“Sudden cardiac arrest is the sudden cessation of cardiac activity so that the victim becomes unresponsive, with no normal breathing and no signs of circulation. If corrective measures are not taken rapidly, this condition progresses to sudden death.”
- ACC/AHA/HRS 2006 Guidelines

TCH Coronary Anomalies Program • Treat patients with congenital coronary anomalies in an
optimal and consistent way, based on the most current and reliable evidence available.
• Educate health care providers and the public about the latest information on risks, evaluation and treatment alternatives for patients with congenital coronary anomalies.
• Study the outcomes related to congenital coronary anomalies to improve the management of patients with this disease.
• Engage patients and families throughout the care management and longitudinal follow-up process to learn about their on-going experiences with this diagnosis.

• AAOCA is associated with higher risk of SCD
• The optimal management of AAOCA is controversial
• Standardized management by a dedicated multidisciplinary team provides consistent and optimal care for these patients
• Careful long-term follow-up of patients with AAOCA is necessary
