  • Article: Should aortic valve reimplantation be offered to patients with a large aorto-ventricular junction?
    [show abstract] [hide abstract]
    ABSTRACT: OBJECTIVES: Large aortic root aneurysms might increase leaflet stress and compromise aortic valve durability after the reimplantation technique. We analysed the impact of the preoperative aorto-ventricular junction (AVJ) diameter on the durability of the valve. METHODS: Between March 2004 and January 2012, 150 patients underwent the David operation on the aortic root. We identified 47 patients with a preoperative AVJ >28 mm (Group A) and 103 patients with a diameter ≤28 mm (Group B). The mean follow-up was 44 ± 27 months. Both groups were compared regarding mortality, freedom from moderate or severe aortic valve regurgitation and freedom from reoperation. RESULTS: Early mortality was 1.3%. Actuarial survival at 1, 3 and 5 years was 97 ± 2, 94 ± 3 and 94 ± 3% for Group A, and 99 ± 1, 97 ± 1 and 94 ± 3% for Group B, respectively (P = 0.3). Two patients in Group B were reoperated for severe aortic regurgitation (AR). Actuarial freedom from reoperation at 1, 3 and 5 years was 100% for Group A, and 98 ± 1, 98 ± 1 and 96 ± 2% for Group B, respectively (P = 0.3). During the follow-up, 6 patients (3 in each group) developed AR ≥Grade II. Therefore, actuarial freedom from AR grade II or greater at 1.3 and 5 years was 97 ± 2, 94 ± 4 and 87 ± 7% for Group A, and 99 ± 1, 97 ± 1 and 95 ± 2% for Group B (P = 0.3). CONCLUSIONS: The reimplantation technique shows excellent results. Medium-term stability of the aortic valve repair was not influenced by the preoperative aorto-ventricular junction diameter.

  • Article: Aortic valve-sparing in 37 patients with Marfan syndrome: midterm results with David operation.
    [show abstract] [hide abstract]
    ABSTRACT: We reviewed our experience with aortic valve-sparing operations in Marfan syndrome during last 5 years. Between March 2004 and June 2009, 94 patients with aortic root aneurysms underwent valve-sparing operations. Of these, 37 (68% male) were diagnosed with Marfan syndrome, according to the Ghent diagnostic criteria. Mean age was 30 +/- 10 years (range, 11 to 59 years). Moderate/severe aortic regurgitation was present in 13%, and the mean diameter of the Valsalva sinuses was 50 +/- 4 mm (range, 42 to 62 mm). The David V modification was performed in the last 28 patients. Additional procedures were mitral valve repair in 6, tricuspid valve repair in 3, closure of septal atrial defect in 2, and closure of a patent foramen ovale in 13. Mean follow-up was 27 +/- 16 months (range, 1 to 61 months). There were no in-hospital deaths and no major adverse outcomes. One patient required implantation of a mechanical prosthesis during the same procedure because of moderate aortic regurgitation. One late death occurred. No patients required reoperation. In the last follow-up, 23 patients did not have aortic regurgitation, 12 had grade I, and 1 had grade II. No thromboembolic complications have been documented, and 97% of the patients are free from anticoagulation. Short-term and midterm results with the reimplantation technique for aortic root aneurysms in Marfan patients are excellent. If long-term results are similar, this technique could be the treatment of choice for these patients.
