Abstract Objective: Transthoracic echocardiography (TTE) is generally recognized as the top choice for detecting myocardial and cardiac cavity lesions. Sonographers mostly focus on myocardial, cardiac cavity and cardiac hemodynamics, whereas the abnormal extra-cardiac lesions are always unrecognized. The aim of this study was to investigate the ultrasonic image features in abnormal extra-cardiac lesions and the value of TTE in the detection of extra-cardiac lesions.Methods: 49 cases of abnormal extra-cardiac lesion detected by TTE from January 2014 to December 2019 were collected, which were confirmed by pathology. The two-dimensional ultrasonic characteristics and the relationships with the cardiac and great vessels were summarized on the basis of multi-view by TTE. All patients were also performed by computed tomography (CT). Results: In 49 patients with abnormal extra-cardiac lesions, 37 malignant cases and 12 benign cases were included. There were 41 cases (41/49,86.67%) of mediastinal lesions and 8 cases (8/49,16.33% ) of lung lesions. The maximum diameter ranged from 3.2cm to 13.66cm, and the median diameter was about 7.4cm, among which 29 cases (29/49,59.18%) were larger than 5cm. 4 cases (4/49, 4.08%) of cystic anechoic lesions were pericardial cyst. 2 cases (2/49, 4.08%) of cystic-solid echogenic lesions were teratoma. The remaining 45 cases (45/49, 91.84%) presented as solid hypoechoic or heterogeneous masses. 6 cases compressed the heart and 21 cases encroached on the heart and vessels. Diagnosis coincidence rates of TTE and CT were respectively 77.55% and 93.88%, with a statistical difference (p =0.012).Conclusion: Although the diagnostic coincidence rate of TTE is slightly lower than that of CT, TTE has certain diagnostic value for extra-cardiac lesions.

Abstract There are few studies on the early hemorrhagic transformation of ischemic stroke in plateau area. This study aimed to analyze the value of one-stop CT in predicting HT and functional outcomes in patients with acute ischemic stroke (AIS) caused by occlusion of great vessels before treatment in the high plateau region. Data were obtained from patients who underwent non-enhanced CT (NCCT), CTP and CTA examination within 24 hours from October 2019 to December 2020. Follow-up CT/MRI was performed within one month to determine if HT occurred later. The clinical data, laboratory results and imaging data of patients with and without HT were compared. Of the 74 patients included, 32(43.3%) had HT during follow-up, and HT was more likely to occur in poor collateral circulation (p = 0.029). The values of MTT, Tmax, PS, rCBV, rMTT, rPS in HT group were higher than those in non-HT group (p < 0.05). The results showed that PS > 1.315 ml/100 g/min (AUC, 0.753, p = 0.001) and rCBV > 1.470(AUC, 0.764; p=0.001) had better diagnostic value for HT. One-stop CT examination was performed before treatment in patients with AIS. Quantitative perfusion parameters and multi-phase CTA were used to evaluate the prognosis of HT after recanalization of proximal great vessels.

AbstractPulmonary atresia with abnormal ventriculoarterial connections in the presence of an intact ventricular septum is rare even in postnatal life. Two cases are described in which this combination of lesions was diagnosed in previable fetuses at autopsy. Both pregnancies were terminated for gross structural abnormalities discovered on antenatal ultrasound scans. In the first case, the pulmonary atresia was associated with intact ventricular septum, a double outlet left ventricle and hypoplasia of the tricuspid valve, right ventricle and arterial duct, a combination of lesions that would appear to be unique. In the second case, there was complete transposition and a hypoplastic left ventricle. The severity of the cardiac lesions in both fetuses was such that it is unlikely that either would have survived to term. In the first case no other malformation was present, but in the second there was also a large encephalocoele secondary to early amnion rupture, and a single umbilical artery. The association of the cardiac lesion with early amnion rupture in this second fetus would appear to be a chance event.

Background: Bidirectional cavopulmonary shunt (BCPS) is used for the interim palliation of a variety of cyanotic cardiac lesions. It is a standard palliative step for patients with functionally univentricular hearts in hope of achieving Fontan completion. At our center, first case of BCPS was performed on February 7, 2002. Here, we share our experience with BCPS over last 18 years. Methods: This is a retrospective analysis of all patients undergoing BCPS from February 2002 to July 2019. Patients who underwent BCPS as a part of one-and-half ventricular repair for Ebstein’s anomaly were excluded. Baseline, intraoperative, and postoperative variables were collected from hospital records. Results: A total of 326 patients with mean age of 5.7±5.8 years (median 3.5 years; range: 1.5 months-32 years) underwent BCPS over last 18 years. Majority (61%) were males. Double outlet right ventricle (DORV) was the most common primary cardiac lesion (30%) followed by tricuspid atresia (23%). Mean ICU stay was 3.9±4.8 days, with hospital stay of 7.8±5.9 days. In-hospital mortality was 15%. Patients who died had low body weight (11.8±10.7 kg vs 16.0±11.6 kg; p=0.019), and longer cardiopulmonary bypass time (101±64 min vs 76±42 min; p=0.001). Oxygen saturation improved significantly at the time of discharge (79.2±9.5% vs 68.6±13.7%; p=0.000). Conclusion: This is the first report of its kind to analyze the outcomes of BCPS in our center. We have discussed the evolution of BCPS surgery in our center and presented our outcomes. Our in-hospital mortality remains high, and we need to strive towards reducing the mortality.
