Levosimendan is a medication that helps improve heart function. It works by making the heart muscle contract more strongly and helps blood vessels relax. This medication is given before heart surgery to help prevent complications related to poor heart function, particularly in patients who have problems with their tricuspid valve (one of the heart valves). It’s especially useful for patients whose right side of the heart isn’t working as well as it should.

Tricuspid Regurgitation – A heart valve condition where the tricuspid valve doesn’t close properly, causing blood to flow backward into the right atrium when the right ventricle contracts. The condition can range from mild to severe, with moderate to severe cases causing the heart to work harder to pump blood effectively. The condition may develop gradually over time and can be related to other heart problems. When functional in nature, it occurs due to enlargement of the right ventricle or right atrium, rather than from direct valve damage. The condition can lead to fluid retention and decreased cardiac output.

Low Cardiac Output Syndrome – A condition where the heart cannot pump enough blood to meet the body’s needs. It is characterized by reduced blood flow from the heart, which can affect multiple organ systems. The condition can develop after heart surgery or in patients with severe heart conditions. The syndrome often requires supportive measures to maintain adequate circulation. It may be accompanied by symptoms such as fatigue, weakness, and decreased urine output.
