Urgent operation for acquired ventricular septal defect

C S Thomas, W C Alford, G R Burrus

    Annals of Surgery
    |June 1, 1982
    PubMed
    Summary

    Urgent surgery for ventricular septal defect (VSD) after heart attack is recommended. Early repair using patch techniques significantly improves survival rates compared to delayed interventions for postinfarction VSD.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Cardiovascular Research

    Background:

    • Ventricular septal defect (VSD) following myocardial infarction (MI) presents a critical surgical challenge.
    • Historically, delayed surgical repair was considered to allow for tissue stabilization, but recent outcomes suggest otherwise.

    Purpose of the Study:

    • To evaluate the efficacy of early surgical intervention versus conservative management for acute postinfarction VSD.
    • To determine if delaying repair offers technical advantages or improves survival in patients with acquired VSD.

    Main Methods:

    • Retrospective review of 22 patients with acute VSD (within four weeks of murmur onset) treated since 1970.
    • Analysis of outcomes based on timing of surgical intervention (early vs. delayed) and management strategies.

    Main Results:

    • Ten of 15 patients (67%) operated on within the first four weeks survived, with a potential for only one death using current techniques.
    • Five patients died during conservative medical therapy; two survived longer than four weeks without operation, one requiring delayed surgery.
    • Four of five surgical deaths were attributed to technical issues related to not using patch septal replacement, now considered essential.

    Conclusions:

    • An aggressive surgical approach is warranted for unstable patients with postinfarction VSD.
    • Early surgical repair, utilizing specific techniques like prosthetic patch septal replacement, yields superior survival rates.
    • Protracted medical therapy for postinfarction VSD is associated with higher mortality and offers no apparent technical advantages over early intervention.
