Ticagrelor Paradox: Systematic Review and Network Meta-Analysis.

Background: Based on the landmark PLATO (Platelet Inhibition and Patient Outcomes) and TRITON-TIMI 38 (Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition With Prasugrel-Thrombolysis in Myocardial Infarction) trials, current guidelines recommend ticagrelor and prasugrel over clopidogrel for acute coronary syndrome. However, subsequent studies have failed to replicate the reported benefits of ticagrelor, raising concerns about the validity of the PLATO trial's findings.

Methods: Randomized trials published until January 2025 were searched on PubMed and Embase and included if they compared 2 of the 3 standard dual antiplatelet therapies: 12 months aspirin plus clopidogrel, prasugrel, or ticagrelor.

Vitamin K Antagonists Versus Direct Oral Anticoagulation After Transcatheter Mitral Valve Replacement.

Optimal anticoagulation strategies after transcatheter mitral valve replacement (TMVR) remain unknown with no randomized trial data. Current practices for anticoagulation after TMVR vary widely as a result. We aimed to compare clinical outcomes between vitamin K antagonists (VKA) and direct oral anticoagulation (DOAC) after transcatheter mitral valve replacement (TMVR) at our institution.

Transcatheter Versus Surgical Aortic Valve Replacement in Low-Risk Patients: Updated Meta-Analysis.

Long-term data are essential for selection between transcatheter (TAVR) and surgical (SAVR) aortic valve replacement in low-risk aortic stenosis (AS) patients. Given the recent randomized controlled trials (RCTs) and mid-term outcomes from existing trials, a reappraisal of the current literature is necessary. We systematically identified RCTs comparing TAVR and SAVR in low risk AS patients.

How to avoid transcatheter aortic valve replacement explant as the second valve procedure: image assessment for the index transcatheter aortic valve replacement.

The management of severe aortic stenosis (AS) has evolved significantly, with a shift toward shared decision-making regarding the choice of transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). This shift necessitates careful consideration of long-term valve durability, as both TAVR and SAVR with bioprosthetic valves offer limited durability, potentially requiring reoperation later in life. While mechanical valves and the Ross procedure offer lifelong durability, patient preferences, including avoidance of anticoagulation, often dominate the discussion.

Transapical Transcatheter Mitral Valve Replacement After Failed Transcatheter Edge-to-Edge Repair: A Multicenter Experience.

Background: Management of recurrent mitral regurgitation (MR) or relevant iatrogenic mitral valve (MV) stenosis after mitral transcatheter edge-to-edge repair (M-TEER) emerges as an increasingly relevant clinical issue. Surgery after M-TEER is associated with higher morbidity and mortality. Electrosurgical leaflet laceration and stabilization of the implant (ELASTA-Clip) followed by transcatheter mitral valve replacement (TMVR) is an innovative, less-invasive treatment option for patients with TEER failure.

Outcomes of Suction Debulking and Surgery in Patients With Isolated Tricuspid Valve Endocarditis.

Objective: Percutaneous vegetation debulking has been reported to treat tricuspid valve infective endocarditis (TVIE), but data on feasibility compared with conventional surgical strategies are limited. We aimed to compare short-term outcomes of suction debulking with partial venovenous bypass to conventional open surgery in this population.

Methods: This was a single-center, retrospective study that included all patients with isolated TVIE who underwent suction debulking with partial venovenous bypass or tricuspid valve surgery between January 2010 and December 2022.

Valvular Heart Disease-Related Mortality Between Middle- and High-Income Countries During 2000 to 2019.

Transcatheter Myotomy to Reduce Left Ventricular Outflow Obstruction.

Background: Left ventricular outflow tract (LVOT) obstruction is a source of morbidity in hypertrophic cardiomyopathy (HCM) and a life-threatening complication of transcatheter mitral valve replacement (TMVR) and transcatheter aortic valve replacement (TAVR). Available surgical and transcatheter approaches are limited by high surgical risk, unsuitable septal perforators, and heart block requiring permanent pacemakers.

Objectives: The authors report the initial experience of a novel transcatheter electrosurgical procedure developed to mimic surgical myotomy.

Left Ventricular Outflow Tract Modification for Transcatheter Mitral Valve Replacement.

Left ventricular outflow tract (LVOT) obstruction is a life-threatening complication of transcatheter mitral valve replacement. In-depth analysis of pre-procedural computed tomography enables accurate prediction of this risk. Several techniques for LVOT modification, including Laceration of the Anterior Mitral leaflet to Prevent Outflow ObtructioN, preemptive alcohol septal ablation, preemptive radiofrequency ablation, and Septal Scoring Along the Midline Endocardium, have been described as effective strategies to mitigate this risk.
