Figure Lengend Snippet: EchoNavigator virtual marker and fusion imaging for transcatheter closure of paravalvular leak. A: Significant mitral paravalvular leak (PVL) was seen in transesophageal echocardiography (TEE 0 degrees); B: The PVL location at the X-plane views of TEE was marked to generate marker 1 on the fluoroscopic screen; C: A suitable point for transseptal puncture was made under the guidance of TEE; D: The curvature of the Agilis NxT steerable introducer was adjusted for better orientation; E: The PVL defect was crossed with a 0.035-inch guidewire supported by the telescoping system of a 6 Fr MP guide catheter and JR4 diagnostic catheter; F: Three-dimensional TEE showed the first Amplatzer Vascular Plug II (AVP II 12 mm); G: The second AVP II (10 mm) was deployed without releasing the first AVP II; H: The second AVP II (10 mm) was released first; I: Color Doppler mode of the TEE showed only mild residual PVL; J: Three-dimensional TEE showed that the 1st AVP II (12 mm) had been released; K: Final position of the two AVP II (blue arrow heads).

Figure Lengend Snippet: ( A ) Baseline 3D TEE color Doppler showing two round-shaped mitral PVLs with significant regurgitant jets located at 5 o’clock (3.2 mm) and 7 o’clock (3.6 mm) ( a , b ) in a female patient with a mitral bioprosthetic valve replacement; ( c ): successful implantation of a 3 mm-square twist PLD (red asterisk) at 5 o’clock; ( d ): fusion of real-time 2D TEE (Phillips Epiq7) and cardiac fluoroscopy imaging was obtained using EchoNavigator®-system (Philips Healthcare, Best, The Netherlands) with the fused image maintained demonstrating the location of the postero-laterally located (7 o’clock) mitral PVL (yellow circle) that was marked to aid the pathway of the guidewire (black arrow) crossing the leak, particularly in the case of a radiolucent bioprosthetic valve like in our patient. “ * ” refers to 3 mm-square twist PLD. ( B ) Intraprocedural navigation using fusion of 3D TEE and fluoroscopy with the fused image maintained helped the interventionalist to close successfully the second leak with a 5 mm-square twist PLD (black asterisk), improving the safety and the efficacy of this technically challenging procedure. PLD, Occlutech Paravalvular Leak Device ST, square twist, “ * ” refers to 5 mm-square twist PLD.

Article Snippet: In a subset of patients with Mi PVLs, the transapical hybrid approach was applied using EchoNavigator echocardiographic-fluoroscopic fusion imaging software (second release software, Philips Medical Systems, Best, The Netherlands).
