LVOT Obstruction
Pronunciation: EL-vot ob-STRUK-shun
Also written as: LVOT — Left Ventricular Outflow Tract
Left Ventricular Outflow Tract obstruction, a condition where blood flow from the left ventricle is impeded, often dynamic in elderly patients.
Full Definition
Left Ventricular Outflow Tract (LVOT) obstruction refers to impedance of blood flow from the left ventricle to the aorta, which can be fixed or dynamic. In geriatric cardiology, this condition often presents as hypertrophic obstructive cardiomyopathy or can develop secondary to age-related cardiac changes and medications. Dynamic LVOT obstruction can be precipitated by dehydration, vasodilation, or increased contractility. Symptoms include dyspnea, chest pain, and syncope, particularly with exertion. Management in elderly patients requires careful attention to volume status, medication effects, and functional limitations.
Usage
Usage note: LVOT is commonly used as an abbreviation; spell out on first use in patient documents.
