Pseudoaneurysm of the mitral-aortic intervalvular fibrosa: a rare case after percutaneous transluminal coronary angioplasty

BMC Cardiovasc Disord. 2023 Sep 26;23(1):477. doi: 10.1186/s12872-023-03512-4.

Abstract

Background: Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is an uncommon but potentially life-threatening condition. The most common pathogenic factors of P-MAIVF are infective endocarditis and surgical valve operation. Here, we report a rare case of P-MAIVF which occurred one year after percutaneous transluminal coronary angioplasty (PTCA).

Case presentation: A 31-year-old man developed a P-MAIVF one year after PTCA. Transthoracic echocardiography (TTE) revealed a pseudoaneurysm between the aortic root and the left atrium. Three-dimensional transesophageal echocardiography (3D-TEE) clearly demonstrated the orifice of the pseudoaneurysm. This case was initially diagnosed by ultrasound, and the prognosis was good after surgical repair.

Conclusions: We report a rare case of P-MAIVF that occurred one year after PTCA.
