Transcatheter aortic valve implantation (TAVI) shows declining complication rates and favorable outcomes, even in high-risk patients. In 2017, TAVI mortality was comparable to surgical repair, with better results than previous years.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Transcatheter aortic valve implantation (TAVI) is increasingly the standard of care for severe aortic stenosis.
- Recent TAVI outcomes are favorable, even in patients with low procedural risk.
Purpose of the Study:
- To analyze TAVI procedure volume, complication rates, and in-hospital mortality in Germany in 2017.
- To compare transvascular TAVI (TV-TAVI) outcomes with isolated surgical aortic valve replacement (iSAVR) across different risk groups.
Main Methods:
- Analysis of all isolated aortic valve replacement procedures in Germany in 2017.
- Stratification of patients into risk classes (low, intermediate, high, very high) using the German Aortic Valve Score (AKL).
- Focus on transvascular TAVI (TV-TAVI) and comparison with iSAVR.
Main Results:
- 17,956 TV-TAVI and 9,011 iSAVR procedures were performed in 2017.
- TV-TAVI showed decreased arterial vascular complications (6.0% vs. 7.1%) and pacemaker implantations (9.6% vs. 11.4%) compared to 2016.
- In-hospital mortality was equal (2.7%) for TV-TAVI and iSAVR, with a more favorable observed-to-expected mortality ratio for TV-TAVI (0.89 vs. 1.14).
Conclusions:
- Major complication rates, including bleeding and pacemaker implantation, continue to decline for TV-TAVI.
- In 2017, TV-TAVI demonstrated an observed-to-expected mortality ratio below 1, indicating improved outcomes compared to previous years and iSAVR.
- TV-TAVI outcomes were favorable across all risk groups stratified by the German Aortic Valve Score.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
