Medina classification assigns a binary value (1,0) to the three components of a coronary bifurcation depending on whether have > (1) or < (0) 50% lesion.
Coronary bifurcations with an angle of less than 70 degrees are known as Y-shaped bifurcation and those with more than 70 degrees T-shaped bifurcation.
Rheolytic thrombectomy is done when there is contraindication to systemic thrombolysis in patients with pulmonary embolism and right ventricular dysfunction
Maximal acceptable contrast dose is calculated as 5 ml of contrast per Kg of body weight divided by the baseline serum creatinine level in mg per deciliter.
V stenting for coronary bifurcation is useful when both vessels constituting the bifurcation are involved without much involvement proximal to the carina.
