Data are presented as median (range) or number (percentage).
PMT, percutaneous mechanical thrombectomy; bpm, beats per minute; RV, right ventricular; LV, left ventricular; FiO2, inspired oxygen fraction.
Invasive pulmonary arterial pressure was measured with a pulmonary arterial catheter. Bold indicates p value < 0.05.
