Cytotoxic immune cells mediate precise attacks against diseased cells to maintain organismal health. Their operational unit of killing and host defense is lytic granules (LGs), which are specialized lysosomal-related organelles. Precision in cytotoxicity is achieved by converging the many LGs to the microtubule-organizing center (MTOC) and polarizing these to the diseased cell for secretion.

We encountered a single case in which a transition between orthodromic reciprocating tachycardia with a concealed nodoventricular pathway and atrioventricular nodal reentrant tachycardia with a bystander nodoventricular pathway was observed.

Anomalous aortic origin of a coronary artery is a rare congenital heart defect. The detection of anomalous coronary arteries is likely to increase with increased availability and application of cardiac computed tomography and magnetic resonance imaging. Once detected, the recommendation for surgical intervention on anomalous coronary arteries depends upon patient symptoms, the presence or absence of inducible ischemia on stress imaging, and high-risk anatomic features.

Left bundle branch block (LBBB) causes immediate electrical and mechanical dyssynchrony of the left ventricle (LV) and gradual structural damages in the Purkinje cells and myocardium. Mechanical dyssynchrony reduces the LV ejection fraction (EF) instantly, but only to ≈55% in an otherwise normal heart. Because of the heart's in-built functional redundancy, a patient with LBBB does not always notice the heart's reduced efficiency straightaway.
