# Usefulness of the ripple map and late annotation mapping to visualize an activation pattern within Koch's triangle in a patient with persistent left superior vena cava

## TL;DR

This paper shows how new mapping techniques help treat heart rhythm issues in patients with a rare vein structure.

## Contribution

A novel use of Ripple and LAM modules for ablation targeting in patients with persistent left superior vena cava.

## Key findings

- High-resolution mapping identified slow pathway ablation targets in a PLSVC patient.
- The approach overcame anatomical challenges in AVNRT treatment.
- It offers a more effective strategy for complex cases.

## Abstract

High‐resolution mapping with Ripple and LAM modules enabled precise identification of slow pathway ablation targets in a PLSVC patient. This novel approach overcame anatomical challenges, offering a more effective strategy for AVNRT treatment in complex cases.
