The clinical distinction between athlete's heart and structural heart disease in the echocardiography laboratory is often challenging. We present a case where athletic heart syndrome was promptly differentiated from pathology with a simple maneuver during echocardiography.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.

Obesity is associated with an increased cardiovascular risk. This study aimed to assess the role of echocardiography in the early detection of subclinical cardiac abnormalities in a cohort of obese patients with a preserved ejection fraction (EF) undergoing bariatric surgery.

Forty consecutive severely obese patients (body mass index≥35 kg/m2) referring to our center for bariatric surgery were enrolled in this prospective cohort study. Despite a baseline EF of 61% ± 3%, almost half patients (43%) had a systolic dysfunction (SD) defined as global longitudinal strain (GLS)>-18%, and most of them (60%) had left ventricular hypertrophy (LVH) or concentric remodeling (CR). At 10-months after surgery, body weight decreased from 120 ± 15 kg to 83 ± 12 kg, body mass index from 44 ± 5 kg/m

to 31 ± 5 kg/m

(both

< 0.001). Septal and left ventricular posterior wall thickness decreased respectively from 10 ± 1 mm to 9 ± 1 mm (

= 0.004) and from 10 ± 1 mm to 9 ± 1 mm (

= 0.007). All systolic parametersectable with echocardiography. Bariatric surgery is associated with reverse cardiac remodeling; it might also have a preventive effect on atrial fibrillation occurrence by reducing its substrate.

Various clinical trials provide evidence about the safety, effectiveness, and therapeutic success of percutaneous left atrial appendage closure (LAAC) using various occlusion devices. These devices are foreign materials implanted into the left atrium and may deteriorate left atrial (LA) function. The aim of this study was to evaluate the change in transesophageal echocardiography (TEE)-derived LA strain after LAAC.

The study included 95 patients (age 75 ± 6.7 years, 67% male) who underwent percutaneous LAAC. LA strain was evaluated at three different time intervals by TEE (baseline, 45 days, and 180 days after the procedure). All data were analyzed using the software Image-Arena (TomTec

). JAK inhibitor Seventy patients had atrial fibrillation, whereas 25 were in sinus rhythm at baseline and during follow-up. Analysis was performed for peak atrial longitudinal strain (PALS) and peak atrial contraction strain (PACS) from segments of the lateral wall in mid-esophageal four-chamber view. PACS was obtained in patients with sinus rhythm during examinations. Compared to baseline, PALS increased at 45 days after the procedure (12.4% ± 8.4% at baseline vs. 16.0% ± 10.6% after 45 days,

= 0.001) and remained stable from 45 days to 180 days after procedure (13.8% ± 9.1% after 45 days vs. 17.2% ± 12.6% after 180 days,

= 0.092). Similarly, PACS increased at 45 days after the procedure (5.8% ± 3.9% at baseline vs. 10.6% ± 7.6% after 45 days,

= 0.001) and remained stable from 45 days to 180 days after the procedure (7.6% ± 4.5% after 45 days vs. 7.9% ± 3.1% after 180 days,

= 0.876).

Our study demonstrated for the first time the improvement in TEE-derived LA strain following LAAC within 45 days of implantation. The findings suggest improved LA function following LAAC.

Apart from physiological variants and structural normal mimickers, echocardiography can detect principal intracardiac masses such as neoplasms, thrombi, vegetation, and extracardiac masses such as metastatic lesions. Moreover, transesophageal echocardiography can provide further details and provide higher accuracy in case a deeper examination of the mass is needed. This review will focus on the systematic evaluation of intra-/extracardiac masses including epidemiology and morphological and echocardiographic features, providing practical and technical tips to health-care professionals to achieve correct identification of the masses. General data on cardiac masses were extracted via PubMed/MEDLINE search engine from indexed reviews, original studies, and clinical case reports. The echocardiographic features of cardiac masses were reviewed according to the most relevant international cardiology and echocardiography scientific societies' position statements.The epidemic of COVID-19 has grown to pandemic proportions and the preventive and mitigation measures have been widely spread through the media. The cardiologists are called as consultants for the cardiovascular pathologies and echocardiography is a fundamental examination in many clinical situations, but not without risks for health staff. Società Italiana di Ecocardiografia e CardioVascular Imaging Council has decided to formulate a document aimed to highlight the importance of a correct indication and execution procedure of the echocardiogram during a COVID-19 pandemic.Polyethyleneimine (PEI) glutaraldehyde-refined calcium pectinate (CaP)-agar beads were presented as improved covalent immobilization matrices. The CaP-agar beads exhibited incremented mechanical stability which facilitated their handling. The beads' concoction and activation processes were honed using the Box-Behnken design which recommended utilizing 5.4% agar, and a 2.95% PEI solution of pH 8.67. The honed CaP-agar beads established a more efficient ionic interaction with PEI which enabled the immobilization of more enzyme while utilizing less PEI than that required to activate the neat CaP beads. Furthermore, the activated CaP-agar beads granted superior operational stability to the immobilized enzyme, β-d-galactosidase (βgal), where it preserved 86.84 ± 0.37% of its precursive activity during its thirteenth reusability round. The CaP-agar immobilized βgal (iβgal) also showed incremented storage stability where it preserved 85.05 ± 3.32% of its precursive activity after 38 days of storage. The thermal stability of the iβgal was shown to be superior to that of the free enzyme as the iβgal exhibited incremented thermodynamic parameters, such as the t1/2 values, the D values, the thermal denaturation activation energy, the enthalpies, and the Gibb's free energies.
