AIMS: Mortality and left ventricular mass (LVM) recovery/regression after aortic valve replacement in patients with prosthesis-patient mismatch (PPM) is controversial. This study evaluated the impact of different values of indexed effective orifice area (EOAi) in male patients on mortality and indexed LVM (ILVM) recovery/regression. METHOD: The study recruited 376 male patients with and without PPM after aortic valve replacement with different EOAi cut-off values...

BACKGROUND: Treatment for patients with end-stage renal disease (ESRD) and severe aortic stenosis (AS) includes balloon aortic valvuloplasty (BAV), surgical (SAVR), or transcatheter (TAVR) aortic valve replacement. We compared outcomes among these strategies. METHODS: A retrospective review of patients with ESRD undergoing treatment for severe AS between 07/2007 and 06/2015 was performed at our center. Patients were classified based on treatment: BAV-only, TAVR, or SAVR...

BACKGROUND: Robotic mitral valve (MV) repair is the least invasive surgical approach to the MV and provides unparalleled access to the valve. We sought to assess technical aspects and clinical outcomes of robotic MV repair for isolated posterior leaflet prolapse by examining the first 623 such cases performed in a tertiary care center. METHODS: We reviewed the first 623 patients (mean age 56±9.7 years) with isolated posterior leaflet prolapse who underwent robotic primary MV repair from 01/2006 to 11/2013...

BACKGROUND: Mitral valve cleft (MVC) is the most common cause of congenital mitral insufficiency, and MVC may occur alone or in association with other congenital heart lesions. Direct suture and valvuloplasty are the major and effective treatments for mitral regurgitation (MR) caused by MVC. Therefore, it is important to determine the location and magnitude of the pathological damage due to MVC when selecting a surgical procedure for treatment. This study explored the application value of transthoracic real-time 3-dimensional (3D) echocardiography (RT-3DE) in the diagnosis of MVC...

Background Minimally invasive surgical access through limited sternotomy reduces trauma and morbidity in cardiosurgical patients. However, until now, it is not the standard access for aortic root replacement. This study details our clinic's experience with minimally invasive implantation of valved conduits through partial upper sternotomy and the comparison to conventional full median sternotomy. Methods Between January 2012 and March 2016, a total of 187 patients underwent aortic root replacement with valved conduits in our department...

BACKGROUND: Aortic aneurysm (AA) is one of the most common causes of sudden death among elderly people. Although AA can be detected by non-invasive imaging techniques, there are no pharmacological treatments currently available to prevent progression at any stage of the disease. In this study we will explore the expression of IKKε in AA and its potential underlying molecular mechanism in AA. Material s and methods: Human aortic tissue was taken from 14 patients who underwent surgical repair of AA for the AA group and another 11 patients with normal aorta who underwent aortic valve replacement surgery for the control group...

BACKGROUND: Permanent pacemaker (PPM) implantation after cardiac surgery is required in 0.4-6% of patients depending on cardiac surgery type. PPM implantation in the early postoperative period may reduce morbidity and postoperative hospital stay. We performed a retrospective review of electronic medical records of adult patients with coronary artery bypass grafting (CABG), valve surgery, or both, over a 3-year period. Our aim was to identify predictors of PPM requirements and PPM dependency on follow-up in the current surgical era...

The present study was conducted to characterize left intraventicular pressure gradients, a marker of normal cardiac function, in patients with severe aortic stenosis, a condition which interferes with ventricular filling and emptying. In 10 patients (4 male; mean age 71.3 ± 4.8 years old) undergoing aortic valve replacement, 2 high-fidelity pressure catheters were inserted inside the left ventricle cavity through an apical puncture and positioned in the apex and outflow-tract below the aortic valve. Pressures were continuously acquired and gradients were calculated as apical minus outflow-tract pressure, before and immediately after aortic valve replacement...

BACKGROUND AND AIM OF THE STUDY: The ascending aortic dilatation may progress after aortic valve replacement (AVR) in bicuspid aortic valve (BAV) patients. Our aim was to evaluate rheological flow patterns and histological characteristics of the aneurysmal aorta in BAV patients at the time of reoperative aortic surgery. MATERIALS AND METHODS: 13 patients (mean age: 42 ± 9 years, 10 (77%) male) with significant progression of proximal aortopathy after isolated AVR surgery for BAV disease (i...

AIMS: The prognostic impact of elevated pulmonary arterial pressure (PAP) remains controversial in aortic stenosis (AS) and few studies focused on patients with preserved left ventricular ejection fraction (LVEF). We aimed to investigate the impact of pulmonary hypertension (PH), invasively derived, on survival in severe AS with preserved LVEF. METHODS AND RESULTS: Between 2000 and 2010, 749 patients (74 ± 8 years, 57% males) with preserved LVEF and severe AS without other valvular heart disease underwent cardiac catheterization...

OBJECTIVE: Although the remodeling technique provides the most dynamic valve-sparing root replacement, a dilated annulus (>25 mm) is a risk factor for failure. Aortic annuloplasty aims to reduce the annulus diameter, thus increasing coaptation height to protect the repair. The results of 177 patients with remodeling and external aortic ring annuloplasty were studied. METHODS: Data were collected from the Aortic Valve repair InternATiOnal Registry. Preoperative aortic insufficiency grade 3 or greater was present in 79 patients (44...

OBJECTIVES: This study sought to evaluate this transcatheter aortic valve (TAV) bioprosthesis in patients who are poorly suitable for surgical aortic valve (AV) replacement. BACKGROUND: A novel self-expandable TAV bioprosthesis was designed to provide a low-profile delivery system, conformable annular sealing, and the ability to resheath and reposition during deployment. METHODS: The Evolut R U.S. study included 241 patients with severe aortic stenosis who were deemed to be at least high risk for surgery treated at 23 clinical sites in the United States...

Marie-Annick Clavel, Ian G Burwash, Philippe Pibarot
Up to 40% of patients with aortic stenosis (AS) harbor discordant Doppler-echocardiographic findings, the most common of which is the presence of a small aortic valve area (≤1.0 cm(2)) suggesting severe AS, but a low gradient (<40 mm Hg) suggesting nonsevere AS. The purpose of this paper is to present the role of multimodality imaging in the diagnostic and therapeutic management of this challenging entity referred to as low-gradient AS. Doppler-echocardiography is critical to determine the subtype of low-gradient AS: that is, classical low-flow, paradoxical low-flow, or normal-flow...

PURPOSE OF REVIEW: This focused review summarizes key insights from the past 12 months of basic science and clinical research on bicuspid aortic valve (BAV)-associated aortopathy. RECENT FINDINGS: Recent studies in BAV-associated aortopathy support a heterogeneous spectrum of disease with distinct phenotypes. Basic science studies provide further support for the concept of regional differences in the severity of aortopathy within the aorta of BAV patients. Clinical studies compared outcomes of BAV patients after isolated aortic valve replacement and showed that those with primarily valvular insufficiency as compared with stenosis may be at greater risk for important aortic events over time...

BACKGROUND: There is discordance regarding the effect of symptom status before aortic valve replacement (AVR) on long-term outcome after AVR in severe aortic stenosis (AS).Methods and Results:The CURRENT AS registry is a multicenter retrospective registry enrolling 3,815 consecutive patients with severe AS. Among 1,196 patients managed with the initial AVR strategy, long-term clinical outcomes were compared between the symptomatic patients (n=905), and asymptomatic patients (n=291)...
