    Pericardiectomy can cause paradoxical septal motion in most patients, even with normal right ventricular dimensions. This study observed this specific septal motion change after the surgical procedure.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Echocardiography

    Background:

    • Interventricular septal motion is influenced by various cardiac conditions.
    • Pericardiectomy is a surgical procedure involving the removal of the pericardium.

    Purpose of the Study:

    • To evaluate the impact of pericardiectomy on interventricular septal motion.
    • To assess changes in septal motion following pericardiectomy.

    Main Methods:

    • Echocardiography was used to assess septal motion in 9 post-pericardiectomy patients.
    • Patients were evaluated between 1 week and 58 months after surgery.
    • Exclusion criteria included specific cardiac conditions like left bundle branch block and myocardial infarction.

    Main Results:

    Related Experiment Videos

    • Paradoxical septal motion was observed in 7 out of 9 patients post-pericardiectomy.
    • Septal motion was normal in 1 patient and unevaluable in another.
    • Preoperative normal septal motion changed to paradoxical in both patients with satisfactory preoperative echocardiograms.
    • Right ventricular internal dimension remained normal in the majority of patients.

    Conclusions:

    • Pericardiectomy is associated with a high incidence of paradoxical septal motion.
    • Unlike other causes of paradoxical septal motion, right ventricular dimensions typically remain normal after pericardiectomy.
