Left-sided Macro-reentry or Right-sided Focal Tachycardia in Patients with Prior Pulmonary Vein Isolation: A Tale of Two Atria.

We report on three patients with prior pulmonary vein isolation who presented with atrial tachycardia/atrial flutter. During electrophysiology study, the whole tachycardia cycle length was mapped to the left atrium. Multiple ablation attempts failed to terminate the tachycardia and, subsequently, right atrial mapping revealed a focal early site of origin near the superior vena cava-right atrial junction in two patients and outside the coronary sinus ostium in one patient.

Predictors of outcomes in hospitalized patients undergoing pacemaker insertion: Analysis from the national inpatient database (2016-2017).

Background: Pacemaker implantation in the U.S. is rising due to an aging population.

Hughes-Stovin syndrome: A rare cause of hemoptysis.

Multiple pulmonary artery aneurysms are seen along with venous thrombosis in Hughes-Stovin syndrome, which many investigators believe is an incomplete form of Behcet's disease. We present a case of hemoptysis with multiple pulmonary artery aneurysms, femoral vein thrombosis, and oral ulcers with emphasis on its CT features.
