Endoventriculoplasty may worsen diastolic function, leading to a restrictive filling pattern in 8% of patients. This pattern predicts poor outcomes and necessitates caution in severely ill patients, particularly those with recent myocardial infarction.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Medical Imaging

Background:

  • Endoventriculoplasty with pericardial patch is used for anteroseptal ventricular aneurysm repair.
  • Limited data exists on its impact on diastolic left ventricular function.

Purpose of the Study:

  • To evaluate changes in diastolic left ventricular function after endoventriculoplasty.
  • To assess the influence of pulsed Doppler transmitral flow patterns on patient outcomes.

Main Methods:

  • Pulsed Doppler echocardiography was used to record diastolic transmitral flow.
  • Spectral analysis identified normal, inverted, and restrictive filling patterns.
  • Clinical and hemodynamic parameters were correlated with Doppler findings.

Main Results:

  • A significant minority (8%) developed a postoperative restrictive diastolic filling pattern.
  • These patients exhibited severe clinical and hemodynamic impairment.
  • Postoperative restrictive filling predicted 3-month mortality and treatment challenges.

Conclusions:

  • Endoventriculoplasty can adversely affect diastolic function, resulting in a restrictive pattern.
  • This pattern is associated with poor prognosis and difficult medical management.
  • Caution is advised for endoventriculoplasty in severely ill patients, especially post-myocardial infarction; consider conservative volume reduction.
