Percutaneous coronary intervention in side branch coronary arteries: Insights from the Japanese nationwide registry

Figures

• 

  Fig. 1. A: The study flow chart. PCI: percutaneous coronary intervention. B: Scheme of location of major vessel (MV) and side branch (SB) in the coronary artery. The yellow and red labels indicate the MV and SB, respectively. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)

  Fig. 2. Adjusted odds ratio (OR) of the composite endpoint of in-hospital adverse events. A. Whole cohort. B. SB-PCI group: side branch PCI alone. C. SB + MV-PCI group: PCI for both side branch and adjacent major vessel. D. MV-PCI group: major vessel PCI alone. MI: myocardial infarction, PCI: percutaneous coronary intervention, LAD: left anterior descending artery, FFR: fractional flow reserve, DES: drug-eluting stent.

  Fig. 3. Left panel: Distribution of the frequency of each type of PCI in the institute. (a) SB-PCI alone, (b) SB and adjacent MV-PCI, (c) MV-PCI alone. Right panel: Stratification according to the institutional frequency of each PCI. Low-, moderate-, and high-frequency groups were divided according to the tertiles of the institutional frequency of each PCI. SB: side branch, MV: major vessel.

  Fig. 4. Adjusted odds ratio (OR) for composite endpoint of in-hospital adverse events according to the tertiles of the institutional frequency of each PCI in the multivariable analysis. Low-, moderate-, and high-frequency groups were divided according to the tertiles of the institutional frequency of each PCI indicated in Fig. 3.

  Fig. 5. Adjusted odds ratio (OR) for composite endpoint of in-hospital adverse events according to the tertiles of the institutional frequency of each PCI in the multivariable analysis. A. SB-PCI group: side branch PCI alone. B. SB + MV-PCI group: PCI for both side branch and adjacent major vessel. C. MV-PCI group: major vessel PCI alone.

  Fig. 6. Distribution of institutional frequency of the PCI for the restenotic lesion according to the tertiles of the institutional frequency of each PCI. Low-, moderate-, and high-frequency groups were divided according to the tertiles of the institutional frequency of each PCI indicated in Fig. 3. A. SB-PCI tertile: side branch PCI alone. B. SB + MV-PCI tertile: PCI for both side branch and adjacent major vessel. C. MV-PCI tertile: major vessel PCI alone.
