BACKGROUND: In preparation for an invasive procedure with a high bleeding risk, patients with a mechanical heart valve temporarily have to discontinue their anticoagulant therapy and are usually bridged with either intravenous unfractionated heparin (UFH) or subcutaneous low-molecular-weight heparin (LMWH). In this study we retrospectively analyzed the safety of UFH versus LMWH as bridging strategy in left-sided mechanical heart valve patients. METHODS: We performed a retrospective multicenter study in four surgical centers in The Netherlands...

We present results of the histopathological workup of a prosthetic aortic valve which was explanted from a 31-year-old woman due to valve thrombosis during early pregnancy. Our images demonstrate nicely thrombotic material directly adherent to the pyrolytic carbon surface in a human specimen.

BACKGROUND: Postmortem imaging (PMI) refers to the imaging of cadavers by computed tomography (CT) and/or magnetic resonance imaging (MRI). Three cases of cerebral infarctions that were not found during life but were newly recognized on PMI and were associated with severe systemic infections are presented. CASE PRESENTATIONS: An 81-year-old woman with a pacemaker and slightly impaired liver function presented with fever. Imaging suggested interstitial pneumonia and an iliopsoas abscess, and blood tests showed liver dysfunction and disseminated intravascular coagulation (DIC)...

AIMS: To date every post-procedural cerebrovascular embolic event (CVE) is dreaded for its potential to accelerate cognitive decline after transcatheter aortic valve implantation (TAVI). This study differentiates the impact of acute (procedural) and post-acute cerebrovascular embolic events (CVEs) on cognitive performance. METHODS: Magnetic resonance imaging (MRI) before, early and late after TAVI was performed to quantify embolic burden. Quantification of diffusion- and T1-weighted lesions, as well as white-matter and total brain volumes, as well as cognitive function testing (MMSE) were assessed in 28 patients with a medium follow-up period of 34 months...

Antiphospholipid syndrome (APS) is an autoimmune hypercoagulable disorder characterized by thrombophilia, vascular thrombosis, and recurrent abortions associated with persistent antiphospholipid antibodies. APS may exist in its primary form, or more commonly is found to be associated with variety of rheumatic disorders, such as systemic lupus erythematosus. Cardiac involvement is not an uncommon complication in primary antiphospholipid patients. Libman-Sacks lesions are typically small, sessile, and wart-like, varying in size from 1-4 mm...

The use of transcatheter aortic valve replacement (TAVR) for high-risk patients with aortic stenosis has rapidly increased during the past years. Accordingly, more and more patients are referred for a follow-up echocardiographic study after TAVR. However, the echocardiographic evaluation of patients who underwent TAVR places specific demands on echocardiographers. Furthermore, TAVR may be associated with new types of complications, which are frequently unrecognized or underestimated due to lack of familiarity with the normal and pathological appearance of TAVR...

INTRODUCTION: Prosthetic Valve Thrombosis (PVT) remains a significant cause of morbidity and mortality after valve replacement. Although surgical treatment is usually preferred as life-saving in cases of obstructive PVT, optimal treatment is yet to be decided. AIM: To evaluate risk factors and outcome of the patients undergoing redo mitral valve surgery for acute PVT. MATERIALS AND METHODS: Between January 2012 and February 2015, 65 patients underwent redo surgery for obstructive PVT of mitral valve in Department of Cardiothoracic Surgery, UN Mehta Institute of Cardiology & Research Centre...

BACKGROUND: Symptomatic mitral regurgitation (MR) is associated with high morbidity and mortality that can be ameliorated by surgical valve repair or replacement. Despite this, many patients with MR do not undergo surgery. Transcatheter mitral valve replacement (TMVR) may be an option for selected patients with severe MR. OBJECTIVES: This study aimed to examine the effectiveness and safety of TMVR in a cohort of patients with native valve MR who were at high risk for cardiac surgery...

PURPOSE OF REVIEW: A recently published study has alerted the cardiovascular community to the existence of a significant and previously unrecognized risk of subclinical valve thrombosis following implantation of surgical and catheter-based bioprosthetic valves. The purpose of this article is to review our current understanding of this new clinical entity and to identify unanswered questions and areas for future research. RECENT FINDINGS: Subclinical bioprosthetic valve thrombosis (BPVT) is a more common phenomenon than previously appreciated...

OBJECTIVES: This study sought to clarify the incidence and predictors of hypoattenuated leaflet thickening (HALT) and mid-term outcomes after transcatheter aortic valve replacement. BACKGROUND: HALT detected on multidetector computed tomography (MDCT) scanning raised concerns about possible subclinical leaflet thrombosis. METHODS: We studied 70 of 100 consecutive patients from a single-center registry who underwent implantation with the Edwards SAPIEN-XT device...

Letter to the Editor Patients with a mechanical heart prosthesis require lifelong anticoagulation to prevent valve thrombosis that could lead to deleterious complications or even death. LMWH protocols have proven feasible and safe in most mechanical prosthesis bearers requiring an interruption of oral anticoagulation because of surgery. However, some patient populations have not been included in trials and might behave differently. To this end, we would like to present the case of a 56-year-old man with mechanical aortic prosthesis treated with bevacizumab...

Treatment of end-stage heart failure includes cardiac transplantation or ventricular assist device (VAD) therapy. While increasingly prevalent, current VAD therapy has inherent complications, including thrombosis. Studies have demonstrated that VAD implantation alters intra-cardiac blood flow, creating areas of stagnation that predispose to thrombus formation. Two potential surgical configurations exist for VAD implantation: through the apical or diaphragmatic surfaces of the heart. We hypothesized that diaphragmatic implantation causes more stagnation than apical implantation...

Prosthetic valve thrombosis is one of the major causes of primary valve failure, which can be life-threatening. Multimodality imaging is necessary for determination of leaflet immobilization, cause of underlying pathology (thrombus versus pannus or both), and whether thrombolytic therapy attempt in the patient would be successful or surgery is needed. Current guidelines for the management of prosthetic valve thrombosis lack definitive class I recommendations due to lack of randomized controlled trials, and usually leave the choice of treatment to the clinician's experience...

Thrombosis of transcatheter aortic valve implantation (TAVI) is an uncommon complication that commonly occurs weeks to months following the procedure. Herein are described the details of a patient who presented with a recurrence of symptoms days after intervention with a bioprosthesis thrombosis that was successfully treated with direct oral anticoagulant (DOAC) therapy and resulted in hemodynamic improvement and resolution of symptoms. Whilst a previous trial of DOAC therapy with mechanical valves was stopped due to elevated events in comparison to warfarin, a TAVI valve may be different, and the rapid onset of action and reduced bleeding risk may be beneficial in this patient group...

BACKGROUND: Rheumatic mitral valve stenosis (RMVS)-induced left atrial thrombus (LAT) and embolic complications may have clinically devastating consequences. Stasis in the left atrium induced by valvular obstruction is a major factor in the development of thrombus. However, the development of thrombus may not be solely associated with stasis, as it is known that the inflammatory process increases the tendency for thrombosis. The study aim was to examine the relationship between the neutrophil-to-lymphocyte ratio (NLR), an indicator of inflammation, and the existence of LAT...

BACKGROUND: The anticoagulation of biological heart valves remains a 'hot spot' of discussion in various domains due to the risk of developing valve thrombosis and arterial thromboembolism. The situation has always been controversial, especially during the early postoperative phase. The American College of Cardiology/ American Heart Association and European Society of Cardiology guidelines recommend the use of warfarin for the first three months after biological aortic valve replacement (BAVR), although the American College of Chest Physicians guidelines suggest that these recommendations are experience-based and that the risk/benefit is unclear...
