BACKGROUND: Data regarding bioresorbable vascular scaffolds (BVS) use in coronary bifurcation lesions are limited. The aim of this study was to compare mid-term clinical outcomes of all-comer patients treated with BVS versus everolimus-eluting stents (EES) for bifurcation lesions. METHODS: A total of 351 non-left-main bifurcation lesions in 323 all-comer patients were treated either with BVS (166 bifurcations in 147 patients) or EES (185 bifurcations in 176 patients)...

Contrast-induced nephropathy (CIN) is a serious complication in patients undergoing percutaneous coronary intervention (PCI), and is associated with higher morbidity and mortality. The limiting volume of contrast medium is safest and most reliable strategy for CIN prevention. Intravascular ultrasound (IVUS) serves as an attractive alternative imaging tool to angiography in many steps during PCI, thereby reducing the use of contrast agents. Here, we reported a case of successfully treated unprotected left main bifurcation lesion with heavily calcified and diffuse lesion under the IVUS-guided PCI using low volumes of contrast dye of total 12 cc in an elderly patient...

BACKGROUND AND AIM: 25-hydroxyvitamin D deficiency represents a widespread social problem but also an emerging risk factor for cardiovascular disease. Genetic variants of the Vitamin D Binding Protein (VDBP), the main transporter of vitamin D in the bloodstream, have been shown to account for a significant variability in the levels and systemic effects of vitamin D. We investigated whether the single nucleotide polymorphisms, rs7041 and rs4588, of VDBP are associated to the prevalence and extent of coronary artery disease...

Catheter-induced coronary dissection involving left main bifurcation is a rare complication during cardiac catheterization but can become lethal unless it is treated appropriately. Interventional cardiologists always have to pay attention to the risk of complications related to cardiac catheterization and prepare for determining the best bailout strategy for the situation.

OBJECTIVES: Percutaneous coronary intervention (PCI) of the left main (LM) or proximal left anterior descending artery (pLAD) is considered high-risk as these segments subtend substantial left ventricular myocardial area. We assessed the patterns and associations between dual antiplatelet therapy (DAPT) cessation and 2-year outcomes in LM/pLAD vs. other PCI from the all-comer PARIS registry. METHODS: Two-year major adverse cardiovascular events (MACE) were a composite of cardiac death, myocardial infarction, definite/probable stent thrombosis or target lesion revascularization...

With significant improvements in percutaneous coronary intervention (PCI) technology, complex high risk PCI is increasingly offered to patients with limited revascularization options. Percutaneous mechanical circulatory support devices are often utilized for hemodynamic support during these complex procedures. Veno-arterial extracorporeal membrane oxygenation (ECMO) allows full hemodynamic support and provides systemic oxygenation. We describe a case of left main bifurcation stenting performed at our center with ECMO support in an awake patient without general anesthesia...

Low reliability and reproducibility in heart failure models are well established. The purpose of the present study is to explore factors that affect model consistency of myocardial infarction (MI) in mice. MI was induced by left coronary artery (LCA) ligation. The coronary artery was casted with resin and visualized with fluorescent imaging ex vivo. LCA characteristics and MI size were analyzed individually in each animal, and MI size was correlated with left ventricular (LV) function by echocardiography. Coronary anatomy varies widely in mice, posing challenges for surgical ligation and resulting in inconsistent MI size postligation...

Interventional cardiologists still rely heavily on angiography for the evaluation of coronary lesion severity, despite its poor correlation with the presence of ischemia. In order to improve the accuracy of the current diagnostic procedures, an understanding of the relative influence of geometric characteristics on the induction of ischemia is required. This idea is especially important for coronary bifurcation lesions (CBLs), whose treatment is complex and is associated with high rates of peri- and post-procedural clinical events...

Coronary artery aneurysm is rare, and there is no established protocol for surgical indication. On preoperative examination of orthopedic surgery, a 76-year-old male was found with asymptomatic myocardial ischemia. Radiological examinations revealed triple vessel disease and a coronary artery aneurysm, 10 mm in size, at the bifurcation of the left main trunk. Combined with quintuple coronary artery bypass grafting, surgical repair of the aneurysm was peformed under cardiopulmonary bypass on beating heart. Epicardial echocardiography was used to detect the site and the blood flow on the aneurysm...

We evaluated the correlation of the left main coronary bifurcating angle (LCBA) with the severity of coronary atherosclerosis, risk factors of coronary artery disease (CAD) and the feasibility of measuring the LBCA using the axial plane. Coronary Computed tomography angiographies (CTAs) of 313 patients between Nov. 2006 and Oct. 2013 were reviewed and separated into three groups. Group I (211 patients) had significant stenosis (≥50%) of the left anterior descending coronary artery (LAD) and/or left circumflex coronary artery (LCX)...

Local hemodynamics has been identified as one main determinant in the onset and progression of atherosclerotic lesions at coronary bifurcations. Starting from the observation that atherosensitive hemodynamic conditions in arterial bifurcation are majorly determined by the underlying anatomy, the aim of the present study is to investigate how peculiar coronary bifurcation anatomical features influence near-wall and intravascular flow patterns. Different bifurcation angles and cardiac curvatures were varied in population-based, idealized models of both stenosed and unstenosed bifurcations, representing the left anterior descending (LAD) coronary artery with its diagonal branch...

Coronary trifurcation lesions are a complex subset of lesions and are substantially more complex than bifurcations when treated with percutaneous coronary intervention (PCI) because of higher rates of acute periprocedural complications (dissection, myocardial infarction, acute vessel closure) and less effective long-term outcomes (stent thrombosis, restenosis) as compared to non-bifurcation lesions. We present the case of a 73-year-old man who was admitted to our hospital with symptomatic severe aortic stenosis who was found to have a distal left main trifurcation disease as well as porcelain aorta on work-up...
