We present the rare case of a patient with pulmonary hypertension in the context of the stiff left atrial syndrome after extensive catheter ablation, a unique constellation characterized by high pulmonary artery and pulmonary artery wedge pressures due to left atrial dysfunction but normal left ventricular end-diastolic pressure, normal mitral valve, and absence pulmonary vein stenosis. This patient was surprisingly oligosymptomatic, however, which may have been due to a persistent post-puncture atrial septal defect, which may have allowed for controlled left atrial decompression, which is in line with the novel concept of the catheter-based creation of an intracardiac shunt as a treatment for heart failure.
我们报告了一例罕见病例，该患者在广泛导管消融术后出现左心房僵硬综合征相关肺动脉高压，其特征为左心房功能障碍导致肺动脉和肺动脉楔压升高，但左心室舒张末期压正常、二尖瓣正常且无肺静脉狭窄。然而，该患者症状出奇地少，这可能是由于持续性穿刺后房间隔缺损，这可能允许左心房减压得到控制，这与经导管创建心内分流作为心力衰竭治疗的新概念一致。
