PURPOSE: For assessing the severity of tricuspid regurgitation (TR), there is no gold standard. We developed a parameter, the right ventricular systolic force ratio-RIVIERA, using the continious wave Doppler analysis of TR and pulsed-wave analysis of the right ventricle outflow tract. We hypothesized that the RIVIERA would facilitate the ability to identify severe TR in clinical settings. MATERIALS AND METHODS: We obtained data from routine transthoracic echocardiograms...

PURPOSE: The purpose of this study was to evaluate the value of diagnosing delaminated tears and ultrasonic characteristics on real-time dynamic ultrasound. MATERIALS AND METHODS: We enrolled 143 consecutive patients who underwent arthroscopic rotator cuff repair between April 2020 and January 2021. All patients were examined using real-time dynamic ultrasound of the shoulder within 2 weeks before arthroscopy. In our study, delaminated tears were defined as intratendinous horizontal splitting with or without the retraction of the articular or bursal layer of tendon...

This case describes the successful use of transcranial color-coded duplex sonography (TCCD) to diagnose a posterior circulation aneurysm in a patient with subarachnoid hemorrhage. A 33-year-old, was admitted to the ICU after a brain CT scan showed peritroncal subarachnoid hemorrhage. TCCD revealed a rounded image with color Doppler near the P1 portion of the right posterior cerebral artery, which was later confirmed to be a 4 mm aneurysm at the right posterior inferior cerebellar artery (PICA). The aneurysm was treated with coil exclusion and TCCD confirmed its disappearance post-treatment...

Conditions other than stenosis also disturb the coronary flow. Such conditions include the coronary slow flow phenomenon, coronary artery ectasia, and coronary artery tortuosity. Evidence exists regarding myocardial dysfunction in these conditions. In this review, we present studies that have used speckle-tracking echocardiography to determine whether coronary flow disturbances are accompanied by myocardial dysfunction. Additionally, we seek to show the gaps in knowledge concerning this issue and the dimensions that future studies should consider...

INTRODUCTION: To explore the diagnostic value of spatiotemporal image correlation (STIC) for different types of fetal conotruncal defects (CTDs). METHODS: The clinical data and STIC images of 174 fetuses with CTDs diagnosed via prenatal ultrasound were analyzed retrospectively. RESULTS: Among the 174 cases of CTDs, 58 were tetralogy of Fallot (TOF); 30, transposition of great arteries (TGA) (D-TGA, 23 cases; cc-TGA, 7 cases); 26, double outlet of the right ventricle (DORV); 32, persistent arterial trunk (PTA) (type A1, 15 cases; type A2, 11 cases; type A3, 5 cases; type A4, 1 case); and 28, pulmonary atresia (PA) (ventricular septal defect, 24 cases; ventricular septal integrity, 4 cases)...

Color Doppler (CD) is an established diagnostic modality for bladder exstrophy. We present two mid-trimester difficult-to-diagnose cases with no obvious infraumbilical mass bulge, assessed by CD in sagittal and axial pelvic views. The first case was a classical bladder exstrophy at 19 weeks nestled under the umbilical-cord and the second case was an omphalocele-exstrophy-imperforate-anus-spinal complex at 18 weeks 4 days gestation with exstrophic bladder embedded under the omphalocele. The altered course of umbilical arteries in relation to pelvic bony landmarks seen in these fetuses could be an objective approach to complement mid-trimester diagnosis of bladder exstrophy regardless of mass bulge...

This case image illustrates the importance of new sonographic applications such as superb microvascular imaging and shear wave elastography; as showed, they improve the diagnostic recognition of peripheral nerve lesion thanks to a better definition of vascularity and measure of stiffness.

Primary squamous cell carcinoma of the liver (PSCCL) is rare. PSCCL's lack of specific clinical manifestations and laboratory tests necessitate preoperative diagnosis via imaging examination. Conventional ultrasound (US) demonstrates a mass with mixed echogenicity, and contrast-enhanced US shows a circular pattern of "fast forward, fast backward or slow backward, high enhancement." Enhanced computed tomography (CT) showed enhancement in the center or edge of the lesion, and the density of the enhanced lesion was lower than that of the liver tissue in the same layer...

Ultrasonography and computed tomography of the lower extremities revealed fresh and chronic mixed-vein thrombosis (FCMVTs) presenting the "Blowfish sign," accompanied by pulmonary embolism. FCMVTs presenting the "Blowfish sign" may increase the risk of fatal pulmonary embolism, and its detection by ultrasonography is important for preventing pulmonary embolism.

OBJECTIVES: To compare the efficacy and safety of percutaneous microwave ablation (PMWA) and transcervical resection of myoma (TCRM) for submucosal fibroids. METHODS: From January 2019 to January 2021, we conducted a randomized controlled study involving patients with symptomatic uterine submucosal fibroids. Questionnaires were also used to measure the uterine fibroid symptom (UFS) scores and quality of life (QoL) scores before and after treatment at 3, 6, and 12 months...

INTRODUCTION: Fetal growth restriction (FGR) fetuses develop cardiovascular remodeling and dysfunction and, in this process, heart first compensates by changing its shape from ellipsoid to spherical and then cardiac dysfunction follows. Our aim was to evaluate global sphericity index (GSI) after 32 weeks of gestation to evaluate this change in cardiac shape and correlate GSI changes associated with fetal growth abnormalities. MATERIALS AND METHODS: This was a prospective study conducted at 32-38 weeks of gestation...

PURPOSE: The purpose of this study was to determine the feasibility of early Superb microvascular imaging (SMI) for prediction of the effect of HCC treatment after transcatheter arterial chemoembolization (TACE). MATERIALS AND METHODS: A total of 96 HCCs (70 patients) treated with TACE between September 2021 and May 2022 were included in this study. SMI, Color Doppler imaging (CDI), and Power Doppler imaging (PDI) were performed the day after TACE for evaluation of intratumoral vascularity of the lesion using an Aplio500 ultrasound scanner (Toshiba Medical Systems, Corporation, Tochigi, Japan)...

OBJECTIVES: To describe the incidence and diagnostic performance of ultrasound for perianal abscess or fistula-in-ano in pediatric patients with perianal inflammation. METHODS: We included 45 patients with perianal inflammation who underwent ultrasonography. To demonstrate the diagnostic performance of ultrasound for fistula-in-ano, a definite diagnosis of perianal abscess, and fistula-in-ano was determined as that proven through magnetic resonance imaging (MRI) or computed tomography (CT)...

OBJECTIVE: Coronary heart disease (CHD) is a disorder resulting from organic and functional coronary artery stenosis (CAS), thus causing reduced oxygenated blood in the heart. miRNAs are useful biomarkers in the diagnosis of atherosclerosis, CHD, and acute coronary syndrome. Vascular endothelial growth factor (VEGF) is closely related to CHD. This study explored the correlation of miR-296 and VEGF-B expression levels in peripheral blood with CAS degree in CHD patients. METHODS: Totally 220 CHD patients were enrolled and classified into mild-(71 cases)/moderate-(81 cases)/severe-CAS (68 cases) groups, with another 80 healthy cases as controls...

INTRODUCTION: Systemic amyloidosis is an uncommon disorder in which amyloid fibrils deposit extracellularly. Three-dimensional speckle-tracking echocardiography (3DSTE) is a novel method able to assess left ventricular (LV) global longitudinal strain (GLS). Our aim was to evaluate the prognostic impact of 3DSTE-derived LV-GLS in patients with cardiac amyloidosis (CA). MATERIALS AND METHODS: A total of 35 patients suffering from light-chain (AL) CA or transthyretin (TTR) CA were selected, but 7 patients had to be excluded due to insufficient image quality or were lost for follow-up...

Aorto-pulmonary venous fistula combined with pulmonary arteriovenous fistula is a rare condition with an unknown incidence.

To obtain the distribution characteristics of the different types (I-IV) and the role of ultrasound in the evaluation of infants with DDH (type IIc and above) receiving conservative treatment. METHODS: A retrospective analysis was performed. The chi-square test was used for comparisons between count-data groups. Two-sided tests were used for all analyses...

BACKGROUND: The diagnosis of intrathoracic and abdominal masses is challenging when lesions are located behind major vessels. Endoscopic ultrasound (EUS) or endobronchial ultrasound (EBUS)-guided transvascular needle aspiration (TVNA) provides a potentially useful diagnostic tool for such lesions. Data with respect to the safety and outcome of E-TVNA are scarce. Hence, this meta-analysis was conducted to assess the critical role of E-TVNA for diagnosis of various lesions. METHODS AND MATERIAL: A meta-analysis was performed by pooling the data from studies obtained from comprehensive search of Medline, Embase, and Scopus from January 2000 to September 2022...

PURPOSE: To evaluate subclinical LV systolic dysfunction in aKD patients by hematological indices, global layer-specific LV longitudinal strain and myocardial work (MW). METHODS: Forty-three normal controls and 42 aKD patients were enrolled in the present study. The peak systolic epimyocardial (GLSEpi), middle layer (GLSMid) and endomyocardial (GLSEndo) longitudinal strain, global myocardial work index (GWI), global constructive work (GCW), global wasted work (GWW) and myocardial work efficiency (GWE) were measured by two-dimensional speckle-tracking echocardiography in apical three-chamber, four-chamber, and two-chamber views...
