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.

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.

BACKGROUND: Pulmonary vein (PV) occlusion generally depends on repetitive contrast agent injection when cryoballoon ablation for atrial fibrillation (AF). The present study was to compare the effect of cryoballoon ablation for AF guided by transesophageal echocardiography (TEE) vs. contrast agent injection. METHODS: Eighty patients with paroxysmal AF (PAF) were enrolled in the study. About 40 patients underwent cryoballoon ablation without TEE (non-TEE group) and the other 40 underwent cryoballoon ablation with TEE for PV occlusion (TEE group). In the TEE group during the procedure, PVs were displayed in 3-dimensional images to guide the balloon to achieve PV occlusion. The patients were followed up at regularly scheduled visits every 2 months. RESULTS: No differences were identified between the groups in regard to the procedure time and cryoablation time for each PV. The fluoroscopy time (6.7 ± 4.2 min vs. 17.9 ± 5.9 min, P < 0.05) and the amount of contrast agent (3.0 ± 5.1 mL vs.18.1 ± 3.4 mL, P < 0.05) in the TEE group were both less than the non-TEE group. At a mean of 13.0 ± 3.3 mon follow-up, success rates were similar between the TEE group and non-TEE group (77.5% vs. 80.0%, P = 0.88). CONCLUSIONS Cryoballoon ablation with TEE for occlusion of the PV is both safe and effective. Less fluoroscopy time and a lower contrast agent load can be achieved with the help of TEE for PV occlusion during procedure.

OBJECTIVETo discuss the experience of surgical treatment of total anomalous pulmonary venous connection (TAPVC) in infants.

METHODSThe clinic data of 84 cases with TAPVC under 6 months of age underwent surgical treatment at Department of Cardiac Surgery, Guangzhou Women and Children's Medical Center from January 2012 to October 2015 were analyzed retrospectively. There were 58 male and 26 female patients. The patients were aged 1 days to 6 months with a mean of (2.4±2.2) months at surgery, including 22 newborns. Body weight was 1.8 to 6.8 kg with a mean of (4.3±1.2) kg. There were 24 cases of intracardiac type, 46 cases of supracardiac type, 10 cases of infracardiac type and 4 cases of mixed type. There were 26 cases received emergent operation. There were 14 cases used Sutureless technique in operations and 46 cases used conventional methods in the no-intracardiac type cases, and 2 cases enlarged the anastomsis with autologous pericardium. According to the condition, corrective surgeries of other anomalies were performed in the meantime, including 3 Warden operations (right side), 3 bilateral bidirectional Gleen operation, 2 correction of unroofed coronary sinus syndrome, 1 coarctation of aorta correction with deep hypothermic circulation arrest, and 1 repair of ventricular septal defect.

RESULTSThe ratio of newborn was higher in Sutureless technique group than in conventional methods group (7/14 vs. 32.6%, χ(2)=4.927, P=0.043), and mean age was less ((1.8±0.4) months vs. (2.4±2.2) months, F=4.257, P=0.042), but there were no difference in body weight, cardiopulmonary bypass time and aorta clamped time between the two groups. Followed up for 1 to 46 months, 10 cases (11.9%) died overall and the mortality of intracardiac (3/10) and mixed (2/4) type were much higher than in intracardiac (4.2%) and supracardiac (13.0%) type. The mortality were no difference between newborn and infants, or whether emergent operation, or Sutureless technique and conventional methods. The maximal pulmonary venous flow velocity was abnormal speed-up >1.8 m/s at 1 week and 1 to 3 months post-operation mostly.

CONCLUSIONSThe mortality of TAPVC was differed by different types. Intrinsic pulmonary vein stenosis maybe the main cause of mortality. The high quality of anastomsis could reduce the operative mortality.

Pulmonary vein (PV) stenosis is a complication of ablation therapy for arrhythmias. We report two cases with chronic lung parenchymal abnormalities showing no improvement and waxing and waning features, which were initially diagnosed as nonspecific pneumonias, and finally confirmed as PV stenosis. When a patient presents for nonspecific respiratory symptoms without evidence of infection after ablation therapy and image findings show chronic and repetitive parenchymal abnormalities confined in localized portion, the possibility of PV stenosis should be considered.

OBJECTIVETo explore the efficacy and feasibility of color Doppler flow imaging (CDFI)-guided inferior vena caval filter (IVCF) insertion through the right internal jugular vein for prevention of pulmonary embolism in patients with deep venous thrombosis (DVT).

METHODSThirty-eight patients with lower extremity DVT confirmed by clinical and CDFI examinations underwent IVCF insertion through the right internal jugular vein under guidance of CDFI for prevention of pulmonary embolism. The shape and position of IVCF were monitored by CDFI regularly. After 32 to 45 days, the retrievable filters were removed under CDFI guidance via the right internal jugular vein. All patients were followed up to monitor the occurrence of filter complications and pulmonary embolism PE.

RESULTSPreoperative CDFI clearly displayed the locations of the right internal jugular vein, inferior vena caval (IVC), bifurcation of the common iliac vein, and the bilateral renal veins in all the 38 patients. All the veins were free of anatomical variations or embolism. Under CDFI guidance, 23 retrievable IVCF and 15 permanent IVCF were placed without technical difficulty via the right internal jugular vein. Follow-up examination with CDFI and abdominal plain X-ray film showed that all the filters were placed in right positions with complete opening. The 23 retrievable filters were retrieved via the right internal jugular vein after 32-45 days. IVCF captured venous emboli in 14 cases (36.5%). None of the patients had filter displacement, tilting, or fracture or showed IVC perforation or the occurrence of pulmonary embolism.

CONCLUSIONCDFI-guided IVCF insertion via the jugular vein is safe and feasible. Compared with X-ray guidance, CDFI guidance is convenient and substantially reduces the procedural cost and avoids the risk of radiation exposure.
