• The average mortality risk associated with mitral valve repair is less than 1%, reflecting its safety. However, there are some risks and considerations to keep in mind.

• For patients who smoke, it is crucial to quit smoking at least 2 to 4 weeks before surgery. Quitting too close to the procedure can lead to short-term bronchorrhea (excess secretion in the airways), which may cause persistent coughing and complicate recovery.

• Stopping smoking beforehand helps reduce complications and improve overall recovery outcomes.

Despite the low risk of mortality, potential complications include:

• Blood Clots: Blood clots can form in the legs, and if they dislodge, they may travel to the lungs, causing pulmonary embolism.

• Blood Loss: Blood loss during surgery may require transfusions.

• Breathing Problems: Breathing difficulties may arise from anesthesia or complications that affect lung function.

• Infections: Infections can occur in various areas, such as the lungs, kidneys, bladder, chest, or heart valves.

• Medication Reactions: Some patients may experience adverse reactions to medications,
  including allergic responses or negative drug interactions.
