Insights
This study reports the first successful surgical repair of a rare combination of congenital heart defects in a 12-month-old infant. The infant underwent mitral valve replacement and defect closure, showing excellent long-term recovery.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
- Cardiovascular Medicine
Background:
- Congenital heart defects require timely intervention for optimal outcomes.
- Parachute mitral valve, ventricular septal defects, and coronary sinus septal defects present complex surgical challenges.
- Pulmonary artery hypertension and heart failure can complicate these conditions.
Observation:
- A 12-month-old infant with a parachute mitral valve, ventricular septal defect, and coronary sinus septal defect presented with progressive pulmonary artery hypertension and heart failure.
- Echocardiogram and angiogram confirmed the diagnosis of these combined congenital anomalies.
- The infant underwent successful mitral valve replacement with a Björk-Shiley prosthetic valve and patch closure of septal defects.
Findings:
- The surgical intervention for this rare combination of congenital heart anomalies was technically successful.
- Postoperative recovery was uneventful, with the patient remaining well at 3-year follow-up.
- This case represents the first reported successful surgical management of this specific constellation of congenital heart defects.
Implications:
- This case highlights the feasibility of surgical correction for complex congenital heart defects in infants.
- Successful outcomes in such cases can improve long-term prognosis and quality of life.
- Further research into surgical techniques for rare congenital anomalies is warranted.
Abstract:
A 12-month-old infant, weighting 6.7 kg, underwent mitral valve replacement with a 17 mm Björk-Shiley prosthetic valve for parachute mitral valve, and patch closure of the associated ventricular and coronary sinus septal defects. Progressive pulmonary artery hypertension and heart failure required surgical intervention. The diagnosis of parachute mitral valve and associated lesions was established by echocardiogram and angiogram. Postoperative recovery was uneventful and he is doing well 3 years after the operation. To our knowledge this is the first successful case to be reported in the literature with such combination of the congenital anomalies.
