Insights
Multiple balloon catheters are frequently needed for percutaneous transluminal coronary angioplasty (PTCA) success. This study found no difference in success rates when using multiple catheters versus one, indicating high efficacy.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Percutaneous transluminal coronary angioplasty (PTCA) is a common procedure for treating coronary artery disease.
- The use of multiple balloon catheters in PTCA has become more frequent.
- Understanding the impact of multiple catheter use on PTCA outcomes is crucial.
Purpose of the Study:
- To evaluate the outcomes of percutaneous transluminal coronary angioplasty (PTCA) when multiple balloon catheters are utilized.
- To compare the success rates of PTCA using single versus multiple balloon catheters.
- To assess the safety and efficacy of multi-catheter PTCA procedures.
Main Methods:
- Analysis of 300 consecutive percutaneous transluminal coronary angioplasty (PTCA) cases.
- Categorization of PTCA based on single lesion, multiple lesions, or multiple vessels.
- Comparison of angiographic success rates and adverse events between cases using one versus two or more balloon catheters.
Main Results:
- Multiple balloon catheters were required in 37% of PTCA cases, with higher utilization in multivessel interventions (72%).
- Angiographic success rates were high and comparable: 95% for single-catheter cases and 95% for multiple-catheter cases.
- Emergency bypass surgery (1.7%) and mortality (0.6%) rates were low, with no significant difference related to the number of catheters used.
Conclusions:
- Contemporary percutaneous transluminal coronary angioplasty (PTCA) frequently necessitates the use of multiple balloon catheters.
- The utilization of multiple balloon catheters does not compromise angiographic success rates in PTCA.
- High success rates with multiple catheters suggest they are a valuable tool, potentially offsetting increased procedural costs.
Abstract:
In order to examine the outcome of utilizing multiple balloon catheters during the percutaneous transluminal coronary angioplasty (PTCA), 300 consecutive PTCAs were analyzed. PTCA was performed in a single lesion in 163 patients (54%), in multiple lesions in 52 patients (18%), and in multiple vessels in 85 patients (28%). A total of 488 balloon catheters were used (1.6/case, range 1-9) and in 112 cases (37%) > or = 2 catheters were used. Multiple balloon catheters were needed in 27 single lesion (17%), 24 multilesion (48%), and 61 multivessel (72%) cases (p < .05). There was no difference in the angiographic success rate in cases completed with 1 balloon catheter (238/251, 95%) compared to those requiring > or = 2 catheters (260/274, 95%). Emergency bypass was required in 5 patients (1.7%) and there were 2 deaths (0.6%). Thus, although contemporary PTCA frequently requires multiple balloon catheters for completion, success rates remain high and appear to offset the increased procedural expenses.
