SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

The Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Robotic mitral valve surgery after prior sternotomyCentral MessagePerspective

JTCVS Techniques, 2022
Objective: Despite the recent increase in the use of minimally invasive approaches to mitral valve surgery in patients with a prior sternotomy, the outcomes of the robotic approach to mitral valve surgery in this patient population have not been examined.

Coronary Flow in Hypertrophic Obstructive Cardiomyopathy—Immediate Effects of Alcohol Septal Ablation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Hypertrophic cardiomyopathy is associated with alterations in coronary microvascular function which have variable pathophysiologic mechanisms, and variable reversibility acutely and chronically following alcohol septal ablation (ASA).

Mitral valve operations at a high-volume pediatric heart center: Evolving techniques and improved survival with mitral valve repair versus replacement

Annals of Pediatric Cardiology, 2012
Mitral valve disease is quite variable and can occur as an isolated defect or in association with other complex left sided lesions. These lesions are often best described with detailed pre-operative imaging studies to define the valve anatomy and to ...

Transcatheter aortic valve replacement in a patient with previous mechanical mitral valve

IHJ Cardiovascular Case Reports, 2022
Transcatheter aortic valve implantation (TAVI) in post-MVR (mitral valve replacement) patients is a technical challenge due to the respective proximity of the aortic annulus and non-compliant prosthetic mitral valve ring.

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

Transapical transcatheter mitral valve implantation with J-valve in patients with degenerated mitral bioprostheses

BMC Cardiovascular Disorders, 2023
Background Due to the widespread application of bioprosthetic valve in the treatment of mitral valve disease in recent years, the incidence of valve failure has increased significantly, which is facing the need of reoperation.

Interventional Mitral Valve Edge‐to‐Edge Repair in Patients Above 85 Years of Age

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Mitral valve transcatheter‐edge‐to‐edge repair (M‐TEER) is routinely performed in patients with severe mitral regurgitation (MR) at high operative risk, frequently including elderly patients. Patients ≥ 85 years, however, are frequently excluded in clinical studies.

Mitral valve calcinosis as an important finding during heart examination [PDF]

Digital Diagnostics
BACKGROUND: Mitral valve calcinosis is a chronic degenerative process in the fibrous structures of the mitral valve. Advanced stages increase the risk of endocarditis and cardiac rhythm disturbances and contribute to cardiovascular mortality.
