Overview
Acardia is a severe congenital anomaly characterized by the absence of a heart and other major organs in one twin, typically developing parasitically dependent on the co-twin for survival 1.Diagnosis
Prenatal ultrasound is crucial for diagnosis, identifying the acardiac twin through abnormal vascular connections and lack of cardiac development 1.
Doppler studies may help assess placental vascular anastomoses and hemodynamic relationships between twins 1.Management
First-line treatment: Monopolar thermocoagulation to occlude abnormal blood vessels supplying the acardiac twin, aiming to reduce parasitic burden on the normal twin 1.
Adjunctive care: Close monitoring of both twins post-procedure for signs of distress or complications 1.Special Populations
Pregnancy: Management focuses on selective reduction techniques to improve survival rates of the normal co-twin 1.
Comorbidities: Specific management strategies for comorbidities are not detailed in the provided abstracts 1.Key Recommendations
Utilize monopolar thermocoagulation for selective reduction in cases of acardiac twinning to enhance survival outcomes of the normal twin (Evidence: Weak) 1.
Perform detailed prenatal ultrasound and Doppler studies for accurate diagnosis and assessment of vascular connections (Evidence: Weak) 1.
Implement close postnatal monitoring for both twins following interventional procedures to manage potential complications (Evidence: Expert opinion) 1.References
