Die kardiologische Weiterbildung steht vor Herausforderungen wie der Verschiebung von stationären zu ambulanten Behandlungen, der Digitalisierung mit möglicherweise Abnahme von Untersuchungszahlen und begrenzter Diagnostikverfügbarkeit. Konflikte zwischen breiter internistischer Ausbildung und früher Spezialisierung sowie fehlende flexible Arbeitszeitmodelle und Integrationsprogramme für ausländische Fachkräfte erschweren die Ausbildungsorganisation und die Vereinbarkeit von Familie und Beruf. Um die Attraktivität der Kardiologie zu sichern, sind gezielte Maßnahmen und Tipps, wie in diesem Positionspapier zusammengefasst, zur Bewältigung dieser Herausforderungen entscheidend. Dazu gehören die sorgfältige Auswahl der Weiterbildungsstätte, regelmäßige Mentoren- und Mitarbeitergespräche sowie Networking, Mentoring und Supervision zur Verbesserung der Ausbildungsqualität. Flexible Weiterbildungspfade, Förderung von Geschlechter- und Familiengerechtigkeit sowie die Integration von Forschung, aber auch digitaler Technologien sind weitere wichtige Aspekte für eine zukünftig weiterhin erfolgreiche Weiterbildung in der Kardiologie und damit Sicherung deren Attraktivität als medizinisches Fachgebiet.

Objective:A sternum-sparing approach of minimally invasive total coronary revascularization via left anterior thoracotomy demonstrated promising early outcomes in unselected patients with coronary artery multivessel disease. Follow-up data are still missing. Methods:From November 2019 to September 2023, coronary artery bypass grafting via left anterior minithoracotomy on cardiopulmonary bypass and cardioplegic cardiac arrest was performed as a routine procedure in 392 consecutive, nonemergency patients (345 men; 67.0 ± 9.9 years; range, 32-88 years). All patients had multivessel coronary artery disease (77.6% 3-vessel-disease, 22.4% 2-vessel-disease, and 32.9% left main stenosis). Patients at old age (older than a 80 years, 12.5%), with severe left ventricular dysfunction (ejection fraction <30%, 7.9%), diabetes mellitus (34.9%), massive obesity (body mass index > 35, 8.9%), and chronic lung disease (17.1%) were included. Mean European System for Cardiac Operative Risk Evaluation II score was 2.9 ± 2.8. Mean midterm follow-up (100%) was 15.2 ± 10.7 months (range, 0.1-39.5 months). Results:Left internal thoracic artery (99.0%), radial artery (70.4%), and saphenous vein grafts (57.4%) were used, and 70.4% of patients received at least 2 arterial grafts. A total of 3.0 ± 0.8 anastomoses (range, 2-5 anastomoses) per patient were performed to revascularize the territories of left anterior descending (98.7%), circumflex (91.6%), and right coronary (70.9%) artery. Complete anatomical revascularization was achieved in 95.1%. At follow-up, all-cause-mortality, myocardial infarction, repeat revascularization, and stroke was 3.1%, 1.5%, 5.4%, and 0.7%, respectively. Overall major adverse cardiac and cerebrovascular events rate was 8.7%. Conclusions:This is the first report of midterm follow-up after routine sternum-sparing total coronary revascularization via left anterior thoracotomy for multivessel coronary artery disease with a high rate of multiple arterial grafting and complete anatomical revascularization. Outcome was favorable and similar to that of contemporary conventional coronary artery bypass grafting.

Background:Transcatheter Aortic Valve Implantation (TAVI) has emerged over time, reflected in appropriate adjustments in the European Society of Cardiology (ESC) guidelines in 2007, 2012 and 2017.Objective:The aim of this study was to analyze in-hospital outcomes after TAVI in the development within a single heart center over a period of 10 years depending on adjustments in the guidelines, infrastructural and procedural determinants.Methods:489 consecutive patients who underwent TAVI from 2010 and 2019 at our center were analyzed retrospectively. Patients were divided into 3 groups of different treatment circumstances depending on guidelines adjustments and local infrastructural progress (group 1: 2010-2015 (n = 132), group 2: 2016-2017 (n = 155), group 3: 2018-2019 (n = 202). The primary endpoint was defined as all-cause in-hospital mortality. Secondary endpoints were selected according to the Valve Academic Research Consortium (VARC)-2 definitions. Multivariate logistic regression analysis was performed to determine predictors of in-hospital mortality. Statistical significance was assumed for p < 0.05.Results:489 patients (346 (70.8 %) transfemoral and 143 (29.2 %) transapical) underwent TAVI. Comparing periods (group 1 vs. 2 vs. 3) age (82.1 ± 6.2 vs. 82.5 ± 4.8 vs. 81.1 ± 5.1 years, p = 0.012) and EuroSCORE II (8.4 ± 6.0 vs. 5.8 ± 4.9 vs. 5.5 ± 5.0 %, p < 0.001) declined over time. Rates of in-hospital mortality decreased significantly (9.1 % vs. 5.8 % vs. 2.5 %, p = 0.029), especially with observed-to-expected mortality ratios indicating a disproportionate decline of in-hospital mortality (1.08 vs. 1.00 vs. 0.45). Furthermore, post-procedural complications, such as acute kidney injury stage 3 (10.6 % vs. 3.2 % vs. 4.5 %, p = 0.016) and bleeding complications (14.4 % vs. 11.6 % vs 7.9 %, p = 0.165) decreased from group 1 to 3. However, rates of permanent pacemaker implantations (7.6 % vs. 11.0 % vs. 22.8 %, p < 0.001) increased, associated with a switch towards self-expanding valves (0.0 % vs. 61.3 % vs. 76.7 %, p < 0.001). Length of hospitalization as well as stay at intensive care and intermediate care unit could be reduced significantly during the observation period. In multivariate analysis age (OR: 1.103; 95 % CI: 1.013 - 1.202; p = 0.025), creatinine level before TAVI (OR: 1.497; 95 % CI: 1.013 - 2.212; p = 0.043), atrial fibrillation (OR: 2.956; 95 % CI: 1.127 - 7.749; p = 0.028) and procedure duration (OR: 1.017; 95 % CI: 1.009 - 1.025; p < 0.001) could be identified as independent predictors of in-hospital mortality.Conclusion:This study identified age, creatinine level before TAVI, the presence of atrial fibrillation and procedure duration as independent predictors for in-hospital mortality. Although these predictors decreased during the observation period, the decline in hospital-mortality was disproportionate, which was indicated by an observed-to-expected mortality ratio of 0.45 for the last observation period. However, it can be assumed that apart from patient-related factors, there were further institutional, technical and procedural developments, which ran in parallel and affected in-hospital mortality rates after TAVI.

Background: In the prospective, multicentre, randomised TARGET All Comers study, percutaneous coro-nary intervention (PCI) with the FIREHAWK biodegradable-polymer sirolimus-eluting stent (BP-SES) was non-inferior to the durable-polymer everolimus-eluting stent (DP-EES) for the primary endpoint of target lesion failure (TLF) at 12 months. Aims: We aimed to report the final study outcomes at 5 years. Methods: Patients referred for PCI were randomised to receive either a BP-SES or DP-EES in a 1:1 ratio in 10 European countries. Randomisation was stratified by centre and ST-elevation myocardial infarction (STEMI) presentation, and clinical follow-up extended to 5 years. The primary endpoint was TLF (com-posite of cardiac death, target vessel myocardial infarction [MI], or ischaemia-driven target lesion revascu-larisation). Secondary endpoints included patient-oriented composite events (POCE; composite of all-cause death, all MI, or any revascularisation and its components). Results: From December 2015 to October 2016, 1,653 patients were randomly assigned to the BP-SES or DP-EES groups, of which 93.8% completed 5-year clinical follow-up or were deceased. At 5 years, TLF occurred in 17.1% of the BP-SES group and in 16.3% of the DP-EES group (p=0.68). POCE occurred in 34.0% of the BP-SES group and 32.7% of the DP-EES group (p=0.58). Revascularisation was the most common POCE, occurring in 19.3% of patients receiving BP-SES and 19.2% receiving DP-EES, of which less than one-third was ischaemia-driven target lesion-related. In the landmark analysis, there were no dif-ferences in the rates of TLF and POCE between groups from 1 to 5 years, and these results were consistent across all subgroups. Conclusions: In an all-comers population requiring stent implantation for myocardial ischaemia, the BP-SES was non-inferior to the DP-EES for the primary endpoint of TLF at 12 months, and results were sustained at 5 years, confirming the long-term safety and efficacy of the FIREHAWK BP-SES.

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). Hospital volume and O/E were correlated by regression analyses and volume quartiles. 18 763 patients (age: 81.1 ± 1.0 years, mean EuroSCORE II: 6.9 ± 1.8%) and 22 137 patients (mean age: 80.7 ± 3.5 years, mean EuroSCORE II: 6.5 ± 1.6%) were analysed in 2018 and 2019, respectively. The average observed in-hospital mortality was 2.57 ± 1.83% and 2.36 ± 1.60%, respectively. Unadjusted in-hospital mortality was significantly inversely related to hospital volume by linear regression in both years. After risk adjustment, the association between hospital volume and O/E was statistically significant in 2019 (R2 = 0.049; P = 0.046), but not in 2018 (R2 = 0.027; P = 0.14). The variance of O/E explained by the number of cases in 2019 was low (4.9%). Differences in O/E outcome between the first and the fourth quartile were not statistically significant in both years (1.10 ± 1.02 vs. 0.82 ± 0.46; P = 0.26 in 2018; 1.16 0 .97 vs. 0.74 ± 0.39; P = 0.084 in 2019). Any chosen volume cut-off could not precisely differentiate between hospitals with not acceptable quality (>95th percentile O/E of all hospitals) and those with acceptable (O/E ≤95th percentile) or above-average (O/E < 1) quality. For example, in 2019 a cut-off value of 150 would only exclude one of two hospitals with not acceptable quality, while 20 hospitals with acceptable or above-average quality (25% of all hospitals) would be excluded.CONCLUSION:The association between hospital volume and in-hospital mortality in patients undergoing elective TF-TAVI in Germany in 2018 and 2019 was weak and not consistent throughout various analytical approaches, indicating no clinical relevance of hospital volume for the outcome. However, these data were derived from a healthcare system with restricted access to hospitals to perform TAVI and overall high TAVI volumes. Instead of the unprecise surrogate hospital volume, the quality of hospitals performing TF-TAVI should be directly assessed by real achieved risk-adjusted mortality.

Die Ambulantisierung bisher stationärer durchgeführter Eingriffe ist aufgrund der technischen Fortschritte bei vielen Eingriffen, des Pflegepersonalmangels, des Kostendrucks im Gesundheitswesen und der Ausrichtung auf Patientenbedürfnisse sinnvoll. Gerade die Kardiologie ist mit den zahlreichen, interventionellen Eingriffen und Geräteimplantationen in hohem Maße betroffen. Gleichzeitig nehmen Alter und Morbidität der Patienten aufgrund der demografischen Entwicklung zu, sodass die strukturellen, personellen und prozeduralen Aspekte, unter denen kardiologische Eingriffe ambulant durchgeführt werden sollen ohne die Patientensicherheit zu gefährden, definiert werden müssen. In diesem Positionspapier werden Kriterien für das deutsche Gesundheitssystem definiert, basierend auf dem aktuellen Stand der Wissenschaft und einem Expertenkonsensus. Die letzte Entscheidung, ob ein Eingriff ambulant durchführbar ist, sollte beim behandelnden Arzt verbleiben und gemeinsam mit dem Patienten getroffen werden („shared decision making“).

Fast alle Branchen suchen nach Lösungen für den Fachkräftemangel. Besonders eklatant ist er im Gesundheitswesen in einer Gesellschaft des langen Lebens sowie enormer diagnostischer und therapeutischer Fortschritte. Neue Medizinstudienplätze helfen erst mit erheblicher zeitlicher Verzögerung. Umso wichtiger ist eine stärkere Kooperation von Ärztinnen und Ärzten mit anderen qualifizierten Gesundheitsberufen. Insbesondere der Einsatz von Physician Assistants könnte uns erheblich entlasten – auch in der Kardiologie.

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. The number of TAVI procedures (DRG F98A +F98) and the in-hospital main diagnoses of aortic stenosis (ICD I35) in 2021 were analyzed at the level of county or federal state based on anonymized data from hospital reports, according to § 21 of the German hospital reimbursement law. The number of TAVI and aortic stenosis cases was projected for 2035 based on data from the German Federal Statistical Office on demographic developments. With quality assurance data from hospitals in 2019 and a route planner, the travel time to the next hospital performing TAVI (OPS 5‑35a.0) was calculated, and the consequence of a politically suggested minimum volume cut-off was analyzed. In 2021, a total of 26,506 TAVI procedures were reported with a mean number of TAVI per 100,000 inhabitants of 32 (range between federal states from 25 to 42). Among the 66,045 diagnoses of aortic stenosis, there was a variation per 100,000 inhabitants from 64 to 108 (mean 79) between federal states. Compared to 2021, an additional 8748 (+13

Coronary artery bypass grafting (CABG) via full sternotomy remains a very invasive procedure, often requiring prolonged recovery of the patient. We describe a novel, less invasive approach for totally arterial CABG via a small left anterior thoracotomy in a pilot series of 20 unselected patients. From January to March 2020, 20 consecutive patients (mean age 65.9 ± 9.2 years, 100% male, STS-score: 1.6 ± 2) underwent CABG using only arterial conduits via a small left anterior thoracotomy. Patients were operated on cardiopulmonary bypass with peripheral cannulation and transthoracic aortic cross-clamping. Pulling tapes encircling the great vessels, the arrested empty heart was rotated and moved within the pericardium to enable conventional anastomotic techniques especially on lateral and inferior wall coronary targets. In all patients, left internal mammary artery and radial artery were utilized for bypass with 3.3 ± 0.7 distal coronary anastomoses per patient. Anterior, lateral, and inferior wall territories were revascularized in 100%, 85%, and 70% of patients, respectively. Complete anatomical revascularization was achieved in 95% of patients. ICU stay was 1 day in 17 patients, and 14 of patients left the hospital within 8 days. There was no hospital death, no stroke, no myocardial infarction, and no repeat revascularization. In this pilot series of 20 patients, minimally invasive, totally arterial CABG with avoidance of sternotomy was technically feasible with favorable patient outcomes.
