Impact of Pulmonary Embolism Response Team on Anticoagulation Prescribing Patterns in Patients With Acute Pulmonary Embolism.

INTRODUCTION: Anticoagulation remains the mainstay pharmacotherapy for acute pulmonary embolism (PE), but multiple treatment options exist. The Pulmonary Embolism Response Team (PERT) is a multidisciplinary group that evaluates patients, formulates evidence-based treatment plans, and mobilizes resources. The objective of this study was to characterize the anticoagulation prescribing patterns made by PERT and to determine the clinical impact of anticoagulant selection. MATERIALS AND METHODS: This was a retrospective analysis of patients evaluated by PERT from 2016 to 2018. Multivariable linear regression was conducted to determine predictors of length of stay (LOS). RESULTS: A total of 209 patients were evaluated by PERT and received anticoagulation on discharge. Of those, 47% received a non-vitamin K oral anticoagulant (NOAC), 29% received warfarin, and 23% received low-molecular-weight heparin. Patient preferences and comorbidities were the most common reasons for NOAC omission. Patients who received NOACs had a shorter median LOS than warfarin (6.1 [4.6-7.6] days vs 10.9 [8.4-13.4] days; P < .05). Selection of NOAC upon discharge was the only factor independently associated with reduced LOS (ß coefficient: -0.6; 95% CI: -1.01 to -0.18; P < .01). CONCLUSION: The most common recommendation made by PERT was to initiate a NOAC upon discharge, resulting in shorter hospital LOS compared to patients who received warfarin.

The 2020 ACC/AHA Guidelines for Management of Patients With Valvular Heart Disease: Highlights and Perioperative Implications.

Valvular heart disease contributes to a large burden of morbidity and mortality in the United States. During the last decade there has been a paradigm shift in the management of valve disease, primarily driven by the emergence of novel transcatheter technologies. In this article, the latest update of the American College of Cardiology/American Heart Association valve heart disease guidelines is reviewed.

Pulmonary Embolism Complicated by Acute Limb Ischemia Managed by Surgical Pulmonary Embolectomy.

Acute pulmonary embolism (PE) is a manifestation of venous thromboembolic disease with potential serious and life-threatening complications. Management options for acute PE have drastically improved over the last 15 years with the introduction of multidisciplinary pulmonary embolism response teams throughout the world. We present the case of an 18-year-old woman diagnosed with acute PE complicated by near-complete occlusion of her left common femoral artery from a paradoxical embolus in the setting of patent foramen ovale (PFO), managed with surgical pulmonary embolectomy and surgical PFO repair.

Right Ventricular Outflow Doppler Predicts Low Cardiac Index in Intermediate Risk Pulmonary Embolism.

Intermediate-risk pulmonary embolism (PE) has variable outcomes. Current risk stratification models lack the positive predictive value to identify patients at highest risk of PE-related mortality. We identified intermediate-risk PE patients who underwent catheter-based interventions and right heart catheterization (RHC) and identified those with low cardiac index (CI < 2.2 L/min/m2). We utilized regression models to identify echocardiographic predictors of low CI and Kaplan Meier curve to evaluate PE-related mortality when stratified by the echocardiographic predictor. Of 174 intermediate-risk PE patients, 41 underwent RHC. Within this cohort, 46.3% had low CI. Univariable linear regression identified right ventricular outflow tract velocity time integral (RVOT VTI), right/left ventricular ratio, S prime, inferior vena cava diameter, and pulmonary artery systolic pressure as potential predictors of low CI. Multivariable linear regression identified RVOT VTI as significant predictor of low CI (ß coefficient 0.124, 95% confidence interval [CI]: 0.01-0.24, P = .034). Right ventricular outflow tract velocity time integral <9.5 cm was associated with increased PE-related mortality, P = .002. A substantial proportion of intermediate-risk PE patients referred for catheter-based interventions had low CI despite normotension. Right ventricular outflow tract velocity time integral was a significant predictor of low CI. Low RVOT VTI was associated with increased PE-related mortality.
