Regional or global left ventricular (LV) systolic dysfunction and adverse LV remodelling can cause restricted leaflet motion and failure of leaflet coaptation
resulting in MR.1 Thus, the mechanism is largely ventricular rather than valvular.
In case 1, 1 month of external coaptation
resulted in a delayed union, significant osteolysis, and presumptive osteomyelitis, which led to the decision to treat with a key ring fixator.
Long.term clinical outcome after epineural coaptation
of digital nerves.
Transection of the FN should be repaired surgically by coaptation
of the proximal and distal ends, an intervention known as neurorrhaphy .
The system features contoured, broad paddles to maximize coaptation
of the mitral leaflets and a central spacer that fills the regurgitant orifice area.
Data reported previously showed that an increase in stiffness can increase stress in the CT and Leaflets, reducing the probability of valve coaptation
To shorten the axonal regeneration distance, it is desirable to perform nerve coaptation
near the target muscle, closest as possible without tension.
Other alternative techniques, such as artificial chordae, chordal transfer, decalcification, papillary muscle (PPM) repositioning, and sliding plasty, were also used to achieve one basic goal of restoring a smooth and correct-sized leaflet and creating the best coaptation
area in the inflow of the left ventricle.
The quadriceps muscle is the only direct insertion on the bed, such withdrawal can produce lateralization (arc effect) and increased paltelofemural compression (coaptation
Increasing tissue volume at these locations increases urethral luminal coaptation
and bladder outflow resistance (32).
(8) Left atrium myxoma may cause atrial and annular dilatation with mitral insufficiency from inadequate coaptation
of valve leaflets in systole and mitral stenosis from LV filling obstruction during the diastolic phase.
Factors contributing to this complication are the presence of preexisting MR, abnormal cusps coaptation
, stretching of the valve annulus and excessive commissural splitting8,12.
