On the chordae structure and dynamic behaviour of the mitral valve.

IMA J Appl Math 2018 Nov 30;83(6):1066-1091. Epub 2018 Aug 30.

School of Mathematics and Statistics, University of Glasgow, UK.

We develop a fluid-structure interaction (FSI) model of the mitral valve (MV) that uses an anatomically and physiologically realistic description of the MV leaflets and chordae tendineae. Three different chordae models-complex, 'pseudo-fibre' and simplified chordae-are compared to determine how different chordae representations affect the dynamics of the MV. The leaflets and chordae are modelled as fibre-reinforced hyperelastic materials, and FSI is modelled using an immersed boundary-finite element method. Read More

Mathematical Blueprint of a Mitral Valve.

Semin Thorac Cardiovasc Surg 2019 Jan 8. Epub 2019 Jan 8.

The Mitral Laboratory, Yale School of Medicine, New Haven, CT; Section of Cardiac Surgery, Department of Surgery, Yale School of Medicine, New Haven, CT. Electronic address:

Objective: Mathematical modeling tries to simplify understanding and proposes a fundamental mechanism that governs the motion and function of a complex biological system such as a mitral valve (MV) motion which represents a dynamic interplay between papillary muscle (PM) position in the context of left ventricular (LV) shape dynamics. Current therapeutic strategies to intervene on the MV may not have exploited these relationships due to lack of understanding of the interactions. We present a MV 3D mathematical model characterized by LV shape dynamics to understand fundamental working principles of ventriculo-papillary-mitral complex. Read More

Combined Percutaneous Procedure in Patient with Lutembacher Syndrome: A Case Report and Real-World Experience Review.

Cardiol Res 2018 Dec 7;9(6):385-391. Epub 2018 Dec 7.

Intervention Center, Chung-Ang University Hospital, Seoul 06973, Korea.

Even cardiac surgery has been accepted as the standard therapy for Lutembacher syndrome, a combination of congenital ostium secundum atrial septal defect (ASD) and acquired mitral valve stenosis (MVS), it also owns many limitations and disadvantages. Therefore, seeking for a less invasive therapy with the same efficacy may be worthwhile. Thanks to the development in technology and experience gaining in cardiovascular intervention, the combination of the two proved effective procedures, including percutaneous MVS treatment using balloon valvuloplasty and percutaneous ASD closure using atrial septal occluders, can be utilized as an attractive alternative therapy for these conditions.

To repair or not to repair: a case report of atrioventricular groove hematoma during mitral valve surgery.

J Cardiothorac Surg 2019 Jan 9;14(1). Epub 2019 Jan 9.

Department of Thoracic and Cardiovascular Surgery, Yokohama Sakae Kyosai Hospital, 132 Katsura-cho, Sakae-ku, Yokohama, Kanagawa, 247-8581, Japan.

Background: Atrioventricular groove hematomas during mitral valve surgery range from simple hematomas to complex atrioventricular disruptions that cause frank rupture with massive bleeding and subsequent mortality. A small or moderate-sized hematoma is reported to be present in the left atrioventricular groove in 10 to 30% of all patients immediately after mitral valve replacement. Despite the fact that atrioventricular groove hematomas are inherently unstable and unpredictable, conservative strategies are recommended due to the high mortality associated with additional surgical repair.

Carcinoid heart disease involving the left heart: a case report and biomarker analysis.

ESC Heart Fail 2019 Jan 8. Epub 2019 Jan 8.

Department of Internal Medicine, Oberndorf Hospital, Salzburg, Austria.

Herein, we report the case of a 67-year-old woman who was admitted to our hospital because of dyspnoea and oedema of the lower extremities. Transthoracic echocardiography revealed severe tricuspid and mitral regurgitation, and the leaflets of the tricuspid valve were found to be rigid and almost immobile. The plasma concentrations of serotonin and chromogranin A were elevated, and hence, suspicion for carcinoid heart disease was raised. Read More

Mechanistic insights into atrial functional mitral regurgitation: Far more complicated than just left atrial remodeling.

Echocardiography 2019 01;36(1):164-169

Icahn School of Medicine at Mount Sinai, New York, New York.

Recent studies lend credibility to the notion that lone atrial fibrillation (AF) can cause functional mitral regurgitation (MR), commonly referred to as atrial functional MR (AF-MR). The conventional view holds that left atrial enlargement associated with AF causes annular dilatation which gradually moves the mitral valve leaflets apart resulting in inadequate coaptation and regurgitation. Recent findings, however, suggest that AF-MR is not solely related to left atrial remodeling, but that important structural and functional abnormalities of the left ventricle also play a role in its pathogenesis.

Novel Left Atrioventricular Valvuloplasty for Atrioventricular Septal Defect.

Ann Thorac Surg 2018 Oct 25. Epub 2018 Oct 25.

Mt. Fuji Shizuoka Children's Hospital Department of Cardiovascular Surgery.

An infant boy with 21 trisomy was diagnosed with complete atrioventricular septal defect (CAVSD)-Rastelli type A with parachute left atrioventricular valve and absent left mural leaflet. Biventricular repair was difficult in infancy because the left ventricular volume and left atrioventricular valve annulus were too small. After two pulmonary artery bandings, the left atrioventricular valve annulus increased to 85% of normal mitral valve, and the left ventricular end-diastolic volume increased to 98% of normal.

Mitral valve repair vs replacement in elderly with degenerative disease: Analysis of the STS Adult Cardiac Surgery Database.

Ann Thorac Surg 2018 Oct 26. Epub 2018 Oct 26.

Division of Cardiac Surgery, Department of Surgery, University of Massachusetts, Medical School, Worcester, MA 01655; Department of Quantitative Health Sciences, University of Massachusetts Medical, School, Worcester, MA 01655. Electronic address:

Background: It has been postulated that mitral repair in the elderly does not confer short-term benefits over mitral replacement with complete preservation of the chordal apparatus. Our purpose was to test this hypothesis using data from the STS ACSD.

Methods: Patients age ≥ 70 undergoing primary isolated elective mitral valve repair (MVP) or mitral valve replacement (MVR) for degenerative disease were obtained from the STS ACSD v. Read More
