Anti-Streptococcal Vaccine: Mutations can occur in weeks, making the vaccine ineffective. Hence an effective anti streptococcal vaccine for prevention of rheumatic fever it difficult to develop.
Peripheral signs of aortic regurgitation (AR) are mostly due to the high stroke volume and high pulse pressure. These are features of aortic run off and can occur
CXR showing dilated RVOT Chest X-ray PA view showing a bulge along the left border, below the aortic knuckle and pulmonary bay. Sternal wires are seen near the mid line, which would
E-CPR improves pediatric cardiopulmonary arrest survival Cardiopulmonary arrest survival: Extracorporeal Cardiopulmonary Resuscitation (E-CPR) using extracorporeal membrane oxygenator (ECMO) has been in use for resuscitation of refractory cardiac arrest
Coronary steal The term ‘coronary steal’ (CS) is basically diversion of coronary flow from one artery to another. It can be either between from one coronary territory to
Reverse pulsus paradoxus Reverse pulsus paradoxus is an expiratory fall in pulse volume, the opposite of pulsus paradoxus. The classical causes of reverse pulsus paradoxus described are [1]:
Pulsus paradoxus Pulsus paradoxus is the exaggeration of inspiratory fall in pulse volume and in an extreme case the pulse may disappear in inspiration (pulsus paradoxus totalis). The
Diastolic pulsus alternans Though there is no pulse felt in diastole, diastolic pulsus alternans (DPA) has been described as the alternation of mitral inflow velocities. In one case
Biventricular pulsus alternans (BVPA) Pulsus alternans is alternating volume of pulse, with a regular rhythm, mostly seen with severe left ventricular dysfunction. Biventricular and right ventricular pulsus alternans
