BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an alternative for surgically inoperable patients with severe aortic stenosis. Advanced kidney disease may significantly affect outcomes in patients treated with TAVR and surgical aortic valve replacement (SAVR). HYPOTHESIS: TAVR is associated with better in-hospital outcomes compared with SAVR in patients with advanced kidney disease. METHODS: We identified our sample from the National Inpatient Sample between 2012 and 2014, using International Classification of Diseases, Ninth Revision, Clinical Modification codes...

BACKGROUND: Stentless aortic valves have been developed to overcome obstructive limitations associated with stented bioprostheses. A new concept of surgical sutureless (SU) bioprosthesis has been developed in the last decade. In this multi-institutional study we sought to compare hemodynamics of different bioprosthesis concept as transcatheter (TAVR), Livanova Perceval S sutureless valve and Freedom Solo Stentless (FS) valve in patients undergoing aortic valve replacement (sAVR). METHODS: From 2010 to 2016, 478 patients underwent sAVR with FS, 518 Perceval S and 367 patients underwent TAVR...

A new controversy is raising in cardiovascular surgery, whether or not the new generation transcatheter valves used for valve implantation are superior to surgical techniques used for traditional valve replacement. If such a debate is far from being an issue for mitral valve treatment, where minimal invasive, (robotic or video-assisted) mitral valve repair has become the gold standard for mitral valve treatment while transcatheter mitral valve solutions are lagging behind(1-4), there are many voices stating that the future of aortic valve treatment will mainly be transcatheter(5)...

Tricuspid regurgitation (TR) is a common entity, most commonly functional in nature due to right-sided dysfunction in the setting of concomitant cardiac disease or pulmonary hypertension. Patients living with TR often experience numerous limitations as a result of right-sided heart failure symptoms, including functional decline, frequent hospitalizations, liver failure, and kidney failure. Furthermore, patients with significant TR demonstrate worse survival, although a cause-and-effect relationship has not been proven...

Surgical aortic valve replacement (SAVR) in patients with porcelain aorta is considered a high-risk procedure. Hence, transcatheter aortic valve implantation (TAVI) is emerging as the intervention of choice. However, there is a paucity of data directly comparing TAVI with SAVR in patients with porcelain aorta. We compared outcomes of TAVI versus SAVR in high-risk patients with porcelain between March 2012 and June 2015. The TAVI group included 54 patients, whereas 130 SAVR patients with porcelain aorta were identified (operated on between 2004 and 2015)...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a less invasive treatment for elderly patients with aortic stenosis. However, the cost of TAVI is a major issue. This study analyzed the cost effectiveness of TAVI in Japan. METHODS: We developed an economic model to evaluate the quality-adjusted life years (QALYs) and costs of TAVI, surgical aortic valve replacement (SAVR), and medical therapy over a 10-year time horizon from the perspective of Japanese public healthcare payers...

INTRODUCTION: Aortic stenosis is the most prevalent type of valvular disease in Europe. Surgical aortic valve replacement (SAVR) is the standard therapy, while transcatheter aortic valve implantation (TAVI) is an alternative in patients at unacceptably high surgical risk. Assessment by a heart team is recommended by the guidelines but there is little published evidence on this subject. The purpose of this paper is to describe the experience of a multidisciplinary TAVI program that began in 2008...

OBJECTIVES: The goal of this study was to explore sex differences in myocardial remodeling in aortic stenosis (AS) by using echocardiography, cardiac magnetic resonance (CMR), and biomarkers. BACKGROUND: AS is a disease of both valve and left ventricle (LV). Sex differences in LV remodeling are reported in AS and may play a role in disease phenotyping. METHODS: This study was a prospective assessment of patients awaiting surgical valve replacement for severe AS using echocardiography, the 6-min walking test, biomarkers (high-sensitivity troponin T and N-terminal pro-brain natriuretic peptide), and CMR with late gadolinium enhancement and extracellular volume fraction, which dichotomizes the myocardium into matrix and cell volumes...

Calcific aortic valve disease (CAVD) is the most frequent cardiac valve pathology. Its standard treatment consists of surgical replacement either with mechanical (metal made) or biological (animal tissue made) valve prostheses, both of which have glaring deficiencies. In the search for novel materials to manufacture artificial valve tissue, we have conducted a high-throughput screening with subsequent up-scaling to identify non-degradable polymer substrates that promote valve interstitial cells (VICs) adherence/growth and, at the same time, prevent their evolution toward a pro-calcific phenotype...

A 74-year-old male presented to the emergency department 46 days after undergoing an aortic valve replacement. He presented with nonspecific symptoms developed over the previous 15 days, with a new onset of a systolic panfocal murmur. Echocardiography revealed a great vegetation measuring 15 mm by 23 mm causing a severe obstruction of the bioprosthesis. The patient underwent an emergency surgical procedure due to his hemodynamic unsteadiness. During the procedure, we noted an obstruction of the left ventricle outflow tract with pseudoaneurysm of the aortomitral continuity...

BACKGROUND: Sutureless aortic valve prostheses have the potential to augment the adoption of alternative incision approaches for aortic valve replacement (AVR). Still, we lack the evidence on which surgical approach is best associated with sutureless AVR. METHODS: Data on 483 patients undergoing sutureless small incision AVR between 2010-2014 in two European institutions (207 with partial sternotomy (MS) and 276 via right anterior minithoracotomy (RAMT)) have been retrospectively analyzed...

BACKGROUND: Type 2 diabetes mellitus (T2DM) is strongly related to the in-hospital and short-term prognosis in patients with cardiovascular diseases needing surgical or invasive interventions. How T2DM might influence the treatment of aortic stenosis (AS) has not been completely elucidated for surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI). The aims of this study were: (1) to describe the use of aortic valve replacement procedures (TAVI and SAVR) among hospitalized patients with and without T2DM; and (2) to identify factors associated with in hospital mortality (IHM) among patients undergoing these procedures...

BACKGROUND: The prevalence of congenital heart disease (CHD) in the adult population is steadily increasing. A substrate of prosthetic material and residual lesions, constantly evolving as surgical techniques change over time, predispose these patients to the potentially devastating complication of infective endocarditis (IE). METHODS: We retrospectively reviewed 2935 patients in our adult CHD database for all cases of endocarditis between 1991 and 2016. Incidence, clinical course and predictors of outcomes were analysed...

Aortic stenosis (AS) is the most common form of valvular heart disease. A detailed diagnostic workup is necessary to promptly stage and classify disease severity to determine the optimal management. Medical therapy and valvuloplasty are options that fail to delay or reverse disease progression. Surgical aortic valve replacement (SAVR) is curative but has significant limitations for some patient populations. A newer option, transcatheter aortic valve replacement (TAVR), has become more widely available to patients with intermediate- or high-operative risk...

Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with failing bioprosthetic valves with high surgical risk due to concomitant comorbidities. We performed 2 transapical ViV procedures for failing mitral bioprosthetic valves, 1 transfemoral procedure for failing pulmonary valve and 2 transfemoral ViV implantation for failing tricuspid bioprosthetic valves...
