Not a single drop of blood can ever leak from our ventricle to atria in entire life time. During the phase of systole, left ventricle will generate force to send blood into aorta. This will also put substantial stress on mitral valve leaflets but the bicuspid mitral valve leaflets are able to hold their position allRead More
40-21 rule for duration of prophylaxis Rheumatic fever is the cause of heart disease of poverty. It is caused by type II hypersensitivity reaction/ molecular mimicry where antibodies against group A beta hemolytic streptococci cross react with N acetyl glucosamine which is present in endothelium of heart valves, synovium, basal ganglia and skin. Usual course ofRead More

#NEETPG #INICET #FMGE 2 min read You have a patient on central Line in ICU who deteriorates suddenly with crashing of BP due to large of amount of air entering right side of the heart. The large air bubbles will crowd and occlude the flow of blood into pulmonary artery. This leads to crashing of BP.Read More
#CausesofTricuspid #TricuspidRegurgitation #TricuspidPrevent Causes of Tricuspid Regurgitation Mnemonic: Functional REP-C Functional dilatation of tricuspid annulus due to RVF R: Rheumatic heart disease, Radiation E: Endomyocardial fibroelastosis and Ebstein anomaly (Lithium teratogenicity) P: Pulmonary artery hypertension severe causing RVF P: Pacing lead induced damage C: Carcinoid syndrome Clinical features Effort intolerance due to less pulmonary bloodRead More
Tricuspid stenosis Key pick up points – Large a waves in JVP – Blunted Y descent in JVP – Mid-diastolic murmur – Pulsations in liver Tricuspid stenosis can coexist with mitral stenosis and usually manifests after the Percutaneous mitral valvotomy has been done. Patient will develop features of right sided heart failure. Symptoms Ankle edema AbdominalRead More
