[PMID: 36268038 PMCID: PMC9576841 DOI: 10.3389/fped.2022.915045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Accepted: 08/26/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Meta-analysis of the impact on clinical outcome from transcatheter closure of Fontan fenestration. METHODS Cochrane, Embase, MEDLINE, and Open-Gray were searched. Parameters such as changes in oxygen saturation, cavo-pulmonary pressure, maximum heart rate during exercise, exercise duration, and oxygen saturation after fenestration closure were pooled and statistical analysis performed. RESULTS Among 922 publications, 12 retrospective observational studies were included. The included studies involved 610 patients, of which 552 patients (90.5%) had a fenestration. Of those patients, 505 patients (91.5%) underwent attempt at trans-catheter closure. When it could be estimated, the pooled overall mean age at trans-catheter fenestration closure was 6.6 ± 7.4 years, and the mean follow-up time was 34.4 ± 10.7 months. There were 32 minor (6.3%) and 20 major (4.0%) complications during or after trans-catheter Fontan fenestration closure. The forest plots demonstrate that following fenestration closure, there was a significant increase in the mean arterial oxygen saturation of 7.9% (95% CI 6.4-9.4%, p < 0.01). There was also a significant increase in the mean cavo-pulmonary pressure of 1.4 mmHg (95% CI 1.0-1.8 mmHg, p < 0.01) following fenestration closure. The exercise parameters reported in 3 studies also favored closing the fenestration as well, yet the exercise duration increase of 1.7 min (95% CI 0.7-2.8 min, p < 0.01) after fenestration closure is probably clinically insignificant. CONCLUSION Late closure of a Fontan fenestration has the impact of improving resting oxygen saturation, exercise oxygen saturation, and a modest improvement of exercise duration. These clinical benefits, however, may be at the expense of tolerating slightly higher cavo-pulmonary mean pressures.

Optimal criteria for transcatheter closure of Fontan fenestration: a single-center experience with a review of literature. Heart Vessels 2021; 36:1246-1255. [PMID: 33590306 DOI: 10.1007/s00380-021-01798-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 01/29/2021] [Indexed: 10/22/2022]
Abstract
Fenestration closure is considered to remove the persistent right-to-left shunt after the Fontan operation. However, the criteria for effective transcatheter closure of fenestration to avoid both acute and chronic Fontan failure have not been clarified. The objective of this study was to describe the hemodynamic data with test occlusion of the Fontan fenestration for patients who underwent a closure and those who did not, along with subsequent development of Fontan-associated diseases (FAD) at follow-up. This was a retrospective study conducted to assess the outcome of Fontan fenestration closure at Children's Hospital of Michigan over 27 years (1993-2019). The inclusion criteria were patients undergoing cardiac catheterization indicated for Fontan fenestration closure. Data were compared between the two groups: closure and non-closure patients. Baseline characteristics and hemodynamic variables with the fenestration occlusion test were analyzed. The primary outcome was the development of composite events of death/transplant, deteriorated New York Heart Association class symptoms, or FAD. Among the 38 patients who were brought to the catheterization laboratory, 33 received fenestration closure and 5 did not. On a median follow-up of 3.4 years (range, 1 month-12.6 years), the incidence of primary adverse outcomes was 13% (5/38). The incidence of primary outcome was significantly higher in the non-closure group (60% vs. 6%, p < 0.01). The non-closure group had a higher incidence of moderate or severe atrioventricular valve regurgitation, New York Heart Association class III symptoms, use of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, furosemide use, and sildenafil use. The multivariable logistic regression model showed that the hemodynamic variables associated with the non-closure group were mean left atrial pressure (odds ratio 1.74, p < 0.05) and change of mean Fontan pressure at the balloon occlusion (odds ratio 2.2, p < 0.05). The judgment of fenestration closure appeared appropriate in our cohort. Fontan fenestration closure may not be advisable in cases with a high baseline left atrial pressure or a significant increase in Fontan pressure on balloon occlusion testing.

Abstract
Venovenous collateral vessels are a common cause for desaturation in patients who have undergone a Fontan procedure. We describe a patient with heterotaxy syndrome (leftward pointing apex) and complex single ventricle with Fontan physiology that was desaturated due to a hepatocardiac vein. The vessel was entered via a left transhepatic access and was successfully occluded using an Amplatzer Vascular Plug.

Late status of Fontan patients with persistent surgical fenestration. J Am Coll Cardiol 2011; 57:2437-43.

Abstract
OBJECTIVES This study was undertaken to determine the effects of creating a systemic-to-pulmonary venous atrial-level communication (fenestration) at the time of the Fontan procedure on late outcomes. BACKGROUND Fenestrations are frequently performed during Fontan procedures, but late consequences are not well described. METHODS Patient characteristics were compared between those with and without surgical fenestration among 536 subjects (mean age 11.9 years) enrolled in the Pediatric Heart Network Fontan Cross-Sectional Study. The status of the fenestration and the association of a currently patent fenestration with health status and measures of ventricular performance were investigated. RESULTS Fenestration was performed in 361 patients (67%), and frequency differed by year and center (p < 0.001 for each). After adjustment for center, age at Fontan, year of Fontan, and prior superior cavopulmonary surgery, the fenestrated group had shorter length of Fontan hospital stay. At the time of cross-sectional testing 8 ± 3 years after Fontan, the fenestration remained open in 19% of subjects. Among those with confirmed fenestration closure, 59% were by catheter intervention and 1% by surgical intervention, and 40% had apparent spontaneous closure. Compared with those without evidence of a fenestration, subjects with a current fenestration were taking more medications (p = 0.02) and had lower resting oxygen saturation (median 89% vs. 95%, p < 0.001). Functional health status, exercise performance, echocardiographic variables, prevalence of post-Fontan stroke or thrombosis, and growth did not differ by current fenestration status. CONCLUSIONS Surgical fenestration is associated with well-demonstrated early post-operative benefits. This cross-sectional study found few associations between a persistent fenestration and deleterious later outcomes.

Abstract
We report our experience in 13 patients who underwent transcatheter closure of Fontan fenestration with the Cook detachable coils. These patients underwent the extracardiac type Fontan operation with a short conduit fenestration (n=7) or lateral tunnel type with a punch-hole fenestration (n=6). Fenestration closure was done at the mean age of 5.1+/-2.4 yr, average of 32 months after the Fontan operation. We used one to three coils depending on the fenestration type, size, and residual shunt. Aortic oxygen saturations increased by an average of 5.4 (2-9)% and mean pressures in the Fontan circuit increased by an average of 2.1 (0-6) mmHg. During follow-up (median of 23 months), five patients (4 in extracardiac, 1 in lateral tunnel) had complete occlusion of the fenestration on echocardiography. There was no immediate or late complication. Transcatheter closure of fenestration in Fontan operation using the Cook detachable coil is a safe and feasible technique. However, the coil was ineffective for closure of a punch-hole fenestration in the lateral tunnel type operation. In the conduit type fenestration, some modification of fenestration method instead of a short conduit for coil closure or use of new device is necessary to increase complete closure rate.

Abstract
A 6-year-old girl with heterotaxy and a functional single ventricle had persistent cyanosis 4 years after a fenestrated Fontan procedure. Cardiac catheterization revealed a large venous fistula from a left-sided hepatic vein to the coronary sinus, resulting in desaturation. The anomalous vein was occluded with an Amplatzer vascular plug.

Abstract
A variety of techniques have been utilized to close Fontan fenestrations. Among 20 patients who underwent a cardiac catheterization for fenestration closure, 3 patients had residual native atrial septum, forming an additional intermediate chamber on the pulmonary venous side of the fenestration. Three different methods were used to close these fenestrations.

Abstract
Apart from closure of atrial septal defects, there is little information concerning the use of the CardioSEAL family of occluders in congenitally malformed hearts. We review here our initial experience using the CardioSEAL and STARFlex occluders in 12 patients aged 17.3 +/- 11.2 years, with a range from 4 to 34 years. Of the patients, 5 had fenestrated extracardiac Fontan procedures, 5 had persistent patency of the arterial duct, 1 had a leak across a Mustard baffle, and the final patient had a huge pulmonary arteriovenous malformation. We implanted successfully 9 CardioSEAL, and 3 STARFlex occluders, with sizes from 17 to 40 mm. In one patient, the occluder embolized to the right pulmonary artery, from where it was retrieved through the catheter. In two patients, there was a trivial residual leak immediately after implantation, but no patient had a residual leak after 6 months of follow-up. We noted improved ventricular dimensions, without any fractures of the arms of the occluders, perforations, or disturbances of flow after 2.4 +/- 0.9 years of follow-up. We have demonstrated, therefore, the versatility of the CardioSEAL and STARFlex occluders, which have been used safely and effectively to close a variety of intra and extracardiac communications other than atrial septal defects.

Abstract
BACKGROUND The Fontan procedure is the definitive operation for palliation of complex congenital heart disease with single-ventricle physiology. Fenestration of the Fontan circuit allows for shunting of deoxygenated blood to the systemic circulation. This procedure improved the clinical outcomes of patients who are at high risk for poor Fontan results. However, it is controversial whether fenestration is beneficial for standard-risk patients. METHODS AND RESULTS This prospective, randomized trial evaluated the clinical utility of fenestration in patients with standard preoperative risk profiles for Fontan surgery. Forty-nine consecutive patients were assigned to undergo either a fenestrated (25 patients) or nonfenestrated (24 patients) Fontan procedure. The fenestrated and nonfenestrated groups were comparable with respect to age (P=0.944), body surface area (P=0.250), number of preoperative risk factors for poor outcome (P=0.681), cardiopulmonary bypass time (P=0.302), number of patients who required aortic cross-clamping (P=0.240), preoperative oxygen saturation (P=0.101), and number of patients with dominant left ventricular morphology (P=0.534). Patients in the fenestrated group had 55% less total chest tube drainage (P=0.036), 41% shorter total hospitalization (P=0.018), and 67% fewer additional procedures in the postoperative period (P=0.006) than those in the nonfenestrated group. CONCLUSIONS Baffle fenestration performed at the time of Fontan surgery improves short-term outcome in standard-risk patients by decreasing pleural drainage, hospital length of stay, and need for additional postoperative procedures.

Abstract
Since diagnostic cardiac catheterization in children with congenital heart disease was first reported in 1947, echocardiography has been used as a non-invasive diagnostic tool in congenital heart disease, resulting in a decrease in diagnostic cardiac catheterizations. However, the total number of cardiac catheterizations remained at a steady level until the mid-1980s and has since increased progressively. This is a result of the introduction of interventional transcatheter techniques to improve or correct congenital heart malformations. Since the first description of balloon atrial septostomy, the range of indications for such techniques has steadily increased, particularly in the past 15 years. 'Deep' sedation or general anaesthesia is essential for the conduct of cardiac catheterization in children, particularly in the younger age group.
