Insights
Hybrid coronary revascularization (HCR) is a safe alternative to coronary artery bypass grafting (CABG), offering reduced blood transfusions and shorter hospital stays. However, HCR incurs higher hospital costs compared to traditional CABG.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Health Economics
Background:
- Hybrid coronary revascularization (HCR) integrates minimally invasive grafting with percutaneous coronary intervention for coronary artery disease.
- HCR presents a viable alternative to traditional surgical approaches.
Purpose of the Study:
- To compare the clinical outcomes and hospital costs of HCR versus conventional coronary artery bypass grafting (CABG).
Main Methods:
- Systematic literature searches were conducted using terms like "hybrid revascularization" and "coronary artery bypass grafting."
- A meta-analysis evaluated outcomes including blood transfusion, hospital costs, ventilation time, hospital stay, and major adverse events.
Main Results:
- HCR demonstrated significantly lower rates of blood transfusion (OR 0.38), shorter hospital stays (MD -1.48 days), and reduced ventilation time (MD -8.99 hours).
- Conversely, HCR was associated with significantly higher hospital costs (MD $3970).
- No significant differences were observed in other clinical outcomes.
Conclusions:
- Short-term HCR is clinically comparable to CABG in safety.
- HCR offers benefits like reduced blood transfusion needs and shorter hospital stays.
- The primary drawback of HCR is its increased hospital cost compared to CABG.
Background:
Hybrid coronary revascularization (HCR) combining minimally invasive grafting of the left internal mammary artery to the left anterior descending artery with percutaneous coronary intervention has become a viable option for treating coronary artery disease. The aim of this meta-analysis was to compare HCR with conventional coronary artery bypass grafting (CABG) in a range of clinical outcomes and hospital costs.
Methods:
To identify potential studies, systematic searches were carried out in various databases. The key search terms included "hybrid revascularization" AND "coronary artery bypass grafting" OR "HCR" OR "CABG." This was followed by a meta-analysis investigating the need for blood transfusion, hospital costs, ventilation time, hospital stay, cerebrovascular accident, myocardial infarction, mortality, postoperative atrial fibrillation, renal failure, operation duration, and ICU stay.
Results:
The requirement for blood transfusion was significantly lower for HCR: odds ratio 0.38 (95% confidence intervals [CIs] 0.31-0.46, P < .00001) as was the hospital stay: mean difference (MD) -1.48 days (95% CI, -2.61 to -0.36, P = 0.01) and the ventilation time: MD -8.99 hours (95% CI, -15.85 to -2.13, P = .01). On the contrary, hospital costs were more expensive for HCR: MD $3970 (95% CI, 2570-5370, P < .00001). All other comparisons were insignificant.
Conclusions:
In the short-term, HCR is as safe as conventional CABG and may offer certain benefits such as a lower requirement for blood transfusion and shorter hospital stays. However, HCR is more expensive than conventional CABG.
