A Rare Cause of Constrictive Pericarditis: Primary Pericardial Mesothelioma.

This clinical vignette highlights the use of echocardiography, computed tomography, positron emission tomography, magnetic resonance imaging, and invasive hemodynamics to aid in making a rare diagnosis. This case highlights a 62-year-old male who presented with worsening dyspnea and was ultimately found to have constrictive pericarditis secondary to primary pericardial mesothelioma. The use of multimodality imaging can facilitate early diagnosis of this rare condition, helping to initiate treatment options for an otherwise high-mortality disease.

Pulmonary artery diameter correlates with echocardiographic parameters of right ventricular dysfunction in patients with acute pulmonary embolism.

Introduction: Right ventricular dysfunction (RVD) is a key component in the process of risk stratification in patients with acute pulmonary embolism (PE). Echocardiography remains the gold standard for RVD assessment, however, measures of RVD may be seen on CTPA imaging, including increased pulmonary artery diameter (PAD). The aim of our study was to evaluate the association between PAD and echocardiographic parameters of RVD in patients with acute PE.

The Inverse Correlation Between the Duration of Lifetime Occupational Radiation Exposure and the Prevalence of Atrial Arrhythmia.

Objective: Advancements in fluoroscopy-assisted procedures have increased radiation exposure among cardiologists. Radiation has been linked to cardiovascular complications but its effect on cardiac rhythm, specifically, is underexplored.

Methods: Demographic, social, occupational, and medical history information was collected from board-certified cardiologists via an electronic survey.

Association Between Atrial Fibrillation and Occupational Exposure in Firefighters Based on Self-Reported Survey Data.

Background Exposure to inhaled smoke, pollutants, volatile organic compounds, and polycyclic aromatic hydrocarbons in the firefighting environment has been associated with detrimental respiratory and cardiovascular effects, making firefighters a unique population with both personal and occupational risk factors for cardiovascular disease. Some of these exposures are also associated with development of atrial fibrillation. We aimed to study the association of atrial fibrillation and occupational exposure in firefighters.

Use of Ambulatory Patch Monitoring Devices to Supplement Inpatient Telemetry-A Descriptive Study of a Single-center Experience During the Coronavirus Disease 2019 Pandemic.

To accommodate the surge in patients with coronavirus disease 2019 during the spring of 2020, outpatient areas in our health system were repurposed as inpatient units. These spaces often lacked the same resources as the standard inpatient unit, including telemetry equipment. We utilized mobile cardiac outpatient telemetry (MCOT) in place of traditional telemetry and suggest that MCOT is an appropriate substitution only for patients at low risk of developing arrhythmia given the prolonged time to notification of the care team regarding events and imprecise measurements of the corrected QT interval when compared to 12-lead electrocardiography.

Malignancy-Related Pulmonary Hypertension Presenting as a Pulmonary Veno-Occlusive-Like Syndrome: A Single-Center Case Series.

Tumoral obstruction is a small, but broadly defined, category of pulmonary hypertension that encompasses microvascular tumor emboli, tumor thrombotic microangiopathy, and macrovascular tumor obstruction within the pulmonary circulation. We present 4 patients with solid tumors, severe pre-capillary pulmonary hypertension, right ventricular failure, and pulmonary veno-occlusive-like disease. ().

Vascular Access for Large Bore Access.

Recent advances in the field of interventional cardiology have allowed for more complex procedures to be performed percutaneously. Ability to obtain safe large bore vascular access is frequently the key factor to procedural success. Meticulous technique for successful vascular access incorporates the understanding of anatomic landmarks, ultrasound, fluoroscopy, and micropuncture.

Outcomes of cardiac resynchronisation therapy in patients with heart failure with atrial fibrillation: a systematic review and meta-analysis of observational studies.

Background: Cardiac resynchronisation therapy (CRT) is beneficial in selected patients with heart failure (HF) in normal sinus rhythm (NSR). We sought to evaluate the impact of CRT with or without atrioventricular junction (AVJ) ablation in patients with HF with concomitant atrial fibrillation (AF).

Methods And Results: Literature was searched (inception through 30 August 2017) for observational studies that reported outcomes in patients with HF with CRT and AF that reported all-cause and cardiovascular mortality.
