Transcatheter aortic valve replacement postoperative complication prediction method, device and equipment

Abstract

The invention relates to a transcatheter aortic valve replacement (TAVI) postoperative complication prediction method, device and equipment, and belongs to the technical field of postoperative prediction, the method comprises the following steps: acquiring feature data of a target patient, and correspondingly inputting the feature data into a preset TAVI postoperative complication prediction model to obtain a TAVI postoperative complication prediction result of the target patient; the TAVI postoperative complication prediction result comprises a TAVI postoperative pacemaker implantation prediction result and a TAVI postoperative perivalvular leakage prediction result. According to the method, the feature data is obtained from the anatomical indexes under the CT data and is easy to obtain, and compared with a scheme using finite elements, the method is easier to popularize and software; according to the method, the problem of the initial implantation depth of the artificial aortic valve in the release process is concerned, compared with a finite element scheme, only the implantation depth of the artificial valve after the valve is completely released is concerned, the clinical application value is higher, and meanwhile prediction of the clinical outcome is more accurate.

Description

technical field [0001] The invention belongs to the technical field of postoperative prediction, and in particular relates to a method, device and equipment for predicting postoperative complications of transcatheter aortic valve replacement. Background technique [0002] Aortic valve disease, including aortic stenosis and regurgitation, is a common heart valve disease, and patients with symptomatic aortic valve disease often have a poor prognosis. Transcatheter Aortic Valve Implantation (TAVI) is a new type of minimally invasive treatment technique for aortic valve disease, which involves passing a compressed artificial aortic valve (a stent with the valve sewn) through the The vascular route is released to the diseased aortic valve to realize the treatment of the disease, which has the characteristics of small trauma, fast recovery, and short hospitalization period. [0003] However, there may be a paravalvular space after the release of the artificial valve, and at the s...

AI Technical Summary

Problems solved by technology

However, the existing technical solutions have high requirements for professional and technical personnel and are not scalable.

At the same time, the existing prediction scheme only predicts the surgical complications based on the state after the stent is released, and does not consider the impact of the surgical strategy adopted by the person during the TAVI operation (that is, the initial depth of the artificial valve release) on the surgical outcome

Therefore, there are inherent defects such as difficulty in promotion and incomplete prediction in existing technical solutions
