PURPOSE OF REVIEW: With widespread adoption of transcatheter aortic valve replacement, there has been a change in the approach to management of valvular heart disease. New interest has taken hold in transcatheter therapies for valvular heart disease, as well as research into pathophysiology and progression of disease. Additionally, several key trials have further refined our understanding of surgical management of valvular heart disease. This review will elucidate recent clinical trial data leading to changes in practice...

BACKGROUND: Little is known about patients with severe symptomatic aortic stenosis (AS) who receive medical management despite evaluation at a heart valve treatment center. OBJECTIVE: We identified patient characteristics associated with medical management, physician-reported reasons for selecting medical management, and patients' perceptions of their involvement and satisfaction with treatment selection. METHODS AND RESULTS: Of 454 patients evaluated for AS at 9 established heart valve treatment centers from December 12, 2013 to August 19, 2014, we included 407 with severe symptomatic AS...

BACKGROUND: Aortic valve disease is a common condition that is easily treatable with cardiac surgery. This is conventionally performed by opening the sternum longitudinally down the centre ("median sternotomy") and replacing the valve under cardiopulmonary bypass. Median sternotomy is generally well tolerated, but as less invasive options have become available, the efficacy of limited incisions has been called into question. In particular, the effects of reducing the visibility and surgical access has raised safety concerns with regards to the placement of cannulae, venting of the heart, epicardial wire placement, and de-airing of the heart at the end of the procedure...

INTRODUCTION: Rheumatic mitral stenosis is the most common Valvular Heart Disease encountered during pregnancy. Balloon Mitral Valvuloplasty (BMV) is one of the treatment option available if the symptoms are refractory to the medical management and the valve anatomy is suitable for balloon dilatation. BMV with Inoue balloon is the most common technique being followed worldwide. Over the wire BMV is a modified technique using Joseph Mitral Valvuloplasty (JOMIVA) balloon catheter which is being followed in certain centres...

A 68 year-old man with a severe ischemic cardiomyopathy underwent left ventricular assist device (LVAD) implantation (Heart Mate II device) for destination therapy. He presented 49 months following LVAD implant with worsening heart failure symptoms and new severe aortic regurgitation. Given high risk for both surgical and transcatheter aortic valve replacement, he was admitted for transcatheter closure of the aortic valve under transesophageal echocardiographic (TEE) guidance. TEE imaging revealed severe aortic regurgitation (see Figure 1A and 1B, and multimedia files 1 and 2)...

Apicoaortic conduit surgery is an option for treating severe aortic stenosis. The implanted conduit valve may eventually fail and require replacement; this is usually performed by repeat surgery. Treating the conduit valve with a standard transcatheter heart valve is an option that has become feasible in recent years. We describe a case of a failed 23 mm CE bioprosthesis that was successfully treated with a 23 mm Sapien XT valve as a valve-in-valve procedure. © 2017 Wiley Periodicals, Inc.

BACKGROUND: Following publication of the results of the PARTNER trial, the American College of Cardiology/American Heart Association recognized the success of transcatheter aortic valve replacement (TAVR) by incorporating it as a feasible option in high-surgical risk patients, and recommending it as the standard of care for patients at prohibitive risk of surgery. Although this was recognized as a major success in the field of percutaneous valve replacement, surgical aortic valve replacement (SAVR) continued to be realized as the procedure of choice for low and intermediate surgical risk patients...

Cardiovascular disease is the leading cause of mortality worldwide. We have made large strides over the past few decades in management, but definitive therapeutic options to address this health-care burden are still limited. Given the ever-increasing need, much effort has been spent creating engineered tissue to replaced diseased tissue. This article gives a general overview of this work as it pertains to the development of great vessels, myocardium, and heart valves. In each area, we focus on currently studied methods, limitations, and areas for future study...

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...

BACKGROUND: Transcatheter tricuspid VIV replacement has been proposed as a feasible option for high-risk patients with previous tricuspid valve replacement that undergo valve degeneration causing refractory heart failure. However, little is known about the long-term outcome of patients treated with transcatheter tricuspid VIV. We evaluate the safety of transcatheter tricuspid valve-in-valve (VIV) replacement by using balloon-expandable aortic valve stents and the long-term follow-up. METHODS AND RESULTS: From January 2013 to March 2016, 4 patients underwent transcatheter tricuspid VIV in our center using balloon-expandable Edwards Sapien-XT and Sapien-3 valves...

The optimal decision regarding whether to repair or replace the tricuspid valve (TV) remains controversial in patients with very severe functional tricuspid regurgitation (TR). We sought to compare clinical outcomes of TV repair versus replacement for very severe TR associated with severe TV tethering. We included 96 consecutive patients (20 men, 58 ± 11 years of age) who had both severe tethering of TV and very severe functional TR and consequently underwent TV surgery during left-sided valve surgery. TV repair was performed on 79 patients (repair group), whereas 17 patients underwent TV replacement (replacement group)...

Human heart valve allografts continue to represent almost perfect substitutes for heart valves. They have optimal hemodynamic characteristics and are highly resistant to infections. The first clinical use of allograft heart valves was as homovitals being transplanted after antibiotic incubation without any preservation. Since 1968, relatively standardized frozen cryopreservation (SFC) has been employed, including storage in vapor-phase liquid nitrogen. Disadvantages, particularly in pediatric patients, are limited availability due to organ scarcity, inability to grow, degeneration, immune response, and long-term failure...

Sutureless aortic valve replacement (AVR) was developed as an alternative treatment option to conventional open-heart surgery and transcatheter aortic valve implantation for "gray zone" patients. The need for concurrent mitral valve surgery is generally viewed as a contraindication to sutureless AVR. The purpose of this brief paper is to report our experiences with sutureless valves in patients after previous cardiac procedures with degenerated aortic bioprostheses and concomitant mitral valve disease.
