Anomalous coronary artery simulating parachute mitral valve.

Area of Science:

• Cardiology
• Congenital Heart Disease
• Cardiac Imaging

Background:

• Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect.
• ALCAPA can present with symptoms mimicking other cardiac conditions, posing diagnostic challenges.

Observation:

• The study reports a case where ALCAPA led to myocardial and papillary muscle fibrosis.
• This fibrosis resulted in physiological and radiological abnormalities.

Findings:

• The observed abnormalities closely resembled those seen in parachute mitral valve (PMV).
• Fibrous atrophy of the myocardium and anterior papillary muscle was a key finding.

Implications:

• This case highlights the importance of considering ALCAPA in the differential diagnosis of parachute mitral valve.
• Accurate diagnosis is crucial for appropriate management and to prevent complications associated with myocardial dysfunction.
