| Popis: | Relative contraindications to coronary angioplasty have been large amounts of jeopardized myocardium and poor left ventricular function. To prevent possible hemodynamic collapse after balloon occlusion or acute vessel closure in such high risk patients, a cardiopulumonary bypass system capable of providing up to 6 liters/min output was employed prophylactically. This technique, termed supported angioplasty, results in reductions of preload and afterload and allows prolonged balloon inflations in critical coronary vessels.A National Registry of 14 centers performing elective supplied angioplasty was formed to collate the initial experience with high risk patients. Suggested indications were ejection fraction 75 years of age and had left main coronary artery stenosis. Patients without these two factors had a hospital mortality rate of 2.6%. Symptomatic improvement (lessening of New York Heart Association chest pain classification by at least two classes) occurred in 91% of the patients surviving hospitalization. During the follow-up period of 1 to 12 months, three patients died of cardiac complications.This multicenter experience suggests that supported angioplasty can be safely performed with the expectation of good symptomatic improvement and short-term survival in high risk patients other than elderly individuals with left main coronary artery stenosis. |
