HydroDynamic contrast Recanalization (HDR): Description of a new crossing technique for coronary chronic total occlusions.

Background: Intraplaque delivery of contrast has been utilized during percutaneous coronary interventions (PCI) of chronic total occlusions (CTO) to delineate anatomy and to facilitate wire crossing. Its utility as a tool to accomplish primary crossing of CTOs has not been described or validated.

Aims: We describe a new technique leveraging the diagnostic and therapeutic roles of intraplaque contrast injection to accomplish primary crossing of CTOs: HydroDynamic contrast Recanalization (HDR).

Midterm Outcomes of Patients With Complex Aortic Aneurysms Treated Using Mixed and Matched Endoprosthesis From Different Manufacturers.

Objectives: To evaluate outcomes of patients with complex aortic aneurysms (cAAs) undergoing fenestrated/branched endovascular aortic aneurysm repair (f/b-EVAR) using a combination of endoprostheses from different manufacturers.

Methods: The study is a 2-center retrospective analysis of prospectively maintained databases of patients with cAAs undergoing f/b-EVAR using a combination of endoprostheses from different manufacturers from 2013 to 2023. Primary endpoints included technical success, major adverse events and reintervention rates.

TRIVALVE Score: A Risk Score for Mortality/Hospitalization Prediction in Patients Undergoing Transcatheter Tricuspid Valve Intervention.

Background: Transcatheter tricuspid valve intervention (TTVI) has been increasingly adopted in recent years for the treatment of patients with tricuspid regurgitation (TR). However, no dedicated risk stratification has been established for patients undergoing TTVI.

Objectives: The aim of the present study was to propose a dedicated risk score for patients affected by severe TR undergoing TTVI.

Degenerative mitral stenosis by echocardiography: presentation and outcome.

Aims: Degenerative mitral stenosis (DMS) is due to degenerative mitral annular calcification (MAC) and valvular calcification. However, DMS impacts on the outcome, and therefore, potential treatment needs are poorly known. We aimed at evaluating survival after DMS diagnosis by Doppler echocardiography in routine practice.

Repolarization Injury and Occurrence of Torsades de Pointes During Acute Takotsubo Syndrome.

Background: During takotsubo syndrome (TS), QTc prolongation is common, reflecting repolarization injury and providing the substrate for torsades de pointes (TdP). TdP has been reported sporadically in TS, yet QTc prolongation and TdP risk are often overlooked during management.

Objectives: In TS patients, we sought to document TdP incidence, characteristics of patients with TdP, and association of QTc with postdischarge survival.

A Novel Echocardiographic Parameter to Confirm Low-Gradient Aortic Stenosis Severity.

Background: In patients with low-gradient (LG) aortic stenosis (AS), confirming disease severity and indication of intervention often requires dobutamine stress echocardiography (DSE) or aortic valve calcium scoring by computed tomography. We hypothesized that the mean transvalvular pressure gradient to effective orifice area ratio (MG/EOA, in mm Hg/cm) measured during rest echocardiography identifies true-severe AS (TSAS) and is associated with clinical outcomes in patients with low-flow, LG-AS.

Objectives: The purpose of this study was to evaluate the diagnostic and prognostic value of MG/EOA ratio.

Coronary Artery Calcium for Risk Stratification Among Persons With Very High HDL Cholesterol.

Background: Compared to normal high-density lipoprotein (HDL) cholesterol values, very high HDL cholesterol is associated with a higher incidence of mortality and atherosclerotic cardiovascular disease (ASCVD). As such, clinical risk stratification among persons with very high HDL cholesterol is challenging.

Objectives: Among persons with very high HDL cholesterol, the purpose was to determine the prevalence of coronary artery calcium (CAC) and compare the association between traditional risk factors vs CAC for all-cause mortality and ASCVD.

Pulsed Field Ablation to Treat Paroxysmal Atrial Fibrillation: Safety and Effectiveness in the AdmIRE Pivotal Trial.

Background: Evidence from clinical trials of early pulsed field ablation (PFA) systems in treating atrial fibrillation has demonstrated their promising potential to reduce complications associated with conventional thermal modalities while maintaining efficacy. However, the lack of a fully integrated mapping system, a staple technology of most modern electrophysiology procedures, poses limitations in lesion creation and workflow options. A novel variable-loop PFA catheter integrated with an electroanatomic mapping system has been developed that allows for real-time nonfluoroscopic procedural guidance and lesion indexing as well as feedback of tissue-to-catheter proximity.

Outcomes of patients with active cancer after transcatheter aortic valve replacement: an updated meta-analysis.

Background: Patients with active cancer and aortic stenosis may be under-referred for valve interventions due to concerns over a prohibitive risk. However, whether active cancer impacts outcomes after transcatheter aortic valve replacement (TAVR) remains unknown.

Methods: We searched PubMed, Embase, and Cochrane Library in December 2023 for studies comparing the post-TAVR outcomes of patients with versus without active cancer.

Percutaneous Edge-to-Edge Repair for Tricuspid Regurgitation: 3-Year Outcomes From the TRILUMINATE Study.

Background: Tricuspid regurgitation (TR) is a common valve disease that has a significant impact on patients' quality of life.

Objectives: This study sought to report the final 3-year outcomes of tricuspid transcatheter edge-to-edge repair (T-TEER) with the TriClip (Abbott) implant from the TRILUMINATE (TRILUMINATE Study With Abbott Transcatheter Clip Repair System in Patients With Moderate or Greater TR) study for the treatment of severe symptomatic TR.

Methods: The TRILUMINATE study (N = 98 subjects) is an international, prospective, single-arm, multicenter study to investigate the safety and performance of T-TEER with the TriClip implant in patients with symptomatic moderate or greater TR.

Benefit of isolated surgical valve repair or replacement for functional tricuspid regurgitation and long-term outcomes stratified by the TRI-SCORE.

Background And Aims: Severe tricuspid regurgitation is associated with increased mortality rates, but benefit of its correction and ideal timing are not clearly determined. This study aimed to identify patient subsets who might benefit from the surgery.

Methods: In TRIGISTRY, an international cohort study of consecutive patients with severe isolated functional tricuspid regurgitation (33 centres, 10 countries), survival rates up to 10 years were compared between patients who underwent isolated tricuspid valve surgery (repair or replacement) and those conservatively managed, overall and according to TRI-SCORE category (low: ≤3, intermediate: 4-5, and high: ≥6).
