RESUMO

The availability of miniaturized ultrasound machines has changed our approach to many cardiovascular diseases. Handheld ultrasound imaging can be performed at the bedside, it is easy to use, and the information provided, although limited, is of unquestionable importance for a quick diagnosis that leads to early treatment. They have unique characteristics: Low cost, wide availability, safety, accuracy, and can be used in different clinical scenarios and by operators with different backgrounds. Image acquisition and interpretation is rapid and provides, in each situation, useful information for diagnosis, prognosis, and clinical and therapeutic management. This review focuses on the use of handheld ultrasound devices, describes differences with other equipment, their limitations, and the numerous advantages derived from their use.

RESUMO

Sympathetic nervous system plays a pivotal role in essential hypertension and in the development of left ventricular hypertrophy. Moreover, cardiac sympathetic dys-regulation has been demonstrated as a key con-causal factor in the genesis and progression of pathologic conditions such as congestive heart failure and ischemic heart disease to which hypertension predisposes as a risk factor. However, despite its fundamental role in cardiac pathophysiology, the evaluation of cardiac sympathetic nervous system has never gained a wide clinical application, remaining mostly a research tool. In this context, nuclear imaging techniques are the only modalities to allow the direct evaluation of cardiac sympathetic nervous integrity, giving the chance to obtain objective measures of the sympathetic tone. This review, while summarizing the general profile of currently available tests for autonomic evaluation, focuses on 123I-metaiodobenzylguanidine nuclear imaging as a preferential tool to assess cardiac sympathetic status. Specifically, the review discusses the available evidence on cardiac 123I-metaiodobenzylguanidine scintigraphy in arterial hypertension and left ventricular hypertrophy and its diagnostic and prognostic potential in congestive heart failure and ischemic heart disease.

RESUMO

AIM: Functional analysis and measurement of left atrium are an integral part of cardiac evaluation, and they represent a key element during non-invasive analysis of diastolic function in patients with hypertension (HT) and/or heart failure with preserved ejection fraction (HFpEF). However, diastolic dysfunction remains quite elusive regarding classification, and atrial size and function are two key factors for left ventricular (LV) filling evaluation. Chronic left atrial (LA) remodelling is the final step of chronic intra-cavitary pressure overload, and it accompanies increased neurohormonal, proarrhythmic and prothrombotic activities. In this systematic review, we aim to purpose a multi-modality approach for LA geometry and function analysis, which integrates diastolic flow with LA characteristics and remodelling through application of both traditional and new diagnostic tools. METHODS: The most important studies published in the literature on LA size, function and diastolic dysfunction in patients with HFpEF, HT and/or atrial fibrillation (AF) are considered and discussed. RESULTS: In HFpEF and HT, pulsed and tissue Doppler assessments are useful tools to estimate LV filling pressure, atrio-ventricular coupling and LV relaxation but they need to be enriched with LA evaluation in terms of morphology and function. An integrated evaluation should be also applied to patients with a high arrhythmic risk, in whom eccentric LA remodelling and higher LA stiffness are associated with a greater AF risk. CONCLUSION: Evaluation of LA size, volume, function and structure are mandatory in the management of patients with HT, HFpEF and AF. A multi-modality approach could provide additional information, identifying subjects with more severe LA remodelling. Left atrium assessment deserves an accurate study inside the cardiac imaging approach and optimised measurement with established cut-offs need to be better recognised through multicenter studies.

RESUMO

Coronary computed tomography angiography is a noninvasive heart imaging test currently undergoing rapid development and advancement. The high resolution of the three-dimensional pictures of the moving heart and great vessels is performed during a coronary computed tomography to identify coronary artery disease and classify patient risk for atherosclerotic cardiovascular disease. The technique provides useful information about the coronary tree and atherosclerotic plaques beyond simple luminal narrowing and plaque type defined by calcium content. This application will improve image-guided prevention, medical therapy, and coronary interventions. The ability to interpret coronary computed tomography images is of utmost importance as we develop personalized medical care to enable therapeutic interventions stratified on the bases of plaque characteristics. This overview provides available data and expert's recommendations in the utilization of coronary computed tomography findings. We focus on the use of coronary computed tomography to detect coronary artery disease and stratify patients at risk, illustrating the implications of this test on patient management. We describe its diagnostic power in identifying patients at higher risk to develop acute coronary syndrome and its prognostic significance. Finally, we highlight the features of the vulnerable plaques imaged by coronary computed tomography angiography.

RESUMO

BACKGROUND: We prospectively assessed the incremental value of a pocket-sized echocardiography (PSE) device during cardiology consultations, in addition to physical examination, ECG reading, and chest x-ray. METHODS: A total of 443 consecutive patients (53% men), referred for bedside consultations, underwent physical examination, ECG, and CXR, followed by PSE examination. The physician completed a detailed questionnaire (clinical and echocardiographic data, scanning time, abnormal results). Receiver operating characteristic (ROC) curve analysis was generated to test the predictive discrimination value of the different methods. The incremental value of PSE examination compared to clinical visit alone or combined with ECG results was expressed as a global chi-square value. RESULTS: The PSE examination did not influence the definitive diagnosis in only 23.5% of cases, while 25.3% of the diagnoses were confirmed and verified by PSE. The clinical diagnosis was enriched by PSE in 21.9% of cases, and the diagnosis was changed in 26.2%. The area under curve (AUC) of physical examination + ECG results (sensitivity: 80%; specificity: 67%) was significantly higher than physical examination alone (sensitivity: 75%; specificity: 62%) (P < 0.0002), and the AUC of PSE results (sensitivity: 88%; specificity: 86%) was significantly higher than physical examination + ECG results (P < 0.0001). The PSE results, combined with clinical and ECG results, had a significant incremental diagnostic value during cardiology consultation when compared to the clinical visit alone or with ECG results (P < 0.0001). CONCLUSIONS: PSE had an incremental diagnostic value during bedside cardiology consultation, increasing the number of appropriate diagnoses and reducing the routine use of echocardiography.

RESUMO

Cardiac involvement in sickle beta thalassemia (Sß-thal) patients has been poorly investigated. We aimed to evaluate cardiac function and myocardial iron overload by cardiovascular magnetic resonance (CMR) in patients with Sß-thal. One-hundred and eleven Sß-thal patients consecutively enrolled in the Myocardial Iron Overload in Thalassemia (MIOT) network were studied and compared with 46 sickle cell anemia (SCA) patients and with 111 gender- and age- matched healthy volunteers. Cine images were acquired to quantify biventricular function. Myocardial iron overload (MIO) was assessed by the T2* technique, while macroscopic myocardial fibrosis was evaluated by the late gadolinium enhancement (LGE) technique. In Sß-thal and SCA patients, the morphological and functional CMR parameters were not significantly different, except for the left atrial area and left ventricular (LV) stroke volume, indexed by body surface area (p = 0.023 and p = 0.048, respectively), which were significantly higher in SCA patients. No significant differences between the two groups were found in terms of myocardial iron overload and macroscopic myocardial fibrosis. When compared to healthy subjects, Sß-thal patients showed significantly higher bi-atrial and biventricular parameters, except for LV ejection fraction, which was significantly lower. The CMR analysis confirmed that Sß-thal and SCA patients are phenotypically similar. Since Sß-thal patients showed markedly different morphological and functional indices from healthy subjects, it would be useful to identify Sß-thal/SCA-specific bi-atrial and biventricular reference values.

RESUMO

Background: Many data were published about Long-Covid prevalence, very few about the findings of new cardiac alterations (NCA) in COVID-19-recovered people. ARCA-post-COVID is an observational study designed to investigate the prevalence of NCA in patients recovered from Covid-19.Methods: from June 2020 to December 2022, we enrolled 502 patients with a positive nasopharyngeal swab for SARS-CoV2 and a subsequent negative one. We performed anamnesis, lab-test, and routine cardiological tests (ECG, Holter, TTE). Results: The median age was 56 years (IQR 44-67); women were 52.19%; in the acute phase 24.1% of patients were treated in a medical department, 7.2% in the ICU and the others at home. At the visit, 389 patients (77.49%) complained of a broad range of symptoms. We reported patients' characteristics according to the course of the disease and the persistence of symptoms. NCA were found in 138 patients (27.49%): among them 60 cases (11.95%) of pericardial effusion. Patients with NCA were older (median 60y, IQR: 47-72, vs median 56y, IQR 42-65), had a higher prevalence of smokers (27% vs 17%; p0.014), CAD (11% vs 6%; p0.048) and stroke/TIA (3.6% vs 0.3%; p0.002) and a lower prevalence of hypercholesterolemia (18% vs 30%; p0.007). The prevalence of NCA seems constant with different subtypes of the virus. Conclusion: the prevalence of NCA in patients who recovered from COVID-19 is high and constant since the beginning of the pandemic; it is predictable based on hospitalization and long-lasting symptoms (9.64%-42.52%). Patients with one of these characteristics should undergo cardiological screening.

RESUMO

Hypereosinophilic syndrome (HES) is a systemic disorder with various manifestations, characterized by hypereosinophilia and caused by primary or secondary conditions. Loeffler's endocarditis (LE) represents a frequent cardiac manifestation of HES, caused by infiltration of the myocardium by eosinophilic cells, which determines endocardial damage, with subsequent inflammation, thrombosis, and fibrosis of either one or both ventricles. The diagnosis of cardiac involvement is based on a multimodality approach (i.e., two-dimensional transthoracic echocardiography [2D-TTE], speckle-tracking echocardiography [STE], and cardiac magnetic resonance [CMR]), with different findings depending on the stage of disease. STE may be useful in the initial phase when traditional imaging techniques may result negative, whereas CMR allows myocardial tissue characterization along with a better definition of the right ventricle. We present a rare case of LE with isolated right ventricular involvement in a patient with HES caused by chronic eosinophilic leukemia with constitutively activated fusion tyrosine kinase on chromosome 4q12, successfully treated with imatinib mesylate.

RESUMO

Nonbacterial thrombotic endocarditis (NBTE) is a rare condition that refers to a spectrum of noninfectious lesions of cardiac valves that is most commonly seen in advanced malignancy. We describe a case report of a 63-year-old male with NBTE and multiple embolizations (encephalic, coronary, splenic, and renal). The patient was admitted to the emergency department for stroke. During hospitalization, the patient complained of left leg pain and a venous echo color Doppler of the lower limbs was performed, showing bilateral distal deep-vein thrombosis. A thoracoabdominal computed tomography scan, which was performed to rule out pulmonary embolism, revealed a primary lung cancer and subcarinal lymphadenopathy. As collateral findings, multiple ischemic lesions in the spleen and in both kidneys were identified. In addition, areas of subendocardial hypodensity compatible with ischemia were also highlighted. An electrocardiogram showed acute myocardial infarction and focused echocardiographic evaluation displayed hypokinesis of the lateral and posterior in the mid- and distal segments and aortic and mitral valve vegetations, confirmed by a transesophageal echocardiography. Empiric antimicrobial therapy was started; all blood culture sets were negative and the patient was apyretic throughout the hospitalization. These findings supported the hypothesis of NBTE with multiple embolizations during a hypercoagulable state associated with advanced lung cancer.

RESUMO

Pneumonia is the most commonly described manifestation of Legionella pneumophila infection (legionellosis), and extrapulmonary manifestations are uncommon. There are a few descriptions of acute myocarditis associated with legionellosis. We present a case of acute myocarditis in a patient admitted for legionellosis with multisystemic involvement (lung, heart, and kidney). Left ventricular (LV) dysfunction was documented by cardiac magnetic resonance (CMR) and two-dimensional speckle-tracking echocardiography; layer-specific strain analyses were performed, which allowed to differentiate subendocardial or subepicardial contractile impairment. Layer-specific strain analyses by echocardiography demonstrated impairment of subepicardial deformation in the inferolateral wall, which mirrored CMR findings, showing late gadolinium enhancement in the subepicardium of the same LV segments. After initiation of appropriate antibiotic therapy with levofloxacin, LV systolic function rapidly improved as assessed by both CMR and strain analyses, with concomitant normalization of both clinical and biochemical abnormalities. The basic mechanisms of myocardial involvement during legionellosis are unclear; we discussed our findings according to the limited available evidence.

RESUMO

Primary cardiac lymphoma (PCL) is among the rarest heart neoplasms. Its estimated incidence is about 1%-2% among primary cardiac tumor and 0.5% of extranodal lymphoma. It usually causes heart failure, pericardial effusion, tamponade, and arrhythmias. Prognosis is poor; treatment is combined medical and surgical. We described the case of a 62-year-old male with PLC that presented with syncope and cardiac tamponade, submitted to R-CHOP therapy because of failure of surgery. Clinical state is stable 3 months after diagnosis and first chemotherapy cycle.

RESUMO

Pseudoaneurysm complicated by aortopulmonary fistula (APF) after a Bentall procedure is extremely rare but potentially fatal, so timely diagnosis and treatment are critical. We present a subacute case of a post-traumatic APF which has had initial aspecific symptoms and later an acute worsening heart failure with chest pain not responding to medical treatment and requiring emergency surgery.

RESUMO

Transitional atrioventricular (AV) septal defects are uncommon congenital heart defects, and diagnosis is usually made in childhood. We present the case of intermediate AV canal diagnosed in a man referring to cardiological examination for the first time in his life at the age of fifty for exertional dyspnea. The absence of medical examination or execution of electrocardiogram or echocardiogram in childhood or in youth and the very late appearance of symptoms lead to a late diagnosis of this congenital heart disease (CHD). This case underlines the importance of including CHD in the differential diagnosis of symptoms such as chronic dyspnea, also in adulthood.

RESUMO

BACKGROUND: Patent foramen ovale (PFO) is present in as many as 25% of the general population and is considered an irrelevant condition in healthy subjects. Here, we sought to determine an association between an asymptomatic PFO at baseline and postoperative short-term adverse events in patients undergoing major pulmonary resection for lung cancer. In addition, we evaluated for the rate of PFO after pulmonary resections. METHODS: This prospective, observational study assessed patients by transcranial Doppler with contrast at baseline and discharge. To confirm interatrial shunting, patients with positive transcranial Doppler at baseline also underwent contrast transthoracic echocardiography. Multivariate logistic regression models were adopted to investigate for independent factors that could have been associated with complications. Backward stepwise procedure was used for model selection. RESULTS: Median age was 67.7 ± 9.2 years (range, 36 to 86), and 67% were men. Overall, 18 patients underwent pneumonectomy, 11 bilobectomy, and 118 lobectomy; 54% underwent right-sided procedure and 46%, left-sided. One perioperative death was recorded, and 34 patients had one or more cardiopulmonary complications. At baseline, PFO was positive in 25% (37 of 147) and negative in 75% (110 of 147); of the latter, 11% were positive at discharge. Detection of PFO at baseline, on multivariate analysis, was significantly associated with a risk of postoperative complications (odds ratio 2.5; 95% confidence interval: 1.1 to 5.8). Specifically, we observed a significant association between atrial fibrillation and positive PFO at baseline (odds ratio 3.5; 95% confidence interval: 1.4 to 9.0). CONCLUSIONS: Preoperative asymptomatic PFO was independently associated with postoperative adverse events. Moreover, 11% of patients who had negative transcranial Doppler studies at baseline had asymptomatic PFOs at discharge. Larger prospective studies are needed to further investigate for a prognostic impact of PFO in thoracic surgery.

RESUMO

Cardiovascular imaging has radically changed the management of patients with arrhythmogenic cardiomyopathies. This article focuses on the role of echocardiography and MRI in the diagnosis of these structural diseases. Cardiomyopathies with hypertrophic pattern (hypertrophic cardiomyopathy, restrictive cardiomyopathies, amyloidosis, Anderson-Fabry disease, and sarcoidosis), cardiomyopathies with dilated pattern, inflammatory cardiac diseases, and right ventricular arrhythmogenic cardiomyopathy are analyzed. Finally, anatomic predictors of arrhythmias and sudden cardiac death are discussed. Each paragraph is attended by clinical cases that are discussed on the electrocardiogram, after integrated with the anatomic, functional, and hemodynamic modifications of cardiovascular imaging.

RESUMO

Despite the availability of anti-hypertensive medications with proven efficacy and good tolerability, many hypertensive patients have blood pressure (BP) levels not at the goals set by international societies. Some of these patients are either non-adherent to the prescribed drugs or not optimally treated. However, a proportion has resistant hypertension (RH) defined as office BP above goal despite the use of ≥3 antihypertensive medications at maximally tolerated doses (one ideally being a diuretic). Diagnosis of RH based upon office measurements, however, needs confirmation through 24-h BP monitoring to exclude "white coat" RH since cardiovascular events and mortality rates follow mean ambulatory BPs. Standardized combination therapy based upon angiotensin converting enzyme inhibitors or angiotensin receptor blockers, amlodipine or other dihydropiridine calcium channel blockers and thiazide or thiazide-like diuretics has been advocated to treat RH with spironolactone as preferred fourth add-on drug. Interventional procedures such as renal denervation have been devised to treat RH and tested with insofar not positive results in series of patients not responding to medical treatment. It is unclear whether RH constitutes a specific phenotype of EH or should rather be considered a more serious form of uncontrolled hypertension. Whatever the case, its presence associates with an increased cardio- and cerebrovascular risk and deserves, therefore, particular care.

RESUMO

: Structural changes in left and right cardiac chambers that occur in arterial hypertension (AH) may lead to an increased risk of atrial fibrillation. Considering that AH is currently the most common cardiovascular disease in the general population, it represents a major risk factor for atrial fibrillation development. This review explores the complex relationship between atrial fibrillation and AH, starting from its pathophysiological basis. It focuses on the role of echocardiography in the management of hypertensive and atrial fibrillation patients, with emphasis on what should be evaluated about left ventricular remodeling, diastolic and systolic function, left atrial (LA) size and function and right ventricular deformation in patients with AH.

RESUMO

The prevalence of chronic heart failure (CHF) is steadily increasing. Both sexes are affected, with significant differences in etiology, epidemiology and clinical presentation, prognosis, comorbidities, and response to treatment. Women tend to develop CHF at a more advanced age, present more often with HF with preserved ejection fraction, are more symptomatic, and have a worse quality of life than men, but also a better prognosis. In women, CHF has more frequently a non-ischemic etiology, and arterial hypertension and diabetes mellitus are leading comorbidities. Furthermore, many sex-related differences have been detected in the response to treatment, for example a greater prognostic benefit from angiotensin-receptor blockers in women, a higher incidence of complications after defibrillator implantation, and a greater response to cardiac resynchronization therapy. Furthermore, women are less likely to receive defibrillator therapy or heart transplantation. The significant underrepresentation of women in clinical trials limits our capacity to evaluate the extent of sex-related differences in CHF, although their characterization seems crucial in order to achieve the ultimate goal of a tailored therapy for this condition.

RESUMO

Pericardial cysts (PCs) are very rare, often congenital, mediastinal masses. Usually, they are located in the right cardiophrenic angle and only in 8% of cases in the anterior or posterior mediastinum. Computed tomography and/or magnetic resonance imaging are accurate tools for the diagnosis and characterization of mediastinal masses. However, echocardiography is, in many cases, a good screening technique. If asymptomatic, they do not require surgical excision. The authors describe a case of posterior mediastinum PC; in these cases, echocardiography cannot see the mass and three-dimensional imaging techniques are required. The clinical management of this case is discussed.
