Risk Estimation of Severe Primary Graft Dysfunction in Heart Transplant Recipients Using a Smartphone.

Background: Currently, there are no standardized guidelines for graft allocation in heart transplants (HTxs), particularly when considering organs from marginal donors and donors after cardiocirculatory arrest. This complexity highlights the need for an effective risk analysis tool for primary graft dysfunction (PGD), a severe complication in HTx. Existing score systems for predicting PGD lack superior predictive capability and are often too complex for routine clinical use.

Perioperative infarction during coronary bypass surgery: an attempt to refine the diagnostic criteria using data from a retrospective case-control study.

Objective: The definition of coronary artery bypass graft (CABG)-associated myocardial infarction (MI) is controversial because the postoperative increases in cardiac enzyme activities are multifactorial in origin.

Methods: We performed a retrospective case-control study of patients who experienced perioperative MI (cardiac enzyme release, electrocardiographic changes, dysfunction on echocardiography) and those without ischemia to identify risk factors and enzyme activity thresholds.

Results: The estimated incidence of CABG-associated MI was 2.

Comparative analysis of intraoperative thermal and optical imaging for identification of the human primary sensory cortex.

Significance: The precise identification and preservation of functional brain areas during neurosurgery are crucial for optimizing surgical outcomes and minimizing postoperative deficits. Intraoperative imaging plays a vital role in this context, offering insights that guide surgeons in protecting critical cortical regions.

Aim: We aim to evaluate and compare the efficacy of intraoperative thermal imaging (ITI) and intraoperative optical imaging (IOI) in detecting the primary somatosensory cortex, providing a detailed assessment of their potential integration into surgical practice.

Role of the New Physical Examination Minor Criterion (New Heart Murmur) for the Diagnosis of Infective Endocarditis.

Among 3127 episodes of suspected infective endocarditis, the 2023 Duke-International Society for Cardiovascular Infectious Diseases clinical criteria showed an accuracy of 90% for infective endocarditis diagnosis. A new heart murmur was present in 690 (22%) episodes. Excluding imaging and surgical findings decreased the accuracy to 73%, while using the physical examination criterion slightly improved the accuracy to 78%.
