Transthoracic two dimensional echocardiography is the mainstay of the echocardiography. Virtually all types of mitral, aortic, tricuspid and pulmonic valve disease and evaluation of prosthetic heart valves can be characterized anatomically using two-dimensional echocardiography. The echocardiographic hallmark of infective endocarditis is the formation of vegetation on a valvular surface. The anatomical impairment due to endocarditis and its complications can be detected with two-dimensional echocardiography. This technique evaluates all forms of congenital heart disease in adults and children. Detection of pericardial effusion was one of the earliest uses of echocardiography and it remains the predominant diagnostic tool for detection, quantitation and determination of the physiological significance and characteristics of pericardial effusion according to its reason. Three basic types of cardiomyopathies; dilated, hypertrophic and restrictive can be detected with two-dimensional echocardiography. The characteristic echocardiographic changes are; dilatation of left heart chambers and global systolic dysfunction for dilated cardiomyopathy, inappropriate and pathological hypertrophy of the left ventricle or interventricular septum and systolic anterior motion of the mitral valve for hypertrophic cardiomyopathy, dilated atria and preserved systolic function with stiff myocardium for restrictive cardiomyopathy. Coronary artery disease and myocardial infarction can be detected with two-dimensional echocardiography in a patient with chest pain and regional wall motion abnormality. Most of the complications of myocardial infarction such as; left ventricular thrombi, myocardial rupture and pericardial effusion can be detected, and ejection fraction of these patients can be calculated. Disease of proximal aorta, intracardiac thrombi and masses and left ventricular hypertrophy in hypertensive patients can be detected with two-dimensional echocardiography.Keywords: Cardiac imaging, two-dimensional echocardiographyTurkiye Klinikleri J Int Med Sci 2005, 1(42):26-36
