Objective
To explore the feasibility of transcatheter closure of congenital heart disease (CHD) under the guidance of transthoracic echocardiography (TTE).
Methods
A total of 37 patients with CHD who received transcatheter closure under the guidance of transthoracic echocardiography from November 2013 through November 2015 in our hospital were recruited. There were 15 males and 22 females, aged 1 to 16 years. Among them 32 patients suffered atrial septal defect and 5 patients had patent ductus arteriosus. The transcatheter closure of CHD was performed under the guidance of TTE. The patients underwent echocardiography follow-up at one, three and six months after surgery.
Results
Closure devices were successfully implanted in 37 patients under TTE guidance. The procedure was simple and safe. During the follow-up, no severe complication such as valvular injury, pericardial effusion, residual shunt and peripheral vascular injury occurred.
Conclusion
Transcatheter closure of CHD under TTE guidance is a feasible method and worth further clinical application.
Objective
To evaluate the efficacy of pulmonary surfactant (PS) on severe acute respiratory distress syndrome (ARDS) in different age baby with congenital heart disease.
Methods
We divided 43 baby patients into two separate groups including a little baby group (12 patients with age less than 3 months) and an infants group (31 patients with age of 3 months to one year). Both groups of patients were treated with intratracheal PS at the same time. The clinical data were collected and analyzed.
Results
The little baby group had lower body weight. There was no statistical difference in the cardiopulmonary bypass (CPB) time, operation blocking time, mechanical ventilation time, ICU stay time between the two groups (P>0.05). Before treatment, arterial partial presurre of oxygen (PaO2), fractional oxygen concentration in inspire gas (FiO2), the ratio of arterial PO2 to the inspired oxygen fraction (P/F) and arterial-alveolar N2 difference or gradient (a/A) had no difference between the two groups (P>0.05). After treatment, PaO2 and P/F of both groups were significantly lower than before (P<0.05), and FiO2 and P/F were significantly higher than before (P<0.05). After 24 h of treatment, PaO2 and P/F of the little baby group was significantly higher than that of the infants group (P<0.05), and FiO2 and P/F were significantly lower than those of the infants group (P<0.05).
Conclusion
PS treating severe ARDS in little baby with congenital heart disease has better effect than infants.
ObjectiveTo evaluate the application value and significance of pulse indicator continuous cardiac output (PiCCO) in perioperative treatment of adult congenital heart disease (ACHD).
MethodsBetween June 2014 and June 2015, 100 adult patients (44 females and 56 males) underwent congenital heart disease operation. Patients were randomly divided into a PiCCO group and an experience treatment (control) group. According to the data of PiCCO detection, the PiCCO group was treated with vasoactive drugs and liquid balance management, the control group was treated by routine monitoring data. The clinical effectiveness of the two groups was compared.
ResultsThe ventilator time, ICU time and length of stay in the PiCCO group were significantly shorter than those in the control group with statistical differences (P=0.02, 0.03, 0.04). The drug dosage (dopamine, milrinone) during ICU were higher in the PiCCO group than those in the control group (P<0.01, P=0.04). There was no mortality in both groups. No significant difference was found in the incidence of postoperative complications between the two groups (P>0.05).
ConclusionThe application of PiCCO in the perioperative treatment of adult congenital heart disease can promote the early recovery of ACHD patients, and has a certain safety and effectiveness. Actively vasoactive drugs application to maintain circulation early in ICU has positive effect on the patient's recovery.
Objective To confirm the changes of pulmonary artery pressure, neo pulmonary artery stenosis and reoperation in children with unilateral absence of pulmonary artery (UAPA) undergoing pulmonary artery reconstruction. Methods The clinical data of the infants with UAPA undergoing pulmonary artery reconstruction in our hospital from February 19, 2019 to April 15, 2021 were analyzed. Changes in pulmonary artery pressure, neo pulmonary artery stenosis and reoperation were followed up. Results Finally 5 patients were collected, including 4 males and 1 female. The operation age ranged from 13 days to 2.7 years. Cardiac contrast-enhanced CT scans were performed in all children, and 2 patients underwent pulmonary vein wedge angiography to confirm the diagnosis and preoperative evaluation. Preoperative transthoracic echocardiography and intraoperative direct pulmonary arterial pressure measurement indicated that all 5 children had pulmonary hypertension, with a mean pulmonary arterial pressure of 31.3±16.0 mm Hg. Pulmonary arterial pressure decreased immediately after pulmonary artery reconstruction to 16.8±4.2 mm Hg. The mean follow-up time was 18.9±4.7 months. All 5 patients survived during the follow-up period, and 1 patient had neo pulmonary artery stenosis or even occlusion and was re-operated. Conclusion Pulmonary artery reconstruction can effectively alleviate the pulmonary hypertension in children with UAPA. The patency of the neo pulmonary artery should be closely followed up after surgery, and re-pulmonary angioplasty should be performed if necessary.
ObjectiveTo evaluate the possibility of monitoring regional tissue oxygen saturation by near-infrared spectroscopy (NIRS) for early predicting adverse events in patients with pulmonary atresia.MethodsTwenty-six patients aged under 3 months who were diagnosed with pulmonary atresia and admitted to cardiovascular intensive care unit in our hospital between January 2016 and May 2017, accepted regional tissue oxygenation (cerebral and splanchnic) by near-infrared spectroscopy. There were 19 males and 7 females at age of 2–89 days. A total of 625 times of heart rate, blood pressure, pulse saturation, regional tissue oxygenation, and 98 serum lactate were retrospectively analyzed. The relationship of the tissue oxygen saturation and clinical adverse events was explored.ResultsThe adverse event by routine monitoring was 69 (11.04%) person-time: isolated hypoxia in 27, hypoxia combined increased lactate in 16, hypotension in 6, hypotension combined increased lactate in 17, isolated increased lactate in 3. A reduction of 12.80% in cranial oxygen predicted the high probability of adverse events, with a sensitivity of 85.30% and a specificity of 87.00%. A reduction of 20.60% in splanchnic oxygen predicted the high probability of adverse event, with a sensitivity of 73.50% and a specificity of 91.2%. On average, the splanchnic oxygenation had fell 3 minutes before a reduction of blood pressure, or 45 minutes before an increase in lactate.ConclusionFor preoperative patients with pulmonary atresia, a fall of 12.80% in cranial oxygen saturations, or of 20.60% in splanchnic oxygen saturation, should attract clinician’s awareness.
Objective To study the inflammation response and the biocompatibil ity of valved bovine jugular vein conduit (BJVC) and valved bovine jugular vein patch (VBJV-P) in treating complex congenital heart disease (CHD). Methods From December 2007 to March 2008, 16 patients with complex CHD were treated. Of 16 patients, 6 underwent conjunction right ventricular to pulmonary artery with BJVC and broaden right ventricular outflow tract (RVOT) with VBJV-P (BJVC group), and 10 underwent broaden RVOT with self pericardial patch (control group). In BJVC group, there were 3 males and 3 females, aging (5.6 ± 3.6) years, and including 1 case of type I truncus arteriosus, 1 case of type I truncus arteriosus with ventricular septal defect and patent foramen ovale, 1 case of congenital pulmonary atresia with ventricular septal defect and patent arterial duct, and 3 cases of Fallot’s tetrad. In control group, there were 5 males and 5 females, aging(4.3 ± 3.1) years, all being Fallot’s tetrad. The periphery vein blood of the two groups was collected during operation and after operation, and the levels of cytokine were detected with ELISA method. Meanwhile the cl inical data of the two groups were collected. Results There were no significant differences at levels of TNF-α and IL-6 between BJVC group and control group 1 week after operation (P gt; 0.05), and there was significant difference at level of IL-10 [(25.7 ± 5.0) pg/mL vs (19.5 ± 4.7) pg/ mL, P lt; 0.05]. There were no significant differences at levels of IL-6 and IL-10 within groups both in control group and in BJVC group (P gt; 0.05) between 1 week after operation and the anesthesia inducing period. And there was significant difference at level of TNF-α in BJVC group [(77.0 ± 1.6) pg/mL vs (82.9 ± 1.3) pg/mL, P lt; 0.05] and in control group [(78.6 ± 3.4) pg/mL vs (83.1 ± 1.9) pg/mL, P lt; 0.05] between 1 week after operation and the anesthesia inducing period. There were no statistically significant differences (P gt; 0.05) in leukocyte count and body temperature between BJVC group and control group. The X-ray films showed no abnormal ity in BJVC group and control group before operation and after operation. No hepatic and renal dysfunction occurred in control group; and 2 patients had hepatic dysfunction, which may be caused by antibiotics. Conclusion BJVC has a good biocompatibil ity in treating complexty CHD.
ObjectiveTo summarize the experience of totally thoracoscopic cardiac surgery for ventricular septal defect.MethodsClinical data of 449 patients undergoing totally thoracoscopic cardiac surgery for ventricular septal defect from May 2008 to December 2018 in Shanghai Yodak Cardiothoracic Hospital were analyzed retrospectively. There were 232 male and 217 female patients, aged from 3 to 55 years with a mean age of 17.3±11.2 years.ResultsAll the operations were completed successfully. Mean operative time was 2.4±0.3 h. The mean extracorporeal circulation time and aortic cross-clamp time was 64.2±11.6 min and 28.4±10.7 min, respectively. Mechanical ventilation time and intensive care unit stay was 6.9±3.8 h and 20.5±5.6 h, respectively. Postoperation drainage quantity was 213.1±117.2 mL. The hospital stay was 6.9±1.3 d. Intraoperative and postoperative complications occurred in 11 patients (2.4%), including 1 patient of intraoperative reoperation, 3 patients of reoperation for bleeding, 3 patients of the incision infection, 2 patients of small residual shunt, 1 patient of right femoral artery incision stenosis complicated by thromboembolism and 1 patient of right pleural cavity pneumothorax. The mean follow-up time was 72.2±33.9 months. During the period, there was no reoperation, but 2 patients of ventricular septal defect small residual shunt, 1 patient of mild-moderate mitral valve and 1 patient of mild-moderate aortic valve incompetence, respectively. During the period, heart function of the patients was NYHAⅠ-Ⅱ.ConclusionTotally thoracoscopic cardiac surgery for ventricular septal defect is a safe and effective treatment, with few serious complications, fast recovery for patients and good short to medium-term outcomes.
ObjectiveTo investigate the effect of pulmonary ultrasound on pulmonary complications in ultra-fast-track anesthesia for congenital heart disease surgery.MethodsIn 2019, 60 patients with congenital heart diseases underwent ultra-fast-track anesthesia in Shenzhen Children's Hospital, including 34 males and 26 females with the age ranging from 1 month to 6 years. They were randomly divided into a normal group (group N, n=30) and a lung ultrasound optimization group (group L, n=30). Both groups were used the same anesthesia method and anesthetic compatibility. The group N was anesthetized by ultra-fast-track, the tracheal tube was removed after operation and then the patients were sent to the cardiac intensive care unit (CCU). After operation in the group L, according to the contrast of pre- and post-operational lung ultrasonic examination results, for the patients with fusion of B line, atelectasis and pulmonary bronchus inflating sign which caused the increase of lung ultrasound score (LUS), targeted optimization treatment was performed, including sputum suction in the tracheal tube, bronchoscopy alveolar lavage, manual lung inflation suction, ultrasound-guided lung recruitment and other optimization treatments, and then the patients were extubated after lung ultrasound assessment and sent to CCU. The occurrence of pulmonary complications, LUS, oxygenation index (OI), extubation time, etc were compared between the two groups.ResultsCompared with the induction of anesthesia and 1 hour after extubation of the two groups, the incidence of pulmonary complications in the group L (18 patients, 60.0%) was lower than that in the group N (26 patients, 86.7%, χ2= 4.17, P=0.040) and the rate of patients with LUS score reduction was higher in the group L (15 patients, 50.0%) than that in the group N (7 patients, 23.3%, χ2=4.59, P=0.032). The correlation analysis between the LUS and OI value of all patients at each time point showed a good negative correlation (P<0.05). Extubation time in the group L was longer than that in the group N (18.70±5.42 min vs. 13.47±4.73 min, P=0.001).ConclusionUltra-fast-track anesthesia for congenital heart disease can be optimized by pulmonary ultrasound examination before extubation, which can significantly reduce postoperative pulmonary complications, improve postoperative lung imaging performance, and help patients recover after surgery, and has clinical application value.
ObjectiveTo explore risk factors associated with mortality and restenosis after the surgery for congenital pulmonary venous stenosis (CPVS) combined with congenital heart disease.MethodsFrom May 2007 to August 2019, 58 patients received surgical relief of CPVS combined with congenital heart disease, including 24 males and 34 females, aged 17.2±26.3 months, weighing 8.8±8.2 kg. Endpoints were death and restenosis, and the risk factors were analyzed. A univariate and multivariate risk analyses were performed.ResultsPreoperative pulmonary venous stenosis severity score (PVSSS) was 4.5±2.7. Average pulmonary vein counts with CPVS was 1.9±1.0. There were 2 (3.4%) early deaths. The mean follow-up time was 2-145 (49.8±40.0) months. The 1-, 2-, 3- and 5-year overall survival rates were 86.7%, 81.3%, 78.5% and 73.6%, respectively, and the pulmonary venous restenosis-free rates were 79.6%, 68.5%, 68.5% and 68.5%, respectively. Preterm birth was an independent risk factor for mortality. The pulmonary venous peak flow rate ≥1.2 m/s at discharge was an independent risk factor for mortality and restenosis.ConclusionThe prognosis of CPVS is still poor. Postoperative residual stenosis at discharge is an independent risk factor for death and restenosis.
ObjectiveTo 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.ResultsThe 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).ConclusionTVP is a feasible treatment for adult patients with CCTGA. The increase of preoperative RVEDD is a risk factor for long-term mortality.
