DCBNORWICH: Outcomes of Drug Coated Balloon Angioplasty, A UK Real Life Experience From 2009 to 2015
Study Details
Study Description
Brief Summary
This is a single center, retrospective, observational cohort study to assess the safety and efficacy of drug coated balloon (DCB) angioplasty in all forms of coronary artery disease. The Investigators intend to report outcomes of all patients who received DCB angioplasty at their center during the above mentioned period for up to 10 years.

Detailed Description
The Investigators expect to assess outcomes of all patients who received Drug Coated Balloon Angioplasty treatment, which is a novel therapy as opposed to standard Drug Eluting Stent insertion, for all types of coronary artery disease from 01/01/2009 till 31/12/2015 in their center. The Investigators believe the number exceeds 1000 patients.
The Investigators plan to collect demographic and procedural data from their existing data base. They will request up to date follow-up events from NICOR (National Institute for Cardiovascular Outcomes Research, UK) in 2017(data ending December 2016), by which time all patientswould have had minimum of 12 months follow up. The Investigators plan to incorporate these findings to their data set and report the comprehensive outcomes. Primary end point will be major adverse cardiac outcomes (MACE) defined as a composite of death, myocardial infarction and target vessel revascularisation. Secondary end points will be acute vessel closure and target lesion revascularisation. The Investigators also have a long term plan of requesting follow-up events from NICOR for up to 10 years, so they can report on long term outcomes of drug coated balloon treatment.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Patients treated with DCB angioplasty Patient cohort is comprised of all patients who received drug coated balloon angioplasty at NNUH during the above period. Within this cohort there will be two main groups which are drug coated balloon (DCB) angioplasty for de novo coronary artery disease (CAD) and DCB angioplasty for ISR/ST. Graft cases will be reported as a small third group. Outcomes will also be reported for three sub groups of de novo disease group, namely, dcb-only angioplasty for de novo disease, dcb-only angioplasty as primary percutaneous coronary intervention (PPCI) and dcb-only angioplasty group using a DCB with a diameter of 3mm or more in de novo disease. |
Device: Drug coated balloon angioplasty
Drug coated balloons are semi compliant percutaneous coronary angioplasty balloons coated with a chemotherapeutic drug such as Paclitaxel used with an excipient which allows rapid absorption to vessel wall upon balloon expansion for 30-60s. This allows coronary angioplasty without any permanent or semi- permanent stent or scaffold provided there are no vessel threatening dissections or significant acute recoil.

Outcome Measures
Primary Outcome Measures
- Major adverse cardiac events (MACE) defined as a composite of all cause death, myocardial infarction and target vessel revascularisation for 12 months and then up to 10 years [12 months and then up to 10 years]
Death. All cause death will be defined as death due to any cause. . Target vessel revascularisation (TVR) A TVR is defined as any repeat percutaneous intervention or surgical bypass of any segment of the target vessel. The latter is defined as the entire major coronary vessel proximal and distal to the target lesion, including upstream and downstream branches and the target lesion itself.
- Myocardial Infarction (MI) [12 months and then up 10 years]
An MI is defined as an episode of chest pain with positive cardiac enzyme troponin as per MINAP definition (a hospital diagnosis reported as a troponin positive MI).
- Target Vessel Revascularisation (TVR) [12 months and then up to 10 years]
A TVR is defined as any repeat percutaneous intervention or surgical bypass of any segment of the target vessel. The latter is defined as the entire major coronary vessel proximal and distal to the target lesion, including upstream and downstream branches and the target lesion itself.
Secondary Outcome Measures
- Acute vessel closure and target lesion revascularisation for 12 months and then up to 10 years. [12 months and then up to 10 years]
Acute Vessel Closure Acute vessel closure is defined as an event where a patient had to be taken back to cardiac catheterisation lab and require repeat angioplasty (during the same hospital stay) for a complete or partial occlusion of the artery due to a dissection. TLR A TLR is defined as any repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion. The target lesion is defined as the treated segment from 5 mm proximal and 5 mm distal to the treated lesion (by visual assessment).
- TLR [12 months and then up to 10 years]
A TLR is defined as any repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion. The target lesion is defined as the treated segment from 5 mm proximal and 5 mm distal to the treated lesion (by visual assessment).
