The functional limits of the aneurysmal aortic root. A unique pressure testing apparatus

Journal of Cardiothoracic Surgery, 2020
Background The aortic root has unique embryological development and is a highly sophisticated and complex structure. In studies that report on the biomechanical characteristics of the thoracic aorta, distinction between the aortic root and ascending ...

Aortic Valve Repair and Early-Career Surgeons—Nothing Is Impossible

Journal of Cardiovascular Development and Disease, 2023
Aortic valve repair with either the reimplantation of the aortic valve or aortic root remodelling with the external annuloplasty procedure is the most effective means of treating aortic regurgitation and/or aortic root aneurysms [...]

Aortic root ring sign: multimodality imaging of aortic root abscess [PDF]

QJM, 2015
Learning point for clinicians Accurate diagnosis of culture-negative infective endocarditis with aortic root abscess is difficult but important, as the patients may benefit from early antibiotics and early surgical treatment. Multimodality imaging and the remarkable ring-like imaging appearance should complement echocardiography and allow further ...

Managing Thoracic Aortic Aneurysm in Patients with Bicuspid Aortic Valve Based on Aortic Root-Involvement

Frontiers in Physiology, 2017
Bicuspid aortic valve (BAV) can be both sporadic and hereditary, is phenotypically variable, and genetically heterogeneous. The clinical presentation of BAV is diverse and commonly associated with a high prevalence of valvular dysfunction producing ...

Association of sleep apnoea risk and aortic enlargement in Marfan syndrome

BMJ Open Respiratory Research, 2021
Background Marfan syndrome (MFS) is a connective tissue disorder characterised by complex aortic pathology and a high prevalence of obstructive sleep apnoea (OSA). OSA produces intrathoracic transmural stresses that may accelerate aortic injury.

Valve-sparing aortic root replacement and aortic valve repair in a patient with acromegaly and aortic root dilatation

Russian Open Medical Journal, 2015
Aortic regurgitation and dilatation of the aortic root and ascending aorta are severe complications of acromegaly. The current trend for management of an aortic root aneurysm is valve-sparing root replacement as well as restoring the diameter of the ...

Bicuspid Aortic Insufficiency With Aortic Root Aneurysm: Root Reimplantation Versus Bentall Root Replacement [PDF]

The Annals of Thoracic Surgery, 2016
In patients with a bicuspid aortic valve presenting with aortic insufficiency (AI) and root aneurysm, we assessed whether outcomes with primary cusp repair with root reimplantation were equivalent to the gold standard Bentall procedures.From 2002 to 2014, 710 patients with bicuspid aortic valve underwent aortic root procedures.

The susceptibility of the aortic root: porcine aortic rupture testing under cardiopulmonary bypass

Journal of Cardiothoracic Surgery, 2021
Background In our earlier study on the functional limits of the aneurysmal aortic root we determined the pig root is susceptible to failure at high aortic pressures levels.
