Summary
This case study details the successful surgical repair of a rare posterior ventricular septal perforation (VSP) following a heart attack. The innovative right ventricular incision approach offers a viable option for complex VSP cases.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Ventricular septal perforation (VSP) is a severe complication of myocardial infarction.
- Posterior VSP carries a poorer prognosis compared to other locations.
Observation:
- A 79-year-old male presented with posterior VSP after acute postero-inferior myocardial infarction.
- Ultrasound Cardiography confirmed VSP and right ventricle inferior wall akinesis.
- The patient remained hemodynamically stable without intraaortic balloon pumping support.
Findings:
- Successful surgical repair of posterior VSP was achieved using an inferior right ventricular incision.
- The "sandwich patch" technique with BioGlue reinforcement was employed.
- No residual shunt was detected postoperatively.
Implications:
- The inferior right ventricular incision approach is a valuable technique for posterior VSP repair, especially with extensive necrosis.
- This case highlights a successful management strategy for a life-threatening post-infarction complication.
