Brief Summary

Detailed Description

DESIGN OF THE STUDY This is a retrospective and prospective observational, non-profit study. All consecutive patients who have entered the TAVI pathway at this hospital (Azienda Ospedaliera Universitaria di Ferrara) since January 2016 will be included in the study. The study does not involve any alteration or modification of routine clinical practice and does not require any center or operator to use specific devices. It involves the collection of pre- and post-procedural data from patients who enter the TAVI pathway. All patients will be re-contacted to confirm clinical follow-up via telephone to gather information on any adverse events that may have occurred in the years following TAVI (at 1, 5, and 10 years post-TAVI). For each patient enrolled in the study, an anonymous case report form (CRF) will be completed. INCLUSION AND EXCLUSION CRITERIA All patients referred to the valve disease outpatient clinic with a diagnosis of severe aortic stenosis who are candidates for TAVI will be asked to participate in the study and sign the consent form as part of the process to schedule the required investigations. All consecutive patients with a diagnosis of severe aortic stenosis who, since January 2016, who have completed all the clinical and instrumental investigations required by the hospital protocol prior to receiving TAVI will be enrolled. Therefore, all patients with a diagnosis of severe aortic stenosis who have been indicated for TAVI and have completed the following will be included in the study: 1. Pre-TAVI transthoracic echocardiogram 2. ECG and cardiology consultation to confirm TAVI eligibility 3. Thoraco-abdominal aortic CT angiography 4. Coronary angiography +/- angioplasty +/- valvuloplasty. The decision to perform valvuloplasty or angioplasty prior to TAVI remains at the discretion of the operating physician. This protocol does not alter clinical judgment or daily routine in any way. Inclusion criteria: Age \>18 years Signing of the consent form Diagnosis of severe aortic stenosis with an indication for TAVI Completion of the required TAVI pathway exams (ECG and cardiology consultation, echocardiogram, thoraco-abdominal aortic CT angiography, coronary angiography) Exclusion criteria: Lack of signed consent form Inability to complete follow-up CONSENT ACQUISITION AND STUDY ENROLLMENT When a patient meeting the inclusion and exclusion criteria is identified, the investigator or their delegate will explain the study, its procedures, and objectives to the patient. If the patient agrees to participate, they must sign the consent form. The investigator is responsible for keeping a copy of the consent form and providing one to the patient. After consent is signed, all baseline patient characteristics and procedural details will be documented in the designated CRF. In line with current recommendations for clinical study management, a unique identifier will be assigned to each patient upon creation of the CRF to ensure traceability. Only the investigator will be able to link this identifier to the patient for follow-up purposes. No one other than the center's investigator will have access to identifying patient information in the CRF. The study also includes a retrospective component, for which patient data will be used in anonymized form. In the retrospective phase, consent will also be obtained for data use, except in cases where patients are deceased or unreachable. In the former case, consent from family members will be sought, while in the latter, the patient will not be included in the study. The Principal Investigator (PI) or their delegate will collect the following information for each enrolled patient, which will be recorded in the CRF. Documentation of adverse events should be as thorough as possible to enable assessment by the independent adverse event adjudication committee. ASSESSMENTS PERFORMED IN THE TAVI PATHWAY As part of standard clinical practice, all patients entering the TAVI pathway will undergo the following: * Electrocardiogram and cardiology consultation * Complete transthoracic echocardiogram * Thoraco-abdominal CT angiography * Coronary angiography +/- angioplasty +/- valvuloplasty PROSTHESIS IMPLANTATION INFORMATION During the TAVI hospitalization, the following clinical information will be collected for each enrolled patient: Type of implanted prosthesis Procedural details (fluoroscopy time, amount of contrast media, use of temporary pacemaker) Information on any procedural or post-procedural complications according to VARC criteria (see subsequent definitions) POST-TAVI ASSESSMENTS Following TAVI, as per routine practice, patients will undergo the following evaluations before discharge (at our hospital in case of in-service procedures or at the TAVI-performing center): Electrocardiogram Transthoracic echocardiogram Clinical assessment to rule out post-procedural complications CLINICAL FOLLOW-UP All TAVI patients are routinely re-evaluated 1-3 months post-procedure at the Valve Disease outpatient clinic, where they receive: Clinical assessment Electrocardiogram Transthoracic echocardiogram TELEPHONE FOLLOW-UP All patients enrolled in the study will be contacted by telephone at 1, 5, and 10 years post-TAVI to gather information on any adverse events that may have occurred during the follow-up period.
