Interventional Cardiology came into being during early 1950s. Interventional cardiology has seen substantial advances in last couple of decades, be it World or India. Interventional Cardiology started as brachial artery coronary cine angiography. The initial decade after the advent of interventional cardiology was only dedicated to its diagnostic use; it was in late seventies when the horizon of interventional cardiology broadened. In 1977 Andreas Gruentzig introduced the cardiologist to therapy, with percutaneous transluminal coronary angioplasty (PTCA). This initially slender spectrum of balloon dilatation has broadened into the large spectrum of interventional cardiology, which now encompasses both diagnostic and therapeutic modalities for coronary artery disease. The main advantages of interventional cardiology are the avoidance of the pain, scars, and long postoperative recovery associated with surgery. The book is a comprehensive guide to understand the clinical application of Interventional Cardiology with special reference and experience in India. The authors have put together the most relevant facts about the disease for an easy comprehension and understanding of the same by practitioners and students across the specialty.
