N1 - Funding Information:
The SYNTAX Extended Survival study was supported by the German Foundation of Heart Research. The SYNTAX trial, during 0- to 5-year follow-up, was funded by Boston Scientific. Both sponsors had no role in the study design, data collection, data analyses, and interpretation of the study data and were not involved in the decision to publish the final manuscript. The principal investigators and authors had complete scientific freedom. Dr Serruys has received personal fees from SMT, Philips/Volcano, Xeltis, Novartis, and Merillife. Dr Hara has received a grant for studying overseas from the Japanese Circulation Society and a grant from Fukuda Foundation for Medical Technology, outside the submitted work. Dr Morice is a CEO and shareholder of CERC, a contract research organization based in Paris, with no role in this trial. Dr Kappetein is an employee of Medtronic. All other authors have reported that they have no relationships relevant to the contents of this paper to disclose.

N2 - Objectives: The aim of this study was to assess 10-year all-cause mortality in patients with heavily calcified lesions (HCLs) undergoing percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Background: Limited data are available on very long term outcomes in patients with HCLs according to the mode of revascularization. Methods: This substudy of the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) study assessed 10-year all-cause mortality according to the presence of HCLs within lesions with >50% diameter stenosis and identified during the calculation of the anatomical SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) score among 1,800 patients with the 3-vessel disease and/or left main disease randomized to PCI or CABG in the SYNTAX trial. Patients with HCLs were further stratified according to disease type (3-vessel disease or left main disease) and assigned treatment (PCI or CABG). Results: The 532 patients with ≥1 HCL had a higher crude mortality rate at 10 years than those without (36.4% vs 22.3%; HR: 1.79; 95% CI: 1.49-2.16; P < 0.001). After adjustment, an HCL remained an independent predictor of 10-year mortality (HR: 1.36; 95% CI: 1.09-1.69; P = 0.006). There was a significant interaction in mortality between treatment effect (PCI and CABG) and the presence or absence of HCLs (Pinteraction = 0.005). In patients without HCLs, mortality was significantly higher after PCI than after CABG (26.0% vs 18.8%; HR: 1.44; 95% CI: 0.97-1.41; P = 0.003), whereas in those with HCLs, there was no significant difference (34.0% vs 39.0%; HR: 0.85; 95% CI: 0.64-1.13; P = 0.264). Conclusions: At 10 years, the presence of an HCL was an independent predictor of mortality, with a similar prognosis following PCI or CABG. Whether HCLs require special consideration when deciding the mode of revascularization beyond their current contribution to the anatomical SYNTAX score deserves further evaluation.
