# Quadricuspid Aortic Valve With Severe Aortic Regurgitation

## TL;DR

This paper discusses how quadricuspid aortic valves, once only detectable during surgery, can now be identified preoperatively using advanced imaging techniques.

## Contribution

The paper highlights the role of modern imaging in preoperative detection and management of quadricuspid aortic valves.

## Key findings

- Quadricuspid aortic valves can now be detected preoperatively using transthoracic echocardiography.
- Further imaging with transesophageal echocardiography or CT can guide surgical strategies.

## Abstract

Whenever a quadricuspid aortic valve (QAV) was present, it was historically only identified during open heart surgery. However, recent advances in transthoracic echocardiography have made it possible to detect QAV preoperatively. Further evaluation using transesophageal echocardiography or computed tomography before open surgery may help guide the surgical treatment strategy.
