Primary and secondary outcome measures of the study groups.
| CDT (n=15) | P | |||
|---|---|---|---|---|
| Total (N=15) | Massive PE (N=6) | Submassive PE (N=9) | ||
| In-hospital mortality | 2 (13.3) | 1 (6.7) | 1 (6.7) | 1.00 |
| 30-day mortality | 3 (20) | 2 (13.3) | 1 (6.7) | 0.52 |
| Hemodynamic stabilization achieved | 14 (93.3) | 5 (33.3) | 9 (60) | 0.40 |
| Δ Pulmonary artery pressure, median [IQR] | 25 [9–30] | 26 [10–37] | 20 [9–30] | 0.64 |
| Major bleeding | 1 (6.7) | 0 | 1 (6.7) | 1.00 |
| Minor bleeding | 4 (26.7) | 1 (6.7) | 3 (20) | 0.60 |
Data presented as number of cases (% of the total study population) unless otherwise stated. Statistical significance was determined by the Pearson’s chi-square goodness-of-fit test for group comparisons, the Mann-Whitney U test for comparison of continuous non-normal data between massive PE vs. submassive PE groups. CDT – catheter-directed therapy; PE – pulmonary emboli; IQR – interquartile range 25 to 75.
