As Technology continues to evolve, it is reshaping the boundaries of what is possible in Interventional Cardiology.

Sharing a patients journey with us since 2022..This 73-yr old man with complex cardiac history (surgical mechanical mitral valve replacement in 2000 in Mumbai) underwent TAVI (for severe aortic stenosis) with us in 2022 and came back again with severe tricuspid regurgitation (leak) after 1 year. We implanted Tric valve (Bicaval valve- SVC and IVC valves) for his severe TR as it was not amenable for clipping and doing well since then. Recently he was admitted in his local hospital with collapse last week and diagnosed to have Tachy Brady syndrome (Irregular heart beat with long pauses). He was advised permanent pacemaker implantation.

He approached us and we decided to implant leadless pacemaker (Micra) directly into his right ventricle via leg artery (femoral access), which was successfully performed and got discharged the next day.

This is one of those rare patients with 5 prostheses in his cardiovascular system (one mitral valve, one TAVI valve, one valve each in SVC and IVC and now a MICRA leadless pacemaker) and I am pleased to say that 4 of those 5 devices are implanted by us.

Incredible enough, he lives many miles away in another state of India in a large city and every time he gets admitted there, he decide to come to us for his treatment after getting emergency care there. Humbled to have patients who have so much trust in us.

These technologies are boon to the modern society where it allow us to manage complex conditions in patients who were previously considered high risk or inoperable. These developments reduce procedural complications, shorten recovery times and improve overall outcomes.

Thanks for reading!

Little late post- Glad to share CHIP procedure with ELCA Laser angioplasty in 2 patients with high complexity and risk done last week..One of them had 100% blockage within an old stent done 12 yrs ago- successfully opened up and got good flow in the artery with Laser.
Another patient had critical stenosis of an old stent done 15 yrs ago with severe impairment of LV function (pumping capacity of 30%). laser angioplasty done with Intra Aortic Balloon pump (IABP) support and successfully placed new generation stent with good flow..Both patient got discharged within 48 hrs..
Glad to Host Dr Jaswindar Singh from Washington in our cath lab to discuss and guide us with these complex procedures using high resolution contrast laser..
