Abstract

Implantation of electrophysiological cardiac devices such as pacemakers and implantable cardioverter defibrillators has become a widely available and routine procedure in cardiovascular medicine. One of the most feared complications of device implementation is infection. Infection rates for these devices are reported to vary between 0.7% and 7.0%. Cardiac thromboembolic event is a recognized complication of permanent cardiac rhythm devices with an incidence of 0.6%-3.5%, unrelated to lead size or number. These complications are associated with high morbidity and mortality rates. In this case report, right atrial mass, right atrial abscess, perforation of tricuspid septal leaflet, and pulmonary embolism secondary to ICD lead endocarditis is presented.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
