Perioperative echocardiography in minimally invasive surgery for hypertrophic obstructive cardiomyopathy.

Background: Hypertrophic obstructive cardiomyopathy (HOCM) is clinically symptomatic and prone to malignant arrhythmias and sudden cardiac death (SCD). Currently, an effective treatment is surgical resection of the hypertrophic ventricular septum to relieve the left ventricular outflow tract (LVOT) obstruction and mitral insufficiency. Our center performs an innovative, minimally invasive right infra-axillary thoracotomy for transaortic septal myectomy.

Mitral Geometry on the Mechanism of Left Ventricular Outflow Tract Obstruction in Hypertrophic Cardiomyopathy.

Objective: The mechanism of left ventricular outflow tract obstruction (LVOTO) is complex in hypertrophic cardiomyopathy (HCM). We aimed to evaluate the impact of mitral valve geometry on LVOTO by echocardiography.

Materials And Methods: The study population comprised 177 consecutive patients with HCM.

Preliminary exploration of theory and practice training of 5G ultrasonic remote consultation in grassroot hospitals.

Background: With the rapid development of science and technology, telemedicine diagnosis and treatment systems have gradually attracted increased attention and applications.5G ultrasound is an important branch of telemedicine, connecting grassroots hospitals at one end and provincal hospitals at the other, which provides remote guidance to grassroots doctors for ultrasound examination and image diagnosis. It is convenient for villagers obtaining diagnosis and advice from provincial ultrasound experts, saving time and economic costs, as well as benefiting from high-quality ultrasound medical resources.

Mechanism by which salt stress induces physiological responses and regulates tanshinone synthesis.

Salvia miltiorrhiza is a traditional Chinese herbal medicine with tanshinone as one of the main bioactive components and has antitumor, antibacterial, anti-inflammatory properties, as well as other physiological functions. Tanshinone, as a secondary metabolite, is synthesized under salt stress or other environmental stresses. Oxidative stress is an important physiological response of plants to salt stress.

Pulmonary arteriovenous fistula diagnosed by transthoracic contrast echocardiography: A case report.

We report the case of a 38-year-old woman who was admitted due to right limb numbness. A right-to-left shunt (RLS) was detected by transthoracic contrast echocardiography (cTTE), and microbubbles appeared in the left heart seven cardiac cycles after opacification of the right heart, suggesting pulmonary arteriovenous fistula. This was supported by computed tomography angiography.

Diagnosis and treatment of infective endocarditis in pregnancy: a case report.

Background: Pregnancy with infective endocarditis (IE) is rare, but the fetal and maternal mortality rates of these pregnancies are very high, making IE a serious threat to the safety of pregnant women and their fetuses. Therefore, for pregnant women with recurrent fever, a detailed medical history and physical examination should be performed, echocardiography and blood culture should be carried out as soon as possible, multidisciplinary consultation should be implemented, and a diagnosis and treatment plan should be formulated right away, as this is key to saving the lives of mothers and infants.

Case Introduction: A 30-year-old pregnant Chinese woman had IE at 26 weeks of gestation.

Mammography and ultrasound effective features in differentiating basal-like and normal-like subtypes of triple negative breast cancer.

The aim of our study was to find effective features of mammography and ultrasound in differentiating Basal-like breast cancer (BBC) and Normal-like breast cancer (NBC), two subtypes of triple negative breast cancer (TNBC). From January 2014 to March 2017, we retrospectively reviewed 91 patients who were pathologically confirmed as TNBC. According to immunohistochemical cytokeratin 5/6 (CK5/6) and Epidermal Growth Factor Receptor (EGFR), TNBCs were classified into BBCs group and NBCs group.
