Combined left atrial appendage occlusion and catheter ablation procedure for left atrial arrhythmias: A real-world, propensity-matched analysis.

Introduction: Real-world studies comparing safety and efficacy of combined percutaneous left atrial appendage occlusion (LAAO) and catheter ablation (CA) to LAAO alone are limited.

Methods: Patients from a large US hospital system undergoing combined LAAO and left-atrial CA from 8/2020 to 2/2024 were retrospectively analyzed and compared to a control group undergoing LAAO alone. Controls were identified using a 1:2 propensity score match based on LAAO device type (Watchman FLX vs.

Readmission-related outcomes of surgical versus transcatheter aortic valve replacement in patients aged 65 or older with bicuspid aortic valve.

Background: There continues to be debate regarding the superiority of transcatheter (TAVR) over surgical aortic valve replacement (SAVR) in patients with bicuspid aortic valves (BAV). We aimed to compare outcomes during readmissions in elderly patients with BAV who underwent SAVR or TAVR.

Methods: Patients 65 years or older with BAV who underwent TAVR or isolated SAVR were identified using the National Readmission Database from 2012 through 2018.

Acute Coronary Syndrome After Transcatheter Aortic Valve Implantation (Results from Over 40,000 Patients).

Acute coronary syndrome (ACS) encompasses a broad category of presentations from unstable angina to ST-elevation myocardial infarctions. Most patients undergo coronary angiography upon presentation for diagnosis and treatment. However, the ACS management strategy after transcatheter aortic valve implantation (TAVI) may be complicated because of challenging coronary access.

Readmission with infective endocarditis within 90 days following transcatheter aortic valve implantation.

Introduction: Transcatheter aortic valve implantation (TAVI) continues to be the most common modality of treating aortic stenosis in the United States. While infective endocarditis (IE) and its outcomes have been well documented after surgical aortic valve replacement, the incidence and outcomes of early IE after TAVI have not been well described.

Methods: All patients who underwent TAVI from 2012 through 2018 were identified using the National Readmission Database.

Current Status of Transcatheter Tricuspid Valve Therapies.

Tricuspid regurgitation is a complex disease that carries a poor prognosis, and surgical repair is associated with high mortality. In light of the success of other transcatheter-based valve interventions, transcatheter tricuspid therapy has recently seen exponential use both clinically and in innovation. Given the rapid development of many tricuspid systems and multiple on-going clinical trials, the aim of this review is to highlight the current state of transcatheter tricuspid therapeutics and to provide an up-to-date view of their clinical use, outcomes and future directions.

Outcomes of Surgical Aortic Valve Replacement After Transcatheter Aortic Valve Implantation.

Few studies have reported their experience in explantation of a transcatheter heart valve. We found 2,100 patients who underwent transcatheter aortic valve implantation (TAVI) from 2013 through 2021. Of 2,100, a total of 17 patients underwent surgical aortic valve replacement after TAVI, including surgical bailout.

Long-term Outcomes of Percutaneous Coronary Intervention in Patients with Prior Coronary Artery Bypass Grafting.

BACKGROUND Patients with a prior coronary artery bypass graft (CABG) may have a need for repeat revascularization, which is typically attempted first via percutaneous coronary intervention (PCI) of either a bypass graft or native vessel. Long-term outcomes of native vessel compared to graft PCI after CABG have not yet been explored in a large institution study. METHODS Patients with history of prior CABG who underwent PCI at our institution during 2010-2018 were included.

Impact of Combined Pre and Postcapillary Pulmonary Hypertension on Survival after Transcatheter Aortic Valve Implantation.

We aimed to evaluate the association between pulmonary hypertension (PH) hemodynamic classification and all-cause mortality in patients with symptomatic severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). PH is common and associated with post-TAVI outcomes in patients with severe AS. Although PH in these patients is primarily driven by elevated left-sided pressures (postcapillary PH), some patients develop increased pulmonary vascular resistance (PVR) configuring the combined pre- and postcapillary PH (CpcPH).

Pulmonary vascular resistance determines mortality in end-stage renal disease patients with pulmonary hypertension.

The multifactorial etiology of pulmonary hypertension (PH) in end-stage renal disease (ESRD) includes patients with and without elevated pulmonary vascular resistance (PVR). We explored the prognostic implication of this distinction by evaluating pretransplant ESRD patients who underwent right heart catheterization and echocardiography. Demographics, clinical data, and test results were analyzed.

Outcomes of persistent pulmonary hypertension following transcatheter aortic valve replacement.

Objectives: To determine the prevalence and factors associated with persistent pulmonary hypertension (PH) following transcatheter aortic valve replacement (TAVR) and its relationship with long-term mortality.

Methods: Consecutive patients who underwent TAVR from July 2011 through January 2016 were studied. The prevalence of baseline PH (mean pulmonary artery pressure ≥25 mm Hg on right heart catheterisation) and the prevalence and the predictors of persistent≥moderate PH (pulmonary artery systolic pressure (PASP)>45 mm Hg on 1 month post-TAVR transthoracic Doppler echocardiography) were collected.

Relationship between silent myocardial ischemia and coronary artery disease risk factors.

Background: The association between silent myocardial ischemia (SMI) and coronary artery disease (CAD) risk factors in asymptomatic patients with no prior history of CAD referred for stress myocardial perfusion imaging (MPI) is unknown.

Methods: We retrospectively evaluated patients who underwent MPI over a 3.4-year period to identify those who did not have chest pain, dyspnea, or known CAD.

Effect of alcohol septal ablation in patients with hypertrophic cardiomyopathy on left-ventricular mechanical dyssynchrony as assessed by phase analysis of gated SPECT myocardial perfusion imaging.

Patients with hypertrophic cardiomyopathy (HCM) may have delayed septal activation and left ventricular (LV) mechanical dyssynchrony, and may improve after alcohol septal ablation (ASA). This study used phase analysis of gated SPECT myocardial perfusion imaging (MPI) to evaluate septal activation and LV dyssynchrony in HCM patients pre- and post-ASA. Phase analysis was applied to 28 controls, and 32 HCM patients having rest MPI pre- and post-ASA to assess septal-lateral mechanical activation delay (SLD) and consequent LV dyssynchrony.

Detection of elevated right atrial pressure using a simple bedside ultrasound measure.

Aims: Accurate assessment of right atrial pressure (RAP) often requires invasive measurement. With normal RAP, Valsalva increases right internal jugular vein (RIJV) cross sectional area (CSA) 20% to 30%. With high RAP, when venous compliance is low, we hypothesized that the increase in CSA would be blunted and could be detected non-invasively with bedside ultrasound.
