Cardiac ECHO


In ultrasonocardiography (cardiac ECHO) examination, we can obtain various information on the structure and function of the heart from the body surface. The greatest advantages of this examinations are that it is a “non-invasive” examination which causes no pain or discomfort to the subject and is not associated with any risk of complications, and also that the results could be obtained immediately. A large volume of information can be obtained, and it is therefore an assessment that is indispensable for the diagnosis and treatment of heart diseases. The needs for cardiac ECHO are increasing year by year. In our hospital, we conduct around 7,000-8,000 cardiac ECHO examinations a year. We are constantly striving to maintain and improve not only the number but also the quality. As the experience and knowledge of the examiners greatly affect the quality of the evaluations, laboratory technicians and physicians who carry out this examination are constantly aware of learning and training opportunities.

Accompanying the opening of the Heart Center, several new machines equipped with the latest functions have been installed, and we are putting efforts into introducing new assessment methods using the latest technology. All the cardiac ECHO examinations of the hospital are done at the Heart Center. Using five latest machines, we have conducted 8,000 examinations during the last year. Another merit of cardiac ECHO is that the examination can be repeated noninvasively. With the increase in assessable parameters, cardiac ECHO has advanced to become an even more useful examination.

Regarding the assessment of cardiac functions, dilatation capability and poor coordination can be assessed using tissue Doppler technique and strain rate technique. These techniques are especially useful for preoperative evaluation of biventricular pacing (cardiac resynchronization therapy; CRT) for intractable heart failure. There is an increase in referrals from other hospitals for the purpose of evaluating indication for CRT. We are actively receiving requests for detailed evaluation of echocardiograms, stress echocardiography, transesophageal echocardiography, and cardiac dyssynchrony evaluation (for assessing indication of biventricular pacing), and would welcome referrals. All members of staff are doing our best aiming at precise and higher level echocardiographic studies (Mari Nishizaka, MD, PhD, Chief in Echo Lab)

Tissue Synchronization Imaging

The delay in wall motion (dyssynchrony) is assessed by measuring the time when contraction starts in different regions with reference to the time of beginning of aortic valve opening.
