# Recent and speculative remote myocardial trauma: a case series

## TL;DR

This case series explores the challenges of diagnosing remote myocardial trauma and suggests it may be more common than previously believed.

## Contribution

The study highlights the under-recognized prevalence of remote myocardial trauma through a series of clinical cases.

## Key findings

- Remote myocardial trauma can lead to adverse remodelling and heart failure.
- Imaging challenges arise due to long-term changes obscuring initial trauma signs.
- The case series suggests remote myocardial trauma is more prevalent in clinical practice.

## Abstract

Cardiac blunt trauma clinically presents as a spectrum of injuries of varying severity. However, the diagnosis of complications of remote myocardial trauma is often challenging, especially if the patient forgets to mention a remote history of chest trauma.

In this study, we present a patient who recently experienced traumatic myocardial dissection and interventricular septal rupture, alongside three patients exhibiting a mimic double-chambered left ventricle, indicative of prior remote myocardial trauma potentially associated with myocardial dissecting tear.

Patients with recent severe myocardial injury are detectable through cardiac imaging. However, forgotten remote myocardial trauma can lead to adverse myocardial remodelling, heart failure, and arrhythmias. Long-term myocardial remodelling can obscure initial myocardial imaging characteristics, posing challenges in interpretation. Our case series suggests that remote myocardial trauma may be more prevalent than commonly thought of in clinical practice.
