Abstract
Mitral valve stenosis remains highly prevalent among the US population although with dramatically shifting demographics. The significance of rheumatic mitral disease in developing nations persists, despite improvements in preventative measures and early detection, and its presence in developed countries is still evident as observed through international migration. In addition, the substantial growth in the aging population with a heightened occurrence of concurrent cardiovascular risk factors is leading to an increased prevalence of chronic calcific degeneration and degeneration of previously repaired or replaced valves. This article aims to review various transcatheter therapies in the treatment of mitral valve stenosis.

Abstract
Up to 20 % of patients presenting with acute heart failure and cardiogenic shock have a structural etiology. Despite efforts in timely management, mortality rates remain alarmingly high, ranging from 50 % to 80 %. Surgical intervention is often the definitive treatment for structural heart disease; however, many patients are considered high risk or unsuitable candidates for such procedures. Consequently, there has been a paradigm shift towards the development of novel percutaneous management strategies and temporizing interventions. This article aims to provide a comprehensive review of the pathophysiology of valvular and structural heart conditions presenting in cardiogenic shock, focusing on the evolving landscape of mechanical circulatory support devices and other management modalities.

Abstract
INTRODUCTION AND AIM The advances and the wide use of brain imaging have considerably increased the prevalence of silent brain infarctions (SBI). We aim in this study to determine the prevalence of SBI in patients presenting with acute cardioembolic stroke and the predictive cardiovascular risk factors. METHODS This retrospective study included 267 patients presenting with acute cardioembolic stroke in the emergency and/or neurology departments of the Hassan II University Hospital Center. Clinical, biological and echocardiographic characteristics were recorded. All patients were screened for SBI by brain imaging. RESULTS The prevalence of SBI in our series was 46%. A group of 203 non-valvular patients and a group of 64 valvular patients were distinguished. In non-valvular group, the average age was 72.97±10.53years. The prevalence of SBI was 45.3%. Forty-four percent of patients with SBI had atrial fibrillation (AF). In multivariate regression analysis, the history of previous stroke, CHA2DS2-VASc Score≥4, enlarged left atrium (LA), the association of AF with enlarged LA and the lability of International Normalized Ratio in patients initially treated with anticoagulants were significantly associated with the occurrence of SBI (P=0.013, P=0.032, P=0.0001, P=0.01, P=0.03, respectively). Territorial location was significantly the most frequent (P=0.007). In valvular group, the average age was 57.19±14.38years. The prevalence of SBI was 48.4%. In multivariate regression analysis, SBI were significantly associated with moderate or severe mitral stenosis (P=0.02) and with the enlarged LA (P=0.02). In all patients, Modified Rankin Scale at 3 months of discharge from the acute stroke was significantly higher (mRS≥3) in patients with SBI (P=0.04). CONCLUSIONS SBI requires good management of associated cardiovascular risk factors in a population presenting with initial cardioembolic stroke.

Abstract
BACKGROUND Rheumatic heart disease remains the most common cardiovascular disease in children and young adults. The outcome of interventional versus medical therapy on the long term is not fully elucidated yet. This study provides contemporary data on the clinical profile, treatment and follow up of patients with rheumatic mitral stenosis (MS) in Tanzania. METHODS Patients' medical information, investigations and treatment data were recorded in this prospective cohort study. They were followed up for 6-24 months to determine the long-term outcome. Interventional therapy was defined as a combination of surgery and percutaneous balloon mitral valvuloplasty. Kaplan-Meier curves and Cox proportional hazards model were used in analyses. p-Value < 0.05 was considered statistically significant. RESULTS We enrolled 290 consecutive patients. Interventions were done in half of the patients. Median follow up was 23.5 months. Mortality was higher in the medical than interventional treatment (10.4% vs. 4%, log-rank p = 0.001). Median age was 36 years, females (68.3%) and low income (55.5%). Multivalvular disease was found in 116 (40%) patients, atrial fibrillation (31.4%), stroke/transient ischaemic attack (18.9%) and heart failure class III-IV (44.1%). Median (IQR) duration of disease was 3 (4) years, secondary prophylaxis (27.7%) and oral anticoagulants use (62.3%). In multivariable analysis, the risk of death among patients on medical was 3.07 times higher than those on interventional treatment (crude HR 3.07, 95% CI 1.43-6.56, p = 0.004), 2.44 times higher among patients with arrhythmias versus without arrhythmias (crude HR 2.44, 95% CI 1.19-4.49, p = 0.015) and 2.13 times higher among patients with multivalvular than single valve disease (crude HR 2.13, 95% CI 1.09-4.16, p = 0.026). CONCLUSIONS Intervention is carrying low mortality compared to medical treatment. Arrhythmias and multivalvular disease are associated with a high mortality. Rheumatic MS is more prevalent in young people, females and individuals with low income. There is a late hospital presentation and a low use of both secondary prophylactic antibiotics and anticoagulants.

Abstract
Cardioembolic strokes account for 20-25% of all ischaemic strokes, with their incidence increasing with age. Cardiac imaging plays a crucial role in identifying cardioembolic causes of stroke, with early and accurate identification affecting treatment, preventing recurrence, and reducing stroke incidence. Echocardiography serves as the mainstay of cardiac evaluation. Transthoracic echocardiography (TTE) is the first line in the basic evaluation of structural heart disorders, valvular disease, vegetations, and intraventricular thrombus. It can be used to measure chamber size and systolic/diastolic function. Trans-oesophageal echocardiography (TOE) yields better results in identifying potential cardioembolic sources of stroke and should be strongly considered, especially if TTE does not yield adequate results. Cardiac computed tomography and cardiac magnetic resonance imaging provide better soft tissue characterisation, high-grade anatomical information, spatial and temporal visualisation, and image reconstruction in multiple planes, especially with contrast. These techniques are useful in cases of inconclusive echocardiograms and can be used to detect and characterise valvular lesions, thrombi, fibrosis, cardiomyopathies, and aortic plaques. Nuclear imaging is not routinely used, but it can be used to assess left-ventricular perfusion, function, and dimensions and may be useful in cases of infective endocarditis. Its use should be considered on a case-by-case basis. The accuracy of each imaging modality depends on the likely source of cardioembolism, and the choice of imaging approach should be tailored to individual patients.

Abstract
Valvular heart disease (VHD) has been a significant health problem, particularly in developed countries, in relation to the aging population. Recent developments in the management of VHD require a more accurate assessment of disease severity to determine the need for transcatheter interventions or open heart surgery. Stress echocardiography is a crucial imaging modality for identifying the underlying pathology of VHD. Optimal administration of exercise or intravenous drugs may reveal hemodynamic abnormalities under stress without posing an invasive risk. Therefore, the implementation of stress echocardiography is recommended for determining interventional indications and risk stratification in mitral regurgitation and aortic stenosis. In addition, recent evidence has accumulated regarding the usefulness of stress echocardiography in various conditions including mitral stenosis, aortic regurgitation, and post-interventional VHD. Here, we summarize the current evidence and future perspectives on stress echocardiography in VHD.

Abstract
Mitral facies is a classical feature of chronic mitral stenosis (MS) that commonly associated with low cardiac output and pulmonary hypertension. A 44-year-old woman presented with 10-year history of refractory right heart failure. We noted distinctive malar rash appearance on her face known as "mitral facies." An echocardiogram revealed severe MS and other significant valve involvement with typical characteristics of rheumatic valvular heart disease. Doppler measurement showed decreased cardiac output and severe pulmonary hypertension in this patient. The mitral facies could be an alarming sign of a more severe and advanced form of MS. It also can be a marker of impaired cardiac output and concomitant severe pulmonary hypertension.

Abstract
Socioeconomic factors such as poor health and poor nutrition in low- and middle-income countries (LMICs) may favour inflammatory reactions, thus contributing to the recurrence of rheumatic fever (RF) and thereby modifying trends in rheumatic heart disease (RHD). Apart from epidemiological studies, studies of HIV infections in RHD patients are limited. This systematic review synthesises data on the prevalence and impact of HIV infections or AIDS on RHD from PubMed, Scopus, Web of Science databases up to April 2021. The outcomes were managed using PRISMA guidelines. Of a total of 15 studies found, 10 were eligible for meta-analyses. Meta-analysis found that 17% (95 % CI 8-33, I2 = 91%) of adults in cardiovascular disease (CVD) cohorts in Southern Africa are HIV positive. The proportion of RHD diagnosed among people living with HIV was 4% (95% CI 2-8, I2 = 79%) for adults but lower [2% (95% CI 1-4, I2 = 87%)] among perinatally infected children. Despite limited reporting, HIV-infected patients with RHD are prone to other infections that may enhance cardiac complications due to poor immunological control. PROSPERO registration number: CRD42021237046.

Abstract
Mitral stenosis (MS) is not a common entity in modern-day medicine, especially in developed countries, as the most common etiology is still rheumatic fever. MS can present mainly with a wide range of cardiac symptoms. However, infrequently, MS can cause extra-cardiac symptoms as well. We present a case report of a patient with severe bioprosthetic mitral valve stenosis with intermittent hemoptysis and cardiogenic shock. We aim to report this case to remind clinicians about this uncommon but significant cause of hemoptysis. This case report also emphasizes the importance of utilizing a team approach while treating patients with severe MS, especially if they have serious complications that could be life-threatening. We also aim to add to the current literature by reporting this case.

Abstract
Rheumatic heart disease (RHD) remains a significant cardiovascular burden in the world even though it is no longer common in affluent countries. Centuries of history surrounding this disease provide us with a thorough understanding of its pathophysiology. Infections in the throat, skin, or mucosa are the gateway for Group A Streptococcus (GAS) to penetrate our immune system. A significant inflammatory response to the heart is caused by an immunologic cascade triggered by GAS antigen cross-reactivity. This exaggerated immune response is primarily responsible for cardiac dysfunction. Recurrent inflammatory processes damage all layers of the heart, including the endocardium, myocardium, and pericardium. A vicious immunological cycle involving inflammatory mediators, angiotensin II, and TGF-β promotes extracellular matrix remodeling, resulting in myocardial fibrosis. Myocardial fibrosis appears to be a prevalent occurrence in patients with RHD. The presence of myocardial fibrosis, which causes left ventricular dysfunction in RHD, might be utilized to determine options for treatment and might also be used to predict the outcome of interventions in patients with RHD. This emerging concept of myocardial fibrosis needs to be explored comprehensively in order to be optimally utilized in the treatment of RHD.

Abstract
BACKGROUND The assessment of outcomes of interventions based on the patient's perspective using patient-reported outcome measures (PROMs) has been increasingly highlighted in clinical practice. However, health related quality of life (HRQoL), one of the common constructs measured by PROMs remain unknown among patients after heart valve replacement (HVR) in Tanzania. OBJECTIVES To assess the HRQoL amongst patients operated on for rheumatic mitral stenosis at Jakaya Kikwete Cardiac Institute (JKCI). METHODS A prospective study of patients operated on due to rheumatic mitral stenosis at JKCI from January 2020 to April 2021 was undertaken. The HRQoL was assessed by using the MacNew questionnaire, addressing three domains (physical, emotional, and social function); the score ranges from 0 to 7. We categorized HRQoL as low (mean score ≤ 4.9), moderate (5-6) and high (> 6). We analysed several sociodemographic and clinical variables for HRQoL. RESULTS Out of 54 patients, there were 34 females and 20 males. Their mean (± SD) age was 37.98 (± 12.58) years. The reliability of translated Kiswahili version of MacNew was good. The mean (± SD) global scores were 3.47 ± 0.59, 4.88 ± 0.71 and 6.14 ± 0.50 preoperatively, at 3 months and 6 months respectively (p-values < 0.001 preoperatively vs. 3 months, preoperatively vs. 6 months and at 3 months vs. 6 months). The median of individual mean difference HRQoL score pre-operatively and at 6 months was 2.67. The preoperative and 6 months mean difference HRQoL scores were higher among patients with vs. without atrial fibrillation (2.95 ± 0.59 vs. 2.45 ± 0.53, p = 0.003) and those on anticoagulants (preoperatively) vs. not on anticoagulants (3.14 ± 0.58 vs. 2.57 ± 0.57, 0.009). The mean difference HRQoL scores were similar for sociodemographic and other clinical parameters, including those with stroke vs. without stroke. CONCLUSION Six months after HVR the overall MacNew HRQoL scores improved markedly. This improvement in HRQoL was regardless of the presence of comorbidities (e.g. stroke and atrial fibrillation) which underscores the importance of considering valvular surgery if they fit the criteria. Clinicians and researchers in low-resource settings should collaborate to promote the utilization of PROMs in the routine care of patients.

Abstract
BACKGROUND Cardiac remodeling in rheumatic mitral stenosis (MS) is complex and incompletely understood. The objective of this study was to evaluate cardiac structural and functional changes in a cohort of patients with rheumatic MS using cardiovascular magnetic resonance (CMR). METHODS This retrospective study included 40 patients with rheumatic MS, consisting of 19 patients from India, 15 patients from China, and 6 patients from Mexico (median (interquartile range (IQR)) age: 45 years (34-55); 75% women). Twenty patients were included in the control group. CMR variables pertaining to morphology and function were collected. Late gadolinium enhancement (LGE) sequences were acquired for tissue characterization. Statistical analyses were performed using the Kruskal-Wallis test and the chi-square test. RESULTS Compared to the control group, patients with MS had lower left ventricular (LV) ejection fraction (51% (42%-55%) vs 60% (57%-65%), p < 0.001), lower right ventricular (RV) ejection fraction (44% (40%-52%) vs 64% (59%-67%), p < 0.001), higher RV end-diastolic volume (72 (58-87) mL/m2 vs 59 (49-69) mL/m2, p = 0.003), larger left atrial volume (87 (67-108) mL/m2 vs 29 (22-34) mL/m2, p < 0.001), and right atrial areas (20 (16-23) cm2 vs 13 (12-16) cm2, p < 0.001). LGE was prevalent in patients with rheumatic MS (82%), and was commonly located at the RV insertion sites. Furthermore, the patient cohorts from India, China, and Mexico were heterogeneous in terms of baseline characteristics and cardiac remodeling. CONCLUSION Our findings demonstrated that biventricular dysfunction, right and left atrial remodeling, and LGE at the RV insertion sites are underappreciated in contemporary rheumatic MS. Further studies are needed to elucidate the prognostic implications of these findings.

Abstract
Mitral valve diseases are relatively rare in the paediatric population; however, they can cause considerable mortality and morbidity worldwide. Acquired causes are a major contributor to cardiovascular disease burden in the paediatric population. Diseases can be detected before birth, at birth, or when the child is older and presents with symptoms of advanced heart failure. Definitive management consists of surgical intervention, with mitral valve replacement being the gold standard.Conclusion: Repair has been gaining popularity; however, its outcomes require further study. Percutaneous mitral balloon valvuloplasty is an emerging technique which holds promise as a bridge to surgical treatment. The effect of these interventions on quality of life must be emphasised and requires further study. What is Known: • The epidemiology of mitral valve disease in the paediatric population - predominant causes include rheumatic disease and congenital defects. • Mitral valve repair and replacement are the standard treatment methods for paediatric mitral valve disease. What is New: • Emergence of percutaneous mitral valve interventions and their potential as bridge-to-surgery or definitive treatment in high-risk surgical candidates. • Recent evidence comparing mitral valve repair and replacement in the paediatric population demonstrates increasing popularity of repair techniques.

Abstract
Das zweite Manual zur Indikation und Durchführung der Echokardiographie bezieht sich auf spezifische Anwendungen der Echokardiographie und besondere Fragestellungen bei speziellen Patientengruppen. Dabei stehen v. a. praktische Aspekte im Vordergrund. Methodisch etabliert sind die transösophageale Echokardiographie, die Stressechokardiographie und die Kontrastechokardiographie. Bei nahezu allen echokardiographischen Untersuchungen spielen aktuell 3‑D-Echokardiographie und Deformationsbildgebung eine Rolle. Das gesamte Spektrum der echokardiographischen Möglichkeiten wird derzeit in Notfall- und Intensivmedizin, bei der Überwachung und Führung von Katheterinterventionen, bei strukturellen Herzerkrankungen, bei herzchirurgischen Operationen, bei der Nachsorge von kardialen Unterstützungssystemen, bei kongenitalen Vitien im Erwachsenenalter und bei der Versorgung von hochinfektiösen Patienten in Pandemiezeiten angewandt. Die diagnostischen Fortschritte der konventionellen und modernen echokardiographischen Anwendungen stehen im Fokus dieses Manuals. Die 3‑D-Echokardiographie zur Charakterisierung der kardialen Morphologie und die Deformationsbildgebung zur Objektivierung der kardialen Funktion sind bei vielen Indikationen im klinischen Alltag etabliert. Die Stressechokardiographie zur Ischämie‑, Vitalitäts- und Vitiendiagnostik, die Bestimmung der koronaren Flussreserve und die Kontrastechokardiographie bei der linksventrikulären Wandbewegungsanalyse und kardialen Tumordetektion finden zunehmend klinische Anwendung. Wie für die konventionelle Echokardiographie im ersten Manual der Echokardiographie 2009 beschrieben, erfordert der Einsatz moderner echokardiographischer Verfahren die standardisierte Dokumentation und Akquisition bestimmter Bildsequenzen bei optimierter Geräteeinstellung, da korrekte und reproduzierbare Auswertungen nur bei guter Bildqualität möglich sind.

Abstract
OBJECTIVE The decision to perform percutaneous mitral commissurotomy (PMC) on asymptomatic patients requires careful weighing of the potential benefits against the risks of PMC, and we conducted a multicentre, randomised trial to compare long-term outcomes of early PMC and conventional treatment in asymptomatic, severe mitral stenosis (MS). METHODS We randomly assigned asymptomatic patients with severe MS (defined as mitral valve area between 1.0 and 1.5 cm2) to early PMC (84 patients) or to conventional treatment (83 patients). The primary endpoint was a composite of major cardiovascular events, including PMC-related complications, cardiovascular mortality, cerebral infarction and systemic thromboembolic events. The secondary endpoints were death from any cause and mitral valve (MV) replacement during follow-up. RESULTS In the early PMC group, there were no PMC-related complications. During the median follow-up of 6.4 years, the composite primary endpoint occurred in seven patients in the early PMC group (8.3%) and in nine patients in the conventional treatment group (10.8%) (HR 0.77; 95% CI 0.29 to 2.07; p=0.61). Death from any cause occurred in four patients in the early PMC group (4.8%) and three patients in the conventional treatment group (3.6%) (HR 1.30; 95% CI 0.29 to 5.77). Ten patients (11.9%) in the early PMC group and 17 patients (20.5%) in the conventional treatment group underwent MV replacement (HR 0.59; 95% CI 0.27 to 1.29). CONCLUSIONS Compared with conventional treatment, early PMC did not significantly reduce the incidence of cardiovascular events among asymptomatic patients with severe MS during the median follow-up of 6 years. TRIAL REGISTRATION NUMBER NCT01406353.

Abstract
BACKGROUND Use of direct oral anticoagulants (DOACs) for the treatment of left ventricular (LV) thrombus has gained considerable interest. OBJECTIVE We aimed to evaluate if DOACs are effective in the treatment of LV thrombus compared with warfarin. METHODS We evaluated the medical records of patients diagnosed with a new LV thrombus at a tertiary medical center. The primary outcome was the composite of thrombus persistence, stroke, or systemic embolism. We adjusted for potential confounders using multiple logistic regression. The safety outcome was the composite of hemorrhagic stroke or bleeding requiring blood transfusion. RESULTS A total of 129 patients were treated with warfarin and 22, with a DOAC. In unadjusted analysis, 54.3% of patients treated with warfarin met criteria for the efficacy outcome as compared with 40.9% of patients treated with a DOAC (P = 0.25). In adjusted analysis, no difference between groups was observed (odds ratio = 0.39; 95% CI = 0.14-1.06; P = 0.07 for DOAC vs warfarin). In all, 3.9% of patients treated with warfarin met safety criteria as compared with 4.5% of patients treated with a DOAC. A total of 8 patients in the warfarin group had a stroke or systemic embolism as compared with 0 patients in the DOAC group (P = 0.37). CONCLUSION AND RELEVANCE Our data suggest that DOACs may be reasonable alternatives for treatment of LV thrombus. When added to the totality of available studies, this study demonstrates that the effectiveness of DOACs in LV thrombus remains uncertain. Randomized clinical trials are needed.

Abstract
BACKGROUND The function of both ventricles has been suggested to be affected in patients with mitral stenosis. In this study, it was aimed to investigate deformation properties of right (RV) and left ventricle (LV) in rheumatic mitral stenosis (MS) patients with three-dimensional speckle tracking echocardiography (3D-STE). METHODS A total of 60 patients were included in the study (20 patients with mild MS diagnosis, 20 patients with moderate MS diagnosis, and 20 healthy volunteers). Three-dimensional echocardiography datasets were obtained for both ventricles in all patients. LV global longitudinal strain (GLS), LV torsion, RV free wall (FW) LS, and interventricular septal (IVS) LS measurements were analyzed. RESULTS The LV ejection fraction (EF), RV fractional area change, peak systolic velocity of the tricuspit annulus, isovolumic acceleration, and tricuspid annular plane systolic excursion values were statistically similar and in the normal range. The LV GLS measurements were significantly different among the groups by being highest in the control group and least in the moderate stenosis group. Patients with MS showed higher torsional values, correlated with MS severity. IVS LS, RVFW LS values obtained by RV analysis also differed significantly among groups. The RVFW-GLS values only showed significant difference between the control group and moderate MS group. CONCLUSION Patients with MS showed lower LV-GLS and higher LV torsion values. RV deformation indices showed significant decrease in correlation with the severity of the mitral stenosis. In conclusion, our data suggest that subclinical LV and RV systolic dysfunction is present in mild-moderate MS patients and this dysfunction can be detected by 3D-STE.

Abstract
Double-inlet left ventricle (DILV) is the commonest form of the anatomic univentricular heart which has different ventriculoarterial connection; generally, the most prevalent type is DILV with the hypoplastic right ventricle on the left side. The disease is associated with several heart defects, and the treatment method is different based on the anatomy of the heart, but treatment methods are almost always palliative. In this paper, we described one adult patient with DILV and severe left AV (atrioventricular valve) stenosis who is managed with a novel palliative intervention; it means AFR (atrial flow regulator) device implantation for the first time.

Abstract
Objectives To determine the changes produced in mitral valve morphology after Percutaneous Trans-Venous Mitral Commissurotomy. Methods Patients with mitral stenosis who underwent PTMC at the cardiology department of Lady Reading Hospital, Peshawar, Pakistan, from 2006-2016 were included in this study. All the data were manually obtained from the electronic medical record (M.F.E.). Wilkin's echocardiographic scoring system was used to assess the severity of mitral valve thickness, leaflet mobility, valvular calcification, and Subvalvular disease. The student t-test was used for mean comparison. P-value < 0.05 was considered significant. Results Of the total 229 patients, males were 96(41.9%), and females were 133(58.1%). The mean [SD] age of the patients was 25 ± 11years. The total Wilkin score was 7 ±1.5. 151(65.9%) were in New York Heart Association (NYHA) functional class III, and 78(34.1%) were in NYHA class IV. There was no immediate change after PTMC in systolic myocardial velocities (SV) measured at the lateral tricuspid annulus. The 2D mitral valve area increased from 0.98±0.94 cm2 to 1.78 ± 0.44 cm2 (P=0.001). Left Atrium diameter was 5.16±0.75 mm prior to PTMC, significantly decreased to 4.7± 0.7 mm (p=0.005) after PTMC. Ejection fraction (Left Ventricular Ejection Fraction) changed from 60.45± 8.25 mm Hg to 62.76±10 mm Hg (p=0.001). Mean Right Ventricular Ejection Fraction (RVEF) of patients before PTMC was 48.7 ± 4.7%, did not change significantly immediately after PTMC. Conclusion PTMC is associated with significant changes in mitral valve morphology in terms of splitting of the fused mitral commissures, increased MVA, improved leaflet excursion, and splitting of the subvalvular structures.

Abstract
Management of mitral valve disease in the western world continues to lag behind its aortic counterpart, particularly in the realm of percutaneous valve replacement. It is a more complex anatomical region, with varying disease states and unique pathophysiological and epidemiological characteristics that make it a distinct challenge to treat in modern medicine. Latest research and development, however, have provided new answers to the challenges associated with the mitral valve. In this review, the most common disease states afflicting the mitral valve are outlined, specific challenges associated with treatment are discussed, and both current and cutting-edge replacement devices are described. This review focuses on replacement and prosthetic devices, while acknowledging the role of valve repair. The future of mitral valve replacement remains to be seen, as new methodologies and prosthetic designs continue to present themselves as the best answer to the challenge.

Valvular and Nonvalvular Atrial Fibrillation in Patients Undergoing Transcatheter Aortic Valve Replacement. JACC Cardiovasc Interv 2020; 13:2124-2133. [PMID: 32972574 DOI: 10.1016/j.jcin.2020.05.049] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 05/20/2020] [Accepted: 05/22/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVES The aim of this study was to investigate the impact of valvular and nonvalvular atrial fibrillation (AF) in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND AF has been associated with adverse clinical outcomes after TAVR. However, the differential impact of valvular as opposed to nonvalvular AF has not been investigated. METHODS In a retrospective analysis of a prospective registry, valvular AF was defined as AF in the setting of concomitant mitral stenosis or the presence of a mitral valve prosthesis. The presence of mitral stenosis was determined by pre-procedural echocardiography. The primary endpoint was a composite of cardiovascular death or disabling stroke at 1 year after TAVR. RESULTS Among 1,472 patients undergoing TAVR between August 2007 and June 2018, AF was recorded in 465 patients (31.6%) and categorized as nonvalvular in 376 (25.5%) and valvular in 89 (6.0%). AF scores including HAS-BLED, CHADS2, and CHA2DS2-VASc were comparable between patients with nonvalvular and valvular AF. The primary endpoint occurred in 9.3% of patients with no AF, in 14.5% of patients with nonvalvular AF (hazard ratio: 1.57; 95% confidence interval: 1.12 to 2.20; p = 0.009), and in 24.2% of patients with valvular AF (hazard ratio: 2.75; 95% confidence interval: 1.71 to 4.41; p < 0.001). Valvular AF conferred an increased risk for cardiovascular death or disabling stroke compared with nonvalvular AF (hazard ratio: 1.77; 95% confidence interval: 1.07 to 2.94; p = 0.027). CONCLUSIONS The presence of valvular AF in patients undergoing TAVR increased the risk for cardiovascular death or disabling stroke compared with both no AF and nonvalvular AF.

Abstract
In this work, a novel algorithmic scheme is developed that processes echocardiogram videos, and tracks the movement of the mitral valve leaflets, and thereby estimates whether the movement is symptomatic of a healthy or diseased heart. This algorithm uses automatic Otsu's thresholding to find a closed boundary around the left atrium, with the basic presumption that it is situated in the bottom right corner of the apical 4 chamber view. A centroid is calculated, and protruding prongs are taken within a 40-degree cone above the centroid, where the mitral valve is located. Binary images are obtained from the videos where the mitral valve leaflets have different pixel values than the cavity of the left atrium. Thus, the points where the prongs touch the valve will show where the mitral valve leaflets are located. The standard deviation of these points is used to calculate closeness of the leaflets. The estimation of the valve movement across subsequent frames is used to determine if the movement is regular, or affected by heart disease. Tests conducted with numerous videos containing both healthy and diseased hearts attest to our method's efficacy, with a key novelty in being fully unsupervised and computationally efficient.

Abstract
Rheumatic heart disease (RHD) is a major cause of cardiovascular morbidity and mortality in low- and middle-income countries, where living conditions promote spread of group A β-haemolytic streptococcus. Autoimmune reactions due to molecular mimicry of bacterial epitopes by host proteins cause acute rheumatic fever (ARF) and subsequent disease progression to RHD. Despite knowledge of the factors that predispose to ARF and RHD, determinants of the progression to valvular damage and the molecular events involved remain incompletely characterised. This review focuses on altered protein expression in heart valves, myocardial tissue and plasma of patients with RHD and pathogenic consequences on RHD. Proteins mainly involved in structural organization of the valve matrix, blood homeostasis and immune response were altered due to RHD pathogenesis. Study of secreted forms of these proteins may aid the development of non-invasive biomarkers for early diagnosis and monitoring outcomes in RHD. Valve replacement surgery, the single evidence-based strategy to improve outcomes in severe RHD, is costly, largely unavailable in low- and middle-income countries (LMIC) and requires specialised facilities. When diagnosed early, penicillin prophylaxis may be used to delay progression to severe valvular damage. Echocardiography and cardiovascular magnetic resonance and the standard imaging tools recommended to confirm early diagnosis remain largely unavailable and inaccessible in most LMIC and both require expensive equipment and highly skilled persons for manipulation as well as interpretation of results. Changes in protein expression in heart valves and myocardium are associated with progressive valvular deformation in RHD. Understanding these protein changes should shed more light on the mechanisms of pathogenicity, while secreted forms of these proteins may provide leads towards a biomarker for non-invasive early detection of RHD.

Abstract
BACKGROUND We herein aimed for analysis of influence of mitral annular calcification (MAC) and mitral stenosis (MS) on outcomes in transcatheter aortic valve implantation (TAVI). METHODS Between 11/2009 and 06/2017, 1,058 patients underwent TAVI in the presence of concomitant MAC or MS at our center. Subgroups were built and multivariate logistic regression, COX regression, Kaplan-Meier survival analyses, and receiver operating characteristics method were performed. RESULTS Thirty-day mortality was 7.5% (79/1,058) with highest mortality in patients severe MS (MAC: 3.4% vs. mild MS: 5.9% vs. moderate MS: 15.0% vs. severe MS: 72.7%; p < 0.001). Moderate-to-severe MS (odds ratio [OR]: 7.75, confidence interval [CI]: 3.94-16.26, p < 0.001), impaired left ventricular ejection fraction (OR: 1.38, CI: 1.10-1.72, p < 0.01), and coronary artery disease (OR: 1.36, CI: 1.11-1.67, p < 0.01) were predictive of 30-day survival. Left ventricular systolic/end-diastolic pressure drop of <59.5 mm Hg / <19.5 mm Hg was associated with increased mortality. CONCLUSIONS TAVI in the presence of MAC and mild MS is associated with acceptable acute outcomes but should be considered high-risk procedures in patients with moderate and especially those with severe MS. Our results suggest adverse hemodynamics after TAVI with concomitant MS, which may be caused by underfilling of the left ventricle leading to low-cardiac output.

Abstract
AIM Patients with severe mitral stenosis (MS) and their clinicians typically choose percutaneous transvenous mitral commissurotomy (PTMC) over surgical commissurotomy (SC). However, the durability of PTMC relative to SC is uncertain. We compared the efficacy, safety and durability of PTMC with SC for the treatment of MS. METHODS We searched EMBASE, MEDLINE and WHO ICTRP registers for randomised controlled trials (RCTs) comparing PTMC, and open and/or closed mitral commissurotomy. The principal outcomes were rate of re-intervention and symptomatic improvement as inferred from the surrogate measures of immediate postprocedural mitral valve area (MVA), MVA at ≥6 month follow-up, incidence of mitral regurgitation (MR) and restenosis. We calculated weighted mean differences (WMD) for continuous outcomes, relative risks (RR) for binary outcomes and pooled outcomes using random-effects models and assessed the quality of evidence using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. RESULTS Seven RCTs with 553 patients proved eligible. Pooled estimates showed no convincing difference in the risk of restenosis or re-intervention (15/100 fewer with PTMC, 95% CI (-20 to +8); quality of evidence: moderate) or in symptoms as inferred from immediate MVA (WMD 0.15, 95% CI (-0.18 to 0.48): very low), from the incidence of postprocedural severe MR (3/100 more with PTMC, 95% CI (-1 to +10): moderate) or from MVA at 30 months. CONCLUSION Until data demonstrating convincing superiority of SC over PTMC become available, our results support the current practice of recommending PTMC to young patients with MS and favourable valve morphology, as it is associated with lower peri-procedural morbidity.

Abstract
BACKGROUND The objective of this study was to compare long-term outcomes of Mosaic (Medtronic, Minneapolis, MN) porcine mitral valves to Carpentier-Edwards (Edwards Lifesciences, Irving, CA) bovine pericardial mitral valves. METHODS From 2001 through 2017 at a single institution, 940 patients received a mitral bioprosthesis, of which 463 (49.3%) were porcine and 477 (50.7%) were bovine pericardial. Retrospective review of the procedure and the postoperative clinical course, including echocardiography, through August 2018 were analyzed. All consecutive mitral valve replacements over the study period were included. Follow-up was 99% (929 patients) complete for a total of 6045 patient-years (mean, 6.4 ± 4.5 years). A propensity-matched cohort of 802 mitral bioprosthesis was used for outcome analyses. RESULTS Operative mortality of the 940 patients was 5.4% (n = 51) and incidence of postoperative stroke was 2.1% (n = 20). Overall survival of the propensity-matched patients at 10 and 15 years was 49.7% (95% confidence interval [CI] 45.5%-53.7%) and 23.3% (95% CI 17.9%-29.3%), respectively. Survival at 15 years was 24.0% (95% CI 18.0%-30.5%) for porcine and 16.5% (95% CI 5.5%-32.6%) for bovine implants, which was not significantly different (P = .67). Overall cumulative incidence for reoperative structural valve deterioration at 15 years was 7.9% (95% CI 4.7%-12.3%) for porcine valves versus 13.2% (95% CI 8.1%-19.5%) for pericardial valves (P < .001). For patients age younger than 65 years, structural valve deterioration at 15 years was 15.8% (95% CI 7.4%-27.0%) versus 30.2% (95% CI 15.1%-46.8%) for porcine and pericardial valves, respectively (P = .009). Overall average time to reoperation for structural valve deterioration for porcine valves was 11.1 ± 2.3 years vs 6.8 ± 2.3 years for bovine pericardial valves (P < .001). CONCLUSIONS In long-term follow-up, of patients younger than 65 years of age undergoing mitral valve replacement, bovine pericardial valves experienced earlier and more frequent structural valve deterioration than porcine valves.

Indian Heart J 2019; 70 Suppl 3:S338-S346.

Abstract
AIM The aim of the study was to compare the immediate and late clinical outcomes of balloon mitral valvotomy (BMV), based on the immediate post-BMV valve area and percentage gain in mitral valve area (MVA). METHODS Clinical data of 818 consecutive patients who underwent BMV in our institute from 2000 to 2008 were analyzed retrospectively. They were categorized into three groups based on the postprocedural MVA and percentage gain in valve area-(1) 50% gain with final MVA <1.5 cm2, group 1 (fair result); (2) final MVA of ≥1.5 cm2, group 2 (good result); and (3) <50% gain with final MVA <1.5 cm2, group 3 (suboptimal result). RESULTS The baseline characteristics of the three patient groups were clearly distinct. Those who had <50% gain with final MVA <1.5 cm2 were older and had higher incidence of atrial fibrillation (17 [22.4%]), heart failure (32 [42.1%]), pulmonary artery hypertension (45 [59.2%]), and significantly deformed valves (39 [51.3%]) at baseline. At a mean follow-up period of 5.64 ± 3.84 years, incidence of redo BMV (23 [4.6%]) and mitral valve replacement (17 [3.4%]) was higher in them than those with immediate MVA ≥1.5 cm2. Among those with MVA <1.5 cm2, events on follow-up were similar irrespective of the percentage gain in MVA. CONCLUSIONS Immediate postprocedural MVA of ≥1.5 cm2, and not percentage gain, predicts better long-term clinical outcomes after BMV. Patients who had less than 50% gain with final MVA <1.5 cm2 represent high-risk population with advanced mitral valve disease and comorbidities.

Abstract
BACKGROUND Over the last 25 years, cardiovascular magnetic resonance imaging (CMR) has emerged as an alternative to echocardiography for assessment of valvular heart disease (VHD). Although echo remains the first-line imaging modality for the assessment of patients with VHD, CMR can now provide a comprehensive assessment in many instances. Using a combination of techniques, CMR provides information on valve anatomy and enables quantitative analysis of the severity of the valve lesion. MAIN TEXT In this review, the fundamentals of CMR in assessment of VHD are described, together with its strengths and weaknesses. We detail the utility of CMR for studying all aspects of VHD, including valve anatomy, flow quantification as well as ventricular volumes and function. The optimisation of CMR for evaluating the commonest valve lesions (aortic stenosis, aortic regurgitation, mitral regurgitation, mitral stenosis) as well as in right-sided VHD and prosthetic valves is summarised. The focus of this review is to enable the reader to optimise the use of CMR in his or her own evaluation of heart valve lesions in clinical practice. CONCLUSIONS CMR can be used for the comprehensive evaluation of VHD. This exciting, non-invasive imaging modality is likely to have increasing utility in the clinical evaluation of patients with VHD.

Valve stress echocardiography (VSE) can be performed as exercise stress echocardiography (ESE) or dobutamine stress echocardiography (DSE) depending on the patient’s clinical status, severity and type of valve disease. ESE combines exercise testing with two-dimensional grey scale and Doppler echocardiography during exercise. Thus, it provides objective assessment of symptomatic status (exercise test), as well as exercise-induced changes of a series of echocardiographic parameters (different depending on the valve disease type), which yield prognostic information in individual patients and help in a better treatment planning. DSE is useful in symptomatic patients with low-gradient aortic stenosis. It clarifies its severity and helps in assessing surgical risk in patients with severe disease and systolic dysfunction. It can be also used to test valve haemodynamics in asymptomatic patients with significant mitral stenosis unable to perform an exercise test or to test the left ventricle response, namely to test viability, in patients with ischaemic secondary mitral regurgitation. VSE has taught us that history taking, clinical examination and resting echocardiography give an ‘incomplete picture’ of the disease in patients presenting with a severe valve disease. Therefore, its use should be encouraged in such patients.

Abstract
BACKGROUND A comprehensive evaluation of mitral stenosis (MS) severity commonly utilizes two-dimensional (2D) echocardiography techniques. However, the complex three-dimensional (3D) structure of the mitral valve (MV) poses challenges to accurate measurements of its orifice area by 2D imaging modalities. We aimed to assess MS severity by comparing measurements of the MV orifice area using conventional echocardiography methods to 3D orifice area (3DOA), a novel echocardiographic technique which minimizes geometric assumptions. METHODS Routine 2D and 3D intraoperative transesophageal echocardiographic images from 26 adult cardiac surgery patients with at least moderate rheumatic MS were retrospectively reviewed. Measurements of the MV orifice area obtained by pressure half-time (PHT), proximal isovelocity surface area (PISA), continuity equation, and 3D planimetry were compared to those acquired using 3DOA. RESULTS MV areas derived by PHT, PISA, continuity equation, 3D planimetry, and 3DOA (mean value ± standard deviation) were 1.12 ± 0.27, 1.03 ± 0.27, 1.16 ± 0.35, 0.97 ± 0.25, and 0.76 ± 0.21 cm, respectively. Areas obtained from the 3DOA method were significantly smaller than areas derived from PHT (mean difference 0.35 cm, P < .0001), PISA (mean difference: 0.28 cm, P = .0002), continuity equation (mean difference: 0.43 cm, P = .0015), and 3D planimetry (mean difference: 0.19 cm, P < .0001). MV 3DOAs also identified a significantly greater percentage of patients with severe MS (88%) compared to PHT (31%, P = .006), PISA (42%, P = .01), and continuity equation (39%, P = .017) but not in comparison to 3D planimetry (62%, P = .165). CONCLUSIONS Novel measures of the stenotic MV 3DOA in patients with rheumatic heart disease are significantly smaller than calculated values obtained by conventional methods and may be consistent with a higher incidence of severe MS compared to 2D techniques. Further investigation is warranted to determine the clinical relevance of 3D echocardiographic techniques used to measure MV area.

Abstract
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. RESULTS In the Swedish population (n=10 164 211), the incidence of VHD was 63.9 per 100 000 person-years, with aortic stenosis (AS; 47.2%), mitral regurgitation (MR; 24.2%) and aortic regurgitation (AR; 18.0%) contributing most of the VHD diagnoses. The majority of VHDs were diagnosed in the elderly (68.9% in subjects aged ≥65 years), but pulmonary valve disease incidence peaked in newborns. Incidences of AR, AS and MR were higher in men who were also more frequently diagnosed at an earlier age. Mitral stenosis (MS) incidence was higher in women. Rheumatic fever was rare. Half of AS cases had concomitant atherosclerotic vascular disease (48.4%), whereas concomitant heart failure and atrial fibrillation were common in mitral valve disease and tricuspid regurgitation. Other common comorbidities were thoracic aortic aneurysms in AR (10.3%), autoimmune disorders in MS (24.5%) and abdominal hernias or prolapse in MR (10.7%) and TR (10.3%). CONCLUSIONS Clinically diagnosed VHD was primarily a disease of the elderly. Rheumatic fever was rare in Sweden, but specific VHDs showed a range of different comorbidity profiles . Pronounced sex-specific patterns were observed for AR and MS, for which the mechanisms remain incompletely understood.

Abstract
BACKGROUND In patients with mitral stenosis (MS), pulmonary hypertension (PH) is a significant contributor to the associated morbidity. We aimed to study factors associated with the presence of significant PH (sPH) and whether incorporating body surface area (BSA) in the mitral valve area (MVA) would improve the predictive value of the latter. METHODS The medical records of 558 patients with severe MS undergoing percutaneous balloon mitral commissurotomy were evaluated over a period of 8 years. Factors associated with the presence of significant PH (sPH) defined as mPAP ≥ 40 mm Hg were examined. RESULTS A total of 558 patients (423 women) were enrolled. Overall, 153 (27%) patients had sPH. Patients with sPH were similar to the rest of the subjects in terms of demographics, body habitus, blood group, and incidence of atrial fibrillation. Among echocardiographic findings, absolute MVA, indexed MVA, and mean transmitral valve gradient were associated with the presence of sPH. Transmitral valve gradient during right heart catheterization had the highest area under the curve for an association with sPH. CONCLUSION Age, gender, heart rhythm, and blood group were not associated with the presence of sPH in severe MS. The predictive value of the indexed MVA for the presence of sPH was not higher than that of absolute MVA.

Abstract
The majority of proteomic studies have focused on identifying atrial fibrillation (AF)-associated proteins in the right atrium (RA), thus potential differences in AF-associated proteins between the RA and left atrium (LA) remain unknown. The aim of the present study was to perform proteomic analysis to compare the potential differences in AF-associated proteins between the right atrial appendage (RAA) and left atrial appendage (LAA) in patients with rheumatic mitral valve disease (RMVD). RAA and LAA tissues were obtained from 18 patients with RMVD (10 with AF) during mitral valve replacement surgery. Two-dimensional fluorescence difference gel electrophoresis (2-D DIGE) proteomics analysis was performed using these tissues to identify AF-associated proteins in RAA and LAA. Subsequently, the proteomics data was validated using western blot analysis of nine selected proteins. In RAA, 32 AF-associated proteins were significantly dysregulated (15 upregulated and 17 downregulated). In LAA, 31 AF-associated proteins were significantly dysregulated (13 upregulated and 18 downregulated). Among these AF-associated proteins, 17 were AF-associated in both RAA and LAA, 15 were AF-associated only in RAA, and 14 were AF-associated only in LAA. Amongst the differentially expressed proteins, western blot analysis validated the results for 6 AF-associated proteins, and demonstrated similar distributions in RAA and LAA compared with the 2-D DIGE results. Of these proteins, 2 proteins were AF-associated in both RAA and LAA, 2 were AF-associated only in RAA, and 2 were AF-associated only in LAA. Additionally, the different distributions of AF-associated proteins in the RAA and LAA of patients with RMVD was analyzed, which may reflect the different regulatory mechanisms of the RA and LA in AF. These findings may provide new insights into the underlying molecular mechanisms of AF in patients with RMVD.

Abstract
The important roles of microRNAs (miRNAs) in the pathological process of the cardiovascular system have been recognized. However, identification of miRNAs related to valvular heart disease with atrial fibrillation (AF-VHD) has been difficult and very slow because of complex pathological mechanism of AF-VHD. Analysis of microarray expression profiles provides the possibility to rapid prediction of disease-regulating miRNAs and can lay a theoretical foundation for further experimental studies. A computational method is proposed to predict AF-VHD-specific miRNAs by combining miRNA and gene expression data, which are strongly correlated. Using the proposed method, a 45-miRNA AF-VHD-specific signature is predicted. Compared with other related results, 15 of 45 miRNAs are the same and the rest 30 miRNAs are different. Our analysis shows that 11 of 30 new miRNAs are associated with the diseases inducing AF-VHD and the remaining 19 miRNAs have good combinational discrimination power. Therefore, the AF-VHD signature we have predicted is confirmed to be reliable and specific. In a word, this study proposes an effective computational strategy in prediction of disease-regulating miRNAs and finds some AF-VHD-specific miRNAs, which provides new insight into the further experimental study and molecular mechanism leading to the development of AF-VHD.

Abstract
Objective: Little information is available about echocardiographic progression of mitral stenosis (MS). The aim of this study was to investigate whether the left ventricular (LV) strain is a favorable method predicting the progression of MS. Methods: Forty-eight patients with isolated mild-to-moderate MS were enrolled in this prospective cohort study. LV global longitudinal strain (GLS) and strain rate (GLSR) were measured by two-dimensional echocardiography (2-DE) at the baseline. Mitral valve area (MVA) was evaluated during the 5-year follow-up. The change in MVA from the beginning to the end of the surveillance period was determined as an indicator of progression. Pearson’s correlation test was used, and significant differences between the groups were analyzed using the Student’s t-test or the Mann–Whitney U test. At the end of follow-up, we evaluated the correlation between the change in MVA and both GLS-GLSR. GLS and GLSR are predictive factors for MS progression, whether or not it has been tested according to the receiver operating characteristics curve analysis. Results: A meaningful correlation was detected between the change in MVA with both GLS and GLSR (r=0.924 and r=0.980, respectively, p<0.001). The cut-off value for GLS was identified as –16.98 (sensitivity 81%, specificity 96%, p<0.001) and for GLSR as –1.45 (sensitivity 95%, specificity 100%, p<0.001). Patients with MS having a value under (mathematically above) these cut-off values showed more rapid progression. Conclusion: The progression of MS can be predicted by GLS and GLSR measurements, which are evaluated via strain echocardiography. (Anatol J Cardiol 2016; 16: 772-7)
