Objective The radiofrequency (RF) needle has been shown to improve transseptal puncture efficiency and safety compared to mechanical needles. This study aimed to investigate the use of VersaCross RF transseptal wire system (Baylis Medical) to improve procedural efficiency of left atrial appendage closure (LAAC) compared to the standard RF needle‐based workflow. Methods Eighty‐one LAAC procedures using WATCHMAN FLX were retrospectively analyzed comparing the standard RF needle‐based workflow to a RF wire‐based workflow. Study primary endpoint was time to WATCHMAN device release, and secondary endpoints were transseptal puncture time, LAAC success, fluoroscopy use, and procedural complications. Results Twenty‐five cases using standard RF needle‐based workflow were compared to 56 cases using the RF wire‐based workflow. Baseline patient characteristics were similar between both groups. LAAC was successful in all patients with no differences in intraprocedural complication rates (p = 0.40). Transseptal puncture time was 1.3 min faster using the RF wire‐based workflow compared to the standard RF needle‐based workflow (6.5 ± 2.3 vs. 7.8 ± 2.3 min, p = 0.02). Overall, time to final WATCHMAN device release was 4.5 min faster with the RF wire‐based workflow compared to the RF needle‐based workflow (24.6 ± 5.6 vs. 29.1 ± 9.6 min, p = 0.01). Fluoroscopy time was 21% lower using the RF wire‐based workflow (7.6 ± 2.8 vs. 9.6 ± 4.4 min; p = 0.05) and fluoroscopy dose was 67% lower (47.1 ± 35.3 vs. 144.9 ± 156.9 mGy, p = 0.04) and more consistent (F‐test, p ˂ 0.0001). Conclusions The RF wire‐based workflow streamlines LAAC procedures, improving LAAC efficiency and safety by reducing fluoroscopy, device exchanges, and delivery sheath manipulation.
A two-phase, single-blinded, non-randomized trial was conducted at MI-based Ascension Providence Hospital with a convenience sample of hypertensive patients. BP readings were taken using both an Omron 907 (Omron Corp., Kyoto, Japan) and a Welch Allyn (WA) Connex Spot Monitor (Welch Allyn, Inc., Skaneateles Falls, NY) AOBP devices. Descriptive statistics were generated, and T-tests were performed. RESULTSIn Phase 1, (N = 148), the mean systolic/diastolic readings for the pre-physician visits (141/82 mmHg) were statistically significantly higher than the post-visit readings (134/80 mmHg) (p ≤ 0.02). Post-visit physician readings from either AOBP device did not differ statistically (p = 0.72). In Phase 2 (n = 50), the presence of an MA resulted in significantly higher readings than when an MA was absent, however, the results of Phase 2 also supported the trends for lower BP post-physician visit found in Phase 1. CONCLUSIONBased on the consistency of these results, a post-physician visit AOBP reading, in the presence or absence of an MA, may provide a more accurate BP measurement to determine whether or not to treat hypertension in African American patients.
Patient: Male, 45-year-old Final Diagnosis: Salmonella dublin pericarditis Symptoms: Chest pain • shortness of breath Clinical Procedure: — Specialty: Cardiology Objective: Rare disease Background: Salmonella infections manifest typically as self-limiting gastroenteritis after the consumption of contaminated food. Extra-intestinal manifestations of Salmonella infections such as pericarditis are rare and are usually seen in severely immunocompromised individuals. Prior case reports suggest high rates of morbidity and mortality associated with Salmonella pericarditis. Here, we present a rare case of Salmonella dublin pericarditis. Case Report: A 45-year-old man presented to the Emergency Department reporting chest pressure and shortness of breath. An echocardiogram showed a large pericardial effusion without tamponade physiology. Pericardial window was performed, with removal of 700 cubic centimeters of bloody fluid, with presence of fibrinous debris in the pericardial cavity. A pericardial biopsy showed chronic pericarditis, and a lymph node biopsy was negative for malignancy. Antinuclear antibody (ANA), Lyme antibodies, and human immunodeficiency virus (HIV) testing were negative. Tissue culture revealed Salmonella species. Subsequent blood cultures grew Salmonella spp . Further history-taking revealed frequent travel and recent treatment with steroids for suspected Bell’s palsy. Initially, the patient was treated with ceftriaxone, which was switched to ciprofloxacin after susceptibility testing revealed ceftriaxone resistance. Final identification of the organism revealed Salmonella dublin . The patient was discharged on colchicine, ibuprofen, and a 4-week course of ciprofloxacin. Outpatient follow-up showed improvement in inflammatory markers and symptoms. Conclusions: This case illustrates the rarity of Salmonella-associated pericarditis, the importance of assessing a patient’s risk factors, and obtaining an extensive history when searching for an etiology of pericarditis. Investigation into why a patient was susceptible to an infection with this organism should include medication assessment and age-appropriate cancer screening. Prompt identification and treatment of the offending organism can help prevent mortality.
