Totally endoscopic mitral valve surgery: early experience in 188 patients

Journal of Cardiothoracic Surgery, 2021
Introduction Totally endoscopic technique has been widely used in cardiac surgery, and minimally invasive totally endoscopic mitral valve surgery has been developed as an alternative to median sternotomy for many patients with mitral valve disease.

Does isolated mitral annular calcification in the absence of mitral valve disease affect clinical outcomes after transcatheter aortic valve replacement? [PDF]

, 2020
AIMS  Mitral annular calcification (MAC) has been associated with adverse outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) but has been investigated in isolation of co-existent mitral regurgitation or mitral stenosis ...

Comparison Between the Acurate Neo and the Acurate Neo 2 Transcatheter Heart Valve System: Impact of Midframe Under‐Expansion

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) with the Acurate Neo has been linked to a significant incidence of paravalvular leakage (PVL), addressed by the Acurate Neo 2 incorporating an active sealing skirt. Recent findings suggest that midframe under‐expansion is associated with worse outcomes.

Percutaneous mitral valve commissurotomy

, 2019
Transcatheter therapies have progressively assumed a major role in the treatment of valve heart disease. The major drivers have been population ageing, the high prevalence of valve disease in the elderly, and the consequent need of less invasive ...

SURGICAL TREATMENT INDICATIONS IN ACQUIRED MITRAL VALVULAR DISEASES

Eurasian Journal of Medicine, 2019
Surgery of mitral valve is performed as closed or open mitral commissurotomy, mitral valve repair surgery and mitral valve replacement. The purpose of mitral valve surgery is to relieve the symptoms unresponsive to medical therapy, to improve the quality

Mechanisms of mitral valve development and disease

Frontiers in Cardiovascular Medicine
The mitral valve apparatus comprises the annulus, valve leaflets, chordae tendineae, and papillary muscles, forming an integrated biomechanical unit essential for unidirectional blood flow.

Image Segmentation for Mitral Regurgitation with Convolutional Neural Network Based on UNet, Resnet, Vnet, FractalNet and SegNet: A Preliminary Study

Big Data and Cognitive Computing, 2022
The heart’s mitral valve is the valve that separates the chambers of the heart between the left atrium and left ventricle. Heart valve disease is a fairly common heart disease, and one type of heart valve disease is mitral regurgitation, which is an ...

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Successful Percutaneous Retrieval of an Embolized MitraClip From the Right Subclavian Artery

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Single leaflet device attachment (SLDA) after mitral transcatheter valve edge‐to‐edge repair (M‐TEER) has been reported in up to 5% of patients. However, complete embolization of the M‐TEER device is exceedingly rare. Device retrievals in all previously reported cases were completed by vascular surgery cut down at the end. In this case, we are

Percutaneous Left Atrial Appendage Closure Using a PFO Occluder After an Incomplete Surgical Ligation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The case regards a 73‐year‐old male who was referred for consideration of percutaneous left atrial appendage closure. His left atrial appendage was ligated during prior mitral valve surgery, but was noted to be patent on a recent transesophageal echocardiography. An Amulet device was selected based on CT planning.
