Introduction: The heart team approach is now the standard of care for patients with complex coronary artery disease; however, the definition of a heart team is variable. We embarked on a project to create an extended, multidisciplinary heart team to evaluate patients we deemed high risk for coronary revascularization. In doing so, we created a new service, workflow, and paradigm.

A congenitally malformed aortic valve, unicuspid (UAV), or bicuspid (BAV), occurs in about 1% of the population and is known to be more frequent in patients with aortic dissection. The clinical and operative findings in a series of 134 patients with spontaneous, acute type A aortic dissection were studied, comparing patients with normal and abnormal aortic valve morphology. The aortic valve was normal in 123 of 134 (92%) patients and abnormal in 11 of 134 (8%) patients: BAV in 10 of 134 (7.

Background: Cardiothoracic surgery lacks gender and racial/ethnic diversity. Recent studies have highlighted disparities based on gender and race/ethnicity among academic cardiothoracic surgeons. The impact of the intersection of these factors on representation and salary is unknown.

Background: Although the Impella device has an established role in high-risk percutaneous intervention and cardiogenic shock, its role in open cardiac surgery remains unclear. We undertook this study to better understand the role of Impella support in cardiac surgical intervention.

Methods: This is a retrospective cohort study of consecutive patients who underwent cardiac surgery with surgically placed Impella 5.

Article Synopsis
  • LVAD implantation significantly improves patient functional status, as shown by the New York Heart Association (NYHA) functional class, with most patients showing improvement at both 6-month and 12-month follow-ups.
  • A retrospective study of 151 patients found that 92.62% improved at 6 months, with many achieving class I or II symptoms, and this improvement remained stable over 2 years.
  • The study identified ischemic heart failure as a strong predictor of sustainable functional improvement following LVAD implantation, highlighting the potential benefits for high-risk patients.

Background: It has long been held that the safe duration of hypothermic circulatory arrest (HCA) is at least 25 to 30 minutes. However, this belief is based primarily on clinical outcomes research and has not been systematically investigated using more sensitive brain imaging and neurocognitive assessments.

Methods: This exploratory substudy of the randomized Cognitive Effects of Body Temperature During Hypothermic Circulatory Arrest (GOT ICE) trial, which compared outcomes for deep vs moderate hypothermia during aortic arch surgery, investigated the frequency of neurocognitive and structural and functional magnetic resonance imaging (MRI) deficits with HCA of short (<20 minutes) duration.

Objective: Long-term outcomes after multivalve cardiac surgery remain underevaluated.

Methods: Medicare administrative claims from 2008 to 2019 identified beneficiaries undergoing multivalve surgery. Operative characteristics were doubly adjudicated using International Classification of Diseases and Current Procedural Technology codes.

Data on the long-term outcomes of prosthesis patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI) remain controversial. This study aimed to investigate the incidence and clinical outcomes of measured PPM (PPM) and predicted PPM (PPM) in patients who underwent TAVI. This is a retrospective analysis of 3,016 patients who underwent TAVI at a large health care system between 2012 and 2021.

Importance: Physician burnout has reached crisis levels. Supportive leadership is one of the strongest drivers of physician well-being, and monitoring supervisor support is key to developing well-being focused leadership skills. Existing measures of leader support were designed within "direct report" supervision structures limiting their applicability to matrixed leadership reporting structures where direct reports are not the predominant norm.

Valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) has been associated with favorable outcomes in patients with degenerated stentless bioprosthesis. However, whether the outcomes after ViV TAVR for failed stentless bioprosthesis differ between balloon-expandable valves (BEVs) and self-expanding valves (SEVs) remains unknown. Therefore, we retrospectively analyzed 59 consecutive patients who underwent ViV TAVR for failed stentless bioprsothesis with BEVs (n = 42) versus SEVs (n = 17) in a single-health care system between 2013 and 2022.

Article Synopsis
  • Perioperative blood transfusions during coronary artery bypass graft (CABG) surgery can lead to negative outcomes and increased costs, prompting the development of risk assessments to better manage transfusion needs.
  • A study analyzed over 1.2 million CABG operations, finding that more than half required transfusions, and created predictive models using variables like age and preoperative hematocrit to help estimate transfusion likelihood and volume.
  • The resulting risk assessment tools showed strong accuracy in predicting transfusion needs, helping surgeons make informed decisions and optimize the use of blood products for better patient outcomes.

Background: Among patients with bicuspid aortic valves (BAV) who are potential candidates for valve-sparing root replacement (VSRR), the long-term durability of this technique is not well understood. This study aimed to compare the clinical and echocardiographic outcomes of VSRR in those with BAV and tricuspid aortic valve (TAV) morphology.

Methods: This was a retrospective analysis of patients who underwent VSRR between 2007 and 2021 at a single center.

Background: Diversity in the physician workforce improves patient care, physician well-being, and innovation. Workforce diversity is dependent on fair compensation that is unbiased by race or ethnicity. The purpose of this study was to determine whether a disparity of representation and salary on the basis of race or ethnicity exists in academic cardiothoracic surgery.

In acute coronary syndromes (ACS), revascularization is the standard of care. However, trials comparing contemporary coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are limited. Optimal revascularization in patients with multivessel coronary artery disease (MV-CAD) presenting with ACS is unclear.

Transcatheter tricuspid valve intervention (TTVI) has recently emerged as a promising alternative to surgery for tricuspid regurgitation (TR). However, a significant proportion of patients fail screening for TTVI, and little is known about their characteristics and natural history. This study sought to investigate causes of screen failure and outcomes of patients declined for TTVI.

Proximal radial artery (PRA) access for cardiac catheterization is safe but can jeopardize subsequent use of the artery because of occlusion. Distal radial artery (DRA) access in the anatomical snuffbox preserves the RA but safety and potential detrimental effects on hand function are unknown. We aimed to assess hand function and complications after DRA and PRA.

Article Synopsis
  • Doctors studied patients who had heart surgery to see how many got a blood clot in their leg (DVT) after the procedure.
  • They found that none of the 211 patients developed DVT, which is good news!
  • There were a few other health problems like bleeding and a stroke, but the overall risk of DVT was very low for those patients getting proper care.

Background: In March 2022, a COVID-19 outbreak disrupted the global supply of iodine contrast media (ICM). Healthcare systems implemented contrast-saving strategies to maintain their remaining ICM supplies. This study sought to determine the impact of contrast shortage on the incidence of contrast-associated acute kidney injury (CA-AKI).
