Aortic Valve Replacement for Moderate Aortic Stenosis With Left Ventricular Decompensation Early Feasibility Study

Aortic Valve Replacement for Moderate Aortic Stenosis With Left Ventricular Decompensation Early Feasibility Study

Obtain safety and effectiveness data to support expansion for aortic valve replacement to include patients with moderate aortic stenosis and left ventricular decompensation.

Single-center prospective study. Subjects with moderate aortic stenosis and left ventricular decompensation will receive aortic valve replacement by the Ross procedure.

Inclusion Criteria:

• Moderate aortic stenosis, defined by transthoracic echocardiograph
• Max aortic velocity less than 4.0 m/sec.
• Mean aortic gradient less than 40.0 mmHg.
• 1.0 cm2 < Aortic Valve Area < 1.5 cm2.
• Left ventricular decompensation

Exclusion Criteria:

• Not suitable for the Ross procedure.
• Documented history of cardiac amyloidosis.
