Cardiology MCQ 335: Hepatoclavicular view
Hepatoclavicular view is
a) LAO 40 / cranial 40
b) RAO 40 / caudal 40
c) LAO 40 / caudal 40
d) RAO 40 / cranial 40
["Click here for the answer with explanation", "Correct Answer:"]
a) LAO 40 / cranial 40
Hepatoclavicular view for angiocardiography is named so to describe to direction of the x-ray beam from the liver below to the left clavicle above. It is a shallower (LAO 40 degree) long axial oblique view with steeper (40 degree) cranial angulation. This view images the posterior aspect of ventricular septum in the atrioventricular (AV) canal region. The common AV valve can be visualised angiographically in this vie...

Cardiology MCQ 338: Hydration prior to angio
Hydration prior to contrast angiography is useful to:
a) Reduce the chance of contrast nephropathy
b) Reduce the chance of thrombotic episodes in cyanotics
c) Reduce the chance of pulmonary edema
d) a and b are true
["Click here for the answer with explanation", "Correct Answer:"]
d) a and b are true
Good hydration prior to contrast angiography is useful in reducing the chance of contrast induced nephropathy. As dehydration which occurs due to osmotic diuresis after contrast angiography can predispose to thrombotic episodes in those with cyanotic congenital heart diseases with polycythemia, adequate pre-procedure hyd...

a) Posteroseptal pathway
b) Anteroseptal pathway
c) Left lateral pathway
d) Right lateral pathway
["Click here for the answer with explanation", "Correct Answer:"]
a) Posteroseptal pathway
Negative delta wave and QRS in II, III and aVF suggests posteroseptal pathway (Ref: Algorithm in Figure 35-19, Libby: Braunwald’s Heart Disease, 8th Edition).

Cardiology MCQ 343: Mechanism of action of ranolazine
Anti-ischemic mechanism of action of ranolazine is by:
a) Negative inotropic effect
b) Positive inotropic effect
c) Negative lusitropic effect
d) Positive lusitropic effect
["Click here for the answer with explanation", "Correct Answer:"]
d) Positive lusitropic effect
Ranolazine is thought to have its antianginal action by preserving myocardial blood flow during ischemia by its effects on inhibition of late sodium current which in turn prevents cellular sodium overload and sequentially calcium overload. Prevention of calcium overload reduces compression of intramyocardial blood vessels by reducing diastolic myocardia...
