Clinical presentation
Several cases presenting dyspnea, fatigue and symptoms and signs due to obstructive Hypertrophic Cardiomyopathy have been described8,12; while our patient main complaint was lipothymia, these other symptoms were also present. Less frequently, asymptomatic cases have been reported, with clinical presentation being a new heart murmur identified during follow up 17,18. Although hypertrophic cardiomyopathy due to tacrolimus is the most frequent type of cardiomyopathy described, few cases of dilated cardiomyopathy have been also described 19,20.
