Incidence of left atrial appendage thrombus despite 3 weeks of anticoagulation and the need for precardioversion echocardiography.

BACKGROUND: One of the most catastrophic complications of Atrial fibrillation (AF) is thromboembolic stroke. Current guidelines recommend that 3 weeks of anticoagulation is adequate prior to direct current cardioversion (DCCV) to prevent thromboembolism. Here we present data regarding, which anticoagulant is most likely to show a presence of an Left atrial appendage thrombus (LAAT) on trans esophageal echocardiogram (TEE) for DCCV despite 3 weeks of anticoagulation. OBJECTIVE: To investigate the effectiveness of both vitamin k antagonist (VKA) and direct oral anticoagulants (DOAC) in patients with AF as an anticoagulant for LAAT after 3 weeks of medication. METHODS: This is a single-high volume tertiary center, where TEE precardioversion is the standard practice. We reviewed data over 10 months where DCCV was intended on individuals with AF who were fully anticoagulated for at least 3 weeks with either a VKA or taking a DOAC. RESULTS: The data showed a statistical difference between patients who were fully anticoagulated for at least 3 weeks with VKA in comparison to DOACs. Patients on DOACs are significantly less likely to have an LAAT after at least 3 weeks of anticoagulation. OR = 0.04 (CI 95% 0.005-0.42; p-value < .05). Despite anticoagulation for at least 3 weeks, 40% of our patients still had a LAAT. CONCLUSION: Our data indicates that all patients should be required to undergo a TEE prior to DCCV. This data also adds to the current evidence and supports the use of DOAC in AF to prevent LAAT.

Congenital epignathus associated with a cleft palate: a case report.

BACKGROUND: Epignathus is a rare, benign, congenital teratoma of the hard palate with an estimated incidence of 1 in 200,000 live births. Epignathus frequently leads to a high mortality (80-100%) due to airway obstruction in the neonatal period. CASE PRESENTATION: We report a case of successful management of a rare oropharyngeal teratoma in a African newborn girl who was referred to our institute with a large protruding intraoral mass, combined with cleft palate, causing some respiratory compromise. The palatal mass was removed on the fifth day after birth, and a palatoplasty performed on day 30. CONCLUSION: Epignathus is a life-threatening condition at the time of delivery. Appropriate management begins with securing the airway, followed by complete resection of the tumor.

Effects of Holding Beta-Blockers on the Vital Signs of Heart Failure Patients.

BACKGROUND: Heart failure with reduced ejection fraction (HFrEF) is associated with recurrent hospitalizations and high mortality. Guideline-directed medical therapy (GDMT) reduces morbidity, mortality and re-admission rates. Despite the evidence, less than 50% of patients with HFrEF are prescribed appropriate medical therapy. When hospitalized patients have these medications discontinued on admission or during hospitalization, they are less likely to have them restarted on discharge. The goal of this study was to determine the incidence of disruption of beta-blocker (BB) therapy during hospitalization for HFrEF patients admitted to an academic tertiary referral hospital. METHODS: We conducted a retrospective study in a single teaching hospital over the course of 1 year, and utilized data queried from the electronic medical record (EPIC) database. Inclusion criteria were met by patients with an ICD-10 code diagnosis of heart failure, left ventricular ejection fraction less than 40% and BB prescription prior to admission. Additional information noted included age, sex, vital signs throughout the admission and dates where BB was not given for a full 24-h period. Patients in the intensive care unit (ICU) were excluded due to uncertainty of their hemodynamics. Data were extracted from the electronic medical record database and analyzed through Python, Microsoft Excel and RStudio. The incidence of BB disruption during hospitalization was defined as a 24-h period where no BB was administered. Blood pressure (BP) and heart rate (HR) levels were compared between patients who received BB and patients who had a disruption in their BB. Measurements were also obtained to assess whether a correlation exists between holding BB therapy and time of the year, age, or sex. RESULTS: Between January 2018 and January 2019, 780 patient encounters met inclusion criteria for the study. Patients who were continued on BB therapy had an average BP of 120.8/68.7 mm Hg and an HR of 82.4 bpm on days they received their BB. Patients who had a disruption of BB therapy had an average BP of 117.7/67.6 mm Hg and an HR of 88.6 bpm on the days of the disruption (P < 0.001). There was no association between holding BB and age, sex, or time of year. CONCLUSIONS: This study showed that in an academic tertiary referral center, patients with HFrEF who are not in an ICU have a 23% chance of not receiving their recommended BB therapy for 24 h. While the differences measured for BP and HR are statistically significant, they are not clinically significant.

Thyroid and Cardiovascular Disease: A Focused Review on the Impact of Hyperthyroidism in Heart Failure.

The association between thyroid hormones and cardiovascular conditions has been well studied, specifically, the effects of hypothyroidism on cardiomyopathy, and hyperthyroidism with arrhythmias. Nonetheless, an explicit correlation between hyperthyroidism and cardiomyopathy has yet to be established. Medical databases MEDLINE and PubMed were accessed and queried as primary sources for data acquisition. Search criteria consisted of "hyperthyroidism", "heart failure", and "thyroid and cardiovascular system", which allowed the retrieval of relevant and recent works. From these sources, a consensus was developed and employed to yield an updated review of the etiology of heart failure in the setting of hyperthyroidism. It is rare for patients with hyperthyroidism to remain in a chronic hyperthyroid state, making it difficult to analyze subsequent long-term effects on the cardiovascular system. Related to heart failure, some studies have demonstrated no change in ejection fraction, while others have shown an acute change along with diastolic dysfunction, with or without an underlying rhythm abnormality. Further investigation is warranted to elucidate the mechanism driving such cardiac dysfunction, and whether it is due to vascular changes, tachyarrhythmias, or myocyte remodeling and fibrosis. The intent of this review article is to improve our understanding of how a hyperthyroid state affects cardiovascular function. An enhanced understanding of the effects on cardiovascular physiology will afford physicians the ability to provide more comprehensive care in consideration of both endocrine and cardiovascular pathologies.

Candida dubliniensis abscess: A clinical case and a review of the literature.

Candida dubliniensis infections are rare in the absence of prolonged immunocompromised status or intravenous drug abuse. We present a case of a C. dubliniensis soft tissue abscess in a patient with uncontrolled diabetes as his only immunocompromising risk factor, treated with surgical drainage and medical management.
