Persisting myocardial sinusoids of both ventricles as an isolated anomaly: echocardiographic, angiographic, and
Insights
Persistent myocardial sinusoids, abnormal heart vessels, can cause progressive heart failure. This case highlights the importance of recognizing this rare condition in young adults with unexplained cardiomyopathy.
Area of Science:
- Cardiology
- Pathology
- Medical Imaging
Background:
- Myocardial sinusoids are vascular channels within the heart muscle.
- Their persistence as an isolated anomaly is rare.
- This condition can lead to significant cardiac dysfunction.
Observation:
- A 21-year-old patient presented with progressive heart failure.
- Echocardiography revealed channel-like structures in thickened, hypokinetic ventricles.
- Angiography demonstrated a honeycomb-like ventricular inner contour.
Findings:
- The autopsy confirmed the diagnosis of persistent myocardial sinusoids.
- The anomaly was associated with thickened ventricular myocardium.
- This represents an isolated finding without other apparent cardiac defects.
Implications:
- This case underscores the need to consider persistent myocardial sinusoids in young patients with idiopathic cardiomyopathy.
- Accurate diagnosis through advanced imaging is crucial for understanding cardiac failure etiology.
- Recognition of this rare anomaly aids in patient management and prognosis assessment.
Abstract:
The persistence of myocardial sinusoids in both ventricles as an isolated anomaly is described. A 21-year-old patient had progressive heart failure considered as cardiomyopathy of obscure etiology. Two-dimensional echocardiography demonstrated channel-like structures in the thickened myocardium of both hypokinetic ventricles. Angiography showed a honeycomblike inner contour in both ventricles. Autopsy proved the diagnosis of persistent sinusoids in a thickened myocardium.
