Plaque morphology and distribution in patients with and without myocardial bridge - an intravascular ultrasound study.

Background: Myocardial bridging (MB) is a common congenital cardiovascular anomaly. There are reported associations of MB with different clinical presentations like effort angina, acute coronary syndromes (ACS) and sudden cardiac death. Acceleration of atherosclerosis in proximal vessel is reported in patients with MB, while bridged segments are reported to be free of atherosclerosis.

'Routine intravascular ultrasound evaluation and change in stenting strategy in primary percutaneous intervention (RIST PCI)'.

Background: Intravascular ultrasound (IVUS) provides better assessment of vessel size, lesion length and plaque characteristics. There is paucity of data regarding the impact of IVUS on stenting pattern during primary percutaneous intervention (PCI) for ST elevation myocardial infarction (STEMI).

Methods: We included patients with STEMI undergoing IVUS-guided primary PCI.
