Summary
Surgical resection of atrioventricular valve myxomas can be achieved conservatively, avoiding valve replacement. Novel techniques like chordal transposition and pericardial patching preserve valve function in complex myxoma cases.
Area of Science:
- Cardiovascular Surgery
- Cardiac Oncology
- Valvular Heart Disease
Background:
- Atrioventricular valve myxomas often necessitate surgical intervention due to high embolic risk.
- Tumor characteristics, such as sessile nature or large peduncle, can complicate complete excision and may lead to valve replacement.
Observation:
- Two cases of atrioventricular valve myxoma are presented where valve replacement was successfully avoided.
- One patient had a mitral myxoma requiring chordal transposition and leaflet resection to maintain valve competence.
- A tricuspid myxoma with a large stalk was resected and the leaflet reconstructed with a pericardial patch.
Findings:
- Conservative surgical resection techniques can be effective for atrioventricular valve myxomas.
- Chordal transposition successfully preserved mitral valve competence after myxoma excision.
- Pericardial patch reconstruction effectively restored tricuspid leaflet integrity.
Implications:
- These findings suggest that valve-sparing surgery is feasible for select atrioventricular valve myxomas.
- Peroperative transesophageal echocardiography is crucial for guiding conservative surgical strategies.
- Minimally invasive approaches may reduce morbidity associated with valve replacement in myxoma cases.
