• Registration Number: NCT05184075
• Lead Sponsor: Jessa Hospital

Brief Summary

Hybrid coronary revascularization (HCR), a combination of coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI), has emerged as an alternative treatment for multivessel coronary artery disease patients. However, the ideal sequence (PCI or CABG) is unclear.

The overall aim of this study is to investigate the best sequence within hybrid coronary revascularization using endoscopic coronary bypass grafting (i.e., first CABG then PCI versus first PCI then CABG)

Detailed Description

Hybrid coronary revascularization (HCR) is an emerging approach for multivessel coronary artery disease (MVD) which combines the excellent long-term outcomes of surgery with the early recovery and reduced short-term complications of percutaneous coronary intervention (PCI). However, the best sequence within hybrid coronary revascularization remains unclear. When CABG is performed first (standard HCR), incomplete revascularization can cause acute coronary events in the interim period. On the other hand, when PCI is performed first (reverse HCR), bleeding risks may be higher since CABG should be performed on uninterrupted dual anti-platelet therapy (DAPT). The use of minimally invasive surgery techniques is associated with reduced bleeding because of the less surgical trauma and may offer the opportunity to perform reverse HCR due to the possibility to reduce the risk of bleeding.

The overall aim of this study is to investigate the best sequence within hybrid coronary revascularization using endoscopic coronary bypass grafting (i.e., first CABG then PCI versus first PCI then CABG, figure 1)

Arm && Interventions

Group	Intervention	Description
Reverse hybrid coronary revascularization (HCR)	Reverse hybrid coronary revascularization	Patients will undergo reverse hybrid coronary revascularization. Moreover, quality of life is assessed at baseline, 14 days, 30 days, 90 days, 6 months and 1 year.
Standard hybrid coronary revascularization (HCR)	Standard hybrid coronary revascularization	Patients will undergo standard hybrid coronary revascularization. Moreover, quality of life is assessed at baseline, 14 days, 30 days, 90 days, 6 months and 1 year.

Primary Outcome Measures

Name	Time	Method
30-day net adverse clinical event (NACE)	From the first procedure until 30 days after the second procedure.	NACE consists of major adverse cardiac and cerebrovascular events (MACCE) and major bleeding unrelated to CABG (Bleeding Academic Research Consortium (BARC) type 3 and 5); MACCE consists of: * Death from any cause; * Myocardial infarction; * Stroke; * Target lesion revascularisation

Secondary Outcome Measures

Name	Time	Method
Key secondary outcome: 30-day major adverse cardiac and cerebrovascular events (MACCE)	From the first procedure until 30 days after the second procedure	MACCE consists of: * Death from any cause; * Myocardial infarction; * Stroke; * Target lesion revascularisation
Stent thrombosis	From the first procedure until one year after the second procedure	Stent thrombosis is subdivided into: * Definite stent thrombosis; * Probable stent thrombosis; * Possible stent thrombosis
Graft failure	From the first procedure until one year after the second procedure	Graft failure describes total graft occlusion that prevents blood flow through the graft to the revascularized part of the heart.
Key secondary outcome: 30-day major or clinically relevant non-major bleeding (BARC type 2, 3, 4, 5)	From the first procedure until 30 days after the second procedure	Major or clinically relevant non-major bleeding is assessed using BARC type 2, 3, 4, and 5.
Key secondary outcome: One-year net adverse clinical event (NACE)	From the first procedure until one year after the second procedure	NACE consists of major adverse cardiac and cerebrovascular events (MACCE) and major bleeding unrelated to CABG (Bleeding Academic Research Consortium (BARC) type 3 and 5); MACCE consists of: * Death from any cause; * Myocardial infarction; * Stroke; * Target lesion revascularisation
Key secondary outcome: one-year major adverse cardiac and cerebrovascular events (MACCE)	From the first procedure until one year after the second procedure	MACCE consists of: * Death from any cause; * Myocardial infarction; * Stroke; * Target lesion revascularisation
Quality of Life (QoL) using the Short-form 36 (SF-36) questionnaire	14, 30, 90, 180 and 365 days after the second procedure	QoL will be questioned with the Short-form 36 (SF-36) questionnaire.SF-36 scores range from 0 (worst) to 100 (best).
Revascularization	From the first procedure until one year after the second procedure	Revascularization is subdivided into: * Target lesion revascularization (TLR); * Target vessel revascularization (TVR)
Bleeding	From the first procedure until one year after the second procedure	Bleeding is assessed using the Bleeding Academic Research Consortium (BARC) classification, Thrombolysis In Myocardial Infarction (TIMI) bleeding classification and Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO). classification; BARC is subdivided into type zero (no bleeding) until five (probable/definite fatal bleeding), while the TIMI classification is divided into minimal, minor, and major. Gusto is subdivided into mild, moderate, and severe.
Key secondary outcome: One-year major or clinically relevant non-major bleeding (BARC type 2, 3, 4, 5)	From the first procedure until one year after the second procedure	Major or clinically relevant non-major bleeding is assessed using BARC type 2, 3, 4, and 5.
Quality of Life (QoL) using the Seattle Angina Questionnaire short-form (SAQ-7)	14, 30, 90, 180 and 365 days after the second procedure	QoL will be questioned with the Seattle Angina Questionnaire short-form (SAQ-7). The overall summary score ranges from 0 to 100 where higher ratings indicate a better health state.
Mortality	From the first procedure until one year after the second procedure	Both all-cause mortality as the subdivision in cardiovascular death, noncardiovascular death and undetermined cause of death are examined.
Myocardial infarction	From the first procedure until one year after the second procedure	Mycardial infarction is subdivided into: * Periprocedural; * Spontaneous
Stroke	From the first procedure until one year after the second procedure	Stroke is subdivided into: * Ischemic stroke; * Hemorrhagic stroke; * Non-specified stroke

Questions of the descriptive system are scored from one (no problem to perform activity) to five (severe problem/unable to perform activity). The scores are combined in order to calculate an index value (ranging from 0-1) that reflects the health state with one being the best health state. Moreover, the visual analogue scale ranges from 0 to 100 with 0 representing the worst health state and 100 the best health state.
Quality of Life (QoL) using the Rose Dyspnea Scale (RDS)	14, 30, 90, 180 and 365 days after the second procedure	The Rose Dyspnea Scale (RDS) will be used to assess Quality of Life. RDS is scored between zero and four. Zero corresponds to no dyspnea with activity and four to dyspnea that severly limits activity.
