Low Voltage-Guided Ablation Of Posterior Wall Improves 5-Year Arrhythmia-Free Survival In Persistent Atrial Fibrillation, Ahmad Jabri, Soufian T. Almahameed, Ohad Ziv

Faculty Scholarship

Introduction: The posterior wall (PW) has been proposed as a standard target for ablation beyond pulmonary vein antral isolation (PVI) in patients with persistent atrial fibrillation (AF). However, studies have shown inconsistent outcomes with the addition of PW ablation. The presence or absence of low voltage on the PW may explain these inconsistencies. We evaluated whether PW ablation based on the presence or absence of low voltage improves long-term arrhythmia-free outcomes. Methods: We retrospectively reviewed 5-year follow-up in 152 consecutive patients who received either standard ablation (SA) with PVI alone or PVI + PW ablation (PWA) based on physician discretion …

The coronavirus disease 2019 (COVID-19) has overwhelming healthcare systems globally. To date, a myriad of therapeutic regimens has been employed in an attempt to curb the ramifications of a severe COVID-19 infection. Amidst the ongoing pandemic, the advent and efficacious uptake of COVID-19 vaccination has significantly reduced disease-related hospitalizations and mortality. Nevertheless, many side-effects are being reported after COVID-19 vaccinations and myocarditis is the most commonly reported sequelae post vaccination. Majority of these diseases are associated with COVID-19 mRNA vaccines. Various studies have established a temporal relationship between these complications, yet the causality and the underlying pathogenesis remain hypothetical. In …

Management Of Hyperkalemia To Prevent Cardiac Arrest, Jennifer Harklerode, Amber Paul, Crystal Zheng, Olivia Vanscoy, Olivia Henton, Mark Olah

Pharmacy and Wellness Review

Hyperkalemia is a metabolic problem that may be life threatening if left untreated. Cardiac arrhythmias may develop with the potential to lead to cardiac arrest and death. Hyperkalemia can oftentimes be undiagnosed due to the lack of clear, specific symptoms and inconclusive variations in electrocardiogram (ECG) readings and lab values. Therefore, it is important to recognize risk factors that can potentially in-crease serum potassium levels. Screening for medications that increase serum potassium levels and educating patients are steps that both inpatient and outpatient health care professionals can take to increase early detection and prevention of a hyperkalemic episode. It is …

Isolated Right Superior Vena Cava Drained To Left Atrium In A Child With Waardenburg Syndrome And Neurofibromatosis Type I, Omer A. Algonaid, Yahya H. Almashham, Abdulrahman S. Almoukirish

Journal of the Saudi Heart Association

Isolated right superior vena cava (SVC) draining to the left atrium (RSVC-LA) is an extremely rare cyanotic congenital heart disease (CHD). Such lesion is easily missed with improper scanning or inattentive interpretation of echocardiography. This can result in potential systemic severe complications. We report a child with RSVC-LA who has two significant non-cardiac co-morbidities, including Waardenburg syndrome and n neurofibromatosis type I (NF1). This patient was referred to cardiology assessment due to unexplained low saturation and was diagnosed as RSVC-LA; however, fortunately not yet showing complications of systemic thromboembolic phenomenon (STEP).
