Double discordance in the hypoplastic left heart

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease
• Neonatal Echocardiography

Background:

• Intracardiac masses in neonates can present diagnostic challenges.
• Differential diagnoses include tumors, thrombi, and structural anomalies.
• Accurate diagnosis is crucial for appropriate management.

Purpose of the Study:

• To describe a unique case of an intracardiac mass in a neonate.
• To highlight the importance of comprehensive echocardiographic analysis.
• To report a previously undescribed cardiac anomaly.

Main Methods:

• Case report of a neonate with an intracardiac mass.
• Initial diagnostic imaging and subsequent detailed segmental and sequential analysis.
• Echocardiographic evaluation.

Main Results:

• The intracardiac mass was initially misidentified.
• Thorough analysis revealed double discordance.
• A hypoplastic left ventricle was identified as the underlying condition.

Conclusions:

• A novel cardiac anomaly presenting as an intracardiac mass was identified.
• Segmental and sequential analysis is vital for diagnosing complex congenital heart disease.
• This case expands the spectrum of neonatal cardiac pathology.
