Percutaneous Balloon Aortic Valvuloplasty for Aortic Stenosis in Elderly Patients at High Risk for Surgery

摘要: Six elderly patients had percutaneous balloon aortic valvuloplasty for severe, symptomatic calcific stenosis because valve replacement surgery was considered too risky in five with severe coexisting cardiac or other medical problems and one patient refused to have surgery. The procedure resulted a significant reduction the mean (+/-SD) gradient, from 47 +/- 13 32 12 mm Hg (change, -32%, p less than 0.01), increase area of valve, 0.64 0.12 0.90 0.17 cm2 +40%, 0.001). Blood loss femoral puncture site only major procedural complication. At follow-up 2 months after procedure, all were alive dyspnea improved by two New York Heart Association functional classes four class patients. A short-term alleviation symptoms can be achieved safely who are at high risk surgical complications.
