Correlation and agreement between 2D and 3D speckle-tracking echocardiography for left ventricular volumetric, strain, and rotational parameters in healthy volunteers and in patients with mild mitral stenosis.

Echocardiography 2019 Apr 19. Epub 2019 Apr 19.

Department of Cardiology, Dr. Siyami Ersek Cardiovascular and Thoracic Surgery Research and Training Hospital, Istanbul, Turkey.

Background: Recent advances had allowed measurement of myocardial deformation parameters using 3D speckle-tracking echocardiography (STE). Agreement between these two modalities and interchangeability of findings remain as an issue since 2DSTE is more widely available than 3DSTE. The aim of this study was to investigate the correlation and agreement between 2DSTE and 3DSTE in healthy volunteers and in patients with mild mitral stenosis (MS). Read More

Mitral valve stenosis after transcatheter aortic valve replacement: Case report and review of the literature.

Cardiovasc Revasc Med 2019 Mar 1. Epub 2019 Mar 1.

Interventional Cardiology Unit, Cardio Center, Humanitas Research Hospital, Rozzano-Milano, Italy.

Mitral stenosis is a rare and potentially severe complication of transcatheter aortic valve replacement (TAVR). Given the anatomic coupling and interdependence of the aortic and mitral valves, it comes by itself that procedures (either surgical or percutaneous) involving the aortic valve imply the risk of altering mitral valve function. Indeed, transcatheter aortic prostheses may impair adequate anterior mitral leaflet (AML) opening, especially when implanted in a "low" position, thus resulting in high transvalvular gradients.

Undiagnosed hypertrophic obstructive cardiomyopathy during transcatheter aortic valve replacement: a case report.

J Med Case Rep 2018 Dec 18;12(1):372. Epub 2018 Dec 18.

Department of Anesthesiology, University of Florida College of Medicine, Gainesville, Florida, USA.

Background: Transcatheter aortic valve replacement is indicated for severe symptomatic aortic stenosis in patients who have a very high or prohibitive surgical risk as assessed pre-procedurally by the Society of Thoracic Surgery Risk Score, EuroSCORE (II), frailty testing, and other predictors. When combined with another left ventricular outflow tract obstruction, careful consideration must be taken prior to proceeding with transcatheter aortic valve replacement because an additional masked left ventricular outflow tract pathology can lead to challenging hemodynamics in the peri-deployment phase, as reported in this case.

Case Presentation: A 56-year-old Caucasian man with multiple comorbidities and severe aortic stenosis underwent transcatheter aortic valve replacement under monitored anesthesia care. Read More

Intermittent malfunction and regurgitation of a mitral prosthetic valve due to entrapment by a residual subvalvular apparatus.

Echocardiography 2018 12 1;35(12):2092-2094. Epub 2018 Nov 1.

Department of Cardiology, Kosuyolu Kartal Training and Research Hospital, Istanbul, Turkey.

Intermittent malfunction is a rare but potentially serious complication of prosthetic heart valve (PHV) replacement. It may be observed in both mitral and aortic valve prosthesis and may lead to either paroxysmal obstruction or regurgitation, depending on the valve location and on the phase of the cardiac cycle during which the leaflet is entrapped. The most frequently encountered causes of intermittent valve malfunction are pannus formation, prosthetic valve thrombosis, vegetations, and remnants of subvalvular apparatus such as chordae tendineae and suture material.

Melody valve in mitral position: Complete fracture causing acute mitral stenosis in a child.

Catheter Cardiovasc Interv 2019 Feb 31;93(2):E101-E104. Epub 2018 Oct 31.

Division of Pediatric Cardiology, Mayo Clinic, Rochester, Minnesota.

We present a case of a 7-year-old boy with a history of multiple mitral valve interventions and subsequent Melody valve placement in the mitral position, who presented with acute mitral stenosis due to complete fracture of the Melody stent. He was born early with severe mitral and tricuspid insufficiency due to valvular dysplasia, and ended up with 4 sternotomies before the age of 2 due to mitral valve dysfunction and recurrent prosthetic valve thrombosis. He then developed mixed stenosis and regurgitation at age 6, and to avoid another sternotomy, valve-in-valve therapy with off-label use of a 20-mm Melody valve was done with hybrid procedure via trans-apical approach.

The Integration of Doppler Ultrasound With Two-Dimensional Echocardiography and the Noninvasive Cardiac Hemodynamic Revolution of the 1980s.

J Am Soc Echocardiogr 2018 Dec 16;31(12):1353-1365. Epub 2018 Oct 16.

Department of Cardiovascular Medicine, Mayo Clinic, Rochester, Minnesota. Electronic address:

In the 1970s, as cardiac imaging matured from M-mode to two-dimensional echocardiography, investigators in Norway showed that continuous-wave Doppler ultrasonography could be used to accurately measure the mean gradient and pressure half-time for stenotic mitral valves. In the 1980s, continuous-wave Doppler was validated for measurement of the pressure gradient across stenotic aortic valves, and pulsed-wave Doppler combined with two-dimensional echocardiographic imaging was validated for noninvasive measurement of stroke volume and cardiac output. The combination of stroke volume measurement and measurement of the time-velocity integral of flow through the aortic valve was then validated as a means to accurately calculate valve area for patients with stenotic aortic valves or aortic prostheses.

Pre-intervention morphologic and functional echocardiographic characteristics of neonates with critical left heart obstruction: a Congenital Heart Surgeons Society (CHSS) inception cohort study.

Eur Heart J Cardiovasc Imaging 2018 Oct 17. Epub 2018 Oct 17.

Department of Pediatrics, Division of Cardiology, The Hospital for Sick Children, 555 University Ave, Toronto, ON M5G 1X8, Canada.

Aims: The aims of this study were to provide a detailed descriptive analysis of pre-intervention morphologic and functional echocardiographic parameters in a large, unselected, multicentre cohort of neonates diagnosed with critical left heart obstruction and to compare echocardiographic features between the different subtypes of left-sided lesions.

Methods And Results: Pre-intervention echocardiograms for 651 patients from 19 Congenital Heart Surgeons' Society (CHSS) institutions were reviewed in a core lab according to a standardized protocol including >150 morphologic and functional variables. The four most common subtypes of lesions were: aortic atresia (AA)/mitral atresia (MA) (29% of patients), AA/mitral stenosis (MS) (20%), aortic stenosis (AS)/MS (26%), and isolated AS (iAS) (18%).

A novel, data-driven conceptualization for critical left heart obstruction.

Comput Methods Programs Biomed 2018 Oct 20;165:107-116. Epub 2018 Aug 20.

Labatt Family Heart Centre, The Hospital for Sick Children, Toronto, CA ; Division of Pediatric Cardiac Surgery, Arnold Palmer Children's Hospital, Orlando, FL ; Department of Pediatrics, University of Toronto, Toronto, CA . Electronic address:

Background: Qualitative features of aortic and mitral valvar pathology have traditionally been used to classify congenital cardiac anomalies for which the left heart structures are unable to sustain adequate systemic cardiac output. We aimed to determine if novel groups of patients with greater clinical relevance could be defined within this population of patients with critical left heart obstruction (CLHO) using a data-driven approach based on both qualitative and quantitative echocardiographic measures.

Methods: An independent standardized review of recordings from pre-intervention transthoracic echocardiograms for 651 neonates with CLHO was performed. Read More

Watch out for left atrial roof thrombus.

Ann Card Anaesth 2018 Oct-Dec;21(4):446-447

Division of Cardiovascular and Thoracic Anesthesiology, Seth GSMC and KEM Hospital, Mumbai, Maharashtra, India.

Rheumatic mitral stenosis is often associated with thrombus formation in the left atrium (LA), especially in patients with atrial fibrillation. Although thrombus can occur anywhere within the LA, the most common site is the left atrial appendage. Therefore, it is important to carefully screen the entire LA during perioperative transesophageal echocardiography to exclude thrombus. Read More

Computer simulated "Virtual TAVR" to guide TAVR in the presence of a previous Starr-Edwards mitral prosthesis.

J Cardiovasc Comput Tomogr 2019 Jan - Feb;13(1):38-40. Epub 2018 Oct 9.

Department of Cardiology, Morriston Hospital and Swansea University Medical School, Swansea, United Kingdom.

Background: We evaluated the utility of the HeartNavigator III software (Philips Healthcare, Netherlands) to create a patient specific three-dimensional model using ECG-gated CT images to plan Transcatheter Aortic Valve Replacement (TAVR) in a patient with previous Starr-Edwards mitral prosthesis.

Methods: A patient with a previous Starr-Edwards mitral prosthesis considered too high risk for conventional surgery required TAVR. It was uncertain whether this would be possible whilst avoiding the complication of the aortic prosthesis interacting with the high-profile Starr-Edwards cage and ball valve mechanism. Read More
