MITRAL REGURGITATION (MR)

Etiology 

Mitral valve prolapse (see below), rheumatic heart disease, ischemic heart disease with papillary muscle dysfunction, LV dilatation of any cause, mitral annular calcification, hypertrophic cardiomyopathy, infective endocarditis, congenital.



Clinical Manifestations 

Fatigue, weakness, and exertional dyspnea. Physical examination: sharp upstroke of arterial pulse, LV lift, S1 diminished: wide splitting of S2; S3; loud holosystolic murmur and often a brief early-mid-diastolic murmur due to increased transvalvular flow.

Echocardiogram 

Enlarged LA, hyperdynamic LV, identifies mechanism of MR; Doppler analysis helpful in diagnosis and assessment of severity of MR and degree of pulmonary hypertension.

MITRAL REGURGITATION TREATMENT 

For severe/decompensated MR, treat as for heart failure . IV vasodilators (e.g., nitroprusside) are beneficial for acute, severe MR. Anticoagulation is indicated in the presence of atrial fibrillation. Surgical treatment, either valve repair or replacement, is appropriate if pt has symptoms or evidence of progressive LV dysfunction [LV ejection fraction (LVEF) ≤60% or end-systolic LV diameter by echo ≥40 mm]. Operation should be carried out before development of chronic heart failure symptoms.

  1. Goji Berries... yes... I tried those too.For my health conditions, Those sweet, red berries seemed to help, but only during the time when I consumed them. I don't want to take a drug for the rest of my life, so why would I want to take a natural supplement everyday for the rest of my life (although Goji berries are very tasty and are highly nourishing). To me this was not a cure either (and I'm LOOKING for the CURE).
    Up to that point, I hadn't found a cure. I felt like a young jumbled mess. I continued to have extreme pain, but continued on my path to healing. I started to focus on myself and not everyone else. When I was a young adult, I took on too much responsibility out of a sense of obligation. This was no longer healthy for me, so I resigned from all my projects and groups. Those days to come were the best [and worst] days. I took a lot of time off work, yet began to feel so extremely exhausted. Many health professionals "diagnosed" me with adrenal fatigue & Hiv,Prostate Cancer so my situation was annoying then I keep searching for permanent cure online that's when I came to know of Dr Itua herbal center hands whom god has blessed with ancestral herbs and a gift to heal people with diseaseSo I made a purchase of his herbal medicines and I have been watching my health for 6 years now and I actually confirmed that his herbal medicines are a permanent cure and I'm so happy that I came to know of his herbal healings.You can contact Dr Itua herbal center Email: drituaherbalcenter@gmail.com www.drituaherbalcenter.com if you went through exactly what I go through in terms of health conditions because to be honest there is more to learn about natural herbs than medical drugs.
