You are incorrect - the best diagnosis in our patient is coarctation of the aorta, bicuspid aortic valve and aortic regurgitation.
Your choice: Coarctation of the aorta, aortic valve stenosis and aortic regurgitation
As long as the patient's cardias output is not less than normal, significant aortic valve stenosis causes a longer and louder systolic murmur than is present in our patient.
