Summary

Parachute mitral valve, a rare condition with a single papillary muscle, is typically linked to complete atrioventricular canal defects. This case highlights an ostium primum defect also associated with a single papillary muscle.

Area of Science:

Cardiology
Congenital Heart Disease
Cardiac Anatomy

Background:

Parachute mitral valve, characterized by a single papillary muscle, is a known congenital anomaly.
This condition is frequently observed in conjunction with complete atrioventricular (AV) canal defects.

Observation:

This report details a specific case involving an ostium primum defect.
The ostium primum defect in this patient was associated with a single papillary muscle.

Findings:

The study identifies an association between ostium primum defect and a single papillary muscle.
This finding expands the spectrum of cardiac anomalies linked to parachute mitral valve morphology.

Implications:

This case contributes to understanding the diverse presentations of congenital heart defects.
