Multimodality imaging for myocardial injury in acute myocardial infarction and the assessment of valvular heart disease

In this PhD thesis we have studied left ventricular systolic deformation with novel cardiovascular magnetic resonance (CMR) algorithm called feature-tracking in patients with acute myocardial infarction (MI). We have shown that left ventricular strain with feature-tracking CMR offers an incremental value above conventional imaging parameters in the assessment of prognosis of patients with acute MI. In addition, left ventricular strain analysis confirmed a clear clinical benefit of early intravenous betablocker treatment in patients with acute MI. Moreover, we have explored the feasibility of novel automated 3D echocardiographic algorithm in the assessment of the aortic root anatomy in patients with severe aortic stenosis prior to transcatheter aortic valve replacement (TAVR). The 3D echocardiographic algorithm performed excellent against the gold standard multidetector row computed tomography to determine the aortic annulus size and to choose the correct TAVR prosthesis size; however, the accuracy was a bit lower in patients with severely calcified aortic valves. In addition, we have explored the advantages and limitations of different cardiac imaging techniques in the assessment of patients with TAVR, the role of multimodality imaging in patients with combined valvular heart disease and heart failure, and the role of myocardial fibrosis assessment with CMR in valvular heart disease.Dutch Heart FoundationLUMC / Geneeskund

EACVI survey on hypertrophic cardiomyopathy

Publisher Copyright: Published on behalf of the European Society of Cardiology. All rights reserved. © The Author(s) 2021. For permissions, please email: [email protected]: The European Association of Cardiovascular Imaging (EACVI) Scientific Initiatives Committee performed a global survey to evaluate current practice for the assessment and management of patients with hypertrophic cardiomyopathy (HCM). METHODS AND RESULTS: A total of 213 centres from 38 different countries (87% European) responded to the survey. One hundred twenty-one (57%) centres followed HCM patients in a general cardiology outpatient clinic and 85 (40%) centres in a specialized HCM/cardiomyopathy clinic. While echocardiography was the primary imaging modality, cardiovascular magnetic resonance (CMR) has become an important complementary tool. Cardiac anatomy, left ventricular (LV) systolic, and diastolic function were assessed according to current European guidelines and recommendations. To evaluate LV obstruction, 49% of the centres performed bedside provocation manoeuvres in every patient and 55% of the centres used exercise stress echocardiography. The majority of centres used the 5-year risk assessment of sudden cardiac death (SCD) calculated with the HCM Risk-SCD score. However, 34% of the centres also used extensive non-infarct late gadolinium enhancement on CMR and 27% the presence of LV apical aneurysm to help select patients for primary prevention implantable cardioverter-defibrillator therapy. Ninety-nine percent of the responding centres performed regular imaging follow-up of HCM patients. CONCLUSION: Most centres followed European guidelines and recommendations for the diagnosis and management of patients with HCM. The importance of bedside provocation manoeuvres and exercise stress echocardiography to diagnose LV outflow obstruction requires emphasis. Additional risk markers for SCD are used in many centres and might indicate the need for an update of current European recommendations.publishersversionpublishe

European Association of Cardiovascular Imaging survey on the evaluation of mitral regurgitation

AIMS To evaluate the diagnosis and imaging of patients with mitral regurgitation (MR) and the management in routine clinical practice across Europe, the European Association of Cardiovascular Imaging Scientific Initiatives Committee performed a survey across European centres. In particular, the routine use of echocardiography, advanced imaging modalities, heart valve clinics, and heart valve teams was explored. METHODS AND RESULTS A total of 61 responders, mainly from tertiary centres or university hospitals, from 26 different countries responded to the survey, which consisted of 22 questions. For most questions related to echocardiography and advanced imaging, the answers were relatively homogeneous and demonstrated good adherence to current recommendations. In particular, the centres used a multi-parametric echocardiographic approach and selected the effective regurgitant orifice and vena contracta width as their preferred assessments. 2D measurements are still the most widely used parameters to assess left ventricular structure; however, the majority use 3D trans-oesophageal echocardiography (TOE) to evaluate valve morphology in severe MR. The majority of centres reported the onsite availability and clinical use of ergometric stress echocardiography, cardiac computed tomography (CCT), and cardiac magnetic resonance (CMR) imaging. Heart valve clinics and heart valve teams were also widely prevalent. CONCLUSION Consistent with current guidelines, echocardiography (transthoracic echocardiography and TOE) remains the first-line and central imaging modality for the assessment of MR although the complementary use of 3D TOE, CCT, and CMR appears to be growing. Heart valve clinics and heart valve teams are now widely prevalent

EACVI survey on investigations and imaging modalities in chronic coronary syndromes

AIMS The European Association of Cardiovascular Imaging (EACVI) Scientific Initiatives Committee performed a global survey to evaluate current practice for the assessment and management of patients with suspected and confirmed chronic coronary syndromes. METHODS AND RESULTS One-hundred and ten imaging centres from 37 countries across the world responded to the survey. Most non-invasive investigations for coronary artery disease were widely available, except cardiovascular magnetic resonance (available 40% centres). Coronary computed tomography angiography (CCTA) and nuclear scans were reported by a multi-disciplinary team in only a quarter of centres. In the initial assessment of patients presenting with chest pain, only 32% of respondents indicated that they rely on pre-test probability for selecting the optimal imaging test while 31% proceed directly to CCTA. In patients with established coronary artery disease and recurrent chest pain, respondents opted for stress echocardiography (27%) and nuclear stress perfusion scans (26%). In asymptomatic patients with coronary artery disease and an obstructive (>70%) right coronary artery stenosis, 58% of respondents were happy to pursue medical therapy without further testing or intervention. This proportion fell to 29% with left anterior descending artery stenosis and 1% with left main stem obstruction. In asymptomatic patients with evidence of moderate-to-severe myocardial ischaemia (15%), only 18% of respondents would continue medical therapy without further investigation. CONCLUSION Despite guidelines recommendations pre-test probability is used to assess patients with suspected coronary artery in a minority of centres, one-third of centres moving directly to CCTA. Clinicians remain reticent to pursue a strategy of optimal medical therapy without further investigation or intervention in patients with controlled symptoms but obstructive coronary artery stenoses or myocardial ischaemia

Nuclear medicine practice for the assessment of cardiac sarcoidosis and amyloidosis:A survey endorsed by the EANM and EACVI

INTRODUCTION : Cardiac amyloidosis (CA) is an infiltrative and restrictive cardiomyopathy that might rapidly lead to heart failure if left untreated. The prognosis is variable and depends on the type of cardiac amyloidosis, but the end stages are associated with poor outcomes and the disease is often associated with important morbidity and reduced quality of life.
