LETTER
Yan Sun, Hui Ming Zhang, Hao Wang
A rare case of mechanical prosthetic valve dysfunction in mitral position. The mechanical valve opened once every two cardiac cycles. We also found the opening time of the mechanical valve in aortic positions was long and short alternately because of the Left ventricular volume changed every cardiac cycles.

Cardiovascular complications induced by adjuvant cancer therapies may become symptomatic after many years, being responsible for increased morbidity and mortality in long-term survivors. We report a case of a 54-year old female admitted for severe heart failure induced by myocardial and valvular damage after postoperative adjuvant therapy for left breast cancer 6 years ago. Her recent history revealed nonST elevation myocardial infarction in the absence of significant cardiovascular risk factors. Transthoracic echocardiography, tissue Doppler imaging and speckle-tracking imaging revealed severe biventricular systolic dysfunction, severe mitral and tricuspid regurgitation and severe pulmonary hypertension...

Peliosis hepatis is a rare benign disorder of the liver, histologically characterized by blood-filled cystic cavities of various sizes and irregular shapes, communicating with the hepatic sinusoids. Only a few cases of peliosis hepatis have been described using contrast enhanced ultrasound showing admittedly various dynamic enhancement patterns. We present a case of peliosis hepatis with a typical target-sign enhancement depicted by means of contrast enhanced ultrasound.

We present a large hydatid cyst located midline and posterior to prostatic gland and seminal vesicles in an asymptomatic patient. Computed tomography (CT) scan revealed a large retrovesical mass and the transrectal ultrasonography idetified a degenerated hydatid cyst with "ball of wool'' appearance. Although extremely rare, hydatid disease should be kept in mind in the differential diagnosis of pelvic particularly retrovesical midline masses.

In recent years, fetal echocardiography has been used for the screening and diagnosis of anatomical heart defects and for the detailed study of fetal cardiac function. This method is characterized by its easy implementation and good reproducibility, allowing the diagnosis of myocardial dysfunction even in its subclinical phase. The functional assessment of the fetal heart should be routinely performed in fetuses with congenital heart disease and those without anatomical malformation. Several extra-cardiac conditions may alter fetal cardiac function, by increased placental resistance, volume overload or hyperdynamic circulation, compression, or maternal systemic disease with involvement of the fetal myocardium...

Accurate differentiation of focal thyroid nodules (FTL) and thyroid abnormalities is pivotal for proper diagnostic and therapeutic work-up. In these two part articles, the role of ultrasound techniques in the characterization of FTL and evaluation of diffuse thyroid diseases is described to expand on the recently published World Federation in Ultrasound and Medicine (WFUMB) thyroid elastography guidelines and review how this guideline fits into a complete thyroid ultrasound exam.

AIMS: Maternal red blood cell alloimmunization is an important cause of fetal morbidity and mortality in the perinatal period, despite well-organized prophylaxis programs. The objective of the study was to evaluate placental elasticity by using Acoustic Radiation Force Impulse (ARFI) in Rhesus (Rh) alloimmunized pregnant women with hydropic and nonhydropic fetuses and to compare those with healthy pregnant women. MATERIAL AND METHODS: This case-control and descriptive study comprised twenty-eight healthy pregnant women, 14 Rh alloimmunized pregnant women with nonhydropic fetuses, and 16 Rh alloimmunized pregnant women with hydropic fetuses in the third trimester of pregnancy...

AIM: The present study evaluated the effect of differences in the peak systolic velocity (PSV) and resistive index (RI) in the testicular artery (TA), capsular artery (CA), and intratesticular artery (ITA) after microscopic subinguinal varicocelectomy (MSV) on postoperative pain and semen parameters. PATIENTS AND METHODS: Scrotal color Doppler ultrasound (CDUS) measurements were made in 33 patients (age 18-31 years) prior to MSV and 3 and 6 months after MSV. Pain was recorded using a visual analog scale and sperm concentration was determined to analyze the predictive value of the CDUS parameters regarding surgical outcome...

prove the performance for staging common femoral vein thrombi (CFVT). MATERIAL AND METHODS: A total of 194 consecutive patients with CFVT who underwent US and 2D-SWE were enrolled. These patients were categorized into three groups according to CFVT duration: Stage A (≤14 days), Stage B (14 days to 6 months), and Stage C (≥6 months). The diagnostic performance was assessed by the area under the receiver operating characteristic curve (AUC). RESULTS: Among all US features, CFV diameter ratio of thrombosed leg to contralateral leg (CFVD_ratio) showed the highest AUC in predicting Stage A and Stage C (0...

"No reflow" phenomenon is a common complication with significant prognostic repercussions after reperfused acute myocardial infarction. Previous studies have shown the feasibility and prognostic significance of coronary microcirculation assessment by transthoracic Doppler of left anterior descending artery (LAD). The aim of the study was to evaluate the time course of the coronary microcirculation status after acute anterior myocardial infarction reperfused by primary angioplasty with stent on LAD. MATERIAL AND METHODS: Twenty-three patients underwent transthoracic echocardiography at 3 days (M0) and one month (M1) after reperfusion, with LAD flow analysis (peak systolic and diastolic velocities, diastolic deceleration time and systolic flow reversal)...

AIMS: Our aim was to evaluate the elasticity features of the optic nerve using strain (SE) and shear wave elastography (SWE) in multiple sclerosis (MS) patients in comparison with healthy subjects. MATERIAL AND METHODS: One hundred and seven optic nerves from 54 MS patients and 118 optic nerves from 59 healthy subjects were examined prospectively by SE and SWE. Optic nerves were divided into three types in accordance to the elasticity designs, as follows: type 1 predominantly blue (hardest tissue); type 2 predominantly blue/green (hard tissue); and type 3 predominantly green (intermediate tissue)...

AIM: The purpose of the study was to assess the effect of Acoustic Radiation Force Impulse (ARFI) elastography in the diagnosis of liver fibrosis in chronic hepatitis B and C patients through Meta-analysis. MATERIAL AND METHODS: Four databases (PubMed, the Cochrane Library, WanFang data, and CNKI) were searched. The key words were: ("ARFI" or "acoustic radiation force impulse") combined with "liver fibrosis" and ("chronic hepatitis" or "HBV HCV"). Heterogeneity (I2) was assessed, and its source was analyzed through meta-regression...
