Abstract
BACKGROUND To assess the feasibility and early outcome of continuous cerebral and myocardial selective perfusion (CCMSP) during aortic arch surgery in neonates. METHODS We performed a single-center retrospective study between 2008 and 2019 on neonates who underwent aortic arch surgery with or without associated heart lesion repair. CCMSP with moderate hypothermia levels (28°C) was achieved using selective brachiocephalic artery and ascending aorta cannulation. Target rates of cerebral and myocardial perfusion were 25 to 35 mL/kg/min and 150 ml/m2/min. Cardiopulmonary bypass (CPB) variables and clinical outcomes were analyzed. RESULTS Overall, 69 neonates underwent either isolated aortic arch repair (n = 31) or aortic arch repair with ventricular septal defect (VSD) closure (n = 38). Age and weight medians were 8 [6 to 15] days and 3.4 [2.9-3.5] kg, respectively. Mean CPB and aortic clamping times were 134 ± 47 and 26 ± 5 minutes for isolated aortic arch repair, and 159 ± 47 and 75 ± 30 minutes for aortoplasty accompanied by VSD closure. Mean CCMSP time was 52 ± 21 minutes with cerebral rate of 32.6 ± 10 mL·kg-1 ·min-1 . Overall in hospital survival was 98.5% (68/69). Major complications were: postoperative cardiac failure requiring mechanical support followed by stroke (n = 1; 1.44%) and transient renal failure requiring dialysis (n = 2; 2.89%). Neither myocardial nor digestive complication occurred. CONCLUSION CCMSP is a safe and reproducible strategy for cerebral, myocardial and visceral protection in neonatal aortic arch repair, with or without VSD closure, resulting in low complication and mortality.

Selective versus standard cerebro-myocardial perfusion in neonates undergoing aortic arch repair: A multi-center study. Artif Organs 2019; 43:728-735. [PMID: 30698825 DOI: 10.1111/aor.13430] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2018] [Revised: 01/19/2019] [Accepted: 01/24/2019] [Indexed: 11/30/2022]
Abstract
The results of neonatal aortic arch surgery using cerebro-myocardial perfusion were analyzed. Selective cerebral and myocardial perfusion, using two separate pump rotors, was compared with standard perfusion, using a single pump rotor with an arterial line Y-connector. Between May 2008 and May 2016, 69 consecutive neonates underwent arch repair using either selective cerebro-myocardial perfusion (Group A, n = 34) or standard perfusion (Group B, n = 35). The groups were similar for age, weight, BSA, prevalence of one-stage or staged repair, and single ventricle palliation; male gender was more frequent in Group A. The duration of the cerebro-myocardial perfusion was comparable (27 ± 8 vs. 28 ± 7 min, P = 0.9), with higher flows in Group A (57 ± 27 vs. 39 ± 19 mL/kg/min, P = 0.01). Although cardioplegic arrest was more common in Group B (13/34 vs. 23/35, P = 0.03), the duration of myocardial ischemia was longer in Group A (64 ± 41 vs. 44 ± 14 min, P = 0.04). There was 1 hospital death in each group, with no permanent neurological injury in either group. Cardiac morbidity (1/34 vs. 7/35, P = 0.02) was more common in Group B, while extracardiac morbidity was similar in both the groups. During follow-up (3.2 ± 2.4 years), 5 late deaths occurred with a comparable 5-year survival rate (75 ± 17% vs. 88 ± 6%, P = 0.7) and freedom from arch reintervention (86 ± 6% vs. 84 ± 7%, P = 0.6). Risk of cardiac morbidity was greater with standard cerebro-myocardial perfusion (OR = 5.2, CI 3.3-6.8, P = 0.001) and with perfusion flows less than 50 mL/kg/min (OR 3.7, CI 1.87-5.95, P = 0.04). Cerebro-myocardial perfusion is a safe and effective strategy to protect the brain and heart in neonates undergoing arch repair. Selective techniques using higher perfusion flows may further attenuate cardiac morbidity.

Abstract
Hypoplastic left heart syndrome (HLHS) is a rare and severe congenital cardiac defect. Approximately 1000 infants are born with HLHS in the United States every year. Healthcare collaboratives over the last decade have focused on sharing patient experiences and techniques in an effort to improve outcomes. In 2010, cardiologists and patient families joined together to improve the care of HLHS patients by forming the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC). Sixty-six of the approximately 110 institutions caring for patients with HLHS in the United States and Canada are now members of NPC-QIC. In 2017, cardiovascular perfusionists joined the collaborative as another specialty involved in the care of HLHS patients. Perfusionists and cardiac surgeons developed the collaborative’s first conduct of perfusion survey for the Norwood Stage 1 procedure, specifically targeting the provision of cardiopulmonary bypass for patients with HLHS. This manuscript discusses the results of this survey, unveiling a significant variance in the conduct of perfusion for this patient population.

Abstract
BACKGROUND The approach (lateral thoracotomy versus median sternotomy) to repair coarctation of the aorta is frequently based on arch dimensions from the preoperative echocardiogram. Few studies have assessed the relationship between preoperative arch dimensions and late postoperative outcome. This study aimed to define how preoperative arch dimensions relate to late outcomes and identify long-term predictors of a successful operation. METHODS We performed a retrospective review of 102 neonates and infants undergoing isolated coarctation repair by lateral thoracotomy between 2003 and 2012. Long-term surgical success was defined based on the following five factors: corrected arch gradient below 20 mm Hg, blood pressure cuff gradient below 15 mm Hg, systolic blood pressure below the 95th percentile during the clinic visit, no antihypertensive medication use, and freedom from reintervention. Regression analysis was performed to identify factors that would predict the need for reintervention and long-term success. RESULTS At a median of 6 years of follow-up, long-term success was achieved in 63% (56 of 89) of patients, and 94% (96 of 102) were free of reintervention. Bivariate analysis showed that patients requiring reintervention had smaller absolute isthmus dimension (p = 0.04). No significant predictors for reintervention or long-term success could be identified, although a larger distal transverse arch dimension may play a role in long-term success (hazard ratio, 0.7; 95% confidence interval, 0.05 to 1.0; p = 0.06). CONCLUSIONS Aortic arches of various dimensions were successfully repaired by lateral thoracotomy. No significant predictors for reintervention or long-term success could be identified, although the distal transverse arch dimension may play a role in long-term success.

Selective Cerebro-Myocardial Perfusion in Complex Neonatal Aortic Arch Pathology: Midterm Results. Artif Organs 2018; 42:457-463.

Abstract
Aortic arch repair in newborns and infants has traditionally been accomplished using a period of deep hypothermic circulatory arrest. To reduce neurologic and cardiac dysfunction related to circulatory arrest and myocardial ischemia during complex aortic arch surgery, an alternative and novel strategy for cerebro-myocardial protection was recently developed, where regional low-flow perfusion is combined with controlled and independent coronary perfusion. The aim of the present retrospective study was to assess short-term and mid-term results of selective and independent cerebro-myocardial perfusion in neonatal aortic arch surgery. From April 2008 to August 2015, 28 consecutive neonates underwent aortic arch surgery under cerebro-myocardial perfusion. There were 17 male and 11 female, with median age of 15 days (3-30 days) and median body weight of 3 kg (1.6-4.2 kg), 9 (32%) of whom with low body weight (<2.5 kg). The spectrum of pathologies treated was heterogeneous and included 13 neonates having single-stage biventricular repair (46%), 7 staged biventricular repair (25%), and 8 single-ventricle repair (29%). All operations were performed under moderate hypothermia and with a "beating heart and brain." Average cardiopulmonary bypass time was 131 ± 64 min (42-310 min). A period of cardiac arrest to complete intra-cardiac repair was required in nine patients (32%), and circulatory arrest in 1 to repair total anomalous pulmonary venous connection. Average time of splanchnic ischemia during cerebro-myocardial perfusion was 30 ± 11 min (15-69 min). Renal dysfunction, requiring a period of peritoneal dialysis was observed in 10 (36%) patients, while liver dysfunction was noted only in 3 (11%). There were three (11%) early and two late deaths during a median follow-up of 2.9 years (range 6 months-7.7 years), with an actuarial survival of 82% at 7 years. At latest follow-up, no patient showed signs of cardiac or neurologic dysfunction. The present experience shows that a strategy of selective and independent cerebro-myocardial perfusion is safe, versatile, and feasible in high-risk neonates with complex congenital arch pathology. Encouraging outcomes were noted in terms of cardiac and neurological function, with limited end-organ morbidity.

Abstract
The benefit of blood cardioplegia (BCP) compared to crystalloid cardioplegia (CCP) is still debatable. Our aim was to systematically review and synthesize all available evidence on the use of BCP and CCP to assess if any modality provides superior outcomes in pediatric cardiac surgery. A systematic literature search of the PubMed and Cochrane databases was performed with respect to the PRISMA statement (end-of-search date: January 30th, 2017). We extracted data on study design, demographics, cardioplegia regimens, and perioperative outcomes as well as relevant biochemical markers, namely cardiac troponin I (cTnI), lactate, and ATP levels at baseline, after reperfusion and postoperatively at 1, 4, 12, and 24 h as applicable. Data were appropriately pooled using random and mixed effects models. Our systematic review includes 56 studies reporting on a total of 7711 pediatric patients. A meta-analysis of the 10 eligible studies directly comparing BCP (n = 416) to CCP (n = 281) was also performed. There was no significant difference between the two groups with regard to cTnI and Lac at any measured time point, ATP levels after reperfusion, length of intensive care unit stay (WMD: -0.08, 95% CI -1.52 to 1.36), length of hospital stay (WMD: 0.13, 95% CI -0.85 to 1.12), and 30-day mortality (OR 1.11, 95% CI 0.43-2.88). Only cTnI levels at 4 h postoperatively were significantly lower with BCP (WMD: -1.62, 95% CI -2.07 to -1.18). Based on the available data, neither cardioplegia modality seems to be superior in terms of clinical outcomes, ischemia severity, and overall functional recovery.

Abstract
We report a modified Norwood stage I procedure for tricuspid atresia, transposition of great arteries, and hypoplastic right aortic arch with complete vascular ring. In this technique, we applied dual arterial cannulation to avoid circulation arrest during neoaortic reconstruction, and also corrected the arch laterality during the Norwood stage I palliation procedure. Pulmonary flow was supplied by the Blalock-Taussig shunt. Postoperative imaging revealed the patent left neoaortic arch, and the vascular ring was relieved with a patent tracheobronchial tree.

Abstract
BACKGROUND Antegrade cerebral perfusion (ACP) typically is used with deep hypothermia for cerebral protection during aortic arch reconstructions. The impact of ACP on cerebral oxygenation and serum creatinine at a more tepid 25 °C was studied in newborns and children. METHODS Between 2010 and 2014, 61 newborns and children (<5 years old) underwent aortic arch reconstruction using moderate hypothermia (25.0±0.9 °C) with ACP and a pH-stat blood gas management strategy. These included 44% Norwood-type operations, 30% isolated arch reconstructions, and 26% arch reconstructions with other major procedures. Median patient age at surgery was 9 days (range, 3 days-4.7 years). Cerebral oxygenation (NIRS) was monitored continuously perioperatively for 120 hours. Serum creatinine was monitored daily. RESULTS Median cardiopulmonary bypass (CPB) and cross clamp times were 181 minutes (range, 82-652 minutes) and 72 minutes (range, 10-364 minutes), respectively. ACP was performed at a mean flow rate of 46±6 mL/min/kg for a median of 48 minutes (range, 10-123 minutes). Cerebral and somatic NIRS were preserved intraoperatively and remained at baseline postoperatively during the first 120 hours. Peak postoperative serum creatinine levels averaged 0.7±0.3 mg/dL for all patients. There were 4 (6.6%) discharge mortalities. Six patients (9.8%) required ECMO support. Median postoperative length of hospital and intensive care unit (ICU) stay were 16 days(range, 4-104 days) and 9 days (range, 1-104 days), respectively. Two patients (3.3%) received short-term peritoneal dialysis for fluid removal, and none required hemodialysis. Three patients (4.9%) had an isolated seizure which resolved with medical therapy, and none had a neurologic deficit or stroke. CONCLUSIONS ACP at 25 °C preserved perioperative cerebral oxygenation and serum creatinine for newborns and children undergoing arch reconstruction. Early outcomes are encouraging, and additional study is warranted to assess the impact on late outcomes.

Abstract
PURPOSE Innominate artery cannulation has been widely adopted as a means to perform aortic arch reconstruction with continuous cerebral perfusion in the newborn. Although this technique has been subsequently utilized in infants and children, there is currently no data regarding the safety or efficacy in these older children. The purpose of this study was to review our experience with innominate artery cannulation for aortic arch reconstruction in patients beyond the neonatal period. METHODS This was a retrospective review of 42 infants and children who underwent aortic arch reconstruction using the technique of innominate artery cannulation with continuous cerebral perfusion. Of these procedures, 29 (69%) were primary arch reconstructions, while 13 (31%) were aortic arch reoperations. The median age at surgery was 8 months, and 22 patients underwent concomitant intracardiac repairs. RESULTS There was no operative mortality in this cohort of 42 patients undergoing aortic arch reconstruction. There was also no overt evidence of neurologic injury. Specifically, none of the patients demonstrated a neurologic deficit, clinical seizure, or unexpected delay in regaining a normal state of consciousness. The median duration of antegrade cerebral perfusion was 34 minutes. The median duration of hospital stay was 11 days. No patient required reoperation on the aortic arch with a median of 45-month follow-up. CONCLUSIONS Innominate artery cannulation is a safe and effective technique for aortic arch reconstruction in nonneonates. We conclude that antegrade cerebral perfusion is a useful technique for aortic arch reconstruction in this patient population.

BACKGROUND During the surgical repair of infants with congenital cardiac defects, there can be periods of decreased cerebral blood flow, particularly during deep hypothermic circulatory arrest. As a result, these infants are at increased risk for seizures and long-term neurodevelopmental difficulties. METHODS Thirty-two infants with congenital heart disease had continuous video-electroencephalographic (EEG) monitoring pre-, intra-, and postoperatively for 48 hours after surgery. RESULTS For patients requiring deep hypothermic circulatory arrest (n = 17) the EEG pattern for all patients became suppressed and eventually isoelectric below 25 °C. Two of the 32 infants had electrical seizures within the 48-hour monitoring period. Both required deep hypothermic circulatory arrest, and the burst pattern during recovery had rhythmic, sharp components that were high amplitude and often asynchronous between the hemispheres. The interval between the onset of seizure activity and initiation of the sharp burst pattern during surgery was 29 and 40 hours. This pattern was not observed during isoelectric recovery from infants who did not develop postoperative seizures. CONCLUSIONS The EEG in infants during deep hypothermic circulatory arrest displayed predictable changes. We identified an electroencephalographic pattern following the isoelectric period that may predict seizure development in the subsequent 48 hours.

Abstract
Hypoplastic left heart syndrome is a congenital heart defect characterized by hypoplasia of left heart structures. Over the past 3 decades, there have been advances in techniques and management in the care of these patients. We discuss shunt selection, operative strategies, transplantation, and outline various facets of management at the University of Florida. This is a review of the literature highlighting some of the technical aspects of the preoperative, operative, and postoperative care that are important in today's management of hypoplastic left heart syndrome.

Abstract
Controversy still exists concerning the use of deep hypothermic circulatory arrest (DHCA) and selective antegrade cerebral perfusion (SACP) for repair of aortic coarctation (CoA) with ventricular septal defect (VSD). This report therefore describes outcomes of patients undergoing continuous cerebral and myocardial perfusion (CCMP) under mild hypothermia compared with DHCA and SACP. Retrospective analysis was performed for 110 consecutive patients undergoing anatomic reconstruction of CoA with VSD closure between 1999 and 2011. Patients repaired under CCMP with mild hypothermia (32 °C) (group A, n = 60) were compared with those repaired under DHCA (18 °C) and SACP (group B, n = 50). In group A, the single arterial cannula perfusion technique was used for 15 patients (25 %), and the dual arterial cannula perfusion technique was used for 45 patients (75 %). The preoperative data were similar in the two groups. Group A had no hospital mortalities, compared with two mortalities (4 %) in group B. Group A had shorter myocardial ischemic and cardiopulmonary times, fewer delayed sternal closures, a shorter time to extubation, lower postoperative lactate levels, and fewer patients with low cardiac output requiring extracorporeal membrane oxygenation or with multiorgan failure than group B. During the postoperative course, no clinical or electrical neurologic events occurred in either group. The mean follow-up period was 5.2 ± 3.2 years for group A and 7.5 ± 3.1 years for group B (P = 0.048). One late death occurred in group B and no late deaths in group A. The actuarial survival for the two groups was similar (100 % for group A vs 96 % for group B; P = 0.264). The freedom from all types of cardiac reintervention was 96.7 % in group A and 89.6 % in group B (P = 0.688). All the patients were free of neurologic symptoms. The authors' perfusion strategy using CCMP with mild hypothermia for repair of CoA with VSD is feasible, safe, and associated with improved postoperative recovery and should be the method of choice.

Abstract
BACKGROUND Controversy still exists on the use of the optimal cardiopulmonary bypass (CPB) management in aortic coarctation (CoA) with ventricular septal defect (VSD) repair. We report the outcome of patients undergoing continuous cerebral and myocardial perfusion (CCMP) under mild hypothermia. METHOD This is a retrospective analysis of 60 consecutive patients undergoing anatomic reconstruction of CoA with VSD closure between 1999 and 2011. Single arterial cannula perfusion technique was used in 15 (25%) patients, and a dual arterial cannula perfusion technique was used in 45 (75%) patients. RESULTS There were no hospital or late mortalities. Average CPB time was 105 ± 28 minutes, aortic clamp 27 ± 7 minutes, and descending aortic cross-clamp time 24 ± 5 minutes. Average continuous cerebral perfusion flow was 64 ± 8 mL/kg per minute. No patient needed delayed sternal closure. Average duration of ventilation was 38 ± 20 hours, ICU stay 7 ± 3 days, and hospital stay 14 ± 6 days. No patient required revision for bleeding and/or extracorporeal membrane oxygenation support. No neurologic complications were noted. CONCLUSION A perfusion strategy using CCMP with mild hypothermia for CoA and VSD repair is feasible and safe.

Abstract
Neonatal patients with hypoplasia of the aortic arch constitute a heterogeneous group with a wide spectrum of severity. The milder end of the spectrum comprises patients with aortic coarctation and isthmus hypoplasia. At the other end of the spectrum are patients with severe transverse arch hypoplasia or hypoplastic left heart syndrome. The aim of this paper is to discuss the various strategies and surgical approaches available for this group of patients, focusing on the surgical decisions that influence individual patient management. Many of the things discussed are applicable to any neonatal arch problem. We also describe and discuss in detail our surgical technique for patients who undergo neonatal repair of a hypoplastic aortic arch via median sternotomy.

Abstract
OBJECTIVE Ideal temperature and flow rate for selective cerebral perfusion (SCP) are not known. We examined regional organ perfusion in a piglet SCP model. METHODS Three groups underwent SCP at 30 mL/kg/min at different temperatures (15°C, 25°C, and 32°C) and 4 groups remained at 25°C for SCP at different flow rates (10, 30, 50 and 75 mL/kg/min). Fluorescent microspheres were injected at 5 minutes of normothermic cardiopulmonary bypass (CPB), immediately before SCP, SCP 45 minutes, SCP 90 minutes, and 2 hours after CPB. Brain and lower body organs were collected to examine regional blood flow (RBF, mL/min/g). RESULTS At 2 hours after CPB, RBF of the 32°C group was higher than that of the 15°C group (P < .05) at the caudate nucleus and hippocampus; RBF of the 32°C group was higher than that of the 25°C and 15°C groups (P < .05) at the neocortex. No significant difference in RBF was observed among any of the 25°C groups at different flow rates. Also, there was no significant difference between the RBF to the left and right sides of brain in either the temperature or flow rate groups. RBF did significantly increase with temperature in the liver and quadriceps during SCP (P < .05). At the kidney, RBF at SCP 90 minutes was significantly higher than that at SCP 45 minutes when all temperature groups were combined (P < .05). CONCLUSIONS SCP at 32°C provides higher brain RBF 2 hours after CPB. Increasing SCP flow rate does not increase RBF significantly at 25°C. Higher temperature during SCP results in improved RBF to the liver and quadriceps.

Abstract
BACKGROUND The impact of various flows for selective cerebral perfusion (SCP) on cerebral oxidative stress in the immature brain is unknown. We examined early changes in cerebral markers of oxidative damage, apoptotic protein activation and histological outcome after different flows for SCP in a piglet model of deep hypothermic circulatory arrest (DHCA). METHODS Twenty piglets, randomly divided into four groups (each n = 5), were placed on cardiopulmonary bypass (CPB) at 20°C, then underwent DHCA for 60 minutes. SCP was conducted at flow rates of 0, 25, 50 and 80 ml·kg(-1)·min(-1) through the innominate artery in the DHCA, SCP 25, SCP 50, and SCP 80 groups, respectively. The animals were killed at 2 hours off CPB. Brain tissues were examined for the activity of SOD, MDA and caspase-3, and histological damage was quantitatively assayed by light microscopic examinations. RESULTS There were no significant differences in the activities of SOD, MDA and the SOD/MDA index between the groups. Caspase-3 activity significantly decreased in the SCP 25, SCP 50 and SCP 80 groups compared with the DHCA group. However, the caspase-3 level was higher in the SCP 80 group than in the SCP 25 and SCP 50 group. There were no significant correlations between MDA, SOD, SOD/MDA index and caspase-3. CONCLUSIONS In this acute model, under different flows for SCP, cerebral MDA and SOD activities show no change, whereas activated caspase-3 has a marked change. There was no relationship between oxidative stress, indicated by MDA and SOD, and apoptotic protein activation in the early phase after DHCA.

Abstract
OBJECTIVE To analyse the technique of neonatal aortic arch enlargement without cardiopulmonary bypass through a left posterior thoracotomy, as an adjunct to extended resection for Coarctation and severe arch hypoplasia. METHODS Ten neonates with coarctation, severe arch hypoplasia and a persistent ductus arteriosus (PDA) were subjected to arch repair through a left posterior thoracotomy. Nine of these patients had associated significant intracardiac anomalies; three of them received pulmonary artery (PA) banding. After exclusion from circulation, the roof of the intervening arch between left carotid and left subclavian was enlarged using a patch. After adequate reperfusion, a classic resection and extended end-to-end anastomosis was performed. Median age and weight were 5.5 (1-10) days and 3.3 (2.2-4.1) kg respectively. The median preoperative arch diameter was 1.07 (0.75-1.32) mm/kg body weight. RESULTS All patients could be successfully operated with this approach. The non-ischaemic and ischaemic aortic clamp times were 40 (15-68) and 23 (18-32) min, respectively. The median postoperative arch diameter achieved was 1.43 (1.06-1.46) mm/kg body weight. None of the patients had significant gradient early postoperatively. Two patients with recurrent stenosis were successfully treated with balloon dilatation (1) or surgery with cardiopulmonary bypass (CPB) (1). One patient has a corrected gradient of 16 mmHg in the proximal arch which is being observed. The remaining patients are free from stenosis at a median follow-up of 30.1 (13.2-57.8) months. CONCLUSIONS Use of PDA for lower body perfusion allows complex reconstruction of the arch without incurring lower body ischaemia. The extended resection could then be performed without excessive stretch. This modification saves these patients from undergoing a complex arch reconstruction with CPB in the early neonatal period.

Abstract
Simultaneous cerebro-myocardial perfusion has been described in neonatal and infant arch surgery, suggesting a reduction in cardiac morbidity. Here reported is a novel technique for selective cerebral perfusion combined with controlled and independent myocardial perfusion during surgery for complex or recurrent aortic arch lesions. From April 2008 to April 2011, 10 patients with arch pathology underwent surgery (two hypoplastic left heart syndrome [HLHS], four recurrent arch obstruction, two aortic arch hypoplasia + ventricular septal defect [VSD], one single ventricle + transposition of the great arteries + arch hypoplasia, one interrupted aortic arch type B + VSD). Median age was 63 days (6 days-36 years) and median weight 4.0 kg (1.6-52). Via midline sternotomy, an arterial cannula (6 or 8 Fr for infants) was directly inserted into the innominate artery or through a polytetrafluoroethylene (PTFE) graft (for neonates <2.0 kg). A cardioplegia delivery system was inserted into the aortic root. Under moderate hypothermia, ascending and descending aorta were cross-clamped, and "beating heart and brain" aortic arch repair was performed. Arch repair was composed of patch augmentation in five, end-to-side anastomosis in three, and replacement in two patients. Average cardiopulmonary bypass time was 163 ± 68 min (71-310). In two patients only (one HLHS, one complex single ventricle), a period of cardiac arrest was required to complete intracardiac repair. In such cases, antegrade blood cardioplegia was delivered directly via the same catheter used for selective myocardial perfusion. Average time of splanchnic ischemia during cerebro-myocardial perfusion was 39 ± 18 min (17-69). Weaning from cardiopulmonary bypass was achieved without inotropic support in three and with low dose in seven patients. One patient required veno-arterial extracorporeal membrane oxygenation. Four patients, body weight <3.0 kg, needed delayed sternal closure. No neurologic dysfunction was noted. Renal function proved satisfactory in all, while liver function was adequate in all but one. The present experience suggests that selective and independent cerebro-myocardial perfusion is feasible in patients with complex or recurrent aortic arch disease, starting from premature newborn less than 2.0 kg of body weight to adults. The technique is as safe as previously reported methods of cerebro-myocardial perfusion and possibly more versatile.

Abstract
One-stage repair of aortic arch obstruction and associated cardiac anomalies is a surgical challenge in infants.The purpose of the present study is to review the current outcome using regional cerebral perfusion (RCP) during a procedure correcting interrupted aortic arch (IAA) and also isolated aortic coarctation (CoA) and CoA combined with hypoplastic aortic arch (CoA-HyAA) in our center. Between January 2007 and July 2008, 24 infant patients with interrupted aortic arch (IAA) (n=3), isolated aortic coarctation (iCoA) (n=9) and aortic coarctation with hypoplastic aortic arch (CoA-HyAA) (n=12) underwent one-stage surgical correction in our hospital. End-to-end anastomosis was employed in 12 infants (IAA n=3 and iCoA n=9); for the other 12 patients with CoA-HyAA, an end-to-end extended anastomosis was used in 8 cases, end-to-side anastomosis in 2 cases, and composite heterologous pericardial patch in 2 cases. RCP with 40 mL/kg/min through the innominate artery during aortic arch reconstruction was employed for all pediatric patients. One single-dose histidine-ketoglutarate-tryptophan (HTK) solution was used for myocardial protection during CPB. Cardiopulmonary bypass time and aortic cross-clamp time were 165.6±32.4min and 81.7±30.0min, respectively. The mean regional cerebral perfusion time was 31.0±10.6min; lowest nasopharyngeal temperature was 19.1±1.1°C. Operative mortality rate in both groups was 8.3%. Mean follow-up was 10.5±4.8 months. There was no late mortality or postoperative neurologic, renal or hepatic complications. All patients are asymptomatic and are developing normally. One-stage total arch repair using the RCP technique is an excellent method that may minimize neurologic and renal complications. Our surgical strategy for arch anomaly has a low rate of residual and recurrent coarctation when performed in these infants.

Abstract
Hypoplastic left heart syndrome is a rare congenital heart defect in which the left side of the heart is underdeveloped. Surgical management of hypoplastic left heart syndrome has changed the prognosis of the condition that was previously regarded as fatal. We discuss surgical strategies based on staged procedures, with the right ventricle supporting both systemic and pulmonary circulation. We also discuss other management options, such as neonatal transplantation and the recent innovation of hybrid techniques. Surgical techniques and the understanding of the pathophysiology of this condition have been at the forefront of neonatal cardiac surgery and intensive care. The management of the syndrome remains a challenge because affected children grow into adolescence and adulthood posing various new problems and demands.

Abstract
The present paper describes the cannulation techniques which are used routinely in our institution. They are established on two basic principles: most operations are performed under full-flow normothermic cardiopulmonary bypass (CPB); deep hypothermic circulatory arrest is avoided. When full-flow conventional CPB is used, cannulation of the ascending aorta and both venae cavae is usually required and should be performed with great caution (with institution of partial bypass as soon as possible) to provide hemodynamic stability during the cannulation process. Additional cannulations and/or technical modifications may be necessary to accommodate frequent associated anomalies (left superior vena cava, systemic or pulmonary venous return anomalies, multiple reoperations). In children requiring aortic arch repair, moderate hypothermia, circulatory arrest and selective cerebral perfusion are used and require specific techniques for arterial cannulation.

J Cardiothorac Surg 2008; 3:58. [PMID: 18973699 PMCID: PMC2583975 DOI: 10.1186/1749-8090-3-58] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2008] [Accepted: 10/31/2008] [Indexed: 11/10/2022] Open
Abstract
Objective We examined the hypothesis that higher cerebral oxygen saturation (rSO2) during RCP is correlated with urinary output. Methods Between December 2002 and August 2006, 12 patients aged 3 to 61 days and weighing 2.6 to 3.4 kg underwent aortic arch repair with RCP. Urinary output and rSO2 were analyzed retrospectively. Data were assigned to either of 2 groups according to their corresponding rSO2: Group A (rSO2 ≦ 75%) and Group B (rSO2 < 75%). Results Seven and 5 patients were assigned to Group A and Group B, respectively. Group A was characterized by mean radial arterial pressure (37.9 ± 9.6 vs 45.8 ± 7.8 mmHg; P = 0.14) and femoral arterial pressure (6.7 ± 6.1 vs 20.8 ± 14.6 mmHg; P = 0.09) compared to Group B. However, higher urinary output during CPB (1.03 ± 1.18 vs 0.10 ± 0.15 ml·kg-1·h-1; P = 0.03). Furthermore our results indicate that a higher dose of Chlorpromazine was used in Group A (2.9 ± 1.4 vs 1.7 ± 1.0 mg/kg; P = 0.03). Conclusion Higher cerebral oxygenation may provide higher urinary output due to higher renal blood flow through collateral circulation.

Abstract
Anomalous origin of coronary arteries is a rare congenital defect and usually presents as an isolated defect. In only 5% of cases, it may be associated with other cardiac anomalies. In this article, we present a case of a newborn with a very complex congenital cardiac disease accompanied with an anomalous origin of an additional coronary artery.

Abstract
Surgical repair of the aortic arch is entailed in the neonatal period of patients with: hypoplastic left heart syndrome, interrupted aortic arch, hypoplastic aortic arch and complex aortic coarctation. Aortic arch surgery requires a period of circulatory arrest and deep hypothermia. Cerebral selective perfusion has recently been introduced as an alternative to circulatory arrest with the aim of reducing mortality and neurological complications. Moreover, the arch reconstruction phase can be safely performed under moderate hypothermia and with cerebral and myocardial perfusion (on beating heart), thus, completely avoiding cerebral ischemia and completely avoiding or drastically reducing myocardial ischemia.
