Background: Atrial fibrillation (AF) and heart failure (HF) frequently coexist can be challenging to treat. Pharmacologically based rhythm control of AF has not proven superior rate control. Ablation-based was compared with evaluate if clinical outcomes in patients HF could improved. Methods: This a multicenter, open-label trial blinded outcome evaluation using central adjudication committee. Patients high-burden paroxysmal (>4 episodes 6 months) or persistent (duration <3 years) AF,...
Background: Radiofrequency catheter ablation for atrial fibrillation has become an important therapy AF; however, recurrence rates remain high. We proposed to determine whether aggressive blood pressure (BP) lowering prevents recurrent (AF) after in patients with AF and a high symptom burden. Methods: randomly assigned 184 BP >130/80 mm Hg (target <120/80 Hg) or standard <140/90 treatment before their scheduled ablation. The primary outcome was symptomatic of AF/atrial...
Aims Predictors of recurrence following transcatheter cryoablation for atrioventricular nodal reentrant tachycardia (AVNRT) are currently unknown. Our objective was to explore predictors post-cryoablation AVNRT, including the impact procedural endpoints such as complete elimination slow pathway conduction vs. persistent dual (AV) physiology with or without echo beats.
Background: Cardiac resynchronization therapy (CRT) has been shown to improve symptoms of patients with moderate severe heart failure. Optimal CRT involves biventricular or left ventricular (LV) stimulation alone, atrio‐ventricular (AV) delay optimization, and possibly interventricular timing adjustment. Recently, anodal capture the right ventricle (RV) described for CRT‐pacemakers. It is unknown whether same phenomenon exists in systems associated defibrillators (CRT‐ICD). The RV leads used...
Cardiac resynchronization therapy (CRT) is a mainstay in the treatment of heart failure with severe left ventricular dysfunction, especially presence bundle branch block (LBBB). Biventricular pacing demonstrated notable results improving prognosis and quality life these patients1,2, but its implantation strictly dependent on favorable cardiac venous anatomy to allow delivery lead into coronary sinus (CS). Persistent superior vena cava (LSVC) most common congenital thoracic anomaly,...
Clinically important perioperative atrial fibrillation (POAF) is a common cardiac complication after noncardiac surgery. Little known about how patients with POAF are managed acutely and whether practices have changed over time.
Abstract Background Catheter ablation is an established therapy for atrial fibrillation but limited by recurrence; efforts have been made to identify biomarkers that predict recurrence. We investigated the effect of baseline NT-proBNP on AF recurrence following catheter in patients randomized aggressive (< 120/80 mmHg) or standard blood pressure management 140/90 Substrate Modification with Aggressive Blood Pressure Control trial (SMAC-AF). Methods The SMAC-AF study included 173 resistant...
Key Teaching Points•When a pacemaker fails to record ventricular high-rate (VHR) event, true vs functional undersensing should be considered.•True refers failure detect VHR event owing small-amplitude intrinsic signals or the nature of sensing algorithm.•Functional occurs if episode meet definition is not detected as result way in which refractory blanking periods are programmed.•Functional sustained tachycardia can occur with Biotronik pacemakers rate exceeds 240 beats per minute fact that...
