Modified Stumper technique for acute postoperative bifurcation stenosis causing right ventricular failure after Ross...

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Pediatric Cardiology

Background:

• The Ross procedure is a complex cardiac surgery for aortic valve disease.
• Bicuspid aortic valve and ascending aortic dilation present unique surgical challenges.
• Postoperative right ventricular failure is a rare but serious complication.

Observation:

• A 15-year-old patient developed isolated right ventricular failure immediately after a Ross procedure.
• Cardiopulmonary bypass could not be weaned in the immediate postoperative period.
• Diagnostic evaluation was crucial for identifying the cause of failure.

Findings:

• Invasive hemodynamic assessment confirmed isolated right ventricular dysfunction.
• Prompt transcatheter intervention was successfully employed in the acute postoperative setting.
• This approach effectively managed the right ventricular failure.

Implications:

• Highlights the importance of invasive assessment in managing acute postoperative complications.
• Demonstrates the feasibility and success of transcatheter interventions for right ventricular failure post-Ross procedure.
• Offers a potential treatment strategy for similar pediatric cases with severe right ventricular dysfunction.
