• Comparison of combined heart‒liver vs heart-only transplantation in pediatric and young adult Fontan recipients. The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation Sganga, D., Hollander, S. A., Vaikunth, S., Haeffele, C., Bensen, R., Navaratnam, M., McDonald, N., Profita, E., Maeda, K., Concepcion, W., Bernstein, D., Chen, S. 2020

  Abstract

  BACKGROUND: Indications for a heart‒liver transplantation (HLT) for Fontan recipients are not well defined. We compared listing characteristics, post-operative complications, and post-transplant outcomes of Fontan recipients who underwent HLT with those of patients who underwent heart-only transplantation (HT). We hypothesized that patients who underwent HLT have increased post-operative complications but superior survival outcomes compared with patients who underwent HT.METHODS: We performed a retrospective review of Fontan recipients who underwent HLT or HT at a single institution. Characteristics at the time of listing, including the extent of liver disease determined by laboratory, imaging, and biopsy data, were compared. Post-operative complications were assessed, and the Kaplan‒Meier survival method was used to compare post-transplant survival. Univariate regression analyses were performed to identify the risk factors for increased mortality and morbidity among patients who underwent HT.RESULTS: A total of 47 patients (9 for HLT, 38 for HT) were included. Patients who underwent HLT were older, were more likely to be on dual inotrope therapy, and had evidence of worse liver disease. Whereas ischemic time was longer for the group who underwent HLT, post-operative complications were similar. Over a median post-transplant follow-up of 17 (interquartile range: 5-52) months, overall mortality for the cohort was 17%; only 1 patient who underwent HLT died (11%) vs 7 patients who underwent HT (18%) (p = 0.64). Among patients who underwent HT, cirrhosis on pre-transplant imaging was associated with worse outcomes.CONCLUSIONS: Despite greater inotrope need and more severe liver disease at the time of listing, Fontan recipients undergoing HLT have post-transplant outcomes comparable with those of patients undergoing HT. HLT may offer a survival benefit for Fontan recipients with liver disease.

• Does liver biopsy accurately measure fibrosis in Fontan associated liver disease? A comparison of liver biopsy pre-combined heart and liver transplant and liver explant post-transplant. Clinical transplantation Vaikunth, S. S., Higgins, J. P., Concepcion, W., Haeffele, C., Wright, G. E., Chen, S., Lui, G. K., Daugherty, T. 2020: e14120

  Abstract

  The accuracy of liver biopsy to stage fibrosis due to Fontan associated liver disease (FALD) remains unclear. We compared results of biopsy pre-combined heart and liver transplantation (CHLT) to results of whole liver explant. Liver biopsy and explants from 15 Fontan patients (ages 16 - 49, median 28 years) were retrospectively reviewed. Staging was as follows: stage 0: no fibrosis, stage 1: pericellular fibrosis, stage 2: bridging fibrosis, stage 3: regenerative nodules. There is no stage 4. Clinical characteristics including Model of End-stage Liver Disease eXcluding INR and Varices, Ascites, Splenomegaly, and Thrombocytopenia (VAST) scores were collected, and descriptive statistics and Mann-Whitney U tests used to analyze data. All patients had biopsies with at least bridging fibrosis, and all had nodularity on explant; transjugular biopsy never overestimated fibrosis. Explant showed higher grade fibrosis (Stage 3) than pre-CHLT biopsy (Stage 2) in 6 of 15 patients and equal grade of fibrosis (Stage 3) in 9 of 15 patients. Though clinical characteristics varied significantly, VAST score was ≥ 2 in all but two patients. Transjugular liver biopsy does not overestimate and can underestimate fibrosis in Fontan patients undergoing CHLT, likely due to the patchy nature of fibrosis in FALD.

• Heart failure in the adult Ebstein patient. Heart failure reviews Schultz, K. n., Haeffele, C. L. 2020

  Abstract

  Ebstein anomaly comprises approximately 1% of all congenital heart diseases. It occurs when the tricuspid valve fails to properly delaminate from the right ventricle, resulting in a clinical spectrum of abnormal tricuspid valve morphology and right ventricular dysfunction. Due to the anatomy of the tricuspid valve and right ventricle, as well as associated right- and left-sided pathology, patients are at risk for both right and left ventricular failure and the associated symptoms of each. Ebstein patients are also at risk for atrial arrhythmias, due to the atrial enlargement intrinsic to the anatomy, as well as the presence of potential accessory pathways. Arrhythmias are generally poorly tolerated, particularly in the setting of ventricular dysfunction. Cyanosis may also be present in Ebstein patients, due to the common occurrence of atrial communications, which can exacerbate other symptoms of heart failure. Treatment of heart failure can be through pharmacologic and procedural interventions, depending on the underlying cause of heart failure. While early heart failure symptoms may be treated with medical management, most Ebstein patients will require surgery. Various surgical and catheter-based interventions targeting the tricuspid valve and the atrialized right ventricular tissue have been developed to help treat the underlying cause of the heart failure. The optimal timing of transcatheter and surgical intervention in the Ebstein patient to prevent or treat heart failure needs further study.

• Percutaneous Pulmonary Vein Stenting to Treat Severe Pulmonary Vein Stenosis After Surgical Reconstruction. Innovations (Philadelphia, Pa.) Dalal, A. R., Markham, R. n., Haeffele, C. n., Sharma, R. n., Watkins, A. C. 2020: 1556984520933962

  Abstract

  A 36-year-old female underwent left lower lobectomy with left atrial and left upper pulmonary vein (LUPV) reconstruction with a bovine pericardial patch for an intrathoracic pheochromocytoma. Postoperatively, she developed shortness of breath and transesophageal echocardiography demonstrated LUPV stenosis with increased velocities. Computed tomography angiogram of the chest revealed LUPV stenosis at the left atrium ostium with an area of 39 mm2. Under angiographic and echocardiographic guidance, a 10 × 19 mm Omnilink Elite uncovered stent was deployed in the LUPV ostia. While reported following left atrial ablation, pulmonary vein stenting can be successful in a pulmonary vein surgically reconstructed with bovine pericardium.

• Risk Estimates for Atherosclerotic Cardiovascular Disease in Adults With Congenital Heart Disease AMERICAN JOURNAL OF CARDIOLOGY Lui, G. K., Rogers, I. S., Ding, V. Y., Hedlin, H. K., MacMillen, K., Maron, D. J., Sillman, C., Romfh, A., Dade, T. C., Haeffele, C., Grady, S. R., McElhinney, D. B., Murphy, D. J., Fernandes, S. M. 2017; 119 (1): 112-118

  Abstract

  The adult with congenital heart disease (CHD) is at risk of developing atherosclerotic cardiovascular disease (ASCVD). We performed a cross-sectional study to describe established ASCVD risk factors and estimate 10-year and lifetime risk of ASCVD in adults over age 18 with CHD of moderate or great complexity using 3 validated risk assessment tools-the Framingham Study Cardiovascular Disease Risk Assessment, the Reynolds Risk Score, and the ASCVD Risk Estimator. We obtained extensive clinical and survey data on 178 enrolled patients, with average age 37.1 ± 12.6 years, 51% men. At least 1 modifiable ASCVD risk factor was present in 70%; the 2 most common were overweight/obesity (53%) and systemic hypertension (24%). Laboratory data were available in 103 of the 178 patients. Abnormal levels of glycated hemoglobin, high-sensitivity C-reactive protein, and high-density lipoprotein were each found in around 30% of patients. The 10-year ASCVD predicted risk using all 3 tools was relatively low (i.e., at least 90% of patients <10% risk), yet the median estimated lifetime risk was 36%. In conclusion, ASCVD risk factors are prevalent in adults with CHD. The risk estimation tools suggest that this population is particularly vulnerable to ASCVD with aging and should undergo guideline-based screening and management of modifiable risk factors.

• Dextro-Transposition of the Great Arteries Long-term Sequelae of Atrial and Arterial Switch CARDIOLOGY CLINICS Haeffele, C., Lui, G. K. 2015; 33 (4): 543-?

  Abstract

  Over the last 50 years, improved surgical techniques and progressive medical management have allowed patients with complete or dextro-transposition of the great arteries (D-TGA) to survive into adulthood. Older adult patients underwent an atrial switch procedure (Mustard or Senning operation), whereas the younger cohort of patients with TGA has undergone the arterial switch operation (ASO). The Mustard/Senning maintains the right ventricle as the systemic ventricle, whereas the more recently adopted ASO attempts to restore normal physiologic and anatomic relationships. Neither operation is without consequence. Neither is without consequence and require long term follow up.

• Receptor-selective coactivators as tools to define the biology of specific receptor-coactivator pairs MOLECULAR CELL Gaillard, S., Grasfeder, L. L., Haeffele, C. L., Lobenhofer, E. K., Chu, T., Wolfinger, R., Kazmin, D., Koves, T. R., Muoio, D. M., Chang, C., McDonnell, D. P. 2006; 24 (5): 797-803

  Abstract

  In the absence of specific high-affinity agonists and antagonists, it has been difficult to define the target genes and biological responses attributable to many of the orphan nuclear receptors (ONRs). Indeed, it appears that many members of this receptor superfamily are not regulated by classical small molecules but rather their activity is controlled by interacting cofactors. Motivated by this finding, we have developed an approach to genetically isolate specific receptor-cofactor pairs in cells, allowing us to define the biological responses attributable to each complex. This is accomplished by using combinatorial peptide phage display to engineer the receptor interacting domain of each cofactor such that it interacts selectively with one nuclear receptor. In this study, we describe the customization of PGC-1alpha and its use to study the biology of the estrogen-related receptor alpha (ERRalpha) in cultured liver cells.
