CO measurements were performed simultaneously by three different contributors and were collected by the fourth one 24 h postoperative in the intensive care unit (ICU).

786T/c endothelial nitric oxide synthase gene polymorphism and coronary collateral circulation.

Introduction: In this study, we investigated the association between -786T/C polymorphism of the endothelial nitric oxide (NOS3) gene in which thymidine is replaced by a cytosine at nucleotide -786 (rs 2070744) and coronary collateral circulation (CCC) in patients with stable coronary artery disease.

Materials And Methods: 286 patients having a critical stenosis (> 95%) in at least one major epicardial coronary vessel were included in the study. CCC was defined according to the Rentrop classification (R).

Transcatheter aortic valve implantation in a patient with bicuspid aortic stenosis and a borderline-sized annulus.

Bicuspid aortic valve (BAV) is currently considered an exclusion criterion for transcatheter aortic valve implantation (TAVI). The risk of adverse aortic events such as incomplete sealing, severe paravalvular regurgitation or dislocation due to elliptic shape and asymmetric calcifications in annulus are higher in TAVI. In this case report, we detailed a case of successful trans-femoral TAVI in a 51-year old male with BAV and its management without in-hospital and 30-day complications.

Comparison of Effects of Low- versus High-Dose Heparin on Access-Site Complications during Transradial Coronary Angiography: A Double-Blind Randomized Study.

Objectives: Although heparin is highly effective in reducing the rate of radial artery occlusion after transradial catheterization, the optimal heparin dose is still controversial. The aim of this study was to evaluate the efficacy and safety of two different heparin doses during transradial coronary angiography.

Methods: 490 consecutive patients undergoing transradial coronary angiography were prospectively enrolled into this double-blind randomized trial.

Impact of QRS duration on survival benefit with prophylactic implantable cardioverter-defibrillators: a meta-analysis of randomized controlled trials.

Background: QRS duration is an important risk factor for both sudden cardiac death and all-cause mortality in patients with moderate to severe left ventricular systolic dysfunction. However, it is unknown whether baseline QRS duration can help predict the mortality benefit from implantable cardioverter-defibrillators (ICDs) when used for primary prevention purposes.

Objective: Our objective was to examine the relationship between baseline QRS duration and mortality reduction with ICDs implanted for primary prevention by performing a meta-analysis of all available randomized clinical trials.

Right ventricular endomyocardial fibrosis mimicking Ebstein anomaly in a patient with Behçet's disease: case report and review of the literature.

Behçet's disease is a multisystemic, chronic inflammatory disorder with diffuse clinical manifestations including the cardiovascular system. Endomyocardial fibrosis is a rarely seen complication of Behçet's disease leading to progressive heart failure. We report a case of right ventricular endomyocardial fibrosis mimicking Ebstein anomaly in a 26-year-old male Turkish patient with Behçet's disease, who had heart failure symptoms.

Coronary artery bypass grafting vs percutaneous coronary intervention and long-term mortality and morbidity in multivessel disease: meta-analysis of randomized clinical trials of the arterial grafting and stenting era.

Importance: Recent trials of percutaneous coronary intervention (PCI) vs coronary artery bypass grafting (CABG) for multivessel disease were not designed to detect a difference in mortality and therefore were underpowered for this outcome. Consequently, the comparative effects of these 2 revascularization methods on long-term mortality are still unclear. In the absence of solid evidence for mortality difference, PCI is oftentimes preferred over CABG in these patients, given its less invasive nature.

A hybrid therapy as a third approach for type 1 proximal endoleak of thoracic endovascular aortic replacement: Caroticocarotid bypass and re-redo endovascular therapy.

Introduction: In selected cases with thoracic aortic aneurysm (TAA), thoracic endovascular aortic replacement (TEVAR) is commonly used and shall be proper therapy method. We are presenting a case of TAA previously treated twice by endovascular aortic approaches and complicated by type 1 endoleak.

Case: A 67-year-old male patient was admitted to our clinic with back pain at rest.

The long-term incidence and predictors of radial artery occlusion following a transradial coronary procedure.

Background: Radial artery occlusion (RAO) is an infrequent complication of transradial coronary procedures (TRA). To our knowledge, there is no satisfactory data regarding the late term incidence and predictors of RAO in the literature. Our aim was to establish the long-term incidence of radial artery occlusion and investigate its predictors.

Management of an iatrogenic radial artery perforation: a case report.

A 73-year-old female patient underwent transradial coronary angiography with stable angina and signs of significant myocardial ischemia revealed by exercise stress test. After insertion of a 6F radial sheath into the right radial artery and intra-arterial administration of heparin plus verapamil, the hydrophilic guidewire could not be advanced under fluoroscopic guidance. Immediately afterwards, radial angiography was performed, which displayed a radial artery perforation with significant contrast extravasation.

Concomitant complete atrioventricular block and left main coronary artery occlusion during transcatheter aortic valve implantation.

Transcatheter aortic valve implantation (TAVI) is now considered a viable alternative therapy to surgery in patients with severe symptomatic aortic stenosis, considered to have a high risk for surgery. Herein, we present a case of severe aortic stenosis treated with transfemoral aortic valve implantation and complicated by complete atrioventrciular block and left main coronary artery obstruction that was successfully managed with permanent pacemaker implantation and left main coronary artery stenting. Although less invasive, TAVI can be associated with major complications.
