Key Points
- To describe an uncommon and life-threatening complication of coronary artery perforation during balloon angioplasty and detail its acute clinical management.
- Clinical assessment and procedural monitoring of a patient undergoing percutaneous transluminal coronary angioplasty.
- Diagnostic confirmation of vascular perforation using contrast dye extravasation and hemodynamic pressure readings.
- Emergency intervention protocol involving pericardiocentesis followed by surgical revascularization.
- Mechanical coronary artery perforation occurred due to the dilatation catheter, triggering immediate acute pericardial tamponade.
- Hemodynamic collapse was halted through immediate pericardiocentesis, stabilizing the patient for definitive, successful coronary artery bypass grafting.
- A sharp anatomical angle in the target vessel was considered the primary contributing anatomical factor for the perforation.
