Polymer coating of the drug eluting stent reduces the expandability of the DES.<br \/>\n<strong>Binary restenosis after percutaneous intervention<\/strong><br \/>\nBinary restenosis is 50% or more of luminal narrowing at repeat angiogram.<br \/>\n<strong>Late loss of lumen<\/strong><br \/>\nMinimal luminal diameter at the end of the procedure minus the minimal luminal diameter at the repeat angiogram, generally at 6 months.<br \/>\n<strong>Instent restenosis<\/strong><br \/>\nInstent restenosis is often asymptomatic. One third of cases of in stent restenosis can present with acute coronary syndrome and was quoted as an indication for routine coronary angiography at 3 to 6 months after unprotected left main stenting.<br \/>\n<strong>Geographical miss<\/strong><br \/>\nGeographical miss is failure to cover whole of the diseased segment during stenting.<br \/>\n<strong>Black hole seen on IVUS in coronary restenosis<\/strong><br \/>\nBlack holes are sonolucent areas within areas of restenosis by intravascular ultrasound. Regions near the IVUS catheter and towards the adventitia are more echogenic while the area in between is sonolucent and are called black holes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Important terminologies in coronary angioplasty.<\/p>\n","protected":false},"author":1,"featured_media":37687,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"nf_dc_page":"","footnotes":""},"categories":[18],"tags":[],"class_list":["post-1336","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-angiography-and-interventions"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Coronary angioplasty - terminology: Short explanations<\/title>\n<meta name=\"description\" content=\"Coronary angioplasty - terminology: Important terminologies in coronary angioplasty like acute vessel closure, in stent restenosis.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/johnsonfrancis.org\/professional\/coronary-angioplasty-terminology\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Coronary angioplasty - terminology: Short explanations\" \/>\n<meta property=\"og:description\" content=\"Coronary angioplasty - terminology: Important terminologies in coronary angioplasty like acute vessel closure, in stent restenosis.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/johnsonfrancis.org\/professional\/coronary-angioplasty-terminology\/\" \/>\n<meta property=\"og:site_name\" content=\"All About Cardiovascular System and Disorders\" \/>\n<meta property=\"article:published_time\" content=\"2009-07-16T14:39:31+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2023-12-25T03:08:55+00:00\" \/>\n<meta name=\"author\" content=\"Johnson Francis\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Johnson Francis\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"1 minute\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"Article\",\"@id\":\"https:\\\/\\\/johnsonfrancis.org\\\/professional\\\/coronary-angioplasty-terminology\\\/#article\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/johnsonfrancis.org\\\/professional\\\/coronary-angioplasty-terminology\\\/\"},\"author\":{\"name\":\"Johnson Francis\",\"@id\":\"https:\\\/\\\/johnsonfrancis.org\\\/professional\\\/#\\\/schema\\\/person\\\/5441d907049b914770f4bd98fb57feec\"},\"headline\":\"Coronary angioplasty &#8211;
