• Dislodgement of valvular vegetations
• Rupture of chordae tendineae
• Calcification of the valve leaflets
• Erosion of the valve cusps

  The correct answer is: Dislodgement of valvular vegetations. Explanation: In infective endocarditis, the primary cause of embolic complications is the dislodgement of valvular vegetations. These vegetations are masses of thrombus and microorganisms (such as bacteria) that form on the heart valves during infection. When these vegetations break off from the valve, they can travel through the bloodstream and lodge in various organs, causing embolic events.

• Rupture of chordae tendineae: This may lead to valve dysfunction and regurgitation, but it is not typically the cause of embolic events.
• Calcification of the valve leaflets: This is associated with chronic valve disease (such as calcific aortic stenosis), but it does not directly lead to embolic complications in infective endocarditis.
• Erosion of the valve cusps: Erosion can occur in severe infective endocarditis, but it is the vegetations themselves that pose the greatest risk for embolism, not the erosion itself.

Thus, dislodgement of valvular vegetations is the primary mechanism responsible for embolic complications in infective endocarditis.
