TTVI: A Two-Tier Vector Index for Low-WAL Approximate Nearest Neighbor Search in Databases

IEEE Access
Vector similarity search in relational databases underpins retrieval-augmented generation and semantic search, but indexes like HNSW and IVFFlat in pgvector produce high write-ahead log (WAL) volume because every insert touches many index pages.

Beyond the Left Ventricle: Modern Echocardiographic Assessment of Right Ventricular Function in Tricuspid Regurgitation [PDF]

Cardiovascular Ultrasound
Background The right ventricle (RV) and tricuspid valve (TV) have historically been neglected in cardiovascular research and clinical practice. However, growing evidence has established RV dysfunction and tricuspid regurgitation (TR) as independent ...

“Guidelines Recommendations on the Treatment of Tricuspid Regurgitation. Where Are We and Where Do We Go With Transcatheter Valve Intervention”

Frontiers in Cardiovascular Medicine, 2018
Tricuspid regurgitation (TR) is an important clinical problem because it is frequent and carries a poor prognosis when it is left uncorrected. However, there is still a lack of awareness of tricuspid disease in the medical community.

Persistent Severe Tricuspid Regurgitation After Mitral Transcatheter Edge-to-Edge Repair: Prognostic Implications of Guideline-Based Eligibility for Transcatheter Tricuspid Valve Intervention [PDF]

Structural Heart
Background: Persistent tricuspid regurgitation (TR) after mitral transcatheter edge-to-edge repair (M-TEER) is common and associated with adverse outcomes.

The Impact of Preexisting Cardiac Implantable Electronic Devices on the Safety of Transcatheter Tricuspid Valve Interventions: A Systematic Review and Meta-Analysis [PDF]

Journal of Cardiovascular Development and Disease
Background: Tricuspid regurgitation (TR) increases mortality but remains undertreated due to high surgical risks. Transcatheter tricuspid valve interventions (TTVI) offer safer alternatives, improving functional status and quality of life.

Screening and Qualification for Transcatheter Tricuspid Valve Interventions—Preliminary Findings from the CAPTURE Pilot Study [PDF]

Life
Background: Transcatheter tricuspid edge-to-edge repair (T-TEER) is the most widely used treatment option for patients with tricuspid regurgitation (TR). In real-world practice, a substantial proportion of referred patients are not eligible for T-TEER or

Prognostic Performance of a Modified TRI-SCORE Incorporating RV–PA Uncoupling After Transcatheter Tricuspid Valve Interventions [PDF]

Journal of Cardiovascular Development and Disease
Background: The TRI-SCORE was developed to predict mortality after tricuspid valve surgery and has demonstrated prognostic value in patients undergoing transcatheter tricuspid valve interventions (TTVI).

Temporal Trends in Transcatheter Tricuspid Valve Interventions After FDA Approval in the United States [PDF]

JACC: Advances
Background: Transcatheter tricuspid valve interventions (TTVIs) have recently received commercial approval; however, contemporary adoption trends in early postapproval phase are not well described.

Transcatheter tricuspid valve intervention versus optimal medical therapy alone for severe tricuspid regurgitation: an updated meta-analysis with reconstructed time-to-event data [PDF]

International Journal of Cardiology: Heart & Vasculature
Background: Severe tricuspid regurgitation (TR) is strongly associated with high mortality and morbidity. This meta-analysis aims to compare the outcomes of transcatheter tricuspid valve intervention (TTVI) versus optimal medical treatment (OMT) alone ...
