# Right-sided Cardiac Resynchronization Therapy via Left Bundle Branch Area Pacing in a Patient with Persistent Left Superior Vena Cava

## TL;DR

This paper describes a successful case of right-sided cardiac resynchronization therapy in a patient with a rare heart condition using a specific pacing technique.

## Contribution

The paper presents a novel approach to CRT implantation in patients with persistent left superior vena cava.

## Key findings

- Right-sided CRT via LBBAP is feasible in patients with PLSVC.
- The procedure was successfully performed in a patient with this rare anatomical condition.

## Abstract

Cardiac resynchronization therapy (CRT) via left bundle branch area pacing (LBBAP) has emerged as effective and safe as conventional CRT. Left-sided CRT implantation in patients with persistent left superior vena cava (PLSVC) is challenging and impossible in some patients. Right-sided CRT implantation, either conventional or LBBAP, is also tricky, as the delivery sheaths are feasible for left-sided implantations. Here, we present a patient with PLSVC who underwent successful right-sided CRT implantation via LBBAP.
