Mechanical Circulatory Support (MCS) refers to devices that assist or replace the heart's pumping function in patients with severe heart failure. These devices help maintain blood flow and oxygen delivery to vital organs, improving the patient's quality of life and potentially prolonging survival. Common types of MCS include ventricular assist devices (VADs) and total artificial hearts. MCS is often used as a temporary solution while patients await a heart transplant or as a long-term option for those who are not candidates for transplantation. The use of MCS requires careful monitoring and management by a specialized medical team to ensure optimal outcomes and minimize complications.
