To delineate the precise anatomic abnormalities of the interventricular septum (IVS), mitral valve (MV), and left ventricular posterior wall (LVPW) in patients with hypertrophic cardiomyopathy (HCM), we used axial biventriculography (BVG) (hepato-clavicular projection: angled BVG) to examine 17 patients with HCM and four with concentric hypertrophy due to systemic hypertension. We also examined 9 of these 21 patients with conventional left anterior oblique (LAO) BVG (non-angled BVG). The IVS and along axis of the LV cavity when measured by angled BVG were significantly longer than when measured by non-angled BVG. The IVS, MV, and LVPW were better seen in profile in angled than in non-angled BVG. In two patients with HCM with obstruction (HOCM), systolic anterior motion of the anterior leaflet of the MV was readily identifiable with angled BVG, which is usually not the case with non-angled BVG. Thus, angled BVG is superior to conventional LAO BVG in the angiographic assessment of patients with HCM.
为了明确肥厚型心肌病（HCM）患者室间隔（IVS）、二尖瓣（MV）和左心室后壁（LVPW）的确切解剖异常，我们采用轴向双心室造影（BVG）（肝锁骨位投影：成角BVG）检查了17例HCM患者和4例因系统性高血压导致的同心性肥厚患者。我们还对这21例患者中的9例进行了传统的左前斜位（LAO）BVG（非成角BVG）检查。成角BVG测量时，IVS及左心室腔的长轴明显长于非成角BVG测量时。与非成角BVG相比，成角BVG能更好地显示IVS、MV和LVPW的轮廓。在2例梗阻性肥厚型心肌病（HOCM）患者中，成角BVG能清晰显示MV前叶的收缩期前向运动，而在非成角BVG中通常无法观察到。因此，在HCM患者的血管造影评估中，成角BVG优于传统的LAO BVG。
