Geometric Stent Design Mapping of Commercial Coronary Stent in Indonesia

This Coronary heart disease (CHD) is still a major health problem due to high morbidity and mortality. Coronary stenting is accepted as an interventional procedure to reduce morbidity and mortality due to CHD. One of the most common complications is restenosis which correlated with geometric properties of stent. Interventional cardiologists have the authority to choose the stent that is best for their patients. This study was to look at the geometric stent design mapping of existing commercial stent in Indonesia, from the perspective of an interventional cardiologist. Geometric stent design was the reason for choosing the stents when the proportion of use in teaching hospitals and nonteaching hospitals was the same and occupied the top 3 most used. There were 4 teaching hospitals and 12 non-teaching hospitals from different cities in Indonesia with the use of stent for a year by 11,813 coronary stents. Absorbable stents, bare metal stents (BMS), and drug eluting stents (DES) were 1.1%, 2.9% and 96%, respectively. The proportion of the number of stents used in teaching hospitals was 51% while that in non-teaching hospitals was 49%. Of the 11,813 stents, 49 commercial stent brand names were obtained with 41 types of geometric stent design produced by 21 manufacturers. Based on the collected data, there were 10 types of geometric stent design which were similar in prevalence between teaching hospitals and non-teaching hospitals, but the frequency of use was small. Meanwhile, the number of stents used in large numbers did not show the same prevalence between the two groups of hospitals. It can be concluded that geometric stent design is not yet the main reason for interventional cardiologists in determining the choice of coronary stents used for patients with coronary heart disease.
