Cardiology Discovery, 2023 Objective:. While evidence-based clinical guidelines recommend chordal-sparing mitral valve replacement, rather than mitral valve repair, in patients with severe ischemic mitral regurgitation (IMR) undergoing coronary artery bypass grafting, there are no

Estimation of mitral valve hinge point coordinates -- deep neural net for echocardiogram segmentation [PDF]
Computer Science Research Notes , CSRN 3201, 2022, ISSN 2464-4617, 2023 Cardiac image segmentation is a powerful tool in regard to diagnostics and treatment of cardiovascular diseases. Purely feature-based detection of anatomical structures like the mitral valve is a laborious task due to specifically required feature engineering and is especially challenging in echocardiograms, because of their inherently low contrast and

Mitral valve replacement in infants and children 5 years of age or younger: Evolution in practice and outcome over three decades with a focus on supra-annular prosthesis implantation [PDF]
, 2008 ObjectiveSuccessful mitral valve replacement in young children is limited by the lack of small prosthetic valves. Supra-annular prosthesis implantation can facilitate mitral valve replacement with a larger prosthesis in children with a small annulus, but

Homograft Replacement of the Mitral Valve [PDF]
Circulation, 1968 Replacement of the mitral valve with an aortic valve homograft has become feasible. Clinical and hemodynamic assessments of eight patients who received the new homograft were made from 3 to 6 months following surgery. Marked improvement was reported by six patients and mild to moderate improvement by two.

Machine Learning for Automated Mitral Regurgitation Detection from Cardiac Imaging [PDF]
In: Medical Image Computing and Computer Assisted Intervention -
MICCAI 2023. pp. 236-246 (2023), 2023 Mitral regurgitation (MR) is a heart valve disease with potentially fatal consequences that can only be forestalled through timely diagnosis and treatment. Traditional diagnosis methods are expensive, labor-intensive and require clinical expertise, posing a barrier to screening for MR. To overcome this impediment, we propose a new semi-supervised model

Double cardiac pseudoaneurysm in a postoperative patient
Türk Kardiyoloji Derneği Arşivi, 2015 A mitral-aortic intervalvular fibrosa pseudoaneurysm is a rare complication after aortic and mitral valve replacement and aortic root replacement. A left ventricular pseudoaneurysm after mitral valve replacement is also a rare complication.

Computational analysis of flow structures in turbulent ventricular blood flow associated with mitral valve intervention [PDF]
Frontiers in Physiology (2022) 752, 2021 Cardiac disease and clinical intervention may both lead to an increased risk for thrombosis events due to modified blood flow in the heart, and thereby a change in the mechanical stimuli of blood cells passing through the chambers of the heart. Specifically, the degree of platelet activation is influenced by the level and type of mechanical stresses in
