Feasibility of quantitative assessment of aortic regurgitation in a percutaneous closure of paravalvular leak: expanding videodensitometry

Figure 1. Pre-procedure (A) and post-procedure (B) aortograms and videodensitometry assessment of regurgitation. The right panels show the colour-coded left ventricular outflow tract (LVOT) with the representation of the regurgitating contrast. Underneath are the time-density curves of the aortic root (red curve) and LVOT (yellow curve). The ratio of these curves represents the result of VD-AR assessment in percentage form. The yellow arrows in panel B show the residual central small regurgitation after closure of the PVL.

Quantitative assessment of regurgitation with videodensitometry is a well validated tool in the setting of transcatheter aortic valve implantation (TAVI). It ...
