Methods and results This case-control study comprised 55 acute anterior MI patients with LVT as cases and 55 acute anterior MI patients without LVT as controls, who were selected from a cohort of consecutive patients with ischemic heart failure in our hospital. The cases and controls were matched for age, sex, and left ventricular ejection fraction. LVT was detected by routine/contrast echocardiography or cardiac magnetic resonance imaging during the first 3 months following MI. Formation of apical aneurysm after MI was independently associated with LVT formation [72.0\% vs. 43.5\%, odds ratio (OR) = 5.06, 95\% confidence interval (CI) 1.65-15.48, P = 0.005]. Echocardiographic risk factors associated with LVT formation included reduced mitral annular plane systolic excursion (<7 mm, OR = 4.69, 95\% CI 1.84-11.95, P = 0.001), moderate-severe diastolic dysfunction (OR = 2.71, 95\% CI 1.11-6.57, P = 0.028), and right ventricular (RV) dysfunction [reduced tricuspid annular plane systolic excursion < 17 mm (OR = 5.48, 95\% CI 2.12-14.13, P < 0.001), reduced RV fractional area change < 0.35 (OR = 3.32, 95\% CI 1.20-9.18, P = 0.021), and enlarged RV mid diameter (per 5 mm increase OR = 1.62, 95\% CI 1.12-2.34, P = 0.010)]. Reduced tricuspid annular plane systolic excursion (<17 mm) significantly associated with increased risk of LVT in anterior MI patients (OR = 3.84, 95\% CI 1.37-10.75, P = 0.010), especially in those patients without apical aneurysm (OR = 5.12, 95\% CI 1.45-18.08, P = 0.011), independent of body mass index, hypertension, anaemia, mitral annular plane systolic excursion, and moderate-severe diastolic dysfunction. Conclusions Right ventricular dysfunction as determined by reduced TAPSE or RV fractional area change is independently associated with LVT formation in acute anterior MI patients, especially in the setting of MI patients without the formation of an apical aneurysm. This study suggests that besides assessment of left ventricular abnormalities, assessment of concomitant RV dysfunction is of importance on risk stratification of LVT formation in patients with acute anterior MI.}, language = {en} } @article{LiuHuLauetal.2021, author = {Liu, Dan and Hu, Kai and Lau, Kolja and Kiwitz, Tobias and Robitzkat, Katharina and Hammel, Clara and Lengenfelder, Bj{\"o}rn Daniel and Ertl, Georg and Frantz, Stefan and Nordbeck, Peter}, title = {Impact of diastolic dysfunction on outcome in heart failure patients with mid-range or reduced ejection fraction}, series = {ESC Heart Failure}, volume = {8}, journal = {ESC Heart Failure}, number = {4}, doi = {10.1002/ehf2.13352}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-258894}, pages = {2802-2815}, year = {2021}, abstract = {Aims The role of diastolic dysfunction (DD) in prognostic evaluation in heart failure (HF) patients with impaired systolic function remains unclear. We investigated the impact of echocardiography-defined DD on survival in HF patients with mid-range (HFmrEF, EF 41-49\%) and reduced ejection fraction (HFrEF, EF < 40\%). Methods and results A total of 2018 consecutive hospitalized HF patients were retrospectively included and divided in two groups based on baseline EF: HFmrEF group (n = 951, aged 69 ± 13 years, 74.2\% male) and HFrEF group (n = 1067, aged 68 ± 13 years, 76.3\% male). Clinical data were collected and analysed. All patients completed ≥1 year clinical follow-up. The primary endpoint was defined as all-cause death (including heart transplantation) and cardiovascular (CV)-related death. All-cause mortality (30.8\% vs. 24.9\%, P = 0.003) and CV mortality (19.1\% vs. 13.5\%, P = 0.001) were significantly higher in the HFrEF group than the HFmrEF group during follow-up [median 24 (13-36) months]. All-cause mortality increased in proportion to DD severity (mild, moderate, and severe) in either HFmrEF (17.1\%, 25.4\%, and 37.0\%, P < 0.001) or HFrEF (18.9\%, 30.3\%, and 39.2\%, P < 0.001) patients. The risk of all-cause mortality [hazard ratio (HR) = 1.347, P = 0.015] and CV mortality (HR = 1.508, P = 0.007) was significantly higher in HFrEF patients with severe DD compared with non-severe DD after adjustment for identified clinical and echocardiographic covariates. For HFmrEF patients, severe DD was independently associated with increased all-cause mortality (HR = 1.358, P = 0.046) but not with CV mortality (HR = 1.155, P = 0.469). Conclusions Echocardiography-defined severe DD is independently associated with increased all-cause mortality in patients with HFmrEF and HFrEF.}, language = {en} } @article{PetriLengenfelderVoelkeretal.2021, author = {Petri, Nils and Lengenfelder, Bj{\"o}rn and Voelker, Wolfram and Nordbeck, Peter}, title = {Interventional closure of aortomitral perforation after TAVR: A case report}, series = {Catheterization and Cardiovascular Interventions}, volume = {98}, journal = {Catheterization and Cardiovascular Interventions}, number = {3}, doi = {10.1002/ccd.29561}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-256625}, pages = {E483-E485}, year = {2021}, abstract = {Despite TAVR emerging as the gold standard for a broad spectrum of patients, it is associated with serious complications.
