Restrictive cardiomyopathy is one of the rarest forms of cardiomyopathies in paediatric patients characterised by impaired myocardial relaxation or compliance with restricted ventricular filling, leading to a reduced diastolic volume with a preserved systolic function. We report 2 cases-a 5-year-old boy who presented with abdominal distension and palpitation with family history of similar complaints but no definite genetic diagnosis as yet and a 5-year-old girl who presented with chronic cough and shortness of breath. Both cases were diagnosed in a tertiary care hospital in Muscat, Oman, in 2019 and are managed supportively with regular outpatient follow-up. This is the first series of reported cases of paediatric restrictive cardiomyopathy from Oman.
限制型心肌病是儿科患者中最罕见的心肌病形式之一，其特征为心肌松弛或顺应性受损，心室充盈受限，导致舒张期容积减少而收缩功能保持。我们报告了 2 例病例，一例为 5 岁男孩，表现为腹胀和心悸，有类似症状的家族史，但尚未明确遗传诊断，另一例为 5 岁女孩，表现为慢性咳嗽和呼吸急促。这两例病例均于 2019 年在阿曼的一家三级医疗机构确诊，目前采用支持性治疗并定期进行门诊随访。这是来自阿曼的首例儿科限制型心肌病系列报告。
