Cardiac tamponade following percutaneous transluminal coronary angioplasty: four case reports
Insights
Cardiac tamponade after percutaneous transluminal coronary angioplasty (PTCA) may arise from minor right ventricular perforations. Impaired hemostasis, often due to anticoagulation, appears to be a key factor in this serious complication.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Percutaneous transluminal coronary angioplasty (PTCA) is associated with potential complications.
- These complications can include coronary artery dissection, spasm, rupture, and perforation.
Purpose of the Study:
- To describe cases of cardiac tamponade following PTCA.
- To investigate the presumed cause of cardiac tamponade as right ventricular (RV) perforation.
- To explore the role of impaired hemostasis in the development of tamponade.
Main Methods:
- Case series report of four patients experiencing cardiac tamponade post-PTCA.
- Review of patient histories, including anticoagulation and antiplatelet therapy.
- Analysis of clinical presentation and outcomes following operative intervention.
Main Results:
- Four patients developed cardiac tamponade, presumed secondary to RV perforation after PTCA.
- All patients received significant heparin doses, and three received antiplatelet therapy.
- Cardiac tamponade occurred hours after PTCA in three patients; all recovered well after intervention without requiring perforation repair.
Conclusions:
- Minor right ventricular perforations, when combined with impaired hemostasis (e.g., from anticoagulation), can lead to cardiac tamponade.
- Prompt operative intervention is effective in managing this complication.
- Strategies for standby pacing in such cases warrant consideration.
Abstract:
Percutaneous transluminal coronary angioplasty (PTCA) has had complications related to dilating catheters and guide wires such as coronary artery dissection, spasm, rupture, and perforation. This report describes four patients who developed cardiac tamponade following PTCA, presumably from right ventricular (RV) perforation. All four received large doses of heparin during PTCA and three received antiplatelet therapy. In three cases, cardiac tamponade occurred several hours after PTCA. All patients did well following operative intervention and no patient required repair of a cardiac perforation. We postulate that impaired hemostasis in the presence of an otherwise inconsequential RV perforation causes tamponade. Three alternatives to provide standby pacing are proposed.
