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

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.

Supravalvular Aortic Stenosis with Aortic Regurgitation / 대한흉부외과학회지

Supravalvular aortic stenosis is an uncommon, congenital narrowing of the ascending aorta which originates just distal to the level of the ostium of the coronary artery. We conducted a successful surgical treatment in a 39 year- old female patient with a congenital supravalvular aortic stenosis and aortic regurgitation who did not show signs of William's syndrome. After we performed an inverted Y-shaped aortotomy toward the noncoronary sinus and right coronary sinus, pantaloon shaped prosthetic patch(Vascutek, Ino, USA) was used to repair the narrowing sinotubular junction. The aortic valve was replaced concommittently using Sorin Bicarbon 19mm. Her postoperative course was uneventful. The patient discharged at 9th postoperative day in good health.
