It is often said that those entering the medical field must begin by learning a new language: the language of biology and clinical medicine. Early in training, students find themselves barraged by a myriad of new terms, some of them replacing the old monikers they had known since childhood.
Now commercially available in Europe, CAT RX is designed to navigate tortuous coronary anatomy while maintaining sustained mechanical aspiration with the Penumbra ENGINE. Traditional modalities utilizing syringe aspiration suffer from diminished vacuum once fluid enters the system.
With unmatched accuracy, we can tailor treatments to each patient's unique anatomy, enhancing safety and efficacy.” “We Our team has leveraged the precision and safety of robotics to treat patients that often have few other options for care.
Hemothorax caused by a right intercostal artery (ICA) injury behind the left atrium (LA) is a potentially fatal complication during pulmonary vein isolation. However, their anatomical relationship has not been fully elucidated.
Persistent left superior vena cava (PLSVC) is a common anomaly in the thoracic venous system, accounting for 0.2-4.3% of all congenital cardiac anomalies However, isolated PLSVC may occur in 10-20% of PLSVC cases.
The comprehensive curriculum, meticulously crafted by industry experts, featured enlightening lectures, hands-on sessions with cutting-edge device, and an anatomy workshop that provided doctors with bull hearts and specialized tools.
Increased mass personalization, enabled by 3D technologies, is enhancing healthcare by enabling tailored treatment plans and interventions that cater to the unique anatomy of individual patients, resulting in improved outcomes and patient satisfaction.
With advances in multimodality imaging, 3D echocardiography, improved understanding of TV anatomy, and pathophysiological mechanisms of primary and secondary regurgitation, as well as favorable data with transcatheter therapies, the field of TV management is rapidly evolving.
The FARAWAVE catheter is used to treat a range of pulmonary vein anatomies using an over-the-wire catheter with variable basket and flower shapes, allowing the device to adapt to individual patient anatomies. These configurations reinforce ease-of-use for physicians and promote reproducible procedures between operators.
ObjectiveSpinal cord ischemia due to damage or occlusion of the orifices of aortic segmental arteries (ASA) is a serious complication of open and endovascular aortic repair.
Focal AT at the aorta-mitral annulus conjunction (AMC) is uncommon. Hence, the electrophysiological and ablation target characteristics are poorly described.
