Left main and multivessel disease

Latest left main and multivessel disease content in interventional cardiology - research, practice, and education

The left main coronary artery provides the primary source of blood flow to the left ventricle. Diseases affecting the left main, by itself or in combination with multivessel disease, place the patient at significant risk for life-threatening cardiovascular events. Treatment requires an understanding of all available tools, devices and techniques, like those employed in invasive imaging and functional assessment, as well as taking into account underlying comorbidities such as diabetes. Advances in imaging techniques, as well as the use of adjunctive pharmacotherapy, vascular access or invasive interventions such as bypass surgery, are important, as are understanding bleeding risks.

Feasibility of sheathless Impella for protected percutaneous coronary intervention: a single-center experience

02 May 2025

Impella CP microaxial flow pump supports complete revascularisation during high-risk PCI, but standard implantation often leads to vascular complications. This article explores an initial experience with a sheathless implantation technique, which shows promise as a feasible and safe alternative.
