Key result
Surgical correction of severe functional mitral regurgitation in dilated cardiomyopathy provides symptomatic benefit and reverse ventricular remodeling, though its survival benefit over medical therapy remains controversial.
Why the study?
Does mitral valve surgery improve outcomes in patients with functional mitral regurgitation secondary to dilated cardiomyopathy?
Does mitral valve surgery improve outcomes in patients with functional mitral regurgitation secondary to dilated cardiomyopathy?
Surgical correction of severe functional mitral regurgitation in dilated cardiomyopathy is warranted for symptomatic relief and reverse remodeling, though the optimal choice between repair and replacement requires further randomized trials.
No takes yet. Share an insight, caveat, or question.
Surgery may be considered for symptomatic relief in severe functional MR with DCM; leaves survival benefit over medical therapy open, warranting RCTs.
Nicolini et al. (2013) conducted a review in Functional mitral regurgitation secondary to dilated cardiomyopathy. Surgical treatment (mitral valve repair or replacement) vs. Medical therapy or CABG alone was evaluated. Surgical correction of severe functional mitral regurgitation in dilated cardiomyopathy provides symptomatic benefit and reverse ventricular remodeling, though its survival benefit over medical therapy remains controversial.
