| Summary: | Six patients in our clinical program who were diagnosed with high burden (>10%) premature ventricular contractions (PVCs) and concomitant significant upper GI disease with no other significant cardiac history demonstrated a significant reduction in the burden of PVCs following surgical or procedural interventions of the upper GI tract (68.34% reduction, <i>p =</i> 0.024). Furthermore, in all cases, the origin of the PVCs was from the base of the right ventricular outflow tract (RVOT). This is the first report in the literature that we are aware of that makes the unique association that we propose a dual mechanism of action of the upper GI and vagally mediated PVCs and through direct, anatomical extrinsic triggering of the right ventricular outflow tract (RVOT) of the heart. These are very preliminary findings that warrant larger clinical and mechanistic studies that if confirmed, may define a new physiologic subset of PVCs for which we propose a new term, “E-PVCs”. |
