OBJECTIVES: Type 2 diabetes (T2DM) is a common comorbidity in patients with degenerative aortic stenosis (AS).As a key item of the American Society of Thoracic Surgeons (STS) score, it has a vital impact on the clinical prognosis of traditional thoracic surgery. T2DM has an adverse effect on the morbidity and mortality of cardiovascular diseases. At the same time, studies have shown that T2DM are associated with myocardial hypertrophy and remodeling, decreased left ventricular function, and worsening heart failure symptoms in the AS patients. Transcatheter aortic valve replacement (TAVR) as an interventional method to replace the aortic valve has better safety for middle and high risk patients in surgery, but the impact of T2DM on the clinical outcome of TAVR in AS patients is not clear.By analyzing the clinical and image characteristics of patients with AS and T2DM who received TAVR treatment, so as to explore the effect of T2DM on the perioperative complications and prognosis of TAVR. METHODS: A total of 100 consecutive patients with severe AS, who underwent TAVR treatment and were followed up for more than 1 month, were selectedin the Second Xiangya Hospital of Central South University from January 2016 to December 2020.Among them, 5 patients who were treated with TAVR due to simple severe aortic regurgitation were not included, therefore a total of 95 patients with severe aortic stenosis were enrolled in this study.The age of the patients was (72.7±4.8) years old, and there were 58 males (61.1%), and the patients with moderate or above aortic regurgitation had 30 cases (31.6%). The patients were divided into a diabetic group and a non-diabetic group according to whether they were combined with T2DM.There was no statistical difference in age, gender, body mass index (BMI), STS score, and New York Heart Association (NYHA) cardiac function classification between the 2 groups (all P>0.05). The primary end point was defined as a composite event consisting of all-cause death and stroke one month after surgery, and the secondary end point was defined as TAVR-related complications immediately after surgery and one month after surgery.The preoperative clinical data, cardiac ultrasound data, CT data, postoperative medication and the incidence of each endpoint event were compared between the 2 groups.The predictive model of adverse events was constructed by single factor and multivariate logistic regression. RESULTS: Compared with the non-diabetic group, the diabetic group had high blood pressure and chronic renal insufficiency.There was no significant difference in preoperative ultrasound echocardiography between the 2 groups. Preoperative CT evaluation found that the anatomical structure of the aortic root in the diabetic group was smaller than that in the non-diabetic group, and there was no significant difference in the incidence of bicuspid aortic valve between the 2 groups (all P<0.05). In terms of postoperative medication, the use of statins in the diabetes group was significantly higher than that in the non-diabetic group. In the diabetes group, 6 patients (37.5%) received insulin therapy, and 9 patients (56.3%) received oral medication alone.Univariate logistic regression analysis showed that the all-cause death and stroke compound events was increased in the diabetes group in 30 days after TAVR (OR=6.86; 95% CI: 2.14 to 21.79; P<0.01). Heart disease (OR=2.80; 95% CI: 0.99 to 7.88; P<0.05) and chronic renal insufficiency (OR=3.75; 95% CI: 1.24 to 11.34; P<0.05) were also risk factors for all-cause death and stroke compound events.In a multivariate analysis, after adjusting for age, gender, BMI, comorbidities, N-terminal pro-B type natriuretic peptide (NT-proBNP), total calcification score, ejection fraction, and degree of aortic regurgitation, T2DM was still a risk factor for all-cause death and stroke compound events in 30 days after TAVR (OR=12.68; 95% CI: 1.76 to 91.41; P<0.05). CONCLUSIONS T2DM is a risk factor for short-term poor prognosis in patients with symptomatic severe AS after TAVR treatment. T2DM should play an important role in the future construction of the TAVR surgical risk assessment system, but the conclusions still need to be further verified by long-term follow-up of large-scale clinical studies.

Objective: To identify the characteristics including clinical features and pulmonary computed tomography (CT) features of heart failure and novel coronavirus pneumonia(COVID-19). Methods: This study was a retrospective study. A total of 7 patients with Heart failure and 12 patients with COVID-19 in the Second Xiangya Hospital of Central South University between December 1, 2019 and February 15, 2020 were enrolled. The baseline clinical and imaging features of the two groups were statistically analyzed. Results: There was no significant difference in age and sex between the two groups, but the incidence of epidemiological contact history, fever or respiratory symptoms in the COVID-19 group was significantly higher than that in the heart failure group (12/12 vs. 2/7, P=0.001; 12/12 vs. 4/7, P<0.001). While the proportion of cardiovascular diseases and impaired cardiac function was significantly less than that of the heart failure group(2/12 vs.7/7, P<0.001; 0/12 vs.7/7, P<0.001). For imaging features, both groups had ground-glass opacity and thickening of interlobular septum, but the ratio of central and gradient distribution was higher in patients with heart failure than that in patients with COVID-19 (4/7 vs. 1/12, P=0.04). In heart failure group, the ratio of the expansion of small pulmonary veins was also higher (3/7 vs. 0, P=0.013), and the lung lesions can be significantly improved after effective anti-heart failure treatment. Besides, there are more disease with rounded morphology in COVID-19 (9/12 vs. 2/7, P=0.048) . Conclusions More patients with COVID-19 have epidemiological history and fever or respiratory symptoms. There are significant differences in chest CT features, such as enlargement of pulmonary veins, lesions distribution and morphology between heart failure and COVID-19.

Unroofed coronary sinus syndrome (UCSS), also named coronary sinus septal defect, is a rare type of atrial septal defect with the incidence less than 1% of the total number of atrial septal defects. It is caused by incomplete formation of left atrial venous folds during embryonic development. Here we reported a patient with UCSS, who was treated in the Second Xiangya Hospital of Central South University. The patient was 50 years old and the main clinical manifestations were fatigue and shortness of breath after repeated exercise. Color Doppler echocardiography showed coronary sinus dilatation (17 mm×14 mm), indicating the possibility of permanent left superior vena cava. Pulmonary angiography showed that the left ventricle and coronary sinus were developed at the same time while the atrial septum was intact after the development of the left atrium, followed by the right atrium and right ventricle, indicating a partial anomalous pulmonary venous drainage (intracardiac type). Finally, the cardiac computed tomograhic angiography showed that 4 pulmonary veins and permanent left superior vena cava (PLSVC) went into the left atrium and the coronary sinus, respectively, while the coronary sinus septum was absent and the PLSVC was connected with the left atrium. The patient was later treated with the correction of non-parietal sinus syndrome in the Cardiovascular Surgery Department of our hospital.

Objective: To assess the clinical characteristics and identify the risk factors in the acute myocardial infarction (AMI) patients complicating with ventricular septal rupture (VSR). Methods: A retrospective study was performed on 96 AMI patients complicating with VSR, who were hospitalized in the Second Xiangya Hospital of Central South University, Hunan Provincial Peoples′ Hospital, the First Affiliated Hospital of University of South China, the Second Affiliated hospital of University of south China, Xiangtan Central Hospital from December 2007 to May 2017. There were 46 females and the age was (66.2±10.7) years (from 43 to 90 years). Patients were divided into in-hospital survival group (n=64) and in-hospital death group (n=32). The 96 patients were also divided into the early death group (survived ≤2 weeks after admission, n=50) and non-early death group (survived>2 weeks after admission, n=46). Multivariate logistic regression was used to analyze the independent risk factors of the early death. Results: Location of VSR was available in 71 patients, VSR was located at the apical or anterior septum near the apical region in 64.0% (32/50) patients with the anterior AMI, VSR was located at the posterior wall and basal inferior segment in 57.1% (12/21) patients with non-anterior AMI. Compared to the in-hospital survival group, patients in the in-hospital death group were older ((69.6±11.3) years vs. (64.6±10.1) years, P=0.031), incidence of non-ventricular aneurysm (71.9% (23/32) vs. 37.5% (24/64), P=0.001) and anterior AMI (84.4%(27/32) vs. 62.5%(40/64), P=0.028) was significantly higher in the in-hospital death group than in the in-hospital survival group. The comparison between the early death group and non-early death group showed that older age, female, no history of angina or myocardial infarction, Killip grade>Ⅲ, and non-ventricular aneurysm were related to increased risk of the early mortality in this patient cohort. Logistic regression analysis revealed that female (OR=5.109,95%CI 1.19-22.00, P=0.012), no history of angina or myocardial infarction (OR=23.34, 95%CI 3.44-158.37, P=0.001), Killip grade>Ⅲ(OR=5.35, 95%CI 1.26-22.66, P=0.019) and non-ventricular aneurysm (OR=6.30,95%CI 1.67-23.73, P=0.005) were independent risk factors for early death in this patient cohort. Conclusion The risk factors of in-hospital death include older age, non-ventricular aneurysm and anterior AMI. Female, no history of angina or myocardial infarction, Killip grade>Ⅲ and non-ventricular aneurysm are independent risk factors for the early death of AMI patients complicating VSR.

OBJECTIVE: To explore the cause of cardiac perforation and tamponade during cardiac catheterization and intervention and to evaluate the effectiveness of the emergency treatment for tamponade in our hospital. METHODS: The clinical data from 23, 319 patients who received diagnostic catheterization or therapeutic procedures were analyzed retrospectively. RESULTS: Cardiac perforation and cardiac tamponade were observed in 22 of the 23, 319 patients during catheter procedures. It includes 1 in coronary artery angiography, 9 in percutaneous balloon mitral valvuloplasty, 3 in diagnosis, 2 in congenital heart disease intervention, 2 in pacemaker implantation, 2 in atrial fibrillation ablation and the other 3 in coronary revascularization. The occurrence of cardiac perforation in 11 patients was related to puncture of the interatrial septum and/or the procedure in the left atrial procedure and 2 were related to high pressure injection. Seventeen patients were found cardiac tamponade in the process of catheterization, and 5 were found at 2-14 h after operation. Pericardiocentesis and pericardial catheter drainage were performed in 20 patients and 11 of them succeeded. Among the other 11 patients, 7 were successfully saved by thoracotomy and 4 died. CONCLUSION Cardiac tamponade is a severe and fatal complication that may occur in different catheter procedures. Early prevention and diagnosis and performingperi cardiocentesis and drainage timely are critical to reduce the mortality.

OBJECTIVE: To retrospectively evaluate the efficacy of stent-delayed implantation in patients with acute myocardial infarction (AMI) with high thrombus burden after thrombus extraction was performed. METHODS: Of 186 consecutive AMI patients, 56 were included according to thrombus score(TS)>or=2, and then were divided into 2 groups based on the thrombus score after thrombus extraction was executed: the stent-direct implantation group (TS=0 or 1)and the stent-delayed implantation group (TS>or=2) even if 3 times thrombus extraction were given. Thrombolysis in myocardial infarction(TIMI)flow grade and TIMI myocardial perfusion (TMP) were used to assess the coronary artery flow and myocardial perfusion,respectively. RESULTS: TIMI score in the stent-direct implantation group was lower than that in the stent-delayed implantation group. There was no significant difference(P=0.07). TMP score in the stent-direct implantation group was significantly lower than that in the stent-delayed implantation group (P<0.05). CONCLUSION Stent-delayed implantation can remarkably improve myocardial perfusion in AMI patients with high thrombus burden after thrombus extraction and intensive anti-thrombosis therapy is administrated.

Objective To demonstrate the effect on platelet aggregation rate (PAR) and clinical outcomes of tirofiban in patients undergoing emergency percutaneous coronary intervention (PCI) and to evaluate its safety. Methods Thirty patients presenting with STEMI and had received emergency PCI were enrolled into the tirofiban group. By means of matching, another 30 patients who received elective PCI during the same period from September 2005 to March 2006 were enrolled as the control in the 2nd Xiangya Hospital of Central South University. Patients in the tirofiban group received tirofiban infused at 10 ?g/kg within 3 minutes as bolus 10-30 minutes pre-operation followed by infusion at 0.15 ?g/(kg?min) for 36 hours. The control group received the same dosage of placebo. All patients received intravenous heparin and oral ADP receptor antagonist and aspirin. PAR, incidence of 7 and 30 days composite end point events (death, persistent myocardial ischemic, reinfarction and target vessel revascularization) and bleeding complications were observed in both groups. Results Compared with the control group, the tirofiban group showed a decrease in PAR (19?8)% vs (54?7)%, P
