Objectives: Ultrasonography is an essential examination performed in various clinical fields. The number of clinical sonographers has been increasing. However, the working environments and conditions at each facility are different, leading to diverse problems. Among them, the emerging issue is the sexual disagreement between the sonographer and patient at the time of echocardiography. Since the patient must expose their breast during echocardiography, female patients may refuse to undergo the examination when conducted by a male sonographer. This study aimed to conduct a questionnaire survey to understand the measures for sonographer-patient gender mismatch at different facilities., Methods: A questionnaire on the implementation of echocardiography by male sonographers for female patients was answered by representatives and specialist technicians of the Japanese Society of Echocardiography., Results: Questionnaire responses were obtained from 50 facilities (59 participants). A total of 70% of the facilities restricted male sonographers from conducting echocardiography examinations for female patients. Among them, 81% of the facilities serviced female patients aged 60 years or younger., Conclusions: It has become clear that the gender selection of echocardiographic examiners varies from facility to facility, and providing a sufficient explanation before echocardiographic examination is necessary to avoid causing uncomfortable situations for female patients., (© 2022.

Background: Exercise stress echocardiography has been used to assess myocardial reserve in various heart diseases. This study examined the ventricular myocardial response to exercise in Fontan patients using exercise stress echocardiography., Methods: Twenty-five Fontan patients and 19 control subjects underwent semi-supine bicycle exercise stress echocardiography in this prospective, single-center, cross-sectional study. Pulsed-wave Doppler tissue imaging peak systolic (s') and diastolic (e') velocities, longitudinal strain and systolic strain rate, and early diastolic strain rate data at rest and at peak exercise were obtained for the systemic ventricle. The myocardial reserve of functional parameters was calculated as the difference between peak exercise and rest., Results: Inter- and intra-observer reliability were both high for exercise stress echocardiography measurements. Compared with controls, Fontan patients had significantly lower s', e', longitudinal systolic strain and strain rate, and early diastolic longitudinal strain rate at rest and at peak exercise as well as reduced myocardial reserve., Conclusions: Fontan patients have markedly reduced myocardial reserve during exercise. The use of exercise stress echocardiography assessment may improve the clinical management of Fontan patients., (© 2021. Japanese Society of Echocardiography.)
