Left ventricular diastolic function in mitral stenosis.

Echocardiography 2020 Jun 20. Epub 2020 Jun 20.

Department of Non-Invasive Cardiology, Narayana Institute of Cardiac Sciences, Bangalore, India.

The assessment of left ventricular (LV) function in the setting of mitral stenosis (MS) has been critically examined for decades. Accurate assessment of aberrations in diastolic function is important as these subjects often present with signs and symptoms of heart failure and pulmonary congestion that cannot be solely explained by the severity of mechanical obstruction. Echocardiographic evaluation of diastolic dysfunction includes an evaluation of reduced LV compliance, diminished restoring forces, and enhanced stiffness, which are challenging in the setting of MS owing to altered hemodynamic loading.

Centro Cardiologico Monzino, IRCCS and Department of Biomedical and Clinical Sciences "Luigi Sacco", University of Milan, Milan, Italy.

Transcatheter interventions for structural heart disease (SHD) now represent an effective alternative to surgery in selected patients. A clear premise is that delay in or neglect of treating patients in need of SHD intervention is associated with unavoidable morbidity and mortality because many of them have life-threatening conditions. However, the recent outbreak of coronavirus-associated disease-2019 (COVID-19) is placing an unprecedented strain on patients, physicians and world healthcare systems that resulted in deferral of elective and semi-elective procedures, such as SHD, and delay in the treatment of patients with acute coronary syndrome (ACS).

A sound knowledge of the functional anatomy of the mitral valve and the alterations caused by different diseases is indispensable for surgeons treating patients with mitral valve disease. Rheumatic mitral valve disease remains the most common heart valvular disorder in developing countries, whereas mitral regurgitation due myxomatous degeneration of the valve is the most common in developed countries. The mitral valve should be repaired whenever possible, as long as the outcome is predictably better than that of replacement. Read More

Does the Presence of Significant Mitral Regurgitation prior to Transcatheter Aortic Valve Implantation for Aortic Stenosis Impact Mortality? - Meta-Analysis and Systematic Review.

Cardiology 2020 May 27:1-11. Epub 2020 May 27.

Division of Cardiology, Rutgers Robert Wood Johnson Medical School, New Brunswick, New Jersey, USA.

Background: Mitral regurgitation (MR) is commonly encountered in patients with severe aortic stenosis (AS). However, its independent impact on mortality in patients undergoing transcatheter aortic valve implantation (TAVI) has not been established.

Methods: We performed a systematic search for studies reporting characteristics and outcome of patients with and without significant MR and/or adjusted mortality associated with MR post-TAVI. Read More

Exercise behavior of degenerative mitral stenosis.

Int J Cardiovasc Imaging 2020 May 26. Epub 2020 May 26.

Heart and Vascular Institute, Einstein Medical Center, Philadelphia, PA, USA.

Mitral annular calcification (MAC) is increasingly encountered, particularly among the elderly and those with chronic kidney disease, and is often associated with a transvalvular gradient. In contrast to rheumatic mitral stenosis relatively little is known about mitral stenosis due to MAC. We aimed to clarify whether exercise limitation in this group is primarily due to valvular obstruction or ventricular dysfunction resulting from multiple comorbidities. Read More

A Comprehensive Engineering Analysis of Left Heart Dynamics After MitraClip in a Functional Mitral Regurgitation Patient.

Front Physiol 2020 7;11:432. Epub 2020 May 7.

Tissue Mechanics Laboratory, The Wallace H. Coulter Department of Biomedical Engineering, Georgia Institute of Technology and Emory University, Atlanta, GA, United States.

Percutaneous edge-to-edge mitral valve (MV) repair using MitraClip has been recently established as a treatment option for patients with heart failure and functional mitral regurgitation (MR), which significantly expands the number of patients that can be treated with this device. This study aimed to quantify the morphologic, hemodynamic and structural changes, and evaluate the biomechanical interaction between the MitraClip and the left heart (LH) complex of a heart failure patient with functional MR using a fluid-structure interaction (FSI) modeling framework. MitraClip implantation using lateral, central and double clip positions, as well as combined annuloplasty procedures were simulated in a patient-specific LH model that integrates detailed anatomic structures, incorporates age- and gender-matched non-linear elastic material properties, and accounts for mitral chordae tethering.

Role of 3-dimensional transesophageal echocardiography in guiding transcatheter mitral valve replacement.

Echocardiography 2020 Jun 26;37(6):945-953. Epub 2020 May 26.

Houston Methodist DeBakey Heart and Vascular Center, Houston Methodist Hospital, Houston, Texas, USA.

Background: Transcatheter mitral valve replacement technologies have been developed to treat a wide range of mitral valve pathologies including primary and secondary mitral regurgitation, mitral stenosis, in addition to degenerative bioprosthetic valves and failed annuloplasty rings.

Objective: Transesophageal echocardiography, particularly with use of 3-dimensional imaging is key in successfully guiding these interventions. In this review, we highlight the key role of 3D transesophageal echocardiography in guiding TMVR, including valve-in-native valve, valve-in-prosthetic valve, valve-in-prosthetic ring, and valve-in-mitral annular calcification interventions.

Agreement between three-dimensional planimetry and mitral navigation method in the assessment of mitral valve area in rheumatic severe mitral stenosis.

Acta Cardiol 2020 May 26:1-7. Epub 2020 May 26.

Department of Cardiology, Medipol University Hospital, Istanbul, Turkey.

Rheumatic heart disease predisposes to structural changes in the mitral valve including commissural fusion and calcification with subsequent narrowing of the mitral valve orifice resulting in rheumatic mitral stenosis (RMS). To define the best therapeutic strategy, an accurate measurement of mitral valve area (MVA) for RMS is of paramount importance. The propose of the present study was to assess the agreement between the mitral navigation method (MVN) and three-dimensional (3D) planimetry in the assessment of MVA in patients with RMS. Read More

Mitral regurgitation and dyspnoea: the expanding role of mitral effective regurgitant orifice among un-selected patients.

J Cardiovasc Med (Hagerstown) 2020 Jul;21(7):503-509

Section of Cardiology, Department of Medicine, University of Verona, Verona, Italy.

Aims: Mitral regurgitation is frequent in the general population and among suspected heart failure patients; however, to what extent it contributes to dyspnoea is unclear. We hypothesized mitral regurgitation to have a role in determining dyspnoea in unselected ambulatory patients.

Methods: Consecutive outpatients referred for echocardiography were retrospectively screened and included. Read More

Left ventricular cavity obliteration: Mechanism of the intracavitary gradient and differentiation from hypertrophic obstructive cardiomyopathy.

Echocardiography 2020 Jun 22;37(6):822-831. Epub 2020 May 22.

Smidt Heart Institute, Cedars Sinai Medical Center, Los Angeles, California, USA.

Background: Controversy surrounds the cause of the pressure gradient in patients with hypertrophic obstructive cardiomyopathy (HOCM). Left ventricular cavity obliteration (LVCO) was first described as the cause of the gradient but subsequently systolic anterior motion (SAM) of the mitral valve has been established as the cause. Nevertheless, the two gradients, though different in origin and significance, share similar characteristics. Read More
