Background: Aortic regurgitation (AR) is a prevalent valve disease with a long latent period to symptoms. Recent data has suggested the role of novel markers of myocardial overload in assessing onset of decompensation.

Method: We sought to evaluate the role of unsupervised cluster analyses in identifying different clinical clusters, including clinical status, and a large number of echocardiographic variables including left ventricular (LV) volumes, and their association with mortality.

Background: The ideal timing for surgery in asymptomatic chronic aortic regurgitation (AR) remains unclear. New thresholds for left ventricular ejection fraction (LVEF), left ventricular (LV) indexed end-systolic volume (iESV), and global longitudinal strain (GLS) have been associated with mortality in these patients. These represent markers of early LV dysfunction.

Article Synopsis
  • The study investigates how the timing of coronary artery bypass grafting (CABG) after an acute heart attack affects patient outcomes, focusing on both early and long-term mortality rates.
  • Researchers analyzed data from 1,631 patients who had CABG, categorizing them based on whether surgery was performed within 24 hours, between 1 to 7 days, or more than 7 days post-heart attack.
  • Results showed that while early mortality rates were similar across timing groups, those who had CABG more than 7 days after an attack faced significantly higher risks of late mortality, particularly in patients with non-ST-segment elevation myocardial infarction.

Article Synopsis
  • The study analyzed over 148,000 coronary artery bypass grafting (CABG) cases to assess risks associated with clopidogrel (a blood thinner) taken within 5 days prior to surgery.
  • It found that patients who had used clopidogrel had slightly higher operative mortality and significantly higher rates of mediastinal reexploration for bleeding and blood product use compared to those who hadn't taken the drug.
  • The risks decreased the longer the wait after stopping clopidogrel, reaching similar outcomes for surgeries performed 3 days after the last dose compared to 5 days, suggesting 3 days may be a sufficient waiting period before CABG.

  • - The study aimed to explore the occurrence of restricted cusp motion (RCM) during bioprosthetic tricuspid valve replacement (TVR) and its risk factors and effects on patient outcomes.
  • - Out of 476 patients analyzed from 2012 to 2022, 31.5% exhibited RCM, with 13.2% having complete immobility and 18.3% showing limited movement of the valve cusp.
  • - The research found that certain factors, like the type of valve used and patient-specific measurements, significantly influenced the likelihood of RCM, which was linked to a higher mortality risk, highlighting the importance of careful prosthesis selection.

Article Synopsis
  • - This study reviews patients who had tricuspid valve (TV) repair during surgery for degenerative mitral valve (MV) disease, focusing on the need for permanent pacemaker (PPM) implantation after the procedure across 404 cases from 2001 to 2022.
  • - The findings revealed that 8.7% of patients required PPM implantation post-surgery, primarily due to high-degree AV block, with older age identified as a significant risk factor for this complication.
  • - The conclusions suggest that while PPM needs are relatively common after TV repair during MV surgery, careful patient selection and surgical techniques might help to lower the associated risks and improve patient outcomes.

  • Limited data on the outcomes of delayed sternal closure (DSC) in adults with congenital heart disease have been gathered from a review of 159 patients over 30 years.
  • Among the 112 patients undergoing DSC, those closed within 4 days had lower early mortality (6.8%) compared to those closed after 4 days (32%), and higher ages and specific medical conditions were linked to worse outcomes.
  • Despite the risks, hospital survivors showed no significant difference in late survival between those with brief DSC (≤4 days) and prolonged DSC (>4 days), indicating that a shorter DSC duration may lead to better initial outcomes.

Background: Transthoracic aortic cross-clamp and endoaortic balloon occlusion have both been shown to have comparable safety profiles for aortic occlusion. Because most surgeons use only one technique, we sought to compare the outcomes when a homogeneous group of surgeons changed their occlusion technique from aortic cross-clamp to balloon occlusion.

Methods: We changed our technique from aortic cross-clamp to balloon occlusion in November 2022.
