Feasibility, diagnostic performance and clinical value of an abbreviated echocardiography protocol in an out-patient cardiovascular setting: a pilot study.

Background: There has been a growing demand for echocardiography services over the last 5 years, with this supply-demand mismatch exacerbated by the COVID-19 pandemic. Prior studies have suggested a high proportion of normal findings among echocardiograms requested for patients without known cardiovascular disease, particularly in low-risk cohorts. This pilot study investigates the role of an abbreviated echocardiography protocol in improving access to echocardiography services in a low-risk outpatient setting within the rapid access chest pain (RACP) clinic.

Longitudinal changes of right ventricular deformation mechanics during trastuzumab therapy in breast cancer patients.

Background: Trastuzumab improves dramatically the prognosis of HER2-positive breast cancer patients, but it may lead to cardiotoxicity with left ventricular (LV) systolic dysfunction. Its effects on right ventricular (RV) function have not however been elucidated. We sought to assess LV and RV deformation mechanics during treatment with trastuzumab in breast cancer patients.
