INTRODUCTION Chronic kidney disease (CKD) has been independently associated with increased cardiovascular mortality. Little is known about the benefit of implantable cardioverter defibrillator (ICD) therapy for prevention of sudden death in this large, high-risk population. We sought to evaluate the impact of CKD on survival in patients who received an ICD(More)
OBJECTIVES The purpose of this study was to evaluate the long-term outcomes of patients with unexplained syncope, ischemic or nonischemic cardiomyopathy, and a negative electrophysiologic study (EPS). BACKGROUND EPS is frequently performed to evaluate syncope in patients with left ventricular dysfunction. Limited long-term data evaluating all-cause(More)
BACKGROUND A novel magnetic guidance system has been developed that allows the operator to remotely navigate an electrophysiology mapping/ablation catheter to precise locations in the heart for treatment of tachyarrhythmias. To date, this new technology has not been directly compared with the conventional approach. OBJECTIVE To compare the use of the(More)
BACKGROUND Cigarette smoking is a known risk factor for sudden cardiac death (SCD). It is unknown whether smoking status affects implantable cardioverter-defibrillator (ICD) therapy. OBJECTIVE The primary end point was appropriate ICD therapy according to smoking status. METHODS A total of 105 consecutive patients who underwent ICD implantation for(More)
Ablation procedures for arrhythmias have increased in frequency and complexity over the last decade. Improvements in technology have allowed for less reliance on fluoroscopy to guide these procedures. Ablation without fluoroscopy has been reported in small cohorts. We report a single center experience of fluoroless ablation after adoption of this technique(More)
This trial evaluates reproductive performance in a early-routine estrus synchronization program using two different PGF2? . Cows were administered D(+)cloprostenol sodium (n=88; Group A) or dinoprost (n=78; Group B) between 35-42d postpartum. Pedometers were used to detect estrus. Evaluation of secondary signs of estrus and evaluation of vaginal mucus(More)
BACKGROUND Venous air embolism due to orogenital sex in pregnancy is an uncommon clinical event. CASE A previously healthy, 29-week pregnant woman presented to the emergency room unconscious 1 hour after engaging in orogenital sex with her partner. The cardiology service was consulted due to troponin elevation. Assessment was that the patient had likely(More)
Early repolarization (ER) syndrome is characterized by ≥1 mV J-point elevation in 2 contiguous inferior and/or lateral ECG leads in a patient resuscitated from otherwise unexplained VF or polymorphic VT. J-point elevation in these patients may have slurring or notching of the end of the QRS complex. While alterations in temperature have been known to effect(More)
A spayed Samoyed bitch, 12 years old, was presented to the Veterinary Clinical Hospital of the University of Cordoba (Spain) with abundant vulvar sanguineous discharge over the previous three days. The clinical examination revealed a remarkable vulvar mass, which protruded through the vulvar lips. Abdominal ultrasonography revealed the presence of(More)
