[Supporting the pumpfunction of the right atrium. A new therapeutic concept after physiological repair of tricuspid atresia (author's transl)].

A new indication for the External Conterpulsation (ECP) is demonstrated. Due to the venous augmentation a "pulse wave" is created in the V. cava inferior and in the right atrium and the ECP acts as a "peripheral pumpventricle", thus increasing pulmonary blood flow and left ventricular enddiastolic pressure. This new application of ECP is of valve in cases with low output syndrome after physiological repair of tricuspid atresia as demonstreated in a case report.
