Heart failure with preserved left ventricular ejection fraction. Revision of exceptional case of valvular and subvalvular aortic obstruction

Subvalvular stenosis represents the second most common cause of aortic stenosis. However, it remains a rare disease. Its importance relays in a possible development of heart failure at an early age and the association with multiple cardiac defects. Surgical treatment is definitive resolution. In this case report, we describe a 28 years old man who begins with progressive dyspnea and palpitations since he was 17 years old. Later, the patients required a double valvular replacement due to a complex valvular and subvalvular aortic lesion that was diagnosed by echocardiography and cardiac magnetic resonance. Echocardiography and cardiac magnetic resonance are the diagnostic standard for this particular condition since these techniques allow characterizing the lesion and its hemodynamic repercussion in cardiac cavities and establishing the treatment. *Correspondence to: Nilda Espinola-Zavaleta, MD, PhD, Department of Nuclear Cardiology, Juan Badiano No 1, Colonia Sección XVI, PC 14080, Tlalpan, Mexico City, Mexico, E-mail: niesza2001@hotmail.com
