Systolic longitudinal global and segmental myocardial mechanics in symptomatic isolated left ventricular non-compaction cardiomyopathy.

BACKGROUND: Left ventricular (LV) non-compaction cardiomyopathy (LV-NC) is rare, and data of segmental myocardial mechanics are largely lacking. We investigated myocardial longitudinal mechanics in adults with symptomatic LV-NC (n = 30) versus individuals with healthy hearts (n = 150). The contribution of compacted and non-compacted myocardial layer to systolic LV function has to be determined. METHODS: Seven parameters derived from speckle tracking echocardiography were evaluated and documented utilizing polar-diagrams to obtain overviews of myocardial mechanics of the entire LV. RESULTS: According to embryonal myocardial development, non-compacted myocardium was mostly located in mid-ventricular and apical segments of the free LV wall. LV ejection fraction was reduced in LV-NC (34 ± 15%, healthy 63 ± 5%, P < .0001). The compact wall layer in LV-NC demonstrated increasing systolic radial thickness (diastolic 5.6 ± 1.4, systolic 6.5 ± 1.4mm, P = .016), whereas the non-compacted layer remained unchanged or tended to decrease in thickness (diastolic 17.6 ± 5.3, systolic 16.0 ± 4.6mm, P = .22). Compared with heart-healthy individuals in LV-NC peak systolic longitudinal strain (healthy -21.1% vs. LV-NC -8.8, P < .0001), peak systolic longitudinal strain-rate (-1.23%/s vs. -0.64, P < .0001), and peak longitudinal displacement (12.1 vs. 5.6 mm, P < .0001) were reduced, while pre-systolic stretch index (1.31% vs. 3.2%, P < .0001) and post-systolic index (2.5% vs. 15.9%, P < .0001) increased. Time-to-peak longitudinal strain (371 vs. 389 ms, P = .065) and time-to-peak longitudinal strain rate (181 vs. 200 ms, P = .0677) did not differ significantly. In LV-NC, there were no significant differences between analyses using an interpolated endocardial border along the edges of the recesses and the endocardial edge of the compact wall layer. Hence, LV function appeared to depend only on the thin compact wall layer. CONCLUSION: In LV-NC, myocardial efficiency is severely diminished compared with healthy controls and LV function seemed to depend mainly on the compact myocardial wall layer.

Recommendations for participation in competitive sport in adolescent and adult athletes with Congenital Heart Disease (CHD): position statement of the Sports Cardiology & Exercise Section of the European Association of Preventive Cardiology (EAPC), the European Society of Cardiology (ESC) Working Group on Adult Congenital Heart Disease and the Sports Cardiology, Physical Activity and Prevention Working Group of the Association for European Paediatric and Congenital Cardiology (AEPC).

Improved clinical care has led to an increase in the number of adults with congenital heart disease (CHD) engaging in leisure time and competitive sports activities. Although the benefits of exercise in patients with CHD are well established, there is a low but appreciable risk of exercise-related complications. Published exercise recommendations for individuals with CHD are predominantly centred on anatomic lesions, hampering an individualized approach to exercise advice in this heterogeneous population. This document presents an update of the recommendations for competitive sports participation in athletes with cardiovascular disease published by the Sports Cardiology & Exercise section of the European Association of Preventive Cardiology (EAPC) in 2005. It introduces an approach which is based on the assessment of haemodynamic, electrophysiological and functional parameters, rather than anatomic lesions. The recommendations provide a comprehensive assessment algorithm which allows for patient-specific assessment and risk stratification of athletes with CHD who wish to participate in competitive sports.

Recommendations for participation in competitive and leisure time sport in athletes with cardiomyopathies, myocarditis, and pericarditis: position statement of the Sport Cardiology Section of the European Association of Preventive Cardiology (EAPC).

Myocardial diseases are associated with an increased risk of potentially fatal cardiac arrhythmias and sudden cardiac death/cardiac arrest during exercise, including hypertrophic cardiomyopathy, dilated cardiomyopathy, left ventricular non-compaction, arrhythmogenic cardiomyopathy, and myo-pericarditis. Practicing cardiologists and sport physicians are required to identify high-risk individuals harbouring these cardiac diseases in a timely fashion in the setting of preparticipation screening or medical consultation and provide appropriate advice regarding the participation in competitive sport activities and/or regular exercise programmes. Many asymptomatic (or mildly symptomatic) patients with cardiomyopathies aspire to participate in leisure-time and amateur sport activities to take advantage of the multiple benefits of a physically active lifestyle. In 2005, The European Society of Cardiology (ESC) published recommendations for participation in competitive sport in athletes with cardiomyopathies and myo-pericarditis. One decade on, these recommendations are partly obsolete given the evolving knowledge of the diagnosis, management and treatment of cardiomyopathies and myo-pericarditis. The present document, therefore, aims to offer a comprehensive overview of the most updated recommendations for practicing cardiologists and sport physicians managing athletes with cardiomyopathies and myo-pericarditis and provides pragmatic advice for safe participation in competitive sport at professional and amateur level, as well as in a variety of recreational physical activities.

Recommendations for participation in competitive sports of athletes with arterial hypertension: a position statement from the sports cardiology section of the European Association of Preventive Cardiology (EAPC).

Current guidelines of the European Society of Cardiology advocate regular physical activity as a Class IA recommendation for the prevention and treatment of cardiovascular disease. Despite its undisputed multitude of beneficial effects, competitive athletes with arterial hypertension may be exposed to an increased risk of cardiovascular events. This document is an update of the 2005 recommendations and will give guidance to physicians who have to decide on the risk of an athlete during sport participation.

Physiological left ventricular segmental myocardial mechanics: Multiparametric polar mapping to determine intraventricular gradients of myocardial dynamics.

OBJECTIVE: We investigated physiological systolic left ventricular (LV) myocardial mechanics and gradients to provide a database for later studies of diseased hearts. METHODS: The analyses were performed in 131 heart-healthy individuals and included seven parameters of myocardial mechanics using speckle tracking echocardiography (STE). RESULTS: Basal to apical and circumferentially significant physiological intraventricular parameter gradients of myocardial activity were determined. Global mean values and segmental ranges were peak systolic longitudinal strain -21.2 ± 3.3%, 95% confidence interval [CI] -21.8% to -20.6%), gradient (basal to apical) -16.0% to -26.7%; peak systolic longitudinal strain rate -1.24 ± 0.31%/s, 95% CI -1.29% to -1.19%/s, gradient (basal to apical) -0.91% to -1.61%/s; post-systolic index 2.6 ± 3.2%, 95% CI 3.15%-2.05%, gradient (basal/medial/apical) 7.0/1.2/2.4%; pre-systolic stretch index 1.3 ± 2.7%, 95% CI 1.77%-0.83%, gradient (basal/medial/apical) 6.5/0.2/1.3%; peak longitudinal displacement 12.2 ± 2.6 mm, 95% CI 12.6-11.8 mm, gradient (basal to apical) 21.0-3.4 mm; time-to-peak longitudinal strain 370 ± 43 ms, 95% CI 377-363 ms, gradient (basal to apical) 396-361 ms; and time-to-peak longitudinal strain rate 180 ± 47 ms, 95% CI 188-172 ms, gradient (basal to apical) 150-200 ms. CONCLUSION: This study generated a database of seven STE-derived parameters of physiological segmental and global myocardial LV mechanics. The resulting sets of three-dimensional intraventricular mappings of the entire LV provide physiological parameter gradients in baso-apical and circumferential direction by applying the 17-segment polar model. This will facilitate comparison of systolic myocardial activity of the healthy LV with diseased or otherwise altered (eg, sports) hearts.

Echocardiographically derived effective valve opening area in mitral prostheses: a comparative analysis of various calculations using continuity equation and pressure half time method.

Detection of dysfunctional mitral valve prostheses (MP) remains complex even though being optimized by considering echocardiographically derived prosthetic effective orifice area (VA). The purpose was to compare VA in MP, calculated by the continuity equation (CE) using peak velocities (CEVpeak), mean velocities (CEVmean), velocity-time integrals (CEVTI) and the pressure half time method using 220 ms as constant first (PHT220) as well as optimized constants. In 267 consecutive patients with normally functioning MP, we investigated VA within the first postoperative month. With increasing prosthetic sizes, mean VA values also increase in all calculations. The statistical curves demonstrate no significant difference in graphical steepness but show different levels. Comparison of mean VA showed the known systematic higher values of PHT220 and significantly decreased results when using CEVTI. This systematic difference between mean VA applying PHT220 versus CEVTI is approximately 1.0 cm(2) for all prosthetic sizes. Calculations via CEVpeak were close to the results of CEVTI. CEVmean produced values, which graphically correspond to the PHT220 curve. Only PHT220 detected the constructional equal prosthetic inner ring width between 29 and 31 mm. To compensate the systematic difference between CEVTI and PHT220, an optimized constant of 140 ms was calculated to be applied in PHT (PHT140). VA is a robust and, therefore, preferable parameter for investigating MP. If needed, both CE and PHT are applicable with a systematical difference between CEVTI and PHT220. An optimized constant of 140 ms (PHT140) should be applied when calculating VA of mitral valve prostheses via PHT.

A differentiated morphological parameter-coding system to describe the suitability of mitral valve stenoses intended for percutaneous valvotomy.

Percutaneous balloon-mitral-valvotomy (PBMV) is an alternative to surgery in selected patients with mitral valve (MV) stenosis (MS). Applying echocardiography, suitability for PBMV is assessed by detailed morphological description. Echo-scores alone are suboptimal to describe MV morphology, because single parameters, important for a decision concerning PBMV, are not distinguishable out of a score number. The aim was to design a tool (coding-system), which combines a number for a stenotic MV like scores (for statistical options) and decodable, generally applied parameters describing the MS morphology. The reproducibility of the MS morphology using the coding-system has to be tested in 90 patients. A separate group of 297 patients (pts) with MS, scheduled for PBMV, should be investigated prospectively applying the coding-system and a comparable score. We chose the Wilkins score (WS) as representative of scores. The coding-system is designed as a parameter sequencing set consisting of 6 digits. The first digit indicates a decision code concerning suitability for PBMV. The following 5 digits indicate generally accepted morphological parameters, which are partially also used in the WS. Therefore, the MS morphology can be "read" retrospectively by decoding. 201/297 patients were found suitable for PBMV. Applying the coding-system all 201 suitable patients were correctly distinguished from 96 morphologically unsuitable patients. Astonishingly 48/96 of the rejected patients showed a WS ≤8 whereas 28/201 of the suitable patients demonstrated a WS >8. 25/28 of them showed a successful initial outcome. Applying the generally known threshold of "8" when predicting suitability of a MS, the WS demonstrated an initial success rate of 62 %, sensitivity of 0.87, specificity of 0.45, precision of 0.79, and accuracy of 0.78. Applying the coding-system, the initial success rate was 70.8 %, sensitivity = 0.96, specificity = 1.0, precision = 1.0, and accuracy = 0.97. The coding-system is an advanced diagnostic aid, is statistically applicable, offers a decodable morphological description, includes a decision code regarding suitability for PBMV, and can be used for comparing different groups of patients with MS by calculating "mean morphologies" of groups.

Left ventricular dyssynchrony predicts clinical response to CRT - a long-term follow-up single-center prospective observational cohort study.

BACKGROUND: Until now, there is no consensus regarding the definition of a clinical response to cardiac resynchronization therapy (CRT) in patients with chronic heart failure (CHF) and systolic left ventricular (LV) dysfunction. The aim of this study was to evaluate if echocardiography is predictive for an objective improvement in exercise capacity during long-term follow-up of CRT. METHODS: Each patient underwent echocardiography and spiroergometry both at baseline and at last follow-up. Left ventricular dyssynchrony (LVD) before CRT was defined by tissue Doppler imaging (TDI) as intra-LV delay ≥40 msec (septal-lateral or anterior-posterior). Clinical response to CRT was defined as increase of peakVO2 or as increase of maximal workload >10% as compared to baseline. RESULTS: Mean follow-up was 69 ± 37 months. From the 238 consecutive patients included in the study, 141 (59%) were classified as clinical responders and 97 (41%) as nonresponders. Baseline data of responders and nonresponders were comparable. However, clinical responders showed more often LVD (64%) than nonresponders (42%, P = 0.004). On multivariate regression analysis, nonischemic origin of CHF (ß-coefficient in the final model 0.1, P = 0.04) and LVD at baseline (ß-coefficient in the final model 0.2, P < 0.001) were independently associated with clinical response during long-term follow-up. Patients with LVD at baseline had significant more often an improvement of left ventricular ejection fraction >10% (P = 0.02) and a reduction of left ventricular end-diastolic diameter (LVEDD) >10% (P < 0.01) than patients without LVD at baseline. CONCLUSIONS: LVD at baseline as assessed by a straightforward echocardiographic approach predicts the long-term clinical response to CRT and is associated with a more pronounced reverse LV remodeling.

Elite athletes with mitral or aortic regurgitation and their cardiopulmonary capability.

BACKGROUND: Aortic or mitral valvular regurgitation (left cardiac valvular regurgitation, LCVR) of less than second-degree (< degree II) occasionally found in competitive athletes is of questionable relevance. Precisely detectable by echocardiography there is scarce published data that clarifies cardiopulmonary capacity or any limitations LCVR < degree ll may cause. METHODS: In this single-centre study we consecutively recruited highly trained athletes (n= 14) with LCVR < degree ll detected in 2D echo. Not included were athletes with multi- or right-cardiac valvular dysfunction and structural heart disease other than bicuspid aortic valve or mitral valve prolaps. Target parameters were determined by 2D echo and spiroergometry. RESULTS: There were no significant differences with regard to age and body mass index. Echocardiographically determined muscle mass index was increased in both groups (134 14.7 vs 129.6+/-27.5; P=0.69), whereas the left-ventricular end-diastolic diameter index was significant higher in the LCVR < degree II group (27.3 +/- 1.3 vs 25.2 +/- 2.4; P = 0.04). However, there were no significant differences with regard to (oxygen uptake) V02, at baseline (athletes with LCVR < degree II 5.7 +/- 0.9 vs controls 5 +/- 0.96, P= 0.06), at the anaerobic threshold (athletes with LCVR < degree II 47.3 +/-8.4 vs controls 47.4 +/- 5, P= 0.97) and maximally (VO2max; athletes with LCVR < degree II 57.7 6.3 vs controls 57.1 +/- 5.1, P= 0.81). Neither levels of lactate nor of brain natriuretic peptide differed significantly. CONCLUSION: High level athletes presenting with aortic or mitral regurgitation < degree II in are not disadvantaged with regard to their cardiopulmonary capability.

Myocardial fibrosis is associated with biventricular dysfunction in patients with hypertrophic cardiomyopathy.

AIMS: To assess left (LV) and right ventricular (RV) function by two-dimensional (2D) speckle tracking echocardiography and its relation to myocardial fibrosis in hypertrophic cardiomyopathy (HCM). METHODS: We enrolled 50 HCM patients (30 male; 47.3 ± 9.9 years) in our study. Each patient received echocardiography with modern high-end scanners. For speckle tracking analysis of LV and RV function the dedicated software was used. The presence of myocardial fibrosis was detected by cardiac magnetic resonance imaging (MRI). RESULTS: For intraobserver variability of RV global longitudinal strain, we found a correlation of r = 0.89 (p < 0.001) with a minor bias of 4.9 ± 2.9%. On cardiac MRI 30 patients (60%) demonstrated late gadolinium-enhancement (LGE) of the LV. Of these patients only 7% showed LGE of the RV. HCM patients with myocardial fibrosis had less global longitudinal LV strain in comparison to patients without myocardial fibrosis (-12.8 ± 2.2 vs -21.1 ± 2.6, P < 0.001), thicker interventricular septums (23.7 ± 4.0 vs 19.2 ± 5.1, P < 0.001), larger left atria (34.9 ± 7.1 vs 23.9 ± 5.1, P < 0.001), and impaired diastolic function (E/A-ratio: 1.02 ± 0.22 vs 1.15 ± 0.18, P < 0.01). Comparable results were found for RV function. LV and RV strain correlated with r = 0.85 (p < 0.001). CONCLUSIONS: HCM is not only a disease of the LV. LGE in HCM is associated with both LV and RV dysfunction. Although RV LGE occurs only in a minority of patients with HCM and LV fibrosis, speckle tracking echocardiography is feasible for evaluating LV and RV dysfunction in these patients.

Diagnostic performance of handheld echocardiography for the assessment of basic cardiac morphology and function: a validation study in routine cardiac patients.

AIMS: To investigate the intra- and interrater variability of expert users in the interpretation of handheld echocardiographic studies (HAND). METHODS: We scanned 320 consecutive patients with both HAND and high-end (HIGH) scanners. Images were interpreted independently by two blinded level III echocardiographers. Readings from the HIGH scanner served as the gold standard. Segmental endocardial-border delineation was scored to describe image quality. Assessment of left ventricular (LV) dimensions and regional/global LV function, and grading of valve disease were compared. RESULTS: We obtained correlations of r > 0.8 (P < 0.01) for intrarater variability for both expert readers when they analyzed HAND and HIGH images in relation to image quality, wall-motion abnormalities, and LV measurements. For intrarater variability of LVEF assessment, the correlations were at least moderate (r > 0.6, P < 0.01). Interrater variability for HIGH images was r = 0.9 (P < 0.01) for all parameters. Interrater variability for HAND images was less favorable for all parameters, but was at least moderate (r > 0.6, P < 0.01). All cases of pericardial effusion were detected. The agreement for the detection and grading of mitral and aortic regurgitation was at least moderate (κ > 0.6, P < 0.01). Detection of tricuspid regurgitation was less favorable, but only cases of mild regurgitation were missed. All cases of aortic stenosis were detected by both echocardiographers. CONCLUSIONS: In relation to the basic assessment of cardiac morphology and function, the interpretation by experienced echocardiographers of images obtained using handheld echocardiographic devices showed a moderate to very good correlation with standard echocardiography.

Effective valve opening area in the detection of dysfunctional aortic valve prostheses: a differentiated statistical analysis of this parameter including the introduction of minimal expected normal values as borderline to dysfunctional stenotic prostheses.

BACKGROUND: Dysfunction of heart valve prostheses (VP) is a life-threatening complication and the diagnosis remains difficult. The motivation for this study was to improve the detection of dysfunctional VP by optimizing application of the prosthetic effective orifice area (VA). For this reason the minimal expected normal VA (VA(expected)) was introduced. METHODS: We investigated echocardiographically 1,369 normally functioning aortic valve prostheses (AVP). Mean VA, transprosthetic peak (PPG) and mean pressure gradients (MPG) were evaluated to gain reference values depending on prosthetic size and construction principle. Mean VA(expected) was calculated by applying a simple formula that was developed empirically using statistical analyses. The results were compared with those of 65 dysfunctional AVPs. RESULTS: VA(expected) can be applied as a threshold between normal and dysfunctional stenotic AVP and showed a correct estimation in 87% of all normally functioning and 100% of dysfunctional stenotic VPs. The sensitivity for all prosthetic sizes is 1.0, independently of the constructional principle of the VP. Specificity ranged between 0.8 and 1.0, dependent on VP size. The formula representing VA(expected) is simple and can be executed easily. CONCLUSION: As nearly independent of stroke volume and in consideration of VA(expected), VA seems to have become one of the preferable parameters for detecting pathological stenotic AVPs echocardiographically. The additional application of PPG/MPG and other parameters permits prostheses with relevant isolated regurgitation and patient-prosthesis-mismatch to be distinguished.

Consensus document regarding cardiovascular safety at sports arenas: position stand from the European Association of Cardiovascular Prevention and Rehabilitation (EACPR), section of Sports Cardiology.

Mass gathering events in sports arenas create challenges regarding the cardiovascular safety of both athletes and spectators. A comprehensive medical action plan, to ensure properly applied cardiopulmonary resuscitation, and wide availability and use of automated external defibrillators (AEDs), is essential to improving survival from sudden cardiac arrest at sporting events. This paper outlines minimum standards for cardiovascular care to assist in the planning of mass gathering sports events across Europe with the intention of local adaptation at individual sports arenas, to ensure the full implementation of the chain of survival.

In patients with hypertrophic cardiomyopathy myocardial fibrosis is associated with both left ventricular and left atrial dysfunction.

AIMS: The aim of this study was to assess LA function by two-dimensional speckle-tracking echocardiography and its relation with myocardial fibrosis in hypertrophic cardiomyopathy (HCM). METHODS: We enrolled 30 consecutive HCM-patients in our study (20 males; age: 49.7 +/- 10.4 years, NYHA-class: 1.9 +/- 0.7). Echocardiography was performed with assessment of global longitudinal LV strain (epsilon) and LA epsilon and strain-rate parameters (systolic, early diastolic, and late diastolic during atrial contraction). Each patient received delayed-enhancement magnetic resonance imaging (DE-MRI) to check for myocardial fibrosis. We divided the patients into two groups. Patients of group 1 had no fibrosis, group 2 demonstrated moderate or severe fibrosis in > or = 2 segments using a 17 segment-model of the LV. RESULTS: Moderate and severe fibrosis was observed in 20 patients (group 2: 66.7%). Global longitudinal LV epsilon (-13.0 +/- 2.4 vs -20.6 +/- 3.2%, P < 0.001) and peak LA epsilon (-0.2 +/- 3.9 vs 17.9 +/- 6.7%, P < 0.001) were reduced in group 2 in comparison with patients without myocardial fibrosis. In all patients peak LA epsilon correlated with global longitudinal LV epsilon (r = -0.78, P < 0.001). Patients with considerable myocardial fibrosis (group 2) had a higher indexed left atrial volume (35.7 +/- 12.8 ml/m2 vs 24.1 +/- 8.6 ml/m2, P = 0.016). New York Heart Association class (NYHA) was higher in patients with severe myocardial fibrosis (2.2 +/- 0.7 vs 1.3 +/- 0.5) and correlated with peak LA (r = -0.5, P = 0.008) and global LV epsilon (r = 0.5, P = 0.005). CONCLUSIONS: Occurrence of myocardial fibrosis in hypertrophic cardiomyopathy is associated with left atrial and ventricular dysfunction as well as with the severity of heart failure symptoms.

The occurrence of atrial fibrillation in former top-level handball players above the age of 50.

OBJECTIVE: Cardiac adaptation to sports activity in endurance athletes is considerably different from that in power athletes. The effects of a high-level team sport like handball, one of the most popular sports in the world, performed at a younger age, on cardiac rhythm in individuals above the age of 50 have not been investigated to date. METHODS: Thirty-three former top-level handball players from the first German league (6 former world champions and numerous Olympians) (57.5 +/- 5.5 y) joined our screening programme for former athletes and underwent electrocardiography, echocardiography and spiroergometry. Data were compared to 24 sedentary healthy controls. RESULTS: Ten of the 33 athletes suffered from atrial fibrillation (AF). Left ventricular diameter was 53.68 +/- 4.88 mm in the athletes group and 50.58 +/- 4.12 mm in the healthy controls. Analysing the subgroups of handball players ('AF group' and 'non-AF group'), spiroergometry showed oxygen consumption at the anaerobic threshold of 27.54 +/- 6.77 ml/kg/min in the AF group and 31.24 +/- 10.33 ml/kg/min in the non-AF group (P = 0.228). Absolute left atrial diameter was 44.34 +/- 4.41 mm in the AF group (non-AF group 38.94 +/- 3.77 mm, P < 0.001) (healthy controls 37.54 +/- 4.34 mm, compared with all athletes P = 0.015). In all individuals left ventricular wall thickness was within normal limits. However, myocardial walls were thicker in the AF group (11.28 +/- 1.83 mm) than in the non-AF group (9.44 +/- 1.26 mm, P = 0.002). Athletes in the AF group (187.6 +/- 6.42 cm) were significantly taller than in the non-AF group (180.91 +/- 7.31 cm, P = 0.018). CONCLUSION: Not only endurance training, but also sports activity with a relevant static component, like team handball, might predispose for AF above the age of 50. LA size, height and myocardial wall thickness seem to affect the risk of developing AF. More data in non-endurance sports are mandatory to confirm this hypothesis.

Real-time three-dimensional transoesophageal echocardiography during percutaneous transcatheter occlusion of mitral periprosthetic paravalvular leak.

We present the case of an 86-year-old female patient with a history of mitral valve replacement due to relevant stenosis. After surgery, an increasing periprosthetic valvular leak (PVL) became obvious causing regurgitation and an increasing haemolysis. Conventional two-dimensional transoesophageal echocardiography (2D TEE) showed a defect of 15 mm length located from the lateral to the posterior circumference subdivided by two surgical sutures into three parts. The patient refused additional surgical therapy. Hence, we suggested a percutaneous transcatheter occlusion of the leakage with a 12 × 5 mm Amplatzer(®) Vascular Plug III device (AVP) (AGA Medical Corporation, Plymouth, MA, USA). The placement of the device was supported indispensably by real-time three-dimensional TEE. The device occluded the leakage nearly completely and downgraded the regurgitation from moderate to neglectable. Also haemolytic parameters improved significantly. V-wave decreased promptly from 70 to 35 mmHg after placing AVP. Percutaneous closure of PVL by AVP, a self-expandable nitinol device approved for peripheral vessel occlusion, is described in limited cases with more or less successful results. It is graded as a technically demanding procedure reserved to poor surgical candidates. The main challenge is finding and intubating the leakage and the correct placement of the device. Three-dimensional TEE seems to be superior to conventional 2D TEE as it allows an easier guidance of the device into the defect. Hence, it is strongly recommended for this intracardiac intervention.

Athletes with valvular heart disease and competitive sports: a position statement of the Sport Cardiology Section of the European Association of Preventive Cardiology.

This article provides an overview of the recommendations from the Sports Cardiology section of the European Association of Preventive Cardiology on sports participation in individuals with valvular heart disease (VHD). The aim of these recommendations is to encourage regular physical activity including sports participation, with reasonable precaution to ensure a high level of safety for all affected individuals. Valvular heart disease is usually an age-related degenerative process, predominantly affecting individuals in their fifth decade and onwards. However, there is an increasing group of younger individuals with valvular defects. The diagnosis of cardiac disorders during routine cardiac examination often raises questions about on-going participation in competitive sport with a high dynamic or static component and the level of permissible physical effort during recreational exercise. Although the natural history of several valvular diseases has been reported in the general population, little is known about the potential influence of chronic intensive physical activity on valve function, left ventricular remodelling pulmonary artery pressure, and risk of arrhythmia. Due to the sparsity of data on the effects of exercise on VHD, the present document is largely based on clinical experience and expert opinion.

Systolic and early diastolic left ventricular velocities assessed by tissue Doppler imaging in 100 top-level handball players.

BACKGROUND AND OBJECTIVE: Echocardiographic tissue Doppler imaging (TDI) has been proposed for the differentiation of physiologic left ventricular hypertrophy and pathologic left ventricular hypertrophy in athletes. In addition, cutoff values for systolic (S'<9 cm/s) and early diastolic (E'<9 cm/s) myocardial velocities had been defined. The aim of our study was the analysis of the morphologic cardiac changes by standard echocardiography, and the myocardial velocities S' and E' by TDI in top-level handball players with respect to the predefined cutoff values. PATIENTS AND METHODS: Pulsed-wave TDI of the systolic and early diastolic velocities was performed at the lateral and septal mitral annulus (MA) in the four-chamber view in 100 athletes (100 Caucasian men; professional handball players of the first German handball league and the German national team; mean age 25.8+/-4.8 years). RESULTS: Global and regional left ventricular systolic function was normal in all athletes. They showed an eccentric hypertrophy of the left ventricle (LV), which was characterized by an increased mass of the LV (287.3+/-58.4 g), and an increased end diastolic diameter of the LV (LVEDD: 58+/-5.9 mm), but no echomorphologic signs of pathologic hypertrophy or hypertrophic cardiomyopathy. TDI showed a systolic velocity S' of the MA of 9.3+/-1.5 cm/s at the septal and 10.5+/-2.1 at the lateral MA. Ten of the 100 athletes showed a S'<9 cm/s at both sides of the MA. TDI showed an early diastolic velocity E' of the MA of 13.2+/-2.8 cm/s at the septal and of 16.6+/-3.4 cm/s at the lateral MA. None of the 100 athletes showed reduced systolic or early diastolic velocities below the proposed cutoff values (S' and E'<9 cm/s) at any sides of the MA. CONCLUSION: Our study provides further insights into systolic and diastolic function as assessed by TDI in top-level handball players. Owing to the large cohort of individuals, our findings might be helpful as reference values for the echocardiographic assessment of handball players, who are performing a moderate static and high dynamic sport.

Transradial percutaneous coronary interventions: technique, materials & procedure in the light of anatomical and technical considerations.

Transradial access is associated with enhanced patients' comfort, significant lower complication rates in diagnostic coronary angiography and better immediate and long-term outcomes after transradial percutaneous coronary interventions. Access failure has been reported to occur in less than 3-7% of cases due to anatomical circumstances (e.g., anomalous radial branching patterns, tortuosity e.g. radial loops, and small radial artery diameters). Radial coronary angiography and angioplasty entail a secondary learning curve of at least 150 cases in order to become familiar and comfortable with this technique. In contrast to previous established techniques (e.g. Sones-arteriotomy), the patient should be positioned in a comfortable supine position with his right arm next to his hip and the interventionist next to the right side of the patient. 19 gauge needles and 0.018 inch wires enhance the chance of successful cannulation the radial artery. A spasmolytic cocktail (3 mg Dinitrate, 3 mg verapamil, at least 3.000 U Heparine) should always be given intraarterially. Longer sheaths (> 13 cm) are not necessary. Essential for easy passage of the vertebralian artery and the common brachio-cephalic trunc (as the most dangerous part of the procedure) in order to reach the ascending aorta, the patient should be asked for a deep inspiration and/or dorsoflexion of his head An Amplatz-II catheter can be used for LCA, RCA and in some cases for LV-angiogram. The sheath should always be removed immediately and hemostasis achieved by radial compression (e.g. clamp). There is a close relationship between access failure respective radial spasm or occlusions and anatomical circumstances (i.e., hypoplastic radial artery, radioulnar loop, or small radial diameters: radial diameter-to-catheter ration < 1.0; assessment by Duplex). Although the radial access can be used in the majority of patients, the use is limited in patients with very small radial diameters and/or with complex lesions (e.g kissing balloon, etc).
