The TIMI frame count (TFC) is an index of coronary blood flow, and a correction in TFC (CTFC) for left anterior descending artery (LAD) has also been proposed. However, the relationship between TFC and intravascular ultrasound (IVUS) parameters of culprit coronary arteries has not been reported. The aim of this study was to investigate IVUS-derived correlates of TFC before and after stenting, a...

Case presentation A: A 50-year-old diabetic man presented to the hospital after 8 hours of continuous chest pain. Because of acute myocardial infarction of the anterior wall, he underwent direct stenting to an occlusion in the left anterior descending coronary artery. Despite revascularization, suboptimal coronary flow was achieved, and he subsequently developed heart failure. Case presentation...

OBJECTIVE To investigate the efficacy of coronary stenting in patients with variant angina refractory to medical treatment. SUBJECTS AND METHODS Variant angina was diagnosed in 81 patients admitted to the Department of Cardiology between January 2003 and June 2011. However, coronary stenting was performed in 21 patients refractory to medical treatment, but coronary angiography and intravascul...

Study selection Comparative studies of percutaneous coronary stenting versus coronary artery bypass grafting that enrolled patients with unprotected left main coronary artery stenosis were eligible for inclusion. Eligible studies had to provide adjusted hazard ratios (HRs) for mortality with at least one year of follow-up. Studies from which hazard ratios or risk estimates could not be extracte...

We report a case of treatment of subclavian-coronary steal syndrome with stenting and immediate improvement of left internal mammalian artery flow.

A patient developed hemopericardium shortly after left brachial arterial embolectomy using an embolectomy catheter. Evaluation disclosed evolving pseudoaneurysm of the right coronary artery that was successfully managed by stenting. Misplacement of the embolectomy catheter within the coronary vessel was facilitated by an anomalous origin of the right coronary artery. This complication highlight...

IntRoductIon In current catheter research, there are 3 main directions with respect to fractional flow reserve (FFR), including instantaneous wave‐free ratio, noninvasive measurement of FFR, and FFR transferred from coronary circulation to other ischemia‐inducing circulation. Recently, an interesting study was published, in which FFR was performed to diagnose and guide stenting in chronic mesen...

Intravascular ultrasound examination (ICSI) allows to assess the nature of atherosclerotic plaque, degree significance and extent stenosis, as well monitor position stent in lumen coronary artery. Insufficient opening stent, unrecognized during angiographic control, can lead thrombosis or restenosis early long term. The clinical case presented publication demonstrates difference between results...

F or several decades, bypass surgery has been regarded as the treatment of choice for patients with unprotected left main coronary artery (LMCA) disease. However, because of easy anatomic accessibility and a relatively large vessel caliber, left main percutaneous coronary intervention (PCI) for LMCA disease has become an attractive option for cardiologists. In addition, technical advances in PC...
