Abstract

Background: Premature ventricular complexes (PVCs) originating in the ventricular outflow tracts are mostly of benign character.

Case summary: We describe a rare case of pulmonary hypertension with severe hypoxaemia and confusion caused by a significant mitral regurgitation (MR) during PVC originating in the left ventricle summit. After successful PVC ablation, all above-mentioned clinical parameters had normalized.

Discussion: Premature ventricular complexes originating in the outflow tracts should be considered as a potential though rare cause of severe MR and pulmonary hypertension.
