Optimal Fluoroscopic Projections of Coronary Ostia and Bifurcations Defined by Computed Tomographic Coronary Angiography

Popis výsledku v původním jazyce

Objectives: The aim of this study was to define the optimal fluoroscopic viewing angles of both coronary ostia and important coronary bifurcations by using 3-dimensional multislice computed tomographic data. Background: Optimal fluoroscopic projections are crucial for coronary imaging and interventions. Historically, coronary fluoroscopic viewing angles were derived empirically from experienced operators. Methods: In this analysis, 100 consecutive patients who underwent computed tomographic coronary angiography (CTCA) for suspected coronary artery disease were studied. A CTCA-based method is described to define optimal viewing angles of both coronary ostia and important coronary bifurcations to guide percutaneous coronary interventions. Results: The average optimal viewing angle for ostial left main stenting was left anterior oblique (LAO) 37o, cranial (CRA) 22o (95% confidence interval [CI]: LAO 33o to 40o, CRA 19o to 25o) and for ostial right coronary stenting was LAO 79o, CRA 41o (95% CI: LAO 74o to 84o, CRA 37o to 45o). Estimated mean optimal viewing angles for bifurcation stenting were as follows: left main: LAO 0o, caudal (CAU) 49o (95% CI: right anterior oblique [RAO] 8o to LAO 8o, CAU 43o to 54o); left anterior descending with first diagonal branch: LAO 11o, CRA 71o (95% CI: RAO 6o to LAO 27o, CRA 66o to 77o); left circumflex bifurcation with first marginal branch: LAO 24o, CAU 33o (95% CI: LAO 15o to 33o, CAU 25o to 41o); and posterior descending artery and posterolateral branch: LAO 44o, CRA 34o (95% CI: LAO 35o to 52o, CRA 27o to 41o). Conclusions: CTCA can suggest optimal fluoroscopic viewing angles of coronary artery ostia and bifurcations. As the frequency of use of diagnostic CTCA increases in the future, it has the potential to provide additional information for planning and guiding percutaneous coronary intervention procedures.
