mitral

 [mi´tral]
1. shaped like a miter (tall pointed hat worn by Roman Catholic bishops).
2. pertaining to the left atrioventricular valve.
mitral valve prolapse (MVP) a condition in which some portion of the mitral valve is pushed back into the left atrium during ventricular contraction. For reasons not fully understood (there is no evident disease process) there is redundant tissue on one or both leaflets of the valve. The prolapsed portion of the valve causes a clicking sound halfway through the ventricular contraction, which is followed by a systolic murmur as blood is regurgitated back through the mitral valve into the left atrium. Echocardiography can demonstrate the mitral valve as it prolapses into the left atrium. Called also click-murmur syndrome and Barlow's syndrome.

The condition was first noted in association with potentially serious complications such as infective endocarditis, transient ischemic attack, and arrhythmias. However, in the vast majority of persons in whom mitral valve prolapse is detected by auscultation, the condition is benign and there are no other symptoms.

Mitral valve prolapse is found in persons of all ages and is fairly common, particularly in women. The few who have problems usually experience chest pain, dyspnea, palpitations, fatigue, and sometimes syncope. Electrocardiographic studies may show some premature ventricular contractions, but unlike those in coronary heart disease, these do not indicate injury to the heart muscle.

Persons who suffer from the above symptoms may require administration of a beta-adrenergic blocking agent such as propranolol, restriction of caffeine intake, and avoidance of heavy meals. Those with severe symptoms may require repair or replacement of the mitral valve. It is recommended that patients with mitral valve prolapse take antibiotics prior to dental procedures.

Patient discussion about mitral

Q. what do you do with a broken heart? I HAD A ECHO DONE THIS WEEK AND CONCLUSION WAS: 1)SEVERE MIRTAL REGURGITATION WITH LEFT ATRIAL DILATATION 2)LOW NORMAL LV FUNCTION CHEST X RAY IMPRESSION WAS: 1)NORMAL SIZE HEART WITH PROMINENT LEFT HEART BORDER. 2)PROMINENT MARKINGS WITH PROMINENT CHANGES. 3)THE BONES ARE OSTEOPENIC. BLOOD TEST....CHEMISTRY B TYPE NATRIURETIC PEPTIDE HIGH 260

A. The left atrial dilatation is likely the cause of the elevated beta natriuretic peptide. A cardiologist should be able to talk with you about dealing with the mitral valve regurgitation.

This analysis confirms the absence of a significant difference in the rate of the composite outcome of death from any cause or unplanned hospitalisation for heart failure in symptomatic patients with severe secondary mitral regurgitation treated by percutaneous mitral valve repair plus medical treatment as compared with those receiving medical treatment alone, said Prof Obadia.
In August, 2018; Mitra FR trial was published that showed that in patients with secondary MR, the rate of death or unplanned hospitalization for heart failure at 1 year did not differ significantly between patients who underwent percutaneous mitral-valve repair in addition to receiving medical therapy and those who received medical therapy alone.8 But the recently published landmark trial "COAPT - Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation trial contradicted the Mitra FR trial.
In addition, outcomes of robotic mitral valve repair are far superior to repairs done without robotic assistance.

PTMC is effective in mitral stenosis due to rheumatic fever as commissural fusion is the underlying etiology1.
"The acquisition of Cephea builds on Abbott's position in structural heart therapies and is consistent with our strategy to develop comprehensive treatments for people with mitral valve disease," said Michael Dale, vice president of Abbott's structural heart business.
The mitral valve apparatus is composed of valve leaflets, mitral annulus, chordae tendineae (CT), papillary muscles, left ventricular and atrial walls (Figure 1).
Tem sua suspeita diagnostica levantada por meio de exames de imagem, comumente por meio do ecocargiograma transtoracico, podendo ser realizado, de maneira complementar, o ecocardiograma transesofagico (RIBEIRO et al., 2012, p.314; FRANCA et al., 2013, p.372), sendo descrita como "uma massa ecodensa, arredondada, por vezes semilunar, com uma area ecoluscente em seu interior, localizada normalmente no anel posterior da valva mitral" (FRANCA et al., 2013, p.372).
Management of FMR includes optimal medical therapy, cardiac resynchronization therapy (CRT), and mitral valve surgery.
