SAGA GIS for Computing Multispectral Vegetation Indices by Landsat TM for Mapping Vegetation Greenness

open access: yesContemporary Agriculture, 2021
The study presents a comparative analysis of eight Vegetation Indices (VIs) used to examine vegetation greenness over the northern coasts of Iceland. The geographical extent of the study area is set by the coordinates of the two fjords, Eyjafjörður and ...

Revisiting tricuspid regurgitation: Historical insights and emerging research perspectives

open access: yesEuropean Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.
Tricuspid regurgitation (TR), once seen as benign, is now recognized as a serious and increasingly prevalent condition linked to aging and better imaging. Its association with greater morbidity and mortality has shifted clinical perspectives towards early diagnosis and intervention.

Transcatheter Tricuspid Valve Intervention in Patients With Previous Left Valve Surgery. [PDF]

open access: yes, 2021
BACKGROUND Scarce data exist on patients with previous left valve surgery (PLVS) undergoing transcatheter tricuspid valve intervention (TTVI). This study sought to investigate the procedural and early outcomes in patients with PLVS undergoing TTVI.

Transcatheter Tricuspid Valve Replacement in Patients After Prior Left‐Sided Valve Surgery: A Multicenter Retrospective Analysis

open access: yesJournal of Interventional Cardiology, Volume 2026, Issue 1, 2026.
Background Functional tricuspid regurgitation (TR) after previous left‐sided valve surgery (LSVS) represents a significant proportion of all isolated TR cases; tricuspid valve reoperation in such patients, often in the advanced stage of disease, is historically regarded as high‐risk.

Advances in transcatheter mitral and tricuspid therapies

open access: yesBMC Cardiovascular Disorders, 2020
Background While rheumatic mitral stenosis has been effectively treated percutaneously for more than 20 years, mitral and tricuspid regurgitation treatment appear as a contemporary unmet need.

Right ventricle to pulmonary artery coupling as a prognostic factor in tricuspid regurgitation: A systematic review

open access: yesESC Heart Failure, Volume 12, Issue 6, Page 4033-4040, December 2025.
The TAPSE/SPAP ratio is associated with worse prognosis in patients with significant tricuspid regurgitation and could indicate at‐risk patients. The exact cutoff value for RV‐PA uncoupling remains difficult to define and in available studies ranged from 0.26 to 0.49 mm/mmHg.

Relevance of residual tricuspid regurgitation for right ventricular reverse remodelling after tricuspid valve intervention in patients with severe tricuspid regurgitation and right‐sided heart failure

open access: yesEuropean Journal of Heart Failure, Volume 27, Issue 12, Page 3170-3179, December 2025.
Right ventricular reverse remodelling after transcatheter tricuspid valve intervention (TTVI). Optimal tricuspid regurgitation (TR) reduction is critical for right ventricular reverse remodelling. CMR, cardiac magnetic resonance; echo, echocardiography; RV EDV, right ventricular end‐diastolic volume. Abstract Aims Right ventricular reverse remodelling (

Transcatheter Management of Severe Paravalvular Leak in the Inferior Vena Cava Prosthesis of the TricValve Bicaval Valve System

open access: yesCatheterization and Cardiovascular Interventions, Volume 106, Issue 5, Page 2945-2948, November 1, 2025.
ABSTRACT We present a 74‐year‐old female with a history of mechanical aortic and mitral valve implantation and non‐Hodgkin lymphoma. She presented with right sided heart failure due to severe functional tricuspid regurgitation and was treated with transcatheter TricValve bicaval system implantation.

Management of patients with transvalvular right ventricular leads undergoing transcatheter tricuspid valve interventions: a scientific statement of the European Heart Rhythm Association and the European Association of Percutaneous Cardiovascular Interventions of the ESC endorsed by the Heart Rhythm Society, the Asian Pacific Heart Rhythm Society and the Canadian Heart Rhythm Society.

open access: yes
Up to one-third of patients referred for transcatheter tricuspid valve intervention (TTVI) have a transvalvular pacemaker (PPM) or implantable cardioverter-defibrillator (ICD) lead in place.

Transcatheter Tricuspid Valve Intervention Plus Optimized Medical Therapy Versus Optimized Medical Therapy Alone in Tricuspid Regurgitation: A Systematic Review and Meta-Analysis

open access: yesCardiovascular Innovations and Applications
Tricuspid regurgitation (TR) is common and associated with substantial morbidity and mortality. Although optimized medical therapy (OMT) can alleviate symptoms, it may be insufficient in severe cases, and surgical interventions carry considerable ...
