ANMCO position paper: 2022 focused update of appropriate use criteria for multimodality imaging: aortic valve disease

This document addresses the evaluation of the Appropriate Use Criteria (AUC) of multimodality imaging in the diagnosis and management of aortic valve disease. The goal of this AUC document is to provide a comprehensive resource for multimodality imaging in the context of aortic valve disease, encompassing multiple imaging modalities. Clinical scenarios are developed in a simple way to illustrate patient presentations encountered in everyday practice.

[Follow-up after surgical treatment of type A acute aortic dissection: current evidence and controversies]

Type A acute aortic dissection (TA-AAD) is a catastrophic condition for which emergency surgery is the mainstay of therapy. Surgical treatment of TA-AAD is centered on excision of the proximal intimal tear, replacement of the ascending aorta and re-establishment of a dominant flow in the distal true lumen. In patients who survive surgery, a dissected distal and/or proximal aorta remains, posing a risk of subsequent aneurysmal degeneration, rupture and malperfusion, and secondary extensive interventions are often required. However, knowledge regarding the risk factors of progression of residual aortic dissection is limited, and no well-defined recommendations for clinical and imaging follow-up have been generated thus far. The aim of this paper is to review and discuss on the current evidence and controversies on the long-term management of patients operated on for TA-AAD.

[Cardiovascular prevention in the elderly: limitations and opportunities]

The world's population is ageing; however, the prolonged life expectancy is barely associated with an increase of healthy aging, and an important part of this demographic shift is a rising susceptibility to development and progressive accumulation of multiple chronic illness, challenging healthcare systems. Aging, therefore, represents the major risk factor for multimorbidity, a milestone for progressive loss of resilience and age-related multisystem homeostatic dysregulation. Cardiovascular risk factors, time and comorbidities play a vicious role in the development of heart disease. Among the other comorbidities, age itself is one of the most important risk factors for the development of cardiovascular disease and the prevalence and incidence of cardiovascular disease in the elderly are significantly increased. Elderly subjects, particularly when frail and with comorbidities, however, are scarcely represented in primary and secondary prevention trial aimed to treat hypercholesterolemia, diabetes mellitus and arterial hypertension. In particular, concerns exist about whether treatment should more or less intensive according to tolerability and risk of interactions; as well as there is uncertainty about therapeutic targets at different ages.This article reviews the relationship between ageing and cardiovascular disease, focusing on several issues regarding cardiovascular prevention in the elderly.

[ANMCO/SICI-GISE/SIC/SIECVI/SIRM Consensus document: Appropriateness of multimodality imaging in cardiovascular disease]

The complexity of cardiovascular diseases has led to an extensive use of technological instruments and the development of multimodality imaging. This extensive use of different cardiovascular imaging tests in the same patient has increased costs and waiting times.The concept of appropriateness has changed over time. Appropriateness criteria address the need for specific cardiovascular imaging tests in well-defined clinical scenarios, and define the kind of cardiovascular imaging that is appropriated for each clinical scenario in different stages of the disease. The concept of appropriateness criteria has replaced the old idea of appropriate use criteria and reflects the increasing effort of the international Scientific Societies to create and review in a critical way the management of diagnostic tests used by clinicians.The aim of this Italian consensus document is to address the use of multimodality imaging in the diagnosis and management of the major cardiovascular clinical scenarios, taking into consideration not only the international guidelines and scientific documents already published, but also the reality of Italian laws as well as the various professional profiles involved in patient management and availability of technological diagnostic instruments.

[Role of multimodality imaging in the clinical evaluation of hypertrophic cardiomyopathy]

Sarcomeric hypertrophic cardiomyopathy is the most common cardiovascular genetic disease. Clinical evaluation and comprehensive echocardiography are crucial for the diagnosis and early evaluation of the hypertrophic phenotype, but multimodality imaging approach is often required to better define diagnosis and differential diagnosis from phenocopies. This review aims to assess the role of multimodality imaging and, in particular, advanced echocardiography and cardiac magnetic resonance in relation to differential diagnosis and preclinical diagnosis, identification of different phenotypes, and assessment of disease progression and risk of sudden cardiac death. A multimodality imaging approach is also crucial for the selection of patients amenable to surgical or percutaneous septal myectomy and for guiding both procedures.

[ANMCO/GISE/SICCH Inter-Society Consensus Document: Antithrombotic therapy after surgery or structural interventional procedures for valvular heart diseases: how to treat postoperative complications]

Continuous improvement of technologies, devices and drugs needs a renewal and update of current recommendations and guidelines on antithrombotic strategies, especially in those fields where literature lacks of established scientific evidences. Accordingly, the aim of this consensus statement is to provide support for antithrombotic therapy based on current guidelines and the most recent scientific evidences.After an overview on the currently available devices, the appropriate therapy according to type of procedure and implanted device is discussed. The occurrence of postoperative thromboembolic and/or hemorrhagic complications is analyzed, along with the appropriate diagnostic tools and therapeutic approach. A section is dedicated to counseling to pregnancy in women with heart valve prosthesis. Finally, the role of novel oral anticoagulants is discussed, and indications are provided for the management of patients undergoing surgery or interventional procedures on oral anticoagulation therapy.

ANMCO/SIC/SICI-GISE/SICCH Executive Summary of Consensus Document on Risk Stratification in elderly patients with aortic stenosis before surgery or transcatheter aortic valve replacement

Aortic stenosis is one of the most frequent valvular diseases in developed countries, and its impact on public health resources and assistance is increasing. A substantial proportion of elderly people with severe aortic stenosis is not eligible to surgery because of the advanced age, frailty, and multiple co-morbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy. However, a significant percentage of patients die or show no improvement in quality of life (QOL) in the follow-up. In the decision-making process, it is important to determine: (i) whether and how much frailty of the patient influences the risk of procedures; (ii) how the QOL and the individual patient's survival are influenced by aortic valve disease or from other associated conditions; and (iii) whether a geriatric specialist intervention to evaluate and correct frailty or other diseases with their potential or already manifest disabilities can improve the outcome of surgery or TAVI. Consequently, in addition to risk stratification with conventional tools, a number of factors including multi-morbidity, disability, frailty, and cognitive function should be considered, in order to assess the expected benefit of both surgery and TAVI. The pre-operative optimization through a multidisciplinary approach with a Heart Team can counteract the multiple damage (cardiac, neurological, muscular, respiratory, and kidney) that can potentially aggravate the reduced physiological reserves characteristic of frailty. The systematic application in clinical practice of multidimensional assessment instruments of frailty and cognitive function in the screening and the adoption of specific care pathways should facilitate this task.

[ANMCO/SIC/SICI-GISE/SICCH Consensus document: Risk stratification in elderly patients undergoing cardiac surgery and transcatheter aortic valve implantation]

Aortic stenosis is one the most frequent valvular diseases in developed countries, and its impact on public healthcare resources and assistance is increasing. A substantial proportion of elderly patients with severe aortic stenosis is frequently not eligible for surgery because of advanced age, frailty and multiple comorbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy. However, a significant proportion of patients die or do not achieve an improvement of quality of life in the short to medium-term follow-up. It is important to determine: 1) whether and how much patient frailty influences the procedural risk; 2) whether quality of life and the individual patient survival are influenced by aortic valve disease alone or by other associated factors; 3) whether a geriatric specialist intervention to evaluate and correct other diseases with their potential or already evident disabilities can improve the results of TAVI, in particular patient quality of life. Consequently, in addition to risk stratification with conventional tools, a number of factors including multimorbidity, disability, frailty and cognitive function should be considered in order to assess the expected benefit of TAVI. Preoperative optimization through a multidisciplinary approach with a Heart Team can counteract the multiple damage (cardiac, neurological, muscular, respiratory, renal) that can potentially worsen the reduced physiological reserves characteristic of frailty. The systematic implementation into clinical practice of multidimensional assessment instruments of frailty and cognitive function for screening and exercise, and the adoption of specific care pathways should facilitate this task.

Transesophageal Echocardiography and Radiation-induced Damages

The long-term sequelae of mantle therapy include, especially lung and cardiac disease but also involve the vessels and the organs in the neck and thorax (such as thyroid, aorta, and esophagus). We presented the case of 66-year-old female admitted for congestive heart failure in radiation-induced heart disease. The patient had undergone to massive radiotherapy 42 years ago for Hodgkin's disease (type 1A). Transesophageal echocardiography was performed unsuccessfully with difficulty because of the rigidity and impedance of esophageal walls. Our case is an extraordinary report of radiotherapy's latency effect as a result of dramatic changes in the structure of mediastinum, in particular in the esophagus, causing unavailability of a transesophageal echocardiogram.

Posterior wall as atypical localization of left atrial myxoma : Diagnosis and management

Atrial myxomas are the most common benign cardiac neoplasms. Although the majority occur in the left atrium (LA) and are attached to the interatrial septum (75-80 % of cases), they can arise from any part of the LA and the cardiac chambers. We report the case of a 65-year-old woman who presented with features of worsening dyspnea and persistent headache. During transthoracic echocardiography, a suspected cardiac myxoma was found arising from the posterior wall of the LA.

Combined venoarterial extracorporeal membrane oxygenation and transcatheter aortic valve implantation for the treatment of acute aortic prosthesis dysfunction in a high-risk patient

We describe the case of a patient with acute bioprosthesis dysfunction in cardiogenic shock, in whom hemodynamic support was provided by venoarterial extracorporeal membrane oxygenation, and successfully treated by transcatheter aortic valve implantation.

The Strange Case of the Infarcted Myxoma

In the setting of an acute coronary syndrome, the differential diagnosis between a thrombus and a myxoma may be cumbersome. We describe the case of a patient presenting with an acute coronary syndrome associated with an aneurysmatic apical left ventricular myxoma.

St. Jude Trifecta versus Carpentier-Edwards Perimount Magna valves for the treatment of aortic stenosis: comparison of early Doppler-echocardiography and hemodynamic performance

OBJECTIVE

Aim of this study was to compare the hemodynamic profiles of 2 aortic valve bioprostheses: the Carpentier Edwards Perimount Magna (CEPM) valve and the Trifecta valve.

METHODS

100 patients who underwent AVR for severe symptomatic AS between September 2011 and October 2012 were analyzed by means of standard trans-thoracic Doppler-echocardiography.

RESULTS

Mean and peak gradients were significantly lower for the 21 mm Trifecta vs CEPM (11 +/- 4 vs 15 +/- 4 mmHg, and 20 +/- 6 vs 26 +/- 7 mmHg, respectively; all p < 0.05) and the 23 mm Trifecta vs CEPM (8 +/- 2 vs 14 +/- 4 mmHg, and 17 +/- 6 vs 25 +/- 9 mmHg; all p < 0.05). Effective orifice area tended to be slightly higher for the Trifecta valve.

CONCLUSION

The new bioprosthetic valve Trifecta has an excellent hemodynamic profile, and lower trans-prosthesic gradients when compared to CEPM valve.

The importance of being "three-dimensional": how to save a mitral valve. Case report

In a 72-year-old male patient an acute coronary syndrome (ACS) was complicated by left ventricular aneurysm and severe mitral regurgitation. Two-dimensional echocardiography failed in detecting mechanism of mitral regurgitation. Transthoracic three dimensional echocardiography allowed us to obtain a better visualization of the relationship between papillary muscles, ventricular walls and mitral leaflets and dynamic systolic displacement of the posterior papillary muscle associated with restriction of both leaflets with greater apical tethering of anterior leaflet (A3-A2 scallops). Echocardiography performed after cardiac surgery revealed that ventricular reshaping after posterior papillary muscle realignment allowed the mitral regurgitation resolution.

Real-Time 3D echocardiography in a young adult with idiopathic dilatation of the pulmonary artery: a case report

Idiopathic dilatation of the pulmonary artery (IDPA) is an uncommon anomaly occurring in 0.6% of patients with congenital heart disease. IDPA is characterized by the enlargement of the main pulmonary artery with or without dilatation of the right and left pulmonary arteries. We describe 2D and Real-Time 3D Echocardiography findings in a young adult with IDPA. To the best of our knowledge this is the first case reporting all echocardiographic findings diagnostic for IDPA.

Congenitally corrected transposition of the great arteries with severely stenotic bicuspid aortic valve in an adult: a case report

Congenitally corrected transposition of the great arteries (CCTGA) is a rare disease accounting for 0.5-1.4% of patients with congenital heart disease. In this congenital cardiopathy, the left atrium is connected to the right ventricle, from which the aorta stems. We present a case of an adult with CCTGA associated with aortic stenosis and bicuspid aortic valve-an association not yet described to our knowledge. 

An isolated anterior mitral leaflet cleft: a case report

Introduction

The anterior mitral leaflet cleft is an unusual congenital lesion most often encountered in association with other congenital heart defects. The isolated anterior leaflet cleft is quite a rare anomaly and is usually cause of mitral valve regurgitation. The importance of the lesion is that it is often correctable. When feasible, cleft suture and, eventually, annuloplasty are preferable to valve replacement. Echocardiography is the first choice technique in the evaluation of mitral valve disease, providing useful information about valve anatomy and hemodynamic parameters.

Case presentation

We present a case of an isolated anterior mitral leaflet cleft producing moderate-severe mitral regurgitation correctly identified by echocardiography and successfully surgically corrected.

Conclusion

Isolated cleft is a rare aberration, that has to be known in order to be diagnosed. Transthoracic and transesophageal echocardiography is the most useful non invasive technique for cleft diagnosis and to indicate the right surgical correction.

Preoperative scallop-by-scallop assessment of mitral prolapse using 2D-transthoracic echocardiography

Background

This study was conducted to assess the accuracy of harmonic imaging 2D-transthoracic echocardiography (2D-TTE) segmental analysis compared to surgical findings, in degenerative mitral regurgitation (MR).

Methods

Seventy-seven consecutive patients with severe degenerative MR were prospectively enrolled. Preoperative 2D-TTE with precise localization of prolapsing or flailing scallops/segments was performed. All patients underwent mitral valve surgical repair. Surgical reports (SR), including valve description, were used as references for comparisons. A postoperative control 2D-TTE was performed.

Results

Out of 462 scallops/segments studied, surgical inspection identified 102 prolapses or flails (22%), 92 of which had previously been detected by 2D-TTE (90.2% sensitivity, 100% specificity). Agreement between preoperative 2D-TTE segmental analysis and SR was 97.8% (k = 0.93; p < 0.0001). Sixty-nine out of 77 2D-TTE reports were completely concordant with SR (89.6% diagnostic accuracy). None of the 8 non-concordant 2D-TTE reports were in complete disagreement with SR. P2 scallop was always involved in posterior leaflet prolapse or flail and was described correctly by 2D-TTE in 68 out of 69 patients (98,7% agreement, k = 0,93; 98.5% sensitivity). The anterior leaflet was involved in 14 patients (18%); A2 segment was involved in all of those cases and was correctly detected by 2D-TTE in 13 (98,7% agreement, k = 0,95; 92,8% sensitivity). Antero-lateral and postero-medial para-commissural prolapse or flail had a lower prevalence (14% and 10% respectively), with 2D-TTE sensitivity respectively of 64% and 50%.

Conclusions

2D-TTE, performed by an experienced echo-lab, has very good diagnostic accuracy in localizing the scallops/segments involved in degenerative MR, particularly for the middle ones (P2-A2), which represent almost the totality of prolapses. More invasive, time consuming and expensive exams should be reserved to selected cases.

Biphasic transoesophageal vs. transthoracic electrical cardioversion of persistent atrial fibrillation

OBJECTIVE

To compare the efficacy and safety of transoesophageal (TOC) vs. transthoracic (TTC) electrical cardioversion, both with biphasic shocks, for sinus rhythm (SR) restoration in patients with persistent atrial fibrillation (AF).

METHODS

We randomised 210 patients (151 male, 59 female, mean age 66 +/- 9 years) with persistent AF into two groups: group 1 (n = 104) undergoing TOC with a step-up protocol of 30, 50, 70 and 100 J, and group 2 (n = 106) undergoing TTC with a step-up protocol of 70, 100, 120 and 150 J.

RESULTS

The two groups were homogeneous as for clinical and instrumental characteristics, except for left ventricular ejection fraction (50.5 +/- 10% in group 1 vs. 53 +/- 8% in group 2, P < 0.05) and thoracic impedance (63 +/- 8 Omega in group 1 vs. 66 +/- 6 Omega in group 2, P < 0.005). SR was restored in 98 (94%) group 1 patients vs. 99 (93%) group 2 patients (P = NS). First shock was effective in 48 (46%) group 1 patients vs. 54 (51%) group 2 patients (P = NS). Mean delivered energy was 50.4 +/- 23.6 and 95.1 +/- 29.6 J; mean effective energy was 47.3 +/- 20.7 and 91.2 +/- 26.6 J in group 1 and group 2, respectively. Cross-over to the highest energy level was never effective. TOC tolerability was optimal (mean discomfort score 1.2 on a 1-4 grading scale). Markers of myocardial necrosis did not increase and no procedure-related complications occurred. On logistic regression analysis, the most predictive variables of unsuccessful cardioversion were AF duration (P = 0.0001) and low left atrial appendage emptying velocity (P = 0.02).

CONCLUSIONS

Both TOC and TTC with biphasic shocks are effective and safe for SR restoration in patients with persistent AF; however, the considerably lower levels of delivered and effective energies for SR restoration allow TOC to be performed during mild sedation with optimal tolerability, thus avoiding general anaesthesia.

[Primary lymphoma of the right atrium: a case report]

Primary cardiac tumor is an extremely rare disease and is associated with a high mortality. The cases described in the literature are recently increased thanks to the employment of the new diagnostic methodologies (computed tomography, nuclear magnetic resonance, transesophageal echocardiography). Particularly the primitive lymphoma, non-HIV correlated, is very rare (< 1.5% of all cardiac tumors), but it is treatable when appropriately diagnosed. We report a case of 52-year-old patient who presented with an infiltrative mass in the right atrium. The examination of the tissue obtained by transvenous intracardiac biopsy with transesophageal echocardiography guidance revealed high grade non-Hodgkin's lymphoma of B-cell lineage. The patient achieved complete tumor remission after treatment with standard chemotherapy. This case demonstrates that early diagnosis might contribute to a better prognosis for patients with malignant lymphoma of the heart.
