Objective: To evaluate the efficacy of surgical treatment of aortic coarctation combined with descending aortic aneurysm in adult patients. Methods: This is a retrospective cohort study. Adult patients with aortic coarctation who were hospitalized in Beijing Anzhen Hospital from January 2015 to April 2019 were enrolled. The aortic coarctation was diagnosed by aortic CT angiography, and the included patients were divided into the combined descending aortic aneurysm group and the uncomplicated descending aortic aneurysm group based on descending aortic diameter. General clinical data and surgery-related data were collected from the included patients, and death and complications were recorded at 30 days after surgery, and upper limb systolic blood pressure was measured in all patients at discharge. Patients were followed up after discharge by outpatient visit or telephone call for their survival and the occurrence of repeat interventions and adverse events, which included death, cerebrovascular events, transient ischemic attack, myocardial infarction, hypertension, postoperative restenosis, and other cardiovascular-related interventions. Results: A total of 107 patients with aortic coarctation aged (34.1±15.2) years were included, and 68 (63.6%) were males. There were 16 cases in the combined descending aortic aneurysm group and 91 cases in the uncomplicated descending aortic aneurysm group. In the combined descending aortic aneurysm group, 6 cases (6/16) underwent artificial vessel bypass, 4 cases (4/16) underwent thoracic aortic artificial vessel replacement, 4 cases (4/16) underwent aortic arch replacement+elephant trunk procedure, and 2 cases (2/16) underwent thoracic endovascular aneurysm repair. There was no statistically significant difference between the two groups in the choice of surgical approach (all P>0.05). In the combined descending aortic aneurysm group at 30 days after surgery, one case underwent re-thoracotomy surgery, one case developed incomplete paraplegia of the lower extremity, and one case died; and the differences in the incidence of endpoint events at 30 days after surgery were similar between the two groups (P>0.05). Systolic blood pressure in the upper extremity at discharge was significantly lower in both groups compared with the preoperative period (in the combined descending aortic aneurysm group: (127.3±16.3) mmHg vs. (140.9±16.3) mmHg, P=0.030, 1 mmHg=0.133 kPa; in the uncomplicated descending aortic aneurysm group: (120.7±13.2) mmHg vs. (151.8±26.3) mmHg, P=0.001). The follow-up time was 3.5 (3.1, 4.4) years. There were no new deaths in the combined descending aortic aneurysm group, no transient ischemic attack, myocardial infarction or re-thoracotomy surgery, and one patient (1/15) suffered cerebral infarction and 10 patients (10/15) were diagnosed with hypertension. The differences in the occurrence of endpoint events during postoperative follow-up were similar between the two groups (P>0.05). Conclusion: In experienced centers, long-term prognosis of patients with aortic coarctation combined with descending aortic aneurysm is satisfactory post surgical intervention.

Compression of the airway is relatively common in pediatric patients, although it is often an unrecognized complication of congenital cardiac and aortic arch anomalies. Aortopexy has been established as a surgical treatment for tracheobronchial obstruction associated with vascular anomaly, aortic arch anomaly, esophageal atresia, and tracheoesophageal fistula. The tissue-to-tissue arch repair technique could result in severe airway complication such as compression of the left main bronchus which was not a problem before the correction. We report three cases of corrective open heart surgery monitored by intraoperative bronchoscopy performed during prebypass, and performed immediately before weaning from bypass, to evaluate tracheobronchial obstruction caused by congenital, complex cardiac anomalies in the operating room.

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.

OBJECTIVEBalloon angioplasty is an alternative to surgical repair for coarctation of the aorta in children. However, its role in the treatment of neonates and infants younger than 3 months old remains controversial. The purpose of this study was to evaluate the efficacy and safety of balloon angioplasty for native coarctation by comparing children in different age groups.

METHODThis is a retrospective clinical study including 37 children treated with balloon angioplasty for native coarctation from January 2006 to December 2012. A total of 37 patients consisting of 26 boys and 11 girls underwent the procedure, with median age 10 months (range from 7 days to 6 years) and the mean body weight was 6.3 (2.5-17.0) kg. The indication of the procedure includes discrete native coarctation without aortic arch hypoplasia and a peak-to-peak systolic pressure gradient > 20 mmHg (1 mmHg = 0.133 kPa) across aortic coarctation. During one year follow-up, the approach artery injury, recoarctation and aneurysm formation were particularly assessed.

RESULTWe classified these patients into two groups according to their age. Group A consisted of 25 patients younger than 3 months and Group B of 12 patients older than 3 months. There was no significant difference between the two groups in systolic pressure gradient before balloon angioplasty (P > 0.05). The mean peak systolic gradient decreased from (38 ± 18) mmHg to (12 ± 11) mmHg immediately after angioplasty in group A and from (47 ± 18) to (17 ± 12) mmHg in group B (P = 0.000 for both). Meanwhile, the mean diameter of the coarctation segment increased from (1.8 ± 0.7) to (3.7 ± 1.1) mm after angioplasty in group A and from (2.6 ± 1.5) to (5.5 ± 1.8) mm in group B (both P = 0). The initial successful balloon angioplasty (immediate postangioplasty peak pressure gradient < 20 mmHg) was achieved in all the 37 patients; 32 patients (86.5%) have been followed up for one year. Approach arterial complications occurred in 3 patients (9.4%), all of whom were in Group A (P = 0.537). Two patients had decreased femoral artery pulse and one required surgical repair for a postoperative pseudoaneurysm at left carotid artery. At follow-up, 8 patients (25.0%) developed recoarctation, with 6 cases in Group A and 2 in Group B. There was no significant difference between groups A and B in the recoarctation rate (P = 1.000). Among them, 7 patients underwent repeat balloon angioplasty, and all showed successful relief of coarctation, and one patient required surgical repair. Two patients (2/37, 5.4%) had small aneurysms of the descending aorta immediately after balloon angioplasty, with one patient in each group (12/25 vs.1/12, P = 0.755).Late aneurysm development has not been observed in the 17 patients who have had a follow-up CTA or MRA study.

CONCLUSIONBalloon angioplasty of discrete native coarctation is effective and safe in children both younger and older than 3 months with similar incidence of approach arterial complication, recoarctation and aneurysm formation.

The purpose of this study was to explore the clinical value of ECG-gated dual-source CT angiography (DSCTA) in evaluating coarctation of aorta (CoA). 23 patients suspected with CoA underwent DSCTA and transthoracic echocardiography (TTE). Surgical results were taken as reference standard. 23 patients were diagnosed with CoA, 12 cases had focal stenosis of aorta, while 11 had tubular stenosis. 19 cases were associated with other cardiovascular malformations, including 5 cases of hypoplastic aortic arch, 5 of patent ductus arteriosus, 10 of ventricular septal defect, 2 of bicuspid aortic valve, 4 of collateral arteries, 2 of aberrant left subclavian artery and 2 of persistent left superior vena cava, respectively. The mean diameter of stenotic segment of aorta was (7.0 +/- 3.7) mm. In 9 patients with tubular CoA, the diameter and length of stenotic segment of aorta were (6.2 +/- 7. 3) mm and (29.2 +/- 5.9) mm, respectively. The accuracies of DSCTA and TTE in the diagnosis of CoA were 100% and 91.3% (P > 0.05), respectively. It is well concluded that ECG-gated DSCTA could accurately evaluate CoA and associated cardiovascular malformations, and provide detailed anatomic information before surgery.

OBJECTIVETo demonstrate an effective operation of extra-anatomic bypass for complex aortic coarctation in adults.

METHODSBetween July 1997 and October 2010, 51 patients underwent extra-anatomic aortic bypass. There were 39 male and 12 female patients. Mean age was (40 ± 14) years (ranging from 18 to 63 years). Operative technique of extra-anatomic bypass consisted of performing an ascending-to-descending or abdominal or femoral aorta bypass (8, 39 and 4 patients). Concomitant procedures were performed in 38 patients: 10 isolated aortic valve replacements (AVR), 11 aortic root replacements (Bentall), 4 ascending aorta replacements including 3 concomitant AVR, 5 mitral valve replacements including 3 concomitant AVR, 4 ventricular septal defect correcting with AVR, and 4 coronary artery bypass graft.

RESULTSMean follow-up time was (30 ± 9) months (ranging from 5 to 60 months). Two patients were reoperated for hemorrhage in descending aorta anastomosis, one of whom was dead of multiple organ failure in perioperative period. Upper-extremity blood pressure after coarctation correction with extra-anatomic aortic bypass was significantly improved (< 10 mmHg, 1 mmHg = 0.133 kPa). Arterial hypertension was well improved, except 10 patients controlled with less drug therapy. All grafts were patent without obstruction or pseudoaneurysm formation in the follow-up period evaluated by vascular ultrasound and computed tomographic angiogram.

CONCLUSIONExtra-anatomic aortic bypass is a safe and effective option for complex aortic coarctation in adults.

Although outcomes of neonatal cardiac surgery have dramatically improved in the last two decades, low body weight still constitutes an important risk factor for morbidity and mortality. In particular, cardiac surgery in neonates with very low birth weight (< or =1.5 kg) is carried out with greater risk because most organ systems are immature. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,480 gram neonate.

OBJECTIVETo sum up one-stage complete correction of infantile aortic coarctation (CoA) or interrupted aortic arch (IAA) associated with intracardiac anomalies through median sternotomy.

METHODSThe clinical data of 52 infants with CoA or IAA associated with intracardiac anomalies from May 2004 to March 2010 was analyzed. There were 32 male and 20 female, aged from 25 d to 7 months with a mean of (2.03 ± 0.15) months, weighted from 2.5 to 8.0 kg with a mean of (3.9 ± 0.5) kg. All of intracardiac defect were corrected by self-arcula cordisand. Forty cases with CoA were underwent by operative techniques, including resection with end to side anastomosis, extended end to side anastomosis (n = 34), and vertical incision and cross joint (n = 3). Three cases of pseudo-CoA were cut and ductus arteriosus or ligamentum arteriosus and dissected arch. Twelve cases of IAA were underwent by extended end to side anastomosis.

RESULTSThe time of cardiopulmonary bypass was (98 ± 41) min, and all patients hemorrhaged (78 ± 13) ml during operation. One case of IAA associated with double outlet right ventricle died after 43 d post-operation because of left bronchial stenosis. The other patients were in good condition. The rate of aneurysm formation was 11% in 1 to 6 years' follow-up.

CONCLUSIONSOne-stage complete correction of infantile CoA or IAA associated with intracardiac anomalies through median sternotomy yields excellent intermediate surgical results. This operative approach is beneficial, not only with shorten period of therapy and loss operative cost.

Despite increased interest in bloodless cardiac surgery, its use has been mostly confined to adult patients. Especially, bloodless pediatric cardiovascular surgery using cardiopulmonary bypass has been avoided mainly due to hemodilution. Authors recently experienced a case of bloodless cardiac surgery in a 2.8 kg-weighing neonate whose parents were Jehovah's Witness.
