Abstract:
The presence of both mitral and aortic mechanical prostheses often make access to the left ventricle difficult for hemodynamic evaluation of valve gradients and for performing angiography. We present a case where both the transseptal and direct apical ventricular puncture techniques are utilized for assessing prosthetic valve function. The use of a new over the wire technique for left ventricular access using a flexible 4 French pediatric multipurpose catheter is described.
