Coronary artery bypass surgery with intermittent aortic cross-clamping.
Despite the generally accepted use of cardioplegia for myocardial protection during cardiac revascularization and other operations, non-cardioplegic methods have been used by many surgeons throughout the world. We have prospectively studied 229 patients consecutively subjected to isolated coronary artery bypass surgery from March 1990 to February 1991 by a single surgeon who used intermittent a...
متن کاملDealing with a Porcelain Aorta during Coronary Artery Bypass Grafting
We report a complex case of multivessel CAD in a patient with a porcelain aorta and high-grade left subclavian artery stenosis. Utilizing a staged left subclavian artery stent placement with a next-day plan for a four-vessel, on-pump CABG and ascending aortic replacement, this case highlights an organized approach to diagnosing and dealing with a heavily calcified aorta while describing a stepw...
متن کاملMyocardial protection with prophylactic oral metoprolol during coronary artery bypass grafting surgery: evaluation by troponin I
INTRODUCTION Biochemical markers of myocardial injury are frequently altered after cardiac surgery. So far there is no evidence whether oral beta-blockers may reduce myocardial injury after coronary artery bypass grafting. OBJECTIVE To determine if oral administration of prophylactic metoprolol reduces the release of cardiac troponin I in isolated coronary artery bypass grafting, not complica...
متن کاملMyocardial ischemia due to infrarenal aortic cross-clamping during aortic surgery in patients with severe coronary artery disease.
Hemodynamic measurements were performed and ECG recorded before and shortly after infrarenal aortic cross-clamping during operation for abdominal aortic aneurysm in five patients without evidence of heart disease (group I) and in ten patients with severe coronary artery disease (group II). All patients sustained an increase in systemic arterial pressure. Group I demonstrated a decrease in pulmo...
متن کاملDoes preoperative beta-blocker offer myocardial protection during coronary artery bypass grafting?
The past two decades have seen a number of studies being carried out in order to investigate the use of beta-blockers as myocardial protection in patients who undergo great surgical stress and are under significant risk factors, especially in non-cardiovascular surgery regarding major adverse cardiac events (MACE) and death [1,2]. During meta-analysis published in 2010, which included the patie...
