# Anatomic reconstruction of isolated left main coronary artery ostial stenosis using a right internal mammary artery patch

## TL;DR

This paper describes a surgical technique using a mammary artery patch to treat a specific type of coronary artery blockage.

## Contribution

The novel use of a right internal mammary artery patch for left main coronary artery ostial stenosis is presented.

## Key findings

- An arterial patch from the right internal mammary artery successfully restored patency in a left main coronary artery stenosis.
- This technique may improve myocardial perfusion and mimic normal vascular anatomy better than traditional bypass grafting.

## Abstract

Surgical patch angioplasty is an alternative to classic coronary artery bypass grafting for patients with isolated coronary ostial stenosis and normal distal coronary arteries. We present a case where we successfully used an arterial patch from the right internal mammary artery to restore patency of an isolated ostial left main coronary artery stenosis. This technique is likely to offer more physiological antegrade myocardial perfusion, mimic normal vascular anatomy, and may be associated with an improved outcome.
