Meta-Analysis of the Outcomes of Peri-Device Leak After Left Atrial Appendage Closure.

Left atrial appendage closure (LAAC) reduces the risk of thromboembolic stroke in atrial fibrillation. Peri-device leak (PDL) after LAAC may affect the subsequent risk of thromboembolism. We conducted a systematic review and meta-analysis to evaluate the effect of PDL after LAAC. We searched PubMed/Medline, Embase, and Google Scholar for studies reporting outcomes of PDL after LAAC from inception through October 2022. The primary outcome was the composite of stroke, transient ischemic attack (TIA), or systemic embolism (SE). Secondary outcomes included all-cause and cardiovascular mortality, ischemic stroke, TIA, and device-related thrombus. Outcomes were pooled using random-effects models. We used I2 statistics to assess statistical heterogeneity; I2 >50% considered significant heterogeneity. This study included 54,279 patients from 11 studies (6 observational, 2 nonrandomized controlled trials [non-RCTs] primary results, 2 RCT post hoc analyses, and 1 analysis combining 2 RCTs data). PDL was associated with a significant increase in the composite outcome of stroke, TIA, or SE (odds ratio 1.63, 95% confidence interval 1.06 to 2.52, p = 0.03, I2 = 43%) as compared with cases with no PDL. There were no significant differences in all-cause or cardiovascular mortality, ischemic stroke, TIA, or device-related thrombus. In conclusion, PDL after LAAC is associated with an increased risk of thromboembolism (composite stroke, TIA, or SE) without impacting mortality.

A Case of Legionnaires' Disease Manifesting as Heat Exhaustion.

A 69-year-old male with a history of prior admissions of heat exhaustion presented with non-specific symptoms including fatigue, diarrhea, and dehydration. The workup revealed a positive legionella urine antigen. He was treated with levofloxacin with symptom resolution within 48 hours.

MULTIPLE RIB FRACTURES, PLEURAL EFFUSION AND RIGHT-SIDED DIAPHRAGMATIC HERNIATION OF THE COLON INTO THE CHEST ASSOCIATED WITH CHRONIC COUGH AFTER COVID-19.

Rib fractures are an infrequent consequence of severe cough. In some patients, undetected rib fractures can lead to life-threatening outcomes. The case of a 73-year-old man who presented with shortness of breath and a worsening dry cough from a SARS-CoV-2 infection for 4 weeks is described. In the emergency department, he was found to be hypoxic and hypotensive. Imaging studies revealed a large right pleural effusion, multiple rib fractures, and right-sided herniation of the colon into the chest. He was admitted to the cardiothoracic intensive care unit where he underwent a flexible bronchoscopy, right video-assisted thoracoscopic surgery, evacuation of a haemothorax, complete decortication, and repair of a diaphragmatic hernia. This case is an unusual presentation of an amalgamation of rare complications resulting from an unrelenting, poorly controlled SARS-CoV-2 infection cough that prompted rapid recognition and swift action. LEARNING POINTS: Physical examination and plain radiography frequently miss costal arch fractures if no bone pathology or history of trauma is present.Controlling cough is important, and decreases the chances of complications and rupture of organs.New-onset chest pain with a background of chronic cough makes cough-induced rib fracture a probable differential diagnosis. Pleural effusion in a patient presenting with cough and a rib fracture should make clinicians suspect haemothorax.

ORGANIZING PNEUMONIA: AN UNUSUAL SEQUELA OF COVID-19 INFECTION.

Organizing pneumonia (OP) is a form of interstitial lung disease that develops in response to acute lung injury. SARS-CoV-2 causes a wide range of lung and extrapulmonary disease, but there are few data suggesting an association between COVID-19 and OP. We describe a patient with COVID-19 pneumonia who developed severe progressive OP with significant morbidity. LEARNING POINTS: COVID-19 pneumonia is one of the secondary causes of organizing pneumonia (OP).Early initiation of steroids in OP is associated with improvement in symptoms and prognosis.A prolonged course of steroids may be needed in COVID-induced OP.
