Direct insertion of papillary muscle into mitral valve leaflets in a healthy patient without hypertrophic cardiomyopathy.

Summary of "Direct insertion of papillary muscle into mitral valve leaflets in a healthy patient without hypertrophic cardiomyopathy."

We present the case of a healthy young woman that was evaluated before participation in amateur sports. A systolic and diastolic murmur was heard during the physical examination. Two-dimensional echocardiography was performed, and a direct insertion of the posteromedial papillary muscle into the mitral valve leaflets was found. Mild mitral stenosis and moderate regurgitation were also found. Because she was asymptomatic, a follow-up in 6 months was planned to control the evaluation of her valve disease.

Contrasting Effects of Pharmacological, Procedural and Surgical Interventions on Proportionate and Disproportionate Functional Mitral Regurgitation in Chronic Heart Failure.

Two distinct pathways can lead to functional mitral regurgitation (MR) in patients with chronic heart failure and a reduced ejection fraction. When remodeling and enlargement of the left ventricle (LV...

Papillary Muscle Tugging Approximation for Functional Mitral Regurgitation.

The surgical approach is challenging for patients with severe functional mitral regurgitation with non-ischemic/ischemic dilated cardiomyopathy who are unsuitable for heart transplantation or ventricu...

Mathematical Blueprint of a Mitral Valve.

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 ...

Adjusting the neochords height for better leaflets coaptation following mitral valve repair.

Often times, in mitral valve repair techniques, the height of the newly placed Gore-Tex sutures needs correction to achieve better mitral valve leaflet coaptation or to correct systolic anterior motio...

Characteristics of mitral valve leaflet length in patients with pectus excavatum: A single center cross-sectional study.

The mitral valve morphology in patients with pectus excavatum (PE) has not been fully investigated. Thirty-five patients with PE, 46 normal controls, and patients with hypertrophic cardiomyopathy (HCM...

Comparing the Effectiveness of Repairing Versus Replacing the Heart's Mitral Valve in People With Severe Chronic Ischemic Mitral Regurgitation

People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the v...

Medical and Biotech [MESH] Definitions

Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.

Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.

Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.

A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annulus of the MITRAL VALVE. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.

Abnormal protrusion of one or more of the leaflets of TRICUSPID VALVE into the RIGHT ATRIUM during SYSTOLE. This allows the backflow of blood into right atrium leading to TRICUSPID VALVE INSUFFICIENCY; SYSTOLIC MURMURS. Its most common cause is not primary valve abnormality but rather the dilation of the RIGHT VENTRICLE and the tricuspid annulus.
