“…Left ventricle pseudoaneurysm is a very rare complication of catheter ablation for ventricular arrhythmias that occurs regardless of the presence or absence of structural heart disease ( 4 , 5 ). It is a form of cardiac rupture concealed by the adherent pericardium or scar tissue and has a wide range of clinical manifestations ( 6 ).…”

A 74-year-old woman presented with incessant wide complex tachycardia that was refractory to cardioversions. Successful radiofrequency catheter ablation was performed on the left ventricular posteromedial papillary muscle. An inaudible steam pop has occurred during the procedure, but we confirmed that there were no complications during the procedure and short-term follow-up of echocardiography. Two months after the procedure, an asymptomatic pseudoaneurysm was identified at the ablation site that had not been observed in the short-term follow-up.

“…Only two cases involving early complications have been reported. Dandamudi [10] described a 2.4- × 2.4-cm left ventricular pseudoaneurysm following premature ventricular contraction ablation of the endocardial portion of the left ventricular summit, and Gill [11] described a small pseudoaneurysm after radiofrequency ablation of supraventricular tachycardia. Three cases involving late complications have also been reported.…”

Background Radiofrequency catheter ablation is approved effective therapy for premature ventricular contraction. However, the rare but serious complication such as pseudoaneurysm should be given more attention. It is life-threatening due to the high risk of rupture. Only few cases have been reported in the literature. We herein report a huge acute left ventricular pseudoaneurysm after catheter ablation therapy. Case presentation A 69-year-old man underwent radiofrequency catheter ablation for premature ventricular contraction at a local hospital. The patient developed shock the second day after ablation. A chest computed tomography (CT) scan showed pericardial effusion. Pericardiocentesis was performed, and the puncture fluid was a bloody pericardial effusion. The transthoracic echocardiogram revealed an 9- × 4-cm giant pseudoaneurysm with a cystic structure in the left ventricular inferior wall near the mitral annulus along the left atrium. The pseudoaneurysm was connected to the left ventricular cavity through a 8-mm neck, and the lumen was filled with systolic and diastolic blood flow. The patient underwent three-dimensional transesophageal echocardiography. The pseudoaneurysm and the tract was clearly visible. Emergency surgery was performed to resect the pseudoaneurysm. A bovine pericardial patch was placed on the neck of the pseudoaneurysm. Echocardiographic examination confirmed the absence of cardiac lesions after the operation. Conclusions It is rare to see such a large pseudoaneurysm after radiofrequency catheter ablation. Clinicians should be allert to the potential risks to patients in the process of an effective treatment. Echocardiography plays an important role in the prompt diagnosis and prognosis of this disease. Emergency surgery is a better method for treatment of huge pseudoaneurysm.

“…Moreover, cardiac rupture or cardiac tamponade after RFCA is usually healed after acute management, and surgical treatment is not usually required. Gill and colleagues 11 reported spontaneous regression of submitral pseudoaneurysm after mapping during an electrophysiology study. Therefore, careful follow-up may be other option for managing patients with LV pseudoaneurysms with a small risk of rupture after RFCA.…”
