# A Case Report of a Baby Born to a Woman With Isolated Right Ventricular Apical Hypoplasia Without an Atrial Septal Defect

## TL;DR

A woman with a rare heart condition successfully gave birth to a healthy baby without complications.

## Contribution

First reported case of pregnancy in a woman with isolated right ventricular hypoplasia without an atrial septal defect.

## Key findings

- The patient's right ventricle was very small with no contractility.
- The right atrium was enlarged and supported pulmonary circulation without hypertension.
- The heart size increased after delivery compared to before pregnancy.

## Abstract

Pregnancy is a major life event for most women that causes extensive physiological changes. Hence, it is associated with additional risks in women with congenital heart disease. No reports of pregnancy or a baby born to a woman with isolated right ventricular hypoplasia without an atrial septal defect have been published. In this case, the patient’s right ventricle was very small with no contractility. The right atrium was highly enlarged, and its contractility resulted in pulmonary circulation without pulmonary hypertension. The size increased post-delivery than that before pregnancy. Fortunately, a healthy infant was born without any right heart failure symptoms.
