In order to make a right diagnosis and to establish the indications for surgical treatment a standard algorithm of investigations was prepared: examination, collecting the detailed life history, establishing a type and a degree of deformation, chest and column radiological examination, ECG, spirography and heart ultrasound examination.', 'On basis of physical examination and anamnestic data the most clinical signs and complaints were established. The heart compression was found in preoperative X-rays in 476 (94.4%) patients, the heart was rotated and dislocated in 441 (87.5%) patients.
