Insights
A rare coronary artery anomaly in a young athlete led to cardiac arrest. Surgical repair, coronary artery bypass grafting, prevented recurrence without neurological issues.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Sports Cardiology
Background:
- Congenital coronary artery anomalies are rare but can cause significant cardiovascular events.
- Adolescent athletes are a unique population where cardiac screening is crucial for early detection.
Observation:
- A young adolescent athlete experienced sudden cardiopulmonary arrest.
- Diagnostic imaging revealed an anomalous left main coronary artery originating from the right coronary sinus.
- The anomalous vessel coursed between the aorta and pulmonary artery, a high-risk anatomical configuration.
Findings:
- The patient was successfully resuscitated and received therapeutic hypothermia.
- No neurological complications were noted during follow-up.
- Surgical intervention with coronary artery bypass grafting was performed to address the anomaly.
Implications:
- This case highlights the importance of considering rare coronary anomalies in young athletes presenting with cardiac arrest.
- Prompt diagnosis and surgical management are critical for preventing adverse outcomes.
- Coronary artery bypass grafting can effectively treat this specific anomaly, ensuring long-term athlete safety.
Abstract:
Reported herein is a coronary anomaly that occurred in a young adolescent athlete who presented with cardiopulmonary arrest. The patient was resuscitated and treated with therapeutic hypothermia. The patient had no associated neurological complications at follow up. Enhanced computed tomography of the heart indicated an anomalous left main coronary artery originating from the right coronary sinus and coursing between the aorta and the pulmonary artery. The patient underwent surgical intervention with coronary artery bypass grafting to prevent symptom recurrence.
