An antegrade prolapse into the aortic arch causes obstruction of the great supra aortic vessels, (2) whereas a retrograde prolapse into the LV causes
aortic regurgitation (3) and obstruction of the coronary artery.
Led by Cleveland Clinic cardiologist Murat Tuzcu, MD, the study of the Direct Flow Medical system resulted in low rates of mortality and stroke, as well as minimal
aortic regurgitation.
Once the new valve is put into place, it is expanded to push the old valve's leaflets (the human aortic valve has three leaflets--delicate flaps--that stop blood flowing back into the left ventricle of the heart) out of the way and the tissue in the .replacement valve takes over the job of regulating blood flow.The goal also is to prevent
aortic regurgitation, a condition that occurs when the aortic valve doesn't close tightly.
We believe that transesophageal echocardiography is an extremely useful tool, and it is now used widely for the detection of aortic diseases (5) because the entire thoracic aorta and left main coronary ostium can be viewed, and any
aortic regurgitation can be easily seen.

aortic regurgitation and a review of the literature," Cardiovascular Pathology, vol.
Echocardiography showed mild
aortic regurgitation without aortic stenosis and aneurysmatic dilatation of ascending and descending aorta.
Ishikawa defined the four most important complications of TA as retinopathy, secondary hypertension,
aortic regurgitation, and aneurysm formation, each graded as mild, moderate, or severe [5].
Aortic regurgitation was present in 32 patients (mild, 16; moderate, 14; severe, 2).
He presented with worsening shortness of breath (NYHA 111) and was found to have severe calcific aortic stenosis and moderate
aortic regurgitation, but no significant coronary artery disease.
Key words: Aortic stenosis,
Aortic regurgitation, Aortic insufficiency, Diagnosis, Management
She also had
aortic regurgitation, and her left ventricle ejection fraction was estimated to be around 36%.
Cardiovascular examination showed a water-hammer pulse (Corrigan's sign), prosthetic heart sounds, an ejection systolic murmur, and an early diastolic murmur consistent with
aortic regurgitation. Respiratory examination was unremarkable, and splenomegaly (1-cm enlargement) was detected in the abdomen.
