Appointments. 201-447-8398. The David Procedure (also known as valve-sparing aortic root replacement) is a specialized procedure for aortic root aneurysms. The aortic root is special in that it contains both the aortic valve, as well as the origins of the coronary arteries.
How long is aortic root replacement surgery?
Aortic root surgery usually takes 4 to 6 hours, but the preparation and recovery may add several hours. This procedure is usually performed in the cardiothoracic operating room (OR).
What is Hemiarch replacement?
Hemiarch replacement is defined as the proximal arch repair beyond the level of the innominate artery without involving the arch vessels, and total arch replacement is the replacement of supra-aortic vessels as an island or individual branched grafts.
Can aortic root dilation be reversed?
Co-administration of captopril and C21 was able to reverse the aortic dilation (root, P<0.05; ascending aorta, P<0.01; Figure 1A), despite an increase in SBP in this group when compared with the captopril-treated TAC mice.
What is the frozen elephant trunk technique?
A relatively new approach is the frozen elephant trunk (FET) technique, which potentially allows combined lesions of the thoracic aorta to be treated in a 1-stage procedure combining endovascular treatment with conventional surgery using a hybrid prosthesis.
How successful is aortic root surgery?
Across the overall study population, aortic root surgery resulted in a 0.73 percent in-hospital mortality rate and a 1.4 percent stroke rate. Rates of death and stroke were similar among procedure types. There were no in-hospital deaths among patients receiving valve-preserving procedures.
Can you live 20 years after aortic valve replacement?
Pooled data from 85 studies estimated that 89.7% of people survived for two years after surgery, 78.4% at five years, 57.0% at 10 years, 39.7% at 15 years, and 24.7% at 20 years.
What is an elephant trunk procedure?
The elephant trunk procedure is a two-stage procedure used to treat extensive aneurysms involving both the ascending aorta and aortic arch, and the descending thoracic or thoracoabdominal aorta.
Why is frozen elephant trunk?
The so-called ‘frozen elephant trunk’ technique is adapted from the classical elephant trunk technique first described by H.G. Borst in 1983 and allows the repair of concomitant aortic arch and proximal descending aortic aneurysms in a single stage.
