Stages of sequential wire shifting (SWS) technique. A - heavily dilated pulmonary vascular bed, B - distortion of Edward Lifesciences Swan-Ganz (S-G) catheter, irritation of right atrium (velvet arrow) caused atrial flutter with subsequent clinical decompensation, C - diagnostic EMERALD, Cordis, USA, guidewire 0.035 x 150 cm, 3 mm J tip wire is inserted into the left pulmonary artery (velvet arrow), D - multi-purpose (MPA), Cordis diagnostic catheter (velvet arrow) is introduced with the subsequent removal of the diagnostic wire E - 300 cm J-tip Whisper ES, Abbott, USA, angioplasty wire (velvet arrow) is placed via MPA catheter with subsequent introduction of Swan-Ganz (S-G) catheter (red arrow), F - angioplasty wire is used as a rail for the uneventful introduction of the S-G Edward Lifesciences catheter (velvet arrow), G - inflated balloon (velvet arrow) on the tip of the S-G Edward Lifesciences catheter enables acquisition of the adequate pulmonary wedge pressure (PWP). PT - pulmonary trunk, R/LPA - right/left pulmonary artery.
