Abstract

We propose a system solution to achieve data-efficient, decentralized state estimation for a team of flying robots using thermal images and inertial measurements. Each robot can fly independently, and exchange data when possible to refine its state estimate. Our system front-end applies an online photometric calibration to refine the thermal images so as to enhance feature tracking and place recognition. Our system back-end uses a covariance-intersection fusion strategy to neglect the cross-correlation between agents so as to lower memory usage and computational cost. The communication pipeline uses Vector of Locally Aggregated Descriptors (VLAD) to construct a request-response policy that requires low bandwidth usage. We test our collaborative method on both synthetic and real-world data. Our results show that the proposed method improves by up to 46 % trajectory estimation with respect to an individual-agent approach, while reducing up to 89 % the communication exchange. Datasets and code are released to the public, extending the already-public JPL xVIO library., Comment: 8 pages, 8 figures

Abstract

In the complex spectrum of coronary anomalies, the origin of the left coronary artery from the right sinus of Valsalva with intramural course could represent a catastrophic life-threatening condition leading to extensive myocardial infarction and sudden cardiac death, especially in young athletes. We report the case of a young female athlete with anomalous left coronary artery from the opposite sinus who survived a major non–ST-elevation myocardial infarction during the eighth kilometer of a running race. It was successfully treated by creating a neo-ostium of the left coronary artery in the left sinus at the point at which the artery left the aortic wall.

Abstract

Background: Cardiology divisions reshaped their activities during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to analyze the organization of echocardiographic laboratories and echocardiography practice during the second wave of the COVID-19 pandemic in Italy, and the expectations for the post-COVID era. Methods: We analyzed two different time periods: the month of November during the second wave of the COVID-19 pandemic (2020) and the identical month during 2019 (November 2019). Results: During the second wave of the COVID-19 pandemic, the hospital activity was partially reduced in 42 (60%) and wholly interrupted in 3 (4%) echocardiographic laboratories, whereas outpatient echocardiographic activity was partially reduced in 41 (59%) and completely interrupted in 7 (10%) laboratories. We observed an important change in the organization of activities in the echocardiography laboratory which reduced the operator-risk and improved self-protection of operators by using appropriate personal protection equipment. Operators wore FFP2 in 58 centers (83%) during trans-thoracic echocardiography (TTE), in 65 centers (93%) during transesophageal echocardiography (TEE) and 63 centers (90%) during stress echocardiography. The second wave caused a significant reduction in number of echocardiographic exams, compared to November 2019 (from 513 ± 539 to 341 ± 299 exams per center, −34%, p &lt, 0.001). On average, there was a significant increase in the outpatient waiting list for elective echocardiographic exams (from 32.0 ± 28.1 to 45.5 ± 44.9 days, +41%, p &lt, 0.001), with a reduction of in-hospital waiting list (2.9 ± 2.4 to 2.4 ± 2.0 days, −17%, p &lt, 0.001). We observed a large diffusion of point-of-care cardiac ultrasound (88%), with a significant increase of lung ultrasound usage in 30 centers (43%) during 2019, extended to all centers in 2020. Carbon dioxide production by examination is an indicator of the environmental impact of technology (100-fold less with echocardiography compared to other cardiac imaging techniques). It was ignored in 2019 by 100% of centers, and currently it is considered potentially crucial for decision-making in cardiac imaging by 65 centers (93%). Conclusions: In one year, major changes occurred in echocardiography practice and culture. The examination structure changed with extensive usage of point-of-care cardiac ultrasound and with lung ultrasound embedded by default in the TTE examination, as well as the COVID-19 testing.

42. Paget's Disease in Gynecomastia: Immunohistochemical Study of a Case

Author

Muretto, Pietro, Polizzi, Vincenzo, and Staccioli, M. Pia

Abstract

A case of Paget's disease and gynecomastia in a 70-year-old man is reported. Paget's disease was connected to an intraductal carcinoma, and the immunohistochemical study revealed similar positivity for cytokeratin A, carcinoembryonic antigen and epithelial membrane antigen in Paget cells and intraductal neoplastic cells whereas Paget cells resulted negative for cytokeratin B and C. The study using monoclonal anti-cytokeratin A (35 βH11), B (34 βE12) and C (34 βB4) could represent a good tool, supporting the theory of a ductal origin of Paget cells. A review of the literature has shown the rarity of Paget's disease in the male breast and revealed only two previous reports with an associated gynecomastia, in 2 patients with Klinefelter's syndrome and infiltrating breast carcinoma.

Abstract

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. [ABSTRACT FROM AUTHOR]

Abstract

Paradoxical low flow-low gradient aortic valve stenosis (AVS) is an increasing phenotype in the general population, particularly after the seventh decade of life. It is an AVS in which, despite the preserved ejection fraction, the mean transvalvular gradient is not suggestive of severe AVS (<40 mmHg). The pathophysiology is often intertwined with conditions resulting in heart failure with preserved ejection fraction, such as arterial hypertension and cardiac amyloidosis. Its management is rather controversial about the diagnosis and therapeutic management. The aims of this focus are: to clarify the role and reliability of the main available diagnostic methods, the efficacy of surgical and percutaneous treatments, and to develop a diagnostic-therapeutic algorithm for managing this condition in clinical practice. This algorithm will involve a multi-parametric evaluation, integrating standard echocardiographic assessment with three-dimensional planimetric valve area calculation, determination of the energy loss index), and calcium score calculation by computed tomography scan. This approach aims to ascertain the severity of the stenosis and determine the appropriate therapeutic management.

Abstract

Background: Transcatheter aortic valve implantation (TAVI) is emerging as an appealing management strategy for patients with severe aortic stenosis at intermediate, high or exceedingly high risk, but its risk-benefit profile in younger patients is less certain. We aimed to explore the outlook of patients aged 70 years or less and undergoing TAVI at 2 high-volume Italian institutions., Methods: We retrospectively collected baseline, imaging, procedural and outcome features of patients with age ≤70 years in whom TAVI was attempted at participating centers between 2012 and 2021. Non-parametric tests and bootstrap resampling were used for inferential purposes., Results: A total of 39 patients were included, out of >3000 screened with heart team involvement and >1500 receiving TAVI. Most common or relevant indications for TAVI reduced life expectancy (e.g. cardiogenic shock or severe left ventricular systolic dysfunction), chronic obstructive pulmonary disease, morbid obesity, active or recent extra-cardiac cancer, porcelain aorta, neurologic disability, cirrhosis, or prior surgical aortic valve replacement, as well as extreme cachexia, and Hutchinson-Gilford progeria. At least two contemporary high-risk features were present in most cases. Transapical access was used in 5 (12.8%) cases, and a sheathless approach in 15 (38.5%). A variety of devices were used, including both balloon- and self-expandable devices. Clinical outcomes were satisfactory, despite the high-risk profile, at both short- and mid-term, with no in-hospital death, and 5.1% (95% confidence interval 0-12.8%) mortality at a median follow-up of 15 months (minimum 1; maximum 85). Notably, no case of significant valve deterioration requiring reintervention occurred., Conclusions: In carefully selected patients with 70 years or less of age and prohibitive risk for surgery or reduced life expectancy, TAVI represents a safe option with a favorable mid-term survival and low rate of adverse events.

Abstract

Atrial myopathy is characterized by atrial fibrotic remodeling, together with electrical, mechanic and autonomic remodeling. Methods to identify atrial myopathy include atrial electrograms, tissue biopsy, cardiac imaging, and serum biomarkers. Accumulating data show that individuals with markers of atrial myopathy have an increased risk of developing both atrial fibrillation and strokes. The aim of the present review is to present atrial myopathy as a pathophysiologic and clinical entity, to describe methods for its detection and the possible implications on management and therapy in selected group of patients.

Abstract

Cardiac magnetic resonance (CMR) imaging has progressively become part of the imaging methods recommended in patients with heart failure. CMR represents the gold standard for assessing volumes, function, biventricular kinetics and providing tissue characterization through scans with and without contrast medium. In patients with heart failure with reduced ejection fraction (HFrEF) and ischemic dilated cardiomyopathy, CMR allows to search for viability, accurately estimate volumes and ejection fraction. It can assess scar extent for predicting response to cardiac resynchronization therapy and for establishing an indication for implanting a defibrillator in borderline cases. In patients with HFrEF and non-ischemic dilated cardiomyopathy, CMR helps to identify specific etiological subgroups and to estimate the arrhythmic risk beyond ejection fraction. In patients with heart failure with preserved ejection fraction, CMR offers the possibility of diagnosing specific phenotypes, including sarcomeric hypertrophic cardiomyopathy, amyloidosis or Fabry disease, and adds prognostic information. Both clinical and scientific interest in this imaging method is constantly expanding; the clinicians dealing with heart failure cannot fail to know the technique, the indications and all the potential that CMR can offer.

49. Transoesophageal echocardiography-guided 'primary' valve-in-valve technique in cardiogenic shock: a case report.

Author

Polizzi V, Cosma J, Cammardella A, Ranocchi F, and Musumeci F

Abstract

Background: Transcatheter aortic valve implantation inside a previously implanted bioprosthesis is an alternative treatment for patients with degenerated surgical aortic bioprosthesis (AB) at high surgical risk. Pre-operative computed tomography (CT) scan provides essential information to the procedure planning, although in case of acute presentation it is not always feasible., Case Summary: A 32-year-old man with history of surgical treatment of aortic coarctation and Bio-Bentall procedure was transferred to our department in cardiogenic shock with a suspected diagnosis of acute myocarditis. A transthoracic echocardiogram (TTE) revealed a severely impaired biventricular function and AB degeneration causing severe stenosis. It was decided to undertake an urgent trans-apical valve-in-valve (ViV) procedure. Due to haemodynamic instability, a preoperative CT scan was not performed and transoesophageal echocardiography (TOE) was the main intraprocedural guiding imaging technique. Neither intraprocedural nor periprocedural complications occurred. Serial post-procedural TTE exams showed good functioning of the bioprosthesis and progressive improvement of left ventricular ejection fraction. Patient was discharged from the hospital 8 days after the intervention., Discussion: A patient with cardiogenic shock due to severe degeneration of the AB was treated with urgent transapical ViV procedure. In this case, where urgent ViV technique was needed, TOE appeared to be a crucial alternative to CT scan and allowed us to perform a successful procedure., (© The Author(s) 2021.
