Meningococcal myocarditis is a rarely diagnosed infection and could be the consequence of primary invasive infection or late immunologic complications. An unusual presentation of meningococcemia in an immunocompetent adult is described, with Neisseria meningitidis identified as the cause of selective right-sided heart failure in a case of acute myocarditis.

Introduction: Moderate to severe tricuspid regurgitation (TR) in the setting of acute heart failure (AHF) has been found to be associated with worse clinical outcomes. Recently, the TRI-SCORE was developed to predict clinical outcomes after isolated tricuspid surgery.
Objectives: To determine whether this score could aid in risk stratification of AHF patients with moderate-severe TR.

Background: Desmoplakin (DSP) variants are associated with left-predominant or biventricular arrhythmogenic cardiomyopathy. Exercise promotes penetrance and sustained ventricular arrhythmias (VA) in right-sided arrhythmogenic right ventricular cardiomyopathy, but its effect is unknown in DSP variant carriers.
Objectives: To assess whether exercise is associated with clinical outcomes among individuals with a pathogenic or likely pathogenic (P/LP) DSP variant.

Atrial fibrillation (AF), the most prevalent sustained cardiac arrhythmia, is intricately linked with atrial functional tricuspid regurgitation (AFTR), a condition distinguished from ventricular functional tricuspid regurgitation by its unique pathophysiological mechanisms and clinical implications. This review article delves into the multifaceted aspects of AFTR, exploring its epidemiology, pathophysiology, diagnostic evaluation, and management strategies. Further, we elucidate the mechanisms underlying AFTR, including tricuspid annular dilatation, right atrial enlargement, and dysfunction, which collectively contribute to the development of tricuspid regurgitation in the absence of significant pulmonary hypertension or left-sided heart disease.

Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.

Background: Concurrent ST-elevation myocardial infarction (STEMI) and acute ischemic stroke (AIS) are extremely rare, and their management remains perplexing due to the absence of high-quality evidence and limited resources. For the first time, we report a rare, preventable, and suboptimally managed case of concurrent AIS and STEMI in a patient with non-Hodgkin lymphoma (NHL) who received cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) chemotherapy.
Case Presentation: A 59-year-old postmenopausal woman of African origin with a background history of type 2 diabetes mellitus presented to the Jakaya Kikwete Cardiac Institute with sudden onset of left-sided weakness and typical ischemic chest pain for 3 days.
