# Aortic Regurgitation After Right Coronary Cusp Injury During Percutaneous Coronary Intervention

## TL;DR

A patient who had a rare heart valve injury during a heart procedure later required valve replacement due to severe leakage.

## Contribution

Highlights a rare complication of coronary angiography leading to severe aortic regurgitation requiring valve replacement.

## Key findings

- Injury to a coronary cusp during coronary angiography can lead to severe aortic regurgitation.
- Symptoms may not appear immediately, as seen in the asymptomatic patient who later required aortic valve replacement.

## Abstract

Injury of a coronary cusp of the aortic valve is a rare complication that can occur during coronary angiography. It usually occurs from multiple attempts with different catheters to access the ostia of the right coronary artery, but it has also occurred accessing the ostia of the left coronary artery. We present the case of a patient who underwent coronary angiography with suspected coronary cusp injury that remained asymptomatic but was found to have severe aortic regurgitation during coronary artery bypass graft surgery (CABG) one week later, requiring an aortic valve replacement.
