Some patients with severe angina have coronary artery disease which is unsuitable for conventional forms of revascularization — coronary angioplasty/ stenting or coronary artery bypass surgery. These patients have usually undergone previous revascularization procedures and have disease which is diffuse and affects the distal part of the coronary circulation. Transmyocardial laser revascularizat...

BACKGROUND Benefits of 2-dimensional (2D) angiosome-oriented infrapopliteal revascularization remain controversial. The aim of this retrospective study was to clarify the effect of single tibial artery revascularization on the dorsal and plantar microcirculation of critically ischemic limbs based on skin perfusion pressure (SPP). METHODS AND RESULTS Fifty-seven interventions that only involve...

UNLABELLED The prognostic value of myocardial viability assessment on left ventricular (LV) aneurysms remains undetermined. We aimed, first, to evaluate the long-term survival benefit of assessing the viability of the aneurysmal myocardium in patients with ischemic cardiomyopathy and, second, in the revascularization subgroup, to compare the short-term effects on LV function and clinical sympto...

The role of early coronary revascularization in the management of stable coronary artery disease remains controversial. The aim of this study was to evaluate the impact of early coronary revascularization on long-term outcomes (>10 years) after an ischemic dobutamine stress echocardiography (DSE) in patients with known or suspected coronary artery disease. Patients without stress-induced ischem...

OBJECTIVE Recommended timing of coronary revascularization after transmural acute myocardial infarction ranges from immediate surgical intervention to repair 4 weeks after infarction. Such wide variation has created a dilemma in the management of these patients. The objective of this study was to delineate the optimal timing of revascularization after transmural acute myocardial infarction in a...

BACKGROUND Recent clinical trials have demonstrated benefit with early revascularization following acute myocardial infarction (AMI). Trends in and the association between early revascularization after (ie, 30 days or fewer) AMI and early death were determined. METHODS AND RESULTS The Statistics Canada Health Person-Oriented Information Database, consisting of hospital discharge records for s...

Patients with heart failure symptoms due to ischemic cardiomyopathy face a poor prognosis without adequate treatment. In these patients with viable ischemic myocardium, revascularization surgery is not a new but an established treatment concept. the CASS study, published in 1983, was already able to document the superiority of coronary artery revascularization in patients with poor left ventric...

BACKGROUND The identification of hibernating myocardium is important in selecting patients who will benefit from coronary revascularization. This study was performed to determine whether dobutamine stress echocardiography (DSE) could identify hibernating myocardium and predict improvement in regional systolic wall thickening after revascularization. METHODS AND RESULTS DSE was performed in 49...

OBJECTIVES The purpose of this research was to perform a feasibility study of prophylactic coronary revascularization in patients with preoperative extensive stress-induced ischemia. BACKGROUND Prophylactic coronary revascularization in vascular surgery patients with coronary artery disease does not improve postoperative outcome. If a beneficial effect is to be expected, then at least those w...
