# Surgical treatment of the anomalous origin of the right pulmonary artery from the ascending aorta: report of two cases

## TL;DR

This paper reports two successful surgical corrections of a rare heart defect where the right pulmonary artery originates abnormally from the aorta, leading to heart failure in newborns.

## Contribution

The paper contributes two case reports of successful surgical correction for a rare congenital heart defect with favorable outcomes.

## Key findings

- Surgical correction via direct anastomosis resolved heart failure in both neonatal cases.
- Postoperative outcomes showed no anastomotic stenosis or pulmonary hypertension.
- Early diagnosis and timely intervention are critical for reducing mortality in this condition.

## Abstract

The anomalous origin of the right pulmonary artery is a rare congenital cardiac malformation that leads to early development of pulmonary vascular disease, heart failure, and death. Therefore, surgical correction should be performed as soon as the diagnosis is established. A high index of clinical suspicion and the use of non-invasive imaging studies play a crucial role in early diagnosis and timely intervention, thereby reducing the high mortality rates associated with this congenital heart disease. We present two cases of this rare entity, both with clinical manifestations of heart failure from the neonatal period. In both cases, surgical correction was performed through direct anastomosis of the right pulmonary artery to the main pulmonary artery. Both patients showed a favorable postoperative course, with no clinical or echocardiographic evidence of anastomotic stenosis or pulmonary hypertension.
