ABSTRACT

Objective: We reviewed our experience with transvenous liver biopsy-derived hepatic fibrosis scores and possible associated risk factors in those postextracardiac Fontan patients. Methods: We identified extracardiac-Fontan patients with postoperative durations <20 years who underwent cardiac catheterizations with transvenous hepatic biopsies between April 2012 and July 2022. If a patient underwent two liver biopsies, we averaged the two total fibrosis scores and concurrent time, pressure, and oxygen saturation data. We grouped patients by the following factors: (1) sex, (2) venovenous collaterals, and (3) type of functionally univentricular heart. We identified potential hepatic fibrosis risk factors as the following: female, presence of venovenous collaterals, and a functional univentricle of right-ventricular type. For statistical analysis, we used Kruskal-Wallis nonparametric testing. Results: We identified 127 patients who underwent 165 transvenous biopsies, with 38 patients undergoing 2 biopsies. We found that females with two additional risk factors had the highest median total fibrosis scores, 4 (1-8); males with <2 risk factors had the lowest median total fibrosis scores, 2 (0-5); and females with <2 additional risk factors and males with two risk factors were in the middle, median total fibrosis score 3 (0-6), P =.002; and there were no statistical differences for the other demographic or hemodynamic variables. Conclusions: For extracardiac-Fontan patients with similar demographic and hemodynamic variables, identifiable risk factors are associated with the degree of hepatic fibrosis.

ABSTRACT

OBJECTIVE: We investigated the prevalence of isolated vascular rings in the general population of Southern Nevada. METHODS: We identified those prenatally and postnatally diagnosed with an isolated vascular ring between January 2014 and December 2021. We included only those with vascular or ligamentous structures completely encircling the trachea and esophagus. To investigate the prevalence of isolated vascular rings, we included only those with situs solitus, levocardia, and no significant intracardiac malformations. RESULTS: We identified 112 patients. Of the 112, 66 (59%) were female. There were approximately 211,000 total live births in Southern Nevada for the study period, for an overall prevalence of 5.3 isolated vascular rings per 10 000 live births. However, for the years 2014 to 2017, the average prevalence figure was 3.5 per 10 000 live births, and for the years 2018 to 2021, the average prevalence figure was 7.1 (range 6.5-8.0) per 10 000 live births. Simultaneously, the prenatal detection rate rose from 66% to 86%. CONCLUSIONS: Isolated vascular rings are common cardiovascular malformations. As prenatal detection rates in the Southern Nevada general population approach 90%, the prevalence figures for isolated vascular rings appear to asymptote at about 7 per 10 000 live births.

ABSTRACT

We analyzed patients with isolated, balanced complete atrioventricular septal defects. We identified 71 patients born in Nevada, between January 2008 and December 2020. We also analyzed prenatal detection rates. Of the 71, 61 (85%) had trisomy 21, 1 (1%) had CHARGE syndrome and 22q.11 deletion, and 10 (14%) had no chromosomal abnormalities. Of the 71, 67 had prenatal care, and 43/67 (64%) were prenatally diagnosed. Prenatal detection rate for 2008-2012 was 9/20 (45%) and 18/21 (86%) for 2018-2020, P = .03. Of the 71, 67 underwent surgical repair with 1 current postpulmonary artery banding and 0 surgical deaths. Of the 67, 3 (4%) had heart block. Only 1 (1.5%) patient had reoperation for a mitral valve replacement. Of the 71, 67 (94%) are alive during a 6-year average (range = 0-12 years) follow-up. In conclusion, surgical and long-term outcomes were excellent. Also, high state-wide, general population prenatal detection rates were achieved.

ABSTRACT

OBJECTIVE: We reviewed our center's experience with neonatal and infant hypoplastic aortic arch, unassociated with intracardiac malformations, and investigated changes in prenatal detection rates over time for those requiring therapeutic procedures. METHODS: We identified all prenatal diagnoses of hypoplastic aortic arch with situs solitus, unassociated with intracardiac malformations, made in Nevada between May 2017 and April 2022. In addition, we identified all those 0-180 days old, with prenatal care, that underwent a surgical or interventional cardiac catheterization aortic arch procedure, whether prenatally or postnatally diagnosed. We excluded those with ventricular septal defects, functionally univentricular hearts, interrupted aortic arches, or any associated malformation requiring an additional surgical or interventional procedure ≤6 months old. Additionally, we calculated prenatal detection rates for those undergoing a surgical or interventional catheterization procedure for each of the 5 years. RESULTS: We identified 107 patients prenatally and postnatally. Of the 107 patients, 56 (34 prenatally diagnosed and 22 postnatally diagnosed) underwent an aortic arch procedure, and 51 additionally prenatally diagnosed, live-born infants did not undergo a procedure. Of the 56 procedures, 2 were by interventional catheterization, and 54 underwent a surgical repair. Prenatal detection for those undergoing a procedure statistically significantly increased over the 5 years from 38% to 82%, rho = 0.95 (p = .04). CONCLUSIONS: Currently in Nevada, our prenatal detection rate is >80% in the general population for those between 0 and 6 months old who require a therapeutic procedure for aortic arch obstruction without intracardiac malformations.

ABSTRACT

OBJECTIVE: We reviewed our center's surgical mortality rates for those who underwent a Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) category 4 or 5 neonatal cardiovascular surgery. METHODS: We identified all patients who underwent a STAT category 4 or 5 neonatal index cardiovascular surgical procedure between July 2015 and July 2021. RESULTS: We identified 239 patients. We divided them into two groups: (1) 42 (17.6%) ≤2.5 kg, and (2) 197 (82.4%) were >2.5 kg at the time of neonatal surgery. Of those ≤2.5 kg, 18/42 (42.9%) had syndromes or associated noncardiac malformations versus 34/197 (17.3%) of those >2.5 kg, p = .0093. Thirty-day discharge mortality for those ≤2.5 kg was 3/42 (7.1%) versus l0/197 (5.1%) for those >2.5 kg, p = .83. CONCLUSIONS: Weight at the time of surgery, presence of syndromes, and associated noncardiac malformations did not affect mortality in those undergoing complex neonatal STAT 4 or 5 category cardiovascular surgery.

ABSTRACT

Objective: Our objective was to investigate whether a relationship existed between our center's STAT 4 and 5 category surgical mortality and general-population prenatal detection rates in Nevada. Methods: We identified patients who underwent STAT 4 and 5 neonatal index cardiovascular surgeries at our center between October 2012 and September 2021. Additionally, we calculated prenatal detection rates for each of the 9 retrospective study years. We used descriptive statistics and nonparametric testing, including the Spearman Rho correlation (R) and the Mann-Whitney U-tests, with a significant P-value set at < .05. Results: We identified 356 patients. We noted a statistically significant increasing trend in prenatal detection percentages (rho = 0.79, P = .01), concurrent with a statistically significant decreasing trend in surgical mortality (rho = -0.82, P = .007). Conclusions: Despite encouraging results, we could not establish a cause-and-effect relationship between concurrent decreased surgical mortality and increased prenatal detection rates for patients undergoing STAT 4 and 5 surgical procedures at our center.

ABSTRACT

OBJECTIVE: We retrospectively analyzed our center's experience with the prenatal diagnosis of isolated perimembranous ventricular septal defects that underwent primary surgical repair in infancy. METHODS: We identified patients born in Southern Nevada, between October 2012 and October 2020, with prenatal care that underwent surgical closure of an isolated large perimembranous ventricular septal defect between 1 and 12 months of age. The description at surgery defined ventricular septal defect morphology. We included only those with situs solitus, levocardia without dextroposition, and without any other cardiovascular abnormality. We analyzed prenatal detection rates for each of the eight years. RESULTS: We identified 81 patients. Of the 81, 35 (43%) had trisomy 21. We identified no other aneuploidies in those that underwent surgical repair; however, 1 had a 15q13.3 deletion syndrome, and 1 had a 22 q11.2 deletion syndrome. Of the 81, 27 (33%) overall were prenatally diagnosed. Increasing prenatal detection rates strongly correlated with time (R = 0.92, p = .002). CONCLUSIONS: Trisomy 21 is common in isolated perimembranous ventricular septal defects undergoing primary repair in infancy. Further, prenatal detection rates significantly improved over time, up to 65% detection in the current years.

ABSTRACT

OBJECTIVE: We reviewed our center's prenatal detection and surgical experience with high-risk, 2-ventricle patients, with complex congenital heart disease that underwent stage-1 hybrid palliation. METHODS: We retrospectively identified those born between March 2008 and March 2021 with 2-ventricle hearts, complex congenital cardiovascular malformations, and ductal-dependent systemic circulation that underwent stage-1 hybrid palliation consisting of surgical bilateral pulmonary artery banding and interventional catheterization placed ductus arteriosus stents. RESULTS: We identified 30 patients. Of the 30, 19 (63%) were male. For the 30, median gestational age was 35 weeks (29-39 weeks), and median birth weight was 2.2 kg (0.6-4.5 kg). Of the 30, 1 was transferred from an adjacent state, and 29 were born in Nevada. Of the 29 born in Nevada, overall statewide prenatal detection was 18 of 29 (62%); however, for 2008 to 2011 the prenatal detection rate was 3 of 10 (30%) and 15 of 19 (79%) for 2012 to 2021, P = .03. For the last 5 years, prenatal detection for Nevada-born patients was 8 of 8 (100%). Two full-term newborns, without a prenatal diagnosis, presented postnatally in extremis. For the 30 patients, there were 0 stage-1 hybrid palliation mortalities, 1 subsequent repair mortality, and 3 late nonsurgical deaths. CONCLUSIONS: Stage-1 hybrid palliation may result in excellent surgical outcomes for high-risk, 2-ventricle patients. Additionally, high rates of population-wide prenatal detection are possible for high-risk congenital heart disease, allowing prenatal planning and possibly reducing postnatal extremis presentations.

ABSTRACT

OBJECTIVE: We reviewed our center's experience with prenatal detection in Nevada's general population for young infants undergoing cardiovascular surgery. METHODS: We identified patients born in Nevada that underwent an initial cardiovascular surgery between 0 and 6 months old with birth dates between August 2012 and July 2021. Additionally, we calculated prenatal congenital cardiovascular malformation detection rates for each of the 9 years. RESULTS: We identified 660 patients. For the 660 patients, 649 (98%) mothers underwent prenatal care, which included at least one anatomical-survey obstetric ultrasound. Of the 649 with prenatal care, 395 (61%) had a prenatal diagnosis overall. However, prenatal diagnosis improved over the 9 years from 44% in 2012 to 79% in 2021 (correlation coefficient of 0.93, p = .00024). CONCLUSIONS: Our results demonstrated a progressive rise in prenatal detection rates for young infants undergoing cardiovascular surgery in Nevada.

ABSTRACT

OBJECTIVE: We reviewed our center's experience with common arterial trunk. METHODS: We included those with common arterial trunk in Nevada with estimated delivery dates or birth dates between June 2006 and May 2021. We excluded patients with functionally univentricular hearts. RESULTS: We identified a total of 39: 32 prenatally and 7 postnatally. Of the 32 prenatally detected, 2 had elective termination, 2 had fetal demise, and 28 were live-born. Of the 7 postnatally diagnosed, 6 had prenatal care without a fetal echocardiogram, and 1 had no prenatal care. Overall, live-born prenatal detection was 28/34 (82%). Prenatal detection for 2006-2009 was 2/6 (33%) and for 2010-2021 was 26/28 (93%) p = .049. Of the 35 live-born infants, 1 died preoperatively, and 34 underwent neonatal surgery. Of the 34, 8 had palliation (birth weight 1.9±0.7 kg, range 0.8-2.6 kg), and 26 had a primary repair (birth weight 3.0±0.3 kg, range 2.6-4.0 kg) p = .0004. For all 34 neonatal surgical procedures, there were 2 (5.9%) deaths; however, there were no subsequent surgical or interventional catheterization mortalities. CONCLUSIONS: In Nevada, current state-wide, general population prenatal detection of the common arterial trunk was more than 90%. By employing a combination of neonatal palliation and primary repair, surgical mortality was less than 6% in a cohort that included those with birth weights less than 2.5 kg, truncal valve surgery, and interrupted aortic arches.

ABSTRACT

OBJECTIVE: We investigated a relationship between a composite index comprised of Fontan-circuit anatomical features and hepatic fibrosis scores from biopsy. METHODS: We identified living extracardiac Fontan patients, ≥7 years old and ≥5 but <20 years postoperative, that underwent cardiac catheterization and transvenous liver biopsy between March 2012 and September 2020. We divided patients into anatomical groups and applied a risk score to each patient. We compared average anatomical risk scores with average hepatic total fibrosis scores by group. RESULTS: We identified 111 patients that met inclusion criteria. After excluding four patients, we assigned 107 to one of 12 anatomical variant groups (n ≥ 3). For the 107, the average age at liver biopsy was 14 ± 6 years old. Of the 107, 105 (98%) were New York Heart Association Class 1. We found average anatomical risk scores by group correlated with average total fibrosis scores by group (R = 0.8; p = .005). An average Fontan duration to biopsy of 10 ± 1 years was similar for all 12 anatomical groups. We found no other clinical variables, laboratory, or hemodynamic values that trended with anatomical risk scores or hepatic total fibrosis scores. CONCLUSIONS: In a cohort of relatively young, stable extracardiac Fontan patients, average composite anatomical risk scores strongly correlated with average hepatic total fibrosis scores by anatomical group. These findings suggest that some anatomical variants in extracardiac Fontan patients are associated with higher Fontan-associated liver disease (FALD)-related hepatic total fibrosis scores than others, despite similar Fontan durations.

ABSTRACT

OBJECTIVE: We hypothesized that a relationship between post-Fontan hepatic fibrosis and anatomical variants might exist. METHODS: Attempting to limit confounding variables, we analyzed data from living, stable, post-extracardiac Fontan patients who underwent cardiac catheterization and transvenous hepatic biopsy procedures between March 2012 and June 2020. RESULTS: We identified 120 patients who met the inclusion criteria. Of the 120, 35 (29%) had pulmonary artery stents. For the 35 with pulmonary artery stents, the average total fibrosis score was 3.2 ± 1.9 and the fibrosis progression rate was 0.36 ± 0.33, and for those with no pulmonary artery stents, the total fibrosis score was 2.6 ± 1.8 and the fibrosis progression rate was 0.27 ± 0.33 (P = .13 and P = .11, respectively). Of the 120, 65 had functional univentricles of right ventricular type. Of these 65, 27 had pulmonary artery stents. For the 27 with pulmonary artery stents, the average total fibrosis score was 3.4 ± 1.8 and the average fibrosis progression rate was 0.39 ± 0.30, and for the 38 without pulmonary artery stents, the average fibrosis score was 2.3 ± 1.5 and the average fibrosis progression rate was 0.23 ± 0.21 (P = .01 for comparison of both values). CONCLUSIONS: This study's findings suggest that a post-extracardiac Fontan with a functional univentricle of right ventricular type plus a pulmonary artery stent may have more advanced liver pathology than those without a pulmonary artery stent at similar Fontan duration years and ages at liver biopsy.

ABSTRACT

OBJECTIVE: We reviewed our center's isolated vascular ring data. METHODS: Inclusion criteria were patients born in Nevada between June 2015 and July 2020 with situs solitus, levocardia, atrioventricular and ventriculoarterial concordance, and no significant intracardiac malformations. RESULTS: We identified 95 patients. Of the 95, 56 (59%) were female (p = .033). For the study period, there were approximately 180,000 live births, for a prevalence of 5.3 isolated vascular rings per 10,000 live births. Of the 95, 78 (82%) were prenatally diagnosed. Of the 95, 63 (66%) were products of high-risk pregnancies (p = .0001). Additionally, we found advanced maternal age was an isolated vascular ring risk factor (relative risk ratio, 2.7; 95% confidence interval, 1.8, 4.1; p < .00001). CONCLUSIONS: Isolated vascular rings are relatively common cardiovascular malformations and more common in females. High prenatal detection rates are achievable. Further, the majority with isolated vascular rings are products of high-risk pregnancies, and advanced maternal age is a statistically significant occurrence risk factor.

ABSTRACT

OBJECTIVE: We hypothesized that a relationship might exist between angiographically demonstrable, post-Fontan venovenous collaterals, and hepatic fibrosis. METHODS: We analyzed data from post-Fontan patients that underwent cardiac catheterization and transvenous-hepatic biopsy procedures between March 2012 and March 2020. From innominate vein angiography, we determined those that either had or lacked venovenous collaterals. Additionally, we examined data from post-Fontan patients that underwent hepatic ultrasound, shear-wave elastography between January 2017 and March 2020. RESULTS: We identified 164 patients that met inclusion criteria. Of the 164, 101 (62%) had venovenous collaterals. Of the 101 with collaterals, average total fibrosis score (TFS) was 3.2 and the average rate of fibrosis progression was 0.28 vs an average TFS of 2.1 and an average fibrosis progression rate of 0.22 for those without collaterals (P = .00001 and P = .01, respectively). Of the 101 with collaterals, oxygen saturation was 91% ± 4% vs 93% ± 3% (P = .048) without collaterals. Of the 164, 86 (52%) underwent ultrasound shear-wave elastography. Of the 86 patients undergoing elastography, 50 (58%) were performed in those with collaterals, and 36 (42%) in those without collaterals. For the 50 with collaterals, average elastography values were 13.3 vs 11.2 kPa for the 36 without collaterals (P = .006). We found no statistically significant differences for age at biopsy, Fontan duration, Fontan-type, type of functional univentricle, laboratory, clinical, or hemodynamic values between those with or without collaterals. CONCLUSIONS: The presence of angiographically demonstrated venovenous collaterals was associated with statistically, significantly more advanced liver fibrosis than those without collaterals.

ABSTRACT

BACKGROUND: We reviewed data on patients born with critical congenital heart disease in the state of Nevada and analyzed detection via prenatal diagnosis versus newborn pulse oximetry screening, location of birth, and gestational age at birth. METHODS: We inquired our databases and electronic health records for all patients with critical congenital heart disease born in Nevada between January 2016 and May 2019. RESULTS: We identified 218 live born patients. Of the 218, average gestational age was 38 weeks (±2.2 weeks). Of the 218, 171 (78%) were prenatally diagnosed, 37 (17%) were diagnosed by immediate postnatal signs and symptoms, 8 (4%) had false-negative pulse oximetry screens that resulted in post-hospital discharge presentations, and 2 (1%) had positive pulse oximetry screens. The eight post-hospital discharge presentations included four in extremis, two with extreme cyanosis, and two dying at home. Of the 171 prenatally diagnosed patients, 157 (92%) were born at the Nevada hospital with the congenital cardiac unit. CONCLUSION: To the best of our knowledge, our results represent the highest statewide, general population prenatal detection of critical congenital heart disease in the United States. Our high prenatal detection rate led to the majority of patients being born at the Nevada facility with the congenital heart unit, limiting intrastate neonatal transports. On average, patients were born at term. Further, in Nevada, state-mandated, universal pulse oximetry screening resulted in more false-negative results than positive results.

ABSTRACT

Aluminium phosphide (AP) is a pesticide used against rodents and insects. Exposure of AP to water releases phosphine gas. Phosphine is a highly toxic mitochondrial poison to which there is no known antidote. We report a case of a 3-year-old female with accidental home exposure to AP, which resulted in cardiac arrest, who was successfully supported with extracorporeal membrane oxygenation (ECMO).

ABSTRACT

OBJECTIVE: Aortic cross-clamp and cardiopulmonary bypass times are independent predictors of postoperative morbidity and mortality. Reducing ischemic times with automated titanium fasteners may improve surgical outcomes. This study compared operative times and costs of titanium fasteners versus hand-tied knots for prosthesis securement in open aortic valve replacement. METHODS: A randomized control trial was conducted during a 16-month period at a single university medical center. Patients undergoing elective aortic valve replacement were randomized to the titanium fastener (n = 37) or hand-tied groups (n = 36). Knotting, aortic cross-clamp, cardiopulmonary bypass, and total operating room times were recorded. Hospital charges were also calculated for these procedures. RESULTS: Baseline characteristics, concomitant procedures, prosthetic valve size, and sutures were similar between groups. The titanium fastener group had significantly reduced knotting (7.4 vs. 13.0 minutes, P < 0.001), aortic cross-clamp (69 vs. 90 minutes, P < 0.05), cardiopulmonary bypass (86 vs. 114 minutes, P < 0.05), and total operating room times (234 vs. 266 minutes, P < 0.05). Intraoperative complications occurred more frequently in the hand-tied group compared with the titanium fastener group. Postoperative complications were similar between groups. Operating room costs were significantly higher in the titanium fastener group (US $10,428 vs. US $9671, P = 0.01). Hospitalization costs did not differ significantly between the titanium fastener and hand-tied group (US $23,987 vs. US $21,068, P = 0.12). CONCLUSIONS: Titanium fastener use was associated with shorter knotting, aortic cross-clamp, cardiopulmonary bypass, and operating room times and fewer intraoperative complications in open aortic valve replacement, without significantly increasing hospitalization cost.

ABSTRACT

The development of technology and limitation of numerous ventricular assist devices has increased usage of the total artificial heart (TAH) for mechanical circulatory support. A primary important feature of TAH is that it is one of the few mechanical circulatory support devices that provides biventricular support. As the number of patients with TAH rises, spreading awareness about the device in the interventional radiology community is important.

ABSTRACT

OBJECTIVES: There are various strategies in the use of temporary mechanical circulatory support following orthotopic heart transplant (OHT). We sought to examine the outcomes following different temporary mechanical circulatory support strategies for acute graft failure. METHODS: Patients who received an OHT between 2001 and 2015 at a single institution were retrospectively reviewed. Patients were divided into 2 groups based on the need for temporary mechanical circulatory support (TMCS). RESULTS: A total of 9.9% (19 of 192) of patients required TMCS following OHT. There were no significant differences in the preoperative demographics between groups. Six patients (32%) required a biventricular assist device, 9 patients (47%) required a right ventricular assist device and 4 patients (21%) required a veno-arterial extracorporeal membrane oxygenator. Perioperative morbidity was comparable between all groups. Our entire TMCS cohort had 94.7% 30-day and 61.1% 1-year survival. When compared with the OHT patients with no TMCS (97.1% at 30 days and 92.8% at 1 year), survival was inferior in TMCS patients ( P = 0.01 at 30 days, P < 0.001 at 1 year, P < 0.001 overall). CONCLUSIONS: Acute graft failure requiring TMCS has inferior overall survival. Larger, multi-institutional studies are needed to further elucidate these differences and identify the best TMCS mode.

ABSTRACT

BACKGROUND: The optimal choice for pulmonary valve replacement (PVR) remains controversial. This study hypothesized that xenografts used for PVR would result in prolonged long-term survival and freedom from reoperation. METHODS: Children and adults with congenital heart disease requiring PVR using a xenograft from 1980 to 1985 were reviewed. In all cases, the xenograft valve was either sewn or manufactured into a Dacron conduit, and the conduit was sewn to the pulmonary artery bifurcation. Clinical data were analyzed, and survival and freedom from reoperation were determined using Kaplan-Meier analysis. RESULTS: Twenty-four patients received a xenograft for PVR at 14.6 ± 5.6 years. Conduit size ranged from 21 to 27 mm. Most patients received a Carpentier-Edwards valved conduit (n = 17), followed by a Hancock valved conduit (n = 5) and an Ionescu-Shiley valve sewn into a Dacron graft (n = 2). No perioperative deaths occurred. Reoperation was required mainly for pulmonary stenosis (72.7%), followed by pulmonary insufficiency (18.2%), or both stenosis and insufficiency (9%). Freedom from reoperation was 90%, 56%, 43%, and 14% at 10, 20, 25, and 30 years, respectively. At most recent follow-up the was only death, which was related to severe biventricular failure 25 years after conduit implant. CONCLUSIONS: PVR using a xenograft valved conduit results in prolonged freedom from reoperation and excellent long-term survival. These data, which provide long-term follow-up information on xenograft valves after PVR.
