Hunter and Lillehei [49] |
Valve is brought to anatomic annulus by transverse plication of atrializedRV |
Anterior and posterior leaflets function as bicuspid valve |
Reduced |
No effect |
| 1972 |
Danielson [46]
|
Valve is repaired or replaced at level of functional annulus (high need for TVR[179]) |
Anterior leaflet functions as monocusp |
Reduced
(transverse plication of atrialized RV |
No effect |

Carpentier [47]
|
Valve is brought to the anatomic annulus (anterior/posterior leaflets detached, annular ring) |

Reduced
(longitudinal plication of atrialized RV) |
Increased |
