Early ICD lead failure in defibrillator systems with multiple leads via cephalic access.

Introduction: Implantable cardioverter defibrillators (ICDs) are proven to prevent sudden death in patients at elevated risk for sustained ventricular tachycardia or fibrillation. Complications related to ICD failure can stem from lead dysfunction, manufacturing defects, patient characteristics, or implantation technique. We conducted a review of all ICD leads implanted at our center from 2011 to 2017 to determine risk factors for premature lead failure.

The Importance of Subclavian Angiography in the Evaluation of Chest Pain: Coronary-Subclavian Steal Syndrome.

Routine preoperative screening for the presence of brachiocephalic disease using ultrasonic duplex or angiography is a cost-effective and essential means to prevent the development of rare occurrences of coronary-subclavian steal syndrome.

QT Prolongation and Clinical Outcomes in Patients with Takotsubo Cardiomyopathy.

Background: Takotsubo cardiomyopathy (TCM) has been associated with repolarization abnormalities including QT prolongation and acquired long QT syndrome. However, the association between QT prolongation and clinical outcomes in patients with TCM remains unclear. The aim of this study is to examine the association between QT prolongation and ventricular arrhythmias, cardiogenic shock, and death in patients with TCM.

Refractory Case of Paroxysmal Autonomic Instability With Dystonia Syndrome Secondary to Hypoxia.

Paroxysmal autonomic instability with dystonia (PAID) is a syndrome commonly related to traumatic brain injury (TBI) and rarely to anoxia associated with symptoms of dystonia, tachycardia, tachypnea, and diaphoresis. This is a case of a 20-year-old man who was stabbed in the heart. He underwent surgical repair of a ventricular septal defect and mitral valve replacement.
