Common complications of mitral regurgitation surgery blood loss, systemic embolization, structural deterioration, left ventricular systolic dysfunction, endocarditis and other infections.

• Common complications of mitral regurgitation surgery including:^[1][2][3]

Risks for any surgery

• Blood clots in the legs that may travel to the lungs
• Blood loss
• Breathing problems
• Infection, including in the lungs, kidneys, bladder, chest, or heart valves

• Memory loss and loss of mental clarity, or “fuzzy thinking.”
• Post-pericardiotomy syndrome, which is a low-grade fever and chest pain. This could last for up to 6 months.

Prosthetic heart valves are associated with a variety of complications

• Structural deterioration, particularly with bioprosthetic valves
• Valve obstruction due to thrombosis or pannus formation
• Systemic embolization
• Bleeding
• Endocarditis and other infections
• Left ventricular systolic dysfunction, which may be preexisting.
• Hemolytic anemia
