The treatment of noncompaction of ventricular myocardium

Advances in symptomatic therapy for left ventricular non-compaction in children

Left ventricular non-compaction is a complex cardiomyopathy and the third largest childhood cardiomyopathy, for which limited knowledge is available. Both pathogenesis and prognosis are still under investigation. Currently, no effective treatment strategy exists to reduce its incidence or severity, and symptomatic treatment is the only clinical treatment strategy. Treatment strategies are constantly explored in clinical practice, and some progress has been made in coping with the corresponding symptoms because the prognosis of children with left ventricular non-compaction is usually poor if there are complications. In this review, we summarized and discussed the coping methods for different left ventricular non-compaction symptoms.

[Left ventricular non - compaction: contemporary view of genetic background, clinical course, diagnostic and treatment]

This review highlights and discusses recent advances in understanding left ventricular non - compaction (LVNC). Clinical profile, prognosis and even diagnosis are still a great challenge faced by the world. The population prevalence of left ventricular non - compaction remains unknown. High variability of clinical manifestations, genetic heterogenity with overlap of different phenotypes, variability of hereditary patterns suggests that LVNC seems to be rather an isolated trait or a part of phenotypic expression of different cardiac diseases or complex genetic syndromes.

Sudden death due to biventricular non-compaction cardiomyopathy in a 14-year-old

A 14-year-old African-American female with a long-standing medically and ablation-treated history of tachycardia with associated seizures died suddenly. Upon autopsy, evidence of gross non-compaction involving the left ventricle, as well as possible subtle non-compaction of the right ventricle was discovered. Microscopically, there was focal myocyte hypertrophy as well as myxoid connective tissue and subendocardial fibroelastosis in the areas affected by the non-compaction. Arrhythmia, precipitated by the underlying cardiomyopathy, led to this young girl's death. Non-compaction cardiomyopathy is a rare cardiac disorder which commonly goes undiagnosed until post-mortem, although diagnosis through echocardiogram, CT, or MRI is possible and there is criterion for diagnosis with each of these.
