Cardiac magnetic resonance (CMR) characteristics according to mitral valve prolapse status
| Mitral valve prolapse (n=41) | Controls (n=31) | p Value | |
|---|---|---|---|
| LVEDVI, mL/m2 | 103 (25) | 84 (17) | 0.001 |
| LVESVI, mL/m2 | 38 (13) | 33 (8) | 0.10 |
| LVMI, g/m2 | 59 (16) | 53 (13) | 0.10 |
| LVEF,% | 63 (7) | 60 (6) | 0.10 |
| Effective LVEF, % | 45 (9) | 55 (6) | <0.0001 |
| MRF,% | 28 (14) | 8 (6) | <0.0001 |
| LGE, n (%) | 11 (28) | 0 (0) | <0.0001 |
| Myocardial T1 time, ms | 334 (52) | 363 (58) | 0.03 |
| Gadopentetate dimeglumine, mmol/kg | 0.2 (0.03) | 0.2 (0.03) | 0.97 |
| T1 postcontrast acquisition time, min | 21 (4) | 21 (3) | 0.80 |
The categorical variable LGE is presented as number of patients with LGE (%). Remaining variables (all continuous) are presented as mean (SD).
LGE, late gadolinium enhancement; LVEDVI, left ventricular end-diastolic volume index; LVEF, left ventricular ejection fraction; LVESVI, left ventricular end-systolic volume index; LVMI, left ventricular mass index; MRF, mitral regurgitation fraction.
P-value <0.05 are shown in bold.
