[Ultrasonic decalcification of the aortic valve. Initial experience].

We report our initial experience in 2 patients with degenerative calcific aortic stenosis who underwent ultrasonic debridement of the aortic valve. Compared with preoperative studies, doppler echocardiographic and hemodynamic evaluation before hospital discharge revealed a reduction in the mean aortic valve pressure gradient (80 and 65 mmHg to less than 10 mmHg). There was no change in aortic regurgitation grade. Follow-up doppler echocardiographic evaluation at four and six months showed no changes in gradient or regurgitation in the comparison to the postoperative data. Long-term results will show the convenience to attempt or not ultrasonic salvage of the native aortic valve in severe calcific stenosis.

[Percutaneous cardiopulmonary bypass in angioplasty and valvuloplasty. The technical considerations].

To reduce problems during percutaneous transluminal angioplasties and valvuloplasties in the catheterization laboratory, percutaneous cardiopulmonary bypass was used in 6 patients (three aortic, two mitral and one coronary). Percutaneous 21 F (venous) and 17 F (arterial) cannulas were placed through the femoral vessels. Mean flows of 3 l/min were achieved with a roller pump, with a mean blood pressure of 60 mmHg. Bypass time ranged between 22 and 55 minutes (mean 39). Light intravenous sedations and spontaneous breathing was maintained in all cases. Maximum inflation time of balloons were 4 minutes for the aortic valvuloplasty patients and 50 seconds for the mitral. Two patients developed groin hematomas, and one of them required surgical exploration. Percutaneous bypass is a simple and easily achieved technique to ensure safety in the high-risk patient.
