Real world single center experience with saphenous vein grafts interventions: should filters be filtered out?

Background: Percutaneous coronary intervention (PCI) of saphenous vein grafts (SVG) can be challenging due to no reflow phenomenon from distal embolization of debris and microvascular vasoconstriction, resulting in myocardial injury post-procedure. Guidelines promote the use of distal embolic protection devices (EPD) to protect the distal arterial bed during SVG PCI. However, this approach has shown less-than-optimal results in many studies.

Dual coronary - cameral fistula "double the trouble".

A patient presenting with worsening dyspnea and left-sided chest pain underwent heart catheterization, found to have a rare connection between the right and left coronary arteries draining into the left ventricle, consistent with dual coronary-cameral fistula.
