Hypertrophic Cardiomyopathy (HCM) is a rather common condition seen by anesthesiologists in the perioperative phase. HCM was thought to be a rare condition fifty years ago. However, our understanding and capacity to diagnose HCM patients has vastly increased in recent years. Patients with HCM have a wide range of genotypic and phenotypic characteristics. A subset of these patients does, in fact, have the HCM genotype but not the manifestation (left ventricular hypertrophy). Pharmacotherapy to control symptoms, implantable cardiac defibrillators to manage malignant arrhythmias, and surgical myectomy and septal ablation to reduce the left ventricular outflow obstruction are all options for these individuals. For the perioperative care of these patients, an accurate diagnosis is critical. Left ventricular hypertrophy, left ventricular outflow tract gradients, systolic and diastolic function, and mitral valve morphology and function are typically used to make the diagnosis. Cardiac magnetic resonance imaging can also be used for diagnosis.
