# Type F Quadricuspid Aortic Valve at Three-Dimensional Transoesophageal Echocardiography

## TL;DR

A 40-year-old man with a heart murmur was found to have a rare four-leaflet aortic valve using 3D heart imaging.

## Contribution

This case highlights the diagnostic value of three-dimensional transoesophageal echocardiography in identifying a rare quadricuspid aortic valve.

## Key findings

- A type F quadricuspid aortic valve was identified in an asymptomatic patient.
- Three-dimensional transoesophageal echocardiography confirmed the valve's structure.
- Transthoracic echocardiography had limited accuracy in quantifying aortic regurgitation.

## Abstract

We present the case of an asymptomatic 40-year-old male patient who underwent a transoesophageal echocardiography examination for further evaluation of aortic regurgitation. On physical examination, an occasional diastolic murmur was detected. Transthoracic echocardiography demonstrated aortic regurgitation that was difficult to quantify accurately. A type F quadricuspid aortic valve was subsequently identified and confirmed by three-dimensional transoesophageal echocardiography.
