The Bentall procedure is a type of cardiac surgery involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined disease of the aortic valve and ascending aorta, including lesions associated with Marfan syndrome.
Catheter replacement of the aortic valve (called trans-aortic valve replacement or implementation [TAVR or TAVI]) is a minimally invasive option for those suffering from aortic valve stenosis. TAVR is commonly performed by guiding a catheter from the groin to the narrowed valve via the aorta using realtime x-ray technology.
Tubular ascending aortic replacement. The aorta is divided above the aortic valve and root. The avascular graft is then sutured to the aortic root. The form of the aortic valve may have been changed by this maneuver, it thus has to be carefully checked. Often stretching of a cusp becomes apparent at that point, and this will have to correct by ...
Valve-sparing aortic root replacement (also known as the David procedure) is a cardiac surgery procedure which is used to treat Aortic aneurysms and to prevent Aortic dissection. [1] It involves replacement of the aortic root without replacement of the aortic valve .
The aortic root is the portion of the aorta beginning at the aortic annulus and extending to the sinotubular junction. It is sometimes regarded as a part of the ascending aorta, [2] and sometimes regarded as a separate entity from the rest of the ascending aorta.
In patients with thoracic aortic disease involving the arch and descending aorta, it is not always possible to perform a completely endovascular repair. This is because head vessels of the aortic arch supplying blood to the brain cannot be covered and for this reason, there is often an inadequate landing zone for stent-graft delivery.
The aortic wall dilatation at the commissural level causes the cusps to effectively shorten and prevent them from converging during systole, which results in aortic valve incompetence. The arch is typically spared from the aneurysmal process, though it may involve the entire ascending aorta. The ectatic aorta may experience dissections.
[11] [10] Strong indications for CABG also include symptomatic patients and impaired left ventricle function. [10] CABG offers better results than PCI in left main disease and in CAD that affects multiple vessels, because of the protection arterial conduits offer to the native arteries of the heart, by producing vasodilator factors and ...
