Practical update on imaging and transcatheter aortic valve implantation

Figure 1 Transesophageal echocardiography 2D at 129° in long axis view in systole with measurements of the left ventricular outflow tract and aortic annulus. The measurement in blue is the distance to the rigth coronary artery.
