Anomalous right ventricular muscle bundle. Repair through the right atrium

Area of Science:

• Cardiology
• Cardiac Surgery
• Pediatric Cardiology

Background:

• Anomalous muscle bundles in the right ventricle can lead to outflow tract obstruction.
• This anomaly is frequently associated with ventricular septal defects.
• Traditional surgical correction often involves a right ventriculotomy.

Purpose of the Study:

• To evaluate the suitability of a right atriotomy approach for correcting anomalous muscle bundles causing right ventricular outflow tract obstruction.
• To present a case report illustrating this surgical technique.

Main Methods:

• Review of surgical approaches for right ventricular outflow tract obstruction caused by anomalous muscle bundles.
• Presentation of a case report detailing repair through a right atriotomy.

Main Results:

• The anatomic configuration of anomalous muscle bundles may favor a right atriotomy approach for surgical correction.
• This approach may offer advantages over a right ventriculotomy in specific cases.

Conclusions:

• Repair of anomalous muscle bundles causing right ventricular outflow tract obstruction can be effectively performed through a right atriotomy.
• The right atriotomy approach is a viable and potentially advantageous alternative to right ventriculotomy for this condition.
