Postoperative Evaluation for Ventricular Septal Defect Associated with Aortic Valvular Prolapse / 대한흉부외과학회지

ABSTRACT

BACKGROUND: From January 1989 to December 1996, we analyzed 22 cases of ventricular septal defect associated(VSD) with aortic valvular prolapse. MATERIAL AND METHOD: The mean age of the patients was 7 years with a range of 6 months to 22 years . Thirteen patients were male and 9 were female. The types of VSD were Kirklin type I in 13 , Kirklin type II in 8 and Kirklin type I+II in one. RESULT: The preoperative echocardiographic findings were aortic valvular prolapse in 10 patients, aortic valvular prolapse associated with aortic regurgitation in 6, and only aortic regurgitation in 2. Aortic valvular prolapse were found in operation field in 4 that was not be in preoperative echcardiography. Preoperative mean Qp/Qs, systolic PAP, systolic RVP were 1.48+/-0.42, 27.9+/-9.87, 32.9+/-10.87 mmHg, respectively. Twenty patients underwent patch closure of VSD, and two patients with moderate aortic regurgitation and prolapsed of the aortic valve underwent patch closure of VSD and aortic valvuloplasty. Short and long term echocardiographic follow-up in 8 patients who had preoperative aortic regurgitation were found to have improved or not aggravated by performing VSD patch closure only and patch closure with valvuloplasty in 2. Twelve patients who had only preoperative aortic valvular prolapse had no change in prolapsed valve in postoperative echocardiography. CONCLUSION: Early closure of VSD with patch is necessary in VSD with aortic valvular prolapse even in associated with mild regurgitation. But in moderate regurgitation, VSD closure with valvuloplasty is recommended.
