# Case Report: Parachute tricuspid valve in association with cyanotic congenital heart disease and juxtaposed atrial appendages in a 1-year-old boy—a rare anatomical association

## TL;DR

A 1-year-old boy had a rare heart condition involving a parachute tricuspid valve and other complex defects, highlighting the need for detailed anatomical evaluation.

## Contribution

This case report adds to the limited literature on the rare association of parachute tricuspid valve with cyanotic heart disease.

## Key findings

- The patient had a parachute tricuspid valve alongside cyanotic congenital heart disease.
- Echocardiography was crucial in diagnosing the complex anatomy and guiding palliation decisions.

## Abstract

Parachute tricuspid valve is an exceedingly rare congenital anomaly, often described in association with acyanotic heart defects. Its occurrence alongside cyanotic congenital heart disease is even less common. We report the case of a 1-year-old boy presenting with complex cyanotic heart disease along with parachute tricuspid valve. Detailed evaluation revealed a constellation of anomalies, including parachute tricuspid valve, double outlet right ventricle with D-malposed great arteries, severe pulmonary stenosis, and a non-routable ventricular septal defect. Echocardiography played a vital role in defining the complex anatomy and guided the decision toward single-ventricle palliation. This case underscores the importance of meticulous anatomical assessment in patients with congenital heart disease and contributes to the sparse literature on this rare condition.
