Sostituzione valvolare mitro-aortica:fattori che influenzano il rischio operatorio.
No full text83 patients, 41 male and 42 female, mean age 54,04, operated on of mitro-aortic valve replacement from Jan 1982 to December 1987 were examinated to identify statistically significative operative risk factors. The vast majority of patients had calcific involvement of one (11,4%) or two (48,2%) valves; 7 cases underwent myocardial revascularization for concomitant coronary artery lesions and 17 (20,4%) had previously undergone cardiac operations. The hospital mortality was 8,4%, resulting significantly (p<0.05) influenced by more severe functional class of New Your Heart Association (NYHA) and by involvement of respiratory, renal and hepatic function; incremental risk factors for early mortality
Bypass aorto coronarico circolare: risultati immediati ed a distanza.
No full textAt Cardiovascular surgery department of Parma, from January 1984 through December 1985, myocardial revascularization with aortocoronary circular sequential vein graft technique was performed in 48 patients with severe and diffuse coronary stenosis and with saphenous vein with large caliber. There were no operative deaths, bypass/patient ratio was 5:1 and 6 patients underwent combined cardiovascular surgical procedures. The incidence of perioperative myocardial infarction was 4,1%. At mean follow-up interval of 37,35 mounths (ranging from 21 to 46) survival rate was 93,8% (1 non cardiac death occurring) and 4 patients (8,8%) had anginal recurrence medically treated. We concluded that in patients with clinical and perioperative features such as large saphenous vein, multiple distal coronary lesions, the aortocoronary circular bypass technique is indicated; moreover, because of its dependency on single proximal aortic connection this procedure should not been considered as an alternative method of myocardial revascularization, but can be used in selected coronarographic and intraoperative cases

Asymptomatic patient reoperated on for severe proximal stenosis of circular sequential vein graft.
No full textThe case is described of a fifty year old man who underwent coronary bypass surgery using the circular sequential vein graft technique. At follow-up study (6 months after operation), despite his asymptomatic status, the effort test revealed antero-lateral myocardial ischemia. A coronary angiography showed a 90% proximal stenosis of the graft at 1.5 cm from the aortic anastomosis. The patient was reoperated on and the circular graft was reconstructed. Despite the severe stenosis this technique of myocardial revascularization has developed intercoronary anastomoses, improving the cardiac contractility and avoiding further clinical complications
