Atrial fibrillation future clinic. Novel platform to integrate smart device electrocardiogram into clinical practice.

Background: Direct-to-consumer devices allow patients to record electrocardiograms (ECG) and detect atrial fibrillation (AF). Clinical adoption of these devices has been limited owing to the lack of efficient workflow.

Objective: To assess a new care model for following patients after AF ablation that uses a smartphone ECG coupled with a novel cloud-based platform.

Management and outcomes in mitral valve prolapse with ventricular arrhythmias undergoing ablation and/or implantation of ICDs.

Background: While there is an association between isolated mitral valve prolapse (MVP) and sudden cardiac arrest (SCA), the baseline characteristics and outcomes of patients with isolated MVP who experience ventricular arrhythmias (VAs) and then subsequently undergo catheter ablation and/or implantable cardioverter defibrillator (ICD) implantation are unknown.

Methods: We performed a retrospective review of all patients at the Cleveland Clinic with isolated MVP between 1997 and 2016 who underwent VA catheter ablation or secondary prevention ICD implantation.

Results: Of 617 screened patients, we identified 43 patients with isolated MVP and significant VA who underwent ICD placement (n = 13, 30%) or catheter ablation (n = 30, 70%).

Smartwatch Algorithm for Automated Detection of Atrial Fibrillation.

Background: The Kardia Band (KB) is a novel technology that enables patients to record a rhythm strip using an Apple Watch (Apple, Cupertino, California). The band is paired with an app providing automated detection of atrial fibrillation (AF).

Objectives: The purpose of this study was to examine whether the KB could accurately differentiate sinus rhythm (SR) from AF compared with physician-interpreted 12-lead electrocardiograms (ECGs) and KB recordings.

Relation of pulse and systolic and mean blood pressure to severe renal artery stenosis in patients undergoing concurrent coronary and renal angiography.

Abrupt onset of renal ischemia is associated with increased blood pressure (BP), but it is unknown whether BP remains elevated in patients with chronic severe atherosclerotic renal artery stenosis (RAS). Patients undergoing coronary angiography who had concurrent renal angiography were divided into 3 groups: severe (stenosis ≥70% diameter reduction), moderate (10%-69%), and minimal RAS. Aortic BP was measured at the time of angiography.

Simultaneous occurrence of a single coronary artery and persistent left superior vena cava.

We present a case of simultaneous occurrence of 2 rare congenital anomalies. A 57-year-old woman undergoing evaluation of dyspnea was found to have a single coronary artery and persistent left superior vena cava. The incidence of single coronary artery is 0.
