Treatment of coronary artery disease has made strides over the last decades. Development of drug eluting stents (DES), coated with a polymer layer and an anti-proliferative drug to reduce neointimal hyperplasia, has reduced the incidence of in-stent-restenosis relative to treatment with bare metal stents. Patients treated with first generation DES more likely suffer from (very) late events which can be cause by the permanent presence of a polymer. Therefore second generation DES with more biocompatible coatings, and third generation DES, with very thin struts coated with biodegradable polymers, were developed...

A modern ventricular assist device (VAD) system comprises an implantable rotary blood pump and external components located outside the patient's body: a wearable controller connected to the pump via a percutaneous cable, wearable rechargeable batteries, battery charger, alternating- and direct-current power supplies, and a hospital device to control and monitor the system. If the blood pump is the "heart" of a VAD system, the controller is its "brain." The controller drives the pump's electrical motor; varies the pump speed or flow based on user commands or feedback signals; collects, processes, and stores data; performs self-diagnostics; transmits to and receives data from other system components, i...

BACKGROUND: Mask ventilation is routinely performed during anesthesia. Under some circumstances, it might be difficult to perform, such as in edentulous patients, due to inadequate mask seal. We developed a new device called NIPARA and studied its use For ventilation optimization in edentulous patients. METHODS: This randomized controlled trial included edentulous adults who had no other predictors of difficult airway, scheduled to undergo general anesthesia. Patients were assigned either to the NIPARA device group or to the control group (oral airway only)...

The increasing pandemic of heart failure is becoming a serious challenge for the health care system. The medical world is searching for solutions which could decrease its scale and improve patients' quality of life and prognosis. Telemanagement of heart failure patients is a new promising option. Technical and technological platforms to perform e-Health management in heart failure patients' homes have become available. This paper's aims are to present different forms of e-Health including telecare, home monitoring of cardiovascular implantable electronic devices, remote monitoring of hemodynamic implantable devices and telerehabilitation in providing optimal long term management for heart failure patients...

Atrial fibrillation has a significant impact on patient mortality and morbidity. In particular, stroke is a frequent complication associated with atrial fibrillation. In recent years, various treatment options have been developed that are based on the elimination of atypical electrically active atrial areas. Areas covered: This manuscript presents a new cryoablation probe from AtriCure Inc. In addition to describing the characteristics of the probe, we also discuss atrial fibrillation and its surgical therapy options as well as the basics of cryosurgery...

Atrial fibrillation is the most common cardiac arrhythmia. The development of electroanatomical mapping is an increase demand for advanced intracardiac imaging techniques of the left atrium and pulmonary veins. IVUS can demonstrate quantitative changes like lumen and wall thickness as well as qualitative changes of the pulmonary wall. IVUS could also provide relevant real time imaging of the atrial and pulmonary venous wall during catheter ablation. Areas covered: The Medline and Embase databases were searched for preclinical and clinical studies of IVUS in patients with ablation of atrial fibrillation or left atrial arrhythmias...

In Taiwan, In Vitro Diagnostic Medical Device (IVD) is regulated as medical device since 1987, and the implementation of IVD registration was fully completed in 2005. The management system of IVD medical device is highly similar with a guidance 'The GHTF Regulatory Model' developed by Global Harmonization Task Force (GHTF) in 2011 for use of regulation development on medical devices. Area covered: In this study, the Regulatory Model developed by GHTF was compared with Taiwanese IVD management system and it has shown that these two regulatory frameworks are highly similar...

Catheter based Interventional procedures have become an indispensable treatment option for patients contraindicated for surgical heart valve replacement . The broad spectrum of disease that affect the mitral valve have increased the need for a transcatheter mitral valve replacement (TMVR) device. As complex as the mitral valve anatomy is, so are challenges in the development of a TMVR device. Areas covered: This review article analyses the challenges in the development of the TMVR device from an engineering perspective of material and device design...

Non-invasive imaging plays a critical role in managing patients with cardiovascular disease. Although subjective visual interpretation remains the clinical mainstay, quantitative analysis facilitates objective, evidence-based management, and advances in clinical research. This has driven developments in computing and software tools aimed at achieving fully automated image processing and quantitative analysis. In parallel, machine learning techniques have been used to rapidly integrate large amounts of clinical and quantitative imaging data to provide highly personalized individual patient-based conclusions...

Hamed Vahedi, Asim M Makhdom, Javad Parvizi
Dual-mobility cups were introduced to reduce the incidence of dislocation after total hip arthroplasty (THA). The biomechanics of dual-mobility cups allow for greater range of motion, jump distance and better stability when compared to conventional cups in THA. These cups can be very beneficial in THA particularly when the hip instability is a concern such as elderly patients, obese, hip fracture patients, those with neuromuscular diseases, or patients undergoing revision THA for instability. Areas covered: An extensive search is conducted in PubMed and Google scholar to find past five years publications relevant to dual-mobility cups in THA...

Single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is well established as diagnostic test for patients with suspected or known coronary artery disease. New camera systems have been developed with cadmium-zinc-telluride (CZT) detectors, novel collimator designs and reconstruction software. Areas covered: We review the current state of cardiac SPECT, advances in conventional camera technology and the development and clinical validation of solid-state CZT cameras. Expert commentary: The development of CZT systems is timely and addresses current issues for clinical SPECT imaging...

The current standard of treatment for glaucoma is trabeculectomy. The use of glaucoma drainage devices has increased in recent years since its efficacy and safety was established as it provides an alternative surgical option. A downfall of these devices is the lack of proper flow rate control. Areas covered: In this paper we describe a glaucoma drainage device regulator that has already been protoyped and undergone initial testing. It consists of an implantable device with a semipermeable membrane that is used during glaucoma surgery and can be opened with either thermal or photodisruptive laser to adjust the amount of flow precisely and non-invasively, addressing the current difficulties of glaucoma surgeries...

An ideal treatment option for symptomatic Benign Prostatic Hyperplasia (BPH) should relieve lower urinary tract symptoms (LUTS) and restore Quality of Life (QoL). Currently available medical therapies and surgical options for symptomatic BPH have side effects that adversely affects quality of life. Prostatic urethral lift (PUL) is a novel endourology procedure that promises to relieve LUTS without the aforementioned side effects. Areas covered: We diligently reviewed all the published literature on PUL, till July 2016 using standard search criteria...

High-risk medical devices may not always provide a therapeutic added value to patients. In Europe, no proof of efficacy is required to receive a CE label, making it difficult for policymakers to decide on reimbursement of (often expensive) high-risk medical devices. We explore, within the framework of the European legislation, the possibilities at a national level for a guided introduction of such devices. Areas covered: HTA and legal experts worked in close collaboration with medical specialists and government representatives making a legal analysis of what is possible under the (revised) European and national legislation...
