Abstract
We describe a patient with hemodynamic deterioration and worsening mitral regurgitation related to right ventricular apex pacing. Time-dependent changes in papillary muscle contraction as well as ventricular remodeling by right ventricular apex pacing might be responsible for this rare but serious complication.
