Why the study?
Does left ventricular pacing improve severe mitral regurgitation and refractory heart failure in a patient with right ventricular pacing-induced dyssynchrony?

Left ventricular pacing can resolve severe mitral regurgitation and refractory heart failure induced by right ventricular pacing.
Potential rescue option in RV pacing-induced severe MR/HF; leaves open confirmation in prospective trials.
A case of severe mitral regurgitation with refractory heart failure, after atrioventricular junction ablation and pacemaker implant, was solved with left ventricular pacing. Mitral regurgitation was related to a change in segmental left ventricular motion during right ventricular pacing.
