The study contains data about three major segments in the Percutaneous Coronary Interventional (PCI) market in the Association of Southeast Asian Nations (ASEAN) market, which are coronary stents, consumables, and embolic protection devices. Cardiac devices are conventionally developed to address major cardiac ailments such as heart blocks. They are reaching maturation. Most segments are getting commoditized and product differentiation between premium and low-end products is eroding. The study provides segment-wise data for traditional PCI devices across countries in the ASEAN. The study also provides a list of key market participants across each country. The variations across countries are largely due to market maturation and reimbursement trends.
