This is our second case using the Nipro Makoto NiRS-IVUS system which has updated AI features including automated vessel sizing and plaque burden calculations as well as lumenogram to ease the operation decision making process
And what a case it was!

This gentleman had episode of chest pain 1 week ago with gradual worsening dyspnea
Coronary angiogram showed severe 3VD with total occlusion RCA likely being the culprit vessel

After wiring the RCA, the NiRS-IVUS identified a vulnerable plaque with high lipid content at the proximal RCA
The case was complicated with no reflow phenomenon which reverted with adenosine as well as significant intramural hematoma which needed intervention with DES
After implanting 2 DES, we face another complication, perforation at distal PL which we successfully coiled! Glad that no pericardial effusion seen on ECHO

The patient is now stable and angina free in ICU

Makoto NiRS-IVUS is indeed a value added tool which is becoming a more complete package with the addition of such AI features
Thank you for introducing them to me!

Not many can say that their heart stopped but lived to tell the tale!

Ms Suky is apparently one of them!
Earlier this year, this 24 years young lady came to our emergency department complaining of chest pain 🏥
She visited a primary care clinic previously and was told to have an abnormal ECG
Indeed her ECG showed first degree heart block with RBBB
1 week prior to this, she had a bout of viral like illness after returning from a trip abroad
Her cardiac enzymes were also grossly elevated

A diagnosis of acute myocarditis was made which was later confirmed via a cardiac MRI
While in ICU she had bouts of ventricular standstill (heart stop)
One particular episode occurred while I was speaking to her explaining her condition
She suddenly had up-rolling of eyeballs, all limbs stiffen, lost consciousness and went into a fit
At that time the cardiac monitor showed no heart activity. Indeed she was having an episode of cardiac arrest
Immediate CPR was performed by the ICU team and we brought her immediately to the cath lab to insert a pacing wire
While the episode was indeed a near death one which was very scary for her, it was equally scary for me as her treating doctor! 😅

After initiating cardiac and anti-inflammatory medications, her heart gradually stabilise and she made complete recovery
A repeat MRI 2 months later showed no residual scarring and her ECG has return to normal! That’s great news for this young lady! 👍🏻

Yesterday I have discharged her from my follow up
I hope she have a long and fulfilling life ahead! God bless! 🎉

Heart conditions are varied and can affect young and old! Constant awareness of such situations is very much needed

This is Bobby
He is 42 years old and is from Jakarta, Indonesia

He has an interesting story
Last year he and a group of friends went to Penang for health screening where he was told to have an abnormal stress test
He was then advised to undergo coronary angiogram which he refused

In November, he was admitted to a hospital in Indonesia where he underwent a coronary angiogram which revealed severe narrowing of two major blood vessels of his heart
He was advised for immediate angioplasty which he again refused

The reason for refusing is at the beginning denial as well as wanting to look for an alternative without a permanent implant
Thus he and his insurance agent began looking for such option

By fate he consulted me in April this year where we discuss the option of resorbable scaffold

We successfully performed the angioplasty using Freesolve bio-resorbable scaffold
Freesolve is a magnesium base scaffold which is fully resorbable after 1 year thus leaving no permanent implant inside the coronary artery

As compared to a drug eluting stent which is implanted for majority of patient undergoing angioplasty, the drug on such implants eludes over a period of 1 year
After 1 year, it no longer has any drug properties and what’s left behind is a metallic scaffold which has no function
This permanent scaffold put patient at a background risk of 2% restenosis each year

From the Biomag studies, the Freesolve scaffold is fully resorbed after 1 year and we see the incidence of restenosis completely plateau after 18 months

In a suitable patient, Freesolve bio-resorbable scaffold can be an ideal solution especially in younger patients suffering from coronary artery disease

From Bobby’s story I learn a few things
Know your options! Do it right! And do it right the first time!

Ini Bobby
Dia berusia 42 tahun dan berasal dari Jakarta, Indonesia

Dia memiliki kisah yang menarik
Tahun lalu dia dan sekelompok teman pergi ke Penang untuk pemeriksaan kesehatan di mana dia diberitahu bahwa hasil tes stresnya abnormal
Kemudian dia disarankan untuk menjalani angiogram koroner yang dia tolak

Pada bulan November, dia dirawat di sebuah rumah sakit di Indonesia di mana dia menjalani angiogram koroner yang mengungkapkan penyempitan parah pada dua pembuluh darah utama jantungnya
Dia disarankan untuk segera menjalani angioplasty yang sekali lagi dia tolak

Alasan penolakannya adalah pada awalnya penyangkalan serta keinginan untuk mencari alternatif tanpa implan permanen
Oleh karena itu dia dan agen asuransinya mulai mencari pilihan tersebut

Secara kebetulan dia berkonsultasi dengan saya pada bulan April tahun ini di mana kami membahas pilihan stent yang dapat diserap

Kami berhasil melakukan angioplasty menggunakan stent bio-resorbable Freesolve
Freesolve adalah stent berbasis magnesium yang sepenuhnya dapat diserap setelah 1 tahun sehingga tidak meninggalkan implan permanen di dalam arteri koroner

Dibandingkan dengan stent yang melepaskan obat yang Jika implan dipasang pada sebagian besar pasien yang menjalani angioplasty, obat pada implan tersebut akan hilang setelah 1 tahun.
Setelah 1 tahun, implan tersebut tidak lagi memiliki sifat obat dan yang tersisa hanyalah kerangka logam yang tidak berfungsi.
Kerangka permanen ini menempatkan pasien pada risiko restenosis sebesar 2% setiap tahunnya.

Dari studi Biomag, kerangka Freesolve sepenuhnya diserap setelah 1 tahun dan kita melihat insiden restenosis benar-benar stabil setelah 18 bulan.

Pada pasien yang sesuai, kerangka bio-resorbable Freesolve dapat menjadi solusi ideal, terutama pada pasien yang lebih muda yang menderita penyakit arteri koroner.

Dari kisah Bobby, saya belajar beberapa hal:
Ketahui pilihan Anda! Lakukan dengan benar! Dan lakukan dengan benar sejak pertama kali!

Having high blood pressure that is difficult to control despite on medications?
Want to reduce dependence on bp lowering drugs?

Renal denervation may be an option for you

Today we perform this procedure for a gentleman with resistant hypertension despite on multiple medication
This is a minimally invasive procedure where we insert a catheter to the kidney artery where radio frequency energy is emitted disrupting the overactive nerves surrounding it

This procedure can help reduce overall blood pressure as well as reduce dependence on medications

It is safe with minimal complications and very quick recovery

This is Mr Jit Ghosh
He is a traveller from Calcutta, India

While visiting Batu Caves on 1st April 2026, he experience severe crushing chest pain at around 8am
Unaware of what is really happening, he continued with his tour to Genting Highlands
There his symptoms worsen so he seek medical help at a local General Practice
He was diagnosed with a massive heart attack (Acute Anterior Myocardial Infarction) and was quickly referred to our centre

He arrived at 4pm which is already 8 hours after the onset of chest pain
Our emergency team quickly stabilised him and provided critical blood thinning medication
He was then transferred to the cath lab where I perform primary angioplasty to the Left Anterior Descending artery
A stent was deployed to re-establish blood flow to his heart
From the moment he walk through the door till the procedure took only 28 minutes! Kudos to the team for efficiency

Post procedure his heart rhythm became unstable (ventricular tachycardia)
He was given medication and electrical shock a total of 4 times

While nursing in ICU, his heart suddenly stopped (ventricular standstill)
The ICU team quickly perform CPR and code blue was activated
We brought him back to the cathlab where a temporary pacing wire was inserted and intra-aortic balloon pump to support his cardiac function

Subsequently, slowly but steadily he was wean off life support medications and is now able to walk and breathe unaided

He is due to fly back to India today to be with his family

To save a life truly takes a team effort
From the emergency department to the cath lab and ICU team, all play a crucial role in Mr Jit survival
I will like to thank Dr Suana, our anaesthetist whom help me manage Mr Jit as well

LithiX! It works!
No cutting wires! No power source!
Just a balloon but it works!

I was asked to join a colleague at my centre to treat this long diffuse calcified LAD

With the help of guide extension we did sequential balloon dilation but was unable to achieve full balloon expansion with NSE Alpha despite going high pressure up to 26atm

We then switch to LithiX lithotripsy balloon which dilated the lesion fully at 5atm!

Completed the case with DES implantation

In Asia we are seeing an epidemic of diabetes!
Patients often comes with long diffuse coronary artery disease which are challenging to treat

Today with drug coated balloons, this technology offers a unique solution especially in distal small vessels
This allow us to treat such patients without using a stent, potential late lumen gain rather than late lumen loss while preserving the vessel for future option of bypass surgery

This 29 year old gentleman presented with heart failure
He has poorly controlled diabetes
The LAD is diffusely diseased

Here we took a hybrid approach by treating the proximal lesion with bioadaptor DynamX and the distal vessel with Restore Plus DCB
The introduction of 40mm length is ideal in this scenario
