Healthcare provision of transcatheter aortic valve implantation in Germany.

Background: Transcatheter aortic valve implantation (TAVI) for aortic stenosis in older patients is the standard of care with a well-established supply density in Germany. In the near future, healthcare reform is planned that may affect TAVI capacities. Therefore, it is important to know how political regulations may interfere with access to services and what the need for TAVI will be in the future, based on demographic trends.

OECD indicator 'AMI 30-day mortality' is neither comparable between countries nor suitable as indicator for quality of acute care.

Background: Hospital mortality after acute myocardial infarction (AMI, ICD-10: I21-I22) is used as OECD indicator of the quality of acute care. The reported AMI hospital mortality in Germany is more than twice as high as in the Netherlands or Scandinavia. Yet, in Europe, Germany ranks high in health spending and availability of cardiac procedures.

Transfemoral aortic valve implantation: procedural hospital volume and mortality in Germany.

Aims: Studies assessing transfemoral transcatheter aortic valve implantation (TF-TAVI) showed lower rates of in-hospital mortality at high-volume hospitals and minimum caseloads were recommended to assure quality standards.

Methods And Results: All patients in the German mandatory quality assurance registry with elective or urgent TF-TAVI procedures in 2018 and 2019 at 81 and 82 hospitals, respectively, were analysed. Observed in-hospital mortality was adjusted to expected mortality by the German AKL-KATH score (O/E) as well as by the EuroScore II (O/E2).

[Impact of COVID-19 on cardiac rehabilitation during the first year of the pandemic: A comparison of the performance numbers in Germany from 2019 and 2020].

Introduction: In Germany, the COVID-19 pandemic led to substantial changes in outpatient and acute clinical cardiac care and rehabilitation. To estimate the influence of the COVID-19 pandemic on cardiac rehabilitation in 2020, institutional performance was compared to the pre-pandemic year 2019.

Methods: The performance numbers from rehabilitation institutions were compared.

[Cardiac rehabilitation during the COVID-19 pandemic in Germany - a quick poll of the German Society of rehabilitation and Prevention of Heart and Circulation Diseases (DGPR)].

Background: In Germany, the COVID-19 pandemic has significantly changed cardiological care in both the outpatient and inpatient setting, including the cancellation of elective interventions. The investigation presented here was carried out in order to obtain information on the extent to which this also applies to cardiac rehabilitation facilities.

Methods: In August 2020, all 107 member institutions of the DGPR were contacted and asked to take part in an online survey containing 12 sets of questions on the topic.

Cardiac Rehabilitation in German Speaking Countries of Europe-Evidence-Based Guidelines from Germany, Austria and Switzerland LLKardReha-DACH-Part 1.

Background: Although cardiovascular rehabilitation (CR) is well accepted in general, CR-attendance and delivery still considerably vary between the European countries. Moreover, clinical and prognostic effects of CR are not well established for a variety of cardiovascular diseases.

Methods: The guidelines address all aspects of CR including indications, contents and delivery.

Long-term effects of a standardized feedback-driven quality improvement program for timely reperfusion therapy in regional STEMI care networks.

Aims: Current European Society of Cardiology guidelines state that repetitive monitoring and feedback should be implemented for ST-elevation myocardial infarction (STEMI) treatment, but no evidence is available supporting this recommendation. We aimed to analyze the long-term effects of a formalized data assessment and systematic feedback on performance and mortality within the prospective, multicenter Feedback Intervention and Treatment Times in STEMI (FITT-STEMI) study.

Methods: Regular interactive feedback sessions with local STEMI management teams were performed at six participating German percutaneous coronary intervention (PCI) centers over a 10-year period starting from October 2007.

[Postacute care after transcatheter aortic valve implantation (TAVI)].

With increasing age valvular heart disease is among the most frequent diseases of the heart. Relevant valvular disease impairs not only the long-term prognosis but also physical resilience, activities of daily living and the quality of life. In cases of middle to high-grade symptomatic cardiac defects, valve replacement or valve reconstruction is still the surgical procedure of choice; however, in recent years the transcatheter percutaneous aortic valve replacement (TAVI) procedure has become more prominent for the most frequent defect, aortic valve stenosis.

[Memorandum Registry for Health Services Research: Update 2019].

Health registries could be used to analyze questions concerning routine practice in healthcare. Therefore, registries are a core method in health services research. The German Network for Health Services Research (Deutsches Netzwerk Versorgungsforschung, DNVF) promotes the quality of registries by scientific exchange, organization of advanced training, and recommendations in the form of a memorandum "Registry for Health Services Research".

In-hospital outcomes after transcatheter or surgical aortic valve replacement in younger patients less than 75 years old: a propensity-matched comparison.

Aims: Randomised trials comparing transcatheter aortic valve replacement (TAVR) with surgical aortic valve replacement (SAVR) have included mainly elderly patients >80 years. The authors investigated comparative in-hospital outcomes of younger patients <75 years undergoing transfemoral (TF) TAVR or isolated SAVR.

Methods And Results: A total of 6,972 patients aged 65-74 years undergoing TF-TAVR or SAVR between 2013 and 2014 were identified from the observational German Quality Assurance Registry on Aortic Valve Replacement (AQUA), which comprises all TAVR and SAVR procedures performed in Germany.

Volume-outcome relationship with transfemoral transcatheter aortic valve implantation (TAVI): insights from the compulsory German Quality Assurance Registry on Aortic Valve Replacement (AQUA).

Aims: Previous studies have shown lower rates of in-hospital complications and mortality for patients undergoing surgical aortic valve replacement (sAVR) in high-volume compared with lower-volume hospitals. It was the aim of our study to analyse whether there is a similar volume-outcome relationship for transcatheter aortic valve implantation (TAVI), which is increasingly used in clinical practice.

Methods And Results: We analysed all patients with non-emergent transfemoral (TF) TAVI procedures performed in 2014 in 87 German hospitals.

In-hospital mortality in propensity-score matched low-risk patients undergoing routine isolated surgical or transfemoral transcatheter aortic valve replacement in 2014 in Germany.

Aims: Recent randomized trials have documented the superiority of TAVR-particularly via transfemoral access-over SAVR in patients with severe aortic stenosis considered to have a high or intermediate operative risk of death. We sought to assess in-hospital outcomes of patients with severe aortic stenosis and a low risk of operative mortality undergoing routine surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR).

Methods And Results: We performed a propensity-score matched comparison of all patients undergoing first-time treatment by SAVR or transfemoral TAVR (TF-TAVR) in 2014 in Germany who had a logistic EuroSCORE (logES) ≤ 10%, considered to reflect low surgical risk.

Outcomes of transfemoral transcatheter aortic valve implantation at hospitals with and without on-site cardiac surgery department: insights from the prospective German aortic valve replacement quality assurance registry (AQUA) in 17 919 patients.

Aims: Performing transcatheter aortic valve implantation (TAVI) at hospitals with only cardiology department but no cardiac surgery (CS) on-site is at great odds with current Guidelines.

Methods And Results: We analysed data from the official, prospective German Quality Assurance Registry on Aortic Valve Replacement to compare characteristics and in-hospital outcomes of patients undergoing transfemoral TAVI at hospitals with (n = 75) and without CS departments (n = 22). An interdisciplinary Heart Team was established at all centres (internal staff physicians at hospitals with on-site CS; in-house cardiologists and visiting cardiac surgical teams from collaborating hospitals at non-CS hospitals).

Cryoballoon or Radiofrequency Ablation for Paroxysmal Atrial Fibrillation.

Background: Current guidelines recommend pulmonary-vein isolation by means of catheter ablation as treatment for drug-refractory paroxysmal atrial fibrillation. Radiofrequency ablation is the most common method, and cryoballoon ablation is the second most frequently used technology.

Methods: We conducted a multicenter, randomized trial to determine whether cryoballoon ablation was noninferior to radiofrequency ablation in symptomatic patients with drug-refractory paroxysmal atrial fibrillation.

In-hospital outcome of transcatheter vs. surgical aortic valve replacement in patients with aortic valve stenosis: complete dataset of patients treated in 2013 in Germany.

Background: Transvascular (TV-AVI) or transapical (TA-AVI) aortic valve implantation (TAVI) is a treatment option for patients with aortic stenosis being at high or prohibitive risk for surgical aortic valve implantation (SAVR). Randomized data demonstrated that these subgroups can safely been treated with TAVI. However, a comparison of SAVR and TAVI in intermediate and low-risk patients is missing.

Influence of different approaches of aortic valve replacement on the incidence of post-operative delirium in intermediate risk patients - a matched pair analysis.

Objectives: Evaluation of the risk for post-operative delirium (POD) after surgical or transfemoral aortic valve replacement (AVR) as an additional decision parameter for the choice of treatment in patients with an EuroScore (ES) between 10% and 20%.

Background: POD is well known as a not infrequent side effect of cardiac surgery necessitating extracorporeal circulation. In Germany a tendency to treat patients with ES <20% with transfemoral AVR (TF) instead of surgical AVR (SAVR) was observed in 2013.

Coronary procedures in German hospitals: a detailed analysis for specific patient clusters.

Objectives: Evaluation of the classification of the patients with coronary procedures [CP: coronary angiography (CA) and/or percutaneous coronary intervention (PCI)] in Germany to provide valid data as a basis for the evaluation of resource planning and comparison of results from other countries.

Background: In the case of CP, most data are restricted to procedures related to acute coronary syndrome (ACS), either STEMI or NSTEMI, and does not cover the whole range of coronary angiographies and therapeutic procedures. To contribute to the clarification of this situation, our analysis was performed.

Rationale and Design of FIRE AND ICE: A multicenter randomized trial comparing efficacy and safety of pulmonary vein isolation using a cryoballoon versus radiofrequency ablation with 3D-reconstruction.

Background: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia imposing substantial morbidity and mortality. Catheter-based pulmonary vein isolation (PVI) using radiofrequency current (RFC) has become a standard treatment for drug-resistant and symptomatic paroxysmal AF (PAF). In recent years, the cryoballoon-based technique is increasingly used as a promising alternative with a short learning curve.

Should health insurers target prevention of cardiovascular disease? A cost-effectiveness analysis of an individualised programme in Germany based on routine data.

Background: Cardiovascular diseases are the main cause of death worldwide, making their prevention a major health care challenge. In 2006, a German statutory health insurance company presented a novel individualised prevention programme (KardioPro), which focused on coronary heart disease (CHD) screening, risk factor assessment, early detection and secondary prevention. This study evaluates KardioPro in CHD risk subgroups, and analyses the cost-effectiveness of different individualised prevention strategies.
