ABSTRACT

Left outflow obstructions are fixed or dynamic, they are presented with or without ventricular septal defect. The fixed subaortic types are fibrous diafragms, fibromuscular tunnels, accessory mitral valve tissue, septal anomalous insertions of the chordae tendinae of the mitral, posterior displacement of the infundibular septum, hypertrophied anteroseptal muscle of the left ventricle and the supraortic stenotic forms of hour glass, diaphragmatic and diffused. The dynamic obstruction is the hypertrophic cardiomyopathy with or without left asymmetric ventricular septum. Obstructions are presented as isolated, combined or in association with another congenital heart disease; they produced left ventricular hypertrophy and malfunction of the mitral valve when it is involved. The knowledge of morphologic details in each obstructive type is the basement to interpret accurately the diagnostic imagenology and sustent the clinical judgment.
