The gold-standard treatment for prosthetic-valve paravalvular leakage is surgery to repair or replace the valve; however, the morbidity and mortality rates cannot be ignored, and some patients are poor surgical candidates. The percutaneous closure of such defects is possible, and different devices are being used for this purpose. In almost all instances, a femorofemoral or femorojugular wire loop is constructed to deliver the closure device. Herein, we present the case of a 61-year-old man in whom a mitral paravalvular leak was successfully closed with use of the Amplatzer Duct Occluder II, via retrograde approach under 3-dimensional transesophageal echocardiographic guidance, without the use of a wire loop. To the best of our knowledge, this is the 1st report of retrograde device deployment without the construction of an arteriovenous wire loop, and the 1st case in which the Amplatzer Duct Occluder II was used for the percutaneous closure of a mitral paravalvular leak.

Iatrogenic type A aortic dissection (IAAD) is a rare but life-threatening complication of percutaneous coronary intervention (PCI), often presenting significant therapeutic challenges. A looped guidewire between the right subclavian artery and brachiocephalic artery during coronary angiography (CAG) via right radial artery access can complicate catheter manipulation. This report discusses the case of a 58-year-old hypertensive female patient who developed aortic dissection during PCI, specifically due to wire manipulation at the brachiocephalic loop.

Considering the fault tolerance of EMB (Electro-Mechanical-Brake) braking failure and anti-rollover control at the same time is one of the urgent problems to be solved in the driving safety of X-by-wire vehicles. Accurate rollover index is a key part of anti-rollover control. Aiming at the problem that the traditional rollover index reflects that the unsprung mass of the vehicle is insufficiently affected by road excitation, a tripped vehicle rollover dynamic model is established based on single-wheel braking failure, and a rollover evaluation index NLTR (New Load-Transfer-Rate) suitable for braking failure is proposed.

Purpose: To demonstrate the Modified Balloon Nose Cone Technique to avoid passage of the aortic valve in endovascular branched arch repair.

Technique: The technique is demonstrated in a 54-year-old patient after previous open repair of the ascending aorta and mechanical aortic valve replacement due to type A aortic dissection. The delivery system of a custom-made stent-graft with 3 inner branches was modified by subtotally sawing off its nose cone.

Background: Chronic total occlusions with ambiguous proximal caps present a significant challenge in endovascular interventions of patients with Buerger's disease.

Objective: We aimed to evaluate the effectiveness of transpedal retrograde wire just marker technique in patients with Buerger's disease presenting proximal cap ambiguity and flush occlusions.

Methods: Seventeen patients with the diagnosis of Buerger's disease who had below the knee artery chronic total occlusions with ambiguous proximal caps were enrolled.

This paper proposes a control strategy for the variable boost characteristics of electronic hydraulic brake (EHB) systems based on the driving style in response to the nonlinear challenges faced by the EHB systems in intelligent driving under complex personalized requirements. Initially, the working principle of the active braking of the EHB-booster was analyzed, and equivalent dynamic models and Karnopp friction models were established. Subsequently, by identifying the displacement and velocity parameters of the brake pedal, three types of variable boost characteristics-sporty, comfortable, and standard-were designed to satisfy the requirements of different driving styles.
