Co-occurrence of late potential and discrete prepotential on ablation site in a case of cardiac crux located premature ventricular complexes successfully ablated within the middle cardiac vein

J Arrhythm. 2019 May 15;35(3):550-553. doi: 10.1002/joa3.12190. eCollection 2019 Jun.


Some premature ventricular complexes (PVCs) originate from the coronary venous system. The great cardiac vein and the anterior cardiac vein are the most frequent localizations. The middle cardiac vein is an unusual anatomy for a point of origin for PVC. We present here a case of frequent PVCs with characteristic electrocardiographic features, which we successfully ablated inside the middle cardiac vein.

Keywords: cardiac crux; discrete prepotential; late potential; middle cardiac vein; premature ventricular complex.
