Left ventricular non-compaction and its cardiac and neurologic implications

Area of Science:

• Cardiology
• Developmental Biology
• Medical Imaging

Background:

• Left ventricular non-compaction (LVHT) is a rare cardiomyopathy characterized by excessive myocardial trabeculations.
• It is often congenital, stemming from abnormal embryonic development, but can be acquired.
• LVHT can occur independently or with other cardiac and non-cardiac conditions.

Purpose of the Study:

• To describe the morphological characteristics of left ventricular non-compaction (LVHT).
• To review the etiology, diagnostic methods, associated conditions, and clinical complications of LVHT.
• To discuss the management and prognosis of LVHT.

Main Methods:

• Review of existing literature on left ventricular non-compaction (LVHT).
• Analysis of diagnostic findings from transthoracic echocardiography and cardiac MRI.
• Correlation of LVHT with genetic, neuromuscular, and chromosomal abnormalities.

Main Results:

• LVHT presents as a meshwork of myocardial fibers, predominantly at the apex and lateral wall.
• Common complications include ventricular arrhythmias, systolic dysfunction, embolism, and sudden cardiac death.
• LVHT is frequently associated with hereditary conditions and chromosomal aberrations.

Conclusions:

• Left ventricular non-compaction (LVHT) is a distinct morphological abnormality with significant clinical implications.
• While LVHT itself may not require treatment, managing its complications is crucial.
• Improved awareness and timely therapy have led to a better prognosis for LVHT patients.
