Baseline and immediate Doppler haemodynamic results
| Parameter | Group 1 (n = 84) | Group 2 (n = 384) | p Value (group 1 v 2) | |
|---|---|---|---|---|

| B, before valvotomy; I, immediately after valvotomy; MG, mean transmitral valve gradient; MVA, mitral valve area; NS, non-significant difference. | ||||
