Table 2. Comparisons of procedural parameters between 2 groups.
| Procedural parameters | Group 1 (n=216) | Group 2 (n=53) | p value | |
|---|---|---|---|---|
| PT* | 60.5±12.4 | 63.2±12.4 | 0.587 | |
| FT | 6.0±0.9 | 5.9±0.7 | 0.655 | |
| Needs of MIT | 51 (23.6) | 20 (37.7) | 0.034 | |
| Combined procedures | - | |||
| PPV | 3 (1.4) | 0 (0.0) | ||
| Others‡ | 8 (3.8)‡ | 0 (0.0) | ||
Values are presented as mean±standard deviation or number (%).
FT = fluoroscopy time; MIT = modified implantation technique; PPV = percutaenous pulmonary valvuloplasty; PT = procedure time;
*PT was defined as time interval from puncture to completion of hemostasis; ‡4 cases of radiofrequency ablations for atrial fibrillation (n=2) and wolff-parkinson-white syndrome (n=2), 3 cases of direct current cardioversions, 1 case of coronary angioplasty.
