William Ganz

Biography

• Born on January 7, 1919 in Košice, Czechoslovakia
• 1937 – Began medical studies at Charles University, Prague. 1938 Munich agreement made Kosice part of Hungary and Vilem was made a foreigner in Prague and had to return to his hometown, renamed Kassa at the time. He was drafted into Hungarian forced-labor camp
• 1944 – Escaped Nazi persecution at Auschwitz by using false documents to travel to Budapest where he met his wife Magda
• 1947 – Graduated at the top of his class, completing his medical studies at Charles University, Prague. Here Vilem worked with Arnost Fronek to engineer vascular catheters and pioneered the thermodilution method for measuring blood flow⁵
• 1966 – Migrated to Los Angeles, United States of America. Worked with Jeremy Swan and Edwards Laboratory to develop the Swan-Ganz catheter
• 1970 – Swan and Ganz publish report Catheterization of the heart in man with use of a flow-directed balloon-tipped catheter.
• Died on November 11, 2009

Medical Eponyms

Swan-Ganz catheter – pulmonary artery catheter (1970)

Pictured below is the “extruded polyvinyl-chloride catheter 1.7mm in outer diameter” with the balloon tipped catheter and “attached to a strain-gauge catheter.” The pulmonary artery was accessed via “antecubital-vein cutdown” during the inception

Controversies

He claimed that the “sail-boat” idea was apocryphal and that the use of the balloon was driven by both the need to float the catheter and, most important, to cover the sharp tip of the catheter to reduce the mechanical irritation to the endocardium that caused arrhythmia during passage.⁶
