The purpose of this report is to present clinicopathological features of two cases of hypertrophic cardiomyopathy (HCM) that underwent orthotopic heart transplantation (OHT) because of an unusually complex clinical course. One case is that of a 37-year-old man with HCM who underwent OHT because of a combination of recurrent severe ventricular arrhythmias and progressive heart failure that were refractory to medical treatment. The second case is that of a 43-year-old woman who underwent OHT because of progressive heart failure following 2 myectomy procedures. Both patients have had an uneventful post-OHT course. These cases highlight the variable spectrum of disease progression of HCM and the clinical challenges in the management of these patients.
