@#Objective To describe the effect of sequential pulmonary balloon angioplasty for patients with chronic thromboembolic pulmonary hypertension, who was accompanied with progressed pulmonary hypertension after pulmonary endarterectomy surgeries. Methods From 2014 to December 2017, 7 patients were treated with a combination therapy of pulmonary endarterectomy and sequential pulmonary balloon angioplasty. There were 1 male and 6 females at age of 58 (43–59) years. A follow-up period of more than 1 year was accomplished. The result of right sided heart catheterization and ultrasonic cardiogram between and after the pulmonary endarterectomy or balloon angioplasty was collected. Results Seven patients were treated with a combination of pulmonary endarterectomy and sequential pulmonary balloon angioplasty, which included 1 patient of single pulmonary balloon angioplasty and 6 patients of multiple pulmonary balloon angioplasties. The balloon dilation times was 2 (2–6), and the number of segments during each single balloon dilatation was 3–5, compared with the first clinical results before the first balloon dilation, systolic pulmonary artery pressure [53 (47–75) mm Hg vs. 45 (40–54) mm Hg, P=0.042), mean pulmonaryartery pressure [38 (29–47) mm Hg vs. 29 (25–39) mm Hg, P=0.043], N terminal-B type natriuretic peptide [1 872 (1 598–2 898) pg/ml vs. 164 (72–334) pg/ml, P=0.018] improved significantly after the last balloon angioplasty. Heart function classification (NYHA) of all the 7 patients were recovered to Ⅰ-Ⅱclasses (P<0.05). Conclusion Sequential pulmonary balloon angioplasty after pulmonary endarterectomy can further reduce the patient's right heart after load, improve the heart function for patients with progressed pulmonary hypertension after pulmonary endarterectomy surgeries.

@#Objective To evaluate the long-term clinical effect and risk factors of tricuspid valve replacement (TVR) as a relief treatment for adult patients with congenitally corrected transposition of the great artery (CCTGA). Method We retrospectively analyzed the clinical data of 47 adult patients with CCTGA who underwent tricuspid valve replacement in Fuwai Hospital between 2000 and 2017 year. There were 27 males and 20 females with operation age of 14–62 (38.8±13.5) years. Preoperative echocardiography showed moderate or more tricuspid regurgitation in all patients. The basic data of patients before and during operation were recorded. Survival was followed up by telephone and ultrasound report. Results The average follow-up time was 6.5±3.7 years. The 1-year, 5-year and 10-year survival rate or the incidence of heart transplant-free was 94.6%, 90.5% and 61.7%, respectively. During the follow-up period, the long-term right ventricular ejection fraction of most patients (>90%) was still greater than or equal to 40%. Increased preoperative right ventricular end diastolic diameter (RVEDD) was a risk factor for death or heart transplantation (risk ratio 1∶11, P=0.04). The survival rate of patients with RVEDD (>60 mm) before operation was significantly reduced (P=0.032). Conclusion TVP is a feasible treatment for adult patients with CCTGA. The increase of preoperative RVEDD is a risk factor for long-term mortality.

@#Objective To explore our novel strategy of surgical treatment for ventricular septal rupture (VSR) and the long-term outcomes. Methods All the patients referred to the Center of Adult Surgery, Fuwai Hospital were treated with integration treatment of vasoactive agents, intra-aortic balloon pump, or left ventricular assist device. The timing of surgical treatment was individually customized. One hundred and five consecutive patients with VSR (63 males, 42 females ) presented at the mean age of 63 (range, 41 to 80) years. We retrospectively analyzed the results and followed up patients who survived the surgical procedure. Results They were divided into a hemodynamics stable group (25 patients, 2 received emergent operation and 23 received selective operation) and a hemodynamics unstable group (80 patients, 34 received vasoactive agents and selective operation, 4 received vasoactive agents and emergent operation, 20 received vasoactive agent, intra-aortic balloon counterpulsation (IABP), and selective operation, 16 received vasoactive agents, IABP, and emergent operation, 2 received vasoactive agents, IABP, ventilator support, and selective operation, 2 received vasoactive agents, IABP, and ventilator support and emergent operation, 2 received vasoactive agents, ventilator support, and selective operation). There were 3 in-hospital deaths. Ninety-nine patients were followed up, with a follow-up rate of 97.1%. The mean follow-up time was 76.56±47.78 months. There were 2 late deaths during follow-up. Conclusion The timing of surgical treatment for ventricular septal rupture should be individually customized. The long-term outcomes of ventricular septal rupture patients who survived the surgery are satisfactory.

@#Objective To analyze the risk factors of new-onset postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG). Methods From September 2011 to October 2013, 1 614 consecutive patients underwent elective coronary artery bypass grafting in Fuwai Hospital. There were 1 281 males and 333 females at average age of 60.3±8.4 years. Holter data recorded for 5 days after operation were collected and analyzed. The risk factors associated with POAF were assessed according to the baseline and intraoperative data, and the positive variables were stratified. Results A total of 314 patients (19.5%) developed new-onset POAF. The rate of POAF was elevating with the increase of age (P<0.001). Conclusion Age was an independent risk factor for POAF in patients undergoing elective CABG alone.

@#Objective To evaluate the clinical and follow-up results of the surgical treatment for hypertrophic obstructive cardiomyopathy associated with aortic stenosis. Methods We retrospectively analyzed the clinical data of the patients with hypertrophic obstructive cardiomyopathy plus aortic stenosis in our hospital from February 2008 to October 2015. There were 4 males and 3 females aged 55.6 ± 7.5 years. All the patients were received concomitant aortic valvulopasty at the time of modified extended Morrow procedure. Echocardiographic data and major complications were recorded through the outpatient clinic and telephone. Results The postoperative ventricular septal thickness, left ventricular outflow tract gradient and aortic gradient were significantly lower than those in preoperation with statistical differences (P<0.05). During the mean follow-up 25.6 ± 28.2 months period, 1 patient died of cerebral hemorrhage, 1 patient was implanted a permanent pacemaker, and 1 patient had a postoperative new-onset atrial fibrillation. All patients had a satisfied prosthetic valve function and the left ventricular outflow tract gradient. The patient's symptoms and heart function significantly improved postoperatively. Conclusion For patients with hypertrophic obstructive cardiomyopathy associated with moderate to severe aortic stenosis, concomitant aortic valvulopasty at the time of modified extended Morrow procedure is an appropriate and effective treatment, which can significantly alleviate the clinical symptoms, and improve quality of life with a satisfied prognosis.

@#Objective To evaluate a score system to allow stratification of complexity in degenerative mitral valve repair. Methods We retrospectively reviewed the clinical data of 312 consecutive patients who underwent surgery for mitral valve repair and whose preoperative echocardiography was referable in our hospital from January 2012 to December 2013. A scoring system for surgical complexity was used based mainly on the preoperative echocardiography findings. Complexity of mitral valve repair was scored as 1 to 9, and patients were categorized into 3 groups based on the score for surgical complexity: a simple group (1 point), an intermediate group (2-4 points) and a complex group (≥5 points). There were 86 males and 35 females in the simple group (n=121) with an average age of 51.6±12.6 years, 105 males and 53 females in the intermediate group (n=158) with an average age of 51.1±12.8 years and 25 males and 8 females in the complex group (n=33) with an average age of 49.3±13.0 years. Results There was significant difference in surgical complexity in different groups. In the simple, intermediate and complex groups, the mean cardiopulmonary bypass time was 111.7±45.5 min, 117.7±40.4 min and 153.4±74.2 min (P<0.001), the mean cross-clamping time was 77.5±33.8 min, 83.2±29.9 min and 108.8±56.2 min (P<0.001), and the mean number of repair techniques utilized was 2.1±0.4, 2.4±0.6 and 2.8±0.8 (P<0.001). However, there was no significant difference in the early and late outcomes in different groups. Conclusion It is feasible to use echocardiography to quantitatively evaluate the difficulty of mitral valvuloplasty.
