Résumé
Percutaneous revascularization of coronary chronic total occlusions (CTO) has increased due to advances in technology and operator expertise. Quality of life (QoL) remains an important but understudied outcome following CTO revascularization. Our aim is to conduct a systematic review of the impact of CTO revascularization on QoL. We searched three databases (Ovid MEDLINE, EMBASE, EBM reviews) from January 1st, 1990 to May 17th, 2020. Studies reporting on the following QoL metrics post CTO revascularization were included: QoL subscale of the Seattle Angina Questionnaire (SAQ-QoL). The ROBINS-I tool and Cochrane risk of bias tool were used to critically assess for risk of bias. We identified 1476 articles, of which 21 articles met inclusion criteria. Three categories of studies were identified with distinct patient populations. In the first category (1 study), CTO patients treated with either PCI or CABG compared to medical therapy had a significant improvement in SAQ-QoL compared to baseline (PCI 54.2 to 74.3; CABG 56.1 to 78.0; p < 0.05). In the second category (1 study), CTO patients compared to non-CTO patients had similar improvements in SAQ-QoL post PCI (CTO baseline 53.2 to 80.3; non-CTO baseline 56.5 to 80.6; p < 0.05). Finally, a third category with only CTO patients treated with PCI to the CTO vessel included 19 studies, all of which on average showed a significant improvement in SAQ-QoL post successful PCI, compared to non-successful PCI. Despite the limited literature, revascularization of CTO vessel was generally associated with improvement in QoL. Quality of life (QoL) is an important but understudied outcome following CTO revascularization. We conducted a systematic review of the impact of CTO revascularization on QoL. Despite the limitations of a lack of enough randomized control trials and the small number of studies, our systematic review highlights a trend of improvement in QoL indices after revascularization of CTO.

BACKGROUND
Percutaneous revascularization of coronary chronic total occlusions (CTO) has increased due to advances in technology and operator expertise. Quality of life (QoL) remains an important but understudied outcome following CTO revascularization. Our aim is to conduct a systematic review of the impact of CTO revascularization on QoL.
METHODS
We searched three databases (Ovid MEDLINE, EMBASE, EBM reviews) from January 1st, 1990 to May 17th, 2020. Studies reporting on the following QoL metrics post CTO revascularization were included: QoL subscale of the Seattle Angina Questionnaire (SAQ-QoL). The ROBINS-I tool and Cochrane risk of bias tool were used to critically assess for risk of bias.
RESULTS
We identified 1476 articles, of which 21 articles met inclusion criteria. Three categories of studies were identified with distinct patient populations. In the first category (1 study), CTO patients treated with either PCI or CABG compared to medical therapy had a significant improvement in SAQ-QoL compared to baseline (PCI 54.2 to 74.3; CABG 56.1 to 78.0; p < 0.05). In the second category (1 study), CTO patients compared to non-CTO patients had similar improvements in SAQ-QoL post PCI (CTO baseline 53.2 to 80.3; non-CTO baseline 56.5 to 80.6; p < 0.05). Finally, a third category with only CTO patients treated with PCI to the CTO vessel included 19 studies, all of which on average showed a significant improvement in SAQ-QoL post successful PCI, compared to non-successful PCI.
CONCLUSION
Despite the limited literature, revascularization of CTO vessel was generally associated with improvement in QoL.
BRIEF SUMMARY
Quality of life (QoL) is an important but understudied outcome following CTO revascularization. We conducted a systematic review of the impact of CTO revascularization on QoL. Despite the limitations of a lack of enough randomized control trials and the small number of studies, our systematic review highlights a trend of improvement in QoL indices after revascularization of CTO.
