Revelation of an obstructive hypertrophic cardiomyopathy in an elderly patient.
Hypertrophic cardiomyopathy (HCM) is classified as a primary cardiomyopathy. HCM is a clinically heterogeneous but relatively common autosomal dominant genetic heart disease that probably is the most frequently occurring cardiomyopathy. HCM is characterized morphologically and defined by a hypertrophied, nondilated left ventriculum (LV) in the absence of another systemic or cardiac disease that is capable of producing the magnitude of wall thickening evident (e.g., systemic hypertension, aortic valve stenosis). Most HCM patients have the propensity to develop dynamic obstruction to LV outflow under resting or physiologically provocable conditions, produced by systolic anterior motion of the mitral valve with ventricular septal contact. The phenotypic features of HCM may develop at any age from infancy to adulthood, and are characterized by a great heterogeneity in the extent, magnitude, and distribution of left ventricular hypertrophy. Hypertrophic obstructive cardiomyopathy (HOCM) often leads to heart failure, severe ischemia, severe symptoms and death. Determination of the exact site of the hypertrophy and of the obstruction of the left ventricular outflow tract, in asymmetric septal hypertrophy, establishes which is the best treatment strategy. In the treatment of HOCM, drug therapy with negatively inotropic drugs, percutaneous transluminal septal myocardial ablation by alcohol-induced septal branch occlusion, surgical myectomy and DDD pacemaker therapy are considered the therapeutical options. We present a case of an obstructive hypertrophic cardiomyopathy in an 84-year-old Italian woman with a left ventricular outflow tract (LVOT) peak gradient with the Valsalva maneuver of 188 mm Hg and with a history of first episode of syncope.
