# Left Ventricular Rupture Due to Congenital Partial Defect of the Left Ventricular Free Wall

## TL;DR

A newborn had left ventricular rupture after heart surgery due to an undetected congenital defect, highlighting a rare but serious risk in certain cardiac conditions.

## Contribution

This case report identifies a rare cause of left ventricular rupture after neonatal cardiac surgery.

## Key findings

- LV rupture was caused by a congenital partial defect of the LV free wall.
- The defect was successfully repaired using double-patch closure with BioGlue.
- The case emphasizes the risk of LV rupture in underfilled left ventricles after TAPVC surgery.

## Abstract

A neonate who underwent corrective surgery for cardiac-type total anomalous pulmonary venous connection (TAPVC) was suspected of having a pseudoaneurysm of the left ventricular (LV) free wall on transthoracic echocardiography (TTE) on postoperative day 11. Emergency surgery was performed the following day, revealing LV rupture due to a congenital partial defect of the LV free wall. The defect was successfully repaired using double-patch closure reinforced with BioGlue. The postoperative course was uneventful. This case highlights that left ventricular rupture may occur due to an unrecognized congenital defect after neonatal cardiac surgery, particularly in conditions such as TAPVC, where the left ventricle is underfilled preoperatively.

LV free wall rupture is a known but fatal complication following cardiac surgery.
