A 35-year-old white female patient presented with radiation-induced constrictive pericarditis. Intraoperative transesophageal echocardiography revealed a uniphasic diastolic flow pattern. This pulmonary flow pattern reverted to a normal biphasic systolic/diastolic profile immediately following radical pericardiectomy. This abnormal flow pattern was previously described as typical for restrictive cardiomyopathy. However, in this case it is most likely due to a marked decrease in left atrial compliance induced by the thick fibrous scar encasing the atrial.
一名35岁的白人女性患者出现放射性缩窄性心包炎。术中经食管超声心动图显示舒张期单一流向模式。在根治性心包切除术后，这种肺血流模式立即恢复为正常的收缩期/舒张期双相血流形态。这种异常血流模式以前被描述为限制型心肌病的典型表现。然而，在本例中，这很可能是由于包裹心房的厚纤维瘢痕导致左心房顺应性显著降低所致。
