Impact of Atrial Fibrillation Type on Outcomes of Transcatheter Aortic Valve Replacement for Aortic Stenosis: A Single-Center Analysis.

Background: Atrial fibrillation (AF) is a recognized risk factor for mortality after transcatheter aortic valve replacement for severe aortic stenosis, but the impact of different types of AF on clinical outcomes remains unclear.

Methods: This retrospective study included 982 patients divided into 3 groups: no AF, paroxysmal AF, and nonparoxysmal AF (persistent or permanent). Clinical outcomes were analyzed using inverse probability weighting and multivariate models.

Impact of prior coronary artery bypass grafting and coronary lesion complexity on outcomes of transcatheter aortic valve replacement for severe aortic stenosis.

Objective: To investigate the impact of prior coronary artery bypass grafting (CABG) and coronary lesion complexity on transcatheter aortic valve replacement (TAVR) outcomes for aortic stenosis.

Methods: Clinical outcomes of TAVR were retrospectively compared between patients with and without prior CABG, and between patients with prior CABG and without coronary artery disease (CAD). The impact of the CABG SYNTAX score was also evaluated in patients with prior CABG.

Impact of coronary artery disease and revascularization on outcomes of transcatheter aortic valve replacement for severe aortic stenosis.

Background/purpose: To evaluate the impact of coronary artery disease (CAD), percutaneous coronary intervention (PCI), and coronary lesion complexity on outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis.

Methods/materials: This retrospective study included 1042 patients divided into two groups by the presence or absence of CAD (SYNTAX score 0, no history of revascularization). Propensity score matching was used to compare the two groups.

Impact of mitral stenosis on early and late outcomes of transcatheter aortic valve replacement for aortic stenosis: a single-center analysis.

Objectives: To assess the impact of concomitant mitral stenosis (MS) on early and late outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis.

Methods: This study involved 952 patients undergoing TAVR for severe tricuspid aortic stenosis. The patients were classified into 3 groups: without MS, with progressive MS, and severe MS (mitral valve area ≤ 1.

Clinical and Echocardiographic Outcomes of Patients Undergoing Transcatheter Edge-to-Edge Repair for Functional vs Degenerative Mitral Valve Regurgitation.

To analyze clinical and echocardiographic outcomes after transcatheter edge-to-edge repair (TEER) with mitral valve clip device (MitraClip-TM) for functional vs degenerative mitral valve regurgitation (MR). All consecutive 185 patients undergoing TEER between January 2019 and March 2023 were included in the study. A propensity-adjusted analysis investigated differences among functional vs degenerative MR mechanism groups.

1-Year Outcomes of Transcatheter Tricuspid Valve Repair.

Background: Surgical management of isolated tricuspid regurgitation (TR) is associated with high morbidity and mortality, thereby creating a significant need for a lower-risk transcatheter solution.

Objectives: The single-arm, multicenter, prospective CLASP TR (Edwards PASCAL TrAnScatheter Valve RePair System in Tricuspid Regurgitation [CLASP TR] Early Feasibility Study) evaluated 1-year outcomes of the PASCAL transcatheter valve repair system (Edwards Lifesciences) to treat TR.

Methods: Study inclusion required a previous diagnosis of severe or greater TR and persistent symptoms despite medical treatment.

Computed tomography-derived membranous septum length as predictor of conduction abnormalities and permanent pacemaker implantation after TAVI: A meta-analysis of observational studies.

Background: Permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI) is associated with higher risk of mortality and rehospitalization for heart failure. Efforts to prevent conduction abnormalities (CA) requiring PPI after TAVI should be made. The membranous septum (MS) length and its interaction with implantation depth (ID-ΔMSID) could provide useful information about the risk of CA/PPI following TAVI.

1-Year Outcomes of Cardioband Tricuspid Valve Reconstruction System Early Feasibility Study.

Background: Tricuspid regurgitation (TR) is prevalent and undertreated, with mortality and morbidity increasing with TR severity. Given poor outcomes with medical therapy and high in-hospital mortality for isolated tricuspid valve surgery, emerging transcatheter repair devices offer a promising alternative.

Objectives: The Edwards Cardioband Tricuspid Valve Reconstruction System Early Feasibility study (NCT03382457) evaluates the treatment of functional TR via annular reduction with the Cardioband Tricuspid Valve Reconstruction System (Edwards Lifesciences).

Pulmonary Embolus Imaging Assessment With Emphasis on Echocardiography.

Background: This case discusses the importance of echocardiography, or transthoracic echocardiography (TTE), in detecting and diagnosing pulmonary embolisms (PE). The patient described in this case study, who underwent an echocardiography examination a few years before, had little reason to suspect the result of his PE would be a metastatic tumor showering masses of cancerous material and blood clots to his lungs.

Discussion: Although computed tomography angiography is the gold standard for diagnosing PE, echocardiography is the preferred modality for identifying heart masses or tumors and provides vital PE information.

Early Feasibility Study of Cardioband Tricuspid System for Functional Tricuspid Regurgitation: 30-Day Outcomes.

Objectives: The study reports for the first time the 30-day outcomes of the first U.S. study with the Cardioband tricuspid valve reconstruction system for the treatment of functional tricuspid regurgitation (TR).

Large obstructive cardiac myxofibrosarcoma is nearly invisible on transthoracic echocardiogram.

Malignant primary cardiac tumors are exceptionally rare, and the most common of these are sarcomas. We present a case of a patient who was found to have a large mass in the left atrium causing obstruction of mitral inflow. Only selected views on a transthoracic echocardiogram reveal the mass and its hemodynamic effect.
