Dr. Dash is among the rare cardiologists who has sustained active, high-volume practice across every major subspecialty — clinical, interventional, pediatric, electrophysiological, and vascular.
Dr. Dash has performed approximately 90,000 cardiac interventions over 35 years. His interventional work spans the full spectrum — from routine angioplasty to the highest-complexity left main interventions and structural heart procedures.
Percutaneous Transluminal Coronary Angioplasty including complex Left Main Intervention — among the highest-risk coronary procedures, requiring elite skill and judgment. Large-scale Primary PCI for acute STEMI patients, directly saving lives in time-critical emergencies.
One of India's most experienced practitioners of BMV — a minimally invasive procedure to widen a narrowed mitral valve using a balloon catheter. Particularly significant in India where rheumatic mitral stenosis remains prevalent. Success rates of 95%+ in suitable candidates, offering immediate symptom relief without open surgery.
Thoracic Endovascular Aortic Repair for Aortic Dissection — one of the most technically demanding procedures in cardiovascular medicine. TEVAR avoids open surgery, using a stent-graft deployed via catheter to seal the aortic tear and restore normal blood flow.
Dr. Dash's pediatric cardiac work — treating newborns, infants, and children — is among the most emotionally and technically demanding aspects of his practice, and one where his expertise has saved countless young lives.
Transcatheter device closure of ASD (Atrial Septal Defect), VSD (Ventricular Septal Defect), PDA (Patent Ductus Arteriosus) in newborns, infants, and children. Avoids open-heart surgery with minimal recovery time and excellent outcomes.
Balloon dilatation of congenital valvular stenosis (pulmonary, aortic) in children and adolescents. Dr. Dash's expertise in this area is documented through decades of practice at SSSIHMS — a leading pediatric cardiac centre.
Active screening and treatment of children under Odisha's District Early Intervention Centres (DEIC) and the national Rashtriya Bal Swasthya Karyakram. Ensures even the most economically disadvantaged children receive world-class cardiac care.
Mapping and diagnosis of complex arrhythmias through catheter-based electrophysiology — identifying the exact electrical circuits causing abnormal heart rhythms with precision before ablation.
Catheter-based thermal ablation to permanently eliminate arrhythmia pathways — treating SVT, atrial flutter, atrial fibrillation, and accessory pathway syndromes without long-term medication dependency.
Single, dual, and CRT pacemaker implantation and explantation. ICD (Implantable Cardioverter-Defibrillator) and CRT-D (Cardiac Resynchronization Therapy-Defibrillator) implantation for heart failure and sudden death prevention.
Carotid artery stenting for stroke prevention and limb artery stenting for peripheral arterial disease — minimally invasive alternatives to open vascular surgery with faster recovery.
Thoracic Endovascular Aortic Repair — used to treat life-threatening aortic dissection and aneurysm. A stent-graft is deployed via the femoral artery to seal and stabilise the aorta without open chest surgery.
Cardiac screening and treatment camps across West Bengal, Sikkim, Rajasthan, Madhya Pradesh, and multiple districts of Odisha — bringing specialist vascular and cardiac care to populations with no access to tertiary hospitals.
