Coronary Microvascular Dysfunction: Clinical Considerations and Noninvasive Diagnosis.

JACC Cardiovasc Imaging 2019 Apr 11. Epub 2019 Apr 11.

University of Maryland School of Medicine, Department of Diagnostic Radiology and Nuclear Medicine, Baltimore, Maryland.

Chest pain in patients without obstructive coronary artery disease has been realized as a frequent problem encountered in clinical practice. Invasive flow investigations have suggested that up to two-thirds of patients with nonobstructive coronary atherosclerosis may have microvascular dysfunction (MVD). Positron emission tomography myocardial perfusion imaging in conjunction with tracer-kinetic modeling enables the concurrent quantification of myocardial blood flow (MBF) in milliliters per minute per gram of tissue.

Sherif F Nagueh

JACC Cardiovasc Imaging 2019 Apr 11. Epub 2019 Apr 11.

Methodist DeBakey Heart and Vascular Center, Houston Methodist, Houston, Texas. Electronic address:

Left ventricular diastolic function plays an important role in determining left ventricular filling and stroke volume. Abnormal diastolic function has been recognized in many cardiovascular diseases and is associated with worse outcomes, including total mortality and hospitalizations due to heart failure. Using echocardiography, it is possible to diagnose the presence of diastolic dysfunction and the pathophysiologic mechanisms involved as they affect left ventricular and left atrial structure and function.

Morphological Assessment of the Tricuspid Apparatus and Grading Regurgitation Severity in Patients With Functional Tricuspid Regurgitation: Thinking Outside the Box.

JACC Cardiovasc Imaging 2019 Apr;12(4):652-664

Department of Cardiac, Thoracic, and Vascular Sciences, University of Padua School of Medicine, Padua, Italy; IRCCS, Instituto Auxologico Italiano, S. Luca Hospital, University of Milano-Biococca, Milan, Italy.

Current guidelines recommend transthoracic echocardiography to assess patients with functional tricuspid regurgitation (FTR) because it provides information regarding the presence of structural abnormalities of the tricuspid valve (TV), allows measurement of tricuspid annulus diameter, and evaluates severity of FTR by integrating data obtained from 2D and Doppler echocardiography. Critical components of the noninvasive evaluation include information regarding TV anatomy, tricuspid regurgitation severity, right ventricular size and systolic function, and associated findings such as estimated pulmonary artery pressure. However, most of the parameters included in the current recommendations to assess FTR are derived from the experience and knowledge developed about the mitral valve and have been transferred from the left to the right side of the heart without accounting for differences in anatomy of the tricuspid and mitral apparatus or for differences in hemodynamic environment in which the TV operates compared to its left counterpart.

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.

Tricuspid Regurgitation: Predicting the Need for Intervention, Procedural Success, and Recurrence of Disease.

JACC Cardiovasc Imaging 2019 Apr;12(4):605-621

NewYork-Presbyterian Hospital, Columbia University Medical Center, New York, New York.

Interest in tricuspid valve pathology has rapidly expanded in response to reported poor clinical outcome for functional tricuspid regurgitation and the limited indications and options for treatment. In the past few years, different transcatheter technologies have emerged as alternatives to conventional surgery to serve this untreated high-risk population. In this review, the authors explore the indications for intervention in tricuspid regurgitation according to current guidelines, the published research to support the expansion of these indications including the role of transcatheter interventions, and the risk factors for therapy failure, which may help define the appropriate patient population for treatment.

Imaging Risk in Multisystem Inflammatory Diseases.

JACC Cardiovasc Imaging 2019 Mar 8. Epub 2019 Mar 8.

Second Cardiology Department, Attikon Hospital, Medical School, National and Kapodistrian University of Athens, Greece.

Rheumatic diseases are immune-mediated inflammatory multisystem diseases with frequent cardiovascular manifestations including perimyocarditis, valvular disease, coronary artery disease, heart failure with or without preserved ejection fraction, pulmonary hypertension, aneurysms, and thrombosis. Echocardiography, carotid ultrasonography, cardiac computed tomography, cardiac magnetic resonance imaging, and positron emission tomography are valid diagnostic tools for the detection of the cardiovascular complications of the multisystem diseases that frequently determine prognosis. Furthermore, the findings of these methods may offer additive risk stratification in asymptomatic patients over the conventional risk scores used to assess cardiovascular risk in the primary prevention setting.
