One of the most important variables in assessing hemodynamic status in the intensive care unit (ICU) is the cardiac function and blood pressure. Invasive methods such as pulmonary artery catheter and arterial line allow monitoring of blood pressure and cardiac function accurately and reliably. However, their use is not without drawbacks, especially when the invasive nature of these procedures and complications associated with them are considered. There are several newer methods of noninvasive and minimally invasive hemodynamic monitoring available. In this manuscript, we will review these different methods of minimally invasive and non-invasive hemodynamic monitoring and will discuss their advantages, drawbacks and limitations.

Valve replacement in high-risk patients with severe aortic stenosis has undergone a huge paradigm shift in the recent years in terms of procedural details and vascular access site for patients who have poor peripheral access. Carotid artery is one of the more promising access sites which has been proven to provide a good alternative site with comparable outcomes to transfemoral approach. In this manuscript, we will provide a review of the current literature on transaortic, transapical, transaxillary and transcarotid approaches to transcatheter aortic valve replacement (TAVR) while focusing on the transcarotid approach.
