Immediate morbidity and hospital mortality in the valvular mitral replacement with a mechanical prosthesis Valvular mitral surgery accounts for the fourth part of the operations performed at the Institute of Cardiology and Vascular Surgery . 80 % of them correpond to valvular mitral replacement. No national morbidity and mortality studies have been published yet. A prospective study of 301 patients who underwent valvular mitral replacement at this institute from January, 1996, to May, 2001, was conducted. The most frequent postoperative complications were: auricular fibrilation (78 patients, 26.3 %); low cardiac output (53 patients, 17.8 %) and excessive bleeding (48 patients, 16.2 %). Hospital mortlaity was 19.0 % (27 patients). It was concluded that morbidity and mortlity are acceptable and that emphasis should be made on the prevention, diagnosis and early treatment of the complilcations
