Time to move to the right--the study of right ventricular systolic performance: too long neglected

Although the evidence that right ventricular (RV) function has significant impact on cardiac hemodynamics and outcome is indisputable, its evaluation has been hampered by problems with image quality, geometric variability, and the absence of a standard of reference. A resurgence of research activity has sought to discern the pathophysiology of RV dysfunction and to explore new methods for measuring performance. Noninvasive techniques such as tissue Doppler echocardiography, three-dimensional echocardiography, and magnetic resonance imaging provide new quantitative information and may improve prediction of outcomes. These advances in technology, and the recognition that RV systolic function is essential in many conditions, provide the impetus for future studies. This review highlights the past and present efforts to incorporate RV systolic function into the mainstream of cardiology practice.
