Giant left ventricle complicated with severe aortic regurgitation in Marfan patients with functional mitral regurgitation: A clinical study / 第二军医大学学报

ABSTRACT

Objective: To analyze the incidence of functional mitral regurgitation (FMR),post-operation characteristics and operation indications of Marfan patients with severe aortic regurgitation and giant left ventricle. Methods: The clinical data and the follow-up data of 19 Marfan patients with severe aortic regurgitation (≥10 ml) and giant left ventricle (LVEDd≥7.0 cm), who were treated from Jan. 2000 to Dec. 2007,were analyzed retrospectively. Results: All patients received Bentall operation and there was no perioperation death. Follow-up was 72 patient-year (ranging 3 months-7 years). The degree of FMR decreased obviously after operation, with an improvement rate of 87.5%, and the FMR almost disappeared 6 months to 1 year later. Conclusion: Bentall achieves good outcome in Marfan patients with severe aortic regurgitation and giant left ventricle. Mild to moderate FMR(< 10 ml) disappears with the decrease of the left ventricle size. For patients with severe FMR (≥ 10 ml) complicated with dysfunction of left ventricle, managed ventricular pacing is suggested.
