Pulmonary embolism reperfusion

BACKGROUND: Pulmonary Embolism Severity Index (PESI) and simplified PESI (sPESI) methods are used in the evaluation of patients with suspected acute pulmonary thromboembolism (PTE). OBJECTIVES: This study aimed to provide a rapid mortality risk stratification in patients with acute pulmonary thromboembolism (PTE) immediately after admission without relying on laboratory data by using quick sequential organ failure assessment (qSOFA), a three-parameter scoring system with proven efficiency used for swift prediction of organ dysfunction, and compare it with Pulmonary Embolism Severity Index (PESI) and simplified PESI (sPESI)...

BACKGROUND: Multidisciplinary Pulmonary Embolism Response Teams (PERTs) were established to individualize the treatment of high-risk (HR) and intermediate-high-risk (IHR) pulmonary embolism (PE) patients, which pose a challenge in clinical practice. METHODS: We retrospectively collected the data of all HR and IHR acute PE patients consulted by PERT CELZAT between September 2017 and October 2022. The patient population was divided into four different treatment methods: anticoagulation alone (AC), systemic thrombolysis (ST), surgical embolectomy (SE), and catheter-directed therapies (CDTx)...

Introduction The coronavirus disease 2019 (COVID-19) pandemic has brought about significant changes in the medical field. While primarily characterized as a respiratory syndrome, COVID-19 is also associated with vascular events, particularly thrombotic complications. These events can manifest as initial presentations or develop as complications during the course of the disease, predominantly driven by immune-mediated mechanisms. Methods Patients with thrombotic complications followed in the post-COVID-19 thrombosis consult of 2021 were retrospectively analyzed and assessed for predisposing factors for pulmonary embolism (PE), including thrombophilias...

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...

PURPOSE OF REVIEW: Pulmonary embolism is the third most frequent type of cardiovascular disease behind coronary artery disease and stroke. Patients with acute pulmonary embolism have significant variability in short-term mortality from less than 0.6% in low-risk patients to 19% in high-risk patients. Risk stratification plays an important role in the management of acute pulmonary embolism as it can determine the need for urgent reperfusion therapies versus conservative strategies. RECENT FINDINGS: The three fundamental steps of risk stratification include the immediate identification of patients that are at high risk for mortality, the identification of patients that are at an increased risk of complications from pulmonary embolism that requires hospital monitoring and potential escalation of therapies, and the identification of patients at a low risk that can be treated as an outpatient...

High-risk pulmonary embolism (PE) is associated with significant morbidity and mortality. Systemic thrombolysis (ST) remains the most evidenced-based treatment for hemodynamically unstable PE but, in daily clinical practice, it remains largely underused. In addition, unlike acute myocardial infarction or stroke, a clear time window for reperfusion therapy, including fibrinolysis, for high-risk PE has not been defined either for fibrinolysis, or for the more recently incorporated options of catheter-based thrombolysis or thrombectomy...

BACKGROUND: HIV-infected individuals are known to be at higher risk for thrombotic cardiovascular disease (CVD), which may also be differentially affected by components of anti-HIV drugs. To identify the effects of a series of FDA-approved anti-HIV drugs on platelet aggregation in humans, focusing on the novel pharmacological effects of rilpivirine (RPV), a reverse transcriptase inhibitor, on platelet function both in vitro and in vivo and the mechanisms involved. METHODS AND RESULTS: In vitro studies showed that RPV was the only anti-HIV reagent that consistently and efficiently inhibited aggregation elicited by different agonists, exocytosis, morphological extension on fibrinogen, and clot retraction...

BACKGROUND: Exact benefits of currently recommended close monitoring in intermediate high risk acute pulmonary embolism (PE) patients are unknown. METHODS: This prospective observational cohort study determined clinical characteristics, and disease course of intermediate high risk acute PE patients in an academic hospital setting . Frequency of hemodynamic deterioration, use of rescue reperfusion therapy and PE related mortality, were outcomes of interest. RESULTS: Of 98 intermediate high risk PE patients included for analysis, 81 patients (83%) were closely monitored...

Pulmonary embolism is a frequent cardiovascular disease which in recent years has shown a reduction in the mortality but an increase in the incidence. Due to the optimization of clinical probability scores and the interpretation of the D‑dimer test, unnecessary examinations using computed tomography with respect to the exclusion of an acute pulmonary embolism can be avoided, also in pregnant women. The evaluation of the right ventricle contributes to a risk-adapted treatment. Treatment consists of anticoagulation, alone or in combination with reperfusion treatment, such as systemic thrombolysis and also catheter-assisted or surgical treatment...

BACKGROUND: acute pulmonary embolism (APE) is a complex and potentially deadly entity, with a variable clinical course, considered the third cardiovascular cause of death. Its management varies according to the stratified risk from anticoagulation to reperfusion therapy, suggesting systemic thrombolysis as a first-choice strategy; however, in a large group of patients their use will be contraindicated, discouraged or will have failed, thus recommending as options in such cases endovascular therapies or surgical embolectomy...

Approximately 5% of pulmonary embolism (PE) cases present with persistent hypotension, obstructive shock, or cardiac arrest. Given the high short-term mortality, management of high-risk PE cases focuses on immediate reperfusion therapies. Risk stratification of normotensive PE is important to identify patients with an elevated risk of hemodynamic collapse or an elevated risk of major bleeding. Risk stratification for short-term hemodynamic collapse includes assessment of physiological parameters, right heart dysfunction, and identification of comorbidities...

BACKGROUND: The clinical manifestations of pulmonary embolism are varied, and atypical pulmonary embolism can easily be missed in some patients, resulting in serious clinical consequences and injuries. CASE DESCRIPTION: This report describes a rare case of acute pulmonary embolism with loss of consciousness as the first manifestation. A 50-year-old male was admitted with loss of consciousness and difficulty breathing. Acute coronary syndromes and neurological disorders such as seizures were excluded by clinical history and electrocardiogram dynamic changes...

Intracardiac thrombosis and/or pulmonary thromboembolism (ICT/PE) is a rare but devastating complication during liver transplantation. Its pathophysiology remains poorly understood, and successful treatment remains a challenge. This systematic review summarizes the available published clinical data regarding ICT/PE during liver transplantation. Databases were searched for all publications reporting on ICT/PE during liver transplantation. Data collected included its incidence, patient characteristics, the timing of diagnosis, treatment strategies, and patient outcomes...

BACKGROUND: Pulmonary embolism severity index, its simplified version, and shock index have been used for risk stratification in acute pulmonary embolism. In this study, we proposed a modification in severity index and evaluated the correlates and prognostic value of modification in severity index in this setting. METHODS: The study group comprised retrospectively evaluated 181 patients with acute pulmonary embolism. Systematic workup including pulmonary embolism severity index, its simplified version, shock index, biomarkers, and echocardiographic and multidetector computed tomography assessments was performed in all patients...

Pulmonary embolism (PE) is the third-leading cause of cardiovascular mortality and the second-leading cause of death in cancer patients. The clinical efficacy of thrombolysis for acute PE has been proven, yet the therapeutic window seems narrow, and the optimal dosing for pharmaceutical reperfusion therapy has not been established. Higher doses of systemic thrombolysis inevitably associated with an incremental increase in major bleeding risk. To date, there is no high-quality evidence regarding dosing and infusion rates of thrombolytic agents to treat acute PE...

OBJECTIVE: To determine the prevalence of hemoptysis secondary to post-embolization systemic collaterals and review the recurrence rate and treatment outcomes. METHODS: The records of 930 patients with PAVM (801 with known or possible HHT), from a single HHT center between July 2, 1996 and July 22, 2021, were searched for a single lifetime episode of hemoptysis secondary to post-embolization systemic collaterals. Embolization was performed with permanent particles or gelatin slurry...

OBJECTIVE: Chronic thromboembolic pulmonary hypertension is potentially curable via pulmonary thromboendarterectomy. A minority of patients experience recurrence of their symptoms and are eligible for repeat pulmonary thromboendarterectomy. However, little data exist regarding risk factors and outcomes for this patient population. METHODS: We performed a retrospective review of the University of California San Diego chronic thromboembolic pulmonary hypertension quality improvement database, including all patients who underwent pulmonary thromboendarterectomy from December 2005 to December 2020...

Clinical outcomes for intermediate or high-risk pulmonary emboli (PE) remain sub-optimal, with limited improvements in survival for the past 15 years. Anticoagulation alone results in slow thrombus resolution, persistent right ventricular (RV) dysfunction, patients remaining at risk of haemodynamic decompensation and increased likelihood of incomplete recovery. Thrombolysis elevates risk of major bleeding and is thus reserved for high-risk PE. Thus, a huge clinical need exists for an effective technique to restore pulmonary perfusion with minimal risk and avoidance of lytic therapy...

INTRODUCTION: Acute pulmonary embolism (PE) is a disease with a broad spectrum of clinical presentations. While some patients can be treated at home or may even be left untreated, other patients require an aggressive approach with reperfusion treatment. AREAS COVERED: (1) Advanced reperfusion treatment in hemodynamically stable acute PE patients considered to be at high risk of decompensation and death, (2) the treatment of subsegmental pulmonary embolism, (3) outpatient treatment for hemodynamically stable PE patients with signs of right ventricle (RV) dysfunction, and (4) the optimal approach to identify and treatpost-PE syndrome...
