MDCT usually provides valuable information about this projection and minimizes contrast injection during the TAVR procedure (b). During the procedure, a root angiogram is obtained with the reference pigtail placed in the noncoronary sinus of Valsalva (c). For most patients, the deployment projection is close to 10–15° LAO and 5–10° caudal. N, noncoronary sinus of Valsalva; R, right coronary sinus of Valsalva; L, left coronary sinus of Valsalva. A. Crestanello and B. George Fig. 6 (a) The aortic valve is crossed and pigtails are placed in the ascending aorta (Ao) and left ventricle (LV).
3b, f). However, given the angulation of the ascending aorta and the ventricle, that situation is rare (Fig. 3a, c) and guidewire adjustment is necessary to make the valve more coaxial. The optimal deployment depth is when the annular plane is within 2 mm from node 1 (2–6 mm depth) of the CoreValve using the pigtail in the noncoronary cusp as a landmark for the annular plane (Figs. 5). Valve deployment is performed by 2 operators. Operator number one is located closer to the delivery sheath and controls the shaft of the delivery catheter.
120). 5 % vs. 001). 2 % vs. 3 % vs. 713) mortality . Complications Complications associated with TAVR include vascular complications, valve malpositioning, regurgitation, embolization, coronary compromise, conduction abnormalities, stroke/transient ischemic attack, acute kidney injury, cardiac tamponade, and hemodynamic collapse . A thorough understanding of the procedure and early identiﬁcation and management of complications are necessary for procedural success. Paravalvular Regurgitation (PVR) Multiple studies have demonstrated that PVR after TAVR is associated with poor survival after balloon-expandable TAVR [7, 75, 76].
