In patients with complex coronary lesions, percutaneous coronary intervention guided by intravascular imaging improved cardiovascular outcomes compared with percutaneous coronary intervention guided by angiography.

Hypertrophic cardiomyopathy (HCM) is defined by ventricular hypertrophy. However, the broader phenotype includes abnormal cardiomyocyte orientation (disarray), myocardial ischaemia and electrical abnormalities, which seem to manifest before overt hypertrophy. With advances in cascade genetic testing and novel therapeutic agents, the detection of subclinical HCM is a rapidly emerging priority. In this context, we outline the role of novel biomarkers, particularly quantitative perfusion and diffusion tensor MRI.

Researchers have engineered a wearable device that adheres to the skin and uses ultrasound imaging and a deep learning model to produce a dynamic, real-time assessment of cardiac function.
