Aortopathy and aortic valve surgery in patients with bicuspid aortic valve with and without raphe.

AIM: To evaluate the association between raphe in bicuspid aortic valve (BAV) patients and valve dysfunction, aortopathy and aortic valve surgery in the REBECCA registry [REgistro della valvola aortica Bicuspide della Società Italiana di ECocardiografia e CArdiovascular Imaging (SIECVI)]. METHODS: Prevalence of aortic valve dysfunction and aortopathy was investigated in BAV patients with and without raphe. Aortic valve dysfunction (regurgitation or stenosis) was categorized as mild, moderate and severe. Aortopathy was defined as annulus ≥14 mm/m2; root ≥20 mm/m2; sinotubular junction ≥16 mm/m2; ascending aorta ≥17 mm/m2, and classified in Type A, isolated ascending aorta dilatation; Type B, aortic root and ascending aorta dilatation; and Type C, isolated aortic root dilatation. RESULTS: Overall, 695 patients with BAV were enrolled; 520 (74.8%) with raphe and 175 (25.2%) without raphe. BAV patients with raphe presented more frequently with moderate or severe aortic stenosis than BAV patients without raphe (183 [35.2%] vs 34 [19.4%], p < 0.001). A higher prevalence of aortopathy, particularly Type B, was observed in patients with vs without raphe. At multivariable analysis, raphe was a predictor of aortic valve surgery at three-year follow-up (odds ratio 2.19, 95% confidence interval 1.08-4.44, p < 0.001). CONCLUSIONS: Patients with BAV and raphe have a higher prevalence of significant aortic stenosis, aortopathy, especially Type B, and a higher risk of undergoing aortic valve surgery at three-year follow-up.

Exploring the Relationship between Epicardial Fat Thickness and Coronary Revascularization: Implications for Cardiovascular Health.

BACKGROUND: this study aimed to assess the complex relationship between EAT thickness, as measured with echocardiography, and the severity of coronary artery disease (CAD). We investigated whether individuals with higher EAT thickness underwent coronary revascularization. Subsequently, we conducted a three-year follow-up to explore any potential modifications in EAT depots post-angioplasty. METHODS: we conducted a prospective and retrospective cross-sectional observational study involving 150 patients consecutively referred for acute coronary syndrome, including ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), and unstable angina. Upon admission (T0), all patients underwent coronary angiography to assess the number of pathologic coronary vessels. Percutaneous transluminal coronary angioplasty (PTCA) was performed based on angiogram results if indicated. The sample was categorized into two groups: non-revascularized (no-PTCA) and revascularized (PTCA). Transthoracic echocardiograms to measure epicardial fat thickness were conducted at admission (T0) and after a 3-year follow-up (T1). RESULTS AND CONCLUSIONS: findings revealed a positive correlation between EAT thickness and the severity of coronary artery disease (CAD), with patients undergoing PTCA showing decreased EAT thickness after three years. Echocardiography demonstrated reliability in assessing EAT, offering potential for risk stratification. The study introduces a cut-off value of 0.65 cm as a diagnostic tool for cardiovascular risk. Incorporating EAT measurements into clinical practice may lead to more precise risk stratification and tailored treatment strategies, ultimately reducing the burden of cardiovascular disease.

Cardiac Tumors.

Cardiac tumors (CTs) are extremely rare, with an incidence of approximately 0.02% in autopsy series. Primary tumors of the heart are far less common than metastatic tumors. CTs usually present with any possible clinical combination of heart failure, arrhythmias, or embolism. Echocardiography remains the first diagnostic approach when suspecting a CT which, on the other side, frequently appears unexpectedly during an echocardiographic examination. Yet, cardiac tomography and especially magnetic resonance imaging may offer several adjunctive opportunities in the diagnosis of CTs. Early and exact diagnosis is crucial for the following therapy and outcome of CTs.

Mitral annular calcification: Can CMR be useful in identifying caseous necrosis?

Mitral annular calcification (MAC) can resemble an intracardiac mass and it is defined as a chronic degeneration of the mitral annulus. Often reported is caseous mitral annulus calcification (CMAC), a periannular, extensive calcification resembling a tumor. We report the case of a 68-year-old woman who had been hospitalized for palpitations and dyspnea. The transthoracic and transesophageal echocardiography revealed a non-homogeneous, slightly mobile, round mass, attached to the ventricular side of posterior mitral leaflet, with central echo-lucent area and without acoustic shadowing. Therefore, a cardiac magnetic resonance (CMR) was performed; delayed enhancement sequences showed a non-enhanced central core surrounded by a hyperenhanced rim (fibrous cap). To confirm the diagnosis, a multidetector computed tomography (MDCT) was performed; the MDCT showed a hyperdense mass with a hypodense center and a calcified peripheral rim. The central content had heterogeneous fluid density without significant contrast enhancement. The MDCT findings were considered highly suggestive of CMAC. CMR may be useful for the identification and definition of pericardial and myocardial masses and CMAC.

Update on the Organizational Aspects of Echocardiography in Italy (From Operator Training to the Report: 2007-2019): A Consensus Document by the "Società Italiana di Ecocardiografia e CardioVascular Imaging" Accreditation Area and Board 2017-2019.

In 2007, Società Italiana di Ecocardiografia e CardioVascular Imaging (SIECVI) already SIEC, published the document on the organization of echocardiography in Italy. In the years following the technological evolution, cultural and health factors have changed "the way, we do echo" as a tool for the different clinical pathways. The SIECVI Accreditation Area and Board 2017-2019 considered necessary to review and update the document in the light of innovation in the application of ultrasound for the heart disease assessment. In the document, we have considered the role of SIECVI in multimodal imaging, the need of training and certification of operators, the quality of echo machines, the accreditation of laboratories, the compilation of the report and its responsibility, and the presence of the sonographers in the EchoLab.

Bicuspid Aortic Valve Registry of the Italian Society of Echocardiography and Cardiovascular Imaging (REgistro della valvola aortica bicuspide della società italiana di ECocardiografia e CArdiovascular imaging): Rationale and Study Design.

BACKGROUND: Bicuspid aortic valve (BAV) is the most common congenital heart disease, affecting 0.5%-2% of the general population. It is associated not only with notable valvular risk (aortic stenosis and/or regurgitation, endocarditis) but also with aortopathy with a wide spectrum of unpredictable clinical presentations, including aneurysmal dilation of the aortic root and/or ascending thoracic aorta, isthmic coarctation, aortic dissection, or wall rupture. METHODS: The REgistro della Valvola Aortica Bicuspide della Società Italiana di ECocardiografia e CArdiovascular Imaging is a retrospective (from January 1, 2010)/prospective, multicenter, observational registry, expected to enroll 3000 patients with definitive diagnosis of BAV made by transthoracic and/or transesophageal echocardiography, computed tomography, cardiovascular magnetic resonance, or at surgery. Inclusion criteria were definitive diagnosis of BAV. Patients will be enrolled regardless of the presence and severity of aortic valve dysfunction or aortic vessel disease and the coexistence of other congenital cardiovascular malformations. Exclusion criteria were uncertain BAV diagnosis, impossibility of obtaining informed consent, inability to carry out the follow-up. Anamnestic, demographic, clinical, and instrumental data collected both at first evaluation and during follow-up will be integrated into dedicated software. The aim is to derive a data set of unselected BAV patients with the main purpose of assessing the current clinical presentation, management, and outcomes of BAV. CONCLUSIONS: A multicenter registry covering a large population of BAV patients could have a profound impact on the understanding of the natural history of this disease and could influence its management.

Fast 'wandering' Takotsubo syndrome: atypical mixed evolution from apical to mid-ventricular ballooning.

We report the case of a 53-year-old woman admitted for typical chest pain and a diagnosis of Takotsubo syndrome (TTS). Initial echocardiographic presentation was characterized by apical and mid-ventricular akinesis and basal hyper-kinesis. Unexpectedly, later after admission, echocardiography showed recovered apical akinesis with an apparent 'migration' of systolic dysfunction to mid-ventricular segment and hyper-kinesis of apical and basal segments. One week after admission, left ventricular contractility completely recovered and cardiac magnetic resonance imaging did not show signs of subendocardial late-enhancement and myocardial edema. Cases of TTS may therefore occasionally rapidly 'wander' within left ventricular segments, raising doubts over the so far used classification of left ventricular patterns of ballooning in subjects with TTS (typical/atypical). Apparently, different patterns can rapidly evolve into each other. The absence of late-enhancement at cardiac magnetic resonance imaging could hypothetically identify rapidly 'wandering' cases.
