A simplified state-space model of biventricular assist device (BiVAD)-cardiovascular system (CVS) interaction is presented. The state-space equations includes a six-compartments CVS model incorporating the ventricles, the pulmonary and systemic circulations as well as the non-linear behavior of the valve flow, together with a left ventricular assist device (LVAD) and a right ventricular assist device (RVAD) component. The left and right pump speeds serve as the input variables for the state-space model. The model is simulated with three operational modes, i...

Heart failure with preserved ejection fraction (HFPEF) is considered as a major public health problem. Traditionally, HFPEF is diagnosed based on a "normal" EF, but the studies have explored the potential role of left ventricular mechanics. Furthermore, right ventricular mechanics and bi-ventricular interaction in HFPEF is currently not well understood. In this study, we aim to develop a framework using a hyperelastic warping approach to quantify bi-ventricular and septum strains from cardiac magnetic resonance (CMR) images...

Congenital heart disease is the most common birth defect, with an incidence of 75 in every 1000 births. As a result of improved interventions, 90% of people with congenital heart disease now survive to adulthood. They must undergo regular imaging to assess their biventricular (left and right ventricular) function. Analysis of the images is problematic due to the large variety of shapes and complex geometry. In this paper we extend a biventricular modeling method to improve the analysis of MR images from congenital heart disease patients...

INTRODUCTION: To develop and test a lumped parameter model to simulate and compare the effects of the simultaneous use of continuous flow (CF) and pulsatile flow (PF) ventricular assist devices (VADs) to assist biventricular circulation vs. single ventricle circulation in pediatrics. METHODS: Baseline data of 5 patients with biventricular circulation eligible for LVAD and of 5 patients with Fontan physiology were retrospectively collected and used to simulate patient baselines...

Prenatal intervention of severe fetal aortic valve stenosis by ultrasound-guided percutaneous balloon valvuloplasty has been performed to prevent the progression to hypoplastic left heart syndrome, and achieve biventricular circulation in neonates. Here we report a case of fetal aortic valvuloplasty prenatally diagnosed with aortic stenosis at 24 weeks of gestation and showed worsening features on a follow-up echocardiography. Prenatal aortic valvuloplasty was performed at 29 weeks of gestation, and was a technical success...

Pulmonary hypertension significantly changes biventricular anatomy and physiology, frequently evolving to clinical deterioration and right ventricular failure. The case of a woman developing atrial arrhythmias complicating dipyridamole stress in concomitance with scintigraphic "D-shaped" left ventricle is briefly reported. Although rare, our finding may suggest that nonselective vasodilators should be used with caution in this clinical setting.

Dilated cardiomyopathy (DCM) is characterized by dilation and impaired contraction of the left ventricle or both ventricles. Among hereditary DCM, the genetic causes are heterogeneous, and include mutations encoding cytoskeletal, nucleoskeletal, mitochondrial, and calcium-handling proteins. We report three severely affected males, in a four-generation pedigree, with DCM phenotype who underwent cardiac transplant. Cardiomegaly with marked biventricular dilation and fibrosis were noticeable histopathological findings...

A restrictive transfusion strategy led us to routinely try to conduct donor-blood free open-heart surgery even in neonates. The cardio-pulmonary bypass (CPB) circuit was minimized by priming volumina at 73 ml for the smallest patients with body weight up to 2.5 kg and 85-95 ml for those with body weight of more than 2.5 kg, and by positioning the console as close as possible to operation table. Measures were applied to save blood during the procedure. Transfusion threshold of 8 g/dl hemoglobin was retained...

Ventricular Assist Device (VAD) therapy is increasingly utilized to support patients in end-stage heart failure. However, VAD programs are resource intensive and demand active monitoring in order to ensure long term sustainability. The purpose of this study was to analyze total cost trends of the VAD program at our academic medical center.Retrospective analysis of UCLA's VAD program between years 2013-2014 was performed. Total in-hospital costs from the date of VAD surgery admission were queried and normalized to a Z-score...

BACKGROUND: The effective non-invasive identification of coronary artery disease (CAD) and its proper referral for invasive treatment are still unresolved issues. We evaluated our quantification of myocardium at risk (MAR) from our second generation 3D MPI/CTA fusion framework for the detection and localization of obstructive coronary disease. METHODS: Studies from 48 patients who had rest/stress MPI, CTA, and ICA were analyzed from 3 different institutions. From the CTA, a 3D biventricular surface of the myocardium with superimposed coronaries was extracted and fused to the perfusion distribution...

INTRODUCTION: The subcutaneous implantable cardioverter defibrillator (ICD) has emerged as a viable therapeutic option for patients who are deemed high risk for sudden cardiac death. Previous studies have shown that 7-15% of patients are not candidates for the S-ICD based on their intrinsic QRS/T-wave morphology. Presently, it is not known if the S-ICD can be considered as supplementary therapy in patients who are ventricularly paced. We sought to determine the proportion of ventricularly paced patients who would qualify for an S-ICD...

Cardiovascular complications induced by adjuvant cancer therapies may become symptomatic after many years, being responsible for increased morbidity and mortality in long-term survivors. We report a case of a 54-year old female admitted for severe heart failure induced by myocardial and valvular damage after postoperative adjuvant therapy for left breast cancer 6 years ago. Her recent history revealed nonST elevation myocardial infarction in the absence of significant cardiovascular risk factors. Transthoracic echocardiography, tissue Doppler imaging and speckle-tracking imaging revealed severe biventricular systolic dysfunction, severe mitral and tricuspid regurgitation and severe pulmonary hypertension...

Left atrial (LA) calcification is mostly observed in patients with rheumatic mitral valve (MV) diseases who underwent surgical treatment. We report a case of LA calcification in a 69-year-old woman presented with dyspnea and cyanosis. Admission electrocardiogram showed atrial fibrillation and biventricular hypertrophy. Her chest roentgenogram revealed cardiomegaly and a curvilinear whitish shadow in the area of LA. Transthoracic echocardiography revealed severe mitral stenosis and massive LA thrombosis. The patient underwent an emergent surgery, during which the whitish line on chest roentgenogram proved to be a calcified LA inner wall...

BACKGROUND: Children with body weight less than 2.5 kg who undergo the arterial switch operation (ASO) represent a challenging group. We sought to determine outcomes of patients with weight less than 2.5 kg at ASO at a single institution. METHODS: All patients who underwent an ASO with biventricular repair and weighed less than 2.5 kg at time of surgery were identified from the hospital database and reviewed retrospectively. RESULTS: From 1983 to 2014, 870 patients underwent an ASO with biventricular repair at our institution...

OBJECTIVE: Impaired ventricular performance in patients who underwent surgery for congenital heart defect (CHD) may ultimately result in clinical heart failure. It is therefore important to regularly evaluate the left ventricular (LV) and right ventricular (RV) performance. We evaluated tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE) before and after surgical correction of a CHD. STUDY DESIGN: Patients with CHD undergoing biventricular corrective surgery were included in this retrospective study...

REVIEW
Adrianus P Wijnmaalen, Katja Zeppenfeld
Radiofrequency catheter ablation (RFCA) is an important treatment modality to prevent ventricular tachycardia (VT) recurrence in patients with repaired congenital heart disease. Identification and ablation of anatomic isthmuses has improved acute ablation outcome with excellent VT-free survival in those with preserved biventricular function. Reports on RFCA for VT in patients with infiltrative disease are sparse and cardiac sarcoidosis seems to be the most prevalent cause for ventricular arrhythmia. Patients with active and ongoing inflammation are at high risk for VT recurrence...
