# Intramyocardial dissection of the left ventricle and post-myocardial infarction interventricular septal rupture. A clinical case

## TL;DR

An 86-year-old man with a rare heart condition involving a myocardial infarction and septal rupture underwent surgery but later died due to complications.

## Contribution

This paper reports a rare clinical case involving intramyocardial dissection and septal rupture following a myocardial infarction.

## Key findings

- The patient had a late anterior myocardial infarction without reperfusion.
- Intramyocardial dissection and interventricular septal rupture were diagnosed and surgically treated.
- The patient died from ventricular arrhythmia despite initial successful surgery.

## Abstract

Clinical case of an 86-year-old male patient presenting with a late anterior myocardial infarction without reperfusion is reported. Initial echocardiographic assessment revealed a rare and complex mechanical complication: intramyocardial dissection of the left ventricular apex associated with interventricular septal rupture. Given the severity of the condition, an urgent surgical intervention was undertaken using a bovine pericardial patch. Although the initial postoperative course was favourable, multiple subsequent complications ultimately led to the patient’s death from ventricular arrhythmia on day 50th of hospitalisation. This report underscores the importance of timely diagnosis and multidisciplinary management of this rare clinical entity.
