We will compare the effective orifice area (smallest cross-sectional area of blood flow through a valve) of prosthetic valve placed at aortic position using two-dimensional and three-dimensional echocardiography and to find out which one will be showing accurate measurement.

Exclusion criteria

Exclusion criteria: Inadequate TEE images, patient refusal, Redo AVR, Contraindication to TEE probe, When CABG or multiple valve repair/replacement to be done as part of surgery, presence of more than mild mitral regurgitation or stenosis, intracardiac or extracardiac shunt, Second run on CPB, LVEF less than 40%

Design outcomes

Primary

MeasureTime frame
To compare and correlate the effective orifice area by 2D and 3D echocardiography of prosthetic valves implanted at aortic position.Timepoint: Transesophageal echocardiography after induction(before initiation of cardiopulmonary bypass), post valve placement(after coming off from Cardiopulmonary bypass) Trans thoracic echocardiography 48hrs after surgery and before discharge of the patient.—

Secondary

MeasureTime frame
1. To correlate between EOA obtained by 3D echocardiography with less flow dependent parameters like DVI, AT, AT/ET 2. To compare effective orifice area obtained by 3D echocardiography with previously published EOA of prosthetic aortic valve. 3. To correlate intraoperative effective orifice area (EOA) in the intraoperative transesophageal echocardiography (TEE) & after 48 hours of surgery with transthoracic echocardiography (TTE).Timepoint: Transesophageal echocardiography after induction(before initiation of cardiopulmonary bypass), post valve placement(after coming off from Cardiopulmonary bypass) Trans thoracic echocardiography 48hrs after surgery & before discharge of the patient.—
