Comparison of complications between the IVUS-crossable group and IVU-uncrossable group.
| All (n = 284) | IVUS-crossable group (n = 150) | IVUS-uncrossable group (n = 134) | P value | |
|---|---|---|---|---|
| Slow flow (≤ TIMI-2) just after RA | 51 (18.0) | 16 (10.7) | 35 (26.1) | 0.001 |
| Severe slow flow (≤ TIMI-1) just after RA | 17 (6.0) | 4 (2.7) | 13 (9.7) | 0.022 |
| Periprocedural MI with slow flow | 4 (1.4) | 1 (0.7) | 3 (2.2) | 0.346 |
| Final TIMI flow grade ≤ 2 | 2 (0.7) | 0 | 2 (1.5) | 0.222 |
| Vessel perforation (Type III) due to Burr | 1 (0.4) | 0 (0) | 1 (0.7) | 0.472 |
| Burr entrapment | 1 (0.4) | 1 (0.7) | 0 (0) | 1.000 |
Data are expressed as the number (percentage). A Fischer’s exact test was used to compare the 2 groups.
