Plain-language summary
Mucopolysaccharidoses (MPS) are multisystemic diseases with significant clinical overlap between their types, with cardiac problems being among the most commonly observed manifestations and are also among the main causes of mortality in these patients. For some of the cardiovascular manifestations, such as aortic root dilation and valve diseases, there is no effective treatment currently available. Losartan, on the other hand, has been shown to be an effective drug for dilation of the aortic root, at least in animal models. This study aims to evaluate the safety and efficacy of losartan in patients with MPS VI and other mucopolysaccharidoses.
