Abstract

Background: Data on interventional treatment of intermediate-high (and high-risk pulmonary embolism (PE) are limited. The authors sought to evaluate the safety and efficacy of catheter-directed mechanical aspiration thrombectomy (CDMT) in a real-world PE patient population.

Methods: This multicenter, prospective registry enrolled PE patients treated with CDMT using the Lightning 12 System. The primary safety endpoints included in-hospital all-cause mortality, procedure-related major bleeding, clinical deterioration, or bailout to another strategy. The primary efficacy outcomes included the reduction of pulmonary arterial pressures and change in the right-to-left ventricular (RV/LV) ratio 48 h after the CDMT. Multivariate regression analyzed characteristics associated with RV/LV improvement.

Results: Our analysis included 150 patients, 72% with intermediate-high PE and 28% with high-risk PE. Systemic thrombolysis was contraindicated in 33.3%, whereas in 4% it failed. There were 2% intraprocedural deaths (1.3% due to RV failure and 0.7% due to massive interstitial bleeding), with no more deaths during follow-up. In 0.7%, CDMT was converted to open surgery, and in 0.7%, bailout systemic thrombolysis and extracorporeal oxygenation support. Major bleedings occurred in 1.3% within 48 h post CDMT. Immediate hemodynamic improvements included a mean 11.3±10 mmHg (22.1%) drop in systolic pulmonary arterial pressure (p < 0.0001) and a median 0.33 (0.25-0.45), (25.2%) drop in RV/LV ratio (p < 0.0001 for paired values), CONCLUSIONS: Aspiration thrombectomy with the Lightning 12 system characterizes an acceptable safety profile, substantial improvements in hemodynamic outcomes, and low mortality for patients with intermediate-high and high-risk PE.
