Abstract Background A dedicated Heart Valve Unit was launched in 2018 to meet the demands of the growing transcatheter heart valve program by optimizing patient care in a single dedicated unit. Purpose To assess the performance of the heart valve unit (all steps of patient care in a single unit with intermediate care facilities) over a conventional approach (preparation on a normal ward, postprocedural intensive care unit (ICU) monitoring and transfer to an additional monitoring ward before discharge) in a high volume center. Methods Retrospective analysis including patients undergoing transcatheter mitral or tricuspid valve repair who were admitted to the Heart Valve Unit (02/2018–01/2020)…

Feasibility of a MPR-based 3DTEE guidance protocol for transcatheter direct mitral valve annuloplasty.

2020

Objectives Several interventional approaches have been established for the treatment of severe mitral regurgitation (MR) in patients at elevated risk for surgery. Direct annuloplasty is a relatively novel option in transcatheter mitral valve repair dedicated to reverse pathology in specific subsets of MR. With regard to echocardiographic guidance, this procedure presents with higher efforts in comparison with edge-to-edge therapy to enable safe and exact positioning of the device's anchors; evidence on optimal peri-interventional imaging is sparse. We tested a specific 3D-echo-guidance protocol implementing single-beat multiplanar reconstruction (MPR) and evaluated its feasibility. Methods …

Impact of atrial fibrillation on in-hospital mortality of ischemic stroke patients and identification of promoting factors of atrial thrombi – Result…

2019

Abstract Ischemic stroke is one of the leading causes of death and disability. Atrial fibrillation (AF) is a well-recognized risk factor for ischemic stroke. We aimed to investigate the impact of AF on in-hospital mortality of ischemic stroke patients and to identify parameters associated with intra-cardiac thrombogenic material. Patients were selected by screening the nationwide sample for ischemic stroke by ICD-Code (I63), stratified for AF. In this cohort, the association between in-hospital deaths and AF was investigated. In a second study, we performed a retrospective analysis of patients who underwent transesophageal echocardiography (TEE) for various reasons, assigned these to 2 grou…

Transgastric imaging-The key to successful periprocedural TEE guiding for edge-to-edge repair of the tricuspid valve.

2021

Intraprocedural transesophageal echocardiography (TEE) guidance plays an essential role in transcatheter repair therapy of the tricuspid valve (TV). So far, several different imaging concepts are in use. We propose an imaging protocol that fully addresses the morphological complexity of the TV and further offers efficacious workarounds for the frequently occurring restrictions of TV imaging in edge-to-edge repair of the TV. As a tertiary referral center with a large experience of more than 250 cases of transcatheter edge-to-edge repair (TEER) of the TV performed at the Heart Valve Center in Mainz/Germany, we have constantly adapted our peri-interventional echocardiographic approach to accom…

Association of transcatheter direct mitral annuloplasty with acute anatomic, haemodynamic, and clinical outcomes in severe mitral valve regurgitation.

2020

Abstract Aims Several approaches for transcatheter mitral valve repair for functional mitral valve regurgitation are established. Interventional direct annuloplasty is a novel trans‐venous, trans‐septal approach. While feasibility was proven recently, knowledge on its influence on cardiac dimensions, pressures, biomarkers, and clinical outcomes is sparse. Methods and results Patients consecutively treated with direct annuloplasty‐only procedures between December 2015 and April 2018 were included in this monocentric analysis. Echocardiographic measurements, biomarker levels, clinical status [New York Heart Association (NYHA) class and 6 min walk test] were assessed at baseline, at discharge,…

The risk factor age in normotensive patients with pulmonary embolism: Effectiveness of age in predicting submassive pulmonary embolism, cardiac injur…

2015

Abstract Introduction Right ventricular dysfunction (RVD), submassive pulmonary embolism (PE), elevated systolic pulmonary artery pressure (sPAP), elevated cardiac troponin I (cTnI) and old age are well-known risk factors for poor outcome in acute normotensive PE. The aim of this analysis was to calculate age cut-off values to predict submassive PE, cardiac injury, RVD and elevated sPAP in normotensive PE patients. Methods Retrospective analysis of clinical, laboratory, radiological and echocardiographic data of normotensive PE patients (2006–2011) was performed. Receiver operating characteristic (ROC) curves and Youden indexes were used to test the effectiveness of using patients' ages at …

Advanced Protocol for Three-Dimensional Transesophageal Echocardiography Guidance Implementing Real-Time Multiplanar Reconstruction for Transcatheter…

2019

Transcatheter direct annuloplasty has been introduced as a novel interventional treatment option for severe mitral valve regurgitation. Until now, only one direct annuloplasty device (Edwards Cardioband) has been commercially available, being implanted in more than 250 patients worldwide. Yet this procedure poses greater challenges regarding optimal fluoroscopic and echocardiographic guidance compared with edge-to-edge repair: correct localization and orientation of the anchors upon penetration into the fibrous mitral annulus tissue and the basal left ventricular myocardium are preconditions for an optimal result and essential to avoid damage of the neighboring structures (atrioventricular …

Early symptomatic benefit indicates long-term prognosis after transcatheter mitral valve edge-to-edge repair in functional and degenerative etiology

2021

Mitral regurgitation (MR) is common in patients with heart failure and constitutes an independent risk factor for adverse prognosis besides NYHA-class. The predictive value of dyspnea reduction after transcatheter mitral valve repair (TMVr) on outcome has not been investigated up to now.We enrolled 627 consecutive patients (47.0% female, 57.4% functional MR; median follow-up 486 days[IQR 157/961]; survival status available in 96.8%; symptoms assessed in n = 556 at baseline / n = 406 at 1 month) treated with isolated percutaneous mitral valve edge-to-edge repair in our center from 06/2010-03/2018 (exclusion of combined forms of TMVr) in a monocentric retrospective analysis. Survival was 97.6…

Predictors of short‐ and long‐term outcomes of patients undergoing transcatheter mitral valve edge‐to‐edge repair

2020

Objectives Transcatheter mitral valve repair (TMVR) by edge-to-edge therapy is an established treatment for severe mitral valve regurgitation (MR). Background Symptomatic and prognostic benefit in functional MR has been shown recently; nevertheless, data on long-term outcomes are sparse. Methods and results We analyzed survival of patients treated with isolated edge-to-edge repair from June 2010 to March 2018 (primarily combined edge-to-edge repair with other mitral valve interventions was excluded) in a retrospective monocentric study. Overall, 627 consecutive patients (47.0% females, 78.6 years in mean) were included. Leading etiology was functional MR (57.4%). Follow-up regarding surviva…

Impact of cancer on the effectiveness of cardiac Troponin I to predict right ventricular dysfunction in acute pulmonary embolism

2015

Background Deep vein thrombosis (DVT) and pulmonary embolism (PE) are connected with a poor outcome in cancer patients. We aimed to investigate the impact of cancer on the effectiveness of cardiac Troponin I (cTnI) to predict right ventricular dysfunction (RVD) in acute PE. Methods We retrospectively analyzed the data of 182 patients with confirmed PE. PE patients were subdivided into two groups: (i) with concomitant active cancer disease or history of cancer, and (ii) without known cancer. Receiver operating characteristic (ROC) curves with area under the curve (AUC) was calculated for cTnI predicting RVD and related cut-off levels for both groups. Results Thirty-seven PE patients (20.3%) …

Long-Term Outcome with New Generation Prostheses in Patients Undergoing Transcatheter Aortic Valve Replacement

2021

The aim of this study was to compare patients with transcatheter aortic valve replacement (TAVR) receiving new generation prostheses SAPIEN 3 (S3, Edwards Lifesc.) and Evolut R (ER, Medtronic Inc.) in terms of periprocedural and long-term outcome. Our retrospective, single-center analysis included 359 consecutive patients with severe aortic stenosis who underwent TAVR with S3 or ER from 2014–2016 (mean age 82 ± 7 years, 47% male, mean EuroSCORE II 8.0 ± 8%, mean follow-up 3.8 years). Device Success was equal (S3 93.0% vs. ER 92.4%, p = 0.812). We report a 30-day mortality of 2.8% in the S3 group, and 2.1% in the ER group (p = 0.674). There was no difference in stroke, conversion to open sur…

Percutaneous puncture of an aorto‐bifemoral bypass graft and successful closure with MANTA ® device in transfemoral TAVR

2021

Transfemoral aortic valve replacement (TAVR) has become a standard therapeutic option for patients with symptomatic severe aortic stenosis. Special anatomies can pose distinct challenges for vascular access and later closure of the access site, for example, in preoperated patients. Here, we elucidate a case of transfemoral TAVR with vascular access by direct puncture of an aorto-bifemoral bypass graft and illustrate the feasibility of vascular closure by an anchored collagen-plug vascular closure device (Teleflex MANTA® ).

Concomitant history of cancer in acute pulmonary embolism is connected with poorer outcome

2015

Abstract Purpose: Cancer increases the risk of venous thromboembolism (VTE) substantially. VTE is connected with poorer outcome in cancer patients. The aim of our study was to investigate the impact of cancer on the severity and short-term outcome of pulmonary embolism (PE). Methods: We retrospectively analyzed the data of 182 patients with confirmed PE. PE patients were subdivided in the group with concomitant active cancer disease or history of cancer or in the group without cancer. Groups were compared with Wilcoxon–Mann–Whitney Test. Logistic regression models were calculated to investigate the association between cancer and several parameters such as age and PE severity status as well …

State of the Art-High-Sensitivity Troponins in Acute Coronary Syndromes.

2020

In cases of suspected acute coronary syndrome (ACS), rapid and accurate diagnosis is essential to establish effective evidence-based medical treatment. Patients' history, clinical examination, 12-lead electrocardiogram, and cardiac biomarkers are cornerstones in initial management. Since high-sensitivity cardiac troponins were established, they have markedly expedited and revolutionized rule-in and rule-out pathways of patients with ACS and changed our everyday clinical practice. Thus, they have become an indispensable tool in daily routine in emergency units. This review focuses on historical and contemporary standards in laboratory biomarkers of myocardial injury and discusses their impli…

“Unlucky punch”: unexpected annular rupture during TAVR and successful treatment

2021

Although rare, annular rupture in TAVR is a feared and often unpredictable complication with relevant impact on in-hospital prognosis. Severe annular calcification is a common risk factor for annular rupture. We report on a case of annular rupture during TAVR with a balloon-expanded prosthesis in the absence of any annular calcification in the planning CT scan and illustrate the proposed pathomechanism as well as its successful immediate surgical management.

Transcatheter indirect mitral annuloplasty induces annular and left atrial remodelling in secondary mitral regurgitation

2020

Abstract Aims Mitral annuloplasty using the Carillon Mitral Contour System (CMCS) reduces secondary mitral regurgitation (SMR) and leads to reverse left ventricular remodelling. The aim of this study was to evaluate the effect of the CMCS on the mitral valve annulus (MA) and left atrial volume (LAV). Methods and results We retrospectively evaluated the data of all patients treated with the CMCS at our centre. Using transthoracic echocardiography, MA diameters were assessed by measuring the anterolateral to posteromedial extend (ALPM) and the anterior to posterior (AP) dimensions, respectively. Also, LAV and left ventricular end‐diastolic volume (LVEDV) were assessed. Patients were examined …

Obesity paradox in peripheral artery disease

2019

Background & aims: Previous studies have suggested an obesity survival paradox in patients with peripheral artery disease (PAD). We investigated the influence of obesity and underweight on adverse in-hospital outcomes in PAD. Methods: Patients diagnosed with PAD based on ICD-code I70.2 of the German nationwide database were stratified for obesity, underweight and a reference group with normal-weight/over-weight and compared regarding adverse in-hospital outcomes. Results: Between 01/2005-12/2015, 5,611,484 inpatients (64.8% males) were diagnosed with PAD; of those, 8.9% were coded with obesity and 0.3% with underweight. Obese patients were younger (70 (IQR 63/76) vs. 73 (66/80) years, P < 0…
