T-stenting and small protrusion technique for left main coronary injury post Bentall procedure.

Coronary injury is a rare, but possible, complication of aortic root surgery. Conventional management may include modifying the coronary button or coronary artery bypass graft for the affected vessel. Described is a case of left main coronary artery injury occurring following a Bentall procedure successfully managed percutaneously with stenting.

Management of immediate partial bioresorbable vascular scaffold stent thrombosis.

Bioresorbable vascular scaffold (BVS) stents have been proposed recently as an elegant technique for treatment of coronary artery disease. However, perspective that these "dissolvable" stents will replace conventional metallic stents in broad spectrum of clinical conditions and patient categories in the near future has been moderated by non-negligible incidence of stent thrombosis (ST). Mechanical factors, such as strut thickness and malapposition have been implicated in increased risk of BVS ST.

The prognostic value of the cardiopulmonary exercise test in patients with heart failure who have been treated with beta-blockers.

Objectives: The prevalence of chronic heart failure and a reduced ejection fraction (CHF-REF) has increased over the last decade. The cardiopulmonary exercise test (CPET) is an established tool for managing these patients. For patients who are administered beta-blockers, its predictive value is debated.

Prinzmetal angina or coronary spasm related to anaphylactoid reaction?

Prinzmetal's angina is a challenging diagnostic of spontaneous brief episodes of chest pain. Anaphylactoid reactions to radiocontrast media are immediate hypersensitivity responses that can mediate coronary artery spasm. Herein, we report the case of a 61-year-old man who underwent a coronary angiography for angina.

An alternative approach in tortuous coronary artery and distal stenosis during transradial percutaneous coronary intervention: deep engagement by a 5-Fr guiding catheter.

Transradial approach for percutaneous interventions has emerged as an alternative to transfemoral access which is known to be more associated with vascular local complications. However, lack of guiding-catheter support via the radial access is one of the problems encountering the operators. Many solutions have been proposed to overcome this problem.
