Insights
A pediatric patient with congenital mitral regurgitation required a second mitral valve replacement due to pannus formation. The procedure resulted in good valve function but severely depressed left ventricular function and coronary artery compression.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Interventional Cardiology
Background:
- Congenital mitral regurgitation necessitates complex surgical management.
- Pannus formation can lead to mitral valve prosthesis dysfunction.
- Pediatric cardiac surgery requires specialized approaches for valve replacement.
Abstract:
A 4-year-old girl with congenital mitral regurgitation status post mechanical mitral valve replacement (MVR) using a 16 mm Carbomedics valve (LivaNova) at the age of 5 months underwent a redo MVR using a 21 mm aortic prosthesis implanted in an inverted position for progressed increased mitral valve gradient due to pannus formation. Post operatively, echocardiogram showed good mitral valve prosthesis function with severe depressed left ventricular function (ejection fraction, 19%) and markedly segmental dyskinesia in the lateral wall. Her diagnosis of compression to the proximal dominant left circumflex artery and subsequent percutaneous coronary intervention are outlined here.
