Isolated Closure versus Mitral Valvuloplasty for Patent Ductus Arteriosus in Patients with Mitral Regurgitation: A Single-Center, Retrospective Study
: Background: Patent ductus arteriosus (PDA) can cause left-heart volume overload and functional mitral regurgitation (MR), although some patients have structural mitral abnormalities requiring repair. We compared MR and cardiac remodeling after isolated PDA closure and PDA closure combined with mitral valvuloplasty (M...
