Valve-sparing aortic root replacement removes damaged portions of your aorta, but allows you to keep your native aortic valve. It’s suitable for some people under age 65 who need surgery to treat an aortic aneurysm but have a healthy aortic valve.

During Valve Sparing Root Replacement (also called the David Procedure, to give credit to the surgeon who initially conceived the operation, Tirone David, MD), the patient's aortic valve is kept (although it may be repaired and reimplanted) and reconnected to a new section of aortic tissue.

The valve-sparing aortic root replacement allows for direct narrowing of enlarged aortas, which change the fluid dynamics of outbound blood from the heart, while preserving the natural tissues of the aortic valve, which means the patient does not have to rely on anticoagulants.Common features of both techniques of the replacement process are the clamping of the aorta and the …

2022年4月21日 · Valve-sparing root replacement (VSRR) is a good choice if your aortic valve is working well. For example, you don’t have severe regurgitation or calcification. It’s often the best choice for younger people who have aortic root aneurysms associated with genetic syndromes. VSRR replaces your aortic root but not your aortic valve.

2024年11月27日 · Valve-sparing aortic root repair (top-right image) replaces the enlarged section of the aorta with an artificial tube, called a graft. The aortic valve stays in place. In aortic valve and aortic root replacement (bottom-right image), the aortic valve and a part of the aorta are removed.

2025年1月29日 · Key steps in the modified valve-sparing aortic root replacement procedure. (A) The aortic valve is mobilized so the entire annulus can be housed within the tube graft. Valve sutures are passed from inside the ventricular outflow tract and through the polyester tube graft. (B) The sutures are tied down around a Hegar dilator appropriate to the ...

In this case, the re-implantation procedure can be performed to reconstruct the aortic root, followed by excision of the native valve and replacement with a stented bioprosthesis as one would for a conventional aortic valve replacement.

Aortic valve-sparing root replacement is an important procedure for addressing the dilation of aortic root aneurysms for select patients.

Surgeons in Penn Medicine’s Aorta Center have unmatched expertise repairing thoracic aortic aneurysms that occur where the heart and aorta meet (the aortic root). We offer a procedure that maintains a person’s native aortic valve.

Valve-sparing aortic root replacement (VSARR), also called the David Procedure, is a specialized surgical procedure that repairs the aortic root while preserving the aortic valve. One of four valves in the heart, the aortic valve pumps oxygenated blood to the rest of the body.

Patients in the Bentall group underwent aortic root replacement with a composite valve graft using standard methods. Aortic root reconstruction was made by reduction of the sinotubular junction (n=27) or sinotubular junction+annulus (n=11), or the reimplantation or remodeling technique (David I, n=7; David II, n=3).

2023年5月30日 · Valve-sparing aortic root replacement has excellent long-term outcomes, with low mortality and reintervention rates. Concomitant leaflet repair and bicuspid valve disease are the only long-term factors associated with reintervention. Results from up …

A valve-sparing aortic root replacement surgery (also called the David procedure) repairs aortic aneurysms at the aortic root. Sparing the aortic valve during aortic root replacement improves long-term survival rates and decreases the risk of complications.

A valve-sparing aortic root replacement, also called the David procedure, repairs aneurysms at the aortic root. We replace your aorta at the aortic root. But we keep your natural heart valve in place. That prevents you from needing a valve replacement procedure later on. UVA Health's Aortic & Aneurysm Expertise

The aim of these valve-sparing root replacement (VSRR) procedures is to preserve the functionality and superior hemodynamics of the native aortic valve while replacing the dilated or dissected aortic root—thus avoiding the typical complications associated with mechanical or biological prostheses.

Aortic valves can be repaired through a surgery called valve-sparing aortic root replacement, also know as the David Procedure. Aortic root replacement may be an option for patients who have a condition called bicuspid aortic valve, an aortic aneurysm or other conditions that result in …

2023年3月10日 · In patients whose aortic root—the portion of the aorta attached to the left ventricle, where the heart’s aortic valve resides—requires surgical replacement because of an aneurysm, it is ideal to replace the root but to leave the valve intact.

Reimplantation of the aortic valve provides excellent clinical outcomes and stable aortic valve function for decades in patients with aortic root aneurysm and normal or mildly diseased aortic cusps. See Commentaries on pages 79 and 81.

2023年8月10日 · Retaining your own valve via a valve sparing aortic root replacement (VSRR) has the benefit of not requiring lifelong blood thinners, and will have a much longer lifespan than aforementioned valve options. You will also have a lower risk of infection and the blood flow across the valve will be more physiological. Am I suitable for a VSRR?

2014年8月4日 · Only after gaining enough experience, we moved to minimally access valve sparing aortic root replacement (David procedure). This ‘step-by-step’ method of progressing gradually from simpler operations to technically more complex aortic root surgery is crucial to maintaining low complication rates.

The valve-sparing aortic root replacement is a surgical treatment for aortic root aneurysms. With this method, the aneurysm is repaired while the patient’s own aortic valve is preserved.

2025年2月1日 · This study compared long-term survival and reintervention rates between Valve-Sparing Root Replacement (VSRR, n = 244) and Aortic Root Replacement (ARR, n = 499) in 743 patients undergoing Type A ...

3 天之前 · In cases where the aortic valve is also compromised, surgeons may perform a valve-sparing procedure or replace it with a mechanical or biological valve. The choice between repair and replacement depends on various factors, including the patient's overall health, age, and specific anatomical considerations.

“Valve-sparing root replacement using the reimplantation technique is well established for treatment of trileaflet aortic valves and is increasingly being used for bicuspid aortic valves, including in those with significant aortic insufficiency,” notes Dr. Lau.

Valve sparing aortic root replacement allows patients to keep their aortic valve during a replacement of the of the aortic root, which attaches the aorta to the heart. Prior to this procedure's approach, patients also needed an aortic valve replacement.

2025年1月8日 · dilation of the ascending aorta distal to the sinotubular junction is characteristic, with relative sparing of the aortic root. ... aortic valve replacement is performed and occurs in a younger age group than in patients with tri-leaflet valve stenosis. Aortic root replacement is also required in 30% of patients undergoing valve replacement 9.

2025年2月5日 · Inspiris Resilia performance after bicuspid aortic valve replacement. One study [] compared the clinical outcomes of bicuspid and tricuspid SAVR using the Inspiris Resilia valve.The valve showed excellent outcomes at 5 years with no structural valve deterioration and very low rates of paravalvular (0.7%) and transvalvular regurgitation (2.9%).
