Post-infarction left ventricle to right atrium fistula diagnosed by transthoracic Doppler echocardiography

Area of Science:

• Cardiology
• Cardiac Surgery
• Medical Imaging

Background:

• Myocardial infarction (MI) can lead to serious cardiac complications.
• Left ventricular aneurysms are a known, albeit uncommon, sequela of MI.
• Intracardiac shunts can arise from complex cardiac events.

Observation:

• A 63-year-old male patient experienced an inferior wall myocardial infarction.
• The patient subsequently developed a left ventricular aneurysm with an unusual communication to the right atrium.
• This communication resulted in a haemodynamically significant intracardiac shunt.

Findings:

• Transthoracic Doppler echocardiography proved effective in diagnosing this rare complication.
• The diagnostic accuracy of echocardiography was crucial for subsequent management.
• Successful surgical repair was performed to address the aneurysm and shunt.

Implications:

• This case highlights the importance of considering rare complications following myocardial infarction.
• Doppler echocardiography is a vital tool for diagnosing complex intracardiac abnormalities.
• Timely diagnosis and surgical intervention can lead to positive patient outcomes in complex cardiac cases.
