“…The ICE catheter is positioned in the descending aorta and the probe aimed at the infundibulum of the PDA, depicting continuous shunt flow and monitoring all procedural steps 28 ( Figure 8 ). The advantages of ICE demonstrated for device closure of IAC, including lower radiation exposure and shorter fluoroscopy times, can be potentially transferred to device closure of peri-membranous VSDs and PDAs.…”

Current interventional procedures in structural heart disease and cardiac arrhythmias require peri-interventional echocardiographic monitoring and guidance to become as safe, expedient, and well-tolerated for patients as possible. Intracardiac echocardiography (ICE) complements and has in part replaced transoesophageal echocardiography (TEE), including real-time three-dimensional (RT-3D) imaging. The latter is still widely accepted as a method to prepare for and to guide interventional treatments. In contrast to TEE, ICE represents a purely intraprocedural guiding and imaging tool unsuitable for diagnostic purposes. Patients tolerate ICE much better, and the method does not require general anaesthesia. Accurate imaging of the particular pathology, its anatomic features, and spatial relation to the surrounding structures is critical for catheter and wire positioning, device deployment, evaluation of the result, and for ruling out complications. This review describes the peri-interventional role of ICE, outlines current limitations, and points out future implications. Two-dimensional ICE has become a suitable guiding tool for a variety of percutaneous treatments in patients who are conscious or under monitored anaesthesia care, whereas RT-3DICE is still undergoing clinical testing. Continuous TEE monitoring under general anaesthesia remains a widely accepted alternative.

“…Though trans‐aortic echocardiography was reported to guide DC‐PDA , TPE has several advantages. Trans‐aortic echocardiography needs to place an 8 French sheath into the femoral artery, and that is undesirable in patients on anti‐coagulation therapy.…”

“…Overcoming this disadvantage of TEE, intra‐cardiac echocardiography (ICE), especially using AcuNav™ (Biosense Webster Inc, Diamond Bar, CA, USA), has been developed and widely used in catheter intervention for inter‐atrial septum, closure of atrial septal defect or perforation of inter‐atrial septum, with local anesthesia . Recently ICE catheter has expanded its application and was used in the other types of catheter interventions including percutaneous pulmonary or aortic valve replacement and balloon valvuloplasty . However, there is no report of the ICE catheter used in the pulmonary artery to guide DC‐PDA.…”

This paper presents a mass flow rate control method for solenoid-based injectors in open-loop, that is, without physical sensor feedback. Measuring the mass flow rate in injectors is important because the performance of the injector determines fuel consumption and emissions. While it is possible to perform this control using different types of sensors, this would increase the cost and reduce the reliability. With this study, it was aimed to control the mass flow rate of solenoid-based injectors using continuous switching control to regulate the injector’s needle displacement without using sensors. For this purpose, a solenoid-actuated injector prototype was created. Model-based estimators were used to determine the states of the injector, while a super-twisting sliding mode controller was used to track the desired mass flow rate references. The results of the experiments showed that tracking for sinusoidal, triangular, and square trajectories yielded a mass flow rate percent error of less than 1.06. The proposed open-loop control algorithm can be used to track different mass flow rate references in internal combustion engines.
