The Association of Microalbuminuria With Aortic Stiffness Is Independent of C-Reactive Protein in Essential Hypertension
2009
BACKGROUND It has not been fully elucidated whether microalbuminuria (MAU) and high-sensitivity C-reactive protein (hsCRP) are associated with aortic distensibility independently of each other. Our study was aimed to evaluate the independent relationships of urinary albumin excretion rate (AER) and hsCRP with aortic stiffness in hypertensive patients. METHODS We enrolled 140 untreated nondiabetic essential hypertensives (mean age: 48 +/- 12 years). In all subjects, 24-hour AER and plasma levels of hsCRP were determined by immunoenzymatic assay. MAU was defined as an AER of 20-200 microg/min. Aortic stiffness was assessed by measurement of carotid-femoral pulse wave velocity (PWV). RESULTS C…
Acute Aortic Dissection Type A : Age-related Management and Outcomes Reported in the German Registry for Acute Aortic Dissection Type A (GERAADA) of …
2013
To determine the association between age and clinical presentation, management and surgical outcomes in a large contemporary, prospective cohort of patients with acute aortic dissection type A (AADA).AADA is one of the most life-threatening cardiovascular diseases, and delayed surgery or overly conservative management can result in sudden death.The perioperative and intraoperative conditions of 2137 patients prospectively reported to the multicenter German Registry for Acute Aortic Dissection Type A were analyzed.Of all patients with AADA, 640 (30%) were 70 years or older and 160 patients (7%) were younger than 40 years. The probability of aortic dissection extension to the supra-aortic ves…
Detection of dissection of the aortic intima and media after angioplasty of coarctation of the aorta. An angiographic, computer tomographic, and echo…
1990
Balloon coarctation angioplasty (BCA) was performed in eight patients (five male and three female) who were 14-49 years old (mean, 27.3 years) with isolated discrete unoperated coarctation of the aorta (n = 7) and postoperative recoarctation (n = 1). BCA was successful in seven of eight patients, resulting in a decrease in the gradient (64 +/- 19 to 16 +/- 13 mm Hg, p less than 0.01), an increase in the diameter at the coarctation site (0.9 +/- 0.4 to 1.6 +/- 0.4 mm, p less than 0.01). Follow-up (6 months) has demonstrated continued gradient relief (6 +/- 9 mm Hg) and diameter increase (1.6 +/- 0.2 cm). Monitoring was performed by transesophageal echocardiography (TEE) during BCA, and befor…
Assessment of chronic aortic dissection: contribution of different ECG-gated breath-hold MRI techniques.
2004
Our objective was to evaluate the impact of different rapid MRI techniques for the assessment and follow-up of chronic aortic dissections.Fifty-three patients (41 postoperative Stanford type A, 12 type B dissections) were scanned at 1.5 T during a 3-year period. The study reviewed ECG-gated breath-hold black blood sequences and 3D contrast-enhanced MR angiography of the thoracic aorta supplemented by segmented cine and phase-contrast imaging as well as abdominal contrast-enhanced MR angiography. A retrospective separate analysis of black blood acquisitions and contrast-enhanced MR angiograms from a total of 72 examinations was performed by two radiologists to evaluate detection of intimal f…
Relationships between mild hyperuricaemia and aortic stiffness in untreated hypertensive patients.
2013
Background and aims: Clinical studies exploring the relationship between serum uric acid (SUA) and arterial stiffness yielded conflicting results. Only in a few of these studies, arterial distensibility was examined by measuring aortic pulse wave velocity (PWV), which is considered the gold standard for evaluating arterial stiffness. In none of the previous investigations was the influence of SUA on aortic distensibility assessed, taking into account the effect of albuminuria. The purpose of our study was to comprehensively analyse the relationships between SUA and aortic PWV in a group of essential hypertensive patients. Methods and results: We enrolled 222 untreated and uncomplicated hype…
Association of renal resistive index with aortic pulse wave velocity in hypertensive patients
2014
Background: Recent data suggest that renal haemodynamic parameters obtained by duplex Doppler sonography, especially the intrarenal resistive index (RI), may be associated with systemic vascular changes. However, conflicting data exist about the independent relationship between aortic stiffness and RI. The aim of this study was to evaluate the relationship between RI and arterial stiffness, assessed by aortic pulse wave velocity (aPWV), in hypertensive patients. Design: Cross-sectional study. Methods: We enrolled 264 hypertensive subjects aged between 30 and 70 years. They were divided into two groups, either with normal renal function (n=140) or with chronic kidney disease (CKD) (n=124). E…
Relationship between aortic root size and glomerular filtration rate in hypertensive patients
2016
OBJECTIVE: Recent studies suggest that enlarged aortic root diameter (ARD) may predict cardiovascular events in absence of aneurysmatic alterations. Little is known about the influence of renal function on ARD. Our study was aimed to assess the relationships between glomerular filtration rate (GFR) and ARD in hypertensive subjects. METHODS: We enrolled 611 hypertensive individuals (mean age: 52 ± 15 years; men 63%). ARD was measured by echocardiography at the level of Valsalva's sinuses using M-mode tracings. It was considered as absolute measure, normalized to body surface area (ARD/BSA) and indexed to height (ARD/H). GFR was estimated by the Chronic Kidney Disease Epidemiology Collaborati…

Midterm Results of the Treatment of Penetrating Abdominal Aortic or Iliac Artery Ulcer with the BeGraft Balloon-Expandable Covered Stent-A Single-Cen…
2020
Background The purpose of the study was to evaluate the feasibility and efficacy of the novel BeGraft covered stent for the treatment of abdominal penetrating aortic ulcer (PAU) or penetrating ulcers of the iliac arteries (PUIAs). Methods This was a single-center observational study, which included 24 consecutive patients who underwent endovascular surgery due to abdominal PAU or PUIA between June 2017 and September 2019. Demographics of patients, lesion characteristics, diameter and length of the BeGraft stents, and postoperative events were prospectively collected and retrospectively analyzed. Follow-up examinations were performed at 1, 6, 12, and 24 months with clinical and hemodynamic e…
Long-term radiation exposure in patients undergoing EVAR: Reflecting clinical day-to-day practice to assess realistic radiation burden.
2018
Endovascular repair of aortic aneurysms (EVAR) has become an established treatment option currently applied in an increasing numbers of patients with aortic aneurysms. Advantages include reduced surgical trauma, procedural time, intensive care unit and hospital lengths of stay, blood loss as well as morbidity and mortality.The optimal imaging modalities in EVAR follow-up as well as the appropriate intervals between these follow-ups remain subject of controversial discussion. Objective of this study was the evaluation of the realistic radiation exposure and risk estimate postop EVAR treatment.Of the follow-ups required according to the surveillance schedule during the first year post-EVAR, o…
