Abstract :Hypertrophic cardiomyopathy (HCM) is a common feline heart disease characterized by left ventricular hypertrophy. Mitral valve stenosis is an extremely rare heart disease in small animals that causes partial obstruction of blood flow from the left atrium (LA) to the left ventricle during diastole. An eight-month-old Scottish Fold cat was brought to Selcuk University Animal Hospital with a complaint of dyspnea. Physical examination revealed tachypnea, dyspnea, and a grade 3/6 systolic murmur. Transthoracic echocardiography showed increased left ventricular wall thickness and LA dilation. Two-dimensional echocardiography revealed incompletely separated mitral valve leaflets, a narrowed mitral valve orifice area, and marked diastolic turbulence at the mitral valve level on color Doppler. Spectral Doppler demonstrated a high mean pressure gradient across the mitral valve inflow. These findings suggest that mitral valve stenosis and hypertrophic cardiomyopathy can coexist in cats and that echocardiography is a valuable diagnostic and evaluative tool for this condition.
