	'''Ventricular outflow tract obstruction''' (VOTO) is a condition characterized by a blockage or narrowing in the pathways through which blood exits the ventricles of the heart. This obstruction can occur in either the left or right ventricular outflow tract, leading to various clinical manifestations depending on the severity and location of the obstruction.
