| 目的 观察不同Sievers分型二叶主动脉瓣（BAV）患者的超声心动图表现特征。方法 回顾性分析121例BAV患者的临床及超声心动图检查资料。Sievers分型分为0型（无嵴）、1型（有一嵴）和2型（有双嵴），其中1型分为3个亚型：1（L-R）亚型（左冠瓣与右冠瓣融合），1（R-N）亚型（右冠瓣与无冠瓣融合），1（N-L）亚型（左冠瓣与无冠瓣融合）。比较不同Sievers分型BVA患者主动脉内径超声测量值。结果 121例中，3例（3/121，2.48%） Sievers分型为0型；118例（118/121，97.52%）为1型，其中1（L-R）亚型80例（80/121，66.12%），1（R-N）亚型33例（33/121，27.27%），1（N-L）亚型5例（5/121，4.13%）；无2型患者。1（R-N）亚型主动脉瓣环及窦部内径均小于1（L-R）亚型（P=0.01、0.02），1（L-R）、1（R-N）及1（N-L）亚型间主动脉瓣环、窦部、窦管结合部及升主动脉近端内径差异均无统计学意义（P均>0.05）。结论 Sievers分型为1（L-R）亚型在BAV患者中最常见，且超声心动图所见主动脉瓣环及窦部扩张较1（R-N）亚型更明显。 |

| Objective To observe echocardiographic characteristics of bicuspid aortic valve (BAV) with Sievers classification. Methods Clinical and echocardiography data of 121 patients with BAV were retrospectively analyzed. According to Sievers classification, the patients were divided into type 0 (no raphe), type 1 (one raphe) or type 2 (two raphes). BAV of type 1 was further divided into three subtypes, including 1(L-R) subtype (the raphe positioned between the left and the right coronary sinuses), 1(R-N) subtype (the raphe positioned between the right coronary sinus and non-coronary sinus) and 1(N-L) subtype (the raphe positioned between the left coronary sinus and non-coronary sinus). The diameters of aorta in BAV patients with Sievers classification obtained with echocardiography were compared. Results There were 3 patients (3/121, 2.48%) of type 0 and 118 patients (118/121, 97.52%) of type 1 BAV. In patients of type 1 BAV, there were 80 cases (80/121, 66.12%) of subtype 1 (L-R), 33 (33/121, 27.27%) of subtype 1 (R-N) and 5 (5/121, 4.13%) of subtype 1 (N-L). There was no type 2 patient among these 121 cases. The diameters of the annulus and sinus of Valsalva in subtype 1 (R-N) BAV patients were less than those in subtype 1 (L-R) BAV (P=0.01, 0.02). There was no significant difference of the diameters of the annulus, sinus of Valsalva, sinotubular junction nor the proximal ascending aorta among different subtypes of BAV (all P>0.05). Conclusion Subtype 1(L-R) is more common in BAV patients, which often associated with larger diameters of annulus and sinuses of Valsalva than subtype 1(R-N) on echocardiography. |
