Amplatzer device closure of a tortuous Gerbode (left ventricle-to-right atrium) defect complicated by transient...

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Gerbode defect is a rare congenital or acquired intracardiac communication between the left ventricle and the right atrium.
• Acquired Gerbode defects can occur secondary to endocarditis, trauma, or cardiac surgery, often presenting with symptoms of heart failure or pulmonary hypertension.

Observation:

• An 86-year-old male with a history of mitral valve surgery presented with progressive dyspnea and a cardiac murmur.
• Echocardiography identified a significant left ventricular-to-right atrial communication, consistent with a Gerbode defect.

Findings:

• The Gerbode defect was successfully closed percutaneously using an Amplatzer Septal Occluder.
• The patient experienced transient postoperative hemolysis and renal dysfunction, which resolved spontaneously.
• One-year follow-up demonstrated no residual shunt on echocardiography and significant improvement in the patient's exercise tolerance.

Implications:

• Percutaneous closure is a viable and effective alternative to surgical repair for Gerbode defects, particularly in elderly or high-risk patients.
• Minimally invasive techniques can lead to improved patient outcomes and reduced recovery times.
• This case highlights the importance of echocardiography in diagnosing complex intracardiac shunts and the efficacy of device closure for acquired Gerbode defects.
