Mitro-aortic fibrosa pseudoaneurysm and concomitant aortic stenosis: How to kill two birds with a stone

Area of Science:

• Cardiology
• Cardiac Surgery
• Interventional Cardiology

Background:

• Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare acquired malformation.
• It presents as a pulsatile cavity at the mitral-aortic junction, potentially leading to life-threatening complications.
• P-MAIVF is often a complication of cardiac surgery, endocarditis, or trauma.

Observation:

• This case report details a patient with severe aortic stenosis and a concomitant P-MAIVF.
• The patient was considered high-risk for conventional surgery.

Findings:

• Successful exclusion of the P-MAIVF was achieved using a transapical transcatheter aortic valve implantation (TA-TAVI) approach.
• This minimally invasive technique provided an effective solution for a complex P-MAIVF in a high-risk patient.

Implications:

• Transcatheter aortic valve implantation may represent a viable alternative treatment for P-MAIVF, particularly in patients unsuitable for open-heart surgery.
• This approach offers a less invasive option for managing this rare but dangerous cardiac condition.
• Further research into transcatheter techniques for P-MAIVF is warranted to establish its role in clinical practice.
