Blunt chest trauma can cause a variety of cardiac injuries, either immediately or days after the trauma. We report a case of traumatic ventricular septal defect and ribbonlike left ventricular aneurysm, which was diagnosed 15 years after the initial blunt chest trauma. It was successfully repaired using the endoventricular patch technique with a satisfactory 1-year follow-up result.

BACKGROUND:Coronary artery-to-pulmonary artery fistula is a rare disorder characterized by abnormal vascular communication between the coronary artery and pulmonary artery. While most patients remain asymptomatic, some might exhibit symptoms of myocardial ischemia, congestive heart failure, or even sudden cardiac death if coronary aneurysm, thrombosis, infective carditis, or other congenital cardiac defects coexist. Case presentation We present a 66-year-old male complaining of angina pectoris with a history of hypertension and active smoking. He was diagnosed with a coronary aneurysm based on coronary computed tomography angiography. We subsequently identified a coronary artery-to-pulmonary artery fistula with giant aneurysmal dilation on coronary angiography. Ultimately we conducted surgery ligation and aneurysmorrhaphy. During surgery, we discovered newly formed thrombus within the aneurysmal cavity. Histological analysis of the aneurysmal wall supported the diagnosis of the congenital disorder. Our patient was successfully discharged and remained asymptomatic at two months of follow-up.CONCLUSION:We presented a rare and complex combination of congenital coronary artery-to pulmonary artery fistula, giant coronary aneurysmal dilatation, and thrombosis through multi-modality evaluations.

BACKGROUND:Coronary artery disease (CAD) is the most common cause of heart failure (HF), and impaired ejection fraction (EF<50%) is a crucial precursor to HF. Coronary artery bypass grafting (CABG) is an effective surgical solution to CAD-related HF. In light of the high risk of cardiac surgery, appropriate scores for groups of patients are of great importance. We aimed to establish a novel score to predict in-hospital mortality for impaired EF patients undergoing CABG.METHODS:Clinical information of 1,976 consecutive CABG patients with EF<50% was collected from January 2012 to December 2017. A novel system was developed using the logistic regression model to predict in-hospital mortality among patients with EF<50% who were to undergo CABG. The scoring system was named PGLANCE, which is short for seven identified risk factors, including previous cardiac surgery, gender, load of surgery, aortic surgery, NYHA stage, creatinine, and EF. AUC statistic was used to test discrimination of the model, and the calibration of this model was assessed by the Hosmer-lemeshow (HL) statistic. We also evaluated the applicability of PGLANCE to predict in-hospital mortality by comparing the 95% CI of expected mortality to the observed one. Results were compared with the European Risk System in Cardiac Operations (EuroSCORE), EuroSCORE II, and Sino System for Coronary Operative Risk Evaluation (SinoSCORE).RESULTS:By comparing with EuroSCORE, EuroSCORE II and SinoSCORE, PGLANCE was well calibrated (HL P = 0.311) and demonstrated powerful discrimination (AUC=0.846) in prediction of in-hospital mortality among impaired EF CABG patients. Furthermore, the 95% CI of mortality estimated by PGLANCE was closest to the observed value.CONCLUSION:PGLANCE is better with predicting in-hospital mortality than EuroSCORE, EuroSCORE II, and SinoSCORE for Chinese impaired EF CABG patients.

OBJECTIVES:Pulmonary artery sarcoma (PAS) is a rare and devastating disease. The diagnosis modality and optimal surgical strategy remain unclear. The aim of this study was to report our surgical experience in this disease.METHODS:Between 2000 and 2017, 13 patients underwent operations for PAS at our institution. Five patients underwent tumour resection alone, whereas the other 8 patients received pulmonary endarterectomy. The medical records were retrospectively reviewed to evaluate the clinical characteristics, operative findings and the postoperative outcomes.RESULTS:There were 2 perioperative deaths, both had unresolved severe pulmonary hypertension. Follow-up was completed for all patients with a mean duration of 14.3 months (1-48 months). During follow-up, 6 patients died after a mean survival time of 20.2 months (4-48 months). For the 5 patients alive at follow-up (mean duration of 7.2 months), 3 already had local recurrence. For all 13 patients, the cumulative survival rates at 1, 2 and 3 years were 56.4, 37.6 and 18.8%, respectively. The 8 patients treated with pulmonary endarterectomy seemed to have a better survival rate compared with the remaining 5 patients without endarterectomy, although the difference was not statistically significant.CONCLUSIONS:Primary PAS is often mistaken for chronic pulmonary thromboembolism. Surgical intervention is the mainstay of treatment for PAS, but the prognosis after surgery remains poor. Compared to isolated tumour resection, pulmonary endarterectomy seemed to yield a better survival rate.

OBJECTIVES:This study reviews 9 patients with aortico-left ventricular tunnel (ALVT) and aims to establish the optimal surgical strategies for this exceptional and rare pathology.METHODS:54,882 patients underwent open-heart surgery at the Fuwai Hospital between July 1996 and May 2008. Nine of these patients were diagnosed with ALVT. One patient died of acute heart failure before operation. The remaining 8 patients underwent operation. The mean age of these 8 patients was 22.5 years. Clinical, echocardiographic and surgical details were reviewed.RESULTS:At operation the diagnosis was confirmed, and then repaired by direct suture closure (n = 1), single patch closure of the aortic end of the ALVT (n = 4), or aortic valve replacement (n = 3). In 5 patients, the aortic opening of the tunnel was above the right coronary sinus of Valsalva while in the other 3 it was above the left coronary sinus. All patients recovered safely. There was 1 late death (from perivalvular leak). The remaining patients remain asymptomatic at a mean follow up of 30.1 months.CONCLUSIONS:ALVT is a rare cardiac entity that should be treated soon after the diagnosis is made. The specific surgical operation should be individualized based on unique cardiac anomaly of each patient.
