Background—Despite worse outcomes in diabetics after coronary artery bypass grafting surgery, studies have not examined graft patency in this high-risk group. This study examined the impact of diabetes on graft patency, 1-year postcoronary artery bypass grafting, using data from a multicenter randomized trial. Methods and Results—The Radial Artery Patency(More)
BACKGROUND Cardiac ganglia were originally thought to contain only cholinergic neurons relaying parasympathetic information from preganglionic brain stem neurons to the heart. Accumulating evidence, however, suggests that cardiac ganglia contain a heterogeneous population of neurons that synthesize or respond to several different neurotransmitters and(More)
BACKGROUND The purpose of this study was to compare the long-term results of tricuspid valve (TV) repair with or without an annuloplasty ring. METHODS AND RESULTS 702 patients underwent TV repair at our institution (1978 to 2003), of which 493 had, predominantly, a De Vega procedure (no ring) and 209 had an annuloplasty ring (ring). TV pathology was(More)
BACKGROUND Cardiac resynchronization therapy (CRT) alone or combined with an implantable defibrillator (CRT-D) has been shown to improve exercise capacity and quality of life and to reduce heart failure (HF) hospitalizations and mortality in patients with New York Heart Association (NYHA) class III and IV HF. There is concern that the device procedure may(More)
For more than 30 years, heart transplantation has been a successful therapy for patients with terminal heart failure. Mechanical circulatory support (MCS) was developed as a therapy for end-stage heart failure at a time when cardiac transplantation was not yet a useful treatment modality. With the more successful outcomes of cardiac transplantation in the(More)
Not applicable. Text The phase one results from the randomized Radial artery versus Saphenous Vein Patency (RSVP) trial are published in the current issue of the Journal [1]. Fifty-two patients had quantitative angiography with Thrombolysis in Myo-cardial Infarction (TIMI) flow assessment, approximately 3 months after coronary bypass graft surgery. A subset(More)
