Neonatal right ventricular mass presenting with pericardial effusion and tamponade

Key Result

A rare right ventricular mesenchymal hamartoma caused neonatal cardiac tamponade, confirmed by cardiac MRI and histopathology.

Key Points

To investigate a prenatal cardiac mass in a newborn that resulted in tamponade.
Prenatal diagnosis of cardiac mass
Cardiac MRI performed for evaluation
Histopathological examination for confirmation
Right ventricular mesenchymal hamartoma identified
Cardiac tamponade resulted from the mass
This condition is rare and was previously documented only in the left ventricle

Structured PICO

Population

Newborn with prenatally diagnosed cardiac mass presenting with pericardial effusion and cardiac tamponade (n=1)

This case report documents a rare presentation of a right ventricular mesenchymal hamartoma in a newborn, expanding the known anatomical locations of this tumor.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

Abstract Prenatally diagnosed cardiac mass in a newborn caused cardiac tamponade. Cardiac MRI and histopathology confirmed a rare right ventricular mesenchymal hamartoma, previously reported only in the left ventricle.
