New atrial fibrillation diagnosed by 30-day rhythm monitoring.

Background: Recent studies of patients with pacemakers and implantable cardioverter/defibrillators have shown that subclinical atrial fibrillation (AF) is common and is associated with thromboembolic risk. We sought to evaluate the frequency, characteristics, and impact of new AF diagnosed by ambulatory 30-day rhythm monitoring.

Methods: The 30-day rhythm monitoring data from January 2010 to August 2015 at our institution were reviewed.

Descending septal branch of right coronary artery: Rare, but important in hypertrophic cardiomyopathy.

A 54year old man with hypertrophic cardiomyopathy was evaluated for alcohol septal ablation. However there were no sizeable septal branches from the left anterior descending artery supplying the basal septum. He was found to have a rare variant, the descending septal branch from ostial right coronary artery and underwent ablation through the same.
