Ascending aorta replacement in patients with coronary ostia localized above the sinotubular junction

  OBJECTIVES The study objective was to describe the technique and outcomes of original coronary ostial slide plasty in patients with anomalous coronary artery origin (ACAO) localized in the aneurysmal ascending aorta (AA) being replaced because of its isolated pathology and otherwise non-pathological aortic root. METHODS A total of 23 patients (median age 52 years) with the ascending phenotype of proximal aorta aneurysm and ACAO of at least 1 coronary artery localized in the AA being replaced underwent ostial slide plasty to transpose the ACAO to the respective sinus of Valsalva and, consequently, to allow an AA replacement with placement of the proximal anastomosis at the level of the sinotubular junction (STJ). In 15 patients, the aortic valve was bicuspid, and all but 3 patients presented with a relevant valve defect. In addition to remodelling the STJs (all patients), valve-sparing repair or replacement was performed in 12 and 8 patients, respectively. RESULTS No patient died during the entire follow-up (median 72, range 3–183 months). One patient required replacement of a recurrently insufficient valve that was repaired primarily using cusp patch plasty, but there were no further cardiac reoperations nor any re-interventions on the proximal aorta, aortic valve and/or coronary artery ostia. Two patients received peripheral coronary stents (8 and 7 years after surgery, respectively) due to coronary heart disease. CONCLUSIONS Transposition of the ACAO from the replaced AA into the normal sinus of Valsalva using the ostial slide plasty offers a simple and safe surgical option enabling a recreation of a durable STJ at the level of the anastomosis between the root and the aortic graft.
