  • Surgical Treatment of Bicuspid Aortic Valve Combined with Toracic Aortic Dilation

    ObjectiveTo analyze the clinical characteristics and surgical treatment of bicuspid aortic valve combined with thoracic aortic dilation. MethodsWe retrospectively analyzed the clinical data of 68 patients of bicuspid aortic valve combined with thoracic aortic dilation underwent surgical treatment in our hospital between January 2010 and June 2014. There were 47 males and 21 females at age of 26-77(44.5±16.3) years. Different surgical treatments including Wheat procedure(n=22), aortic valve replacement+ascending aortoplasty(n=10), Bentall procedure(n=13), aortic valve replacement+ascending aortic replacement+right hemi aortic arch replacement(n=13), Bentall procedure+ascending aortic replacement+right hemi aortic arch replacement(n=8), Bentall procedure+ascending aortic replacement+total arch replacement+stented elephant trunk(n=2) were carried out according to the type. ResultsAll 68 patients underwent surgical treatment. The mortality in hospital is at 4.4%(3/68). The postoperative complications were neurological and mental complications(n=3), pneumonia(n=2), and exploratory thoracotomy(n=2). We followed up 63 patients for 6 months to 4 years. A total of 62 patients were well without reoperation except one death at the end of following-up 2 years. ConclusionBicuspid aortic valve combined with thoracic aortic dilation has diversiform clinical characteristics. The surgical treatment should be chosen according to the aortic valve and thoracic aortic lesion characteristics.

  • Study on the surgical indication for patients with simple ascending aortic dilatation

    ObjectiveTo compare the ascending aortic diameter and postoperative outcomes of patients with simple ascending aortic dissection or simple ascending aortic dilatation and to study the reliability of the surgical indication in present guideline for Chinese patients with ascending aortic dilatation.MethodsThe clinical data of patients with aortic aneurysm and aortic dissection who underwent surgery at Beijing Anzhen Hospital, Capital Medical University from 2010 to 2017 were retrospectively reviewed. After exclusion of patients with Marfan syndrome, heart valve and other diseases, 139 patients were divided into two groups: a simple ascending aorta dilatation group (56 patients) and a simple ascending aortic dissection group (83 patients). The ascending aortic diameter and postoperative outcomes of two groups were compared. ResultsThe inner ascending aortic diameter (57.30±9.41 mm vs. 50.72±9.53 mm, P <0.001) and the inner ascending aortic diameter index (31.12±5.38 vs. 27.22±6.40, P<0.001) in the simple ascending aorta dilatation group were significantly greater than those in the simple ascending aortic dissection group. For male patients, the results were similar (60.28±10.80 mm vs. 47.40±6.53 mm; 30.00±6.33 vs. 23.60±3.72, both P<0.001). But for the female patients, there was no significant difference between the two groups (54.90±7.47 mm vs. 53.81±10.84 mm; 32.03±4.37 vs. 30.58±6.56, both P>0.05). The mortality, the incidence of tracheotomy and postoperative reopen rate in the simple ascending aortic dissection group were higher.ConclusionIn this study, the inner diameter of the ascending aorta in the group of ascending aorta is mostly < 5.5 cm. In our opinion, the present surgical indication for Chinese patients with ascending aortic dilatation is not enough. In the future clinical studies, we also need to find more reasonable surgical indications.

  • Characteristics of bicuspid aortic valve aortopathy and association with valvular phenotype and dysfunction

    ObjectiveTo summarize the characteristics of bicuspid aortic valve (BAV) aortopathy and analyze the association between aortopathy and BAV phenotype and patterns of valvular dysfunction.MethodsClinical data of 191 patients who underwent the first aortic valve replacement in Fuwai Hospital from June 2017 to March 2018 were retrospectively analyzed, including 143 males and 48 females with an average age of 53.91±12.52 years. All patients underwent multidetector computed tomography (MDCT) and echocardiography before the operation, excluding patients with aortic coarctation. The BAV aortopathy phenotype was classified during operation. The characteristics of BAV aortopathy were analyzed by cluster and artificial analysis. BAV anatomic phenotype was divided into two types according to the direction of valve opening: BAV-AP and BAV-LR.ResultsFour distinct BAV aortopathy phenotypes were identified: a common type (n=70, 36.6%), with no dilation or mild dilation of aorta; a root type (n=24, 12.6%), with predominant dilatation of aortic sinus; an ascending aorta type (n=72, 37.7%), with predominant dilatation of ascending aorta; an arch type (n=25, 13.1%), with predominant dilatation of aortic arch dilatation. The root type was mainly in young patients, while the arch type was mainly in elderly patients (P<0.05). BAV-AP and aortic insufficiency were most prevalent in root type, while BAV-LR and aortic stenosis were most prevalent in arch type (P<0.05). There were 111 (58.1%) patients undergoing aortic surgery, and the coincidence rate of BAV aortopathy phenotype and aortic surgery was 80.6%.ConclusionAccording to the location of aortic dilation, BAV aortopathy can be divided into four types. There is an association between BAV aortopathy and valvular phenotype and dysfunction.
