Transcatheter structural heart intervention (TSHI) has gained popularity over the past decade as a means of cardiac intervention in patients with prohibitive surgical risks. Following the exponential rise in cases and devices developed over the period, there has been increased focus on developing the role of “structural imagers” amongst cardiologists. This review, as part of a growing initiative to develop the field of interventional echocardiography, aims to highlight the role of echocardiography in myriad TSHIs available within Asia. We first discuss the various echocardiography-based imaging modalities, including 3-dimensional echocardiography, fusion imaging, and intracardiac echocardiography. We then highlight a selected list of structural interventions available in the region—a combination of established interventions alongside novel approaches—describing key anatomic and pathologic characteristics related to the relevant structural heart diseases, before delving into various aspects of echocardiography imaging for each TSHI. • Transcatheter structural heart intervention services have seen an exponential rise across the Asia-Pacific region. • The need for growing expertise in interventional echocardiography complements the rise in such interventions. • Developing interventional echocardiography requires a structured curriculum, accessibility to novel echocardiographic modalities and regional networking.
