Introduction: Premature ventricular complex (PVC) is the most common cardiac arrhythmia, which in some circumstances can lead to syncope, arrhythmia-induced cardiomyopathy and sudden death. In idiopathic PVCs, the first choice of treatment is radio-frequency ablation. Identification of the substrate location makes it possible to determine the ablation site, leading to an increased success rate. Complications are related mainly to the ablation technique, peri-procedural anticoagulation therapy, and the access site. Pericardial tamponade is a rare complication. A case in which the ablation procedure of idiopathic PVCs, complicated by cardiac tamponade, is presented in this paper.Case presentation: A 56-year-old female presented with symptomatic premature ventricular contractions. She had frequent palpitations, dyspnea, and exercise intolerance for ten years.
