Automating the determination of wave speed using the pu-loop method [PDF]

, 2005
The PU-loop (pressure-velocity loop) is a method for determining wave speed and relies on the linear relationship between the pressure and velocity in the absence of reflected waves.

Inflammatory aneurysm of the ascending aorta [PDF]

European Journal of Cardio-Thoracic Surgery, 2006
Inflammatory aneurysms of the aorta are usually seen in the infrarenal abdominal aorta and very rarely in the ascending aorta. We present the case of a 76-year-old male with inflammatory aneurysm of the ascending aorta.

Old Myths, New Concerns: the Long-Term Effects of Ascending Aorta Replacement with Dacron Grafts. Not All That Glitters Is Gold

Journal of Cardiovascular Translational Research, 2016
Synthetic grafts are widely used in cardiac and vascular surgery since the mid-1970s. Despite their general good performance, inability of mimicking the elastomechanical characteristics of the native arterial tissue, and the consequent lack of adequate ...

Ultrasound compared to Computed Tomography in identifying thoracic aortic aneurysms in patients with Giant Cell Arteritis

Arthritis Care &Research, Accepted Article.
Objectives The objectives of this study were to evaluate the correlation and agreement between ultrasound and computed tomography (CT) in measuring ascending aorta diameter in patients with giant cell arteritis (GCA) and to investigate the development of new ascending aortic aneurysms in patients with newly diagnosed GCA. Methods To achieve the primary

Tuberculous pseudoaneurysm of the ascending aorta [PDF]

BMJ Case Reports, 2015
Increase in the incidence of drug resistance and association with HIV has led to a resurgence of tuberculosis. However, tubercular arteritis continues to remain a rare entity with a prelidection for the thoracic aorta. We report a tubercular ascending aortic pseudoaneurysm in a patient already on treatment for disseminated tuberculosis who underwent ...

Soft Beats: A Dielectric Elastomer‐Based Ventricular Assist Device for Next‐Gen Heart Failure Management

Advanced Engineering Materials, EarlyView.
The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,

Efficacy of endovascular repair in the treatment of retrograde ascending aortic intramural haematoma

Journal of Cardiothoracic Surgery, 2023
Background The current treatment for retrograde ascending aortic intramural hematoma (RAIMH) remains challenging. This study aims to summarize the short-term results of endovascular repair in the treatment of retrograde ascending aortic intramural ...

Epithelioid hemangioma of the ascending aorta: A rare case

Indian Journal of Pathology and Microbiology, 2022
Cardiac epithelioid hemangioma is extremely rare. Currently, there are only a few described cases of intraluminal hemangiomas of the aorta and the aortic valve and no described cases with extraluminal epithelioid hemangiomas of the ascending aorta.

Fluid–structure interaction simulations outperform computational fluid dynamics in the description of thoracic aorta haemodynamics and in the differentiation of progressive dilation in Marfan syndrome patients [PDF]

Royal Society Open Science, 2020
Abnormal fluid dynamics at the ascending aorta may be at the origin of aortic aneurysms. This study was aimed at comparing the performance of computational fluid dynamics (CFD) and fluid–structure interaction (FSI) simulations against four-dimensional ...
