Cardiac Surgery Factors Correlating With Risk of Mortality After Transmyocardial Revascularization

چکیده
METHODS One hundred thirty-two patients with severe angina underwent TMR as sole therapy with a CO2 laser. Age, gender, ejection fraction, prior CABG, unstable angina and the severity of coronary artery disease (graded on the basis of a newly proposed Anatomic Myocardial Perfusion index, AMP) were each determined. Each vascular territory (left anterior descending artery [LAD] left circumflex artery and posterior descending artery [PDA]) was graded as either having (AMP 5 1) or not having (AMP 5 0) blood flow through an unobstructed major vessel in the territory. Univariate and multivariate analysis determined which factors correlated with mortality.

Factors correlating with risk of mortality after transmyocardial revascularization.
OBJECTIVES The purpose of this study was to determine factors correlating with the risk of postoperative mortality after transmyocardial laser revascularization (TMR). BACKGROUND Clinical studies have indicated that TMR reduces angina by an average of two classes in patients with medically refractory symptoms not treatable by coronary artery bypass graft (CABG) or percutaneous transluminal co...

OBJECTIVES The purpose of this study was to describe the incidence and spectrum of perioperative cardiac and noncardiac morbidity and mortality after transmyocardial laser revascularization (TMR) and to identify predictors of these adverse clinical events. BACKGROUND Clinical studies have demonstrated the efficacy of TMR for relieving angina pectoris, although no study to date has specificall...

BACKGROUND Patients with chronic severe angina refractory to medical therapy who cannot be completely revascularized with either percutaneous catheter intervention or coronary artery bypass graft surgery present clinical challenges. Transmyocardial laser revascularization, either as sole therapy or as an adjunct to coronary artery bypass graft surgery, may be appropriate for some of these patie...

OBJECTIVES We sought to examine trends in the use and outcomes of transmyocardial revascularization (TMR) in community practice. We also identified important risk factors for TMR and compared outcomes of TMR combined with coronary artery bypass graft surgery (TMR + CABG) versus bypass alone in patients receiving incomplete revascularization. BACKGROUND Although it is approved for use as a sta...

Background: Peripheral arterial disease is a source of morbidity and mortality. Surgical vascular reconstruction is a treatment option but probability of failure and complications are important concerns. In this study, we evaluated outcome of surgical infrainguinal reconstruction and factors affecting graft patency for a period of one year. Methods: In this cohort study, 85 consecutive patie...
