Background: Permanent cardiac implantable electronic devices (CIEDs) are traditionally implanted with the assistance of fluoroscopy. While clinically effective, this technique exposes both patients and providers to radiation which is associated with adverse health effects and represents an occupational hazard. In this study, we investigate the safety and feasibility of permanent CIED placement under the guidance of transthoracic echocardiography (TTE). There is also increasing interest in use of non‐fluoroscopic options for noninvasive cardiac electrophysiologic procedures.Methods: Fifteen patients consecutively consented for initial implant of CIEDs, specifically dual chamber pacemakers (DCPM) and dual chamber implantable cardioverter defibrillators (DCICDs). Patients were excluded if they had previous implants, abandoned leads, or anatomic anomalies including congenital and known persistent left superior vena cava (PLSVC). We used TTE to guide and implant atrial and ventricular leads.Results: Eleven patients received DCPMs and four patients received DCICDs. The procedure duration was 49.3 min for DCICD and 52.3 min for DCPM, p = .807. The average number of right atrial lead attempts was 1.6 for DCPMs and 1.8 for DCICD, p = .860. The average number of right ventricular lead attempts for DCPMs was 2.2 and 1.0 attempt for DCICDs, p = .044. There were no complications at 90‐day follow‐up.Conclusion: We demonstrate the feasibility of TTE‐guided DCPM/DCICD implantation without use of fluoroscopy. We present this method as a safe alternative for permanent CIED placement that may reduce risk of radiation exposure and cost while maintaining safety and efficacy. No operators wore lead aprons during the procedure.

BACKGROUND Congestive heart failure (CHF) affects over 23 million individuals worldwide and over 5.8 million individuals in the United States. Left ventricular assist device (LVAD) implantation is used as both a bridging and destination therapy for patients with advanced CHF. LVADs are reported to cause ventricular arrhythmias. Ventricular tachycardia and ventricular fibrillation (VF) are common fatal arrhythmias in patients with severe CHF if left untreated. We report a case in which a patient with an LVAD without an implantable cardioverter device (ICD) developed VF with non-classical symptoms with an unknown duration prior to defibrillation. CASE REPORT A 74-year old man was brought to the hospital via Emergency Medical Services (EMS) with a 1-day history of altered mental status, somnolence, and slurred speech. His past medical history was significant for CHF with LVAD Heart Mate II. An initial electrocardiogram (ECG) done by EMS was abnormal but was presumed to be an artifact secondary to LVAD. A 12-lead ECG done in the Emergency Center revealed VF. He required electrical defibrillation. Due to ongoing multiple organ failure, he was admitted to the Intensive Care Unit (ICU) for further care. CONCLUSIONS In the management of VF, the time to defibrillation is of paramount importance. LVAD patients could be in VF and present with non-specific symptoms. EMS personnel should be aware of this, as it can appear to be an artifact on ECG.

Pertussis is a vaccine-preventable disease with an incidence that has been trending upwards in the United States over the last two decades. This is evident by an increase in the incidence from 10,100 cases in 1974 to a peak of >48,000 cases noted in the last decade. Pertussis disease severity ranges from mild to severe, with resultant complications capable of causing significant morbidity and mortality. We report a case of pertussis in a 5-week-old female infant who presented with fever, paroxysms of cough, apnea, and seizures leading to cardiopulmonary arrest. Cardiopulmonary resuscitation lasted 11 minutes before the return of spontaneous circulation. She was transferred to our tertiary facility and admitted to the pediatric intensive care unit. Complete blood count revealed significant leukocytosis, chest X-ray revealed bilateral pulmonary edema with pleural effusion, and echocardiogram demonstrated pulmonary hypertension. Bordetella pertussis infection was confirmed on respiratory polymerase chain reaction. She was treated with antibiotics, ventilatory management, and other supportive care. She was discharged on room air after a hospital course of 7 weeks with care coordination between her primary care provider, pulmonologist, and neurologist. Despite the positive outcome in this case, it is important to note that managing severe pertussis involves multidisciplinary care, and the morbidity and cost implications can be mitigated on a population scale through vaccine optimization strategies.

Atrial fibrillation is the most common dysrhythmia, affecting about 6 million people in the United States. Atrial fibrillation has been shown to be an independent risk factor for stroke. Atrial tachycardia are common findings on Holter monitoring in the general population and may be associated with the development of atrial remodeling and atrial fibrillation inducibility. Studies have shown that atrial tachycardia is associated with the development of atrial fibrillation and subsequent stroke. The American Heart Association current guidelines recommend the use of oral anticoagulants in patients with atrial fibrillation and an elevated CHA2DS2-VASc ≥2 in men or ≥3 in women. However, anticoagulant therapy is not currently recommended in patients with atrial tachycardia despite increasing evidence of its association with the development of stroke. We report the case of a 68-year-old woman with a past medical history significant for repetitive atrial tachycardia and methylenetetrahydrofolate reductase mutation who presented to an outside emergency department following a fall, weakness and associated aphasia while in atrial fibrillation. Thrombolysis and control of the patient’s rhythm resulted in an initial improvement in the patient symptoms and reversal to normal sinus rhythm. She was subsequently referred to a tertiary stroke center for further management.
