OBJECTIVES: Mitral periprosthetic leakage (PPL) is a serious complication following valve replacement. Conflicting outcomes of surgical treatment have been reported in the presence of multiple previous cardiac operations and associated co-pathological conditions. METHODS: Sixty-five symptomatic patients (37 women, mean age 64.8 years) underwent conventional operations at our hospital from 2006 to 2015. Mitral PPL was the leading surgical indication, although associated procedures were included...

OBJECTIVES: Combined coronary artery bypass grafting and valve surgery requires a prolonged period of cardioplegic arrest (CA) predisposing to myocardial injury and postoperative cardiac-specific complications. The aim of this trial was to reduce the CA time in patients undergoing combined coronary artery bypass grafting and valve surgery and assess if this was associated with less myocardial injury and related complications. METHODS: Participants were randomized to (i) coronary artery bypass grafting performed on the beating heart with cardiopulmonary bypass support followed by CA for the valve procedure (hybrid) or (ii) both procedures under CA (conventional)...

OBJECTIVES: A transcatheter heart valve technique can be used in failed mitral valve repairs with annuloplasty rings, deterioriated bioprostheses and in mitral annular calcification, all serving as 'docking stations' for balloon-expandable valves. Specially designed transcatheter mitral valve platforms are used in ongoing studies for native mitral valve regurgitation. We present our single centre experience with transcatheter mitral valve implantation-transapical approach procedures in eleven patients...

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 The use of cardiac magnetic resonance imaging is increasing, but its role in the diagnostic work-up following ischemic stroke has received limited study. We aimed to explore the added yield of cardiac magnetic resonance imaging to identify cardio-aortic sources not detected by transesophageal echocardiography among patients with cryptogenic stroke. Methods A retrospective single-center cohort study was performed from 01 January 2009 to 01 March 2013. Consecutive patients who had both a stroke protocol cardiac magnetic resonance imaging and a transesophageal echocardiography preformed during a single hospitalization were included...

OBJECTIVE: Transitions in the spectrum of valvular heart diseases (VHDs) in developed countries over the 20th century have been reported from clinical case series, but large, contemporary population-based studies are lacking. METHODS: We used nationwide registers to identify all patients with a first diagnosis of VHD at Swedish hospitals between 2003 and 2010. Age-stratified and sex-stratified incidence of each VHD and adjusted comorbidity profiles were assessed...

Missile embolus to the heart, although uncommon, is one of the most challenging scenarios in trauma. We describe a 36-year-old man who presented with a gunshot wound to the left chest and a chest x-ray revealing a foreign body in the mediastinum. A median sternotomy was performed and an injury to the left ventricle was identified. After intraoperative echocardiography and fluoroscopy confirmed a foreign body in the aortic root, cardiopulmonary bypass was implemented. A bullet was retrieved from the noncoronary sinus of the aortic valve...

We present a rare case of mitral regurgitation with anterior mitral leaflet perforation associated with gelatin-resorcinol-formaldehyde (GRF) glue. We performed mitral valve replacement for anterior mitral leaflet perforation occurred 7 years after aortic valve replacement and abscess cavity repair using GRF glue. Long-term follow-up is needed for patients who have undergone surgeries using GRF glue or BioGlue (CryoLife, Inc, Kennesaw, GA) because of the possibility of late complications. In particular, when an eccentric mitral regurgitation is observed after aortic root surgery using GRF glue or BioGlue, anterior mitral leaflet perforation should be considered...

OBJECTIVES: This study was designed to establish clinical outcomes after aortic valve replacement (AVR) with On-X bileaflet mechanical heart valve. METHODS: Between 2006 and 2014, AVR was performed to 686 patients. Of them, 78 patients using On-X valve were enrolled. The mean age was 65 ± 11 years (ranged 33-85); 65% were men; and 81% were in sinus rhythm preoperatively. Calcific or degenerative tricuspid aortic valve was present in 73%. Concomitant procedures included coronary artery bypass grafting (22%), Bentall (8%), mitral valve procedure (3%) and other (9%)...

Scientific progress shall ultimately boost the current acceptance level for conservative aortic valve surgery. The present text aimed to report the 23-year long-term follow-up of one patient operated with bovine pericardium cusp extension. Growing confidence in the efficacy of the operation will allow a more expeditious indication for surgical treatment, as is already the case in mitral valve repair. This change of attitude will certainly make it possible for patients to be sent for operation in mild aortic valve regurgitation...

A 79-year-old man with history of aortic stenosis, status post bioprosthetic aortic valve replacement, episodes of bacteremia, and endocarditis presented to hospital with fever. Clinical assessment led to suspicion of possible endocarditis. Initial interpretation of transesophageal echocardiogram was inconclusive without vegetation in mitral/aortic valve. An In-leukocyte scan demonstrated increased uptake in the area of aortic valve, suggestive of infection. Further review of the transesophageal echocardiogram showed signs of annular abscess...

Background: The closure of the valves generates shear waves in the heart walls. The propagation velocity of shear waves relates to stiffness. This could potentially be used to estimate the stiffness of the myocardium, with huge potential implications in pathologies characterized by a deterioration of the diastolic properties of the left ventricle. In an earlier phantom study we already validated shear wave tracking with a clinical ultrasound system in cardiac mode. Purpose: In this study we aimed to measure the shear waves velocity in normal individuals...

Background: Mitral valve resistance (MVR) is a hemodynamic consequence of mitral stenosis but it has no clear threshold and it has a shortage of data to be reliable. Purpose: is to investigate match and mismatch between opening area and resistance especially in patients with moderate and mild mitral stenosis. Materials: This cross section case control study comprised 88 patients with moderate and mild rheumatic mitral stenosis. Transthorathic echocardiographic study estimated: mitral valve area (MVA) both by planimerty (2D) and pressure half time (PHT), mitral valve score (MVS), mean transmitral pressure gradient (MPG), diastolic filling time(DFT), left ventricular out flow tract diameter (LVOTd) and velocity time integral (LVOT vti) , the MVR was calculated as: MPG/aortic flow ratio [(LVOTd) (LVOTvti)/ DFT] in dynes...

Aims. The Assessment of left ventricular (LV) function remains a clinical challenge especially in patients with preserved LV ejection fraction (EF) and valvular heart diseases (VHD). Mechanical dispersion is supposed to be a strong predictor of events and, to be related to the extent of fibrosis. Regional cardiac work is a new validated and very promising approach to quantify LV-function. We investigated the differences in mechanical dispersions and global LV work (totW) and wasted work fraction (WWF) in normal subjects and in patients with severe primary mitral regurgitation (MR) and severe aortic stenosis (AS)...

OBJECTIVE: We aimed to define the normal range of aortic and mitral valve thickness in healthy schoolchildren from a high prevalence rheumatic heart disease (RHD) region, using a standardised protocol for imaging and measurement. METHODS: Measurements were performed in 288 children without RHD. Anterior mitral valve leaflet (AMVL) thickness measurements were performed at the midpoint and tip of the leaflet in the parasternal long axis (PSLA) in diastole, when the AMVL was approximately parallel to the ventricular septum...

For the year 2016, more than 20,000 published references can be found in Pubmed when entering the search term "cardiac surgery". Publications last year have helped to more clearly delineate the fields where classic surgery and modern interventional techniques overlap. The field of coronary bypass surgery (partially compared to percutaneous coronary intervention) was enriched by five large prospective randomized trials. The value of CABG for complex coronary disease was reconfirmed and for less complex main stem lesions, PCI was found potentially equal...

AIMS: To identify the impact of previous aortic valve replacement (AVR) in Mitra-Clip (MC) patients. METHODS AND RESULTS: Data from the German Transcatheter Mitral Valve Interventions (TRAMI) registry were analyzed in light of previous AVR by means of either standard AVR (SAVR) or transcatheter AVR (TAVR). Out of 791 MC, 68 (8.6%) had been submitted to AVR (68.4% SAVR and 31.6% TAVR). AVR group was significantly older (77.2±8.0 years vs. 75.1±8.6 years; p<0...

The optimal antithrombotic therapies for transcatheter aortic valve implantation (TAVI) and MitraClip implantation have not been well established. We conducted a narrative review from currently available studies between January 2002 and May 2016 to highlight the advantages and disadvantages of antithrombotic therapy use in cardiac catheter-based therapeutic techniques. Recently, these techniques have dramatically altered the approach towards valvular heart diseases management. The introduction into clinical practice, of TAVI for severe aortic stenosis and MitraClip for mitral regurgitation, has revolutionized interventional cardiology...
