Insights
Ad hoc intervention, performing coronary procedures in one session, offers convenience but its safety and cost-effectiveness require further evaluation. It is suitable for many patients but not universally appropriate.
Area of Science:
- Interventional Cardiology
- Cardiovascular Medicine
- Medical Procedure Optimization
Background:
- Historically, diagnostic cardiac catheterization and coronary intervention were performed separately.
- The practice of ad hoc intervention, combining both procedures in a single session, has increased due to patient convenience and physician efficiency.
- The safety, cost-effectiveness, and appropriate use criteria for ad hoc intervention remain subjects of ongoing discussion and research.
Purpose of the Study:
- To update the review on ad hoc intervention in coronary procedures.
- To provide suggestions for the appropriate use of ad hoc intervention as a routine strategy.
- To address the uncertainties regarding the safety and cost savings of ad hoc intervention.
Main Methods:
- Review of existing literature and clinical practices regarding ad hoc intervention.
- Analysis of convenience, efficiency, safety, and cost implications.
- Development of criteria for appropriate patient selection.
Main Results:
- Ad hoc intervention is convenient for patients and efficient for physicians.
- The safety and potential cost savings of ad hoc intervention are not definitively established.
- Ad hoc intervention is deemed reasonable for many patients but not universally appropriate or standard therapy.
Conclusions:
- Ad hoc intervention offers benefits but requires careful consideration of patient-specific factors.
- Establishing clear criteria for ad hoc intervention is crucial for its appropriate implementation.
- Further research is needed to fully ascertain the safety and economic advantages of this approach.
Abstract:
Coronary intervention may be combined with diagnostic cardiac catheterization or performed separately. In the early years of angioplasty, performing these procedures separately was standard practice. Gradually, ad hoc intervention (performing diagnostic angiography and coronary intervention within the same session) has become more common, largely because of its convenience for patients and efficiency for physicians. However, the safety and potential cost savings of this approach remain uncertain. Criteria for the appropriate use of ad hoc intervention have not been established. Ad hoc intervention is reasonable for many, but not appropriate for all patients and should not be considered standard therapy. This document updates an earlier review of this topic and provides suggestions for the use of ad hoc intervention as a routine strategy.
