Optimising Stent Deployment in Contemporary Practice: The Role of Intracoronary Imaging and Non-compliant Balloons

In 1995, stent implantation became the second revolution in interventional cardiology when Colombo et al. demonstrated that intravascular ultrasound (IVUS)-guided post-dilatation of stents to achieve optimal expansion and larger lumens led to reduced restenosis and stent thrombosis (ST).1 This ‘bigger is better’ hypothesis became the technical cornerstone of all stent implantation in the bare metal stent (BMS) era.

Cardiac Effects of Lightning Strikes

Lightning strikes between clouds and ground objects occur when the difference in electrical potential between the two is greater than 30,000 Volts, as thus they are able to exceed the atmospheric electrical resistance, generating currents that vary from 30,000 to 100,000 Amperes, and lasting between 0.1–0.001 seconds. As per data from the Lightning Imaging Sensor (LIS)-equipped satellite developed by the National Aerospace Agency (NASA), globally it is estimated that 44 flashes occur per second, with 1.4 billion flashes occurring in a year.1,2
