At the transition from the non-coronary cusp of the aortic valve to the anterior mitral leaflet, there is the avascular region called the mitral-aortic intervalvular fibrosa (MAIVF), and pseudoaneurysms can form due to various factors.
In this report, two patients who were scheduled for revision aortic surgery for a pseudoaneurysm of the MAIVF (P-MAIVF) after aortic valve root replacement. The patients were found to have P-MAIVF, which could not be diagnosed by contrast enhanced CT and transthoracic echocardiography before surgery. The P-MAIVF was confirmed by intraoperative transesophageal echocardiography, which contributed to the accurate location of the MAIVF and the selection of the procedure.
When P-MAIVF is suspected based on surgical and medical history, a transesophageal echocardiography evaluation can provide information about the lesion to the surgeon and contribute to the selection of an appropriate operative method.
