PURPOSE: Ultra-high resolution single-photon emission computed tomography (SPECT) system, using multiple pinhole collimators, has been applied to the imaging of small rodents. We aimed to compare the myocardial infarction (MI) area on quantitative perfusion single-photon emission computed tomography (QPS; Cedars-Sinai Medical Center, USA) with that on high-resolution autoradiography in rat model to determine the accuracy of perfusion defect measurement by QPS. PROCEDURES: After thoracotomy, rats (n = 9) had their left coronary arteries occluded and reperfused before injection with 185 MBq [99mTc] methoxyisobutylisonitrile ([99mTc]MIBI) for SPECT and autoradiography...

OBJECTIVE: Speckle tracking echocardiography (STE) enables global and regional evaluation of the left ventricle (LV); therefore, it is the most useful method for detecting subclinical dysfunction in patients exposed to cardiotoxic agents. A novel technique triplane (3P) echocardiography also allows single beat assessment of LV global longitudinal strain values. We firstly aimed to demonstrate both two-dimensional (2D)- and 3PSTE-derived LV global longitudinal strain measurements in children after anthracycline exposure...

BACKGROUND: Pulmonary artery wedge pressure (PAWP) has been shown to correlate better with left atrial pressure (LAP) than ventricular end-diastolic pressure (VEDP) in acquired heart disease. The correlation between VEDP and PAWP and their performance as surrogates for LAP in Fontan patients is unknown. METHODS: Offline single-beat simultaneous measurement of PAWP and VEDP was performed in 50 adult Fontan patients and non-simultaneous hemodynamic data abstracted for calculation of pulmonary vascular resistance (PVR)...

The increasing survival in the adulthood of patients with congenital heart disease (CHD) has changed the epidemiology of adult CHD (ACHD) patients and has led to an increment in hospitalization rates due to heart failure (HF). ACHD patients hospitalized for HF have a five-fold higher risk of death HF than those compensated. HF occurs predominantly in patients with tetralogy of Fallot, single ventricles, and after the Mustard operation for transposition of the great arteries. Diagnostic strategies applied in acquired HF patients are usually used to evaluate ACHD patients, but sometimes this can postpone the identification of HF that can become manifest with unusual and peculiar signs or symptoms...

Catheter-based interventions in the early post-operative period are performed with caution due to concerns for increased procedural risk, particularly across fresh suture lines. The recently published CRISP scoring system provides prospective risk stratification based on pre-procedural criterion. In an effort to refine the assessment of risk in patients undergoing post-operative catheter-based interventions, the predicted risk of an adverse event based on CRISP scores was compared to actual adverse event rates...

A patient with a history of lung adenocarcinoma was admitted because of palpitation. Transthoracic echocardiogram revealed a mass (74×42 mm) in the right ventricle. Computed tomography showed a tumor lesion in the right ventricular cavity but no other distant metastasis. Coronary angiography revealed well-developed small branches to the tumor. After right heart catheterization, a pathological analysis of a tumor biopsy demonstrated adenocarcinoma. We diagnosed the patient with right ventricular metastasis of lung cancer...

Children with single-ventricle disease experience high mortality and complex care. In other life-limiting childhood illnesses, paediatric palliative care may mitigate maternal stress. We hypothesised that early palliative care in the single-ventricle population may have the same benefit for mothers. In this pilot randomised trial of early palliative care, mothers of infants with prenatal single-ventricle diagnoses completed surveys measuring depression, anxiety, coping, and quality of life at a prenatal visit and neonatal discharge...

INTRODUCTION: Ablation in the left ventricle (LV) is associated with a risk of thromboembolism. There are limited data on the use of specific thromboembolic prophylaxis strategies post-ablation. We aimed to evaluate a thromboembolic prophylaxis protocol after ventricular tachycardia (VT) ablation. METHODS AND RESULTS: The index procedures of 217 patients undergoing ablation for infarct-related VT with open irrigated-tip catheters were included. Patients with large LV endocardial ablation area (> 3 cm between ablation lesions) were started on low-dose, slowly escalating unfractionated heparin (UFH) infusion 8 hours after access hemostasis, followed by 3 months of anticoagulation...

BACKGROUND: Single ventricle heart disease (SVHD) adolescents show cognitive impairments and anxiety and depressive symptoms, indicating the possibility of brain injury in regions that control these functions. However, brain tissue integrity in cognition, anxiety, and depression regulatory sites in SVHD remains unclear. We examined brain tissue changes in SVHD compared to controls using T2-relaxometry procedures, which measure free water content and show tissue injury. METHODS: Proton-density and T2-weighted images, using a 3...

BACKGROUND: Mechanical circulatory support (MCS) of a failing Fontan circulation remains challenging. We hypothesized that MCS can be provided by converting the Fontan circulation into a mechanically assisted single ventricle parallel circulation (MASVC). METHODS: A porcine model of functionally univentricular circulation was created under cardiopulmonary bypass (CPB) by performing an atrial septectomy, tricuspid valvectomy, and interrupting antegrade pulmonary blood flow...

In cardiac physiology, single ventricle typically refers to the presence of a dominant systemic ventricle along with a hypoplastic ventricle. The Fontan operation is used to repair the single ventricle by directing deoxygenated systemic venous flow to the pulmonary arterial circulation. Normal pregnancy physiology, particularly increased intravascular volume, increased heart rate, increased cardiac output, hypercoagulability and decreased systemic vascular resistance, can exacerbate cardiac disease in patients with Fontan circulation, leading to pregnancy complications...

Turner syndrome (TS) patients with hypoplastic left heart syndrome (HLHS) have poor single ventricle palliation outcomes; therefore, consideration of other potential management strategies is important. Little is known about heart transplantation (HTx) in this group, as standard HTx databases do not allow for identification of TS. This study describes experiences and outcomes of HTx in TS using a unique linkage between the Scientific Registry of Transplant Recipients and the Pediatric Health Information System databases...

Regulatory factor X4 (RFX4) isoform 1 is a recently discovered isoform of the winged helix transcription factor RFX4, which can bind to X-box consensus sequences that are enriched in the promoters of cilia-related genes. Early insertional mutagenesis studies in mice first identified this isoform, and demonstrated that it was crucial for mouse brain development. RFX4 isoform 1 is the only RFX4 isoform significantly expressed in the mouse fetal and adult brain. In this study, we evaluated conditional knock-out (KO) mice in which one or two floxed alleles of Rfx4 were deleted early in development through the use of a Sox2-Cre transgene...

OBJECTIVES: Diastolic strain and strain rate, combined with E (peak transmitral velocity), have been proposed as novel noninvasive predictors of left ventricle (LV) filling pressures, avoiding angulation errors inherent to tissue Doppler indices (TDI). The primary objective was to study the correlation of strain-based indices (SBI) and TDI with pulmonary artery catheter-derived LV end-diastolic pressures (LVEDP). The secondary aim was to determine appropriate cut-off of indices to predict LVEDP ≥15 mmHg...

Isolated coarctation of the aorta (CoA) is estimated by the Centers for Disease Control and Prevention to account for 4%-6% of all congenital heart disease (CHD) in the United States, with a reported prevalence of ~4 per 10 000 live births. Prenatal recognition of coarctation is important as it may improve neonatal survival and reduce morbidity. However, despite advances in imaging and the trend toward detailed aortic arch assessment as part of a comprehensive fetal echocardiogram, isolated CoA may still elude prenatal detection, with potentially lethal consequences if the diagnosis is not suspected and the patent ductus arteriosus (PDA) closes spontaneously in postnatal life...

Fetal cardiac intervention (FCI) offers the potential to alter in utero anatomy and physiology. For aortic stenosis with evolving hypoplastic left heart syndrome and pulmonary atresia with intact ventricular septum with evolving hypoplastic right heart syndrome, FCI may result in maintenance of a biventricular circulation, thus avoiding single-ventricle palliation and its attendant complications. In the case of hypoplastic left heart syndrome with intact atrial septum, FCI may ameliorate in utero pathophysiology and portend a more favorable postnatal prognosis...
