Quantitative Analysis of Right Ventricular (RV) Function With Echocardiography in Chronic Heart Failure With No or Mild RV Dysfunction: Comparison With Cardiac Magnetic Resonance Imaging
Conclusions— Echocardiographic RV performance parameters (tricuspid annular plane systolic excursion, systolic longitudinal velocity, tissue strain, and 2D strain) correlated with the MRI-calculated RVEF and overall predicted it. In particular, RV 2D strain and tissue strain were good markers for RV longitudinal motions. These echocardiographic parameters are easily obtained and may give important information about RV function for evaluation and prognostic stratification of patients with heart failure.

Arterial-Pressure-Based Cardiac Output Analysis Reveals the Usefulness of Pericardiocentesis
Cardiac tamponade can develop as a complication of pericardial effusion and needs urgent invasive intervention, such as pericardiocentesis.1,2 Reports on hemodynamic changes during pericardiocentesis in humans are limited. Previous studies have measured changes in cardiac output (CO) and stroke volume (SV) using invasive pulmonary artery catheterization, once the pericardial effusion has been treated. More recently developed techniques, such as the FloTrac/Vigileo system (Edwards Lifesciences, Irvine, CA), enable continuous measurement of CO and SV less invasively, using pulse contour analysis.

Renal Extraction and Acute Effects of Glucagon-like peptide-1 on Central and Renal Hemodynamics in Healthy Men.
Abstract The present experiments were performed in order to elucidate the acute effects of intravenous infusion of glucagon-like peptide (GLP-1) on central and renal hemodynamics in healthy men. Seven healthy middle-aged men were examined on two different occasions in random order. During a 3-hour infusion of either GLP-1 (1.5 pmol kg-1 min-1) or saline, cardiac output was estimated non-invasively, and intra-arterial blood pressure and heart rate were measured continuously. Renal plasma flow, glomerular filtration rate, and uptake/release of hormones and ions were measured by Fick's Principle after catheterization...

Impact of postoperative acute kidney injury on clinical outcomes after transcatheter aortic valve implantation: A meta‐analysis of 5,971 patients
ConclusionsPostoperative AKI seems to significantly worsen TAVI prognosis. The results of the present meta‐analysis should be considered hypothesis‐generating and future studies on risk stratification, prevention, and postoperative management are needed. © 2015 Wiley Periodicals, Inc.

Predictors of Long-term Clinical Endpoints in Patients With Refractory Angina Coronary Heart Disease
Conclusions Clinically stable patients with RA who are medically managed have a modest mortality, but a high incidence of hospitalization and resource use over 3 years. These findings point to the need for novel therapies aimed at symptom mitigation in this population and their potential impact on health care utilization and costs.

Right ventricular reserve in a piglet model of chronic pulmonary hypertension
Right ventricular (RV) response to exercise or pharmacological stress is not well documented in pulmonary hypertension (PH). We investigated the relationship between RV reserve and ventricular–arterial coupling. Surgical ligation of the left pulmonary artery was performed in 13 Large White piglets (PH group), thereafter weekly embolisations of the right lower lobe were performed for 5 weeks. A control group of six piglets underwent sham procedures. Right heart catheterisation and echocardiography were performed at week 6. Pressure–volume loops were recorded before and after dobutamine infusion. Induction o...

Accuracy of Echocardiographic Cardiac Index Assessment in Subjects with Preserved Left Ventricular Ejection Fraction
ConclusionsIn subjects with nondilated left ventricles with preserved LVEF, flow‐ or volume‐based measures of CI by 2D echocardiography may not accurately reflect CI (TD) and CI (F). Further larger studies are required to verify our findings and to evaluate the accuracy of contrast and 3D echocardiography in this setting.

Temporal trends and patterns in percutaneous treatment of coronary artery disease in Poland in the years 2005-2011.
CONCLUSIONS: Use of modern attributes of interventional cardiology like DES stents, radial approach and treatment of higher risk patients has increased in Poland in 2005 to 2011. The adoption of Stent For Life initiative has resulted in increasing number of percutaneous coronary procedures over the years. PMID: 25733178 [PubMed - as supplied by publisher]

PFO closure with only fluoroscopic guidance: 7 years real‐world single centre experience
ConclusionsIn our experience Fluoro‐G PFO closure was performed mainly in cases of simple anatomy, with similar results in terms of safety and efficacy compared to Echo‐G cases. Both fluoroscopy and total procedural times were lower in the Fluo‐G cases. © 2014 Wiley Periodicals, Inc.

Effects of Withdrawing Versus Continuing Renin-Angiotensin Blockers on Incidence of Acute Kidney Injury in Patients with Renal Insufficiency Undergoing Cardiac Catheterization: Results from the CAPTAIN Trial
Conclusion In patients with moderate renal insufficiency undergoing cardiac catheterization, withholding ACEI/ARB reduced (without statistical significance) the incidence of contrast-induced AKI. Additionally, a lower rise in post procedural creatinine levels was also noted. This low cost intervention could be considered when referring a patient for cardiac catheterization.

Association of embolism and stroke in the catheterization laboratory
Key Points Strokes continue to be a rare but potentially devastating event during cardiac catheterization Most strokes are associated with brain imaging patterns consistent with embolic etiologies Common embolic etiology supports not only the critical importance of catheterization laboratory techniques to minimize activation of thrombosis or embolism, but also point to potential treatment with rapid application of neurovascular brain salvage techniques.
