Abstract
Transaxillary implantation of a temporary microaxial left ventricular assist device in patients suffering from cardiogenic shock is an established technique. We present a 77-year-old female patient with severe mitral regurgitation. She underwent minimally invasive surgical mitral valve replacement. After an uneventful postoperative course, the patient developed acute heart failure on the 11th postoperative day. Transthoracic echocardiography revealed new onset of takotsubo cardiomyopathy with a severely decreased left ventricular ejection fraction. Implantation of a microaxial flow pump for left ventricular decompression was scheduled. Preoperative computed tomography revealed a rectangular course of the right subclavian artery. To advance the Impella we employed an introducer fitted over the guidewire behind the Impella device as a 'cue stick' to move the rigid part of the pump forward to overcome the kinking using a 'shuffleboard technique'. The haemodynamic situation stabilized immediately after implantation. The Impella 5.5 was successfully weaned after six days of support. In the event of (rectangular) kinking of the subclavian artery, the 'shuffleboard technique' can be used for successful positioning of the pump.
