A 2. 5～5. 5 MHz transducer was used according to the acoustic depth of the heart examined. 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.
