Summary

This study reports a rare case of ventricular septal dissection, a condition where the interventricular septum tears, complicating acute myocardial infarction. This unique case involved no perforation, offering new insights into cardiac emergencies.

Background:

Acute myocardial infarction (AMI) can lead to various cardiac complications.
Ventricular septal defects (VSDs) are known, but septal dissection is exceptionally rare.

Observation:

A 79-year-old male presented with acute inferior myocardial infarction and a gastric ulcer.
Echocardiography revealed an echo-free space in the posteroinferior interventricular septum.
Chest CT and left ventriculography confirmed a dissecting aneurysm within the septum, communicating with the left ventricle only.

Findings:

The case describes the first instance of ventricular septal dissection without associated ventricular septal perforation.
Imaging modalities successfully visualized the dissecting space and its unique communication pathway.

Implications:

This case expands the spectrum of rare cardiac complications following myocardial infarction.
Understanding septal dissection is crucial for accurate diagnosis and management of complex cardiac events.
Further research may elucidate the specific mechanisms and long-term outcomes of this rare condition.
