[Reoperations for complications after mechanical valve replacement].
Among 310 patients with mechanical valve replacement, 24 patients required reoperations for three types of complications; 12 disc immobilizations on 10 patients, 9 prosthetic valve endocarditis (PVE) on 8 patients and 8 perivalvular leakage or aortic pseudoaneurysm on 7 patients. Long-term survival was 71 percent for PVE and leakage, and 20 percent for emergency surgery of disc immobilization with mean follow up of 67 months. We suggest a few compromised patients with healed fungal endocarditis might show various types of prosthetic valve complications such as tissue ingrowth, late perivalvular leakage or pseudoaneurysmal formation.
