Treatment of ascending aorta disease with Bentall–De Bono operation using a mini-invasive approach

BACKGROUND: Use of minimally invasive approaches in cardiac surgery is increasing, obtaining a wide consensus and representing a challenging alternative technique for many surgeons. We report our experience of the treatment of ascending aorta disease using the Bentall-De Bono procedure through a minimally invasive approach. METHODS: Between September 1997 and June 2005 at 'Policlinico San Matteo', Pavia, we treated 40 patients affected by ascending aorta disease and aortic valve regurgitation using a Bentall-De Bono procedure through a minimally invasive approach, by means of a reversed T or J ministernotomy. Data were analyzed retrospectively. Thirty patients were men. Short-term and mid-term mortality and peroperative complications were analyzed. RESULTS: None of the patients died during the 30-day postoperative period. The mean ICU and length of stay times were 3.3 +/- 8.2 and 9.3 +/- 7.2 days, respectively. Six patients (15%) had one or more postoperative complications. One patient (2.5%) underwent early reoperation for bleeding. None underwent a procedure-related reoperation. Mechanical ventilation was longer than 48 h in five patients (12.5%). The mean follow-up was 38.4 +/- 31 months. Survival at 1, 3 and 5 years was, respectively, 94.1, 90.6 and 90.6%. At the end of the follow-up, there were 37 survivors. Twenty-seven (73%) patients were in New York Heart Association I, six (16%) were in New York Heart Association II and four (11%) were in New York Heart Association III. CONCLUSION: Reversed T or J ministernotomy is a feasible and secure alternative to complete sternotomy. The short incision may enhance the outcome and does not affect the survival, offering proper access to the anatomic structures.
