Insights
Radial access coronary angiography (RACA) detects myocardial bridges (MB) significantly more often than femoral access conventional coronary angiography (FACCA). This study found a 10.2% incidence of MB on RACA versus 1.8% on FACCA.
Area of Science:
- Cardiology
- Interventional Cardiology
- Diagnostic Imaging
Background:
- Myocardial bridge (MB) incidence is established via femoral access conventional coronary angiography (FACCA).
- The frequency of MB detection using radial access coronary angiography (RACA) remains unknown.
- Understanding MB prevalence across different angiography approaches is crucial for accurate diagnosis.
Purpose of the Study:
- To compare the incidence of myocardial bridges (MB) detected by RACA versus FACCA.
- To investigate the difference in MB detection rates between radial and femoral arterial access methods.
Main Methods:
- Retrospective analysis of 2500 patients undergoing RACA and 1455 patients undergoing FACCA.
- Detection and comparison of MB incidence between the two groups.
- Analysis of clinical and angiographic features in patients with MB.
Main Results:
- MB was detected in 10.2% of RACA patients versus 1.8% of FACCA patients (p < 0.001).
- The left anterior descending artery (LAD) mid-segment was the most commonly affected site for MB in both groups.
- Coronary artery disease (CAD) proximal to the MB was observed in 35.7% of cases, with no significant CAD detected in 69.8% of RACA patients with MB.
Conclusions:
- RACA demonstrates a significantly higher incidence of myocardial bridge detection compared to FACCA.
- The findings highlight the increased sensitivity of RACA in identifying myocardial bridges.
- Further research may explore the clinical implications of higher MB detection rates with RACA.
Background:
Although the incidence of myocardial bridge (MB) has been defined in different femoral access conventional coronary angiography (FACCA) studies, the frequency of MB on radial access coronary angiography (RACA) is unknown. The aim of this study was to determine the difference in the incidence of MB between patients undergoing RACA and FACCA.
Method:
A total of 2500 consecutive patients who underwent RACA and a total of 1455 consecutive patients who underwent FACCA were retrospectively investigated to detect the presence of MB. The incidences of the groups were calculated separately and compared. The clinical and angiographic features of the patients with MB were analyzed.
Results:
MB was detected at an incidence of 10.2%, in 255/2500 patients who underwent RACA, and 1.8% in 27/1455 patients who underwent FACCA (p < 0.001). In both RACA and FACCA patients, the most involved coronary artery was the left anterior descending artery (LAD) (86.9% and 93.1%) and the mid-segment (84.9% and 88.9%) was the most affected section. Co-involvement of multiple coronary arteries by MB was 7.8% in patients who underwent RACA and 7.4% in patients who underwent FACCA. Coronary artery disease (CAD) was determined in 111 (35.7%) of the coronary arteries with MB, of which 81.9% were proximal to the MB. No significant CAD was detected in any of the vessels of 69.8% (178/255) of the patients who underwent RACA for different clinical indications.
Conclusion:
These data demonstrated that the incidence of myocardial bridge able to be detected on RACA was much higher than FACCA.

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
