# Case report of pulmonary vein isolation in situs inversus totalis

## TL;DR

This case report describes a successful treatment of atrial fibrillation through pulmonary vein isolation in a patient with a rare condition called situs inversus totalis.

## Contribution

The novelty lies in demonstrating the successful execution of pulmonary vein isolation in a patient with situs inversus totalis.

## Key findings

- Pulmonary vein isolation was successfully performed in a patient with situs inversus totalis.
- The patient showed no recurrence of atrial fibrillation for two years post-procedure.

## Abstract

Situs inversus totalis (SIT) is a rare condition, where all the organs in the body are mirrored. Atrial fibrillation occurs in patients with SIT. We describe the case of pulmonary vein isolation (PVI) in SIT.

A patient with atrial fibrillation was referred to our hospital due to palpitations. Diagnosis of atrial fibrillation was made by electrocardiogram. The patient reported to have a SIT that was confirmed. Meticulous preparation was done including a three-dimensional model and radiofrequency PVI was performed successfully. No recurrence of atrial fibrillation was detected until last follow-up 2 years after PVI.

Pulmonary vein isolation in SIT can be performed successfully and with excellent long-term result.
