Key result
Ventricular pacing can induce hemodynamically significant mitral valve regurgitation in the presence of normally timed end-diastolic atrial contraction.
Case Report (n=1)
Ventricular pacing can be an unusual etiology for sudden, hemodynamically significant mitral valve regurgitation during cardiac operations.
Ventricular pacing warrants consideration in unexplained intraoperative mitral regurgitation; leaves open its prevalence and management implications.
Mitral valve regurgitation (MR) may develop or worsen suddenly during cardiac operations and result in severe arterial hypotension. Among the common causes are annular dilatation due to left ventricular distention and ischemic papillary muscle dysfunction. The incident reported here highlights an unusual etiology not previously described in a clinical setting ― ventricular-pacing-induced MR in the presence of normally timed end-diastolic atrial contraction

Mark et al. (1991) conducted a case report in Mitral valve regurgitation during cardiac operations (n=1). Ventricular pacing was evaluated on Mitral valve regurgitation. Ventricular pacing can induce hemodynamically significant mitral valve regurgitation in the presence of normally timed end-diastolic atrial contraction.
