Materials (Basel) 2022 Jun 17;15(12). Epub 2022 Jun 17.

Institute of Cardiovascular Science, University College London, London WC1E 6BT, UK.

Mitral regurgitation is a common valvular disorder. Transcatheter edge-to-edge repair (TEER) is a minimally invasive technique which involves holding together the middle segments of the mitral valve leaflets, thereby reducing regurgitation. To date, MitraClip™ is the only Food and Drug Administration (FDA)-approved device for TEER. Read More

Echocardiography in Prone Positioned Critically Ill Patients: A Wealth of Information from a Single View.

Diagnostics (Basel) 2022 Jun 14;12(6). Epub 2022 Jun 14.

Department of Anesthesia, Intensive Care Unit and Pain Therapy, IRCCS Humanitas Clinical and Research Center, 20089 Milan, Italy.

In critically ill patients, standard transthoracic echocardiography (TTE) generally does not facilitate good image quality during mechanical ventilation. We propose a prone-TTE in prone positioned patients, which allows clinicians to obtain a complete apical four-chamber (A-4-C) view. A basic cardiac assessment can be performed in order to evaluate right ventricle function and left ventricle performance, even measuring objective parameters, i. Read More

Tricuspid Valve Prolapse: An Uncommon Pathology Revealed by TEE.

Methodist Debakey Cardiovasc J 2022 3;18(3):87-88. Epub 2022 Jun 3.

Houston Methodist DeBakey Heart & Vascular Center, Houston, Texas, US.

A 73-year-old male with a history of dilated cardiomyopathy and paroxysmal atrial fibrillation underwent transthoracic echocardiography (TTE) to evaluate for endocarditis due to fever and gram-positive cocci in chains on blood cultures. TTE revealed a 3 × 8 mm mass on the ventricular aspect of the tricuspid valve ( ). Subsequent transesophageal echocardiography (TEE) showed that the mass in question was actually myxomatous degeneration of the tricuspid valve (TV) and redundant chordae with significant valve prolapse.

Percutaneous Paravalvular Leak Repair.

Interv Cardiol Clin 2022 Jul;11(3):233-243

Division of Cardiothoracic Surgery, Banner University Medical Center, 1111 East McDowell, Phoneix, AZ 85006, USA.

Paravalvular leaks (PVLs) are challenging lesions that require a comprehensive understanding of surgical and transcatheter heart therapies, multimodality imaging, and transcatheter techniques. Approach to a transcatheter heart valve (THV) or surgical prosthesis for PVL differs in terms of options and varies according to the location (aortic or mitral). A suggested framework for transcatheter PVL repair is defect localization, access planning, defect crossing, sheath delivery. Read More

[Infective endocarditis in pregnancy: A case report].

Beijing Da Xue Xue Bao Yi Xue Ban 2022 Jun;54(3):578-580

Department of Gynecology and Obstetrics, Peking University Third Hospital, Beijing 100191, China.

Infective endocarditis in pregnancy is extremely rare in clinical practice. Guidelines addressing prophylaxis and management of infective endocarditis do not extensively deal with concomitant pregnancy, and case reports on infective endocarditis are scarce. Due to increased blood volume and hemodynamic changes in late pregnancy, endocardial neoplasms are easy to fall off and cause systemic or pulmonary embolism, respiratory, cardiac arrest and sudden death may occur in pregnant women, the fetus can suffer from intrauterine distress and stillbirth at any time, leading to adverse outcomes for pregnant women and fetuses.

Recommendations for Multimodality Cardiovascular Imaging of Patients with Hypertrophic Cardiomyopathy: An Update from the American Society of Echocardiography, in Collaboration with the American Society of Nuclear Cardiology, the Society for Cardiovascular Magnetic Resonance, and the Society of Cardiovascular Computed Tomography.

J Am Soc Echocardiogr 2022 Jun;35(6):533-569

Toronto General Hospital, Toronto, Canada.

Hypertrophic cardiomyopathy (HCM) is defined by the presence of left ventricular hypertrophy in the absence of other potentially causative cardiac, systemic, syndromic, or metabolic diseases. Symptoms can be related to a range of pathophysiologic mechanisms including left ventricular outflow tract obstruction with or without significant mitral regurgitation, diastolic dysfunction with heart failure with preserved and heart failure with reduced ejection fraction, autonomic dysfunction, ischemia, and arrhythmias. Appropriate understanding and utilization of multimodality imaging is fundamental to accurate diagnosis as well as longitudinal care of patients with HCM. Read More

A Novel Approach for Semi Automated 3D Quantification of Mitral Regurgitant Volume Reflects a More Physiologic Approach to MR.

J Am Soc Echocardiogr 2022 May 20. Epub 2022 May 20.

Philips Research (Suresnes, France).

Background: Quantification of mitral regurgitation (MR) by echocardiography is an integral to assessing lesion severity, and entails integration of multiple Doppler-based parameters. These methods are primarily founded upon the principle of PISA (proximal isovelocity surface area), a 2D method known to employ several assumptions regarding MR jet characteristics. We analyzed the results of a semi-automated method of 3D-based RV estimation which accounts for jet behavior throughout the cardiac cycle, and compared it to conventional 2D PISA methods for MR.
