  • Title: [Evaluation of aortic valve replacement involving small severely calcified aortic annulus in elderly patients].

    Journal: Kyobu Geka; 2006 Apr; 59(4):336-9. PubMed ID: 16613154.
    Abstract:
    We performed aortic valve replacement in 24 patients aged over 70 with small calcified valves. The surgical management of such patients remains controversial as the extensive calcification compromises implantation. Hence, we used an ultrasonic debridement instrument to remove calcium and selected a small prosthesis with the largest possible orifice without enlargement of the aortic annulus. Echocardiography showed significant reductions in left ventricular mass index compared with preoperative values. Early and mid-term prognosis has been relatively good.
