J Cardiol 2024; 84:99-104. [PMID: 38307247 DOI: 10.1016/j.jjcc.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 01/20/2024] [Accepted: 01/25/2024] [Indexed: 02/04/2024]
Abstract
BACKGROUND In transcatheter aortic valve replacement (TAVR), complications may force the need for a surgical bailout, but knowledge is rare about outcomes in Germany. METHODS Using national health records, we investigated all TAVR in German hospitals between 2007 and 2020, focusing on 2018-2020. We extracted data on those interventions with need for a surgical bailout. RESULTS A total of 159,643 TAVR were analyzed, with an overall rate of surgical bailout of 2.30 %, an overall in-hospital mortality of 3.85 %, and in-hospital mortality in case of bailout of 16.51 %. The number of all annual TAVR procedures increased substantially (202 to 22,972), with the rate of surgical bailout declining from 27.23 to 0.61 % and overall mortality from 11.39 to 2.29 %. However, in-hospital mortality after bailout was still high (28.37 % in 2020). The standardized rates of overall mortality and surgical bailout between 2018 and 2020 were significantly lower for balloon-expandable and self-expanding transfemoral TAVR than for transapical TAVR after risk adjustment [transapical/transfemoral balloon-expandable/transfemoral self-expanding TAVR: in-hospital mortality: 5.66 % (95 % CI 4.81 %; 6.52 %)/2.30 % (2.03 %; 2.57 %)/2.32 % (2.07 %; 2.57 %); surgical bailout: 2.33 % (1.68 %; 2.97 %)/0.79 % (0.60 %; 0.98 %)/0.42 % (0.31 %; 0.53 %)]. Coronary artery disease [risk-adjusted OR = 1.50 (1.21; 1.85), p < 0.001] and atrial fibrillation [OR = 1.29 (1.07; 1.57), p = 0.009] were found to be the main risk factors for bailout. CONCLUSIONS Rates of TAVR with need for a surgical bailout and overall in-hospital mortality have declined noticeably over the years in Germany. However, the outcomes are still unfavorable after surgical bailout, as in-hospital mortality is continuously high. We present risk factors for surgical bailout to improve preparation of subsequent measures. It must be a major goal to further reduce the rate of surgical bailouts in the future.

Abstract
OBJECTIVE There has been a decline in hospital admission rates in many countries since the beginning of the COVID-19 pandemic. Patient selection differed from episodes before the pandemic. This study investigated changes in baseline characteristics as well as the short term mortality rate and probability of receiving an invasive procedure while considering sex disparities. METHODS Claims data provided by Germany's second largest insurance fund, BARMER, were used. Patients without COVID-19 who were treated for ST segment elevation myocardial infarction (STEMI), non-ST segment elevation myocardial infarction (NSTEMI), acute limb ischaemia (ALI), and stroke between 1 January 2018 and 31 December 2021 were included. Outcomes were compared separately for both sexes between the years before the pandemic (2018/2019) and during the pandemic (2020/2021). Propensity scores with exact matching were used to balance confounders including age, drug prescriptions in the previous year, federal state, month of admission, domiciliary care, and the Elixhauser comorbidities. Short term death and probability of invasive procedures were determined using cumulative incidence functions and Cox regressions. RESULTS The cohort consisted of 140 989 hospitalisations of 122 340 individual patients (48.3% female) with 102 960 matched cases. Baseline characteristics were similar between episodes in the unmatched cohort. Earlier discharge was observed for all strata except for males with ALI or STEMI, where the probability of early discharge was unchanged. The probability of receiving an invasive procedure was increased for both sexes with ALI, NSTEMI, and STEMI but not for stroke. The analyses suggested neither a statistically significant increase of the in hospital mortality rate nor the 30 day mortality rate after the pandemic started. CONCLUSION There was no evidence for a direct or indirect impact of the pandemic on major short term hospital outcomes. While the probability of receiving an invasive procedure increased for STEMI, NSTEMI, and ALI, the overall short term mortality rate was unaffected for both sexes.

Clin Res Cardiol 2023:10.1007/s00392-023-02299-w. [PMID: 37698619 DOI: 10.1007/s00392-023-02299-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 08/29/2023] [Indexed: 09/13/2023]
Abstract
BACKGROUND New and refined catheter based left atrial appendage (LAA) closure devices have been introduced in the past decade. The procedure can be performed using either an endocardial occlusion device or an epicardial loop stitch. We aimed to analyzed recent procedural safety. METHODS Catheter based LAA closures were identified in a complete nationwide German dataset via ICD and OPS codes from 2016 to 2020. RESULTS From 2016 to 2020, 28,039 endocardial and 213 epicardial occlusions were performed. Numbers of endocardial procedures increased from 5259 in 2016 to 5917 in 2020 (p = 0.020) in 387 centers with shifting of patients' characteristics towards older age (β = 0.29, p < 0.001), more heart failure (β = 1.01, p < 0.001) and renal disease (β = 0.67, p = 0.001) and without a significant trend for in-hospital safety except more bleeding (β = 0.12, p = 0.05). In-hospital major adverse cardiac and cerebrovascular events (MACCE) or pericardial puncture were independent on center procedure numbers. The loop stitch procedure was performed in 15 centers. Patients were younger (76.17 ± 8.16 vs. 73.16 ± 8.99, p < 0.001) and had a lower comorbidity index (2.29 ± 1.93 vs. 1.92 ± 1.64, p = 0.005). Adjusted risk difference for pericardial effusion (8.04%; 95% CI 3.01-13.08%; p = 0.002) and pericardial puncture (6.60%; 95% CI 3.85-9.35%; p < 0.001) was higher for the loop stitch procedure, while risk of bleeding (- 1.85%; 95% CI - 3.01 to - 0.69%; p = 0.002), intracerebral bleeding (- 0.37%; 95% CI - 0.59 to - 0.15%; p = 0.001) and shock (- 1.41%; 95% CI - 2.44 to - 0.39%; p = 0.007) was lower. No significant difference was observed for in-hospital MACCE. CONCLUSIONS Endocardial occlusion was the major catheter based LAA closure procedure in Germany without improvements in in-hospital safety from 2016 to 2020. In-hospital MACCE was independent on endocardial LAAC center volumes. Conclusions on the comparison between the two procedure types must be made cautious as the LAA loop stitch occlusion was utilized limited in a minor number of centers. Catheter based left atrial appendage closure in-hospital outcomes in Germany from 2016 to 2020.

Effect of fibrinolytic therapy on ST-elevation myocardial infarction clinical outcomes during the COVID-19 pandemic: A systematic review and meta-analysis. World J Cardiol 2023; 15:309-323. [PMID: 37397830 PMCID: PMC10308269 DOI: 10.4330/wjc.v15.i6.309] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 03/30/2023] [Accepted: 05/19/2023] [Indexed: 06/26/2023] Open
Abstract
BACKGROUND ST-elevation myocardial infarction (STEMI) is the result of transmural ischemia of the myocardium and is associated with a high mortality rate. Primary percutaneous coronary intervention (PPCI) is the recommended first-line treatment strategy for patients with STEMI. The timely delivery of PPCI became extremely challenging for STEMI patients during the coronavirus disease 2019 (COVID-19) pandemic, leading to a projected steep rise in mortality. These delays were overcome by the shift from first-line therapy and the development of modern fibrinolytic-based reperfusion. It is unclear whether fibrinolytic-based reperfusion therapy is effective in improving STEMI endpoints.
AIM To determine the incidence of fibrinolytic therapy during the COVID-19 pandemic and its effects on STEMI clinical outcomes.
METHODS PubMed, Google Scholar, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials were queried from January 2020 up to February 2022 to identify studies investigating the effect of fibrinolytic therapy on the prognostic outcome of STEMI patients during the pandemic. Primary outcomes were the incidence of fibrinolysis and the risk of all-cause mortality. Data were meta-analyzed using the random effects model to derive odds ratios (OR) and 95% confidence intervals. Quality assessment was carried out using the Newcastle-Ottawa scale.
RESULTS Fourteen studies including 50136 STEMI patients (n = 15142 in the pandemic arm; n = 34994 in the pre-pandemic arm) were included. The mean age was 61 years; 79% were male, 27% had type 2 diabetes, and 47% were smokers. Compared with the pre-pandemic period, there was a significantly increased overall incidence of fibrinolysis during the pandemic period [OR: 1.80 (1.18 to 2.75); I2= 78%; P = 0.00; GRADE: Very low]. The incidence of fibrinolysis was not associated with the risk of all-cause mortality in any setting. The countries with a low-and middle-income status reported a higher incidence of fibrinolysis [OR: 5.16 (2.18 to 12.22); I2 = 81%; P = 0.00; GRADE: Very low] and an increased risk of all-cause mortality in STEMI patients [OR: 1.16 (1.03 to 1.30); I2 = 0%; P = 0.01; GRADE: Very low]. Meta-regression analysis showed a positive correlation of hyperlipidemia (P = 0.001) and hypertension (P < 0.001) with all-cause mortality.
CONCLUSION There is an increased incidence of fibrinolysis during the pandemic period, but it has no effect on the risk of all-cause mortality. The low- and middle-income status has a significant impact on the all-cause mortality rate and the incidence of fibrinolysis.

Impact of the COVID-19 pandemic on aortic valve replacement procedures in Germany. BMC Cardiovasc Disord 2023; 23:187. [PMID: 37024779 PMCID: PMC10079149 DOI: 10.1186/s12872-023-03213-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Accepted: 03/29/2023] [Indexed: 04/08/2023] Open
Abstract
BACKGROUND COVID-19 has caused the deferral of millions of elective procedures, likely resulting in a backlog of cases. We estimate the number of postponed surgical aortic valve replacement (sAVR) and transcatheter aortic valve replacement (TAVR) procedures during the first two waves of the COVID-19 pandemic in Germany. METHODS Using German national records, all isolated TAVR and sAVR procedures between 2007 and 2020 were identified. Using weekly TAVR and sAVR procedures between 2017 and 2019, we created a forecast for 2020 and compared it with the observed number of procedures in 2020. RESULTS In Germany, a total of 225,398 isolated sAVR and 159,638 isolated TAVR procedures were conducted between 2007 and 2020 that were included in our analysis. The reduction in all AVR procedures (sAVR and TAVR) for the entire year 2020 was 19.07% (95%CI: 15.19-22.95%). During the first wave of the pandemic (week 12-21), the mean weekly reduction was 32.06% (23.44-40.68%) and during the second wave of the pandemic (week 41-52), the mean weekly reduction was 25.58% (14.19-36.97%). The number of sAVR procedures decreased more than the number of TAVR procedures (24.63% vs. 16.42% for the entire year 2020). CONCLUSION The first year of the COVID-19 pandemic saw a substantial postponing of AVR procedures in Germany. Postponing was higher for sAVR than for TAVR procedures and less pronounced during the second wave of the COVID-19 pandemic.

Abstract
Background In pure aortic regurgitation, transcatheter aortic valve replacement (TAVR) is not yet used on a regular base. Due to constant development of TAVR, it is necessary to analyze current data. Methods By use of health records, we analyzed all isolated TAVR or surgical aortic valve replacements (SAVR) for pure aortic regurgitation between 2018 and 2020 in Germany. Results 4,861 procedures-4,025 SAVR and 836 TAVR-for aortic regurgitation were identified. Patients treated with TAVR were older, showed a higher logistic EuroSCORE, and had more pre-existing diseases. While results indicate a slightly higher unadjusted in-hospital mortality for transapical TAVR (6.00%) vs. SAVR (5.71%), transfemoral TAVR showed better outcomes, with self-expanding compared to balloon-expandable transfemoral TAVR having significantly lower in-hospital mortality (2.41% vs. 5.17%; p = 0.039). After risk adjustment, balloon-expandable as well as self-expanding transfemoral TAVR were associated with a significantly lower mortality vs. SAVR (balloon-expandable: risk adjusted OR = 0.50 [95% CI 0.27; 0.94], p = 0.031; self-expanding: OR = 0.20 [0.10; 0.41], p < 0.001). Furthermore, the observed in-hospital outcomes of stroke, major bleeding, delirium, and mechanical ventilation >48 h were significantly in favor of TAVR. In addition, TAVR showed a significantly shorter length of hospital stay compared to SAVR (transapical: risk adjusted Coefficient = -4.75d [-7.05d; -2.46d], p < 0.001; balloon-expandable: Coefficient = -6.88d [-9.06d; -4.69d], p < 0.001; self-expanding: Coefficient = -7.22 [-8.95; -5.49], p < 0.001). Conclusions TAVR is a viable alternative to SAVR in the treatment of pure aortic regurgitation for selected patients, showing overall low in-hospital mortality and complication rates, especially with regard to self-expanding transfemoral TAVR.
