Right ventricular pseudoaneurysm (RVP) is rare but can be lethal if left untreated. Here we describe a case of an 88-year-old woman with radiofrequency catheter ablation (RFCA)-associated iatrogenic RVP presenting with refractory paroxysmal supraventricular tachycardia. We performed an electrophysiological study, which led to a final diagnosis of atrioventricular nodal reentrant tachycardia, for which successful RFCA was performed. On postprocedural day 2, echocardiography revealed a small right ventricular apical outpouching, far from the RFCA target site without signs and symptoms. Cardiac computed tomography angiography led to the correct diagnosis of RVP, which was successfully treated with surgical repair. The postoperative course was uneventful. This case highlights the importance of the potential risk of iatrogenic RVP and the value of cardiac computed tomography angiography in diagnosing RVP in patients with right ventricular outpouching.
