Group B was used x-ray fluoroscopy (a Philip mono-rotatable C arm X-ray equipment) as image guide with routine method reported by american college of cardiology cardiovascular technology assessment committee. TTE guiding CSC in site: The guide wire was inserted into left subclavicular vein and inferior vena cava and it was displayed clearly by TTE. The sheath could be displayed clearly too by TTE. CSC was put through the sheath into right atrium in prone position and was thoroughly showed by TTE via untypical parasternal four-chamber view.
