Inclusion Criteria

Inclusion Criteria for Aortic Valve:

1. Patient must be 18 years or older.

2. Patient must provide written informed consent prior to study procedures.

3. STS scores should be less than 4 percent (Low Risk)

4. Patient must agree to attend all follow-up assessments for up to 5 years and is willing to comply with specified follow-up evaluations at clinical investigational sites that are participating in the Dafodil-1 study.

5. Diagnosed with aortic disease requiring valve replacement based on pre-operative evaluation (Medical history, physical examination, echocardiography and CBC).

6.Patient has significant Aortic stenosis or Aortic regurgitation or patient is subjected for Aortic Valve replacement due to combine aortic lesion (stenosis and regurgitation).

(Reference: European society of Cardiology (ESC)/ American Society of Echocardiography (ASE) Guidelines - 2017)

7. Scheduled to undergo planned aortic valve replacement with or without concomitant bypass surgery or other valvular surgeries.
