Chronic pericarditis can take the form of localised annular bands constricting the atrioventricular grooves, the pulmonary infundibulum and, rarely, the atria. The authors report two cases of pericardial bands surrounding the ventricles and involving the atrioventricular groove resulting in a biloculation of the left ventricle. One case was complicated by adiastole and one by mitral regurgitation due to involvement of the posterior mitral leaflet. Magnetic resonance imaging gave precise definition of these bands and of their extension into the myocardium. This investigation was a valuable complement before surgery of the localised constriction.
慢性心包炎可表现为局部环形带，压迫房室沟、肺动脉圆锥，罕见情况下压迫心房。作者报告了两例心包带环绕心室并累及房室沟，导致左心室分成两腔的病例。其中一例并发舒张功能障碍，另一例因二尖瓣后叶受累出现二尖瓣反流。磁共振成像精确显示了这些带及其向心肌的延伸。这项检查是局部缩窄手术前的一项重要补充。
