Evaluation of the pulmonary vein ostia during the cardiac cycle using electrocardiography-gated cardiac computed tomography in cats

Frontiers in Veterinary Science, 2022
Several studies in humans have provided detailed descriptions of the anatomy of the pulmonary veins (PVs) and their ostia for the implementation of thoracic interventions, such as radiofrequency ablation, for patients with atrial fibrillation.

A Randomized Controlled Trial Comparing the TruSteer and FXD Double Curve Delivery Systems for Left Atrial Appendage Occlusion With the Watchman FLX Pro Device—The GUIDE‐LAAO Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Deflectable delivery systems have been introduced to enhance coaxial alignment and procedural efficacy during left atrial appendage occlusion (LAAO), yet randomized comparisons with conventional fixed‐curve systems are lacking. Aims The GUIDE‐LAAO trial evaluated whether the TruSteer deflectable delivery system is non‐inferior to ...

A Detailed Structural Classification of Cross Vault in Ostia [PDF]

Athens Journal of Architecture
In ancient Rome, the use of vaulted structures built by using Roman concrete allowed for the construction of high-rise buildings. This architectural influence can be evident in Ostia, the Roman port city.

Percutaneous Transaxillary Access for Large‐Bore Cardiovascular Interventions: Evidence, Technique, and Complication Management

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Percutaneous transaxillary access is an established alternative to transfemoral large‐bore arterial access for transcatheter structural heart interventions and mechanical circulatory support (MCS). Although useful for overcoming hostile iliofemoral anatomy and providing prolonged support and patient mobilization in case of MCS, the axillary ...

A CASE OF THE LEFT ATRIUM APPENDAGE OCCLUSION, SUGGESTIONS ON THE CLINICAL FIELD DEVELOPMENT

Российский кардиологический журнал, 2017
Aim. To evaluate the possibility of hybrid procedure that includes single-moment cryoballoon isolation of pulmonary veins (PV) ostia and implantation of occluder into the left atrium appendage (LAA) in patients of high thromboembolic and hemorrhagic risk

Validation of an Automated Artificial Intelligence‐Driven Planner for Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.

Radiographic identification and description of the equine middle conchal sinus (ethmoidal sinus): Implications for diagnosing middle conchal sinusitis

Equine Veterinary Journal, EarlyView.
Abstract Background The middle conchal sinus (MCS) (ethmoidal sinus) remains one of the least understood equine paranasal compartments. Despite recognition of its involvement in sinonasal disease, disorders of the MCS often remain underdiagnosed in the absence of computed tomographic (CT) imaging due to limited anatomical understanding and challenges ...

Laser neoureterocystostomy to treat ectopic ureters

Equine Veterinary Journal, EarlyView.
Abstract Background Ureteral ectopia is an uncommon but clinically important congenital abnormality in horses. If left untreated, it can lead to persistent dermatitis, urinary tract infections, and failure to thrive. Surgical correction is necessary, but traditional approaches have produced mixed results with high morbidity.
