Presented in this study were three cases of lung cancer undergoing pulmonary venoplasty. In the 3 patients with central type of carcinoma of lung involving pulmonary vein, the main branch of right superior pulmonary vein and the distal end of the superior-lobe vein were occluded. The root part of the vein of right-middle lobe, plus part of vessel of of right superior vein was resected. The right superior vein was reconstructed by continuous 6-0 Prolene sutures. After the operation, the reconstructed was patent and the surgical margin was tumor-free. Postoperatively, clinical manifestations and plain chest films did not show any signs of venous blockade. The patients were discharged healed 3 weeks after the operation. The technical details of the surgery were presented, the improvements on the basis of traditional methods were discussed and its clinical application was evaluated. It is concluded that pulmonary venoplasty is a safe and feasible operation. Further improvement of the surgery will help conserve more lung tissue and benefit more patients because of expanded indications.

OBJECTIVETo review the efficacy of total anomalous pulmonary venous connection (TAPVC) repair and to conclude the factors impacting the peri-operative death rate.

METHODSThe clinical data of 145 infants under 1 year old who underwent the TAPVC repair from January 2001 to July 2008 was analyzed. There were 94 male and 51 female patients. The mean age when the repair was performed was (7 ± 3) months, and the average weight was (6.3 ± 1.6) kg. As to the pulmonary connection type, 77 patients were supracardiac (53.1%), 47 patients were cardiac (32.4%), 9 patients were intracardiac (6.2%), and the remaining 12 patients were mixed (8.3%). Pre-surgery echocardiography showed that 21 patients had pulmonary venous obstruction (12 patients were supracardiac type, 3 patients were cardiac type, 3 patients were intracardiac type, and 3 patients were mixed type).

RESULTSAll patients underwent two-ventricle anatomy correction (the cases of complex malformations had been excluded). Peri-operative mortality was 11.7% (17/145). Because of the significant improvement in the surgical techniques, anesthesiology, cardiopulmonary bypass and the management of ICU in January 2006, the population was divided into two groups: A (before January 2006) and B (after January 2006). Peri-operative mortality decreased from 19.0% in group A to 6.2% in group B(P = 0.020). After analysis, it was determined that the factors impacting mortality were which group the patient belongs to, whether he/she had preoperative pulmonary vein obstruction and how big the atril septel connection was. The operative technique to keep the anastomotic aperture adequate and prophylaxis pulmonary hypertensive episodes contributed to the improvement on the mortality rate. There had been no case of repeating the surgery because of pulmonary venous obstruction during peri-operative care period.

CONCLUSIONSImprovements of the surgical technique as well as the treatment in preoperative and postoperative have led to the reduction of the mortality. Preoperative pulmonary vein obstruction is still an important factor that contributes to early mortality.

Pulsed electric field(PEF) provides high-energy instantaneous pulse and release energy to myocardial cell membrane, resulting in irreversible electroporation and causes myocardial cell contents leakage, destruction of intracellular homeostasis, cell death, and slight inflammatory response. PEF as non-thermal energy promotes the design and application of arrhythmia ablation catheter to enter a new stage. There are currently limited clinical studies that have proved the safety and effectieness of Farawave PEF catheter, PVAC GOLD PEF catheter, Lattice-tip Sphere-9 PEF and radiofrequency (RF) catheter used for atrial fibrillation ablation, but still need further discussion. The research of atrial fibrillation ablation with PEF is under study in China. In this paper, the design and application of PEF ablation for tachyarrhythmia are reviewed.

Recently, we treated a patient with pulmonary vein sarcoma. The patient was a 41-year-old woman, had cough, short of breath and apsychia, with obvious jugular venous distention, rales in both lungs and a diastolic murmur at the apex. CT and Echo revealed a tumor in the left atrium. She received an emergency surgery to remove the mass in the heart. The pathological diagnosis demonstrated it as leiomyosarcoma. Though the patient accepted radiotherapy and chemotherapy, she still died of recurrence and metastasis of the sarcoma 10 months after operation.

OBJECTIVES: To evaluate the clinical effectiveness of integrated management during the perinatal period for fetuses diagnosed with total anomalous pulmonary venous connection (TAPVC) by prenatal echocardiography. METHODS: Clinical data of 64 cases of TAPVC fetuses diagnosed by prenatal echocardiography and managed with integrated perinatal care in Qingdao Women and Children's Hospital from January 2017 to December 2021 were retrospectively analyzed. Integrated perinatal care included multidisciplinary collaboration among obstetrics, fetal medicine, ultrasound, pediatric cardiology, pediatric anesthesia, and neonatology. RESULTS: Among the 64 TAPVC fetuses, there were 29 cases of supracardiac type, 27 cases of intracardiac type, 2 cases of infracardiac type, and 6 cases of mixed type. Chromosomal analysis was performed in 42 cases, and no obvious abnormalities were found. Among the 64 TAPVC fetuses, 37 were induced labor, and 27 were followed up until term birth. Among the 27 TAPVC cases, 2 cases accepted palliative care, 2 cases were referred to another hospital for treatment and lost to follow-up, while the remaining 23 cases underwent primary repair surgery. One case died within 6 months after the operation due to low cardiac output syndrome, while the other 22 cases were followed up for (2.1±0.3) years with good outcomes (2 cases underwent a second surgery within 1 year after the first operation due to anastomotic stenosis or pulmonary vein stenosis). CONCLUSIONS TAPVC fetuses can achieve good outcomes with integrated management during the perinatal period.
