High-Risk Pulmonary Embolism: Management for the Intensivist

High-risk pulmonary embolism (PE) also known as massive PE carries a high rate of morbidity and mortality. The incidence of high-risk PE continues to increase, yet the outcomes of high-risk PE continue to remain poor. Patients with high-risk PE are often critically ill, with complex underlying physiology, and treatment for the high-risk PE patient almost always requires care and management from an intensivist. Treatment options for high-risk PE continue to evolve rapidly with multiple options for definitive reperfusion therapy and supportive care. A thorough understanding of the physiology, risk stratification, treatment, and support options for the high-risk PE patient is necessary for all intensivists in order to improve outcomes. This article aims to provide a review from an intensivist's perspective highlighting the physiological consequences, risk stratification, and treatment options for these patients as well as providing a proposed algorithm to the risk stratification and acute management of high-risk PE.

Pulmonary Embolism Center of Excellence: Putting It All Together

Center of excellence (COE) designations are generally used to identify programs with expertise in a specific area of medicine. Meeting criteria for a COE may result in advantages including improved clinical outcomes, marketing advantages, and improved financial performance. However, criteria for COE designations are highly variable, and they are granted by a wide variety of entities. The diagnosis and treatment of both acute pulmonary emboli and chronic thromboembolic pulmonary hypertension are disciplines that require multidisciplinary expertise, highly coordinated care, specialized technology and advanced skillsets gained through high patient volumes.

Pulmonary embolism response teams: Changing the paradigm in the care for acute pulmonary embolism

Pulmonary embolism response teams (PERTs) have emerged as a multidisciplinary, multispecialty team of experts in the care of highly complex symptomatic acute pulmonary embolism (PE), with a centralized unique activation process, providing rapid multimodality assessment and risk stratification, formulating the best individualized diagnostic and therapeutic approach, streamlining the care in challenging clinical case scenarios (e.g., intermediate-high risk and high-risk PE), and facilitating the implementation of the recommended therapeutic strategies on time. PERTs are currently changing how complex acute PE cases are approached. The structure, organization, and function of a given PERT may vary from hospital to hospital, depending on local expertise, specific resources, and infrastructure for a given academic hospital center. Current emerging data demonstrate the value of PERTs in improving time to PE diagnosis; shorter time to initiation of anticoagulation reducing hospital length of stay; increasing use of advanced therapies without an increase in bleeding; and in some reports, decreasing mortality. Importantly, PERTs are positively impacting outcomes by changing the paradigm of care for acute PE through global adoption by the health-care community.

Right heart thrombi (RHT) and clot in transit with concomitant PE management: Approach and considerations

Right heart thrombi (RHT) continues to pose a clinical dilemma for multiple specialties and is especially concerning when present with concomitant pulmonary embolism (PE). Patients with PE and RHT are at an increased risk of poor outcomes compared to PE without RHT. Although the exact incidence of RHT is unknown, the increasing use of point-of-care ultrasound may lead to an increased detection and frequency of RHT. There are multiple treatment strategies available for RHT, including anticoagulation, systemic thrombolysis, and endovascular and surgical therapies. Given that these treatment strategies involve multiple medical specialties, the management of RHT with concomitant PE can be complex. Currently, there is limited clinical data and guidelines on the treatment and management of RHT. We aim to provide a review on RHT with concomitant PE, including risk stratification, treatment considerations, and our approach to the management of RHT.
