Relation between invasive hemodynamics and measured glomerular filtration rate by Cr-EDTA clearance in advanced heart failure.

Scand J Clin Lab Invest 2019 Feb 20:1-8. Epub 2019 Feb 20.

a Department of Cardiology , Rigshopsitalet , Copenhagen , Denmark.

The interaction between hemodynamics and kidney function in heart failure (HF) is incompletely understood. We investigated the association between invasive hemodynamic parameters and measured glomerular filtration rate (mGFR) by plasma clearance of 51-chromium-labeled ethylenediamine tetra-acetic acid (Cr-EDTA) in patients with advanced HF and tested the hypothesis that patients with reduced mGFR have lower cardiac index (CI) and mean arterial pressure (MAP) as well as higher central venous pressure (CVP) and pulmonary capillary wedge pressure (PCWP). We retrospectively studied 242 patients (mean age 50 ± 13 years) referred for evaluation for heart transplantation or implantation of a left ventricular assist device with a left ventricular ejection fraction < 45% on optimal medical therapy, who underwent right heart catheterization (RHC) and measurement of Cr-EDTA clearance.

aVR ST Segment Elevation: Acute STEMI or Not? Incidence of an Acute Coronary Occlusion.

Am J Med 2019 Jan 9. Epub 2019 Jan 9.

University of Arizona Sarver Heart Center, Tucson. Electronic address:

Background: Identification of ST elevation myocardial infarction (STEMI) is critical because early reperfusion can save myocardium and increase survival. ST elevation (STE) in lead augmented vector right (aVR), coexistent with multilead ST depression, was endorsed as a sign of acute occlusion of the left main or proximal left anterior descending coronary artery in the 2013 STEMI guidelines. We investigated the incidence of an acutely occluded coronary in patients presenting with STE-aVR with multilead ST depression. Read More

Use of the ClearSight® System for Continuous Noninvasive Hemodynamic Monitoring during Heart Valve Interventions: Review of the Literature and Single-Site Experience.

Heart Surg Forum 2018 11 14;21(6):E476-E483. Epub 2018 Nov 14.

Institute for Pharmacology and Preventive Medicine, Cloppenburg, Germany

During interventional and structural cardiology procedures, such as mitral valve (MitraClip, BMV), aortic valve (TAVR, BAV), tricuspid valve (MitraClip), left atrial appendage (Watchman, Lariat), atrial septum (ASD/PFO closure), and coronary artery intervention (high-risk PCI), among others, patients are at a high risk of hemodynamic instability and require continuous monitoring. This is conventionally achieved through arterial catheterization and transpulmonary thermodilution. However, such invasive techniques are time-consuming and have been associated with steep learning curves, vascular complications, and increased risk of infection. Read More

Surgical Atrioventricular Valve Replacement With Melody Valve in Infants and Children.

Circ Cardiovasc Interv 2018 Nov;11(11):e007145

Department of Cardiology and Cardiac Surgery, Istituto di Ricovero e Cura a Carattere Scientifico Policlinico San Donato, Milan, Italy (V.M., S.M.E.).

Background Pediatric patients with atrioventricular valve disease have limited options for prosthetic valve replacement in sizes <15 mm. Based on successful experience with the stented bovine jugular vein graft (Melody valve) in the right ventricular outflow tract, the prosthesis has been modified for surgical valve replacement in pediatric patients with atrioventricular dysfunction with the intention of subsequent valve expansion in the catheterization laboratory as the child grows. Methods and Results A multicenter, retrospective cohort study was performed among patients who underwent atrioventricular valve replacement with Melody valve at 17 participating sites from North America and Europe, including 68 patients with either mitral (n=59) or tricuspid (n=9) replacement at a median age of 8 months (range, 3 days to 13 years).

Aortic stenosis of the neonate: A single-center experience.

J Thorac Cardiovasc Surg 2019 Jan 27;157(1):318-326.e1. Epub 2018 Sep 27.

Herma Heart Center, Division of Congenital Heart Surgery, Children's Hospital of Wisconsin, Milwaukee, Wis.

Objectives: Because data for neonates are limited, optimal management of critical aortic stenosis remains controversial (balloon valvotomy [BV] or open valvoplasty [OV]). In a center with balanced experience in both methods, we hypothesized that OV can provide a better individualized approach than blunt BV and better serve long-term outcomes.

Methods: A retrospective review of data and follow-up (survival, freedom from operation/replacement) of all neonates, suitable for biventricular repair, undergoing aortic valve procedure (1989-2015), was performed. Read More

Echocardiographic and Hemodynamic Parameters Associated with Diminishing Renal Filtration among Patients with Heart Failure with Preserved Ejection Fraction.

Cardiorenal Med 2019 13;9(2):83-91. Epub 2018 Dec 13.

Department of Medicine, Einstein Medical Center, Philadelphia, Pennsylvania, USA.

Background: Renal dysfunction is an important predictor of poor outcomes in patients with heart failure with preserved ejection fraction (HFpEF). Right ventricular (RV) dysfunction is implicated as one of the explanations for worsening renal function in cardiorenal syndrome. Novel right heart catheterization (RHC) parameters such as pulmonary artery pulsatility index (PAPi) and right atrial to pulmonary capillary wedge pressure ratio (RA:PCWP) have been found as predictors of RV dysfunction.
