Right ventricular and pulmonary vascular function are influenced by age and volume expansion in healthy humans.

J Card Fail 2018 Nov 22. Epub 2018 Nov 22.

Dept. of Cardiology, Odense University Hospital, Odense, Denmark.

Background: Patients with heart failure (HF) often show signs of RV dysfunction. The function of RV coupled with the pulmonary circulation (tricuspid annular plane systolic excursion [TAPSE]: pulmonary artery systolic pressure [PASP]) has been shown to divide HF patients into distinct prognostic strata, however less is known about which factors influence this prognostic marker, and whether these factors can be modified. We sought to obtain normative values and discern the individual effects of age, gender, and fluid overload on right ventricular (RV) function. Read More

Exercise capacity in COPD patients with exercise-induced pulmonary hypertension.

Int J Chron Obstruct Pulmon Dis 2018;13:3599-3610. Epub 2018 Oct 31.

Clinic of Allergology and Respiratory Medicine, Oslo, Norway.

Background: Pulmonary hypertension (PH) in patients with COPD is associated with reduced exercise capacity. A subgroup of COPD patients has normal mean pulmonary artery pressure (mPAP) at rest, but develops high mPAP relative to cardiac output (CO) during exercise, a condition we refer to as exercise-induced pulmonary hypertension (EIPH). We hypothesized that COPD patients with EIPH could be identified by cardiopulmonary exercise test (CPET) and that these patients have lower exercise capacity and more abnormal CPET parameters compared to COPD patients with normal hemodynamic exercise response.

Swan, Ganz, and Their Catheter: Its Evolution Over the Past Half Century.

Ann Intern Med 2018 Nov;169(9):636-642

Harvard Medical School and Brigham and Women's Hospital, Boston, Massachusetts (S.P.D.).

Jeremy Swan and William Ganz developed their eponymous pulmonary artery (PA) catheter in the 1970s and, in the process, revolutionized measurement of cardiac output, pressures within the left side of the heart, and resistance in systemic and pulmonary circulations. Their invention enabled diagnostic measurements at the bedside and contributed to the birth of critical care medicine; technologic advances preceding the PA catheter generally could not be used at the bedside and required patients to be stable enough to be taken to the catheterization laboratory. Swan and Ganz worked in the same department but had quite dissimilar backgrounds and personalities. Read More

Reassessment of the Accuracy of Cardiac Doppler Pulmonary Artery Pressure Measurements in Ventilated ICU Patients: A Simultaneous Doppler-Catheterization Study.

Crit Care Med 2019 Jan;47(1):41-48

Medical Intensive Care Unit, CHU Sud Amiens, Amiens, France.

Objectives: Doppler echocardiography is a well-recognized technique for the noninvasive evaluation of pulmonary artery pressure; however, little information is available concerning patients receiving mechanical ventilation. Furthermore, recent studies have debatable results regarding the relevance of this technique to assess pulmonary artery pressure. The aim of our study was to reassess the accuracy of Doppler echocardiography to evaluate pulmonary artery pressure and to predict pulmonary hypertension. Read More

The utility of cardiac magnetic resonance imaging in post-Fontan surveillance.

Congenit Heart Dis 2018 Oct 30. Epub 2018 Oct 30.

Emory University School of Medicine, Atlanta, Georgia.

Objective: Gated cardiac MRI offers the most detailed and accurate noninvasive method of assessing cardiac anatomy, particularly in patients with complex congenital heart disease. The proposed benefits of using cMRI as a routine screening tool in the Fontan population include early recognition of asymptomatic, postoperative anatomic and physiologic changes. In 2011, we therefore instituted at our center a recommended practice of cMRI screening in patients with Fontan physiology at 3 and 8 years post-Fontan operation. Read More

Novel Noninvasive Assessment of Pulmonary Arterial Stiffness Using Velocity Transfer Function.

J Am Heart Assoc 2018 Sep;7(18):e009459

1 Division of Cardiovascular Disease Department of Medicine University of Alabama at Birmingham AL.

Background Pulmonary artery ( PA ) stiffness is associated with increased pulmonary vascular resistance ( PVR ). PA stiffness is accurately described by invasive PA impedance because it considers pulsatile blood flow through elastic PA s. We hypothesized that PA stiffness and impedance could be evaluated noninvasively by PA velocity transfer function ( VTF ), calculated as a ratio of the frequency spectra of output/input mean velocity profiles in PA s.

Mild Pulmonary Hypertension Is Associated With Increased Mortality: A Systematic Review and Meta-Analysis.

J Am Heart Assoc 2018 Sep;7(18):e009729

1 Providence Veterans Affairs Medical Center Warren Alpert Medical School of Brown University Providence RI.

Background Recent studies have demonstrated a continuum in clinical risk related to mean pulmonary artery pressure that begins at >19 mm Hg, which is below the traditional threshold used to define pulmonary hypertension ( PH ) of 25 mm Hg. Because of the implications on patient diagnosis and prognosis, the generalizability and validity of these data need further confirmation. Methods and Results Databases were searched from inception through January 31, 2018, to identify studies comparing all-cause mortality between patients with mildly elevated mean pulmonary artery pressure near but <25 mm Hg versus the referent group.

J Thorac Dis 2018 Sep;10(Suppl 24):S2882-S2889

Department of Pediatric Cardiology, Children's Hospital of New York-Presbyterian, Columbia University Medical Center, New York, NY, USA.

Atrial septal defect (ASD) is one of the most common congenital cardiac anomalies. ASD can present as an isolated lesion in an otherwise normal heart or in association with other congenital heart conditions. Regardless of the type of ASD, the direction and degree of shunting across the communication is mainly determined by the difference in compliance between the right and left ventricle. Read More
