Ventricular diverticula are a rare congenital cardiac disorder presenting with an extremely low incidence. The presence of an apical diverticulum of the right ventricle has been associated with other congenital heart diseases such as tetralogy of Fallot. An important defining characteristic of ventricular diverticula that separates them from aneurysms through imaging techniques, is that they possess myocardial contraction synchronous to the adjacent walls, contributing to the ventricular stroke volume, so they do not usually require surgical treatment.
A 15-year-old male, currently asymptomatic, in follow up due to a pulmonary valve prosthesis placement and a history of corrected tetralogy of Fallot at 18 months old, underwent a cardiac magnetic resonance imaging in February 2024. A diverticulum was detected in the apical inferolateral wall of the right ventricle, which was not documented in the cardiac magnetic resonance imaging prior to valve prosthesis placement.
Right ventricular diverticula are a rare entity. To this date we could not find another case of a pulmonary valve placement, followed by a right ventricular diverticulum appearance.
心室憩室是一种罕见的先天性心脏疾病，发病率极低。右心室心尖部憩室的存在与其他先天性心脏病如法洛四联症有关。通过成像技术将心室憩室与动脉瘤区分开来的一个重要特征是，它们具有与相邻心肌壁同步的收缩，有助于心室的每搏输出量，因此通常不需要手术治疗。
一名15岁男性，目前无症状，因曾接受肺动脉瓣置换术且18个月大时曾接受法洛四联症矫正手术而接受随访，于2024年2月接受了心脏磁共振成像检查。在右心室心尖下外侧壁发现一个憩室，在瓣膜置换术前的心脏磁共振成像中未记录到该憩室。
右心室憩室是一种罕见的病症。截至目前，我们尚未发现另一例肺动脉瓣置换术后出现右心室憩室的病例。
