Minimally invasive aortic valve replacement (mini-AVR) procedures are a valuable alternative to conventional open heart surgery. Currently, planning of mini-AVR consists of selection of the intercostal space closest to the sinotubular junction on preoperative computer tomography images. We developed an automated algorithm detecting the sinotubular junction (STJ) and intercostal spaces for finding the optimal incision location. The accuracy of the STJ detection was assessed by comparison with manual delineation by measuring the Euclidean distance between the manually and automatically detected points...

BACKGROUND: The risk of permanent pacemaker implantation (PPI) after cardiac valve replacement surgery is thought be highest in the post-operative period. Long-term risks are uncertain. OBJECTIVE: To determine rates and timing of PPI after valve replacement surgery. METHODS: We compared PPI rates patients undergoing aortic (AVR, n = 111,674), mitral (MVR, n = 18,402) valve replacement, AVR+MVR (n = 5,166) or AVR + MVR and tricuspid valve replacement (TVR, n = 114) or CABG without valve replacement (n=249,742)...

BACKGROUND: Accurate assessment of Cardiac Output (CO) is a critical measurement in the calculation of aortic valve area (AVA). Due to the known inaccuracy of estimated Fick calculations, many measure thermodilution (TD) CO as well due to previous studies showing better correlation with the gold standard direct CO. Previous studies showed suboptimal correlation between both methods. Most physicians assume that the TD CO is chosen by catheterization laboratory software for AVA evaluation...

A 40-year-old man with osteogenesis imperfecta type I submitted to multiple procedures of surgical mitral and aortic valve replacement was referred for refractory congestive heart failure due to significant paravalvular leaks (PVLs) of both mitral and aortic prostheses. Due to perceived very high risk of a further mitroaortic surgery, transcatheter closure of PVLs under three-dimensional echocardiographic guide was performed. Thus, four Amplatzer Vascular Plug type II (St. Jude Medical Corp, St. Paul, Minnesota, USA) devices were implanted into the aortic PVLs, and three Amplatzer Vascular Plug type II devices were used to occlude a huge mitral PVL...

Cardiovascular diseases continue to be a major cause of mortality and morbidity in the world population. First open heart procedure was performed by Gibbon in 1953, since then many advancements have been introduced to the field of cardiac surgery. Minimally invasive techniques were introduced, which include minimally invasive coronary artery bypass grafting (CABG), off-pump technique, minimally invasive valve surgery or transcatheter techniques to implant stentless or sutureless valves. The hybrid strategy to address coronary disease combines catheterisation procedures with standard surgical techniques...

BACKGROUND: Cardiac rehabilitation (CR) is an evidence-based intervention to increase survival and quality of life. Yet studies consistently show that elderly patients are less frequently referred to CR, show less uptake and more often drop out of CR programmes. DESIGN: The European study on effectiveness and sustainability of current cardiac rehabilitation programmes in the elderly (EU-CaRE) project consists of an observational study and an open prospective, investigator-initiated multicentre randomised controlled trial (RCT) involving mobile telemonitoring guided CR (mCR)...

A woman aged 36 years G2P1 presented at our outpatient clinic with symptoms of discomfort, dyspnoea and fever at a gestational age of 17 weeks. She was subsequently diagnosed with severe endocarditis with a large vegetation on the mitral valve. She underwent open chest mitral valve surgery while on cardiopulmonary bypass (CPB) within a few days. Such surgical intervention is not only associated with increased maternal risks, but also with severe fetal morbidity and mortality. In such patients, certain perioperative measures can diminish these risks...

Aortocoronary bypass or valve surgery usually require cardiac arrest using cardioplegic solutions. Although, in principle, in a number of cases beating heart surgery (so-called off-pump technique) is possible, aortic or valve surgery or correction of congenital heart diseases mostly require cardiopulmonary arrest. During this condition, the heart-lung machine also named cardiopulmonary bypass (CPB) has to take over the circulation. It is noteworthy that the invention of a machine bypassing the heart and lungs enabled complex cardiac operations, but possible negative effects of the CPB on other organs, especially the brain, cannot be neglected...

BACKGROUND: The role of percutaneous mitral valve repair (PMVR) in patients with end-stage heart failure (HF) and functional mitral regurgitation (FMR) is unclear. METHODS: Seventy-five consecutive patients with FMR grade≥3+ and severe HF symptoms despite optimal medical therapy and resynchronization therapy underwent PMVR with the MitraClip system (Abbott, Abbott Park, IL, USA) at 3 centers. Clinical evaluation, echocardiography and pro-BNP measurement were performed at baseline and at 6-month...

Surgical aortic valve replacement is the most common procedure of choice for the treatment of severe aortic stenosis. Bioprosthetic valves are traditionally sewed-in the aortic root by means of pledget-armed sutures during open-heart surgery. Recently, novel bioprostheses which include a stent-based anchoring system have been introduced to allow rapid implantation, therefore reducing the duration and invasiveness of the intervention. Different effects on the hemodynamics were clinically reported associated with the two technologies...

Aortic stenosis is one the most frequent valvular diseases in developed countries, and its impact on public healthcare resources and assistance is increasing. A substantial proportion of elderly patients with severe aortic stenosis is frequently not eligible for surgery because of advanced age, frailty and multiple comorbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy...

BACKGROUND: The ACC/AHA guidelines introduced a new classification of severe aortic stenosis (AS) mainly based on maximum jet velocity (Vmax) and mean pressure gradient (mPG), but not on aortic valve area (AVA). However, prognostic value of this new classification has not yet been fully evaluated. METHODS AND RESULTS: We studied 1512 patients with asymptomatic severe AS enrolled in the CURRENT AS registry in whom surgery was not initially planned. Patients were divided into 2 groups: Group 1 (N=122) comprised patients who met the recommendation for surgery; high-gradient (HG)-AS (Vmax≥4...

Mitraclip(®) implantation is widely used as a valid alternative to conventional open-chest surgery in high-risk patients with severe mitral valve (MV) regurgitation. Although effective in reducing mitral regurgitation (MR) in the majority of cases, the clip implantation produces a double-orifice area that can result in altered MV biomechanics, particularly in term of hemodynamics and mechanical stress distribution on the leaflets. In this scenario, we combined the consistency of in vitro experimental platforms with the versatility of numerical simulations to investigate clip impact on MV functioning...

BACKGROUND: Preoperative hemoglobin A1c (HbA1c) and postoperative glycemic variability predict major adverse events (MAEs) after coronary artery bypass grafting in a protocolized glycemic control setting. However, the influence of preoperative HbA1c and postoperative glycemic variability in isolated cardiac valvular surgery is unknown. In this study, we sought to establish (a) whether preoperative HbA1c could identify patients at increased risk of MAEs and (b) whether postoperative glycemic variability was associated with MAEs after isolated cardiac valvular surgery...

This investigation sought to determine the feasibility of a novel mitral ring designed to reshape mitral annulus on beating heart, after surgery. The mitral ring is intended to improve mitral leaflets coaptation to correct residual and recurrent mitral regurgitations. It could also provide progressive correction of mitral regurgitation. The device was tested in ex vivo beating heart model.The novel mitral ring is selectively deformable in P1, P2 and P3 segments using a dedicated angioplasty-type balloon. The deformation should increase leaflets' coaptation reducing distance between the two leaflets...

BACKGROUND: Severe primary mitral regurgitation (MR) carries a significant incidence of mortality and morbidity. Though a number of prognostic factors have been identified, the best timing for mitral valve repair is still debated. We assessed the role of Left Atrial Volume Indexed (LAVI) as predictor of adverse events after mitral valve surgery. METHODS: 134 patients with severe MR were studied with a follow-up of 42±16months. Endpoints were Post-Operative Atrial Fibrillation (POAF), atrial and ventricular remodeling (LARR/LVRR) and correlation with outcome...
