ALCAPA and ASD Secundum Unmasked by Severe Postpartum Haemorrhage Complicated by Heart Failure

Area of Science:

• Cardiology
• Congenital Heart Disease
• Medical Genetics

Background:

• Abnormal Left Coronary Artery from Pulmonary Artery (ALCAPA) is a rare congenital coronary anomaly.
• This condition involves the left main coronary artery originating from the pulmonary trunk, creating a left-to-right shunt.
• ALCAPA often co-occurs with other cardiac defects, such as atrial septal defects and patent ductus arteriosus.

Observation:

• The case presented involved ALCAPA with a secundum atrial septal defect.
• Sudden cardiac death is a significant potential complication of ALCAPA.
• Hemodynamic alterations resulting from this specific shunt combination were analyzed.

Findings:

• Management strategies for ALCAPA, particularly concerning shunt hemodynamics during pregnancy, were outlined.
• Pregnant individuals with ALCAPA face elevated risks, necessitating meticulous peri- and postpartum care.
• Surgical intervention to establish dual coronary circulation proved effective.

Implications:

• Successful surgical correction allows patients with ALCAPA to carry subsequent pregnancies to term.
• This case underscores the critical need for specialized management of pregnant ALCAPA patients.
• Optimal peri- and postpartum care is essential for improving outcomes in pregnant women with ALCAPA.
