Determining distal wire position during chronic total occlusion percutaneous coronary intervention can be challenging. We describe a novel technique that can help confirm distal true lumen wire position. A microcatheter is advanced distally over the wire and after removing the guidewire, it is connected to a manifold for pressure transduction: an arterial waveform is indicative of intra-luminal position.
