Electrocardiogram (ECG)
A quick, painless 5-minute test that records your heart's electrical activity to detect rhythm problems, heart attacks and strain on the heart.
Learn moreEchocardiogram (ECHO)
An ultrasound scan of the heart that shows its pumping strength, valves and chambers — safe, painless and radiation-free.
Learn moreTreadmill Test (TMT / Stress Test)
An exercise ECG that shows how your heart copes with effort — helpful to detect blocked arteries that cause symptoms only on exertion.
Learn moreCoronary Angiography (CAG)
The gold-standard test to see blockages in the heart arteries, usually done through the wrist in about 15–20 minutes.
Learn more
Angioplasty & Complex Stenting (PTCA)
Opening blocked heart arteries with a balloon and drug-eluting stent — including multi-vessel disease, left main and chronic total occlusions (CTO).
Learn more
TAVR / TAVI — Transcatheter Aortic Valve Replacement
Replacing a narrowed aortic valve through a small puncture in the groin — without opening the chest. Ideal for elderly and high-risk patients.
Learn morePacemaker, CRT & ICD Implantation
Small implanted devices that correct a slow heartbeat, improve a weak heart's pumping and protect against dangerous rhythms — with a dedicated device follow-up clinic.
Learn morePreventive Cardiology & Heart Check-ups

Our approach
Care that feels as good as it works
- 01
Explain first, treat second
Every patient and family deserves to understand their heart condition in plain language before any decision is made.
- 02
Only the procedure you need
Pressure-wire physiology and intravascular imaging guide decisions, so stents are placed only when they truly help.
- 03
Minimally invasive whenever possible
Wrist-access angioplasty and catheter-based valve therapies mean less pain, fewer complications and a quicker return home.
- 04
Care that continues
Prevention, medication review and follow-up visits are part of treatment — not an afterthought.
