Subacute Multivalvular Bacterial Endocarditis Complicated by Ruptured Mycotic Aneurysm and the Impact of Gender on Early Surgical Intervention.

Subacute bacterial endocarditis (SBE) evolves over weeks to months, often without typical features of acute endocarditis. Its presentation progresses gradually until possibly complicated by sentinel events, such as a cerebrovascular accident from embolization or a ruptured vessel. This is a case of SBE presenting as symptomatic anemia in a female patient with severe aortic regurgitation (AR) and mitral regurgitation (MR) due to bi-valvular vegetations in the absence of typical acute endocarditis and congestive heart failure (CHF) features.

GPR75: A Newly Identified Receptor for Targeted Intervention in the Treatment of Obesity and Metabolic Syndrome.

Metabolic syndrome increases the risk of stroke, cardiovascular disease, and diabetes. The morbidity and mortality associated with this constellation of risk factors are equally alarming when considering the economic and global significance that this epidemic has on an institutional and patient level. Despite several current treatments available, there needs to be a continuous effort to explore more specific and effective druggable entities for preventative and therapeutic interventions. Within this context, the G-protein coupled receptor, GPR75, is an attractive pharmacological target. GPR75 and its association with its ligand, 20-hydroxyeicosatetraenoic acid, have been shown to promote hypertension, inflammation, obesity, and insulin resistance. This review will help shed light on this novel signaling pathway and offer a perspective on a promising new direction of targeting different aspects of the metabolic syndrome involving GPR75. Gene targeting of GPR75 is more effective than current pharmacologic therapies without the known side effects.

Gender Differences in the Evaluation and Management of New Acute CHF Due to ATTRwt Cardiac Amyloidosis.

Cardiac amyloidosis can be grouped into two main categories: immunoglobulin light chain (AL) and transthyretin (hATTR or hereditary and ATTRwt or wild type). Cardiac infiltration of misfolded proteins can lead to significant infiltrative processes and subsequent heart failure. Diagnosis of ATTRwt heavily relies on clinical suspicion, as it typically appears later in life and is limited to the heart. It is routinely reported that ATTRwt significantly affects males more than females; however, older patients diagnosed with ATTRwt and those diagnosed at autopsy are significantly more likely to be female. Earlier, a more precise diagnosis in females could detect disease at an earlier stage and expedite treatment.

A Late Presentation of Right Common Iliac Vein Stent Embolization to the Right Atrium: Important Management Considerations.

Stent migration is a rare but serious complication of venous stenting, often presenting with chest pain, shortness of breath, and signs of heart failure. Potential complications include arrhythmia, perforation, and valve destruction. Here we present an asymptomatic patient with a late presentation of right common iliac vein stent migration to the right atrium.

Native Aortic Valve Endocarditis Secondary to Gastric Antral Vascular Ectasia Manipulation During Endoscopic Argon Plasma Coagulation.

Gastric antral vascular ectasia (GAVE) is an uncommon cause of upper gastrointestinal (GI) bleeds. Due to the high vascularity of the region, transient bacteremia due to manipulation of the GI tract can very rarely cause the translocation of bacteria. We present a rare case in which endoscopic manipulation to treat GAVE led to native valve infective endocarditis (IE). Our patient had a prior history of GAVE and presented with worsening dizziness and shortness of breath (SOB). After an esophagogastroduodenoscopy (EGD) and subsequent argon plasma coagulation (APC) for active preantral bleeding, the patient was noted to have repeated fevers, a new cardiac murmur, and positive blood cultures for Staphylococcus epidermidis, leading to a diagnosis of native infective endocarditis. With high clinical suspicion and early recognition of a new cardiac murmur, a transesophageal echocardiogram (TEE) was key in identifying vegetation. This case highlights the importance of combining history, a physical exam, and diagnostic lab tests and imaging to identify endocarditis. Management included two months of intravenous (IV) vancomycin and repeat TEE for close monitoring of vegetation improvement.

Time is Blood: The Impact of Diagnostic Delays on Acquired Hemophilia A.

Background and objective Acquired hemophilia A (AHA) is an uncommon autoimmune bleeding disorder caused by the formation of neutralizing antibodies against endogenous factor VIII (FVIII). Delays between the onset of symptoms and the correct diagnosis of the condition lead to poor outcomes and a higher mortality rate. In this study, we aimed to analyze the impact of delays in diagnosis on AHA patients. Methods We conducted a retrospective study at a single hospital system between March 1, 2010, and January 17, 2017, which included six patients meeting the criteria for AHA diagnosis. Results Initial analysis revealed a median age of 79.5 years and a median time to diagnosis from the onset of bleeding of 14 days. Among the six patients, three had cancer (bladder, renal, and prostate) and three had unknown etiologies. One of the patients died prior to the initiation of a bypassing agent. The remaining five patients received recombinant FVIIa (NovoSeven®, Novo Nordisk, Bagsværd, Denmark), and two of those five required a second-line bypassing agent, recombinant porcine sequence FVIII (Obizur®, Takeda Pharmaceutical, Tokyo, Japan) for refractory bleeding. All five patients achieved hemostasis; however, three died within a year, and none of the patients survived for five years. Four of these five patients died directly from bleeding complications. Conclusions Based on our study findings and review of the literature, we propose an algorithm to potentially aid in the early diagnosis and treatment of AHA in emergency and non-specialized settings.
