Abstract:
Out of 104 patients with perimembranous or infundibular-isolated ventricular septal defect (VSD), causative factors of Prol and AR, and the operative indication were studied in 17 with prolapse of the aortic cusp (Prol) and 10 with aortic valve regurgitation (AR). The left to right shunt ratio and the size of VSD were smaller in patients with Prol or AR than in those with the normal aortic cusp, suggesting that hemodynamics might take part in the cause of Prol or AR. Twenty-two patients underwent VSD closure only, four valvuloplasty and one aortic valve replacement. Residual AR was occurred in three out of ten patients. After surgery, AR was disappeared in six out of seven patients with the first grade preoperative AR, but AR remained in all two patients with the second grade preoperative AR. Careful preoperative observation and early operation before the appearance of AR are the important factors for avoiding residual regurgitation after aortic valvuloplasty.
