Severe aortic regurgitation complicating percutaneous aortic valve valvuloplasty

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Percutaneous aortic balloon valvuloplasty is a procedure to treat aortic valve stenosis.
• Tricuspid aortic valves are the most common type of aortic valve.
• Aortic regurgitation is a condition where the aortic valve does not close properly, leading to blood leaking back into the left ventricle.

Observation:

• An 88-year-old patient with mild aortic regurgitation underwent percutaneous aortic balloon valvuloplasty.
• Following balloon dilatation, the patient developed severe aortic regurgitation.
• Surgical examination revealed no anatomical disruption of the aortic valve or its supporting structures.

Findings:

• Development of severe aortic incompetence following balloon valvuloplasty is a rare and previously unreported complication.
• The tricuspid aortic valve morphology may influence the risk of developing severe aortic regurgitation post-procedure.
• The exact mechanism leading to severe aortic regurgitation without structural valve damage requires further investigation.

Implications:

• This case highlights a potential risk associated with percutaneous aortic balloon valvuloplasty, particularly in patients with tricuspid aortic valves.
• Further research is needed to understand the mechanisms and identify predictive factors for this complication.
• Clinicians should be aware of this potential adverse event and consider careful patient selection and monitoring.
