Percutaneous technique for creation of tricuspid regurgitation in an ovine model

, 2007
Experimental models of tricuspid regurgitation (TR) are needed to study the percutaneous placement of prosthetic atrioventricular valves. The purpose of this study was to develop an appropriate simple and reproducible percutaneous experimental model for ...

Transcatheter therapies for tricuspid valve regurgitation

, 2020
: Tricuspid regurgitation, either isolated or associated with left-valve disease, has a strong impact on outcome. Surgical treatment of tricuspid regurgitation has increased in recent years, but in-hospital mortality remains high probably due to the risk

KLF5 Downregulation Links Impaired BNIP3‐Mediated Mitophagy to Inflammatory Valve Remodeling in Calcific Aortic Valve Disease

Advanced Science, EarlyView.
In human CAVD, KLF5 is reduced in VIC‐rich regions and remodeling/stress‐associated VIC states. In VICs, KLF5 sustains BNIP3 promoter activity and BNIP3‐mediated mitophagy, thereby limiting cytosolic mtDNA accumulation. KLF5 loss weakens mitochondrial quality control and enhances mtDNA‐sensitive STING/NF‐κB/NLRP3 inflammatory signaling under osteogenic

Clinical efficacy of two different tricuspid annuloplasty techniques in left cardiac valve surgery

Asian Pacific Journal of Tropical Medicine, 2018
Objective: To investigate the mid-and long-term clinical effects of tricuspid valvuloplasty with the implantation of an artificial plastic ring. Methods: Data of 677 patients who had functional tricuspid regurgitation and left cardiac valve disease and ...

Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...

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.

Physiological and clinical consequences of relief of right ventricular outflow tract obstruction late after repair of congenital heart defects. [PDF]

, 2006
BACKGROUND: Right ventricular outflow tract obstruction (RVOTO) is a common problem after repair of congenital heart disease. Percutaneous pulmonary valve implantation (PPVI) can treat this condition without consequent pulmonary regurgitation or ...

Valve reconstruction or replacement for long-term biopsy-induced tricuspid regurgitation following heart transplantation

, 1996
Tricuspid regurgitation following heart transplantation can become a severe problem in a subset of patients, where medical therapy fails. Operative findings are described and results of subsequent results with surgical intervention including repair and ...

Early Experience With Evoque Transcatheter Tricuspid Valve Replacement in Carcinoid Heart Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Tricuspid regurgitation (TR) is nearly universal in carcinoid heart disease (CHD), but surgical replacement carries significant risk, and CHD was excluded from the landmark TRISCEND II trial. We present seven patients with CHD undergoing Evoque transcatheter tricuspid valve replacement (TTVR) at two tertiary centers.
