Endoscopic Mitral Surgery in Noonan Syndrome-Case Report and Considerations.
J Clin Med
January 2025
Department of Surgery IV, George Emil Palade University of Medicine, Pharmacy, Science and Technology of Targu Mures, 38 Gheorghe Marinescu Street, 540139 Targu Mures, Romania.
: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy.

Objective: This study sought to present the endovascular approach of transcatheter aspiration using the FlowTriever (Inari Medical) aspiration system for high surgical risk patients with right-sided infective endocarditis.
Key Steps: General anesthesia and transesophageal echocardiogram guidance; ultrasonography-guided femoral vein access, preclosure sutures, and insertion of a 24-F sheath; insertion of straight 24-F aspiration cannula over a stiff wire, parked in the superior vena cava; introduction of a 20-F curved cannula inside the 24-F cannula to create a telescopic assembly; accurate positioning using the right ventricle inflow/outflow projection in biplane mode; adjustment of the curved cannula radius by sliding the inner cannula in and out inside the mother cannula; manual aspiration of the vegetation; Postaspiration transesophageal echocardiogram assessment.
Potential Pitfalls: Avoid leaflet and annular injury and account for potential embolization.
Effect of the prolene ripcord suture on the baerveldt tube position: A case study.
Eur J Ophthalmol

Department of Ophthalmology, King's College Hospital, London, UK.
A 42 year old Afro-Caribbean man underwent Baerveldt Glaucoma Implant (BGI) surgery for silicone oil induced glaucoma. Three months following initial surgery, the 3-0 prolene ripcord suture was removed. Anterior segment OCT demonstrates the position of the intracameral portion of the tube before and after the 3/0 prolene stent suture (PSS) removal.

1st Department of Arrhythmia, National Institute of Cardiology, 42 Alpejska Street, 04-628 Warsaw, Poland.
Background: Transvenous lead extraction (TLE) has become an essential component of lead management strategies, but it carries the risk of severe complications, including damage to the tricuspid valve. Currently, there are no established predictors that can help prevent these complications.
Case Summary: An 84-year-old male with a dual-chamber pacemaker was admitted to the hospital due to a pocket fistula resulting from a local infection.
Smooth braking control of excavator hydraulic load based on command reshaping.

Excavators, a type of human-operated construction machinery, suffer from poor hydraulic load braking stability, which seriously affects operator comfort. To address this challenge, this study investigates load braking laws through model analysis and designs an open-loop control algorithm called command reshaping, which can prolong the small-opening time of the main valve by segmentally adjusting the joystick command during load braking and then actively adjusting the key parameters reflecting the system's kinetic-potential energy state, thereby suppressing braking oscillations. The experimental results based on a 1.
