Hamburg AoRtic Valve cOhoRt (HARbOR)

January 9, 2020 updated by: Universitätsklinikum Hamburg-Eppendorf

Clinical Cohort Study - Hamburg AoRtic Valve cOhoRt

The primary aim of the study is to identify the optimal treatment modality for patients with aortic valve disease, incorporating the individual patient's risk profile and anticipated clinical outcomes. This includes the association of demographic factors, procedural data and biomarkers with clinical outcome in a prospective fashion.

Detailed Description

Patients with severe aortic valve disease have a poor prognosis under medical therapy, making replacement of the failing valve the preferred option. In addition to surgical aortic valve replacement (SAVR), transcatheter aortic valve implantation (TAVI) has evolved as an alternative treatment option for patients at intermediate and high operative risk. Before expansion of TAVI to low-risk and younger patients can be recommended, several questions remain to be investigated, e.g. optimal patient selection, periprocedural complications and long-term durability. Therefore every patient with a relevant aortic valve disease (aortic stenosis, aortic regurgitation or degenerative aortic valve prosthesis) who meets the inclusion/exclusion criterias is planned to be involved in the study.

Predictors of outcome are yet to be defined in patients with aortic valve disease in order to improve risk prediction for the different treatment modalities (medical, SAVR, TAVI).

The primary aim of the study is to identify the optimal treatment modality for the individual patient, incorporating the individual patient's risk profile and anticipated clinical outcomes. This includes the association of demographic factors, procedural data and biomarkers with clinical outcome in a prospective fashion.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
All cause mortality
Time Frame: one year
The primary aim of the study is to investigate all cause mortality after surgical aortic valve replacement or transcatheter aortic valve replacement. Events of death will be registered either from in-house information or telephone follow-up of the patient or the referring physician as part of clinical routine.
one year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Myocardial Infarction
Time Frame: 30 days after index procedure
Myocardial infarction based on a combination of clinical criteria, ecg changes indicative of new ischemia and a significant rise in cardiac biomarkers (peak value exceeding 15 x as the upper reference limit for troponin or 5 x for CK-MB) within the first 72 hours (periprocedural myocardial infarction) or 30 days (spontaneous myocardial infarction) after index procedure
30 days after index procedure
Stroke
Time Frame: 30 days after procedure
Assessment of clinical disability using a modified Rankin Scale (mRS) within the first 30 days after index procedure
30 days after procedure
Vascular complications and bleeding
Time Frame: 30 days after procedure
Evaluation of overt bleeding or vascular complications after index procedure by drop in haemoglobin and transfusion of packed red blood cells
30 days after procedure
Durability of the implanted aortic valve prosthesis
Time Frame: 10 years
Evaluation of long time durability of the implanted aortic valve prosthesis by echocardiography in the yearly follow up.
10 years
