Objectives: This study was performed to evaluate an additional echocardiographic spectral Doppler marker, which would identify severe aortic stenosis (AS).
Background: Echocardiography is most commonly utilized to assess AS and has been validated against invasive measurements. However, the data obtained are not always in agreement, leaving a conundrum regarding the true severity of AS and can lead to other diagnostic procedures. This highlights the importance of improved noninvasive diagnostic techniques.
Methods: Forty-eight indeterminate cases of calcific AS that had been previously evaluated by both echocardiography and cardiac catheterization were included in the study, using cardiac catheterization as the gold standard for calculation of aortic valve area (AVA). The intensity of opening and closing of the aortic valve, represented by bright vertical deflections on the CW spectral waveform, was quantified using ImageJ software to generate pixel intensity histograms to create opening and closing click (OC and CC) ratios. These ratios were compared with echocardiographic variables and catheterization AVA.
Results: Thirty-five patients were found to have severe AS and 13 patients were found to have nonsevere AS, as assessed by cardiac catheterization. CC ratio was found to be a significant predictor of severe AS with an OR 0.024 (95% CI: 0.002-0.378, P = .0079). Adding CC to a model using standard echocardiographic parameters resulted in significant improvement in the C-statistic (0.693 to 0.835, P = .0134).
Conclusions: An additional Doppler marker measuring the aortic valve CC ratio has been found to improve detection of severe AS.

Three-Dimensional Rotational Angiography to Guide Cardiac Catheterization in Critical Infants Below 5kg of Body Weight.

Department of Pediatric Cardiology, Wilhelmina Children's Hospital, University Medical Center of Utrecht, Utrecht, the Netherlands.
Background: Three-dimensional rotational angiography (3DRA) is a promising advancement to guide cardiac catheterizations. It is used with restraint in critically ill infants with congenital heart disease (CHD) due to the lack of research conducted within this patient group.
Methods: Data of all infants with CHD and a body weight <5 kg who underwent cardiac catheterization with the use of 3DRA between November 2011 and April 2021 were retrospectively analyzed.

Transcatheter aortic valve repair (TAVR) presents a minimally invasive alternative to traditional surgical valve replacement, albeit not without its own set of complications. A rare complication is the infolding of the self-expanding valve, which can precipitate cardiac arrest. The estimated incidence rate of this complication stands at 1.

Background: Routine preprocedural fasting before cardiac catheterization remains common practice, despite a lack of robust evidence to support this practice. We investigated the impact of a liberal nonfasting strategy vs a standardized nil per os (NPO) regimen prior to cardiac catheterization.
Methods: Adult inpatients undergoing elective or urgent cardiac catheterization were randomized (1:1 ratio) to either NPO past midnight or ad libitum intake of liquids and solids (without dietary constraints) until immediately prior to the procedure.
Implementing Patient Protection Radiation Dose Alerts for Pediatric Cardiac Catheterization Examinations.

Background: Advancements in cardiac catheterization have improved survival for pediatric congenital heart disease patients, but the associated ionizing radiation risks necessitate ethical consideration.
Methods: This study presents an empirical model, developed from 3131 unique pediatric procedures, to establish alert levels based on a patient's lateral thickness of the thorax for various procedural categories during diagnostic or interventional cardiac catheterization. The model uses linear regression of logarithmic reference air kinetic energy released per unit mass (KERMA) and air KERMA area product, also referred to as dose area product, to set alert levels at the top 95% and 99% of patient data.

The clinical presentation and epidemiology of infective endocarditis (IE) have evolved over time. While the cornerstones of IE treatment remain antimicrobial therapy and surgery, percutaneous mechanical aspiration (PMA) has emerged as an option for carefully selected patients as a complementary modality, based on retrospective data, case series, and expert experience. In this comprehensive review, we summarize the proceedings from an inaugural summit dedicated to the discussion of PMA in the global management of IE, consisting of experts across multiple disciplines from diverse geographic regions and care environments.
