The use of fluoroscopy is accompanied by significant radiation risks to the patient and the medical staff. Herein, we report our experience in performing successful nonfluoroscopic pulmonary vein isolation using cryoballoon ablation in 5 consecutive patients with paroxysmal atrial fibrillation. Five consecutive patients with paroxysmal atrial fibrillation underwent cryoballoon ablation for pulmonary vein isolation using a nonfluoroscopic approach. Pre-procedural cardiac computed tomography or cardiac magnetic resonance imaging was not performed in any patient. A total of twenty pulmonary veins were identified and successfully isolated (100%) with the guidance of intracardiac echocardiography and 3-dimensional electroanatomic mapping. No fluoroscopy was used for the procedures. There were no major procedural adverse events. In an unselected group of patients und...

We have developed techniques to eliminate the use of fluoroscopy during cardiac ablations and have been performing completely fluoroless catheter ablations on our patients for over 5 years. We present a retrospective analysis of the safety, efficacy, and feasibility data from 500 consecutive patients who underwent nonfluoroscopic catheter ablation, targeting a total of 639 arrhythmias, including atrioventricular reciprocating tachycardia (AVRT), atrioventricular nodal reentrant tachycardia (AVNRT), atrial tachycardia (AT), atrial fibrillation (AF), premature ventricular contractions (PVC), and ventricular tachycardia (VT). We perform fluoroless ablations utilizing intracardiac electrograms (IE), electroanatomic mapping (EAM) and for most cases intracardiac echocardiography (ICE). Our experience includes exclusively endoca...

She was tachycardic and volume overloaded on examination. ECG showed biatrial enlargement with non-specific ST-T changes. D-Dimer, troponin and BNP were elevated. Echocardiogram revealed ejection fraction (EF) <25%, left ventricle (LV) apical ballooning, dyskinetic apex with ballooning of the right ventricle (RV) and elevated RV pressure of 50e60 mmHg. Patient had a left and right coronary angiogram that showed mild non-obstructive coronary artery disease and mild pulmonary hypertension with elevated wedge pressure. Symptoms resolved with medical management and repeat echocardiogram in 3 days showed improved LV EF of 45% and cardiac MRI on day 7 showed normal EF and normal LV and RV wall motion with no evidence of myocarditis.

Research paper thumbnail of Dissemination of a simulation-based mastery learning intervention reduces central line-associated bloodstream infections

We previously developed a simulation-based mastery learning (SBML) curriculum in central venous catheter (CVC) insertion that significantly reduced CLABSI rates. In this study, we evaluated the effect of dissemination of the SBML curriculum on trainee skills and CLABSI rates at a community hospital. The authors performed a cohort study of residents who rotated in the intensive care unit (ICU) at Mercy Hospital and Medical Center from September 2010 to May 2012. Residents underwent an SBML CVC insertion curriculum and were required to meet or exceed a minimum passing score on a simulated internal jugular (IJ) and subclavian (SC) CVC insertion before ICU patient care. Infection control personnel measured CLABSI rates in the ICU before and after the educational intervention. Residents scored a mean IJ pretest of 35.5% (10.29/29, SD=8.30) compared with a post-test mean of 93.0% (...
