Abstract
Background: Critically ill patients undergoing bypass surgery experience a higher mortality and morbidity.
Hypothesis: The study was undertaken to evaluate the efficacy and value of percutaneous transluminal coronary angioplasty (PTCA) as a bridge to coronary artery bypass graft surgery (CABG) in high‐risk patients with refractory unstable angina or cardiogenic shock.
Methods: We present 11 seriously unstable patients with severe multivessel coronary artery disease undergoing culprit vessel PTCA. Angioplasty was performed not as a definitive procedure but rather as a bridge to surgical revascularization. All the patients had sustained at least one myocardial infarction prior to catheterization, all had refractory unstable angina, eight patients had only a single patent coronary artery, and five patients were in cardiogenic shock.
Results: Following PTCA, all patients enjoyed a stable in‐hospital period. One patient died 12 weeks after successful PTCA while awaiting second CABG. Seven patients subsequently underwent CABG and are doing well. The remaining three patients were also advised to undergo CABG, but elected to continue medical management.
Conclusions: Coronary angioplasty of the culprit vessel may play a role as a bridge to surgery in critically ill patients.
Keywords: refractory unstable angina, cardiogenic shock, culprit vessel angioplasty, interim/bridge procedure, coronary artery bypass surgery
