Situs inversus totalis associated with subaortic and subpulmonic stenosis

Area of Science:

• Cardiology
• Medical Genetics

Background:

• Idiopathic hypertrophic subaortic stenosis (IHSS) is a complex cardiac condition.
• Total situs inversus is a rare congenital anomaly where major visceral organs are reversed.
• Co-occurrence of these conditions presents diagnostic challenges.

Observation:

• A patient presented with angina pectoris, a symptom that initially obscured the diagnosis.
• The patient had a known diagnosis of total situs inversus.
• Simultaneous pressure recordings revealed dynamic obstruction in both the right and left ventricles.

Findings:

• The study documented dynamic obstruction in the right ventricle alongside left ventricular outflow obstruction.
• Angina-like chest pain was attributed to left ventricular outflow obstruction, not coronary artery disease.
• The presence of total situs inversus complicated the diagnostic process for IHSS.

Implications:

• This case underscores the importance of thorough patient evaluation, especially when rare conditions coexist.
• Recognizing the potential for dual cardiac obstruction is vital for accurate diagnosis and management.
• Comprehensive diagnostic approaches are essential for patients with complex congenital anomalies and cardiac symptoms.
