Background: ECG interpretation is crucial in medical practice, but professionals struggle with achieving and maintaining competency. Identifying proficiency gaps aids in designing educational interventions. Methods: Medical professionals from various disciplines interpreted 30 12-lead ECGs containing commonly taught urgent and non-urgent findings. Performance metrics evaluated were overall adjusted score (% of correctly identified findings using a point-value score based on clinical relevance), unadjusted score (% of correctly identified findings), interpretation time per ECG, and self-reported confidence (rated on an ordinal scale of 0 [not confident], 1 [somewhat confident], or 2 [confident]). Results: Among 1206 participants, there were 72 (6%) primary care physicians (PCPs), 146 (12%) cardiology fellows-in-training (FIT), 353 (29%) resident physicians, 182 (15%) medical students, 84 (7%) advanced practice providers (APPs), 120 (10%) nurses, 249 (21%) allied health professionals, 571 (47%) physicians, and 453 (38%) non-physicians. Participants had a mean adjusted score of 46.9% (± 15.9%), unadjusted score of 56.4% (± 17.2%), interpretation time of 142 seconds (± 67 seconds), and confidence of 0.83 (± 0.53) (Table 1) . Performance varied across groups; cardiology FIT had superior performance in all metrics. Physicians generally outperformed non-physicians, with higher overall adjusted score (52% vs. 43%; p<0.01), unadjusted score (62% vs. 52%; p<0.01), and confidence (0.91 vs. 0.80; p<0.01). Unadjusted score for PCPs was higher than nurses and APPs (58% vs. 47% and 51%; p<0.01) but lower than resident physicians (58% vs. 60%; p<0.01). Allied health professionals outperformed nurses and APPs and closely matched resident physicians and PCPs. Conclusions: Significant gaps in ECG interpretation proficiency exist, emphasizing the need for comprehensive, scalable, and accessible educational tools.

Purpose: New 2022 European Society of Cardiology/European Respiratory Society PAH guidelines recommend treatment guided by a multi-parameter risk assessment. 1 Patients with low/intermediate risk without cardiopulmonary comorbidities should start dual PAH combination therapy; those with cardiopulmonary comorbidities should be reassessed early for rapid escalation to dual therapy. Initial triple therapy is recommended for high-risk patients. We examined use of dual and triple PAH therapy in the US (before guideline update). Methods: We used the Pulmonary Hypertension Association Registry (PHAR), a prospective US registry of pulmonary hypertension (PH) patients, enrolled within 6 months of their first outpatient visit at one of 54 participating PH care centers in the US, between Sep 2015-Jun 2022. We included adults (≥18 years at enrollment) with incident PAH (newly diagnosed and treated within 6 months of enrollment) and ≥1 follow-up clinic visit post baseline visit. Chronic thromboembolic PH patients were excluded. Results: We analyzed (descriptive statistics) 794 incident patients (baseline characteristics in Table 1). Treatment patterns at baseline (n=794)/last follow-up visit (n=610) were 289 (36.4%)/102 (16.7%) on monotherapy, 419 (52.8%)/314 (51.5%) on dual combination, 83 (10.5%)/179 (29.3%) on triple combination therapy, respectively. Mean time from enrollment to dual and triple combination therapy was 86.1 (standard deviation [SD]: 209.0) and 346.1 days (SD: 430.8), respectively. Conclusions: Among incident PHAR patients, half received initial dual and 10% triple upfront combination therapy. At last follow-up, most (>80%) patients had escalated to dual/triple combination therapies. Clinical Implications: At PH care centers, most incident PHAR patients are escalated to dual and triple therapy (at last follow-up) per current guidelines. Reference 1. Humbert M, et al.

Case: This report describes the case of an athletic 12-year-old boy who presented with a 64° left proximal humeral varus angulation deformity and physeal bar secondary to multiple operations for a proximal humeral metaphyseal cystic lesion and pathologic fracture. Using a combined lateral closing and medial opening-wedge osteotomy, a 68° valgus correction was achieved with excellent clinical and functional outcomes at 16-month follow-up. Forward flexion increased from 120 to 170° preoperatively to postoperatively while abduction improved from 110° preoperatively to 170° postoperatively. Conclusion: A combined lateral closing and medial opening-wedge osteotomy of the proximal humerus can successfully treat cases of extreme proximal humerus varus in the growing shoulder where unilateral or dome osteotomies are not suitable.
