# Hypoplastic Posterior Leaflet of the Tricuspid Valve—a Unique Cause of Right Heart Failure

## TL;DR

This paper discusses a rare congenital heart condition causing right heart failure and highlights the importance of advanced imaging for diagnosis.

## Contribution

The paper identifies hypoplastic posterior leaflet of the tricuspid valve as a unique and rare cause of primary tricuspid regurgitation.

## Key findings

- Primary tricuspid regurgitation can result from congenital hypoplasia of the leaflets.
- Multimodality imaging is essential for diagnosing the underlying cause of tricuspid regurgitation.

## Abstract

•TR can be due to either primary or secondary causes.•Primary TR due to congenital hypoplasia of leaflets is rare.•Multimodality imaging is key in identifying the cause of TR.

TR can be due to either primary or secondary causes.

Primary TR due to congenital hypoplasia of leaflets is rare.

Multimodality imaging is key in identifying the cause of TR.
