OBJECTIVES This study was performed to assess the prognostic implications of myocardial contractile reserve (MCR) in patients with coronary artery disease (CAD) and left ventricular (LV) dysfunction. BACKGROUND MCR during dobutamine stress echocardiography (DSE) identifies viable myocardium that may improve in function after revascularization. Whether revascularization influences prognosis of...
Despite impressive advances in stent technology, unprotected left main coronary artery (LMCA) disease requiring revascularization remains the province of the surgeon at most institutions. In a 2007 editorial, we summarized the evolution of percutaneous coronary intervention (PCI) for LMCA disease, concluding that given the available evidence at that time, coronary artery bypass graft surgery (C...
BACKGROUND Penetration of fractional flow reserve (FFR) in clinical practice varies extensively, and the applicability of results from randomized trials is understudied. We describe the extent to which the information gained from routine FFR affects patient management strategy and clinical outcome. METHODS AND RESULTS Nonselected patients undergoing coronary angiography, in which at least 1 l...

Cardiac allograft vasculopathy is the leading cause of death after the first year of heart transplantation. The optimal treatment for unprotected left main coronary artery disease in orthotopic heart transplantation (OHT) patients is unknown. Two OHT patients with left main disease following heart transplantation underwent percutaneous coronary intervention (PCI). Technical success was achieved...

The left internal thoracic artery is usually used as arterial conduit for myocardial revascularization; however, there is an increasing popularity of bilateral use of this artery for grafting. We examined 180 patients with both types of arterial conduits to answer whether bilateral use of the internal thoracic artery makes the difference in postoperative extubation outcome and duration of hospi...
BACKGROUND The purpose of this study was to evaluate early and late results of reoperative coronary artery bypass grafting compared with those of first coronary artery bypass grafting. METHODS From November 21, 1994, to December 31, 2001, 4,381 patients underwent isolated coronary revascularization: among these patients, 274 (6.3%) underwent a redo. Applying the propensity score, 239 redo pat...
The prognosis for patients with chronic ischemic left ventricular dysfunction is poor, despite advances in different therapies. Noninvasive assessment of myocardial viability may guide patient management. Multiple imaging techniques have been developed to assess viable and nonviable myocardium by evaluating perfusion, cell membrane integrity, mitochondria, glucose metabolism, scar tissue, and c...
M e t h o d s Design: Randomized controlled trial (Second Randomized Intervention Treatment of Angina [RITA-2] Trial). Allocation: {Concealed}†.* Blinding: Blinded (outcome assessors).* Follow-up period: Median 7 years. Setting: 20 centers in the United Kingdom and Ireland. Patients: 1018 patients > 18 years of age (median age 58 y, 82% men) with arteriographically proven coronary artery diseas...
