Cardiac Preload Responsiveness in Children With Cardiovascular Dysfunction or Dilated Cardiomyopathy: A Multicenter Observational Study*
Conclusions: This study provides “normal” values for global end-diastolic volume index and limits of cardiac preload responsiveness in pediatric patients with cardiovascular dysfunction and dilated cardiomyopathy: 1.33 times normal global end-diastolic volume index represents the upper limit of patent cardiac preload responsiveness, with the highest expected responsiveness being below 0.67 times normal global end-diastolic volume index. The maximum response of the Frank-Starling relationship and therefore the level of no additional preload reserve is 1.33 to 1.51 times normal global end-diastolic volume index. Above 1....

Predictors of Mortality in Pediatric Patients on Venoarterial Extracorporeal Membrane Oxygenation*
Objectives: Currently, there are no established echocardiographic or hemodynamic predictors of mortality after weaning venoarterial extracorporeal membrane oxygenation in children. We wished to determine which measurements predict mortality. Design: Over 3 years, we prospectively assessed six echo and six hemodynamic variables at 3–5 circuit rates while weaning extracorporeal membrane oxygenation flow. Hemodynamic measurements were heart rate, inotropic score, arteriovenous oxygen difference, pulse pressure, oxygenation index, and lactate. Echo variables included shortening/ejection fraction, outflow tract Doppler-derive...

Temporary right ventricular support following left ventricle assist device implantation: a comparison of two techniques
CONCLUSIONS Temporary support of the failing RV after LVAD implantation using temporary vein and the pulmonary artery RVAD is a promising therapeutic option. This approach provides adequate LVAD pre- and afterload and is associated with significantly less thromboembolic complications.

Atorvastatin improves systolic function, but does not prevent the development of dilated cardiomyopathy in streptozotocin-induced diabetic rats
Conclusions: Whereas atorvastatin does not reverse ventricular dilatation, it does have a positive hemodynamic effect on the CV system of diabetic rats. This hemodynamic benefit is independent of cholesterol levels, and is observed concomitantly with reduced oxidative stress, vascular remodeling, and improved endothelial function. Together, these results suggest that atorvastatin decreases the workload on the heart and improves systolic performance in type 1 diabetic rats by reducing oxidative stress, vascular tone, and systemic vascular resistance.

Sudden unexpected death in schizophrenia: Autopsy findings in psychiatric inpatients
In conclusion, sudden cardiac death occurs at a 0.8% rate in a psychiatric hospital, well above general population rates. Autopsy findings indicate that sudden death in schizophrenia is caused by structural cardiovascular, respiratory and neurological abnormalities, with most cases due to acute myocardial infarction. Early recognition and treatment of coronary artery disease must become a clinical priority for all adults with schizophrenia.

Anticoagulation versus placebo for heart failure in sinus rhythm.
CONCLUSIONS: Based on the two major randomised trials (HELAS 2006; WASH 2004), there is no convincing evidence that oral anticoagulant therapy modifies mortality or vascular events in patients with heart failure and sinus rhythm. Although oral anticoagulation is indicated in certain groups of patients with heart failure (for example those with atrial fibrillation), the available data does not support the routine use of anticoagulation in heart failure patients who remain in sinus rhythm.

Cardiac MRI assessment of atrial fibrosis in atrial fibrillation: implications for diagnosis and therapy
Atrial fibrillation (AF) is the most commonly encountered cardiac arrhythmia in clinical practice, with a prevalence of 0.4–1% in the US population.w1 AF is a potent risk factor, increasing the risk of stroke fivefold and accounting for approximately 15% of all strokes in the USA.w2 AF also significantly increases the risk of mortality from heart failure.w3–7 Many therapies, including pharmacological approaches and direct current cardioversion, have been tried to treat this malignant arrhythmia, but were not found to be that effective.1 w8–w11 Catheter ablation of AF has provided better outcomes compared ...

Use of Left Ventricular Assist Device (HeartMate II): A Singapore Experience
We report our experience with the HeartMate II (HMII) LVAD (Thoratec Corporation, Pleasanton, CA, USA) as a bridge‐to‐heart transplant in our center from 2009 to 2012. This was a retrospective review of 23 consecutive patients who underwent HMII LVAD implantation in our center between May 2009 and December 2012. All patients were classified as Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) levels 1 to 3 and underwent LVAD implantation as a bridge‐to‐heart transplant. There were 17 male and 6 female patients. The mean age was 43.6 years old (range 14 to 64). The etiologies of heart fa...

Successful bridge to recovery using two-stage HeartWare LVAD explantation approach after embolic stroke
A two-stage explantation of a left ventricular assist device (LVAD) was performed on 47 year old afro-american gentlemen with non-ischemic dilated cardiomyopathy (DCM) who was successfully bridged to recovery. After he suffered a stroke caused by a VAD thrombosis with embolisation, the VAD outflow graft was first ligated using minimally-invasive approach. Two months later, the device was explanted and a manufactured titanium plug was placed into the sewing ring. This stepwise procedure might be beneficial in cases of high thromboembolic risk and in patients who suffered a thromboembolic event previously.

A longer waiting game: Bridging children to heart transplant with the Berlin Heart EXCOR device—the United Kingdom experience
Conclusions: BH use in the UK has allowed significant increases in the number of children with end-stage heart failure who can be successfully bridged to transplant and the length of time they can be supported. The total number of transplants has not increased.

Anticoagulation in Patients with Dilated Cardiomyopathy, Low Ejection Fraction, and Sinus Rhythm: Back to the Drawing Board
Summary Heart failure patients present an important thrombo‐embolic risk, including symptomatic or silent peripheral arterial embolism, pulmonary embolism, and stroke. Patients in sinus rhythm who have concomitant depressed (<35%) left ventricular ejection fraction have a 4% rate of embolic events. Several prospective randomized trials of anticoagulation in this group of patients were either underpowered or had a short period of follow‐up. Even though in two studies warfarin had a slight advantage over aspirin (in the WATCH and WARCEF trials), it was at the cost of an increased risk in major hemorrhage. To decrease ...

Biventricular Finite Element Modeling of the Acorn CorCap Cardiac Support Device on a Failing Heart ORIGINAL ARTICLES: ADULT CARDIAC
Conclusions The Acorn CSD significantly reduces ED myofiber stress. However, CSD wrapped only around the LV was the only case with minimal negative effect on pump function. Findings suggest that LV-only CSD and Acorn fabric orientation should be optimized to allow maximal myofiber stress reduction with minimal reduction in pump function.

Four-dimensional blood flow-specific markers of LV dysfunction in dilated cardiomyopathy
Conclusion Despite equivalent LVSVs, HF patients with mild LV remodelling demonstrate altered diastolic flow routes through the LV and impaired preservation of inflow KE at pre-systole compared with healthy subjects. These unique flow-specific changes in the flow route and energetics are detectable despite clinical compensation, and may prove useful as subclinical markers of LV dysfunction.
