Abstract
No data exist about successful percutaneous coronary intervention (PCI) and clinical outcome in patients with multiple coronary chronic total occlusions (CTOs). The aim of this study was to determine the impact on cardiac mortality of PCI of multiple CTOs. The Florence CTO PCI registry includes patients treated with drug-eluting stent for at least 1 CTO. From this registry, we examined consecutive patients with ≥2 CTOs. Patients were stratified into successful PCI of all attempted CTOs and partially successful PCI (1 CTO PCI successful) or failed PCI (no CTO PCI success) groups. The primary end point of the study was cardiac mortality. Of 1,035 patients with CTO, 120 (11.6%) underwent PCI for ≥2 CTOs for a total of 249 CTOs. CTO PCI was successful in 195 CTOs (78.3%), and in 76 patients (63.3%), PCI was successful in all attempted lesions, whereas in 34 patients, CTO PCI was partially successful and in 10, completely unsuccessful. Cardiac mortality at 12 months was lower in the CTO PCI success group than CTO PCI failure or partial success group (1.3% vs 11.3%; p = 0.025). The 2-year survival rate was lower in patients with a complete coronary revascularization compared with those with incomplete revascularization (96 ± 3% vs 78 ± 7%; p = 0.002); completeness of revascularization was inversely related to the risk of death (hazard ratio 0.10; p = 0.029). In patients with multiple CTOs, a successful PCI of all CTOs was associated with increased survival and completeness of revascularization was a strong predictor of survival.

Meta-Analysis of Effect on Mortality of Percutaneous Recanalization of Coronary Chronic Total Occlusions Using a Stent-Based Strategy
American Journal of Cardiology
Volume 111, Issue 4 , Pages 521-525, 15 February 2013
We performed a systematic review and meta-analysis comparing the all-cause mortality outcomes of successful percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) with unsuccessful CTO-PCI, using a stent-based strategy. Multiple studies comparing successful CTO-PCI with unsuccessful CTO-PCI have reported variable outcomes. No systematic review or meta-analysis has been performed after stenting became the default strategy for CTO-PCI. Searching major electronic databases, 64 studies were identified using the keywords “CTO,” “PCI,” and “mortality.” Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses method, 13 studies met the criteria for inclusion in the present meta-analysis. The short-term (≤30 days) and long-term (≥1 year) mortality outcomes were analyzed comparing successful CTO-PCI and unsuccessful CTO-PCI. Coronary perforation and its association with CTO-PCI success was analyzed. A significant reduction in short-term mortality was noted with successful CTO-PCI compared to unsuccessful CTO-PCI (odds ratio 0.218, 95% confidence interval 0.095 to 0.498, Z = −3.61, p <0.001). A similar, significant reduction in long-term mortality was noted with successful CTO-PCI compared to unsuccessful CTO-PCI (odds ratio 0.391, 95% confidence interval 0.311 to 0.493, Z = −7.957, p <0.001). A significant association was present between coronary perforation and unsuccessful CTO-PCI (odds ratio 0.168, 95% confidence interval 0.104 to 0.271, Z = −7.333, p <0.001). In conclusion, successful CTO-PCI using a predominantly stent-based strategy is associated with a significant reduction in short- and long-term mortality compared to unsuccessful CTO-PCI. Coronary perforation was associated with CTO-PCI failure.:ab:

Если честно, я ничего не понял, хотя формально английский понимаю. Через год результаты в группе успешных реваскуляризаций лучше, это понятно. А что происходит через 2 года? 2-летняя выживаемость хуже в группе полной реваскуляризации??? И проценты в скобках тогда не соответствуют тексту.
Или я совсем английскому разучился?

Дима, у Вас же доступ к АмКардиолоджи есть? Вам и флаг в руки :)
