Observational StudyBedside Chest Ultrasound in Postoperative Pediatric Cardiac Surgery Patients: Comparison With Bedside Chest Radiography.
The primary objective was to study the degree of agreement between the chest ultrasound (CUS) studies and chest x-ray (CXR) studies in postoperative pediatric cardiac surgical patients regarding the diagnosis of thoracic abnormalities, and also to compare the diagnostic performance of CUS in reference to CXR for the detection of thoracic abnormalities. The secondary objective was to compare the necessity for interventions done on the basis of CUS and CXR findings in the postoperative setting. ⋯ The degree of agreement between CUS and CXR studies was substantial for atelectasis, interstitial edema, and diaphragmatic weakness. The degree of agreement between CUS and CXR studies was almost perfect for pneumothorax and fair for pleural effusion. More CUS studies detected intrathoracic pathologies than CXR studies. The CUS also detected abnormalities earlier than CXR and was found to be useful for the early institution of intervention therapy in patients with interstitial edema and atelectasis. It would be reasonable to conclude that CUS may be considered in some instances as an alternative to CXR.

Review Meta AnalysisCardiovascular and Respiratory Safety of Sedation Strategies Used in Transesophageal Echocardiography: A Systematic Review Incorporating Network Meta-Analysis.
TRANSESOPHAGEAL ECHOCARDIOGRAPHY (TEE) is carried out in various clinical settings, with an increasing importance, and sedation usually is required to perform it. Several sedative agents are available, and the authors aimed to compare the cardiovascular and respiratory safety of the strategies used for sedation in TEE through a systematic review with network meta-analysis (NMA). The MEDLINE, CENTRAL, EMBASE, and PsycInfo databases were searched in December 2020 for randomized clinical trials (RCTs) comparing sedation strategies for patients undergoing TEE. ⋯ Based on the NMA, the drugs with a higher likelihood of decreasing both SBP and HR were dexmedetomidine and midazolam. All of the drugs led to a small decrease (only statistically significant for midazolam) in SpO2, with the systematic use of supplemental O2 in some trials. The risks of hypotension, bradycardia, or desaturation were not significantly different among the evaluated drugs.

ReviewAortic Valve Repair Using HAART 300 Geometric Annuloplasty Ring: A Review and Echocardiographic Case Series.
Aortic valve repair (AVr) aims to preserve the native aortic leaflets and restore normal valve function. In doing so, AVr is a more technically challenging approach than traditional aortic valve replacement. Some of the complexity of repair techniques can be attributed to the unique structure of the functional aortic annulus (FAA), which, unlike the well-defined mitral annulus, is comprised of virtual and functional components. ⋯ As with other AVr subtypes, this procedure has a learning curve. There are unique surgical and echocardiographic aspects of AVr with GAR, including the appearance of the LVOT, the aortic valve leaflets, and their motion which cardiac anesthesiologists and echocardiographers must be familiar with. In this work, using an eight-patient echocardiographic case series, we provide an overview of this novel AVr technique, including some unique aspects of device sizing, patient selection, expected post-repair echocardiographic features, and a review of outcomes data.
