Characteristics, Trends, and Outcomes of Intravascular Lithotripsy-Assisted Transfemoral Transcatheter Aortic Valve Replacement in United States.

Background: Transfemoral (TF) access is the preferred approach for transcatheter aortic valve replacement (TAVR). Limited data exist regarding the outcomes of intravascular lithotripsy (IVL)-assisted TF TAVR in patients with peripheral artery disease.

Objectives: This study sought to examine contemporary characteristics, trends, and outcomes of IVL TAVR in the United States.

Utilization of a Novel Scoring System in Predicting 30-day Mortality in Acute Pulmonary Embolism, the CLOT-5 Pilot Study.

Objectives: To construct a new scoring system utilizing biomarkers, vitals, and imaging data to predict 30-day mortality in acute pulmonary embolism (PE).

Background: Acute PE, a well-known manifestation of venous thromboembolic disease, is responsible for over 100,000 deaths worldwide yearly. Contemporary management algorithms rely on a multidisciplinary approach to care via PE response teams (PERT) in the identification of low, intermediate, and high-risk patients.

Ultrasound-Assisted Versus Standard Catheter-Directed Thrombolysis for Acute Pulmonary Embolism: Insights From National Inpatient Sample.

Background: Pulmonary embolism is one of the leading causes of morbidity and mortality in the United States. Catheter-directed therapies have emerged as a promising treatment for managing intermediate- and high-risk patients; however, data comparing standard catheter-directed thrombolysis (SCDT) and ultrasound-assisted thrombolysis (USAT) are limited. This study aimed to investigate trends, outcomes, and predictors of mortality of both modalities from a nationally representative sample.

Trends and Outcomes of Interhospital Transfer for High-Risk Acute Pulmonary Embolism: A Nationwide Analysis.

Background: Data on outcomes of patients with high-risk acute pulmonary embolism (PE) transferred from other hospitals are scarce.

Methods: We queried the Nationwide Readmissions Database for admissions who were ≥18 years old, and with a primary discharge diagnosis of acute high-risk PE between the years 2016 and 2019. The main outcome of interest was the difference in all-cause in-hospital mortality between patients admitted directly to small/medium hospitals; patients admitted directly to large hospitals; and patients transferred to large hospitals.

Normal-Flow Low-Gradient Aortic Stenosis: Comparing the U.S. and European Guidelines.

Patients with normal-flow low-gradient (NFLG) severe aortic stenosis present both diagnostic and management challenges, with debate about the whether this represents true severe stenosis and the need for valve replacement. Studies exploring the natural history without intervention have shown similar outcomes of patients with NFLG severe aortic stenosis to those with moderate aortic stenosis and better outcomes after valve replacement than those with low-flow low-gradient severe aortic stenosis. Most studies (all observational) have shown that aortic valve replacement was associated with a survival benefit vs surveillance.

Mitral Valve Transcatheter Edge-to-Edge Repair After TAVR: A Nationwide Analysis.

Patients with persistent severe mitral regurgitation after transcatheter aortic valve replacement (TAVR) may benefit from mitral transcatheter edge-to-edge repair (M-TEER). Using the Nationwide Readmission Database, we identified patients who had M-TEER within 6 months after TAVR and compared their outcomes with patients who had M-TEER without previous recent TAVR during the same calendar year between 2014 and 2020. Because Nationwide Readmission Database data do not cross years, analysis was restricted to the last half of each calendar year.

Circumstances of Hospitalization Impact Outcomes of Pulmonary Embolism.

Clinical tools that stratify risk of acute pulmonary embolism (PE) are useful in guiding therapeutic decision making, although may neglect pragmatic and potentially impactful characteristics of hospitalization during care of venous thromboembolism (VTE). Using a retrospective cohort design, consecutive patients discharged after inpatient care for acute PE were retrospectively evaluated for features of hospitalization, including patient characteristics, treatment efficiency, and circumstances of hospitalization. A proportional hazards model incorporated nontraditional risk factors to assess their association with a primary composite endpoint of in-hospital bleeding or death after adjusting for conventional PE risk estimators, including the Pulmonary Artery Severity Index (PESI) and right ventricular/left ventricular (RV/LV) ratio.

Fibrinolytic Status and Risk of Death After Acute Pulmonary Embolism.

Background: Acute pulmonary embolism (PE) is a heterogeneous disease process with variable presentation and outcomes. The endogenous fibrinolytic system is a complex framework of regulatory pathways that maintains homeostasis by dissolving overabundant thrombi. We sought to investigate phenotypic profiles of the endogenous fibrinolytic system among patients presenting with acute PE and their impact on mortality.

Association between cancer, CHA2DS2VASc risk, and in-hospital ischaemic stroke in patients hospitalized for atrial fibrillation.

Background: Atrial fibrillation (AF) is commonly encountered in cancer patients. We investigated the CHA2DS2VASc score, and its association with in-hospital ischaemic stroke in patients with cancer who were hospitalized for AF.

Methods And Results: Using the United States National Inpatient Sample, all hospitalizations with principal diagnosis of AF between October 2015 and December 2018 were stratified by cancer diagnosis, type, and CHA2DS2VASc risk categories (low risk, low-moderate risk, moderate-high risk).

Trends in invasive treatment of patients hospitalized with aortic stenosis complicated by cardiogenic shock.

Background: Before the development of transcatheter aortic valve replacement (TAVR), balloon aortic valvuloplasty (BAV) was the only potential nonsurgical intervention for patients with aortic stenosis complicated by cardiogenic shock. Emergent TAVR is now an option and has shown acceptable outcomes compared with elective TAVR. We explored how treatment patterns for aortic stenosis and cardiogenic shock among patients received invasive intervention have shifted since TAVR was introduced.

In-hospital and Readmission Outcomes With Percutaneous Balloon Mitral Valvuloplasty.

Percutaneous balloon mitral valvuloplasty (PBMV) is primarily performed for rheumatic mitral stenosis (MS). Therefore, limited data exist on PBMV in countries with a low incidence of rheumatic disease. Using the Nationwide Readmission Database, we examined trends in in-hospital mortality and 30-day readmission among patients who received PBMV for rheumatic and non-rheumatic MS.

Patient characteristics and survival outcomes of cardiac arrest in the cardiac catheterization laboratory: Insights from get with the Guidelines®-Resuscitation registry.

Background: Characteristics and outcomes of patients with in-hospital cardiac arrest (IHCA) in the cardiac catheterization laboratory (CCL) have not been well-described. Thus, we compared the outcomes of patients with an IHCA in the CCL versus those in the intensive care unit (ICU) and operating rooms (OR).

Methods: Within the American Heart Association's Get With the Guidelines®-Resuscitation registry, we identified patients ≥ 18 years old with IHCA in the CCL, ICU, or OR between 2000-2019.
