  Figure 2. Kaplan–Meier estimator plot of all-cause mortality for paclitaxel DCBs vs. second-generation DESs for de novo LMS disease. The number at risk is represented at the bottom. This shows no significant difference between the groups.

  Figure 3. Propensity-matched Kaplan–Meier survival plot for all-cause mortality for DCBs versus DESs. This shows no significant difference between the groups.

  Figure 4. Kaplan–Meier estimator analysis of cardiovascular mortality for paclitaxel DCBs vs. second-generation DESs for de novo LMS disease. It shows no significant difference between the groups.

  Figure 6. Kaplan–Meier estimator analysis of target vessel myocardial infarction for paclitaxel DCBs vs. second-generation DESs for de novo LMS disease. Due to the low event rate, it was not possible to calculate hazard ratios.

  Figure 7. Kaplan–Meier estimator analysis of repeat revascularisation for paclitaxel DCBs vs. second-generation DESs for de novo LMS disease. It shows no significant difference between the groups.

  Figure 11. LMS lesion requiring bail-out stenting after DCB. This patient had an appearance of a type B dissection however there was persistent contrast hang-up in the dissection, resulting in bailout stenting. Image (A): Lesion pre-treatment, Image (B): Type B linear dissection after DCB, Image (C): Lesion after final DES treatment.
