Two-dimensional echocardiography is the method of choice for imaging and diagnosis in patients with hypertrophic cardiomyopathy. However, ultrasound examination of the left ventricular apex by transthoracic echocardiography is often inadequate so that hypertrophy localised to this region may be missed. The purpose of this study was to evaluate the use of multiplane transoesophageal echocardiography in the diagnosis and assessment of apical hypertrophic cardiomyopathy. Six patients with apical hypertrophic cardiomyopathy underwent transthoracic and multiple transoesophageal echocardiography. Assessment of the proximal left ventricle was possible in all patients by both techniques and normal wall thickness measurements were obtained. Assessment of the distal left ventricle by multiple transesophageal echococardiography revealed hypertrophy of the apex (range 1.7-2.9 cm) and less marked hypertrophy of the distal segments of the left ventricle in all 6 patients (1.4-2.2 cm). Examination of the papillary muscles was also possible and hypertrophy was detected in 2 patients. By transthoracic echocardiography, hypertrophy was detected in the distal left ventricle of 5 patients and values w
