Figure 1 Collision mechanism of hemolysis. Follow-up inverted longitudinal multiplane TEE imaging. (A) Central mitral leaflet coaptation is mildly attenuated (large arrow) after mitral repair with Cosgrove-Edwards ring annuloplasty. A cross-section of the ring (arrowhead) with suture material (small arrow) is seen. (B) Color Doppler imaging reveals a jet of mitral regurgitation (large arrow) which immediately collides with the annuloplasty ring (arrowhead), redirecting the jet at an acute angle into the central LA (small arrows).
