Secretory carcinoma in the breasts, frequently reveals the functions involving low grade, multiple negative chest carcinoma- A Case record along with current report on books.
Transcatheter aortic valve replacement (TAVR) is an alternative treatment option for patients with severe aortic stenosis. Although rarely described, mitral valve perforation because of mechanical stimulation due to low deployment of the prosthesis and the association with infective endocarditis, are potentially life-threatening complications that physicians should be aware of because patients should not be suitable for further surgical or percutaneous management. Herein, we present a case of an 88-year-old man presenting with worsening heart failure 6 months after TAVR. We discuss the diagnostic process and the therapeutic issues. Finally, we underline the invaluable role of echocardiography during TAVR procedures, due to its ability in detecting early complications and avoiding incorrect prosthetic deployment.An 88-year-old male with nonvalvular atrial fibrillation (NVAF) and severe congestive heart failure (HF), was admitted to the Neurological Intensive Care Unit because of the acute onset of aphasia and left hemiplegia. Transthoracic echocardiography revealed a left atrial (LA) cavity thrombus. Its "fatal" distal embolization to abdominal aorta occurred in a few days. These observations should lead to a cautious approach in proposing a percutaneous closure of LA appendage in older NVAF patients, with HF and/or left ventricular dysfunction and larger LA volumes, who are not adequately anticoagulated.Cardiac angiosarcoma is the most common among primary malignant cardiac tumors in adults. Malignant cardiac tumors commonly arise in the right-sided cardiac chambers unlike benign tumors that commonly arise in the left-sided chambers. Cardiac tumors on the left side need to be carefully assessed for malignant features for deciding treatment strategy and prognostication. We present the case of a 62-year-old female with a large left atrial mass infiltrating the interatrial septum and adjacent myocardial wall. Histology was suggestive of angiosarcoma. Although a radical excision was done, the tumor recurred within 6 months of the postoperative period and she died shortly after the recurrence.Single atrium (SA) is one of the rare congenital anomalies in which there is a complete absence of the atrial septum without an endocardial cushion defect associated with the absence of malformation of the atrioventricular (AV) valves. The term "common atrium" is used to denote the condition where there is a complete absence of the atrial septum or it is represented by a small strand of tissue present at the superior atrial wall of the common chamber, absence of interventricular communication, and accompanying AV cushion defect. Our patient demonstrated typical echocardiographic features of three-chambered heart (SA), which is a rare entity.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
). 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. Methotrexate datasheet 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. The βgal's immobilization onto the activated CaP-agar beads also shifted the enzyme's optimal pH from 4.6-5.1 to 3.3-4.9, whereas its optimal temperature was retained at 55 °C. The procured biocatalyst was exploited to efficiently hydrolyze the lactose in whey permeate.One of the characteristic features of obesity is increased body weight and accumulation of adipose tissue. It is associated with low grade inflammation and gut dysbiosis. Probiotics and its products could be an ideal strategy to prevent or treat diabetes. In the present study, animals were induced obesity by providing them with high fat diet. Three purified bacteriocins i.e., DT24, PJ4 and TSU4, previously isolated and purified from various probiotic strains, were given as treatment strategies, following the induction of obesity. Upon the completion of the study, animals were sacrificed and were checked for their tissue expression of inflammatory mediators and adipokines. Serum hormone and cytokines analysis were performed to check their inflammatory state. Treatment with purified bacteriocin DT24 did not show any therapeutic effect in any of the parameter studied. Bacteriocin TSU4 on the other hand showed better reversal compared to DT24. Bacteriocin PJ4 showed the most promising results by reversing all the altered parameters significantly. It significantly reversed all the biochemical, immunological in terms of serum cytokines as well as altered morphological characteristics. PJ4 can be further explored to determine its mode of action. The anti-microbial proteins or to be more specific, bacteriocins, which shows broad spectrum efficacy, could be a better alternative in modulating gut microflora for the treatment of obesity and diabetes characteristics. The efficacy of bacteriocin PJ4 may also be due to the source of the host of Lactobacillus.
