This video is unavailable. Aortic valve sparing operations are complex operative procedures and require long cardiopulmonary bypass and aortic clamping times, which often increase the risk of post-pump coagulopathy. However, inherent complications do arise when using mechanical aortic prostheses. Sarsam MA, Yacoub M. Cusp repair in aortic valve reconstruction: does the technique affect stability?. Remodeling of the aortic valve anulus. This procedure requires aortic valve replacement, usually with a mechanical prosthesis, and as such is accompanied by lifelong anticoagulant treatment.
Aortic valve sparing operations were developed to preserve the native aortic valve during surgery for aortic root aneurysm as well as surgery for. Aortic valve repair and valve sparing procedures enable restoration of competence in regurgitant aortic valve, and thus to avoid the risks related to valve.
Aortic Valve Sparing Operations A Review
Aortic valve-sparing procedures are alternative options to aortic valve replacement in patients with aortic root aneurysm and/or severe aortic.
The main cause of late failure is probably degeneration of the aortic cusps but more information is needed to confirm this observation.
J Heart Valve. The Hospital 12 de Octubre's ethics committee approved our study, and all patients gave informed consent to use their clinical information. Choose your language. MMCTS 24, views.
Our reservation regarding that graft is its shape. Midterm outcome of valve-sparing aortic root replacement in inherited connective tissue disorders.

Our study with patients undergoing aortic valve reimplantation is one of the largest published, and the results obtained are comparable to those from other institutions with experience using this method.
Long term results of aortic root repair using the reimplantion technique. The diameter of the aortic annulus is surprisingly small in patients with normal aortic valves [ 14 ] and surgeons must have this knowledge to determine when the aortic annulus is dilated.

Reimplantation of the aortic valve, first described by. As with any heart valve-preserving procedure, patient selection and surgical expertise are The term aortic valve-sparing operation (AVS).
Between March and Octoberpatients with aortic root aneurysms underwent valve sparing surgery using the technique described by David
Valve-sparing aortic root replacement in Loeys-Dietz syndrome. This study produced two interesting conclusions: first, that aortic valve reimplantation using the David type V method is the most commonly used procedure, and second, the early results from the study were similar to those obtained using the Bentall method, in spite of it being a more complex procedure.
Only 1 patient was re-operated on for severe AoR during follow-up, 5 years after the surgery. An aortic ring to standardise aortic valve repair: preliminary results of a prospective multicentric cohort of patients.

|In our study, prolapsed aortic leaflets were corrected after valve reimplantation in 29 patients using some of the techniques described in Methods.
Keywords: Aortic root aneurysm, Aortic insufficiency, Aortic valve sparing. We continue to use both techniques and try to match the procedure to the pathology of the aortic root. Aortic root remodelling: Ten-year experience with patients. Prolapse of one or more cusps does not preclude a good repair if the cusp tissue is found to be of good strength at surgery. This technique prevents the need for chronic anticoagulation treatment as well as the complications arising from mechanical prostheses, and it should be the treatment of choice for young patients.
Valve Sparing or Valve Preserving Surgery (Reimplantation Surgery) Cleveland Clinic
The reimplantation valve-sparing aortic root replacement method is a surgical treatment for aortic root aneurysms. With this method, the aneurysm is repaired. During Valve Sparing Root Replacement (also called the David Procedure, to give credit to the surgeon who initially conceived the operation, Tirone David, MD).

Table 1 Freedom from reoperation and freedom from moderate and severe aortic insufficiency after aortic valve sparing operations. However, these techniques are technically demanding and long-term results are highly dependent on perfect intraoperative restoration of valve function.
Conclusions Short- and mid-term results with the reimplantation technique for aortic root aneurysms are excellent. Interestingly, we have found that age had a protective effect against the development of late aortic insufficiency after reimplantation of the aortic valve [ 16 ], suggesting that elastic aortic cusps probably have greater adaptability to a rigid root than the more sclerotic ones often seen in older patients.

|Two patients died during the first year following surgery: 1 due to a ruptured aneurysm of the abdominal aorta, and 1 due to pulmonary thromboembolism.
Next, the aortic valve is re-implanted into position within the aorta graft. Congresses Only available in Spanish. J Heart Valve. We performed an intraoperative transoesophageal echocardiogram on all patients in order to evaluate the aortic valve. A classification system for the bicuspid aortic valve from surgical specimens.
