  • Short-term outcome of ascending aorta replacement combined with total aortic arch fenestration technique for acute type A aortic dissection

    ObjectiveTo report our clinical experience and outcomes of thoracic endovascular aortic repair (TEVAR) for acute Stanford type A dissection using ascending aorta replacement combined with implantation of a fenestrated stent-graft of the entire aortic arch through a minimally invasive technique. MethodsFrom 2016 to 2020 in our hospital, 24 patients (17 males and 7 females, aged 45-72 years) with complicated Stanford type A aortic dissection, underwent replacement of the proximal ascending aorta with TEVAR. None of the patients with dissection involved the three branches of the superior arch, and all patients were replaced with artificial blood vessels of the ascending aorta under non-hypothermic cardiopulmonary bypass, preserving the arch and the three branches above the arch, and individualized stent graft fenestration. ResultsSurgical technical success rate was 100.0%. There was no intraoperative complication or evidence of endo-leak in 1 month postoperatively. Hospital stay was 10±5 d. During postoperative follow-up, the stent was unobstructed without displacement, the preserved branch of the aortic arch was unobstructed, and the true lumen of the descending aorta was enlarged. Conclusion This hybrid technique by using TEVAR with fenestrated treatment is a minimally invasive and effective method to treat high-risk patients with acute Stanford type A aortic dissection.

  • Mitral valve-in-valve technique: A case report

    [Abstract]A 70-year-old woman who was admitted to the hospital for post-cardiac surgery panic attack for 4 months. Eight months ago, she was admitted to a local hospital with 7 years of post-activity panic, which worsened for 2 months, and underwent mitral valve replacement+aortic valve replacement+tricuspid valvuloplasty+modified maze procedure+left auriculotomy. Four months after the operation, mitral valve damage appeared, and transcatheter mitral valve replacement was performed in our hospital by apical approach. A case report on the treatment of this patient is presented.
