Direct true lumen cannulation in type A acute aortic dissection: A review of an 11 years’ experience
2020
ObjectivesDirect true lumen cannulation (DTLC) of the aorta is an alternative cardiopulmonary bypass cannulation technique in the context of type A acute aortic dissection (A-AAD). DTLC has been reported to be effective in restoring adequate perfusion to jeopardized organs. This study reports and compares operative outcomes with DTLC or alternative cannulation techniques in a large cohort of patients with A-AAD.MethodsAll patients who underwent surgery for A-AAD between January 2006 and January 2017 in Mainz university hospital were reviewed. The choice of cannulation technique was left to the operating surgeon, however DTLC was our preference in patients who were in state of shock or showe…
Effect of part-time cardiac catheterization facilities in patients with acute myocardial infarction
2017
Although the easy availability of invasive cardiac care facilities is associated with an increase in their use, their influence on outcomes is not clear. We sought to investigate whether a newly available cardiac catheterization laboratory (CCL) performing percutaneous coronary intervention (PCI) on a part-time (PT) basis might improve outcomes in patients with acute myocardial infarction (AMI).This was an observational cohort study that included all consecutive patients with AMI admitted to a secondary-level hospital in Spain before and after the PT-CCL opened in January 2006: during 1998-2005 and 2006-2014, respectively. All-cause in-hospital and long-term mortality were the co-primary en…
Limitations of Myocardial Blush Grade in the Evaluation of Myocardial Perfusion in Patients With Acute Myocardial Infarction and TIMI Grade 3 Flow
2006
Introduction and objectives An analysis was made of variability in the measurement of the angiographic index blush between a university hospital and an independent core laboratory, as well as its correlation with perfusion analised by intracoronary myocardial contrast echocardigraphy (MCE) and the ventricular function at the sixth month. Methods The study comprised 40 patients with a first ST-segment elevation myocardial infarction, single-vessel disease and open infarct-related artery. Perfusion was quantified by angiography (median fifth day, range 3-7) with blush in our laboratory and in an independent core laboratory. MCE was performed. Ejection fraction at the sixth month was determine…
High-Frequency rotablation of occluded coronary artery during heart catheterization
1989
High-frequency rotation atherectomy of an occluded left circumflex coronary artery was performed in a 45-year-old man. Over a 0.009 inch flexible tip steel wire a diamond-coated brass burr fasten to a flexible drive shaft that rotates and tracks was advanced. The drive shaft was connected to a turbine and driven by compressed air with 150,000 rpm. After rotablation of the posterior lateral branch over 3 cm with a 1.5 mm burr and rotablation with a 1.75 mm burr of the posterior branch of the left circumflex coronary artery the vessel was reopened with a smooth surface without perforation and dissection. 24 h control and 6 mo control revealed an open coronary vessel. High frequency rotating c…
Pulmonary vascular resistance as a potential marker of reactive pulmonary hypertension reduction following sildenafil therapy in patients disqualifie…
2019
Purpose:We sought to determine the predictors of restoration of heart transplantation (HTx) candidacy in pa-tients with systolic heart failure (HF) and reactive fixed pulmonary hypertension (RFPH) defined as pulmonaryvascular resistance (PVR) > 2.5 Wood units (WU), transpulmonary gradient (TPG) > 12 mmHg or ≤2.5 WUwith systolic arterial pressure ≤85 mmHg during vasoreactivity test, following sildenafil therapy.Material and methods:Between2007and20181136patientswereevaluatedatourdepartmentascandidatesforHTx. Thirty-five of them, who presented with systolic HF and were not eligible for HTx due to RFPH, wereincluded in the study (31 men aged 55.1 ± 7.4 years). In all the patients sildenafil wa…
Impact of obesity on adverse in-hospital outcomes in patients undergoing percutaneous mitral valve edge-to-edge repair using MitraClip® procedure - R…
2019
Background and aim: The number of percutaneous edge-to-edge mitral regurgitation (MR) valve repairs with MitraClip® implantations increased exponentially in recent years. Studies have suggested an obesity survival paradox in patients with cardiovascular diseases. We investigated the influence of obesity on adverse in-hospital outcomes in patients with MitraClip® implantation. Methods and results: We analyzed data on characteristics of patients and in-hospital outcomes for all percutaneous mitral valve repairs using the edge-to-edge MitraClip®-technique in Germany 2011–2015 stratified for obesity vs. normal-weight/over-weight. The nationwide inpatient sample comprised 13,563 inpatients under…
5-Year Experience of In-Hospital Outcomes After Percutaneous Left Atrial Appendage Closure in Germany
2019
The aim of this study was to evaluate 5-year in-hospital trends and safety outcomes of left atrial appendage (LAA) closure in the German nationwide inpatient sample.The safety and efficacy of percutaneous LAA closure have been demonstrated in randomized trials and prospective cohort studies, but results from large samples are missing.Data on patient characteristics and in-hospital safety outcomes for all percutaneous LAA closures performed in Germany between 2011 and 2015 were analyzed. Overall, 15,895 inpatients were included.The annual number of LAA occlusions increased from 1,347 in 2011 to 4,932 in 2015 (β = 1.00; 95% confidence interval [CI]: 0.95 to 1.01; p 0.001), with a nonsignifica…
12‐Month outcomes of transcatheter tricuspid valve repair with the PASCAL system for severe tricuspid regurgitation
2021
Objectives We investigated the durability of tricuspid regurgitation (TR) reduction and the clinical outcomes through 12 months after transcatheter tricuspid valve repair (TTVr) with the PASCAL Transcatheter Valve Repair System. Background TTVr has rapidly developed and demonstrated favorable acute outcomes, but longer follow-up data are needed. Methods Overall, 30 patients (age 77 ± 6 years; 57% female) received PASCAL implantation from September 2017 to May 2019 and completed a clinical follow-up at 12 months. Results The TR etiology was functional in 25 patients (83%), degenerative in three (10%), and mixed in two (7%). All patients had TR severe or greater (massive or torrential in 80%)…
Value of Echocardiographic Right Ventricular and Pulmonary Pressure Assessment in Predicting Transcatheter Tricuspid Repair Outcome
2020
The aim of this study was to assess the value of echocardiographic right ventricular (RV) and systolic pulmonary artery pressure (sPAP) assessment in predicting transcatheter tricuspid edge-to-edge valve repair (TTVR) outcome.RV dysfunction and pulmonary hypertension are associated with poor prognosis and are systematically sought during tricuspid regurgitation evaluation. The value of echocardiographic assessment in predicting TTVR outcome is unknown.Data were taken from the TriValve (Transcatheter Tricuspid Valve Therapies) registry, which includes patients undergoing TTVR at 14 European and North American centers. The primary outcome was 1-year survival free from hospitalization for hear…
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…
