Coronary stents dislodged or embolized prior to complete expansion in the target vessel may be retrieved with special devices such as snares, baskets and embolization protection devices.1,2 Rare cases of partially expanded or fractured stents extract…
Percutaneous coronary intervention of bifurcation lesions is associated with lower procedural success rates and an increased incidence of subsequent major adverse cardiac events and restenosis.1,2 Several reasons may be offered. The implantation of a…
Cardiogenic shock is a devastating complication of acute myocardial infarction (MI) with an in-hospital mortality between 40–76%.1,2 Cardiogenic shock from right ventricular infarction is uncommon, though it has a mortality rate equal to that of left…
Coronary arteries are usually located on the surface of the cardiac muscle. Myocardial bridges have been described in a variable number of autopsy cases ranging from 5.4% to 85.7% of cases examined, depending on the population sampled.1,2 In contrast…
Contrast media plays an important role in defining coronary anatomy in diagnostic and interventional cardiac catheterization procedures as well as in radiology. Iodine-containing compounds have been shown to have radio-opaque properties that attenuat…
Ductal origin of the distal pulmonary artery1 is characterized by a patent ductus arteriosus in continuity with the proximal end of a pulmonary artery (either left or right, or both) with no continuity to the main pulmonary artery (PA). Progressive c…
In patients with acute myocardial infarction, immediate reperfusion of the occluded artery has significantly decreased early mortality rates and improved late clinical outcomes.1 Although current revascularization strategies using stent implantation…
Invasive coronary arteriography (CA) has been the standard method for imaging coronary lesions since its beginnings in 1958. Multidetector cardiac computerized tomography (MDCT) has undergone rapid developments over the last decade and now provides a…
Among percutaneous coronary interventional procedures, the treatment of bifurcation lesions with stents in both the main vessel (MV) and the side branch (SB) is one of the most complex. Several techniques have been suggested including T-, V-, Y-stent…
Dual left anterior descending coronary artery (LAD) (or dual anterior interventricular artery) distribution with either of the vessels originating from the left main coronary artery (LMCA) and the right aortic sinus of Valsalva is an extremely rare c…
