A PVI-only strategy in PeAF patients with a low prevalence of structural heart disease using contemporary technology yields excellent outcomes comparable to those for paroxysmal AF ablation.

Aims: Obesity is associated with higher electrical cardioversion (ECV) failure in persistent atrial fibrillation (PeAF). For ease-of-use, many centers prefer patches over paddles. We assessed the optimum modality and shock vector, as well as the safety and efficacy of the Manual Pressure Augmentation (MPA) technique. Methods: Patients with obesity (BMI ≥ 30) and PeAF undergoing ECV using a biphasic defibrillator were randomized into one of four arms by modality (adhesive patches or handheld paddles) and shock vector (anteroposterior [AP] or anteroapical [AA]). If the first two shocks (100 and 200 J) failed, then patients received a 200-J shock using the alternative modality (patch or paddle). Shock vector remained unchanged. In an observational substudy, 20 patients with BMI of 35 or more, and who failed ECV at 200 J using both patches/paddles underwent a trial of MPA.Results: In total, 125 patients were randomized between July 2016 and March 2018. First or second shock success was 43 of 63 (68.2%) for patches and 56 of 62 (90.3%) for paddles (P = 0.002). There were 20 crossovers from patches to paddles (12 of 20 third shock success with paddles) and six crossovers from paddles to patches (three of six third shock success with patches). Paddles successfully cardioverted 68 of 82 patients compared with 46 of 69 using patches (82.9% vs 66.7%; P = 0.02). Shock vector did not influence first or second shock success rates (82.0% AP vs 76.6% AA; P = 0.46). MPA was successful in 16 of 20 (80%) who failed in both (patches/paddles), with 360 J required in six of seven cases.

Introduction: To determine the prevalence, severity, and change in symptoms experienced by dialysis patients following the introduction of use of a symptom-reporting questionnaire in nephrology clinic. Methods: This is an observational study of 160 prevalent dialysis patients. Palliative care Outcome Scale symptom (POS-renal) questionnaires modified for patients with end-stage kidney disease were completed at baseline and follow-up (median 3 months), with results available to nephrologists at clinic appointments. Findings: The baseline prevalence of individual symptoms ranged from 15% to 66%. The most common symptoms were lack of energy (66%) and poor mobility (58%). The median number of symptoms was 7/17 (interquartile range [IQR]: 4-10). Forty-nine percent of patients rated at least 1 symptom as severe or overwhelming. At follow-up, the median number of symptoms experienced was unchanged at 7/17 (IQR: 3-10). However, there was considerable flux in symptom severity. On average, individual symptoms that were present at baseline improved in 56% of patients and worsened in 18%; only 26% had stable symptom severity. Individual symptoms newly occurred in 8% to 20% of patients between time points, with 77% of patients experiencing at least 1 new symptom. The percent of patients rating at least 1 symptom as severe or overwhelming was reduced from 49% to 39% ( P = .040). Conclusions: Use of the POS-renal questionnaire identified a high symptom burden. The presence and severity of symptoms changed dramatically over a short follow-up period, highlighting the need for regular surveillance of symptoms in the dialysis population. Routine use of a symptom questionnaire in clinic may be useful for the identification and management of symptoms in dialysis patients.
