Angioplasty is a minimally invasive surgical procedure used to open up narrowed or blocked arteries or veins around the heart. It is also known as percutaneous coronary intervention or PCI. During this procedure, a deflated balloon attached to a tube is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. It is generally performed after an episode of chest pain or a heart attack. Having an angioplasty within the first few hours after a heart attack can reduce the risk of complications. This book contains some path-breaking studies in the field of clinical cardiology. It is a valuable compilation of topics, ranging from the basic to the most complex advancements in the field of angioplasty. This book aims to serve as a resource guide for students and experts alike and contribute to the growth of clinical cardiology.
