Clinical expertise
- Complex PCI — multi-vessel stenting, chronic total occlusions (CTO), rotablation, intravascular lithotripsy and orbital atherectomy
- Structural heart interventions — TAVI/TAVR, MitraClip and percutaneous valve repair & replacement
- Device closure of ASD, VSD and PDA
- Cardiac rhythm management — temporary & permanent pacemakers, CRT/CRT-D and ICD
- Intravascular imaging (IVUS, OCT) and physiology (FFR, RFR, iFR, DFR, QFR) — sometimes avoiding an unnecessary stent
- Radial & femoral angiography and angioplasty, balloon mitral valvotomy and peripheral intervention

Explain first, treat second
Every patient and family deserves to understand their heart condition in plain language before any decision is made.
Only the procedure you need
Pressure-wire physiology and intravascular imaging guide decisions, so stents are placed only when they truly help.
Minimally invasive whenever possible
Wrist-access angioplasty and catheter-based valve therapies mean less pain, fewer complications and a quicker return home.
Care that continues
Prevention, medication review and follow-up visits are part of treatment — not an afterthought.
