Insights
Laser angioplasty for severe coronary artery disease led to dye extravasation and acute vessel occlusion. Subsequent percutaneous transluminal coronary angioplasty (PTCA) successfully resolved the complication, restoring blood flow and achieving a good outcome.
Area of Science:
- Interventional Cardiology
- Cardiovascular Imaging
- Vascular Interventions
Background:
- Recurrent angina pectoris at rest indicates significant coronary artery disease.
- Two-vessel disease with severe stenosis in the circumflex and left anterior descending arteries necessitates intervention.
Observation:
- Laser angioplasty was performed for subtotal and 90% stenoses.
- Dye extravasation occurred during laser ablation, leading to acute vessel occlusion.
Findings:
- Percutaneous transluminal coronary angioplasty (PTCA) was successfully performed after laser angioplasty complications.
- The PTCA resolved dye extravasation and vessel occlusion, yielding a satisfactory angiographic result.
- Echocardiography ruled out pericardial effusion; follow-up angiography confirmed the successful outcome.
Implications:
- This case highlights the potential complications of laser angioplasty in complex coronary lesions.
- Prompt and effective management with PTCA can salvage outcomes in such scenarios.
- Successful intervention allowed for early patient discharge and a normal exercise test, demonstrating the efficacy of combined approaches.
Abstract:
A 56-year-old patient with recurrent episodes of angina pectoris at rest was admitted for left-heart catheterization. The coronary angiogram revealed two-vessel disease with a subtotal stenosis in the circumflex artery and a long 90% stenosis in the proximal part of the left anterior descending artery. On the basis of symptoms and coronary morphology laser angioplasty was performed. After a total of 99 s of energy delivery extravasation of dye occurred at the site of ablation. Due to acute vessel occlusion subsequent PTCA was performed, resulting in a satisfactory angiographic result. Extravasation of dye was terminated after PTCA and was absent at short-term follow-up angiography. No signs of pericardial effusion were detectable by two-dimensional and M-mode echocardiography. A control angiogram disclosed the identical result the day after the acute intervention, and the patient could be discharged with a normal exercise test 1 week later.
