Symptomatic atherosclerotic occlusive disease of all supra-aortic arch vessels treated with total aortic arch rerouting.
2011
We present an uncommon case of symptomatic atherosclerotic occlusive disease of all supra-aortic arch vessels and its surgical treatment by total aortic arch rerouting after endarteriectomy of all target vessels.
Feasibility of transcatheter aortic valve implantation in patients with coronary heights ≤7 mm: insights from the transcatheter aortic valve implanta…
2018
OBJECTIVES Transcatheter aortic valve implantation (TAVI) in patients with low coronary heights is generally denied but is not impossible. Information about these high-risk procedures is sparse. METHODS Since May 2008, data of more than 3000 patients who had TAVI were prospectively collected in the institutional TAVI Karlsruhe registry. Characteristics, peri- and postoperative outcome of patients with low coronary heights of ≤7 mm were analysed according to the Valve Academic Research Consortium-2. RESULTS Eighty-six patients with an average coronary height of 6.4 ± 1.1 mm (mean age 81.0 ± 5.3 years, logistic EuroSCORE I 19.6 ± 13.3%) were treated. TAVI was performed in 72 transfemoral (83.…
Pulmonary agenesis: Importance of the diagnosis
2010
Progress in the management of acute pulmonary embolism.
2015
Purpose of review Pulmonary embolism is a major contributor to global disease burden worldwide. The 2014 guidelines of the European Society of Cardiology, endorsed by the European Respiratory Society, emphasize the need for initial and advanced risk stratification as well as risk-adapted treatment to ensure the highest quality of care. This review summarizes the progress in pulmonary embolism diagnosis, risk assessment, and treatment. Recent findings Major advances of the past 12 months include age-related biomarker cutoff levels for optimising pulmonary embolism diagnosis and risk stratification; detection of (isolated) subsegmental pulmonary embolism by computed tomographic pulmonary angi…

Segmentation-Free Estimation of Aortic Diameters from MRI Using Deep Learning
2021
Accurate and reproducible measurements of the aortic diameters are crucial for the diagnosis of cardiovascular diseases and for therapeutic decision making. Currently, these measurements are manually performed by healthcare professionals, being time consuming, highly variable, and suffering from lack of reproducibility. In this work we propose a supervised deep-learning method for the direct estimation of aortic diameters. The approach is devised and tested over 100 magnetic resonance angiography scans without contrast agent. All data was expert-annotated at six aortic locations typically used in clinical practice. Our approach makes use of a 3D+2D convolutional neural network (CNN) that ta…
Procedural characteristics and outcomes following chronic total occlusion coronary intervention: pooled analysis from 5 registries.
2021
Background Recent improvement in clinical skills, technology and hardware has resulted in improved success rates with chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We performed a study level pooled analysis from the five largest registries of percutaneous coronary intervention (PCI) of CTO. Research design and methods We conducted pooled analysis of 9500 patients in registries and data on procedural characteristics, technical success, and MACCE was collected. Results A total of 9500 patients were included in the analysis. Mean age was 65.4 years with previous CABG in 24.8%, reattempt procedure in 24.8% and mean JCTO score was 2.2. Final wiring strategy in hybrid al…
Serous Detachment of the Retina: A Complication of Branch Retinal Vein Stenosis
2005
The author reports a case of serous detachment of the retina, which has developed in an eye with veno-venous collaterals, secondary to stenosis of a branch of the central retinal vein near the optic disc. This complication has not previously been described in this retinal vascular obstructive disease.
OPTICAL COHERENCE TOMOGRAPHIC FINDINGS IN BIETTI’S CRYSTALLINE TAPETORETINAL DYSTROPHY
2014
Purpose: To report the optical coherence tomography (OCT) findings of Bietti crystalline tapetoretinal dystrophy. Design: Observational case report. Methods: A subject with Bietti crystalline tapetoretinal dystrophy was evaluated with ophthalmoscopy, fluorescein angiography, and OCT (Stratus). Results: OCT showed thinning and hyporeflectivity of the outer nuclear layer in the macula due to photoreceptor degeneration. The retinal areas showing atrophy of the retinal pigment epithelium displayed greater penetration of the optical beam into the choroid and visualization of residual choroidal vessels. The hyperreflective band normally seen under the neurosensory retina was extremely wide when a…
Vascular complications on arterial puncture site after coronaric and peripheral angiography
2011
Il cateterismo cardiaco, l'angiografia coronarica e periferica e le procedure interventistiche sono tecniche contrastografiche che prevedono la visualizzazione radiografica dei vasi coronarici e periferici dopo l'iniezione selettiva di mezzo di contrasto radiopaco. Si tratta di tecniche relativamente sicure, anche se esiste un certo rischio di morbilità e mortalità. Nel nostro studio abbiamo valutato le varie complicanze mettendole in relazione con fattori demografici e clinici, terapie, caratteristiche della puntura e della procedura.
