Ultrasound-assisted catheter-directed thrombolysis in a patient with COVID-19 infection and bilateral intermediate-to-high-risk pulmonary embolism: a case report.

ABSTRACT:

Background

Acute pulmonary embolism (PE) is a common cardiovascular disorder, potentially associated with high morbidity and mortality rates.

Case summary

Herein, we report on a patient with COVID-19 infection and bilateral PE, who presented after cardiovascular resuscitation with return of spontaneous circulation. Initially, an acute coronary syndrome was suspected but bedside echocardiography showed dilatation of the right ventricle (RV) and RV dysfunction, helping to establish the diagnosis of acute intermediate-to-high-risk PE, which was subsequently confirmed by contrast-enhanced computed tomography pulmonary angiography. The patient was successfully treated using low-dose (12 mg of tissue plasminogen) ultrasound-assisted catheter-directed thrombolysis, which resulted in prompt clinical improvement and reversal of RV dysfunction without bleeding complications.

Discussion

This case demonstrates the importance of echocardiography for the differential diagnosis of PE and of catheter-directed thrombolysis for its treatment in patients with intermediate-to-high-risk and high-risk PEs.

Project description:BackgroundPrior clinical trials have demonstrated the efficacy of ultrasound-facilitated catheter-directed thrombolysis (USCDT) for the treatment of acute intermediate-risk pulmonary embolism (PE) using reduced thrombolytic doses and shorter infusion durations. However, utilization and safety of such strategies in broader PE populations remain unclear. The KNOCOUT PE (The EKoSoNic Registry of the Treatment and Clinical Outcomes of Patients With Pulmonary Embolism) registry is a multicenter international registry designed to study the treatment of acute PE with USCDT, with focus on safety outcomes.MethodsThe KNOCOUT PE prospective cohort included 489 patients (64 sites internationally) with acute intermediate-high or high-risk PE treated with USCDT between March 2018 and June 2020. Principal safety outcomes were independently adjudicated International Society on Thrombosis and Haemostasis major bleeding at 72 hours post-treatment and mortality within 12 months of treatment. Additional outcomes included change in right ventricular/left ventricular ratio and quality of life measures over 12 months.ResultsMean alteplase (r-tPA [recombinant tissue-type plasminogen activator]) infusion duration was 10.5 hours. Mean total r-tPA dose was 18.1 mg, with 31.0% of patients receiving ≤12 mg. Major bleeding events within 72 hours occurred in 1.6% (8/489) of patients. One patient experienced worsening of a preexisting subdural hematoma after USCDT and therapeutic anticoagulation, which ultimately required surgery. All-cause mortality at 30 days was 1.0% (5/489). Improvement in PE quality of life score was observed with a 41.1% (243/489, 49.7%) and 44.2% (153/489, 31.3%) mean relative reduction by 3 and 12 months, respectively.ConclusionsIn a prospective observational cohort study of patients with intermediate-high and high-risk PE undergoing USCDT, mean r-tPA dose was 18 mg, and the rates of major bleeding and mortality were low.RegistrationURL: https://www.clinicaltrials.gov; Unique identifier: NCT03426124.

Project description:ObjectiveThrombolytic therapy has been a mainstay of treatment for massive or submassive pulmonary embolism (PE), a common and highly morbid pathology. New percutaneous mechanical thrombectomy (PMT) devices have recently become widely available and have been used increasingly for the treatment of acute PE, but evidence demonstrating its efficacy over standard catheter-directed lytic protocol remains limited.MethodsUsing TriNetX Data Network, a global federated database of >250 million patients, we conducted a retrospective cohort study of patients from January 2017 to August 2023 with a diagnosis of PE, treated with either PMT or catheter-directed thrombolysis (CDT). Eligible patients were 1:1 propensity score-matched for preoperative covariates including demographics and comorbidities. We calculated and compared the 30-day outcomes of all-cause mortality, bleeding complications (blood transfusion, gastrointestinal bleed, and intracranial hemorrhage), diagnosis of acute respiratory failure (RF), myocardial infarction (MI), and pulmonary hypertension (PH) using odds ratios (OR) with 95% confidence intervals (CIs). Also, the 5-year outcomes of all-cause mortality, a composite outcome of chronic PH (chronic PE, chronic cor pulmonale, chronic thromboembolic PH), right heart failure (RHF), RF, and emergency department visits, were compared using hazard ratios (HRs) with 95% CIs.ResultsWe identified 2978 patients treated with PMT and 1137 patients treated with CDT. After matching, we compared 1102 patients in each cohort. For 30-day outcomes, all-cause mortality, acute RF, and blood transfusion were similar between the two groups. However, compared with CDT, PMT was associated with a better safety profile, including lower bleeding risk for both ICH (OR, 0.46; 95% CI, 0.24-0.890) and gastrointestinal bleed (OR, 0.42; 95% CI, 0.28-0.63). PMT also demonstrated better immediate functional outcomes, with less PH (OR, 0.53; 95% CI, 0.41-0.68) and MI (OR, 0.54; 95% CI, 0.41-0.76). At 5 years, the all-cause mortality and RF for both procedures were similar, but PMT was associated with lower rates of chronic PH (HR, 0.70; 95% CI, 0.55-0.90), RHF (HR 0.49; 95% CI, 0.37-0.65), and emergency department visits (348 for PMT vs 426 for CDT; P < .01).ConclusionsIn patients undergoing catheter-based therapy for PE, PMT has an improved procedural safety profile vs CDT and results in significantly fewer 30-day postoperative complications, with fewer bleeding events, and is also associated with fewer periprocedural MIs and less acute PH. Perhaps, more important, PMT also demonstrated improved long-term outcomes with significantly fewer chronic PH and RHF diagnoses with fewer emergency department visits.

Project description:ImportanceThe optimal treatment of intermediate-high-risk pulmonary embolism (PE) remains unknown.ObjectiveTo assess the effect of conventional catheter-directed thrombolysis (cCDT) plus anticoagulation vs anticoagulation monotherapy in improving echocardiographic measures of right ventricle (RV) to left ventricle (LV) ratio in acute intermediate-high-risk PE.Design, setting, and participantsThe Catheter-Directed Thrombolysis vs Anticoagulation in Patients with Acute Intermediate-High-Risk Pulmonary Embolism (CANARY) trial was an open-label, randomized clinical trial of patients with intermediate-high-risk PE, conducted in 2 large cardiovascular centers in Tehran, Iran, between December 22, 2018, through February 2, 2020.InterventionsPatients were randomly assigned to cCDT (alteplase, 0.5 mg/catheter/h for 24 hours) plus heparin vs anticoagulation monotherapy.Main outcomes and measuresThe proportion of patients with a 3-month echocardiographic RV/LV ratio greater than 0.9, assessed by a core laboratory, was the primary outcome. The proportion of patients with an RV/LV ratio greater than 0.9 at 72 hours after randomization and the 3-month all-cause mortality were among secondary outcomes. Major bleeding (Bleeding Academic Research Consortium type 3 or 5) was the main safety outcome. A clinical events committee, masked to the treatment assignment, adjudicated clinical outcomes.ResultsThe study was prematurely stopped due to the COVID-19 pandemic after recruiting 94 patients (mean [SD] age, 58.4 [2.5] years; 27 women [29%]), of whom 85 patients completed the 3-month echocardiographic follow-up. Overall, 2 of 46 patients (4.3%) in the cCDT group and 5 of 39 patients (12.8%) in the anticoagulation monotherapy group met the primary outcome (odds ratio [OR], 0.31; 95% CI, 0.06-1.69; P = .24). The median (IQR) 3-month RV/LV ratio was significantly lower with cCDT (0.7 [0.6-0.7]) than with anticoagulation (0.8 [0.7-0.9); P = .01). An RV/LV ratio greater than 0.9 at 72 hours after randomization was observed in fewer patients treated with cCDT (13 of 48 [27.0%]) than anticoagulation (24 of 46 [52.1%]; OR, 0.34; 95% CI, 0.14-0.80; P = .01). Fewer patients assigned to cCDT experienced a 3-month composite of death or RV/LV greater than 0.9 (2 of 48 [4.3%] vs 8 of 46 [17.3%]; OR, 0.20; 95% CI, 0.04-1.03; P = .048). One case of nonfatal major gastrointestinal bleeding occurred in the cCDT group.Conclusions and relevanceThis prematurely terminated randomized clinical trial of patients with intermediate-high-risk PE was hypothesis-generating for improvement in some efficacy outcomes and acceptable rate of major bleeding for cCDT compared with anticoagulation monotherapy and provided support for a definitive clinical outcomes trial.Trial registrationClinicalTrials.gov Identifier: NCT05172115.

Project description:BackgroundTherapeutic options for intermediate- or high-risk pulmonary embolism (PE) include anticoagulation, systemic thrombolysis and catheter-directed thrombolysis (CDT); however, the role of CDT remains controversial. We sought to compare the efficacy and safety of CDT with other therapeutic options using network meta-analysis.MethodsWe searched PubMed (MEDLINE), Embase, ClinicalTrials.gov and Cochrane Library from inception to Oct. 18, 2022. We included randomized controlled trials and observational studies that compared therapeutic options for PE, including anticoagulation, systemic thrombolysis and CDT among patients with intermediate- or high-risk PE. The efficacy outcome was in-hospital death. Safety outcomes included major bleeding, intracerebral hemorrhage and minor bleeding.ResultsWe included data from 44 studies, representing 20 006 patients. Compared with systemic thrombolysis, CDT was associated with a decreased risk of death (odd ratio [OR] 0.43, 95% confidence interval [CI] 0.32-0.57), intracerebral hemorrhage (OR 0.44, 95% CI 0.29-0.64), major bleeding (OR 0.61, 95% CI 0.53-0.70) and blood transfusion (OR 0.46, 95% CI 0.28-0.77). However, no difference in minor bleeding was observed between the 2 therapeutic options (OR 1.11, 95% CI 0.66-1.87). Compared with anticoagulation, CDT was also associated with decreased risk of death (OR 0.36, 95% CI 0.25-0.52), with no increased risk of intracerebral hemorrhage (OR 1.33, 95% CI 0.63-2.79) or major bleeding (OR 1.24, 95% CI 0.88-1.75).InterpretationWith moderate certainty of evidence, the risk of death and major bleeding complications was lower with CDT than with systemic thrombolysis. Compared with anticoagulation, CDT was associated with a probable lower risk of death and a similar risk of intracerebral hemorrhage, with moderate certainty of evidence. Although these findings are largely based on observational data, CDT may be considered as a first-line therapy in patients with intermediate- or high-risk PE.Protocol registrationPROSPERO - CRD42020182163.
