Optimal Number of Heartbeats Required for Representing Left Chamber Volumes and Function in Patients with Rate-Controlled Atrial Fibrillation.

J Am Soc Echocardiogr 2019 Feb 1. Epub 2019 Feb 1.

Department of Laboratory and Transfusion Medicine, University of Occupational and Environmental Hospital, Kitakyushu, Japan. Electronic address:

Background: The optimal number of heartbeats required for representing left heart chamber function in patients with atrial fibrillation (AFib) has not been extensively studied.

Methods: To determine the optimal number, we performed an automated quantification analysis of three-dimensional echocardiography (3DE) data sets in 93 patients with AFib for whom 10-20 consecutive one-beat full-volume 3DE data sets were acquired twice. We measured left ventricular end-diastolic volume (LVEDV), left ventricular ejection fraction (LVEF), and maximal left atrial volume (LAVmax) in each heartbeat; each parameter was averaged using a serial number of heartbeats randomly selected, and these values were compared with the averaged value obtained from the entire set of heartbeats.

Pathophysiology and Echocardiographic Diagnosis of Left Ventricular Diastolic Dysfunction.

J Am Soc Echocardiogr 2019 Feb;32(2):216-232.e2

Icahn School of Medicine at Mount Sinai, New York, New York. Electronic address:

Echocardiography is the primary imaging modality used for the clinical evaluation of left ventricular (LV) diastolic function. Using two-dimensional together with transmitral, mitral annular, and pulmonary venous Doppler data, conclusions may be drawn regarding the relaxation and compliance properties of the ventricle that can be used for estimating LV filling pressure. Echocardiographic estimation of LV filling pressure has been shown to be especially useful for evaluating patients with dyspnea of unknown etiology as well as those with heart failure with preserved ejection fraction.

Accuracy of Jet Direction on Doppler Echocardiography in Identifying the Etiology of Mitral Regurgitation in Obstructive Hypertrophic Cardiomyopathy.

J Am Soc Echocardiogr 2018 Dec 28. Epub 2018 Dec 28.

Department of Cardiovascular Medicine, Mayo Clinic, Rochester, Minnesota.

Background: Mitral valve regurgitation (MR) mediated by systolic anterior motion (SAM) in obstructive hypertrophic cardiomyopathy (HCM) is traditionally characterized by a posteriorly directed jet on Doppler echocardiography. Many believe that MR in the absence of a posteriorly directed jet signals the presence of intrinsic mitral valve (MV) disease.

Methods: A total of 709 adult patients with obstructive HCM who underwent septal myectomy were evaluated; 330 of these patients had >2 + MR preoperatively and constituted the study group. Read More

Colette Veyrat

J Am Soc Echocardiogr 2018 Dec;31(12):1308-1322

Centre National de la Recherche Scientifique Honorary Researcher, Paris, France. Electronic address:

In 1968, while cardiologists were focused on cardiac structures imaged by ultrasound, Daniel Kalmanson in Paris, France, devised a new ultrasonic modality, directional continuous-wave Doppler, enabling him to record instantaneous cardiovascular blood flow velocities with recognition of their direction (relative to the transducer) in vessels. An innovative presentation of Doppler data also made velocity traces physiologically understandable. Following the noninvasive study of the arterial and venous beds, flow velocity in the right (1969) and left (1970) cardiac chambers was studied by means of a directional Doppler catheter. Read More

Echocardiographic Assessment for the Detection of Cardiotoxicity Due to Vascular Endothelial Growth Factor Inhibitor Therapy in Metastatic Renal Cell and Colorectal Cancers.

J Am Soc Echocardiogr 2019 Feb 17;32(2):267-276. Epub 2018 Nov 17.

Department of Cardiovascular Medicine, Mayo Clinic, Rochester, Minnesota; Division of Cardiology, Department of Medicine, Dalhousie University, Halifax, Nova Scotia, Canada. Electronic address:

Background: Cardio-oncology is a recently established discipline that focuses on the management of patients with cancer who are at risk for developing cardiovascular complications as a result of their underlying oncologic treatment. In metastatic colorectal cancer (mCRC) and metastatic renal cell carcinoma (mRCC), vascular endothelial growth factor inhibitor (VEGF-i) therapy is commonly used to improve overall survival. Although these novel anticancer drugs may lead to the development of cardiotoxicity, whether early detection of cardiac dysfunction using serial echocardiography could potentially prevent the development of heart failure in this patient population requires further study.
