Hemodynamic Changes During Physiological and Pharmacological Stress Testing in Healthy Subjects, Aortic Stenosis and Aortic Coarctation Patients–A Sy…

2019

Introduction: Exercise testing has become a diagnostic standard in the evaluation and management of heart disease. While different methods of exercise and pharmacological stress testing exist, only little is known about their comparability. We aimed to assess hemodynamic changes during dynamic exercise, isometric exercise, and dobutamine stress testing at different stress intensities in healthy subjects and patients with aortic stenosis (AS) and aortic coarctation (CoA).Methods: A systematic literature search (PROSPERO 2017:CRD42017078608) in MEDLINE of interventional trials was conducted to identify eligible studies providing evidence of changes in hemodynamic parameters under different st…

Aortic pulse wave velocity in children with migraine: a case control study

2018

Background: Migraine has been associated with increased risk of cardiovascular (CV) accident like angina and myocardial infarction(1) . Vascular changes in migraineur traditionally may prevail in cranial blood district, but more likely it is a generalized vascular phenomenon.(2) Previous studies showed an increased aortic pulse wave velocity (aPWV), a direct measure of aortic stiffness and an independent predictor of stroke and CV disease, in young and middle-aged migraineurs(3) Here we hypothesized that, if associated with the pathogenetic bases of the disease, increased aPWV should be appreciable also in migraineurs children. Materials and Methods: : We studied 10 children with migraine w…

On the Modeling of Transcatheter Therapies for the Aortic and Mitral Valves: A Review

2022

Transcatheter aortic valve replacement (TAVR) has become a milestone for the management of aortic stenosis in a growing number of patients who are unfavorable candidates for surgery. With the new generation of transcatheter heart valves (THV), the feasibility of transcatheter mitral valve replacement (TMVR) for degenerated mitral bioprostheses and failed annuloplasty rings has been demonstrated. In this setting, computational simulations are modernizing the preoperative planning of transcatheter heart valve interventions by predicting the outcome of the bioprosthesis interaction with the human host in a patient-specific fashion. However, computational modeling needs to carry out increasingl…

La Sindrome Compartimentale Addominale (ACS) dopo chirurgia dell'Aneurisma dell'Aorta Addominale (AAA)

2009

Introduction: The Abdominal Compartment Syndrome (ACS) is a “condition in which increased tissue pressure in a confined anatomic space, causes decreased blood flow leading to ischaemia and dysfunction and may lead to permanent impairment of function” Materials and Methods: between june 2007 and june 2008 we treated surgically 23 cases of AAA (14 in election and 9 in emergency), with indirect intra-abdominal pressure (IAP) monitoring (intra-vescical catheter). Mean age was 68 (64-84) years. Mean transverse diameter was 6,2 cm (min 5,5 e max 9,0). Rise in IAP more then 20 mmHg was considered for surgical decompression. In 1 case we registered preoperatively IAP more than 20 mmHg treated with …

Endovascular treatment of spontaneous isolated abdominal aortic dissection

2016

Isolated abdominal aortic dissection is a rare clinical disease representing only 1.3% of all dissections. There are a few case series reported in the literature. The causes of this pathology can be spontaneous, iatrogenic, or traumatic. Most patients are asymptomatic and symptoms are usually abdominal or back pain, while claudication and lower limb ischemia are rare. Surgical and endovascular treatment are two valid options with acceptable results. We herein describe nine cases of symptomatic spontaneous isolated abdominal aortic dissection, out of which four successfully were treated with an endovascular approach between July 2003 and July 2013. All patients were men, smokers, symptomati…

Lithotripsy of Calcified Aortic Valve Leaflets by a Novel Ultrasound Transcatheter-Based Device

2022

The increasing incidence of calcific aortic valve disease necessitates the elaboration of new strategies to retard the progression of the pathology with an innovative solution. While the increasing diffusion of the transcatheter aortic valve replacements (TAVRs) allows a mini-invasive approach to aortic valve substitution as an alternative to conventional surgical replacement (SAVR) in an always larger patient population, TAVR implantation still has contraindications for young patients. In addition, it is liable to undergo calcification with the consequent necessity of re-intervention with conventional valve surgery or repeated implantation in the so-called TAVR-in-TAVR procedure.
