Abstract:

BACKGROUND: Annulus calcification and paravalvular cysts often appear during aortic valve replacement. At this time, special techniques are generally used to assist the aortic valve replacement.
OBJECTIVE: To investigate the clinical feasibility of pericardium patch repaired aortic annulus to assist aortic valve replacement for the treatment of calcific aortic stenosis complicated by annulus calcification.
METHODS: Forty two patients with calcific aortic stenosis complicated by annulus calcification were selected from the First Affiliated Hospital of Zhengzhou University during January 2009 and January 2012. Their clinical data were retrospectively analyzed. The effective orifice area index of aortic valve, maximum transvalvular pressure gradient, peak blood flow velocity and left ventricular ejection fraction were analyzed with statistical software before and after pericardium patch repaired aortic annulus assisted aortic valve replacement, and then the effect of autologous pericardium patch repaired aortic annulus to assist aortic valve replacement was analyzed.
RESULTS AND CONLUSION: There was no intraoperative death during the pericardium patch repaired aortic annulus assisted aortic valve replacement. The intraoperative aortic clamping time was 52-88 (63.0±18.1) minutes, and the cardiopulmonary bypass time was 78-122 (102.6±25.1) minutes. One patient appeared acute renal failure after replacement, and cured after the bedside hemodialysis treatment. The rest patients had no serious complications. The length of hospital stay was 7-20 (13.6±5.5) days. The postoperative Doppler echocardiography showed the heart valve prosthesis was good, and no paravalvular leaks were found. The orifice area index of aortic valve, maximum transvalvular pressure gradient, peak blood flow velocity and left ventricular ejection fraction were significantly improved at 6 months after replacement, and the differences were significant when compared with those before replacement (P < 0.05). In patients with appropriate surgical indications, the autologous pericardium patch repaired aortic annulus assisted aortic valve replacement surgery can achieve satisfactory effects, and the operation is safe and simple, which is considered as a practicable technology.
