Objective To summarize the clinical experiences of using selfpericardial patch heightening to treat aortic valve prolapse. Methods From May 2000 to July 2007, seventeen patients with aortic valve prolapse were treated by selfpericardial patch heightening. Fifteen cases had right coronary cusp prolapse, one had left coronary cusp prolapse, and one had no coronary cusp proplapse. There were 10 cases with moderate aortic regurgitation and 7 with severe regurgitation. Autologous pericardium was continuously sutured on the proplapsed cusp by 5-0 or 6-0 Prolene suture. The transesophageal echocardiography(TEE) showed that there was few or mild aortic regurgitation during operation. Preoperative and postoperative echocardiography results were compared. Results The comparison between preoperative and postoperative echocardiography results showed that postoperative left ventricular enddiastolic diameter reduced obviously(38.3±9.6 mm vs. 47.2±10.3 mm，P=0.013)；postoperative aortic valve systolic pressure difference reduced（9.8±5.6 mm Hg vs. 10.3±5.3 mm Hg，P=0.792）; postoperative aortic valve diastolic pressure difference reduced obviously(45.7±13.6 mm Hg vs. 78.4±19.9 mm Hg，P= 0.000). Echocardiographic examination before discharge showed that 4 cases had no obvious aortic regurgitation, 9 had mild aortic regurgitation and 4 had moderate aortic regurgitation. The average followup time was 32 months(4.74 months). One case underwent aortic valve replacement because of severe aortic regurgitation 4 months later after the operation, and the rest needed no second operation. Conclusion Using selfpericardial patch heightening to treat aortic valve prolapse is a simple operative method, and it is good for young patients or small aortic annulus.
