Aortic valve implantation High risk
Introduction The first transcatheter aortic valve implantation (TAVI) in the Czech Republic was performed in 2008, i.e. six years after
the first TAVI provided by A. Cribier and his team [1]. To assess the in-hospital and outcome data after TAVI, the Czech Association of Interventional Cardiology (former Working Group of Interventional Cardiology) of the Czech Society of Cardiology in collaboration with the European

Fig. 5 – Implantation procedure II. Observational Registries' Program (EORP) of the European Society of Cardiology founded a national online all comers Czech TAVI Registry in 2009. All Czech TAVI centres, except one, have been participating in the Registry representing more than 90% of all TAVI procedures in the Czech Republic. All data are anonymized and collected at the Institute of Biostatistics and Analyses of Masaryk University in Brno, Czech Republic. Based on the Czech law, there has been no need for the patients' informed consent. Description of the Czech TAVI program [2] development from 2008 till June 2016 and the in-hospital outcome after these exciting and lifesaving procedures for patients with symptomatic severe aortic stenoses is the aim of this analysis. Data from the
Czech TAVI Registry was included in several EORP TAVI Registry publications [3–5].
Results Total of 1532 TAVI procedures was enrolled (Fig. 1). Patients' characteristics is as follows: median age 80 years [67–89], females (53%), hypertension (88.1%), smoking (3.7%), diabetes (43.9%), ischemic heart disease (47.8%), history of acute myocardial infarction (22.9%), history of stroke and/or transient ischemic attack (17.3%), pulmonary disease (25.3%), previous cardiac surgery (27.7%) and percutaneous

coronary intervention (31.9%). The presence of symptoms and primary reasons for TAVI are shown in Figs. 2 and 3. The median logistic EuroSCORE of TAVI patients was 18.2 [5.1–48.5%] representing the predictive 30 day risk of death if the patient would undergo cardiac surgery. Median left ventricle ejection fraction (LVEF) was 60% and 18.4% of patients had LVEF 40% or less. Tricuspid aortic valve was found in majority of cases (89.6%), bicuspid aortic valve in 4.9% and in 5.5% there is a lack of data. Implantation
procedures are described in Figs. 4–6. Median and index aortic valve areas before versus after TAVI were 0.7 cm2 [0.1–1.1] and 0.4 cm2/m2 versus 1.9 cm2 [0–3.1] and 1.0 cm2/m2 [0–1.7], respectively. Immediate procedural outcome and complications are shown in Figs. 7 and 8, 5.3% of patients suffered severe mitral regurgitation after TAVI, severe paravalvular leak was detected in 1.0% of patients. In-hospital mortality was 3.9% and the reasons for death are described in Fig. 9. Majority of patients (71.9%) was discharged home.

Conclusion The TAVI program in the Czech Republic has shown its safety and high effectivity in the treatment of patients with symptomatic severe aortic stenoses. Despite a high-risk patients' population with a median logistic EuroSCORE 18.2, there was a relatively low in-hospital mortality 3.9%. The online all comers Czech TAVI Registry provides a nationwide reliable data that serve the TAVI operators to improve the quality of care.
