Long-Term Outcomes of Cardiac Sarcoid: Prognostic Implications of Isolated Cardiac Involvement and Impact of Diagnostic Delays.

Background Isolated cardiac sarcoid (iCS) is reported to have more severe clinical presentation and greater risk of adverse events compared with cardiac sarcoid (CS) with extracardiac involvement (nonisolated CS). Delays in diagnosing specific organ involvement may play a role in these described differences. Methods and Results A retrospective observational study of patients with CS over a 20-year period was conducted.

Esophageal temperature management during cryoballoon ablation for atrial fibrillation.

Introduction: Esophageal thermal injury (ETI) is a well-recognized complication of atrial fibrillation (AF) ablation. Previous studies have demonstrated that direct esophageal cooling reduces ETI during radiofrequency AF ablation. The purpose of this study was to evaluate the use of an esophageal warming device to prevent ETI during cryoballoon ablation (CBA) for AF.

The effect of catheter ablation for ventricular arrhythmias originating from the left ventricular papillary muscles on mitral valve function.

Background: Ablation of ventricular arrhythmias (VA) originating from the left ventricular (LV) papillary muscles (PM) has the potential to damage the mitral valve apparatus resulting in mitral regurgitation (MR). This study sought to evaluate the effect of radiofrequency (RF) ablation of a PM on MR severity.

Methods: Patients with pre- and postablation transthoracic echocardiograms who underwent PM ablation for treatment of VA were retrospectively identified and compared to similar patients who underwent VA ablation at non-PM sites.

A novel telemedicine technique for evaluation of ocular exam findings via smartphone images.

In this study, we compared the assessment of remote smartphone photographs to in-office exams in the diagnosis of two groups of external eye diseases, red-eye pathology and post-operative eyelid surgery complications. Participants were examined and received an in-office diagnosis by either a corneal or oculoplastic specialist. After viewing an educational video on smartphone photography, the patient's companion then took a series of standardized photographs.
