[Does aortic cusp repair influence the outcome of valve sparing aortic root replacement?].
BACKGROUND
Outcome of the patients who underwent aortic root replacement with valve sparing procedure concomitant with cusp repair was evaluated.


METHODS
Between October 1999 and April 2009, valve sparing aortic root replacement were performed in 62 patients. Isolated valve sparing procedure was performed in 38 patients (control) and concomitant cusp repair was performed in 24 patients (aortic valve plasty: AVP). Cusp prolapse was corrected by plication of Arantius body (n = 13), cusp perforations were closed by pericardial patch (n = 6) or reinforcement of free margin (n = 6).


RESULTS
No patient died during the hospital stay and no thromboembolic events occurred in the follow up. Pre-operative grade of aortic insufficiency was 3.0 +/- 0.9 in AVP group vs. 2.5 +/- 1.3 in control (NS). There was no significant difference between both groups regarding age, cardiac function and preoperative aortic root diameter. However, eccentric jet by preoperative transesophageal echocardiography (TEE) was more often in group AVP than in control (p<0.01). Five patients underwent reoperation because of recurrent aortic regurgitation (AR) or hemolysis. Postoperative AR grade were similar in both groups (0.9 +/- 0.5 vs 0.5 +/- 0.6). During follow up, the 5 year freedom from re-operation (aortic valve replacement: AVR) was 85.1+/- 8.2% in AVP and 94.0 +/- 4.1% in control (NS). 5-year-survival was 100% and 95.0 +/- 4.9% (NS), respectively.


CONCLUSIONS
Valve sparing aortic root replacement with concomitant cusp repair provided satisfactory midterm result.
