Spontaneous chordal rupture in a young infant with Down syndrome and unrepaired transitional atrioventricular septal defect resulted in severe left atrioventricular valve regurgitation and cardiogenic shock.
Case Report (n=1)
Highlights the need for a high index of suspicion for ruptured chordae tendinae in young infants presenting with acute pulmonary edema.
We present a unique case of spontaneous chordal rupture in a young infant with Down syndrome and unrepaired transitional atrioventricular septal defect. This resulted in abrupt onset of severe left atrioventricular valve regurgitation, cardiogenic shock, and multiorgan dysfunction. Our case highlights the need for a high index of suspicion for a ruptured chord in a young infant presenting with acute onset of pulmonary edema.
Komarlu et al. (2026) conducted a case report in Spontaneous chordal rupture in Down syndrome with unrepaired transitional atrioventricular septal defect (n=1). Spontaneous chordal rupture was evaluated on Severe left atrioventricular valve regurgitation, cardiogenic shock, and multiorgan dysfunction. Spontaneous chordal rupture in a young infant with Down syndrome and unrepaired transitional atrioventricular septal defect resulted in severe left atrioventricular valve regurgitation and cardiogenic shock.
