ABSTRACT

Anomalous left coronary artery from the pulmonary artery (ALCAPA) is an uncommon life-threatening congenital heart defect that occurs mostly as an isolated lesion. It is very rarely associated with other cardiac abnormalities. In this report, we present a case of an infant who successfully underwent complete surgical repair of a rare triad of congenital heart defects, including ALCAPA, ventricular septal defect (VSD), and double aortic arch (DAA). To the best of our knowledge, this is only the second case of ALCAPA diagnosis associated with VSD and DAA that has been described in the literature.

ABSTRACT

OBJECTIVES: Surgical repair of complex congenital heart defects with hypoplasia or atresia of the right ventricular outflow tract (RVOT) may require pulmonary valve implantation or replacement during the primary repair or reoperation. The purpose of this study is to evaluate the outcomes of cryopreserved homografts, bovine jugular vein conduits and decellularized Matrix P Plus N conduits in patients undergoing RVOT reconstruction at a single centre. METHODS: Retrospective, single-centre review of 173 patients with 199 conduits undergoing right ventricle-to-pulmonary artery reconstruction with valved conduit from 2002 to 2022. RESULTS: A total of 199 conduits were implanted in 173 patients (62.8% male), with a mean age of 8.97 ± 8.5 years. The following 3 types of conduits were used: homografts 129 (64.8%), bovine jugular vein conduits 45 (22.7%) and Matrix P Plus N 25 (12.5%). During the mean follow-up duration of 8.6 ± 5.8 years, there were 20 deaths, 35 conduit reoperations and 44 catheter reinterventions. Overall survival, reoperation-free and catheter reintervention-free survival at 20 years were 83%, 67.8% and 65.6%, respectively. Multivariable Cox analysis identified younger patient age, smaller conduit size, low patient weight and primary diagnosis of common arterial trunk as risk factors for reoperation and catheter reintervention. CONCLUSIONS: Long-term outcomes of reconstruction of the RVOT using homografts, bovine jugular vein and Matrix P Plus N conduits were acceptable. The reoperation rate for conduit dysfunction did not differ significantly among groups. Over time, the need for conduit replacement was higher in smaller conduits and in patients with common arterial trunk diagnosis.

ABSTRACT

OBJECTIVES:  Repair of congenital heart defects involving right ventricular outflow tract (RVOT) may require pulmonary valve replacement at time of primary repair or reoperation. This study compares the outcomes of cryopreserved homografts with bovine jugular vein conduits (BJVC) in children < 2 years of age with RVOT reconstruction. METHODS:  Retrospective, single-center review of 70 conduits implanted in 63 patients undergoing right ventricle-to-pulmonary artery reconstruction with valved conduit from 2002 to 2022. RESULTS: A total of 70 conduits were implanted in 63 patients, with mean age of 4.5 ± 6.9 months (range 1 day ‒ 23.5 months). The following conduits were used; homografts 38 (54.2 %), BJVC 32 (45.8 %). During mean follow-up of 6.2 ± 5.6 years, there were 12 deaths, 24 conduit reoperations, and 25 catheter reinterventions. Overall survival, reoperation-free, and catheter reintervention-free survival at 15 years was 82.7 %, 31.2 %, and 25.7 %, respectively. Multivariate analysis revealed that low patient weight, age < 30 days at repair, ventilation time, and ICU length of stay were associated with increased risk of death. CONCLUSION: The performance of homografts and BJVC is comparable in patients ent between the two groups (Tab. 3, Fig. 3, Ref. 16).

ABSTRACT

OBJECTIVE: There are several choices for the correction of complex transposition of the great arteries and double outlet right ventricle not amenable to the Rastelli-type surgery, but outcome data are limited to small series. This study aims to report results after the aortic root translocation and en bloc rotation of the outflow tract procedures. METHODS: This is a retrospective, multicentric, observational study. Clinical, anatomy, procedural, and detailed follow-up data (median, 4.43 years) were collected. RESULTS: A total of 70 patients (62.9% male; median age, 1 year; range 4 days to 12.4 years) were included: n = 43 in the aortic root translocation group and n = 27 in the en bloc rotation group. Those in the aortic root translocation group were older (P = .01) and more likely to have had previous procedures (P < .0001), but cardiac anatomy was similar in both groups. Aortic root translocation and en bloc rotation early mortality (30 days) was similar (4.7% vs 3.7%, P = .8). Late survival and freedom from any cardiac reintervention were 92.7% and 16.9% at 15 years overall, respectively. Freedom from right ventricular outflow tract/conduit reintervention was better in the en bloc rotation group than in the aortic root translocation group (100% vs 24.5%, P = .0003), but more patients in the en bloc rotation group had moderate (or worse) aortic valve regurgitation during follow-up (16% vs 2.6%, P = .07). CONCLUSIONS: Both aortic root translocation and en bloc rotation are valuable surgical options for the treatment of complex transposition of the great arteries and double outlet right ventricle. In the en bloc rotation group, there was better freedom from right ventricular outflow tract reinterventions, but a higher probability of aortic valve regurgitation. Identifying the main driving forces for these observed differences requires further study of these procedures.

ABSTRACT

Lamellar (Pacinian) corpuscle is a cutaneous encapsulated sensory corpuscle, mainly functioning as a rapidly adapting low-threshold mechanoreceptor with characteristic "onion skin"-like appearance. Even though the Pacinian corpuscle is typically located in the skin, histomorphologically and confirmed by using immunohistochemical methods, we have identified it within the interstitium of the thymus of a newborn with congenital heart defect. To the best of our knowledge, this is the first such account ever to be published. The structure of the thymic Pacinian corpuscle was the same as the Pacinian corpuscle in the skin. The ectopic thymic Pacinian corpuscle can be hypothetically explained as the consequence of impaired migration of neural crest cells, since neural crest-derived cells play an important role in the development of the Pacinian corpuscle, as well as the thymus and heart. In general, the occurrence of ectopic Pacinian corpuscle in different organs is rare. In the scientific literature, there are reports of its sporadic presence in the pancreas, in the lymph nodes, inside the prostate and the urinary bladder wall. Our report presents the first described case of the Pacinian corpuscle in a heterotopic location in the thymus. Similar to other incidental findings of this anatomic structure, explanation of its ectopic development, as well as its local function remains only speculative.

ABSTRACT

Aorto-ventricular tunnel (AoVT), a rare congenital anomaly, is a channel originating in the ascending aorta just above the sinotubular junction and leading to the cavity of the left ventricle (AoLVT), or, rarely, the right (AoRVT). This study reviews our collective 30-year experience with the surgical treatment of AoVT. Data were submitted by 15 participating centers on 42 patients who underwent correction of AoVT between 1987 and 2018. Of these, 36 had AoLVT, and 6 AoRVT. The tunnel originated above the right coronary sinus in 28 (77.8%) patients. For AoLVT, most operations were performed early (median age 25 days, range: 1 day-25 years). In contrast, AoRVT was diagnosed and repaired later (median age 6 years, range: 1 month-12 years). Surgically important coronary ostial displacement was common. Patch closure of the aortic orifice only was the commonest surgical repair for AoLVT (23 patients), while in AoRVT, both orifices or only the ventricular one was closed. Aortic valvar insufficiency, severe or moderate, coexisted in 11 (30.5%) patients with AoLVT, and aortic valvuloplasty was performed in 8, mainly due to aortic valve stenosis. Aortic valvar insufficiency at discharge ranged from trivial to mild in almost all patients. Early mortality was 7.14%, with 3 patients with AoLVT succumbing to cardiac failure. There were 2 early reoperations and 1 late death. AoVT is a rare malformation. AoLVT usually necessitates surgery in early life. AoRVT is rarer, diagnosed and repaired later in life. Surgical repair by patch closure, with concomitant aortic valve repair as needed, is associated with good results.

ABSTRACT

OBJECTIVES: We sought to describe early and late outcomes in a large surgical series of patients with anomalous aortic origin of coronary arteries. METHODS: We performed a retrospective multicentre study including surgical patients with anomalous aortic origin of coronary arteries since 1991. Patients with isolated high coronary takeoff and associated major congenital heart disease were excluded. RESULTS: We collected 156 surgical patients (median age 39.5 years, interquartile range 15-53) affected by anomalous right (67.9%), anomalous left (22.4%) and other anatomical abnormalities (9.6%). An interarterial course occurred in 86.5%, an intramural course in 62.8% and symptoms in 85.9%. The operations included coronary unroofing (56.4%), reimplantation (19.2%), coronary bypass graft (15.4%) and other (9.0%). Two patients with preoperative cardiac failure died postoperatively (1.3%). All survivors were discharged home in good clinical condition. At a median follow-up of 2 years (interquartile range 1-5, 88.5% complete), there were 3 deaths (2.2%), 9 reinterventions in 8 patients (5 interventional, 3 surgical); 91.2% are in New York Heart Association functional class ≤ II, but symptoms persisted in 14.2%; 48.1% of them returned to sport activity. On Kaplan-Meier analysis, event-free survival at follow-up was 74.6%. Morbidity was not significantly different among age classes, anatomical variants and types of surgical procedures. Furthermore, return to sport activity was significantly higher in younger patients who participated in sports preoperatively. CONCLUSIONS: Surgical repair of anomalous aortic origin of coronary arteries is effective and has few complications. Unroofing and coronary reimplantation are safe and are the most common procedures. The occurrence of late adverse events is not negligible, and long-term surveillance is mandatory. Most young athletes can return to an unrestrained lifestyle.

ABSTRACT

BACKGROUND: Anomalous aortic origin of coronary arteries (AAOCA) is a rare abnormality, whose optimal management is still undefined. We describe early outcomes in patients treated with different management strategies. METHODS: This is a retrospective clinical multicenter study including patients with AAOCA, undergoing or not surgical treatment. Patients with isolated high coronary take off and associated major congenital heart disease were excluded. Preoperative, intraoperative, anatomical and postoperative data were retrieved from a common database. RESULTS: Among 217 patients, 156 underwent Surgical repair (median age 39 years, IQR: 15-53), while 61 were Medical (median age 15 years, IQR: 8-52), in whom AAOCA was incidentally diagnosed during screening or clinical evaluations. Surgical patients were more often symptomatic when compared to medical ones (87.2% vs 44.3%, p < 0.001). Coronary unroofing was the most frequent procedure (56.4%). Operative mortality was 1.3% (2 patients with preoperative severe heart failure). At a median follow up of 18 months (range 0.1-23 years), 89.9% of survivors are in NYHA ≤ II, while only 3 elderly surgical patients died late. Return to sport activity was significantly higher in Surgical patients (48.1% vs 18.2%, p < 0.001). CONCLUSIONS: Surgery for AAOCA is safe and with low morbidity. When compared to Medical patients, who remain on exercise restriction and medical therapy, surgical patients have a benefit in terms of symptoms and return to normal life. Since the long term-risk of sudden cardiac death is still unknown, we currently recommend accurate long term surveillance in all patients with AAOCA.

ABSTRACT

BACKGROUND: The optimal management and prognostic factors of postsurgical pulmonary vein stenosis remain controversial. We sought to determine current postsurgical pulmonary vein stenosis outcomes and prognostic factors in a multicentric study in the current era. METHODS: Seventy-five patients with postsurgical pulmonary vein stenosis who underwent 103 procedures in 14 European/North American centers (2000-2012) were included retrospectively. A specific pulmonary vein stenosis severity score was developed on the basis of the assessment of each pulmonary vein. End points were death, pulmonary vein reintervention, and restenosis. A univariate and multivariate risk analysis was performed. RESULTS: Some 76% of postsurgical pulmonary vein stenosis occurred after repair of a total anomalous pulmonary venous return. Sutureless repair was used in 42 of 103 procedures (41%), patch veinoplasty was used in 28 procedures (27%), and endarterectomy was used in 16 procedures (16%). Overall pulmonary vein restenosis, reintervention, and mortality occurred in 56% (n = 58/103), 49% (n = 50/103), and 27% (n = 20/75), respectively. Sutureless repair was associated with less restenosis (40% vs 67%; P = .007) and less reintervention (31% vs 61%; P = .003). Mortality after sutureless repair (20%; 7/35) tends to be lower than after nonsutureless repair (33%; 13/40) (P = .22). A high postoperative residual pulmonary vein stenosis score at the time of hospital discharge was an independent risk factor for restenosis (hazard ratio [HR], 1.55; P < 10-4), reintervention (HR, 1.33; P < 10-4), and mortality (HR, 1.37; P < 10-4). The sutureless technique was an independent protective factor against restenosis (HR, 0.27; P = .006). CONCLUSIONS: Postsurgical pulmonary vein stenosis still has a guarded prognosis in the current era. The sutureless technique is an independent protective factor against restenosis. The severity of the residual disease evaluated by a new severity score is an independent risk factor for poor outcomes regardless of surgical technique.

ABSTRACT

OBJECTIVES: Our goal was to evaluate the early and late results of the surgical management of congenital supravalvular aortic stenosis (SVAS). METHODS: We performed a retrospective, multicentre study using data from the European Congenital Heart Surgeons Association. Exclusion criteria were age >18 years, operation before 1990 and redo supravalvular aortic stenosis operations. Multivariate Cox regression analysis was performed to detect independent predictors of adverse events. RESULTS: Of a total of 301 patients (male/female = 194/107; median age 3.9 years, range 13 days-17.9 years), 17.6% had a prior surgical or interventional procedure. Pulmonary artery stenosis was present in 41.5% and coronary anomalies in 13.6%. The operation consisted of a single patch repair in 36.7%, a pantaloon-shaped patch in 36.7%, a 3-patch technique in 14.3% and other techniques in 11.7%. Postoperative complications occurred in 14.9%, and the early mortality rate was 5%. At a median follow-up of 13 years (interquartile range 3.5-7.8; follow-up completed 79.1%), there were 10 late deaths (4.2%). A surgical reoperation or an interventional cardiology procedure occurred in 12.6% and 7.2%, respectively. No significant differences in outcomes between the techniques were found. Age at repair <12 months and pulmonary artery stenosis were associated with an increased risk of early (P = 0.0001) and overall mortality (P = 0.025), respectively. Having an operation after 2005 and co-existing pulmonary artery stenosis were significant predictors of late reintervention (P = 0.0110 and P = 0.001, respectively). CONCLUSIONS: Surgical repair of congenital stenosis is an effective procedure with acceptable surgical risk and good late survival, but late morbidity is not negligible, especially in infants and when associated pulmonary artery stenosis is present.

ABSTRACT

BACKGROUND: We sought to report the frequency, types, and outcomes of left-sided reoperations (LSRs) after an arterial switch operation (ASO) for patients with D-transposition of the great arteries (D-TGA) and double-outlet right ventricle (DORV) TGA-type. METHODS: Seventeen centers belonging to the European Congenital Heart Surgeons Association (ECHSA) contributed to data collection. We included 111 patients who underwent LSRs after 7,951 ASOs (1.4%) between January 1975 and December 2010. Original diagnoses included D-TGA (n = 99) and DORV TGA-type (n = 12). Main indications for LSR were neoaortic valve insufficiency (n = 52 [47%]) and coronary artery problems (CAPs) (n = 21 [19%]). RESULTS: Median age at reoperation was 8.2 years (interquartile range [IQR], 2.9-14 years). Seven patients died early after LSRs (6.3%); 4 patients with D-TGA (5.9%) and 3 patients with DORV TGA-type (25%) (p = 0.02). Median age at last follow-up was 16.1 years (IQR, 9.9-21.8 years). Seventeen patients (16%) required another reoperation, which was more frequent in patients with DORV- TGA type (4 of 9 [45%]) than in patients with D-TGA (13 of 95 [14%]). Late death occurred in 4 patients (4 of 104 [3.8%]). The majority of survivors were asymptomatic at last clinical examination (84 of 100 [84%]). CONCLUSIONS: Reoperations for residual LSRs are infrequent but may become necessary late after an ASO, predominantly for neoaortic valve insufficiency and CAPs. Risk at reoperation is not negligible, and DORV TGA-type anatomy, as well as procedures on the coronary arteries, were significantly associated with a higher morbidity and a lower overall survival. Recurrent reoperations after LSRs may be required.

ABSTRACT

BACKGROUND: Primary pulmonary vein stenosis (PPVS) still carries a poor prognosis, and prognostic factors remain controversial. The aim of this study was to determine outcomes and prognostic factors after PPVS repair in the current era. METHODS: Thirty patients with PPVS and a normal pulmonary vein (PV) connection operated on in 10 European/North American centers (2000-2012) were included retrospectively. A specific PVS severity score was developed based on the assessment of each PV. Studied end points were death, PV reoperation, and restenosis. A univariate and multivariate risk analysis was performed. RESULTS: The mean number of affected PVs per patient was 2.7 ± 1.1. Sutureless repair was used in 21 patients (70%), endovenectomy was used in 5 patients, and patch venoplasty was used in 4 patients. Overall PV restenosis, reoperation, and mortality occurred in 50%, 40%, and 30% of patients respectively. Freedom from mortality, reoperation, and restenosis at 8 years of follow-up was 70% ± 8%, 62% ± 8%, and 47% ± 9%, respectively. Restenosis and mortality rates after sutureless repair versus nonsutureless repair were 57% (n = 12 of 21) versus 33% (n = 3 of 9) (p = 0.42) for restenosis and 38% (n = 8 of 21) versus 11% (n = 1 of 9) (p = 0.21) for mortality. Patients selected for a sutureless technique were younger and smaller and had more severe disease before operation. A postoperative high PVS score and pulmonary hypertension 1 month after the operation were independent risk factors for restenosis (hazard ratio [HR], 1.34; p = 0.002 and HR, 6.81; p = 0.02, respectively), reoperation (HR, 1.24; p = 0.01 and HR, 7.60; p = 0.02), and mortality (HR, 1.39; p = 0.01 and HR, 39.5; p = 0.008). CONCLUSIONS: Primary PVS still has a guarded prognosis in the current era despite adoption of the sutureless technique. Postoperative pulmonary hypertension and severity of disease evaluated by a new severity score are independent prognostic factors regardless of surgical technique.

ABSTRACT

BACKGROUND AND AIM: To evaluate the accuracy of the three-dimensional (3D) printing of cardiovascular structures. To explore whether utilisation of 3D printed heart replicas can improve surgical and catheter interventional planning in patients with complex congenital heart defects. METHODS: Between December 2014 and November 2015 we fabricated eight cardiovascular models based on computed tomography data in patients with complex spatial anatomical relationships of cardiovascular structures. A Bland-Altman analysis was used to assess the accuracy of 3D printing by comparing dimension measurements at analogous anatomical locations between the printed models and digital imagery data, as well as between printed models and in vivo surgical findings. The contribution of 3D printed heart models for perioperative planning improvement was evaluated in the four most representative patients. RESULTS: Bland-Altman analysis confirmed the high accuracy of 3D cardiovascular printing. Each printed model offered an improved spatial anatomical orientation of cardiovascular structures. CONCLUSIONS: Current 3D printers can produce authentic copies of patients` cardiovascular systems from computed tomography data. The use of 3D printed models can facilitate surgical or catheter interventional procedures in patients with complex congenital heart defects due to better preoperative planning and intraoperative orientation.

ABSTRACT

OBJECTIVE: The objective of this European multicenter study was to report surgical outcomes of Fontan takedown, Fontan conversion and heart transplantation (HTX) for failing Fontan patients in terms of all-cause mortality and (re-)HTX. METHODS: A retrospective international study was conducted by the European Congenital Heart Surgeons Association among 22 member centres. Outcome of surgery to address failing Fontan was collected in 225 patients among which were patients with Fontan takedown (n=38; 17%), Fontan conversion (n=137; 61%) or HTX (n=50; 22%). RESULTS: The most prevalent indication for failing Fontan surgery was arrhythmia (43.6%), but indications differed across the surgical groups (p<0.001). Fontan takedown was mostly performed in the early postoperative phase after Fontan completion, while Fontan conversion and HTX were mainly treatment options for late failure. Early (30 days) mortality was high for Fontan takedown (ie, 26%). Median follow-up was 5.9 years (range 0-23.7 years). The combined end point mortality/HTX was reached in 44.7% of the Fontan takedown patients, in 26.3% of the Fontan conversion patients and in 34.0% of the HTX patients, respectively (log rank p=0.08). Survival analysis showed no difference between Fontan conversion and HTX (p=0.13), but their ventricular function differed significantly. In patients who underwent Fontan conversion or HTX ventricular systolic dysfunction appeared to be the strongest predictor of mortality or (re-)HTX. Patients with valveless atriopulmonary connection (APC) take more advantage of Fontan conversion than patients with a valve-containing APC (p=0.04). CONCLUSIONS: Takedown surgery for failing Fontan is mostly performed in the early postoperative phase, with a high risk of mortality. There is no difference in survival after Fontan conversion or HTX.

ABSTRACT

OBJECTIVES: The purpose of this study is to evaluate our initial experience with aortic valve repair using polytetraflouroethylene (PTFE) leaflet extensions in congenital valvular disease. METHODS: From October 2008 through February 2011, 13 patients underwent aortic valvuloplasty by PTFE leaflet extensions. All valves were repaired in a tri-leaflet configuration using PTFE leaflet extensions. The median age at operation was 14 years (1.8-19.7 years) and the median weight was 58 kg (9.5-86 kg). Previous interventions included balloon valvuloplasty in two patients, aortic valvuloplasty in one and coarctation repair in one patient. Eight (73%) patients had combined aortic stenosis and insufficiency, three (23%) had isolated insufficiency and two (15%) had stenosis only. In 10 (77%) patients, a bicuspid aortic valve was present. RESULTS: The follow-up ranged from 2 to 30 months (mean follow-up 14.8 ± 9 months). At the latest echocardiography follow-up, six patients had none or trace aortic insufficiency, six patients had a mild aortic insufficiency and one patient had a mild-to-moderate insufficiency. The mean aortic insufficiency degree decreased from 1.8 ± 1.2 preoperatively to 0.8 ± 0.6 at the follow-up (P < 0.01). The mean gradient across the aortic valve decreased from 56 ± 40 mmHg preoperatively to 12 ± 13 mmHg at the follow-up (P < 0.0008). All patients are alive. There were no reoperations. The median hospital stay was 9 days (4-21 days). CONCLUSIONS: The use of PTFE leaflet extensions is an effective technique for aortic valve reconstruction in congenital valvular disease. Long-term follow-up is necessary to assess the durability of this type of repair.

ABSTRACT

BACKGROUND: The question of whether to close the patent ductus arteriosus when performing primary modified Blalock-Taussig (MBT) shunt surgery in neonates is still not clearly answered. The aim of this report was to compare the results of closure versus nonclosure of the patent ductus arteriosus during MBT shunt surgery in neonates with pulmonary atresia. METHODS: This retrospective study included neonates with pulmonary atresia who underwent primary MBT shunt surgery through a sternotomy approach at our institution between January 1997 and October 2010. Mortality, resuscitation events, and the need for reintervention within the first 48 postoperative hours were studied as primary outcomes. RESULTS: Sixty-two neonates (mean age 6.9±5.5 days) underwent a MBT procedure. The arterial duct was closed surgically in 31 patients, and left open in 31 patients. Compared with patients in whom the PDA was left open, patients with a surgically closed arterial duct had a higher incidence of resuscitation events (29.0% versus 0%, p=0.0012), reinterventions (35.5% versus 3.2%, p=0.0013), and higher early hospital mortality (9.7% versus 0%, p=0.038). Time to extubation and length of hospital stay did not differ between the two groups (p=0.16 and p=0.73, respectively). A trend toward a higher maximum vasoactive-inotropic score in the group with a closed duct was observed (median 13.5 versus 10, p=0.10). CONCLUSIONS: In newborns with pulmonary atresia, ductal closure during MBT shunt procedure is associated with increased incidence of resuscitation events, need for reintervention, and increased mortality during the early postoperative period.

ABSTRACT

Anomalous origin of the left coronary artery from the right pulmonary artery in association with hypoplastic left heart syndrome is a rare congenital anomaly. We describe a successful simultaneous surgery for both anomalies during the first stage palliation in a neonate.
