Summary
Three patients with hypertrophic cardiomyopathy (HC) and left ventricular (LV) apical diverticula experienced severe midventricular obstruction. This obstruction was characterized by elevated LV systolic pressure and significant LV outflow pressure gradients.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Hypertrophic cardiomyopathy (HC) is a primary cardiac condition.
- Left ventricular (LV) apical diverticula are rare congenital anomalies.
- Midventricular obstruction is a severe manifestation of HC.
Observation:
- This study describes three patients diagnosed with HC and LV apical diverticula.
- The diverticula varied in size among the patients.
- Morphologic evidence indicated severe midventricular obstruction in all three cases.
Findings:
- Two patients exhibited significantly elevated LV systolic pressure.
- Marked LV outflow pressure gradients were documented in two patients.
- The combination of HC, LV apical diverticula, and severe obstruction presents a unique clinical challenge.
Implications:
- Understanding this specific patient cohort can refine diagnostic and therapeutic strategies for HC.
- Further research into the pathophysiology of LV apical diverticula in HC is warranted.
- These findings may inform surgical approaches for managing complex obstructive patterns in HC.
