Isolated Non-Compaction of Right Ventricular Myocardium, A Rare Congenital Anomaly and Role of Echocardiogram: A Case Report

The ventricular non-compaction or spongy myocardium is a rare congenital cardiomyopathy which is caused by defective morphogenesis of myocardium during embryonic life. It is characterised by excessive, coarse trabeculations within ventricular myocardium beyond papillary muscle insertion which communicates freely with the ventricular cavity. This carries high risk for development of serious arrhythmia, thromboembolic stroke, pump failure etc. Isolated LV involvement is the most common presentation (68%) and biventricular involvement is the next most common presentation (22-38%). Isolated non-compaction of RV myocardium is a rare anomaly. We are hereby presenting such a case.

Cardiac Complications of Liquid Protein Diets

<h3>To the Editor.—</h3> Two articles in a recent issue ofThe Journalby Singh et al (240:115, 1978) and Brown et al (240:120,1978) report the deaths from refractory ventricular tachycardia and fibrillation of three young women, obese but apparently otherwise healthy, who had been given a program of weight reduction by fasting with liquid protein. Each of the three had been fasting for five or six months and had lost about 41 kg. In each case the ECG on admission was marked by gross QT_cprolongation. Singh et al state: "It is not known what proportion of patients using various liquid protein diets have such ECG abnormalities and whether all such patients are at risk for the development of serious arrhythmias." In connection with the programs of supplemented fasting with protein of high biologic availability, carbohydrates, and minerals at The Mount Sinai Hospital of Cleveland and at the University
