OBJECTIVES: The authors sought to examine outcomes and identify independent predictors of mortality among patients undergoing urgent/emergent transcatheter aortic valve replacement (TAVR). BACKGROUND: Data on urgent/emergent TAVR as a rescue therapy for decompensated severe aortic stenosis (AS) are limited. METHODS: The Society of Thoracic Surgeons and the American College of Cardiology Transcatheter Valve Therapy (STS/ACC TVT) Registry linked with Centers for Medicare & Medicaid Services claims was used to identify patients who underwent urgent/emergent versus elective TAVR between November 2011 and June 2016...

Percutaneous coronary interventions (PCIs) in diabetic patients with small reference diameter vessels remain an important challenge in interventional cardiology because it is associated with increased complications and restenosis rates. Plain old balloon angioplasty (POBA) has limited efficacy in patients with lesions in small vessels. Although coronary stenting (stent) has been demonstrated to improve both immediate and long-term results after coronary intervention, small reference diameter is a strong predictor of restenosis after stent implantation...

Management of in-stent restenosis has become a significant challenge in interventional cardiology. Since the mechanism of in-stent restenosis is predominantly intimal hyperplasia, debulking techniques have been used to treat this condition. This study is a nonrandomized comparison of the immediate and long-term results of directional coronary atherectomy (DCA; n = 58) vs. high-speed rotational atherectomy (ROTA; n = 61) for the treatment of in-stent restenosis of native coronary arteries. There were no in-hospital deaths, Q-wave myocardial infarctions, or emergency coronary artery bypass surgery in either group...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
