title: Dynamic circle image in left ventricle outflow tract.
abstract: A 46-year-old man presented with a complaint of effort dyspnea. On transthoracic echocardiography a circle appeared in LVOT. It was seen freely floating, disappearing in every systole and appearing again in diastole. Turbulence was seen inside the circle with color Doppler. Transesophageal echocardiography showed aortic cusps and their coaptation to be normal. Aortic root diameters were normal at the annulus, sinus of Valsalva, and sinotubular junction. There were no signs of dissection, infective endocarditis or abscess. But as the probe was advanced, left sinus of Valsalva was found to be prolapsed, and ruptured into LVOT.
