Transcatheter aortic valve implantation is a procedure in the context of non-suitable for open surgery. Measurements of aortic root width, aortic valve surface area, and measurements of the aortic tree, coronary vessels, femoral, and subclavian arteries are of critical importance. In the TAVI procedure, the dimensions of the valve to be placed on the patient are determined by the computed tomography method. Appropriate protocols should be selected for coronary scoring and inclusion of coronary arteries in TAVI imaging and after the shooting, images of coronary arteries such as curved MPR and VRT should be processed, and these images should be prepared to guide the physician who will perform the procedure. The device to be used in imaging must be a tomography device with at least 64 MCDT sections. There are two methods for these shots using ECG triggering. These methods are as follows: Retrospective scan and prospective scan. Bolus tracking method for TAVI imaging is one of the most accurate contrast giving methods that can be used. Automatic dose calibration is used. With the success of the method day by day, the importance of “Computerized Tomography TAVI,” which guides physicians during the method, has increase.
Transcateter aort implantation is a closed surgical procedure performed by determining the appropriate aort cover. Aort root, aort cover measurements, in addition to them, measurements of aort tree, coronary veins, femoral, subclavical arteries are of critical importance. The size of the cover to be placed on the patient in the TAVI process is determined by the computer tomography method. The appropriate protocols for the coronary scanning and inclusion of coronary arteries in the TAVI screening should be selected and the images of the coronary arteries, such as Curved MPR, VRT, after the screening should be processed and these images should be prepared to guide the doctor who will perform the process. The device to be used for imaging must have a tomography device with a cut of at least 64 MCDT. There are two methods for these screens using ECG stimulation. These methods are: Retrospective Scanning and Prospective Scanning. The Bolus Monitoring method for TAVI viewing is one of the most accurate methods of contrasting that can be used. Automatic dosage calibration is used. With the success of the method from day to day, the importance of "Computer Tomography of TAVI" that guides the doctors during the method has increased.
