Intraoperative Assessment Versus Preoperative Multidetector Computed Tomography (MDCT) for Aortic Valve Annular Sizing in Surgical Aortic Valve Replacement (SAVR)"
Intraoperative Assessment Versus Preoperative Multidetector Computed Tomography (MDCT) for Aortic Valve Annular Sizing in Surgical Aortic Valve Replacement (SAVR)"
This study aims to understand why there may be differences between the measurements of the aortic valve taken before and during surgery. Specifically, it will compare the valve size suggested by a CT scan (Computed Tomography) with the size measured during the operation using surgical tools. This will help determine which method is more accurate for selecting the right valve size in patients undergoing SAVR (Surgical Aortic Valve Replacement ).
Inclusion Criteria:
Patient age 18 years or older
All patients with isolated severe Aortic Stenosis (AS) considered eligible for Surgical Aortic Valve Replacement (SAVR) according to the current 2023 European Society of Cardiology/European Association for Cardio-Thoracic Surgery (ESC/EACTS) guidelines for management of Valvular Heart Disease (reference 8) will be enrolled.
Patient is willing to comply with study procedures and is available to return to the center for follow-up visits.
Informed consent documentation signed and dated confirming that the patient has been adequately informed of all aspects related to his/her participation in the clinical study and is willing to participate.
Exclusion Criteria:
Bicuspid aortic valve anatomy Moderate to severe aortic valve regurgitation Multivalvular disease Redo Surgical Aortic Valve Replacement Ascending aorta aneurysm Aortic root enlargement Chronic Kidney Disease with estimated Glomerular Filtration Rate less than 30 milliliters per minute Body Mass Index greater than 30 kilograms per square meter Inadequate Multidetector Computed Tomography images
