PERCUTANEOUS SNARE-RETRIEVAL OF INTRACARDIAC THROMBUS UNDER FLUOROSCOPIC AND TRANSESOPHAGEAL ECHOCARDIOGRAPHY GUIDANCE: CASE REPORT AND SYSTEMATIC REVIEW

Intracardiac foreign bodies (IFB) are rare clinical conditions.There are now several reports on the percutaneous retrieval of IFB under fluoroscopy.However, some IFB are not radiopaque, and retrieval requires combined fluoroscopic and ultrasound guidance.We report the case of a bedridden 23-year-old male patient with T-lymphoblastic lymphoma treate

It is important to study the effects of pyrolysis and ablation of heat protection material in AC Adaptor integrated design of hypersonic vehicles.In order to predict and assess the material pyrolysis and ablation effects on target signatures and microwave communication, based on chemical nonequilibrium gas dynamic equations and solid heat transfer

Short-wave perturbations in a relaxing medium, governed by a special reduction of the Ostrovsky evolution equation, and later derived by Whitham, are studied using the gradient-holonomic Masturbators integrability algorithm.The bi-Hamiltonicity and complete integrability of the corresponding dynamical system is stated and an infinite hierarchy of c

The detection and tracking of small and weak maneuvering radar targets in complex electromagnetic environments is still a difficult problem to effectively solve.To address this problem, this paper proposes a dynamic programming tracking-before-detection method based on long short-term memory (LSTM) network value function(VL-DP-TBD).With the help of
