Right Anterior Mini-Thoracotomy for Discrete Fibromembranous Subaortic Stenosis

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Adult Congenital Heart Disease

Background:

• Discrete fibromembranous subaortic stenosis is a significant cause of left ventricular outflow tract obstruction.
• Conventional surgical repair typically involves a midline sternotomy approach.
• Minimally invasive techniques are increasingly explored for cardiac procedures.

Observation:

• This case report details the surgical management of an adult patient with discrete fibromembranous subaortic stenosis.
• The procedure was performed using a right mini-thoracotomy approach.
• Central cannulation was utilized, allowing for direct operative vision during membrane resection.

Findings:

• Successful resection of the subaortic membrane was achieved through a right mini-thoracotomy.
• The minimally invasive approach facilitated direct visualization of the operative field.
• The patient tolerated the procedure well, indicating feasibility of this technique.

Implications:

• Right mini-thoracotomy offers a viable alternative to sternotomy for discrete subaortic stenosis repair.
• Minimally invasive cardiac surgery may lead to reduced patient recovery times and improved cosmetic outcomes.
• This approach warrants further investigation in larger patient cohorts for subaortic membrane resection.
