Submitral aneurysm communicating with coronary sinus in a child

Area of Science:

• Cardiology
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• Abnormal pulmonary venous return can present in various forms.
• Accessory cardiac chambers are rare congenital heart anomalies.
• Submitral aneurysms pose diagnostic and therapeutic challenges.

Purpose of the Study:

• To describe a case of a large submitral aneurysm presenting as abnormal pulmonary venous return.
• To illustrate the diagnostic findings of this rare condition.
• To report the long-term outcome and percutaneous management.

Main Methods:

• Echocardiography was used for initial diagnosis.
• Serial cardiac imaging was performed over 10 years.
• Percutaneous closure of the abnormal orifice was performed.

Main Results:

• A large accessory cardiac chamber originating from the left ventricle was identified.
• This chamber connected to the left ventricle and the right atrium via the coronary sinus.
• Percutaneous closure of the submitral aneurysm's orifice was technically successful.

Conclusions:

• Submitral aneurysm is a rare cause of cardiac chamber abnormalities.
• Echocardiography is crucial for diagnosing such anomalies.
• Percutaneous intervention offers a viable treatment option for selected cases.
