Insights
Hypertrophic cardiomyopathy can coexist with myocardial bridging of the left anterior descending coronary artery. Diagnosis in these two patients involved advanced imaging techniques like echocardiography and coronary angiography.
Area of Science:
- Cardiology
- Cardiovascular Imaging
Background:
- Hypertrophic cardiomyopathy (HCM) is a primary cardiac condition.
- Myocardial bridging (MB) is a congenital anomaly where a coronary artery segment courses through the myocardium.
- The association between HCM and MB is infrequently reported.
Observation:
- Two patients presented with symptoms suggestive of cardiac compromise.
- One patient experienced angina and syncope; the other reported chest pain and dyspnea.
- Clinical presentation indicated potential underlying coronary or myocardial pathology.
Findings:
- Both patients were diagnosed with hypertrophic cardiomyopathy.
- Myocardial bridging of the left anterior descending coronary artery was identified in both cases.
- Cross-sectional echocardiography and coronary angiography confirmed the co-occurrence of HCM and MB.
Implications:
- This association highlights the importance of considering MB in HCM patients with concerning symptoms.
- Advanced imaging modalities are crucial for accurate diagnosis of complex cardiac conditions.
- Further research may elucidate the pathogenetic relationship and clinical significance of combined HCM and MB.
Abstract:
Two patients are reported in whom hypertrophic cardiomyopathy was associated with myocardial bridging of the left anterior descending coronary artery. One had a history of angina and recurrent syncope, the other had chest pain and exertional dyspnoea. In each case the diagnosis was made by cross-sectional echocardiography and coronary angiography.
