A Systematic Review of COVID-19 and Pericarditis.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in Wuhan, China in December 2019. Since then, the disease has spread globally, leading to the ongoing pandemic. It can cause severe respiratory illness; however, many cases of pericarditis have also been reported. This systematic review aims to recognize the clinical features of pericarditis and myopericarditis in COVID-19 patients. Google Scholar, Medline/PubMed, CINAHL, Cochrane Central, and Web of Science databases were searched for studies reporting "Coronavirus" or "COVID" and "Peri-myocarditis," "heart," or "retrospective." Case reports and retrospective studies published from May 2020 to February 2021 were reviewed. In total, 33 studies on pericarditis, myopericarditis, and pericardial infusion were included in this review. COVID-19 pericarditis affected adult patients at any age. The incidence is more common in males, with a male-to-female ratio of 2:1. Chest pain (60%), fever (51%), and shortness of breath (51%) were the most reported symptoms, followed by cough (39%), fatigue (15%), myalgia (12%), and diarrhea (12%). Laboratory tests revealed leukocytosis with neutrophil predominance, elevated D-dimer, erythrocyte rate, and C-reactive protein. Cardiac markers including troponin-1, troponin-T, and brain natriuretic peptide were elevated in most cases. Radiographic imaging of the chest were mostly normal, and only 31% of chest X-rays showed cardiomegaly and or bilateral infiltration. Electrocardiography (ECG) demonstrated normal sinus rhythm with around 59% ST elevation and rarely PR depression or T wave inversion, while the predominant echocardiographic feature was pericardial effusion. Management with colchicine was favored in most cases, followed by non-steroidal anti-inflammatory drugs (NSAIDs), and interventional therapy was only needed when patient developed cardiac tamponade. The majority of the reviewed studies reported either recovery or no continued clinical deterioration. The prevalence of COVID-19-related cardiac diseases is high, and pericarditis is a known extrapulmonary manifestation. However, pericardial effusion and cardiac tamponade are less prevalent and may require urgent intervention to prevent mortality. Pericarditis should be considered in patients with chest pain, ST elevation on ECG, a normal coronary angiogram, and COVID-19. We emphasize the importance of clinical examination, ECG, and echocardiogram for decision-making, and NSAIDs, colchicine, and corticosteroids are considered to be safe in the treatment of pericarditis/myopericarditis associated with COVID-19.

An observational study of the management practices and outcomes of patients with new onset atrial fibrillation in non-cardiothoracic surgeries.

BACKGROUND AND OBJECTIVE: Limited data exist on characteristics and management of patients with postoperative atrial fibrillation (POAF) after noncardiothoracic surgeries and on the relationship between symptoms and outcomes. We sought to describe clinical features, in-hospital practices and outcomes in patients with new POAF by the presence or absence of clinical symptoms. METHODS: Retrospective cohort study of adults with POAF in one tertiary center. RESULTS: Among the 99 patients who fulfilled the eligibility criteria, median age was 75 years (IQR 64-83) and 57.6% were male. Only thirty percent of patients with POAF were symptomatic. Rate control/conversion to sinus rhythm was achieved in ≤ 4 h in 56% of the patients and in 80% was maintained for ≥ 24 h. Anticoagulation was prescribed in 50% of those discharged in AF; the CHADS2-VASc score was not associated with anticoagulation prescribed. One third of patients were readmitted and half of them were in AF. Asymptomatic patients had lower median heart rate than symptomatic patients but no other clinical characteristics, or outcomes were different. CONCLUSIONS: Most patients with POAF were asymptomatic but their presentation or outcomes were similar with symptomatic patients. One in four discharged patients was prescribed anticoagulation and the CHADS2-VASC score was not associated with this decision. These findings have important implications for practice and future research. There is a need to better delineate the risk associated with transient versus persistent POAF, symptomatic versus asymptomatic POAF, as well as for clinical trials to determine optimal strategies to improve their outcomes.

Bilateral Bilothorax: An Unusual Cause of Bilateral Exudative Pleural Effusion.

Bilothorax is an uncommon cause of exudative pleural effusion; the majority of reported cases are right-sided while a bilateral presentation is extremely rare. The majority of cases are secondary to biliary obstruction, an extension of hepatic infections, and iatrogenic complications following percutaneous procedures or surgical interventions. Imaging studies and a diagnostic pleural tap can confirm the diagnosis. Early recognition and complete drainage are important to prevent life-threatening complications, including empyema formation. We present a case of a 71-year-old female who developed bilateral bilothorax as a complication of gallstone pancreatitis.
