Abstract:

Premature Ventricular Contractions (PVC) is a frequent finding in the general population, especially in patients with structural cardiac disease. Nonetheless, data regarding aortomitral continuity as substrate for PVC in normal hearts is still limited. We present 3 cases of young patients without structural heart disease, with frequent symptomatic PVC, without clinical improvement after antiarrhythmic drugs treatment. All patients were submitted to an electrophysiological study that identified the aortomitral continuity as the earliest site of PVC activation. After a successful ablation, all the patients improved their clinical status. These cases and literature review of the aortomitral continuity substrate highlight the indications, efficacy, safety and limitations of catheter ablation.
