Key result
Asymptomatic man develops progressive LV apical hypertrophy four years after orthotopic heart transplantation.
Why the study?
Apical hypertrophic cardiomyopathy is a relatively rare phenotype characterized by focal left ventricular apical thickening, and its emergence following orthotopic heart transplantation warrants analysis of etiology, clinical manifestations, and prognosis.

Should not yet change post-transplant surveillance; leaves open apical hypertrophy as a rare late sequela.
Apical hypertrophic cardiomyopathy (AHCM) is a relatively rare phenotype of hypertrophic cardiomyopathy, which is characterized by focal thickening of the left ventricular (LV) apical myocardium, showing a spade-shaped shadow on the left ventricle. We present the case of a 59-year-old man who was found to have AHCM, is an asymptomatic orthotopic heart transplantation (HTx) patient. This rare and progressive case of LV apical hypertrophy emerged from the fourth year post surgery. We analyzed the etiology of this case and summarized the clinical manifestations and prognosis of AHCM following HTx by reviewing our case and the literature.

Zhou et al. (2023) conducted a case report in Apical hypertrophic cardiomyopathy (AHCM) post heart transplantation (n=1). A 59-year-old asymptomatic man developed progressive left ventricular apical hypertrophy four years after undergoing orthotopic heart transplantation.
