High risk and low incidence diseases: Cyanotic critical congenital heart disease.

INTRODUCTION

Cyanotic critical congenital heart disease (CCHD) is a serious condition associated with high rate of morbidity and mortality.

OBJECTIVE

This review highlights key aspects of CCHD, including presentation, diagnosis, and management in the emergency department (ED), based on current evidence.

DISCUSSION: CCHD encompasses several conditions, including truncus arteriosus, dextro-transposition of the great arteries (d-TGA), tricuspid atresia, tetralogy of Fallot (TOF), total anomalous pulmonary venous return (TAPVR), Ebstein's anomaly, critical pulmonary stenosis, and hypoplastic left heart syndrome (HLHS). These conditions should be considered in critically ill neonates presenting with shock and cyanosis. Evaluation involves a thorough assessment of the patient's cardiovascular and respiratory status. Diagnostic tools include pulse oximetry, laboratory testing, electrocardiogram, chest radiography, and ultrasonography. Management requires prompt recognition and hemodynamic stabilization, which may involve the administration of antibiotics, prostaglandins, vasoactive/inotropic agents, and airway management. Expert consultation and coordination of transfer to a tertiary or quaternary care center are crucial. Surgical repair serves as the definitive treatment.

CONCLUSION

A thorough understanding of cyanotic congenital heart disease is essential for emergency clinicians to effectively diagnose and manage this potentially life-threatening condition.
