A 78-year-old male smoker with known hyperlipidemia was referred for coronary angiography due to stable angina.
We performed coronary angiography using the right radial approach through a 6 Fr, 11 cm-long sheath that showed triple-vessel coronary artery disease with a chronic total occlusion at the proximal part of the left anterior descending (LAD) coronary artery. In order to plan our revascularization strategy and evaluate the LAD chronic total occlusion in more detail without a second arterial puncture, we decided to perform a “single-access dual injection.”
We exchanged the 6 Fr sheath with an 8 Fr, 11 cm-long sheath and two 4 Fr diagnostic catheters (JL3.5 and JR4) were inserted through the single radial sheath (Figures 1C-1E). We engaged both coronary ostia and dual injection was successfully performed (Figure 1F) with good image quality and adequate lesion evaluation.
To our knowledge, this is the first reported case of a dual injection using a single-sheath approach in order to evaluate a chronic total occlusion and plan a future intervention.
