Tricuspid Valve Imaging and Intervention in Pediatric and Adult Patients With Congenital Heart Disease.

JACC Cardiovasc Imaging 2019 Apr;12(4):637-651

Division of Pediatric Cardiology, Mayo Clinic, Rochester, Minnesota; Division of Cardiovascular Diseases, Mayo Clinic, Rochester, Minnesota. Electronic address:

Tricuspid valve abnormalities in congenital heart disease comprise a wide spectrum, with the most common being Ebstein anomaly and tricuspid valve dysplasia. Tricuspid valve dysfunction may also be secondary to other types of congenital heart disease, including functional tricuspid regurgitation seen in right heart volume overload conditions, such as atrial septal defect and repaired tetralogy of Fallot with severe pulmonary valve regurgitation. Congenitally corrected transposition and Mustard and Senning procedures maintain the right ventricle as the systemic ventricle, and the tricuspid valve is subject to unique hemodynamic stress not typically seen in normal circulation.

The use of handheld ultrasound devices: a position statement of the European Association of Cardiovascular Imaging (2018 update).

Eur Heart J Cardiovasc Imaging 2019 03;20(3):245-252

University of Medicine and Pharmacy "Carol Davila", Euroecolab, Institute of cardiovascular diseases "Prof. Dr. C C Iliescu, Bucharest, Romania.

Recent technological advances in echocardiography, with progressive miniaturization of ultrasound machines, have led to the development of handheld ultrasound devices (HUD). These devices, no larger than some mobile phones, can be used to perform partial, focused exams as an extension to the physical examination. The European Association of Cardiovascular Imaging (EACVI) acknowledges that the dissemination of appropriate HUD use is inevitable and desirable, because of its potential impact on patient management.

Authors:
Mark K Friedberg

JACC Cardiovasc Imaging 2018 May;11(5):755-771

Labatt Family Heart Center, The Hospital for Sick Children, and Department of Paediatrics, University of Toronto, Toronto, Ontario, Canada. Electronic address:

The impact of one ventricle on the adjacent ventricle plays a key role in cardiac function. Ventricular-ventricular interactions are based on the arrangement in-series of the circulation and common pericardium, interventricular septum, and myocardial tracts. Imaging, in particular echocardiography, plays a central role in characterizing these interactions through geometric indices, septal configuration and motion, Doppler flow, timing of events in the ventricles and alterations in strain, remodeling, and diastolic filling with altered loading of the contralateral ventricle.

The association of volumetric response and long-term survival after cardiac resynchronization therapy.

Eur Heart J Cardiovasc Imaging 2017 Oct;18(10):1109-1117

Department of Cardiovascular Diseases, University Hospital Gasthuisberg, Catholic University Leuven, Herestraat 49, 3000 Leuven, Belgium.

Aims: Clinical experience indicates that limited or no reverse left ventricular (LV) remodelling may not necessarily imply non-response to cardiac resynchronization therapy (CRT). We investigated the association of the extent of LV remodelling, mechanical dyssynchrony, and survival in patients undergoing CRT.

Methods And Results: In 356 CRT candidates, three blinded readers visually assessed the presence of mechanical dyssynchrony (either apical rocking and/or septal flash) before device implantation and also its correction by CRT 12 ± 3 months post-implantation. Read More

Frequency and angiographic characteristics of coronary microvascular dysfunction in stable angina: a hybrid imaging study.

Eur Heart J Cardiovasc Imaging 2017 Nov;18(11):1206-1213

Turku PET Centre, University of Turku, Kiinamyllynkatu 4-8, 20520, Turku, Finland.

Aims: Coronary microvascular dysfunction (CMD) can cause angina in the absence of obstructive coronary artery disease (CAD). We studied the frequency and angiographic characteristics of CMD in symptomatic patients with suspected stable CAD and identified CMD as diffusely abnormal coronary vasodilator capacity by positron emission tomography (PET) perfusion imaging.

Methods And Results: We recruited prospectively 189 patients with intermediate pre-test probability of CAD who underwent coronary computed tomography angiography and quantitative 15O-water PET perfusion imaging followed by invasive coronary angiography, and assessment of fractional flow reserve when feasible.

Quantitative Assessment of Coronary Microvascular Function: Dynamic Single-Photon Emission Computed Tomography, Positron Emission Tomography, Ultrasound, Computed Tomography, and Magnetic Resonance Imaging.

Circ Cardiovasc Imaging 2017 Aug;10(8)

From the Section of Cardiovascular Medicine, Department of Internal Medicine (A.F., A.J.S.) and Department of Radiology and Biomedical Imaging (A.J.S.), Yale University School of Medicine, New Haven, CT.

A healthy, functional microcirculation in combination with nonobstructed epicardial coronary arteries is the prerequisite of normal myocardial perfusion. Quantitative assessment in myocardial perfusion and determination of absolute myocardial blood flow can be achieved noninvasively using dynamic imaging with multiple imaging modalities. Extensive evidence supports the clinical value of noninvasively assessing indices of coronary flow for diagnosing coronary microvascular dysfunction; in certain diseases, the degree of coronary microvascular impairment carries important prognostic relevance.

Derivation and Evaluation of Age-Specific Multivariate Reference Regions to Aid in Identification of Abnormal Filling Patterns: The HUNT and VaMIS Studies.

JACC Cardiovasc Imaging 2018 Mar 19;11(3):400-408. Epub 2017 Jul 19.

Department of Clinical Physiology, Västmanland County Hospital, Västerås, Sweden; Centre for Clinical Research, Uppsala University, Västmanland County Hospital, Västerås, Sweden.

Objectives: This study aimed to derive age-specific multivariate reference regions (MVRs) able to classify subjects into those having normal or abnormal filling patterns and to evaluate the prognostic impact of this classification.

Background: The integration of several parameters is necessary to diagnose disorders of left ventricular (LV) filling because no single measurement accurately describes the complexity of diastolic function. However, no generally accepted validated multiparametric algorithm currently exists. Read More

Visual and Quantitative Assessment of Coronary Stenoses at Angiography Versus Fractional Flow Reserve: The Impact of Risk Factors.

Circ Cardiovasc Imaging 2017 Jul;10(7)

From the Cardiovascular Center Aalst, Belgium (J.A., P.X., A.F., M.P., G.C., V.F., E.B., B.D.B.); and Department of Advanced Biomedical Sciences, Federico II University, Naples, Italy (E.B.).

Background: The correlation between angiographic assessment of coronary stenoses and fractional flow reserve (FFR) is weak. Whether and how risk factors impact the diagnostic accuracy of angiography is unknown. We sought to evaluate the diagnostic accuracy of angiography by visual estimate and by quantitative coronary angiography when compared with FFR and evaluate the influence of risk factors (RF) on this accuracy.
