Hypertrophic cardiomyopathy encompasses a broad spectrum of muscular diseases that involve not only the interventricular septum and the left ventricular outflow tract but also the papillary muscles and the mitral valve apparatus. This article presents the successful surgical treatment of two patients with generalized hypertrophic cardiomyopathy with hypertrophy of the papillary muscles without severe septal hypertrophy: one with a history of unsuccessful chemical ablation and coronary disease following an interventional event, and another young patient without a history of chronic degenerative diseases who developed hypertrophic cardiomyopathy during her third pregnancy. Both patients with left ventricular outflow tract gradients greater than 55 mmHg and those who underwent surgical treatment had a gradient of less than 10 mmHg.Hypertrophic cardiomyopathy encompasses a broad spectrum of muscular diseases that involve not only the interventricular septum and the left ventricular outflow tract but also the papillary muscles and the mitral valve apparatus.
