tortuous, calcified or previously stented segments with an angioplasty balloon or coronary stent remains one of the frequent causes of the procedural failure. Numerous techniques have been developed to facilitate sten…
ABSTRACT: Calcified lesions are a cause of stent underexpansion which significantly increases the subsequent risks of in-stent restenosis and thrombosis, even when drug-eluting stents are used. In this report, we describe a novel balloon catheter (Sa…
ABSTRACT: Stent underexpansion is a catastrophic complication of stent implantation that can usually be treated with high-pressure balloon dilatation. We report a case of emergency, unprotected distal left main coronary artery stenting, in which the…
ABSTRACT: Background. Stents are used to treat the first and even successive episodes of in-stent restenosis (ISR). Methods. In 18 patients (19 lesions), intravascular ultrasound (IVUS) was performed after placement of a stent for a nonrestenotic les…
