Redo Mitral Valve Replacement After Valve-in-Valve Transcatheter Mitral Valve Replacement. [PDF]

Cureus, 2023
The rising preference for percutaneous mitral valve-in-valve replacement (ViV TMVR) over redo surgical mitral valve replacement (MVR) is primarily due to its reduced bleeding risk. This report details a bloodless redo MVR performed for mitral stenosis post-ViV TMVR.

Mitral Valve Replacement for Bulky, Calcified Mitral Annulus: A Case Report [PDF]

Journal of Chest Surgery
Calcification of the mitral valve annulus is common in patients on dialysis. The growing number of individuals receiving dialysis has been accompanied by an increase in cases necessitating surgical intervention for mitral valve annulus calcification ...

Effect of concurrent mitral valve surgery for secondary mitral regurgitation upon mortality after aortic valve replacement or coronary artery bypass surgery

Frontiers in Cardiovascular Medicine, 2023
ObjectivesIt is uncertain whether concurrent mitral valve repair or replacement for moderate or greater secondary mitral regurgitation at the time of coronary artery bypass graft or aortic valve replacement surgery improves long-term survival ...

Advances in Transcatheter Electrosurgery for Treating Valvular Heart Disease

US Cardiology Review, 2021
Delivery of electrosurgery energy through catheters and guidewires enables interventionists to ‘cut’ through obstructive intravascular lesions or across cardiac chambers.

Treatment of More Than Moderate Ischemic Mitral Regurgitation in Patients Undergoing Left Ventricular Reconstruction

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

Left circumflex coronary artery injury following mitral valve replacement with late presentation: A case report and literature review [PDF]

Journal of Cardiovascular and Thoracic Research, 2022
Mitral valve replacement complications are more and more recognized due to the novel surgical techniques and the tendency to report such complications by young cardiologists and surgeons.

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

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
