Rare case of mesocardia with ostium secundum ASD and double IVC

Area of Science:

• Cardiology
• Medical Imaging
• Pediatric Congenital Anomalies

Background:

• Mesocardia is a rare congenital cardiac anomaly, occurring in approximately 0.2% of cases.
• Congenital heart anomalies often present with associated cardiovascular abnormalities.
• Early and accurate diagnosis is crucial for managing associated conditions and improving patient outcomes.

Observation:

• A patient presented with symptoms suggestive of an atrial septal defect (ASD) with a left-to-right shunt, leading to pulmonary congestion and recurrent pneumonia.
• Diagnostic workup revealed an extremely rare combination of mesocardia and a double inferior vena cava (IVC).

Findings:

• The case highlights the co-occurrence of mesocardia with other congenital anomalies, specifically ASD and double IVC.
• Thorough investigation uncovered these rare conditions, which were not the initial presenting diagnoses.
• The patient's condition emphasized the importance of a comprehensive diagnostic approach for congenital cardiac anomalies.

Implications:

• This case underscores the necessity of a meticulous workup for all congenital cardiac anomalies to identify associated vascular and cardiac conditions.
• Recognizing rare combinations like mesocardia with double IVC can guide future diagnostic strategies.
• Such detailed case reports contribute valuable data for understanding the spectrum and clinical significance of rare congenital heart diseases.
