Article Abstract
Objective: The aim was to evaluate the predictive value of thromboelastometry for postoperative blood loss in adult cardiac surgery with cardiopulmonary bypass.
Design: Retrospective cohort study and systematic review of the literature.
Setting: A tertiary university hospital.
Participants: 202 patients undergoing elective cardiac surgery.
Interventions: Thromboelastometry was performed before cardiopulmonary bypass and 3 minutes after protamine administration.
Measurements And Main Results: The cohort study showed that the preoperative and postoperative thromboelastometric positive predicting value was poor (0%-22%); however, the negative predicting value was high (89%-94%). The systematic review of the literature to evaluate the predictive value of thromboelastometry for major postoperative bleeding in cardiac surgery resulted in 1,311 articles, 11 of which were eligible (n = 1,765; PubMed and Embase, until June 2016). Two studies found a good predictive value, whereas the other 9 studies showed a poor predictability for major postoperative bleeding after cardiac surgery. The overall negative predicting value was high.
Conclusions: Thromboelastometry does not predict which patients are at risk for major postoperative bleeding.

To analyze in-hospital mortality in children undergoing congenital heart interventions in the only public referral center in Amazonas, North Brazil, between 2014 and 2022. This retrospective cohort study included 1041 patients undergoing cardiac interventions for congenital heart disease, of whom 135 died during hospitalization. Records were reviewed to obtain demographic, clinical, and surgical data.

The purpose of this study is to identify 35-year trends in adult congenital heart disease (ACHD) heart transplant volume, transplant centers, patient characteristics, and longitudinal survival up to ten years. We performed a retrospective review of ACHD patients (≥18 years) who underwent heart transplantation (N = 2,297 transplants) between January 1, 1988, and December 31, 2022, using the United Network for Organ Sharing Database. Trends in transplant volume, transplant centers, patient characteristics, and longitudinal survival were analyzed.

Importance: Right anomalous aortic origin of a coronary artery (R-AAOCA) is a rare congenital condition increasingly diagnosed with the growing use of cardiac imaging. Due to dynamic compression of the anomalous vessel, invasive fractional flow reserve (FFR) during a dobutamine-atropine volume challenge (FFR-dobutamine) is considered the reference standard. A reliable alternative method is needed to reduce extensive invasive testing, but it remains uncertain whether noninvasive imaging can accurately assess the hemodynamic relevance of R-AAOCA.

Limited vascularization and ischemia are major contributors to the chronicity of wounds, such as ulcers and traumatic injuries, which impose significant medical, social, and economic burdens. These challenges are particularly pronounced in patients with spinal cord injury (SCI), a disabling condition associated with vascular dysfunction, infections, and impaired peripheral circulation, complicating the treatment of pressure injuries (PIs) and the success of reconstructive procedures like grafts and flaps. Regenerative medicine aims to address these issues by identifying effective cellular therapies to restore vascular beds.
