Background-Brain natriuretic peptide (BNP) is useful in diagnosing congestive heart failure (CHF) in patients presenting in the emergency department with acute dyspnea. We prospectively tested the utility of BNP for discriminating ARDS vs cardiogenic pulmonary edema (CPE).

As the volume and complexity of catheter ablation of atrial fibrillation (AF) continue to rise, there is increasing attention directed at reducing exposure to ionizing radiation. This has led to the emergence of intracardiac echocardiography (ICE) as a stand-alone imaging modality guiding AF ablation. In addition to directing transseptal puncture, ICE may be used to identify left atrial structures and to guide the manipulation of catheters. ICE may also be used to visualize the esophagus in real-time and to assist with early identification of procedural complications. This review provides detailed step-by-step directions for identification of relevant structures and summarizes the use of ICE during AF ablation.

Among 'real world' patients treated with SES, the incidence of TLR and MACE at 1 year was substantially greater among SIRIUS ineligible patients compared with SIRIUS eligible patients. These findings confirm that pivotal clinical trials of drug-eluting stents tend to enroll low-risk patients and that the estimated rates of TLR and MACE derived from such trials may not reflect subsequent outcomes with unrestricted clinical use.
