Coronary artery disease (CAD) remains one of the leading causes of death worldwide. Over the decades, interventional cardiology has evolved dramatically—from balloon angioplasty to bare-metal stents, drug-eluting stents, and now, precision-guided interventions using advanced imaging tools. Among these advancements, drug-coated stents (DCS) combined with intravascular imaging (IVUS & OCT) have emerged as true game-changers. This […]

By Dr. Dhamodaran KSenior Interventional Cardiologist, Apollo Hospitals, Chennai Introduction Mitral regurgitation (MR) is one of the most common valvular heart diseases worldwide, and in its severe form, it can cause significant morbidity and mortality. The mitral valve, located between the left atrium and left ventricle, plays a crucial role in maintaining one-way blood flow […]

Percutaneous Coronary Intervention (PCI), commonly known as angioplasty with stenting, has dramatically evolved over the last two decades. While traditional angiography provides a two-dimensional view of coronary arteries, it has limitations in visualizing complex plaque structures and vessel morphology. This is where intravascular imaging techniques, such as Optical Coherence Tomography (OCT) and Intravascular Ultrasound (IVUS), […]

When it comes to coronary artery disease, coronary artery bypass grafting (CABG) is often a life-saving and life-enhancing procedure. However, one of the challenges that patients and cardiologists face after bypass surgery is the possibility of re-blockage, or what is sometimes called bypass failure. This can lead to symptoms returning and the need for further […]

Drug-coated balloons (DCBs) have revolutionized coronary percutaneous coronary intervention (PCI) since their introduction in 2006. As a cardiologist deeply involved in interventional procedures, I have witnessed firsthand the evolution of these devices and their expanding role in complex coronary artery disease management. This article delves into the nuances of DCB technology, focusing on the distinctions […]

Aortic stenosis is one of the most serious valve conditions that can affect the heart. Often underestimated in its early stages, it can silently progress to severe symptoms and life-threatening complications. Fortunately, patients in Chennai have access to one of the country’s most trusted names in interventional cardiology — Dr. Dhamodaran K, practicing at Apollo […]

When it comes to treating heart disease, precision is everything. And for Dr. Dhamodaran—one of the most respected interventional cardiologists in India—precision starts with clarity. That’s where IVUS steps in. Short for Intravascular Ultrasound, IVUS is not your typical heart scan. While traditional angiograms sketch the roadmap of your arteries, IVUS dives beneath the surface—right […]

RHD is a chronic heart condition resulting from damage to the heart valves caused by rheumatic fever—a complication of untreated or inadequately treated group A streptococcal (GAS) infections, such as strep throat or scarlet fever. The body’s immune response to these infections can lead to inflammation in the heart, joints, skin, or central nervous system. […]
