Background:
the tissue spanning the mitral and aortic valves, the mitral-aortic intervalvular fibrosa (MAIVF), may be the site of pseudoaneurysm formation in the setting of infective endocarditis or congenital heart disease, or after valve surgery. Because of potential complications of MAIVF pseudoaneurysms, patients with such lesions are often referred for surgical repair.
Methods:
we identified 3 individuals with MAIVF pseudoaneurysms who were followed without surgical intervention after diagnosis of the MAIVF pseudoaneurysm. The courses of these patients are presented below.
Results:
the MAIVF pseudoaneurysms were measured to be stable in size over several years among 3 patients. Dimensions were 5.3 × 2.3, 7.6 × 4.9, and 4.8 × 2.5 cm. Surgical repair was considered too high a risk in 2 of the individuals, and the third individual refused a third surgical intervention. Of the 3 patients, 2 remain asymptomatic. The third patient was 87 years old when her MAIVF pseudoaneurysm was diagnosed, and she died of noncardiac causes at age 92 years.
Conclusions:
clinical surveillance and serial imaging of MIAVF pseudoaneurysms may be considered an alternative to surgical management in select individuals.
Insights
Mitral-aortic intervalvular fibrosa (MAIVF) pseudoaneurysms can be monitored non-surgically. Clinical surveillance and serial imaging may be a safe alternative to surgery for select patients with MAIVF pseudoaneurysms.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- The mitral-aortic intervalvular fibrosa (MAIVF) is a potential site for pseudoaneurysm formation.
- Pseudoaneurysms in this region can arise from infective endocarditis, congenital heart disease, or post-valve surgery.
- Surgical repair is often recommended due to potential complications of MAIVF pseudoaneurysms.
Observation:
- Three patients with MAIVF pseudoaneurysms were managed conservatively without surgical intervention.
- The pseudoaneurysms remained stable in size over several years in all three patients.
- Surgical risk was deemed too high for two patients, and the third declined further surgery.
Findings:
- MAIVF pseudoaneurysms demonstrated stable dimensions ranging from 4.8 × 2.5 cm to 7.6 × 4.9 cm over time.
- Two of the three patients remained asymptomatic during the follow-up period.
- The third patient, diagnosed at 87, died of non-cardiac causes at 92, with the pseudoaneurysm being stable.
Implications:
- Clinical surveillance and serial imaging represent a viable alternative to surgical management for select MAIVF pseudoaneurysm cases.
- Conservative management may be considered when surgical risks are high or patient preference dictates.
- This approach highlights the potential for non-invasive monitoring in specific cardiovascular conditions.
