Empty myocardial syndrome : A risk marker of mechanical rupture during STEMI

Myocardial development is a complex process that begins in the precardiac mesoderm, and is regulated by a number of genes. Duelen R, Sampaolesi M. Stem Cell Technology in Cardiac Regeneration: A Pluripotent Stem Cell Promise. EBioMedicine. 2017 Feb;16:30-40. After formation of tubular heart , initial increase in ventricular mass during period of chamber formation is achieved by development of trabeculations. Trabecular compaction coincides with genesis of coronary circulation, and results in formation of ventricular chambers.The hallmark of sponge-like hearts delayed and poor compactive forces. Time line of ventricular compaction A deranged compaction process can be need not be macroscopic. It can be very localized, regional, or global. The timing and the quantum of compaction is an important process that injects the contractile power to the ventricle . It is increasingly observed in echocardiography that a small percentage of the population has more echo-free zones in LV myocardium than others. They are potential weak spots at times of mechanical stress. A curious case of normal Echo Sharing few images of routine echocardiography in a healthy young female. The apparent absence of mid myocardial shadow was not entirely a surprise though .At the samee time, it raises some curious thoughts as to why certain myocardial areas are not well visualized by the ultrasound. Look at the IVS, why should mid myocardium is echo free (measured 5mm) and ...
