Radiofrequency Pulmonary Vein Isolation in a Patient with Dextrocardia With Situs Inversus Totalis.

Abstract

BACKGROUND: We present a case report of a 67-year-old male with dextrocardia situs inversus totalis and persistent atrial fibrillation who presented for radiofrequency pulmonary vein isolation. METHODS: Pulmonary vein isolation was performed using the St Jude Medical Ensite NavX 3D mapping system with AccuNav ICE guidance. RESULTS: All pulmonary veins were successfully isolated. The procedure time was 125 mins with a fluoroscopy time of 44.3 mins. The fluoro dose was 2095cGycm2. There were no procedural complications. CONCLUSIONS: Radiofrequency pulmonary vein isolation can be performed safely and successfully in patients with dextrocardia and situs inversus totalis.

Main findings

In this single patient, all pulmonary veins were successfully isolated using a 3D mapping system with intracardiac echocardiography guidance. Procedure time was 125 minutes, fluoroscopy time 44.3 minutes, fluoroscopy dose 2095 cGycm2, and no procedural complications were reported.

Outcomes measured

• Procedural success (pulmonary vein isolation)
• Procedure time
• Fluoroscopy time
• Fluoroscopy dose
• Procedural complications

Limitations

• Single-patient case report
• No RF exposure parameters (e.g., frequency, power, SAR) reported
• No follow-up outcomes reported in the abstract
