Table 5. Echocardiographic criteria associated with successful aortic valve repair versus criteria that are deemed questionable or unacceptable and require restarting on cardioplumonary bypass.
| Accept | Questionable | Back on pump | |
|---|---|---|---|
| AR grade | Mild | > Mild | |
| AR jet | Central jet | Central jet due to overcorrection | Eccentric jet > trivial |
| Eccentric trivial jet | |||
| cH | ≥4 mm | <4 mm | |
| eH | ≥8 mm | <8 mm | |
| Transvalvular flow | Mean ≤15 mmHg | Infra- or supra-valvular | Mean >15 mmHg |
| Peak ≤30 mmHg | Peak >30 mmHg | ||
| Morphological aspects | Flexible cusp, end-systolic thrill | SRCM without gradient | Significant SRCM |
| TAV: no asymmetric commissural reimplantation | TAV: asymmetric commissural reimplantation without cusp prolapse | TAV: asymmetric commissural reimplantation with cusp prolapse | |
| Coaptation at the mid-level of the Valsalva sinuses | Billowing aspect | Residual prolapse |
AR, aortic regurgitation; cH, coaptation height; eH, effective height; SRCM, systolic restrictive cusp motion; TAV, tricuspid aortic valve.
