Spectral transfer function analysis of respiratory hemodynamic fluctuations predicts end-diastolic stiffness in preserved ejection fraction heart failure
Preserved ejection fraction heart failure (HFpEF) diagnosis remains controversial, and invasive left ventricular (LV) hemodynamic evaluation and/or exercise testing is advocated by many. The stiffer HFpEF myocardium may show impaired stroke volume (SV) variation induced by fluctuating LV filling pressure during ventilation. Our aim was to investigate spectral transfer function (STF) gain from end-diastolic pressure (EDP) to indexed SV (SVi) in experimental HFpEF. Eighteen-week-old Wistar-Kyoto (WKY) and ZSF1 lean (ZSF1 Ln) and obese rats (ZSF1 Ob) randomly underwent LV open-chest (OC, n = 8 each group) or closed-chest hemo...

SCAI Expert consensus statement: Evaluation, management, and special considerations of cardio‐oncology patients in the cardiac catheterization laboratory (endorsed by the cardiological society of india, and sociedad Latino Americana de Cardiologıa intervencionista)
In the United States alone, there are currently approximately 14.5 million cancer survivors, and this number is expected to increase to 20 million by 2020. Cancer therapies can cause significant injury to the vasculature, resulting in angina, acute coronary syndromes (ACS), stroke, critical limb ischemia, arrhythmias, and heart failure, independently from the direct myocardial or pericardial damage from the malignancy itself. Consequently, the need for invasive evaluation and management in the cardiac catheterization laboratory (CCL) for such patients has been increasing. In recognition of the need for a document on specia...

STEMI vs NSTEACS management trends in non-invasive hospital
Conclusion NSTEACS patients in western province of KSA present at an older age are mostly males and have higher prevalence of hypertension and hyperlipidemia compared with STEMI patients. It is therefore important to identify patients with high-risk profile and put implement measures to reduce these factors.

N-terminal-pro-brain natriuretic peptide elevations in the course of septic and non-septic shock reflect systolic left ventricular dysfunction assessed by transpulmonary thermodilution
Conclusions In septic and non-septic shock, NT-proBNP elevations reflect systolic left ventricular dysfunction and are associated with a poor outcome. They may help recognition of cardiac dysfunction in shock and its management when invasive hemodynamic monitoring is not yet instituted.

Use of intracardiac echocardiography to guide percutaneous transluminal mitral commissurotomy
ConclusionsICE‐guided PTMC offers excellent visualization of the LA and the LAA with satisfactory clinical outcomes and low risk. As a part of the PTMC procedure, ICE safely provides a valid alternative to a separate TEE procedure. © 2015 Wiley Periodicals, Inc.

Impact of cardiac output imprecision on the clinical interpretation of haemodynamic variables in the cardiac catheterisation laboratory
There is continuing concern over the accuracy and precision of cardiac output (CO) determinations [1,2]. Current guidelines require new CO monitoring devices to have a 2SD-precision of 20% (i.e. approximately 95% of measurements within 20% of their mean), which is equivalent to the averaged result of three bolus thermodilution CO measurements applied randomly over the respiratory cycle. A CO determination is the average of a number of measurements, and the greater the measurement error in CO, the greater the error transmitted to calculations of CO-derived hemodynamic variables such as stroke volume and vascular resistance.

Stenting of the left pulmonary artery after palliation of hypoplastic left heart syndrome
ConclusionsStenting of the left pulmonary artery after Norwood/Fontan palliation is safe and effective. Stents can be redilated to match somatic growth. The incidence of neointimal proliferation is extremely low and can be addressed by balloon dilation or stent implantation. © 2016 Wiley Periodicals, Inc.

The outcomes of transcatheter aortic valve replacement in a cohort of patients with end‐stage renal disease
ConclusionsPatients with ESRD who undergo TAVR are at high risk for mortality and complications. TAVR outcomes are comparable to but not substantially better than those with SAVR. Transfemoral TAVR seems to be at least as safe and effective as the current standard SAVR in patients undergoing aortic valve replacement. © 2016 Wiley Periodicals, Inc.

Life in the left atrial appendage fast lane after FDA approval: Moving forward on new technology at last
Key Points
FDA approval of the WATCHMAN is expected to spur development and availability of a range of evolutionary and revolutionary technologies for left atrial appendage occlusion.
The fourth generation WATCHMAN described in this article has multiple features that will potentially streamline the deployment process and have the potential to make left atrial appendage occlusion safer.
The population studied was too small to compare the relatively high adverse event rate with the known outcomes associated with existing WATCHMAN technology.
Going forward, in part because of improvements in technology, it is likely that lat...

Right ventricular outflow tract velocity time integral (RVOT VTI) and tricuspid regurgitation velocity/RVOT VTI ratio in pediatric pulmonary hypertension
Doppler echocardiography is a simple method of assessing hemodynamics in patients with pulmonary hypertension (PH). Determination of the right ventricular outflow tract velocity time integral (RVOT VTI) is a part of the non-invasive investigation of pulmonary flow in adults [1,2]. The normal range of RVOT VTI in adults is stable, and differences serve as indicators for changes in RV stroke volume. In children, non-invasive techniques to assess pulmonary blood flow are of interest because such investigations do not require invasive cardiac catheterization (CC) that is not without risk in PH children [3].

Survival protection by bodyweight in isolated scleroderma-related pulmonary artery hypertension
Abstract
In chronic heart failure (CHF) due to systemic cardiovascular disease, obese patients have better survival. Bodyweight versus survival was analyzed post hoc in subjects with limited scleroderma (SSc) and isolated pulmonary artery hypertension (PAH), i.e. with CHF due to pulmonary vascular disease. Rheumatologists referred scleroderma subjects for evaluation, and PAH was ascertained by right heart catheterization (RHC). Forty-nine SSc-PAH subjects were stratified by body mass index (BMI): obese 7 (14.3 %), overweight 11 (22.4 %), normal weight 21 (42.9 %), and underweight 10 (20.4 %) for 24-month follo...

Asymptomatic migration of an AMPLATZER™ Amulet™ left atrial appendage occluder through the mitral valve
An 84‐year‐old woman with a history of hemorrhagic stroke was admitted for a new cerebral ischemic event. While in hospital, she was diagnosed with paroxysmal atrial fibrillation. Owing to her high thromboembolic risk (CHA2DS2‐VASc score of 6) we performed left atrial appendage (LAA) closure using a 22‐mm AMPLATZER™ Amulet™. The procedure was successful. Systematic follow‐up with transthoracic echocardiography 8 hr later revealed that the LAA occluder had migrated and become entrapped in the mitral subvalvular apparatus. At this time, the patient was asymptomatic. The device was recovered percutaneously using...

Echocardiographic assessment of right heart function in heart transplant recipients and the relation to exercise hemodynamics
ConclusionRV systolic function is reduced in HTx patients compared with controls. 3D RVEF and 2D longitudinal deformation analysis are associated with clinical performance in stable HTx patients and seem suitable in non‐invasive routine right heart function evaluation after HTx. Invasively assessed RV systolic reserve was strongly associated with exercise capacity.This article is protected by copyright. All rights reserved.
