BACKGROUND: The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). METHOD: Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS...

A 72-year-old man was admitted to our hospital because of dyspnea. He had a history of cardiac resynchronization therapy for congestive heart failure due to dilated cardiomyopathy 6 months previously. Echocardiography revealed severe functional mitral regurgitation which had been mild 6 months before. Because medical treatment was ineffective, on-pump beating mitral valve replacement using a bioprosthesis was performed to prevent reperfusion injury. The patient was easily weaned from cardiopulmonary bypass with low-dose inotropic support and scheduled intra-aortic balloon pump...

BACKGROUND: Symptomatic aortic stenosis has a poor prognosis. Many patients are considered inoperable or at high surgical risk for surgical aortic valve replacement (SAVR), reflecting their age, comorbidities and frailty. The clinical effectiveness and safety of TAVI have not been reviewed systematically for these high levels of surgical risk. This systematic review compares mortality and other important clinical outcomes up to 5 years post treatment following TAVI or other treatment in these risk groups...

OBJECTIVE:  Paravalvular leak (PVL) after valve replacement remains clinically challenging. Percutaneous closure is an effective therapy for patients with PVLs because reoperation is associated with high rates of morbidity and mortality. The purpose of this study was to retrospectively compare the clinical outcome of transcatheter closure and surgical repair in patients with a PVL. METHODS:  From January 2000 to May 2016, 131 patients with PVL were treated at three major medical centers in China...

In the United States, the octogenarian population is projected to triple by 2050. With this aging population, the prevalence of valvular heart disease (VHD) is on the rise. The etiology, approach to treatment, and expected outcomes of VHD are different in the elderly compared with younger patients. Both stenotic and regurgitant lesions are associated with unfavorable outcomes if left untreated. Surgical mortality remains high due to multiple co-morbidities, and long-term survival benefit is dependent on many variables including valvular pathology...

OBJECTIVES: Treatment of infants with tetralogy of Fallot (ToF) has evolved in the last two decades with increasing use of primary surgical repair (PrR) and transcatheter right ventricular outflow tract palliation (RVOTd), and fewer systemic-to-pulmonary shunts (SPS). We aim to report contemporary results using these treatment options in a comparative study. METHODS: This a retrospective study using data from the UK National Congenital Heart Disease Audit. All infants (n=1662, median age 181 days) with ToF and no other complex defects undergoing repair or palliation between 2000 and 2013 were considered...

The tissue-engineered heart valve may be the ideal valve replacement option but still must overcome challenges in leaflet recellularization. This study sought to investigate the potential for leaflet matrix restoration and repopulation following mononuclear cell seeding and extended periods of bioreactor conditioning. Human aortic heart valves were seeded with mononuclear cells and conditioned in a pulsatile bioreactor for 3 days, 3 weeks, or 6 weeks. The results of this study determined that a mononuclear cell population can be readily localized within the leaflet tissue in as little as 3 days...

Transcatheter aortic valve replacement in the setting of failed surgical bioprosthesis (valve-in-valve) is a valuable option for patients with bioprosthetic aortic stenosis or regurgitation who are deemed high risk for repeat open heart surgery. Although the procedure is successful with proper preprocedural assessment, instances of left main (LM) coronary artery ostium obstruction have been documented. We present a case of LM coronary obstruction in the immediate postoperative period following implantation of a 20-mm Edwards Sapien 3 valve inside the degenerated 21-mm Mitroflow bioprosthesis stenosis, which was treated with double stenting alongside the Edwards Sapien 3 valve creating a channel ("neo left main") that extended from mid-LM to the upper margin of the Edwards Sapien 3 valve...

Valvular heart disease is a major public health issue. The prevalence of valvular heart disease is expected to increase due to an aging population. Valve dysfunction manifests as valve stenosis, regurgitation, or both, due to various etiologies. Valve repair and replacement are the main treatment options for severe valve dysfunction. Valve replacement is achieved by using either a mechanical or a bioprosthetic valve. Mechanical valves are more durable but require lifelong anticoagulation with associated complications...

Valvular heart disease is an increasing population health problem and, especially in the elderly, a significant cause of morbidity and mortality. The current treatment options, such as mechanical and bioprosthetic heart valve replacements, have significant restrictions and limitations. Considering the increased life expectancy of our aging population, there is an urgent need for novel heart valve concepts that remain functional throughout life to prevent the need for reoperation. Heart valve tissue engineering aims to overcome these constraints by creating regenerative, self-repairing valve substitutes with life-long durability...

The tricuspid valve has long been described as the "forgotten valve", leaving tricuspid valve disease relatively neglected. However, the number of people in the United States affected by severe tricuspid regurgitation is growing. Isolated surgery for severe tricuspid regurgitation in the setting of right ventricular heart failure carries a high mortality risk, and therefore, attention to corrective therapies has increased. Because of the different etiologies for tricuspid regurgitation, multiple percutaneous transcatheter options for tricuspid valve repair for severe regurgitation are being studied and have been developed, including annuloplasty systems, leaflet and coaptation devices, vena caval (heterotopic) valve implantations, and tricuspid valve (orthotopic) replacement...

Background -Trans-catheter aortic valve replacement (TAVR) represents a paradigm shift in the therapeutic options for patients with severe aortic stenosis. However, rapid and exponential growth in TAVR demand may overwhelm capacity, translating to inadequate access and prolonged wait-times. Our objective was to evaluate temporal trends in TAVR wait-times and the associated clinical consequences. Methods -In this population-based study in Ontario, Canada, we identified all TAVR referrals from April 1st, 2010 to March 31st, 2016...

AIMS: TAVR implantation in unicuspid aortic valve has rarely been reported previously, due to the rareness of this morphology. This case tries to bring answers to some challenges we may have to face in TAVR current practice. METHODS AND RESULTS: We describe the case of a cardiogenic shock complicating a pure native regurgitating and non-calcified unicuspid aortic valve, in a 40 years old woman without medical follow up. Conventional treatment options such as valve surgery or heart transplantation were denied due to extreme operative risk and multiple allo-immunizations...
