BACKGROUND Remote ischemic preconditioning may result in reduction in infarct size during percutaneous coronary intervention (PCI). It is unclear whether remote ischemic postconditioning (RIPost) will reduce the incidence of myocardial injury after PCI, and whether ischemic conditioning of a larger remote organ (thigh versus arm) would provide further(More)
OBJECTIVE Traditionally integrated coronary artery revascularization has been described as a 2-stage procedure. We evaluated the safety and feasibility of 1-stage, simultaneous, hybrid, robotically assisted coronary artery bypass grafting surgery and percutaneous coronary intervention. METHODS Fifty-eight patients underwent simultaneous, integrated(More)
INTRODUCTION The aim of this study was to assess the safety and feasibility of catheter-based cryothermal ablation lesions in the mid- and distal coronary sinus. METHODS AND RESULTS Cryothermal ablation lesions were delivered using a 7-French catheter at the mid- (n = 13) and distal (n = 12) coronary sinus in 14 swine under general anesthesia. Lesions(More)
OBJECTIVES Hybrid coronary revascularization, performing a left internal thoracic artery (LITA) to left anterior descending (LAD) bypass followed by percutaneous coronary intervention (PCI) in a non-LAD coronary artery lesion, represents an evolving revascularization strategy. It utilizes the survival benefit of the LITA-to-LAD bypass, while providing(More)
BACKGROUND Contrast-induced nephropathy (CIN) is an important cause of iatrogenic morbidity and mortality. The amount of contrast delivered has a major effect on CIN and is operator-dependent. A few studies suggested that the use of automated contrast injection systems is associated with reduced contrast volume. It is unknown whether this is true when(More)
Transcatheter aortic valve implantation (TAVI) in the presence of a mechanical mitral valve (MMV) prosthesis is still challenging because of the rigid mitral frame within the aortomitral curtain. Moreover, low-lying coronary ostia represent a hazardous problem of coronary obstruction, especially in narrow or porcelain aortic roots. The present case(More)
BACKGROUND Transcatheter aortic valve implantation (TAVI) has become a therapeutic alternative for patients presenting with severe symptomatic aortic stenosis and considered at high-surgical risk. Paravalvular leak (PVL), conduction disorders, and coronary obstruction remain unresolved procedure-related complications. The aim of this manuscript was to(More)
BACKGROUND Preimplantation balloon aortic valvuloplasty (BAV) is considered a routine procedure during transcatheter aortic valve implantation (TAVI) to facilitate prosthesis implantation and expansion; however, it has been speculated that fewer embolic events and/or less hemodynamic instability may occur if TAVI is performed without preimplantation BAV.(More)
Cardiac tamponade is a rare, life-threatening complication of hemophilia. The management of pericardial bleeding in hemophilia A patients with inhibitors is particularly challenging because antibodies to factor (F) VIII render the use of high-dose FVIII ineffective. Fortunately, the management of uncontrollable bleeding in patients with hemophilia and(More)
