Of the 400,000–500,000 permanent pacemaker leads implanted worldwide each year, around 10% may eventually fail or become infected, becoming potential candidates for removal. Intravascular techniques removing problematic infected evolved over a 5‐year period (1989–1993). This article analyzes results from January 1994 through April 1996, during which were fairly stable. Extraction of 3,540 2,338 patients was attempted at 226 centers. Indications were: infection (27%), nonfunctional...

A recent American Heart Association (AHA) statement1 recommended electrocardiograms (ECGs) routinely for children before they start medications to treat attention-deficit/hyperactivity disorder (ADHD). The AHA statement reflected the thoughtful work of a group committed improving health with heart disease. However, recommendation obtain an ECG starting treating ADHD contradicts carefully considered and evidence-based recommendations Academy Child Adolescent Psychiatry2 Pediatrics (AAP).3,4...

udden cardiac death (SCD) in the young (SCDY) has a devastating impact on families, care providers, and community attracts significant public media attention.Sudden is defined as an abrupt unexpected due to cardiovascular cause, typically occurring Ͻ1 hour from onset of symptoms.Depending source, "young" variably those less than 25, 30, 35, or 40 years age.][3] Sudden infant syndrome (SIDS) may be related SCD some infants.Sudden sudden year age that cannot explained after thorough...

Myocardial dysfunction and coronary abnormalities are prominent features of multisystem inflammatory syndrome in children (MIS-C). In this study we aim to evaluate the early midterm outcomes MIS-C.This is a longitudinal 6-month cohort all admitted treated for MIS-C from April 17 June 20, 2020. Patients were followed ∼2 weeks, 8 6 months postadmission, with those aneurysms evaluated more frequently.Acutely, 31 (62%) patients required intensive care vasoactive support, 26 (52%) had left...

In order to assess the psychological profile of patients with malignant ventricular tachyarrhythmias, eight who underwent implantation automatic internal cardioverter defibrillator for refractory arrhythmias were evaluated. Six men and two women a mean age 53 years examined Symptom Checklist-90, State Trait Personality Inventory specifically designed questionnaire about defibrillator. The group studied manifested high degrees both anger anxiety compared normal controls or other medically ill...

To determine the sequela of right ventricular pacing in children with congenital complete atrioventricular block.Pacing is a well-accepted therapy for patients block. The long-term this population has not been well described.We performed cohort study on all block who underwent pacemaker implantation at our institution from 1972 to 2004. Patients associated heart disease or dysfunction prior were excluded.A total 63 included study. median age was 6.5 years, an average follow-up 9.9 years....

Background: Because of venous occlusion, intracardiac shunting, previous surgery, or small size placement implantable cardioverter‐defibrillator (ICD) leads may not be possible using traditional methods. The purpose this study was to evaluate and describe innovative methods placing ICD leads. Methods: records all patients undergoing implantation at our institution were reviewed identify with nontraditional lead placement. Indications for ICD, method coil placement, defibrillation thresholds,...

Background Heart failure (HF) accounts for >3 million hospital admissions annually in adults with acquired cardiovascular disease, but there are limited data on HF congenital heart disease (ACHD). The purpose of this study was to test the hypotheses that common ACHD and associated significant morbidity mortality. Methods 2007 Nationwide Inpatient Sample used assess national prevalence, morbidities, risk factors mortality during hospitalizations among HF. Results Of 84 308 (95% CI 71 345–97...

Article AbstractBackground: The literature on predictors of response to treatment nonchronic major depression has identified shorter duration illness, acute onset, and less severity illness as positive predictors. Unfortunately, there are almost no data for chronic depression. This study examined pharmacotherapy (sertraline or imipramine) in the outpatients who had DSM-III-R-defined double depression.Method: phase Chronic Major Depression Double Study is a double-blind, randomized,...
