P307. Simplified Reimplantation: a Bailout in Fragile Aortic Wall Remnants

Sheraton Times Square 

Objective: to describe the simplified reimplantation technique, to discuss its range of application and report the early echocardiographic and computed tomography angiography (CTA) results of the technique.
Case Video Summary: 13 patients underwent the simplified reimplantation procedure between December 2022 and November 2023, 2 bicuspid and 11 tricuspid aortic valve patients. The technique was applied to cases of extremely diseased root wall where the aortic remnants were judged fragile and unsuitable for suturing to the Dacron.
The simplified reimplantation was performed as follows: the aortic wall remnants are completely removed. Twelve-pledgeted sutures are placed along the circumference of the virtual basal ring and then passed at the established level of the Valsalva graft (hemostatic suture). The commissures are fixed at the new sinotubular junction with a horizontal pledgeted suture. One pledgeted suture is added vertically within each interleaflet triangle to anchor the aortic valve to the graft. The rest of the procedure is carried out in the standard fashion.
Early echocardiographic results showed none or trivial AR in all patients, no significant gradient. Early postoperative CTA images showed a re-established morphology of the root with a preserved separation of the sinuses of Valsalva. The stabilization of the interleaflet triangles allows a better distribution of the hemodynamic stress along the whole commissure (not only on the tip of the commissure) and avoids blood flow between the commissure and the Dacron.
Conclusions: the simplified reimplantation technique is an excellent bailout strategy for valve sparing in patients with fragile and damaged aortic wall remnants. The early echocardiographic results are excellent. The CTA images show a re-established physiological root morphology and comparable to the standard technique. Longer follow up is needed to evaluate long term results.
