左心耳 (LAA) 评估对于为房颤 (AF) 患者选择最佳的 LAA 封堵器非常重要。日本患者的左心耳特征尚未得到研究。我们比较了导管消融前的 212 名日本房颤患者和美国 (US) 接受左心耳封堵术的 119 名房颤患者的左心耳大小和形态。我们通过经食管超声心动图测量了所有患者的左心耳开口尺寸和深度，并通过多排心脏计算机断层扫描确定了日本患者的左心耳形态类型，通过左心耳血管造影确定了美国患者的左心耳形态类型。日本患者的左心耳最大开口尺寸显着大于美国患者（22.6±±4.1 mm vs. 21.5±±3.5 mm，P =±0.02）。此外，在阵发性和非阵发性 AF 组中，日本患者的最大尺寸和经体表面积校正的深度均大于美国患者。两组中约 75% 的患者显示最大尺寸的角度为 0° 或 135°。日本患者常见的左心耳形态类型为“花椰菜”和“鸡翅”，美国患者常见的左心耳形态类型为“仙人掌”和“风向袋”。在这项研究中，日本患者的左心耳尺寸比美国患者大。由于最大左心耳尺寸是在相同角度下获得的，因此美国患者的左心耳测量方法可以适用于日本患者。
Left atrial appendage (LAA) evaluation is important to select the optimal LAA closure device for patients with atrial fibrillation (AF). The LAA characteristics of Japanese patients remain uninvestigated. We compared the LAA size and morphology between 212 Japanese AF patients before catheter ablation and 119 AF patients undergoing LAA closure in the United States (US). We measured the LAA ostial dimension and depth by transesophageal echocardiography in all patients and determined the LAA morphology types of Japanese patients by multidetector cardiac computed tomography and those of US patients by LAA angiography. The maximum LAA ostial dimension was significantly larger in Japanese patients than in US patients (22.6 ± 4.1 mm vs. 21.5 ± 3.5 mm, P = 0.02). Also, Japanese patients had larger maximum dimension and depth corrected by body surface area than US patients in both paroxysmal and nonparoxysmal AF groups. The angle showing the maximum dimension was 0° or 135° in approximately 75% of patients in both groups. The common LAA morphology types were “cauliflower” and “chicken wing” in Japanese patients and “cactus” and “windsock” in US patients. In this study, Japanese patients had a larger LAA size than US patients. Because the maximum LAA dimension was obtained at the same angles, the LAA measurement method for US patients can be applicable to Japanese patients.
