Late gadolinium enhancement CMR in primary mitral regurgitation

Mitral regurgitation (MR) is the second most prevalent valve disease in Europe after aortic stenosis and its origin is pre-dominantly degenerative [1]. The appropriate timing for sur-gical intervention in severe asymptomatic primary MR with preserved left ventricular (LV) function remains controversial [2].

Primary mitral valve regurgitation due to degenerative valve disease is the second most common form of valvular heart disease in the Western world.1 The consequence of mitral regurgitation (MR) is left ventricular (LV) and left atrial (LA) volume overload with dilatation of cardiac chambers and eventually dysfunction of affected chambers. LV and LA

2. Degenerative mitral valve disease PR - CMVPR

Mitral regurgitation can be clearly identified on color-flow Doppler. Tricuspid valve prolapse and regurgitation are also commonly seen. Pulmonary hypertension, evidenced by an increased tricuspid regurgitation velocity, often develops as CHF advances. The E wave from mitral inflow is often increased, as is the E:E (or some prefer the E:IVRT).

When Do You Worry About Mitral Regurgitation?

Chronic Mitral Regurgitation Etiologies CAUSES Degenerative MR (also known as primary or organic MR) is usually due to an anatomic abnormality of the mitral valve itself, including the leaflets, and/or the subvalvular apparatus, such as the chordae or papillary muscles. Functional MR (also known as secondary MR) is the result of left

Aims The management of asymptomatic patients with mitral regurgitation (MR) remains controversial. Exercise-induced pulmonary hypertension (ExPHT) was recently reported as a strong predictor of rapid onset of symptoms. We hypothesised that ExPHT is a predictor of postoperative cardiovascular events in patients with primary MR.

Mitral Regurgitation Due to Degenerative Mitral-Valve Disease

Volume overload due to mitral regurgitation leads to left atrial and left ventricular dilatation. When the severity of mitral regurgitation increases acutely, the pressure in the small, normal left atrium abruptly rises, causing an increase in pulmonary venous pressures, with pulmonary edema. In contrast, when mitral regurgitation

Degenerative Mitral Valve Disease - Accueil

Degenerative mitral valve disease Degenerative mitral valve disease (DMVD)(previously named myxomatous mitral valve degeneration or mitral valve endocardiosis) is the most commonly encountered cardiopathy in dogs. This disease is characterized by the appearance of nodules on the free edges of the valve and a thickening of the chordae tendinae.

Exercise testing is helpful in many situations (4) for determining if a patient is truly asymptomatic and in identifying those who develop pulmonary hypertension with exercise (60 mm Hg) (1,2).

Management of Asymptomatic Severe Degenerative Mitral

The decision for surgery in the management of asymptomatic severe degenerative mitral regurgitation (MR) is about doing the right thing at the right time and place. European and American guidelines have provided us with guidance on surgical indications, albeit with different levels of recommendations.

Exercise Pulmonary Hypertension in Asymptomatic Degenerative

Conclusions Exercise PHT is frequent in patients with asymptomatic degenerative mitral regurgitation. Exercise mitral regurgitation severity is a strong independent predictor of both exercise SPAP and exercise PHT. Ex-ercise PHT is associated with markedly low 2-year symptom-free survival, emphasizing the use of exercise echocardiography.
