AIM: The aim of this study was to assess preoperative determinants, prevalence, and prognostic impact of left ventricular (LV) reverse remodeling (LVRR) in patients with secondary mitral regurgitation (SMR), undergoing MitraClip implantation (MCi). METHODS: From March 2012 to January 2015, a total of 41 consecutive patients with moderate-to-severe SMR treated successfully with MCi were enrolled. All patients underwent clinical and echocardiographic follow-up after MCi. Global longitudinal strain (GLS) was obtained using two dimensional speckle tracking analysis. A reduction in LV end-systolic volume more than 10% compared with baseline was considered as a marker of LVRR. Patients were divided into two groups according to the presence or absence of LVRR. Cardiac events were defined as the occurrence of cardiac death, rehospitalization for worsening heart failure, and mitral valve surgery. RESULTS: On univariable analysis, EuroSCORE II and GLS were associated with LVRR. On multivariable logistic regression analysis, GLS was the only independent correlate of LVRR (P = 0.004). A receiver operating characteristic curve identified a cutoff value for GLS of -9.25% (P < 0.001) associated with LVRR, with a sensitivity and specificity of 81 and 74%, respectively. New York Heart Failure Association class more than 2 after MCi, absence of LVRR after MCi, and preoperative GLS more than -9.25% were significantly correlated with adverse cardiac events at long-term follow-up. On multivariable logistic regression analysis, GLS was the only independent predictor of composite adverse cardiac events at 2-year follow-up. CONCLUSION: A worse preoperative GLS predicts no LVRR and is associated with adverse long-term outcome after successful MCi for SMR. [less ▲]

Aims To obtain the normal ranges for 2D echocardiographic (2DE) measurements of left ventricular (LV) strain from a large group of healthy volunteers accounting for age and gender. Methods and results A total of 549 (mean age: 45.6 ± 13.3 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. 2DE data sets have been analysed with a vendor-independent software package allowing homogeneous measurements irrespective of the echocardiographic equipment used to acquire the data sets. The lowest expected values of LV strains and twist calculated as ± 1.96 standard deviations from the mean were −16.7% in men and −17.8% in women for longitudinal strain, −22.3% and −23.6% for circumferential strain, 20.6% and 21.5% for radial strain, and 2.2 degrees and 1.9 degrees for twist, respectively. In multivariable analysis, longitudinal strain decreased with age whereas the opposite occurred with circumferential and radial strain. Male gender was associated with lower strain for longitudinal, circumferential, and radial strain. Inter-vendor differences were observed for circumferential and radial strain despite the use of vendor-independent software. Importantly, no intervendor differences were noted in longitudinal strain. Conclusion The NORRE study provides contemporary, applicable 2D echocardiographic reference ranges for LV longitudinal, radial, and circumferential strain. Our data highlight the importance of age- and gender-specific reference values for LV strain. [less ▲]

BACKGROUND: Modifications in left atrial (LA) flow velocities after left atrial appendage (LAA) exclusion have been shown in animal and ex vivo models. In a substudy of PROTECT AF (Percutaneous Closure of the Left Atrial Appendage Versus Warfarin Therapy for Prevention of Stroke in Patients With Atrial Fibrillation), an objective improvement in quality of life was observed after LAA closure. OBJECTIVE: The purpose of this study was to investigate the impact of LAA closure on LA transport function. METHODS: Comprehensive transthoracic echocardiography evaluation (2-dimensional [2D]/3-dimensional [3D], 2D speckle tracking) was prospectively performed before and after LAA closure (at discharge and 45 days after procedure) in 33 patients. RESULTS: LAA closure was associated with a significant improvement in LA reservoir function at discharge and 45 days after the procedure with (1) increased maximum LA volume index, (2) increased 2D-LA reservoir volume and expansion index, and (3) increased 2D speckle tracking-derived peak atrial longitudinal strain (PALS) (27.9 ± 14 and 26 ± 12.6 vs 21.7 ± 10.7%, P <.0001). LAA closure was also associated with a significant improvement in LA contractile function with (1) increased LA ejection fraction and (2) increased speckle tracking-derived peak atrial contraction strain (PACS) in sinus rhythm patients (19.1 ± 6.8 and 18.1 ± 5.4 vs 14.4 ± 6.4%, P = .0006). Conversely, the slope of the relation between PACS and PALS remained unchanged (0.5 ± 0.27 and 0.53 ± 0.3 vs 0.5 ± 0.25, P = .99), thus arguing for an improvement in LA contractile function secondary to a Frank-Starling effect rather than a modification in its intrinsic contractility. CONCLUSION: LAA closure was associated with an improvement in LA mechanical function. These changes appeared to be related to a modification in loading conditions, that is, a Frank-Starling effect.

Aim: To obtain the normal ranges for 3D echocardiography (3DE) measurement of left ventricular (LV) volumes, function, and strain from a large group of healthy volunteers. Methods and results: A total of 440 (mean age: 45 ± 13 years) out of the 734 healthy subjects enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study had good-quality 3DE data sets that have been analysed with a vendor-independent software package allowing homogeneous measurements regardless of the echocardiographic machine used to acquire the data sets. Upper limits of LV end-diastolic and end-systolic volumes were larger in men (97 and 42 mL/m2) than in women (82 and 35 mL/m2; P < 0.0001). Conversely, lower limits of LV ejection fraction were higher in women than in men (51% vs. 50%; P < 0.01). Similarly, all strain components were higher in women than in men. Lower range was -18.6% in men and -19.5% in women for 3D longitudinal strain, -27.0% and -27.6% for 3D circumferential strain, -33.2% and -34.4% for 3D tangential strain and 38.8% and 40.7% for 3D radial strain, respectively. LV volumes decreased with age in both genders (P < 0.0001), whereas LV ejection fraction increased with age only in men. Among 3DE LV strain components, the only one, which did not change with age was longitudinal strain. Conclusion: The NORRE study provides applicable 3D echocardiographic reference ranges for LV function assessment. Our data highlight the importance of age- and gender-specific reference values for both LV volumes and strain. [less ▲]

OBJECTIVES: Bicuspid aortic valve (BAV) is frequently associated with aortic insufficiency (AI) due to cusp disease and/or aortic root dilatation. Based on functional classification and morphology, a systematic surgical approach was used for aortic valve repair (AVr). METHODS: : From 2004 to 2014, 152 consecutive patients (mean age 55 ± 7 years) with BAV underwent AVr with or without concomitant aortic root surgery. Cusp pathology was treated with central plication in 60 (39.5%) patients, free edge reinforcement in 45 (29.6%), triangular resection in 28 (18.4%) and pericardial patch in 19 (12.5%). Aortic root dilatation was corrected with valve sparing reimplantation in 65 patients. Mean follow-up was 68 ± 36 months. RESULTS: : In-hospital death was 1.3%. Overall 5-year survival was 88.6 ± 3.6%. Freedom from recurrent ≥ grade 2 AI requiring reoperation at 5-year was 93 ± 3.1%. Five-year freedom from reintervention was 98.4 ± 1.6%, 93.3 ± 6.4% and 82.6 ± 9.6 in the group of patients treated with AVr and reimplantation technique, AVr and subcommissural plasty and AVr repair alone (log-rank P  = 0.005). Commissural orientation <160°, type 2 Siever's BAV and preoperative annulus diameter >29 mm were identified as predictors for recurrent ≥ grade 2 AI. CONCLUSIONS: : BAV repair could be achieved with low incidence of recurrent AI, especially when concomitant annulus stabilization was performed. Systematic preoperative morphological and functional characteristics of the aortic valve should be carried out in order to reduce the risk of repair failure. [less ▲]

A unique and highly versatile technique, stress echocardiography (SE) is increasingly recognized for its utility in the evaluation of non-ischaemic heart disease. SE allows for simultaneous assessment of myocardial function and haemodynamics under physiological or pharmacological conditions. Due to its diagnostic and prognostic value, SE has become widely implemented to assess various conditions other than ischaemic heart disease. It has thus become essential to establish guidance for its applications and performance in the area of non-ischaemic heart disease. This paper summarizes these recommendations. [less ▲]

Arrhythmogenic cardiomyopathy (AC) is a progressive disease with high risk of life-threatening ventricular arrhythmias. A genetic mutation is found in up to 50-60% of probands, mostly affecting desmosomal genes. Diagnosis of AC is made by a combination of data from different modalities including imaging, electrocardiogram, Holter monitoring, family history, genetic testing, and tissue properties. Being a progressive cardiomyopathy, repeated cardiac imaging is needed in AC patients. Repeated imaging is important also for risk assessment of ventricular arrhythmias. This expert consensus document gives clinical recommendations for how to use multi-modality imaging in the different aspects of AC disease, including diagnosis, family screening, follow-up, risk assessment, and differential diagnosis.

OPINION STATEMENT: Mitral valve disease represented by mitral stenosis and mitral regurgitation is the second most frequent valvulopathy. Mitral stenosis leads to an increased left atrial pressure whereas mitral regurgitation leads to an increased left atrial pressure associated with a volume overload. Secondary to an upstream transmission of this overpressure, both mitral stenosis and regurgitation lead to pulmonary hypertension and right heart failure. In addition, mitral regurgitation also leads to left ventricular dilatation and dysfunction with left heart failure. Depending on the anatomy of the valvular and subvalvular apparatus, valve repair (percutaneous mitral commissurotomy for mitral stenosis and valvuloplasty for mitral regurgitation) might be possible. If the anatomy is not favorable, valve replacement by mechanical or biological prosthesis is indicated. Most of the intervention indications are based on clinical symptoms and resting transthoracic echocardiography. Outcomes of patients operated based upon resting echo abnormalities might however not be optimal. Therefore early intervention might be beneficial based upon abnormal exercise testing, which has been demonstrated to more sensitive to identify high-risk patients. In this last decade, especially exercise echocardiography has been found to be a crucial tool in the management of patients with mitral valve disease. [less ▲]

BACKGROUND: Objective assessment of maximal aerobic capacity using peak oxygen consumption (peak VO2) can be helpful in the management of patients with asymptomatic aortic stenosis (AS). The relationship between peak VO2 and AS severity criteria derived from rest and supine exercise echocardiography (SEE) has never been explored. OBJECTIVES: We aimed to determine whether low peak VO2 (<85% of predicted value) is associated with severity parameters in SEE, and poor clinical outcome. METHODS: Fifty one asymptomatic patients (mean age of 54+/-21years) with moderate to severe aortic stenosis (Vmax>3m/s) and left ventricle ejection fraction>50% prospectively underwent resting and SEE and cardiopulmonary exercise testing (CPX). RESULTS: Peak VO2 was lower than expected (21.9+/-7.4mL/kg/min), i.e. <85% of predicted value in 57% patients, secondary to cardiac limitation in most of them (69%). In multiple regression analysis, age, BMI and female gender were the only independent determinants of peak VO2. Interestingly no parameter derived from SEE was associated with peak VO2. After 21+/-7month follow-up, no patient died, 20 underwent cardiac surgery. Peak VO2<85% of predicted value was associated with lower event free survival compared to normal peak VO2 (57%+/-11% vs 93+/-6%, p=0.036) whereas no exercise echocardiographic parameter could predict such events. Peak VO2>/=85% had a negative predictive value of 97%. CONCLUSION: CPX detects a high proportion of false asymptomatic AS patients with poorer outcome that cannot be predicted by SEE markers of AS severity. Assessment of aerobic capacity should be part of current approach within a "watchful waiting" strategy. [less ▲]

BACKGROUND: Left ventricular outflow tract (LVOT) measurement is a critical step in the quantification of aortic valve area. The assumption of a circular morphology of the LVOT may induce some errors. The aim of this study was to assess the three-dimensional (3D) morphology of the LVOT and its impact on grading aortic stenosis severity. METHODS: Fifty-eight patients with aortic stenosis were studied retrospectively. LVOT dimensions were measured using 3D transesophageal echocardiography at three levels: at the hinge points (HP) of the aortic valve and at 4 and 8 mm proximal to the annular plane. Results were compared with standard two-dimensional echocardiographic measurements. RESULTS: Three-dimensional transesophageal echocardiography showed a funnel shape that was more circular at the HP and more elliptical at 4 and 8 mm proximal to the annular plane (circularity index = 0.92 vs 0.83 vs 0.76, P < .001). Cross-sectional area was smaller at the HP and larger at 4 and 8 mm from the annular plane (3.6 vs 3.9 vs 4.1 cm2, P = .001). The best correlation between two-dimensional and 3D transesophageal echocardiographic dimensions was at the HP (intraclass correlation coefficient = 0.75; 95% CI, 0.59-0.86). When the HP approach was selected, there was a reduction in the percentage of patients with low flow (from 41% to 29%). CONCLUSIONS: A large portion of patients with aortic stenosis have funnel-shaped and elliptical LVOTs, a morphology that is more pronounced in the region farther from the annular plane. Two-dimensional LVOT measurement closer to the annular plane has the best correlation with 3D measurements. Measurement of the LVOT closer to the annular plane should be encouraged to reduce measurement errors. [less ▲]

Inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis, are characterised by aberrant immunological responses leading to chronic inflammation without tissue regeneration. These two diseases are considered distinct entities, and there is some evidence that neutrophil behaviour, above all other aspects of immunity, clearly separate them. Neutrophils are the first immune cells recruited to the site of inflammation, and their action is crucial to limit invasion by microorganisms. Furthermore, they play an essential role in proper resolution of inflammation. When these processes are not tightly regulated, they can trigger positive feedback amplification loops that promote neutrophil activation, leading to significant tissue damage and evolution toward chronic disease. Defective chemotaxis, as observed in Crohn's disease, can also contribute to the disease through impaired microbe elimination. In addition, through NET production, neutrophils may be involved in thrombo-embolic events frequently observed in IBD patients. While the role of neutrophils has been studied in different animal models of IBD for many years, their contribution to the pathogenesis of IBD remains poorly understood, and no molecules targeting neutrophils are used and validated for the treatment of these pathologies. Therefore, it is crucial to improve our understanding of their mode of action in these particular conditions in order to provide new therapeutic avenues for IBD. [less ▲]

Since the 1990's cabergoline has been the treatment of choice in prolactinoma, as it permits rapid and effective hormonal and tumor control in most cases. Evidence of cardiac valvulopathy was demonstrated in Parkinson's disease patients treated with dopamine agonists. Retrospective studies in prolactinoma patients treated with cabergoline at lower doses did not show such an effect. However, few prospective data with long-term follow-up are available. The aim of this study was to assess the safety of cabergoline regarding cardiac valvular status during prospective follow-up in patients treated for prolactinoma or idiopathic hyperprolactinemia. We report here a series of 100 patients (71F; median age at diagnosis: 41.5 years) treated with cabergoline for endocrine diseases (prolactinoma n = 89, idiopathic hyperprolactinemia n = 11). All patients underwent complete transthoracic echocardiographic studies at baseline and during long-term prospective surveillance using the same equipment and performed by the same technicians. The median interval between baseline and last follow-up echocardiographic studies while on cabergoline was 62.5 months (interquartile range: 34.75-77.0). The median total duration of cabergoline treatment was 124.5 months (interquartile range: 80.75-188.75) and the median cumulative total dose of cabergoline was 277.8 mg (interquartile range : 121.4-437.8 mg) at last follow-up. We found no clinically relevant alterations in cardiac valve function or valvular calcifications with cabergoline treatment. Our data suggest that findings from retrospective analyses are correct and that cabergoline is a safe chronic treatment at the doses used typically in endocrinology. [less ▲]
