Determination of the anatomical location of the ventricular septal defect (VSD), one of the complications that may develop after acute myocardial infarction (MI), affects the surgical intervention and surgical success. Improved surgical techniques and heart protection methods, increased anesthesia and reanimation experience with new prosthetic patches have increased the success of surgical intervention in post-MI VSD. Long-term survivals of patients treated surgically have been reported to be better than those who did not undergo surgery.
In autopsy studies, the incidence of VSD after acute myocardial infarction is 1-2%. According to epidemiological studies, post-MI VSD occurs more frequently in male patients 65 years of age and older who have a single-vessel disease and who have had an infarction for the first time. Post-MI VSD, which develops because of anterior MI, which constitutes 60% of myocardial infarctions, is the most common anteroapical septum, and VSDs, which are formed because of inferior MI (20-40%), are usually located in the posterior septum.
In this study, we investigated the risk factors affecting hospital mortality retrospectively in patients who developed post-MI VSD and operated.
