The intra-aortic balloon pump (IABP) is a mechanical device that increases myocardial oxygen perfusion and indirectly increases cardiac output through afterload reduction. Since its inception, the IABP has been a mainstay of cardiac support devices, utilized as a temporizing measure in patients with or prone to developing cardiogenic shock that are awaiting definitive treatment. Systolic anterior motion (SAM) of the mitral valve is a well-described phenomenon that can precipitate hemodynamic collapse by obstructing the left ventricular outflow tract in a subset of patients with cardiac pathology, most notably hypertrophic obstructive cardiomyopathy (HOCM)...

BACKGROUND: Ventricular septal defect (VSD) is the most common type of congenital heart abnormality with perimembranous VSD (pmVSD) accounting for ∼70% of all VSD. Nowadays, transcatheter closure is the first choice for suitable pmVSD. However, there was no report about closing the large oval-shaped VSD percutaneously. CASE SUMMARY: A 34-year-old male with known VSD was referred for transcatheter closure after failed attempts in other hospital. Patient had been diagnosed with VSD at a young age, but he was lost to follow-up...

The cyclical changes in sex hormones across the menstrual cycle (MC) are associated with various biological changes that may alter resting metabolic rate (RMR) and body composition estimates. Hormonal contraceptive (HC) use must also be considered given their impact on endogenous sex hormone concentrations and synchronous exogenous profiles. The purpose of this study was to determine if RMR and dual-energy X-ray absorptiometry body composition estimates change across the MC and differ compared with HC users...

Treatment effect estimation (TEE) is the task of determining the impact of various treatments on patient outcomes. Current TEE methods fall short due to reliance on limited labeled data and challenges posed by sparse and high-dimensional observational patient data. To address the challenges, we introduce a novel pre-training and fine-tuning framework, KG-TREAT, which synergizes large-scale observational patient data with biomedical knowledge graphs (KGs) to enhance TEE. Unlike previous approaches, KG-TREAT constructs dual-focus KGs and integrates a deep bi-level attention synergy method for in-depth information fusion, enabling distinct encoding of treatment-covariate and outcome-covariate relationships...

Climate change is an existential threat to humanity. While the healthcare sector must manage the health-related consequences of climate change, it is a significant contributor to greenhouse gas emissions, responsible for up to 4.6% of global emission, aggravating global warming. Within the hospital environment, the three largest contributors to greenhouse gas emissions are the operating theatre, intensive care unit and gastrointestinal endoscopy. Knowledge of the health-related burden of climate change and the potential transformative health benefits of climate action is important to all health professionals, as they play crucial roles in effecting change...

BACKGROUND: Water is one of the most essential nutrients for life. The water turnover (WT), total body water (TBW), and total energy expenditure (TEE) can be measured using the doubly labeled water (DLW) method. WT and TBW are lower in older adults than in young adults, and the former are susceptible to dehydration, necessitating to identify predictors of the WT in older adults. OBJECTIVE: The current study aimed to examine the association between WT and physical activity, physical function, and body composition in Japanese adults aged 65 years and above and identify predictors for WT in this population...

The Angiovac aspiration system has been used successfully for the removal of intravascular material or thrombus in the right-sided heart structures, vena cava, implantable cardiac defibrillator, or other devices. For infective endocarditis, it is reserved for the patients who warrant but are not good candidates for the surgery. The evidence regarding Angiovac aspiration of the infective endocarditis of the left-sided heart valves is scarce. The risk of complications, including thrombi fragmentation leading to systemic embolization, damage to the cardiac structures and tissue, and hemodynamic instability, precludes the widespread use of this procedure, especially for the left-sided lesions...

Stent migration is a rare but significant complication following endovascular procedures. Techniques for managing dislodged stents have included surgical, endovascular, and conservative approaches. This case details a patient who had a covered stent placed within the left renal vein which later migrated to the pulmonary artery causing damage to the tricuspid valve. The migrated stent was successfully removed using a percutaneous endovascular approach utilizing fluoroscopy and transesophageal echocardiogram guidance...

Intracardiac echocardiography (ICE) has emerged as an alternative to transesophageal echo (TEE) to guide left atrial appendage occlusion (LAAO). We established a protocol to select patients appropriate for ICE guidance. Patients undergoing LAAO with the Watchman or Watchman FLX device (Boston Scientific, Marlborough, MA) from January 2018-March 2022 at a large United States center were included. The novel protocol prospectively selected TEE or ICE guidance beginning in January 2020; previous LAAO procedures were retrospectively included...

BACKGROUND: Non-bacterial thrombotic endocarditis (NBTE) is a rare condition marked by sterile vegetations on cardiac valves, often linked to rheumatologic diseases, autoimmune disorders, and advanced solid malignancies. An early diagnosis and treatment of the associated clinical condition are mandatory, although they do not usually eliminate valvular vegetations, making anticoagulation essential to prevent embolic events. Despite variability, the prognosis of NBTE is usually unfavorable due to recurrent embolic events and the severity of the primary condition, typically advanced cancer...

BACKGROUND A paradoxical air embolism (PAE) occurs when air entering the central venous circulation reaches the systemic circulation, occurring through an intracardiac shunt or intrapulmonary shunting. Patients presenting for liver transplantation often have intrapulmonary shunting due to pulmonary arterial vasodilation, even in the absence of hepatopulmonary syndrome. Here, we present a case of hemodynamic collapse believed to be caused by a PAE, which was diagnosed intraoperatively with transesophageal echocardiography (TEE)...

We repaired a left anomalous aortic origin of coronary artery (AAOCA) using coronary ostium translocation/re-implantation. Re-repair was required due to suboptimal flow pattern in postoperative transesophageal echocardiography (TEE), confirmed with coronary angiography. We emphasize the importance of early recognition, diagnosis and intervention to deal with a problem with the coronary repair.
