Endograft repair of spontaneous infrarenal abdominal aortic dissection

2005

A 71-year-old man with a history of hypertension and a recent myocardial infarction experienced a sudden periumbilical and back pain. Abdominal tenderness was found at physical examination, with no changes in electrocardiogram and serial enzyme determinations. Computed tomographic angiography (CTA) showed a normal thoracic aorta, an infrarenal aortic dissection extending into the left common iliac artery and a contralateral iliac occlusive disease (A, Cover). Although antihypertensive therapy was administered, the patient had persistent pain; subsequently, he underwent endovascular repair with a bifurcated stent graft (Talent, Medtronic Ave, Santa Rosa, Calif) introduced via the left femora…

Three-Year Results of Repaired Barlow Mitral Valves via Right Minithoracotomy versus Median Sternotomy in a Randomized Trial

2012

<b><i>Objectives:</i></b> To clarify whether the results of repair of a complex mitral lesion (Barlow valve) at the intermediate-term follow-up are independent of the mode of surgical access [minithoracotomy vs. median sternotomy (MS)]. <b><i>Methods:</i></b> In a prospective randomized study of mitral repair for Barlow disease using either a minimally invasive (MI) approach or MS, we achieved an average follow-up of 3 years (echocardiography, physical examination and quality of life). Mitral repair was achieved with polytetrafluoroethylene chordal implantation for both leaflets. <b><i>Results:</i></b> Both groups inclu…

Rehabilitation and return to sport after bilateral open surgery for femoroacetabular impingement in a professional ice hockey player: A case report

2015

International audience; Background: The aim of this case report was to describe the rehabilitation and return to sport of a professional ice hockey player with symptomatic femoroacetabular impingement (FM) after bilateral open hip surgery.Case description: A 21-year-old professional ice hockey player with symptomatic FAT underwent bilateral surgical hip dislocations within a 6-week time period. After the second surgery (right hip), he experienced right hip pain due to iliotibial band dehiscence, which required additional revision surgery. The athlete underwent a standardized rehabilitation protocol. Hip muscle strength was objectively assessed during rehabilitation.Outcomes: Iliotibial band…

Haemodynamic predictors of a penetrating atherosclerotic ulcer rupture using fluid-structure interaction analysis

2013

We present preliminary data on the flow-induced haemodynamic and structural loads exerted on a penetrating atherosclerotic aortic ulcer (PAU). Specifically, one-way fluid-structure interaction analysis was performed on the aortic model reconstructed from a 66-year-old male patient with a PAU that evolved into an intramural haematoma and rupture of the thoracic aorta. The results show that elevated blood pressure (117 mmHg) and low flow velocity at the aortic wall (0.15 m/s(2)) occurred in the region of the PAU. We also found a low value of time-averaged wall shear stress (1.24 N/m(2)) and a high value of the temporal oscillation in the wall shear stress (oscillatory shear index = 0.13) in t…

Cardiac Injury in COVID-19–Echoing Prognostication∗

2020

Background Myocardial injury is frequent among patients hospitalized with coronavirus disease-2019 (COVID-19) and is associated with a poor prognosis. However, the mechanisms of myocardial injury remain unclear and prior studies have not reported cardiovascular imaging data. Objectives This study sought to characterize the echocardiographic abnormalities associated with myocardial injury and their prognostic impact in patients with COVID-19. Methods We conducted an international, multicenter cohort study including 7 hospitals in New York City and Milan of hospitalized patients with laboratory-confirmed COVID-19 who had undergone transthoracic echocardiographic (TTE) and electrocardiographic…

DNA Content and Synthesis in Several Tissues and Variation of Moulting Hormone-Level in Gryllus bimaculatus DEG (Ensifera, Insecta)

1983

The mode of growth of several tissues in Gryllus bimaculatus was investigated during postembryonic development by cytophotometric methods. In contrast to the situation in holo- metabolous insects, the tissues growing by endomitosis reach only moderate levels of polyploidy. In this case the growth of tissues is achieved by mitotic divisions of small cells with subsequent polyploidization. The time courses of DNA synthesis were measured within the 3rd and, for comparison, the 8th larval instar by incorporation of labelled thymidine followed by autoradiography. Hemocytes, cells of the regeneration crypts of the midgut, gonads and nervous tissue showed a continuous incorporation rate; by contra…
