Dicrotic pulse after open heart surgery

R C Orchard, E Craige

    Circulation
    |November 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    A dicrotic pulse (DP) after valve replacement surgery is a significant indicator of poor prognosis. This postoperative finding, primarily in patients with regurgitant lesions, correlates with persistent left ventricular dysfunction and adverse clinical outcomes.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Echocardiography

    Background:

    • Valve replacement surgery is a common procedure for valvular heart disease.
    • Assessing postoperative complications and patient outcomes is crucial for surgical success.
    • The significance of a dicrotic pulse (DP) post-valve replacement requires further investigation.

    Purpose of the Study:

    • To determine the frequency and clinical significance of a dicrotic pulse (DP) after valve replacement surgery.
    • To identify patient characteristics and echocardiographic findings associated with postoperative DP.
    • To evaluate the prognostic value of DP in patients undergoing valve replacement.

    Main Methods:

    • Review of preoperative hemodynamic data and postoperative echophonocardiograms (EPCGs) in 108 patients.

    Related Experiment Videos

  • Comparison of dicrotic and nondicrotic groups based on preoperative and postoperative echocardiographic and hemodynamic parameters.
  • Analysis of the correlation between persistent DP and left ventricular function and clinical course.

    • Main Results:

    • A dicrotic pulse (DP) occurred predominantly in patients with aortic or mitral regurgitation undergoing valve replacement.
    • Preoperatively, patients who developed DP had significantly larger ventricular volumes and lower ejection fractions.
    • Postoperatively, the DP group exhibited impaired left ventricular dimensions and reduced posterior wall thickening, correlating with poor clinical outcomes.

    Conclusions:

    • A postoperative dicrotic pulse (DP) is a significant prognostic indicator following valve replacement.
    • The presence of DP suggests persistent left ventricular dysfunction and is associated with an adverse clinical course.
    • Echophonocardiography is valuable in identifying DP and assessing its prognostic implications after valve surgery.
