Preoperative LV dysfunction or dilatation was associated with markedly lower 10-year survival after repair; leaves open whether earlier intervention prevents these complications in asymptomatic severe MR.
Does the presence of preoperative complications affect long-term survival in asymptomatic patients with severe degenerative mitral regurgitation undergoing mitral valve repair?
Mitral valve repair in asymptomatic severe degenerative MR yields excellent long-term survival, but preoperative complications like LV dysfunction significantly attenuate these benefits, supporting early surgical intervention.
