  • - The Aveir DR system is a new type of dual-chamber leadless pacemaker that features separate atrial and ventricular components capable of communicating wirelessly for synchronized heart pacing.
  • - A study involving 399 patients showed that the success rates of implant-to-implant (i2i) communication between the atrial and ventricular pacemakers exceeded 90% at all tested intervals over six months.
  • - Improvements in communication success were noted, particularly for patients with initial lower success rates, suggesting benefits from reprogramming and device stabilization over time.

Perioperative considerations in anesthesia for minimally invasive repair of pectus excavatum, Nuss procedure.

Semin Pediatr Surg

October 2024

Clinical Professor of Anesthesiology and Child Health, University of Arizona, School of Medicine, Phoenix. Department of Pediatric Anesthesiology, Phoenix Children's Hospital, 1919 E Thomas Road, Phoenix, AZ 85016, USA. Electronic address:

Pectus excavatum (PE) is a common anterior chest wall deformity that affects the heart and lungs depending on the severity of compression. The Nuss procedure, a minimally invasive repair of pectus excavatum, has evolved over the years with thoracoscopic assistance and minimal incision. Despite improved surgical techniques, pain and nausea are often the most common factors determining hospital length of stay.

Infants with dextro-transposition of the great arteries (d-TGA) are at high risk for hemodynamic compromise in the immediate postnatal period due to dependence on intracardiac mixing for oxygen delivery. This period of profound hypoxemia may have long-term implications, as previous studies demonstrated patients with d-TGA are at increased risk for neurocognitive delays despite effective surgical correction in the neonatal period. Balloon atrial septostomy (BAS) is an established intervention that improves intracardiac mixing and perioperative hemodynamics.

Article Synopsis
  • The study looked at whether a medical procedure called thrombectomy helps patients who have a large stroke as seen on a specific type of scan called a noncontrast CT within 24 hours of having the stroke.
  • It involved 300 patients from different hospitals who were split into two groups; one group received the thrombectomy treatment, while the other only received regular care.
  • The main goal was to see if those who had thrombectomy had better recovery after 90 days compared to those who didn’t, along with checking if there were any serious side effects.

Objectives: The delta shock index (ΔSI), defined as the change in shock index (SI) over time, is associated with hospital morbidity and mortality, but prehospital studies about ΔSI are limited. We investigate the association of prehospital ΔSI with mortality and resource utilization, hypothesizing that increases in SI among field trauma patients are associated with increased mortality and blood product transfusion.

Methods: We performed a multicenter, retrospective, observational study from the Linking Investigators in Trauma and Emergency Services (LITES) network.

Article Synopsis
  • The study examines how frailty and delirium affect in-hospital mortality and discharge outcomes for older adults hospitalized due to acute decompensated heart failure (ADHF).
  • Data from over 3.5 million hospitalizations showed that both conditions significantly increase the risk of death and the likelihood of a non-home discharge.
  • The most severe outcomes were observed in patients experiencing both high frailty and delirium, indicating a need for greater awareness and intervention strategies for these vulnerable patients.

Background: Cardiac resynchronization therapy (CRT) is a guideline-recommended therapy in patients with heart failure with mildly reduced ejection fraction (HFmrEF, 36%-50%) and left bundle branch block or indication for ventricular pacing. Conduction system pacing (CSP) using left bundle branch area pacing or His bundle pacing has been shown to be a safe and physiologic alternative to biventricular pacing (BVP).

Objective: The aim of this study was to compare the clinical outcomes between BVP and CSP for patients with HFmrEF undergoing CRT.

Objective: Several observational studies have demonstrated an association between diabetes mellitus (DM) and above-ankle amputation after lower extremity revascularization (LER). However, data from prospective randomized trials is lacking. This analysis compares the outcomes of patients with and without DM enrolled in the Best Endovascular vs Best Surgical Therapy in patients with Chronic Limb-Threatening Ischemia (BEST-CLI) trial.

Post-COVID changes and disparities in cardiovascular mortality rates in the United States.

Prev Med Rep

October 2024

Keele Cardiovascular Research Group, Centre for Prognosis Research, Keele University, Stoke-on-Trent, UK.

Introduction: The COVID-19 pandemic disrupted healthcare delivery and increased cardiovascular morbidity and mortality. This study assesses whether cardiovascular mortality rates in the US have recovered post-pandemic and examines the equity of this recovery across different populations.

Methods: We analyzed data from the CDC WONDER database, covering US residents' mortality from 2018-2023.

Hypertension is one of the leading risk factors for cardiovascular disease. The ACC/AHA/Multisociety hypertension guideline covered all aspects of the recommendations for optimal blood pressure diagnosis and management to improve cardiovascular outcomes. Despite this, there remains a growing prevalence of hypertension within the United States, largely in non-Hispanic Black women at earlier stages of their life course.

  • Researchers studied strokes from 1990 to 2021 to understand how many people get them and how they are affected around the world.
  • In 2021, strokes caused about 7.3 million deaths and were a major cause of health problems, especially in specific regions like Southeast Asia and Oceania.
  • There are differences in stroke risks based on where people live and their age, and some areas actually saw more strokes happening since 2015.

Article Synopsis
  • This study examines the effectiveness and safety of pulsed field ablation (PFA) for treating atrioventricular nodal reentrant tachycardia (AVNRT), focusing on its impact on dual-pathway electrophysiology.
  • All 40 patients achieved acute success with PFA, showing an average total ablation time of 7.9 seconds, and 80% experienced induced slow junctional rhythm; however, there were instances of transient atrioventricular block in 17.5% of patients.
  • The study concludes that while PFA is highly effective for slow pathway modification, there are risks of transient AV block, especially when performed close to the His bundle,

Division of Trauma, Critical Care, Burns, and Emergency Surgery, Department of Surgery, College of Medicine, University of Arizona, Tucson, Arizona. Electronic address:

Article Synopsis
  • The study compares outcomes of hemodynamically stable trauma patients who underwent diagnostic laparoscopy (DL) versus nontherapeutic laparotomy (NL) over four years (2017-2020).
  • Data from 3801 patients were analyzed, revealing that those who had DL experienced significantly lower odds of mortality and major complications, alongside shorter hospital stays.
  • The findings suggest that DL is a more effective and safer option for stable trauma patients, reducing the need for unnecessary exploratory surgeries.

Leiomodin 2 neonatal dilated cardiomyopathy mutation results in altered actin gene signatures and cardiomyocyte dysfunction.

NPJ Regen Med

September 2024

Department of Cellular and Molecular Medicine and Sarver Molecular Cardiovascular Research Program, University of Arizona, Tucson, AZ, 85724, USA.

Neonatal dilated cardiomyopathy (DCM) is a poorly understood muscular disease of the heart. Several homozygous biallelic variants in LMOD2, the gene encoding the actin-binding protein Leiomodin 2, have been identified to result in severe DCM. Collectively, LMOD2-related cardiomyopathies present with cardiac dilation and decreased heart contractility, often resulting in neonatal death.

Contemporary studies of rheumatic heart disease (RHD) within American Indian communities are lacking, despite recent work indicating high rates of group A streptococcus, the precursor to RHD. Utilizing retrospective chart review of the Indian Health Service, we sought to characterize the burden of acute rheumatic fever and RHD within an American Indian tribe in Eastern Arizona. Our study found that, in line with other high-income countries, RHD in the US continues to disproportionately impact native peoples, with rates 10 times that of the general population.
