• Exposure
    • Perform a left anterolateral thoracotomy, extend across the sternum (clamshell) if more exposure needed
    • Open pericardium vertically anterior to phrenic nerve
    • Retract or incise further for exposure of injury site
  • Control of bleeding
    • Apply digital pressure or place a Foley catheter into the wound and inflate to control bleeding temporarily
    • Use skin stapler as a temporising measure on linear lacerations if suturing is delayed
  • Definitive repair
    • Use non-absorbable monofilament suture (e.g. 3-0 or 4-0 polypropylene) on a Pledgeted needle
    • Close linear wounds with interrupted horizontal mattress sutures with pledgets to prevent tearing through the myocardium
    • Avoid deep bites near coronary vessels — shallow, controlled suture placement
    • For small ventricular wounds: may use figure-of-eight or horizontal mattress
    • For right ventricle: take extra care due to thin wall and risk of tearing
    • For atrial wounds: delicate repair with finer suture and small pledgets
  • Adjuncts and closure
    • Ensure haemostasis before closing pericardium loosely or leaving it open if oedema is expected
    • Place pericardial or mediastinal drain if indicated
    • Close chest in standard layers if patient is stable
  • Post-op considerations
    • Monitor for arrhythmias, tamponade, or myocardial dysfunction
    • ICU care with inotropes if required
    • Serial echocardiography to assess repair integrity
