Valvular reoperations have high mortality in emergencies, but acceptable rates in elective cases. Key risk factors include advanced age and emergency surgery.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Outcomes
  • Valvular Heart Disease Management

Background:

  • Valvular reoperations are complex procedures.
  • Understanding the risks associated with repeat valve surgery is crucial for patient management.

Purpose of the Study:

  • To determine the incidence of mortality and morbidity in patients undergoing valvular reoperations.
  • To identify independent risk factors associated with adverse outcomes in valvular reoperations.

Main Methods:

  • A retrospective analysis of 309 valvular reoperations performed between January 1993 and December 2003.
  • Data collected included reasons for reoperation, valve types, and surgical urgency (elective vs. emergency).

Main Results:

  • Overall hospital mortality was 14.23%, with significantly higher rates in emergency cases (35.5%) compared to elective (10.6%).
  • Independent risk factors for mortality included age > 60, emergency surgery, preoperative cerebrovascular accident, and concomitant ascending aorta replacement.
  • Morbidity included permanent pacemaker requirement (3.9%), cerebrovascular events (1%), and mediastinitis (0.3%).

Conclusions:

  • Valvular reoperations can be performed with acceptable outcomes in elective settings.
  • Mortality rates remain very high in emergent valvular reoperations, highlighting the need for careful patient selection and risk stratification.
