Unsupported Reduction Ascending Aortoplasty: Fate of Diameter and of Windkessel Function

Reduction Aortoplasty for the Ascending Aortic Aneurysm With Aortic Valve Disease - Does Bicuspid Valve Matter? -

“…1, 8 However, controversies still exist with regard to indications, techniques and long-term results of RAA. [5][6][7][8] Previous studies have demonstrated that in-hospital mortality associated with RAA and aortic valve replacement ranged from 1.5 to 11.8% and bleeding complications related to reduction suture were rare. 5-7, 14 The present study also demonstrated low operative mortality and acceptable morbidities after RAA.…”

“…17, 18 It has also been suggested that the elasticity of the ascending aorta, known as the Windkessel function, which enables the ascending aorta to store energy and volume during systole and release it during diastole, is diminished after external wrapping. 6 In the present study, we performed RAA without external support in all patients. However, no patient experienced aortic dissection, which frequently occurred in patients with aortic aneurysm, 19,20 and rupture and aorta-related reoperation during a period of 74 (1-190) months after surgery.…”

“…In contrast to AAR, AoP preserves the Windkessel function. 25 The results of AoP have been reported to be satisfactory, safe, and durable if the diameter can be adequately reduced to about 3.6 cm. 26 It should be performed in patients with borderline dilatation 27 (Table E4, Figure 2) and not in patients with an insufficient valve 28 ; AoP can also be performed in those with post-stenotic AA dilatation and in elderly patients.…”

Early Prognosis of Reduction Ascending Aortoplasty in Patients With Aortic Valve Disease: A Single Center’s Experience

“…The Windkessel function helps to dampen the fluctuation in blood pressure over the cardiac cycle and assists in the maintenance of organ perfusion during diastole when cardiac ejection ceases. It is suggested that unsupported RAA may preserve the Windkessel function of the ascending aorta [37]. In addition, the wrap may dislocate and compromise the origin of the aortic arch vessels [38].…”
