BACKGROUND: Various surgical strategies designed to relieve left ventricular outflow tract obstruction (LVOTO) and correct mitral regurgitation (MR) in hypertrophic obstructive cardiomyopathy (HOCM) have evolved, yet reports on the long-term outcomes of each technique are scarce. We provide an update on over 20 years' experience at our institution in the standardized surgical treatment of HOCM. METHODS: Between April 1986 and April 2014, 320 cases of endomyocardial resection and 305 septal myectomies were performed at our institution...

Syndromic diarrhea/tricho-hepato-enteric syndrome (SD/THE) is a rare disease linked to the loss of function of either TTC37 or SKIV2L, two components of the SKI complex. It is characterized by a combination of 9 signs (intractable diarrhea, hair abnormalities, facial dysmorphism, immune abnormalities, IUGR/SGA, liver abnormalities, skin abnormalities, congenital heart defect and platelet abnormalities). We present a comprehensive review of the management of SD/THE and tested therapeutic regimens. A review of the literature was conducted in May 2017: 29 articles and 2 abstracts were included describing a total of 80 patients, of which 40 presented with mutations of TTC37, 14 of SKIV2L...

Heart transplantation has been shown to prolong survival significantly for people who have advanced heart disease. Even with improved prognosis, heart transplant recipients experience a lower overall quality of life compared to their healthy counterparts, which is correlated with high rates of depression and other psychiatric disorders. Our case report examines factors affecting the quality of life over a long period of time in a patient who received a heart transplant 22 years ago. This case is unusual because the patient overcame depression with just a minimal dosage of antidepressants due to her unwavering hope, resilience, and strong social support...

A 54-year-old man with polycystic liver disease received a domino liver transplantation (DLT) from a patient of hereditary ATTR amyloidosis with the transthyretin Ser50Arg mutation. Ten years after transplantation, he felt a slight numbness in his toes, and cardiac amyloidosis was simultaneously suspected upon a heart function evaluation. Biopsy specimens from the myocardium revealed transthyretin amyloidosis with the Ser50Arg mutation. Oral tafamidis therapy has inhibited the progression of neurological and cardiovascular symptoms this far...

BACKGROUND/PURPOSE: We investigated whether (99m)Tc-DTPA galactosyl human serum albumin (GSA) liver scintigraphy could help evaluate post-Kasai procedure hepatic functional reserve in order to inform therapeutic strategies, including liver transplantation. METHODS: GSA scintigraphy was performed post-Kasai procedure. Patients were classified as having favorable (native liver survival) or poor (liver transplantation or death) prognoses. The clearance index (HH15), receptor index (LHL15), and time at which cumulative liver radioactivity reached 85% of heart plus liver activity (T0...

Cardiovascular disease is the leading cause of death in patients with end-stage renal disease (ESRD) and often goes undetected. Abnormal coronary flow reserve (CFR), which predicts increased risk of cardiac death, may be present in patients with ESRD without other evidence of coronary artery disease (CAD). We prospectively studied 131 patients who had rest and dipyridamole pharmacologic stress N(13)-ammonia positron emission tomography myocardial perfusion imaging (PET MPI) for kidney transplant evaluation...

BACKGROUND: In Japan, ventricular assist devices (VADs) have been used for patients with severe heart failure as a bridge to transplantation (BTT) since 1992. However, it was not until 1997, when the Organ Transplant Law was enacted, that medical devices received approval by the national health insurance system for that use. To encourage research and development of innovative medical devices, the Pharmaceuticals and Medical Devices Agency has established a public-private partnership in collaboration with academic societies, hospitals and manufacturers...

BACKGROUND: The clinical course of idiopathic pulmonary fibrosis (IPF) is unpredictable. Clinical prediction tools are not accurate enough to predict disease outcomes. METHODS: We enrolled patients with IPF diagnosis in a six-cohort study at Yale University (New Haven, CT, USA), Imperial College London (London, UK), University of Chicago (Chicago, IL, USA), University of Pittsburgh (Pittsburgh, PA, USA), University of Freiburg (Freiburg im Breisgau, Germany), and Brigham and Women's Hospital-Harvard Medical School (Boston, MA, USA)...

BACKGROUND: Limits on the frequency of whole blood donation exist primarily to safeguard donor health. However, there is substantial variation across blood services in the maximum frequency of donations allowed. We compared standard practice in the UK with shorter inter-donation intervals used in other countries. METHODS: In this parallel group, pragmatic, randomised trial, we recruited whole blood donors aged 18 years or older from 25 centres across England, UK...

A 63-year-old man presented with a 1-year history of atrial tachycardia (AT) 6 years after orthotopic heart transplantation with bicaval anastomosis. Twelve-lead electrocardiogram showed monomorphic AT with isoelectric intervals across all leads and strikingly irregular PP intervals. At electrophysiology study, the native left atrium's rhythm was atrial fibrillation (AF) while the donor atria exhibited centrifugal activation of irregular cycle length originating from a site along the left atrial anastomosis...

BACKGROUND: Continuous flow (CF) left ventricular assist devices (LVADs) improve survival in end-stage heart failure patients who are ineligible for cardiac transplantation. Their use in this population (referred to as destination therapy) is increasing in many countries, yet they are not routinely funded for this indication in Canada. We assessed the cost-effectiveness of destination therapy CF-LVADs from the perspective of the Canadian health care payer. METHODS: A Markov model was used to project the outcomes and costs of 2 treatment pathways, CF-LVAD implantation and medical management alone, in an end-stage heart failure patient cohort ineligible for transplantation...

Management of adults with failing Fontan physiology poses many challenges, especially as transplantation offers the only realistic alternative to palliative care. We present the first combined heart and liver transplant performed in Europe, for a late survivor of single ventricle palliation with the Fontan circulation. In addition to the conventional medical and surgical challenges posed, we highlight the management of the associated multi-organ failure with focus on the liver and novel strategies for assessment and optimization...

We aimed to describe worldwide DCD HT experience in children using the International Society for Heart and Lung Transplantation Registry. The Registry was queried for primary HT performed in children (2005-2014). Kaplan-Meier analysis was used to assess survival for recipients grouped by DCD or DBD hearts. Recipient characteristics were compared between DCD and DBD and between survivors and non-survivors of DCD HT. Among 3877 pediatric HT performed, 21 (0.5%) were DCD. DCD 1-year survival was 61% vs 91% DBD, P < ...

BACKGROUND: Right ventricular (RV)-scar related ventricular tachycardia (VT) is often due to arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) or cardiac sarcoidosis (CS), but some patients whose clinical course has not been described do not fulfill diagnostic criteria for these diseases. We sought to characterize the electrophysiologic substrate and catheter ablation outcomes of such patients, termed RV cardiomyopathy of unknown source (RCUS). METHODS AND RESULTS: Data of 100 consecutive patients who presented with RV cardiomyopathy and/or RV-related VT for ablation was reviewed (51 ARVC/D, 22 CS; 27 RCUS)...

BACKGROUND: Heart transplantation (HTX) is an established therapy for end-stage heart disease. The aim of this study was to determine whether application of oral bisphosphonates is effective in preventing osseous complications after HTX. METHODS: Thirty-three cardiac transplant recipients were treated with alendronate 70 mg/week or risedronate 35 mg/week in combination with 1000 mg calcium and 800 IU vitamin D. Markers of bone metabolism and dual energy X-ray absorptiometry (DXA) were determined directly after HTX and 2 years later...

BACKGROUND: The development of donor-specific antibodies (DSA) to human leukocyte antigens (HLA) has been associated with acute rejection and allograft failure after heart transplantation. Not all DSA, however, can fix complement. METHODS: To determine the association between complement-fixing DSA and heart transplant outcomes, we retrospectively analyzed results obtained using the C1q solid-phase assay that specifically detects complement-fixing DSA in parallel with the standard IgG assay in 121 adult heart transplant recipients...

BACKGROUND/OBJECTIVES: Frailty, characterized by low physiological reserves, is strongly associated with vulnerability to adverse outcomes. Features of frailty overlap with those of advanced heart failure, making a distinction between them difficult. We sought to determine whether implantation of a left ventricular assist device (LVAD) would decrease frailty. DESIGN: Prospective, cohort study. SETTING: Five academic medical centers. PARTICIPANTS: Frail individuals (N = 29; mean age 70...

PURPOSE OF REVIEW: Heart failure is increasing in prevalence with a lack of recently developed therapies that produce major beneficial effects on its associated mortality. MicroRNAs are small non-coding RNA molecules that regulate gene expression, are differentially regulated in heart failure, and are found in the circulation serving as a biomarker of heart failure. RECENT FINDINGS: Data suggests that microRNAs may be used to detect allograft rejection in cardiac transplantation and may predict the degree of myocardial recovery in patients with a left ventricular assist device or treated with beta-blocker therapy...
