Is mitral valve repair safe procedure in elderly patients?

The aim of this randomized, prospective, study was to evaluate postoperative hospital mortality and morbidity after mitral valve repair by comparing two surgical techniques for resolving mitral valve insufficiency in elderly patients. In comparison were: mitral valve repair vs. mitral valve replacement in patients older than 70 years.

Off-pump versus on-pump--intermittent aortic cross clamping--myocardial revascularisation: single center expirience.

The aim of this randomised, prospective study was to evaluate hospital mortality and morbidity after myocardial revascularisation, comparing on-pump coronary artery bypass graft (CABG) myocardial revascularisation versus off-pump coronary artery bypass graft (OPCAB) myocardial revascularisation in population with multivessels coronary artery disease. Sixty patients with multivessels coronary artery diseases were scheduled to undergo coronary artery bypass grafting from January 15, 2006 to June 30, 2007 in our institution. Patients were randomized to off-pump or on-pump surgery with intermittent cross-clamping of aorta and ventricular fibrillation, using the envelope method with random numbers.
