Neo-Commissural Alignment by Withdrawing and Readvancing the Delivery System during Transcatheter Aortic Valve Replacement with Self-Expanding Prosthesis

Figure 3

Neo-commissure alignment by manipulating the delivery system. Column 1: angiograms when the THV crossed the aortic annulus at the first time. The centre markers were close to or overlapped with the left markers. Column 2: angiograms after the delivery system were withdrawn to the descending aorta and readvanced to the aortic annulus. The centre markers were close to or overlapped with the right markers. Column 3: angiograms after the THV were deployed. Column 4: transverse aortic sinus CT images before TAVR. Column 5: transverse aortic sinus CT images after TAVR. THV = transcatheter heart valve; CT = computed tomography; TAVR = transcatheter aortic valve replacement; RAO = right anterior oblique; LAO = left anterior oblique; CAU = caudal; and LCA = left coronary artery.
