Observed 1-, 5-, and 10-year survival in patients with mitral annular calcification-related mitral valve dysfunction according to mean transmitral gradient
| Survival | n | Median survival (95% CI) | 1 year (%) | 5 years (%) | 10 years (%) |
|---|---|---|---|---|---|
| Control group (MAC, gradient <3 mmHg) | 866 | 5.5 (4.5–6.4) | 82 | 52 | 25 |
| 3 ≤ transmitral gradient ≤5 mmHg | 3926 | 3.8 (3.6–4.1) | 77 | 42 | 18 |
| 5 < transmitral gradient <10 mmHg | 1476 | 3.1 (2.7–3.4) | 73 | 38 | 17 |
| Transmitral gradient ≥10 mmHg | 351 | 2.1 (1.6–2.5) | 67 | 25 | 11 |
