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.

Secondary hypertension occurs in a significant proportion of adult patients (~10%). In young patients, renal causes (glomerulonephritis) and coarctation of the aorta should be considered. In older patients, primary aldosteronism, obstructive sleep apnoea and renal artery stenosis are more prevalent than previously thought. Primary aldosteronism can be screened by taking morning aldosterone and renin levels, and should be considered in patients with severe, resistant or hypokalaemia-associated hypertension. Symptoms of obstructive sleep apnoea should be sought. Worsening of renal function after starting an angiotensin-converting enzyme inhibitor suggests the possibility of renal artery stenosis. Recognition, diagnosis and treatment of secondary causes of hypertension lead to good clinical outcomes and the possible reversal of end-organ damage, in addition to blood pressure control. As most patients with hypertension are managed at the primary care level, it is important for primary care physicians to recognise these conditions and refer patients appropriately.

OBJECTIVE: To evaluate the safety of surgical repair for neonatal aortic coarctation combined with ventricular septal defect.
 METHODS: Twenty-three aortic coarctation neonates received surgical treatment and their clinical data between April, 2013 and May, 2015 were analyzed retrospectively. All patients underwent coarctation repair + ventricular septal defect repair and mild hyperthermia cardiopulmonary bypass under the condition of general anesthesia. All patients were subjected to delayed sternal closure.
 RESULTS: One patient died at early post-operation, and no one died during 2-27 months' follow-up. Operation time, cardiopulmonary bypass time, aortic cross-clamp time, ICU stay time, mechanical ventilation time, delayed sternal closure time, and post-operative hospital stay time were (192.7±43.4) min, (132.4±26.4) min, (65.3±18.4) min, (185.3±56.4) h, (42.4±24.5) h, (36.3±18.6) h, and (15.3±4.6) d, respectively. Post-operative complications presented in 12 patients, including post-operative hemorrhage in 6 patients, acute renal insufficiency in 4 patients, wound infection in 1 patient, and post-operative coarctation of the aorta in 1 patient. 
 CONCLUSION One-stage complete repair for severe aortic coarctation combined with ventricular septal defect in neonates is safe, and the outcomes are satisfied. Fully free of the aortic arch and individual aorta reconstruction are the keies to successful operation.

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.

Although the treatment of aortic coarctation in adults with the use of stents has shown favourable results and reduced complications, there have been few studies involving elderly patients. We highlight the clinical challenges faced in the management of such patients, with attention to severe calcification at the coarctation site. The midterm results were good in our patient, showing an improvement in blood pressure control and maintenance of stent patency.

OBJECTIVETo analyze the surgical strategy and result of one-stage repair for congenital aortic arch disease associated with other cardiac anomalies.

METHODSBetween April 1993 and November 2009, 25 consecutive patients aged 26 d to 6.5 years underwent one-stage repair for congenital aortic arch disease with other cardiac anomalies. Among them, 6 patients had coarctation of aorta, 6 patients had interrupted aortic arch, and 13 cases had hypoplasia of aortic arch. The surgical techniques include excision of the anterior wall of pulmonary artery, resection of patent ductus arteriosus tissue, aortic arch reconstruction with autologous pulmonary artery wall, reconstruction of the pulmonary artery and repair of the associated defects.

RESULTSTwenty-four patients survived and recovered uneventfully. One patient died of pulmonary hypertension crisis in hospital. The reconstruction of the aorta and the correction of the intracardiac anomalies were proved by postoperative echocardiography and CT scan. There were no neurological or other complications. The follow-up showed that all patients developed normally and there were no restenosis of the aorta arch.

CONCLUSIONSWith the benefits of growth potential and less tension, autologous pulmonary artery tissue is an optimal choice in aortic arch reconstruction. One-stage repair of congenital aortic arch disease associated with other cardiac anomalies can achieve good results.

OBJECTIVEAlthough NuMED Cheatham-Platinum (CP) stent was specifically designed to treat vascular obstructions associated with congenital heart disease (CHD), its application in pediatric patients is relatively uncommon, especially in the pulmonary artery stenosis. The aim of this study was to evaluate the immediate-, early- and intermediate-term results of CP stent implantation in the treatment of vessel stenosis associated with CHD in children and adolescents.

METHODSFrom August 2005 to May 2007, 5 consecutive patients (3 boys and 2 girls) diagnosed as vascular stenosis associated with CHD underwent CP stent implantation in our institution. One patient had native coarctation of the aorta (CoA) and four patients had pulmonary artery stenosis. The median age and weight of patients were 12 years (range 4 - 15 years) and 24 kg (range 20 - 51 kg), respectively. The CP stent and NuMED Balloon-in-Balloon catheter were selected according to digital subtracted angiography measurements. After checking for correct position by angiography, the inner balloon and outer balloon inflated successively to expand the stent to desired diameter.

RESULTSTotally 6 stent placement procedures were performed and 8 CP stents (8-zig, 22 - 39 mm in length) were implanted in these 5 patients. All stents but one in a case of right pulmonary artery stenosis were immediately successfully placed in the target lesions without displacement during the procedures. For this case, a repeat procedure was performed and a second CP stent was reimplanted successfully 11 months later. After the procedure, the systolic pressure gradient across the stenosis decreased from (43.43 +/- 25.61) mm Hg (1 mm Hg = 0.133 kPa) to (3.29 +/- 3.09) mm Hg (t = 4.320, P < 0.01) and the narrowest diameter of the stenotic vessels increased from (6.86 +/- 2.04) mm to (13.44 +/- 4.02) mm (t = -4.508, P < 0.01). The percentage of pulmonary artery flow to the ipsilateral lung increased from 11.0% and 13.0% to 47.5% and 52.2% after the procedure in 2 cases of unilateral pulmonary artery branch stenosis, respectively. The ratio of right ventricular to aortic systolic pressure decreased from 62.3% and 72.2% to 27.0% and 33.3% in 2 cases of bilateral branch pulmonary artery stenosis, respectively. Upper limb blood pressure of one case of native CoA dropped greatly from 206/133 mm Hg to 156/95 mm Hg. During a median follow-up of 20 months (range 13 - 34 months), the results have been stable without complications except 2 stents which developed intrastent restenosis 6 months after the procedure.

CONCLUSIONOur experience suggests that the CP stent implantation is safe and feasible for the treatment of vessel stenosis associated with CHD in children and adolescents. The immediate-, early- and interim results are encouraging, but long-term results remain to be further evaluated and demand many more cases to be studied.
