Interventional cardiology is a specialization in cardiology. It is concerned with the treatment of structural heart diseases by catheterization. It typically involves the insertion of a sheath into the femoral artery, a peripheral artery or vein, and the cannulation of the heart using X-ray visualization. Some of the procedures in interventional cardiology are angioplasty, valvuloplasty, coronary thrombectomy, congenital heart defect correction, etc. The main advantages of interventional cardiology are the avoidance of a long post-operative recovery, pain and scars. The procedure of primary angioplasty, involving the deployment of stents and balloons, and the extraction of clots from occluded coronary arteries, is recommended for acute myocardial infarction. This book covers in detail some existing theories and innovative concepts revolving around interventional cardiology. Some of the diverse topics covered herein address the varied practices of interventional cardiology. It includes contributions of experts and scientists, which will provide innovative insights into this field.
