Transcatheter mitral valve replacement with the Tiara valve can be performed in inoperable patients with severe functional regurgitation. Risk of left ventricular outflow tract obstruction can be prevented using preoperative 3D imaging and 3D-printed models. However, in the case of mono-disk mechanical prostheses previously implanted in aortic position (Bjork-Shiley), there is an additional risk of mechanical interference leading to reduced leaflet motion and aortic valve dysfunction. Hereafter, we describe the case of a patient with a 27-mm mono-disk mechanical aortic valve implanted in 1978, a EuroSCORE II of 18%, and a Society of Thoracic Surgeon score (mortality) of 16% who successfully underwent a transapical Tiara valve implantation...

The rise of antibiotic resistant bacteria is posing a serious threat to human health. For example, resistant strains of Pseudomonas aeruginosa have resulted in untreatable and potentially lethal infections in both cystic fibrosis and immunocompromised patients. Due to the growing need for alternative treatment options, bacteriophage, or phage, therapy is gaining considerable attention. While previous studies have demonstrated the effectiveness of phage in combating persistent bacterial infections, there is currently a lack of knowledge regarding the host immunological response following phage exposure...

BACKGROUND: Flexible bronchoscopy (FB) is commonly performed to assess, diagnose, and treat patients with respiratory disease, and is typically performed via transnasal or transoral approaches. FB can be performed via tracheal tubes in patients with tracheostomies; however, the safety and technical feasibility has not been established. The present study evaluates the safety and feasibility of performing FB via tracheal tubes. MATERIALS AND METHODS: A total of 45 patients underwent 56 procedures involving FB via tracheal tubes at a single institution from November 2013 to November 2014 and were included in this retrospective case series...

A case of influenza-associated acute necrotizing encephalitis (ANE) is described in an otherwise healthy adult. The patient was treated successfully with a combination of high-dose methylprednisolone and high-dose oseltamivir. The patient relapsed after discontinuing 150 mg twice daily oseltamivir but quickly improved and eventually recovered after reinitiation of high-dose oseltamivir for an additional 2 weeks. The clinical presentation, pathogenesis, and treatment of influenza-associated ANE is reviewed. The use of high-dose oseltamivir in combination with methylprednisolone may offer additional therapeutic benefit for this rare and poorly understood complication of influenza infection...

OBJECTIVE: Determine the effects of household dishwashing on Tracheostomy Tube safety. INTRODUCTION: Tracheostomy tubes accumulate biofilms, which may limit their lifespan. Frequent cleaning of the tubes is a method for biofilm prevention. Cleaning practices vary widely. Some families prefer dishwashing of tubes, but its effects are currently unknown. We hypothesize that dishwashing has no significant effect on the physical properties of tracheostomy tubes and can be recommended as a safe way to clean tracheostomy tubes...

Mechanical heart valves have been used worldwide for more than 60 years. While the composition and design of the valves, and the surgical techniques employed to implant them, have changed and advanced over that time, some of the earlier mechanical heart valves showed such great durability that they are still functioning in patients today. One of the most often-used and long-lasting mechanical prostheses was the Björk-Shiley heart valve. While many versions of this valve were used during its 25 years of production, the most durable was the Björk-Shiley flat-disc valve...

Laryngeal masks are invasive devices for airway management placed in the supraglottic position. The Shiley™ laryngeal mask (Shiley™ LM) features an integrated inflation tube and airway shaft to facilitate product insertion and reduce the chance of tube occlusion when patients bite down. This study compared the Shiley LM to two other disposable laryngeal mask devices, the Ambu(®) AuraStraight™ and the LMA Unique™. Overall device design, tensile strength, flexibility of various structures, and sealing performance were measured...

A patient who underwent previous implantation of a mitral valve replacement with a Björk-Shiley Delrin (BSD) mitral valve prosthesis during infancy was admitted to our institution 43 years later after an episode of syncope and cardiac arrest. Under extreme hemodynamic instability, a mitral valve prosthetic dysfunction causing massive mitral regurgitation was identified. The patient underwent an emergent cardiac operation, and a complete disc fracture with partial disc migration was found. Exceptional cases of mechanical prosthetic heart valve fracture exist...

Although Plesiomonas shigelloides, a water-borne bacterium of the Enterobacteriaceae family, usually causes self-limiting gastroenteritis with diarrhea, several cases of sepsis have been reported. We report the case of a 43-year-old male patient with hemochromatosis, pyruvate kinase deficiency, and asplenia via splenectomy who developed septic shock caused by P. shigelloides complicated by respiratory failure, renal failure, liver failure, and disseminated intravascular coagulation. Early aggressive antimicrobial therapy and resuscitation measures were unsuccessful and the patient passed away...

Prosthetic valve fracture is a serious complication and may arise in patient post-valve replacement. We experienced an outlet strut fracture and leaflet escape of a Bjork-Shiley convexo-concave valve. We performed an emergency redo mitral valve replacement and successfully retrieved the fractured strut and escaped leaflet from superficial femoral artery and the abdominal aorta. The patient showed an uneventful postoperative recovery.

BACKGROUND: The optimal choice for pulmonary valve replacement (PVR) remains controversial. This study hypothesized that xenografts used for PVR would result in prolonged long-term survival and freedom from reoperation. METHODS: Children and adults with congenital heart disease requiring PVR using a xenograft from 1980 to 1985 were reviewed. In all cases, the xenograft valve was either sewn or manufactured into a Dacron conduit, and the conduit was sewn to the pulmonary artery bifurcation...

The Bjork Shiley valve (BSV) is considered as the pioneer among modern disc valves, and eventually evolved into a reliable prosthesis after considerable research and multiple modifications. Various case reports have been published with follow-up of different types of BSV. We are reporting the longest follow-up ever published of a plano-convex type of BSV. Our patient's valve was implanted in 1973 due to a congenital bicuspid aortic valve with concomitant severe, symptomatic aortic stenosis, discovered at the age of 27...

INTRODUCTION: The Shiley™ Flexible adult tracheostomy tube with TaperGuard™ cuff has been designed through its geometry, materials, diameter, and wall thickness to minimize micro-aspiration of fluids past the cuff and to provide an effective air seal in the trachea while also minimizing the risk of excessive contact pressure on the tracheal mucosa. The cuff also has a deflated profile that may allow for easier insertion through the stoma site. This unique design is known as the TaperGuard™ cuff...

The implanted prosthetic heart valve (PHV) size is vital for the evaluation of suspected PHV dysfunction and in case of reoperation or valve-in-valve transcatheter approaches. The labeled size is not always known, and discrepancies exist between manufacturers' labeled sizes and true sizes. Reproducible methods for noninvasive PHV size assessment are lacking. We determined the reliability and agreement of PHV size measurements using multidetector-row computed tomography (MDCT) and provide reference values of MDCT measurements compared with manufacturer specifications...

The implanted first-generation Björk-Shiley valve in our patient was functioning well before aortic surgery, but we replaced the valve because we confirmed disc erosion 39 years after implantation during the surgery. We judged that the implanted valve was no longer capable of maintaining the patient's life.
