OCT IMAGING HELPS TO SEE HEART
BLOCKAGE MORE CLEARLY & STENT PLACEMENT MORE ACCURATELY: DR MANAN & DR
PRAVEEN

“Optical coherence tomography (OCT)
angiography is a promising diagnostic tool and has revolutionized the cardiac angiography
where cardiologists can see the clogged arteries clearly and with more accuracy.
It has in fact opened new horizons for
intravascular coronary imaging and has
become like a "third eye" of interventional cardiologist.” This was
stated by Dr Manan Anand , Head of Cardiology at Nayyar Hospital, Amritsar
while addressing a press conference at Hotel Hyatt here on Saturday. He said further that OCT is a light-based
catheter which acquires on an image inside the heart blood vessel. OCT is a
recently-developed, catheter-based Intravascular Imaging Technology that
provides micron-scale resolution. It is a laser light equivalent of ultrasound
imaging, measuring the intensity of backscattered infrared light rather than
sound waves, and translates these optical echoes into a high-resolution, two-dimensional
tomographic image, informed Dr Manan. OCT has the highest imaging resolution of
any currently-available technology, he said adding OCT imaging is also very
helpful in post angioplasty to see the positioning of the stent within the
vessel and clearance of blockage. Talking about the need of awareness on quality
stents among patients, Dr. Praveen Chandra, the Chairman of the Division
of Interventional Cardiology at Medanta – The Medicity said that in
2017 the government has brought prices of all types of stents equal. Now in
this scenario, it becomes very important for those going for insertion of stents
to open clogged heart arteries to be aware of quality of stents. In fact it
becomes duty of patient and his or her attendants to ask the surgeon to use
quality stent, maintained Dr Praveen. Stressing
upon the need to do Fractional Flow Reserve (FFR) , Dr Praveen said that FFR
should be done on each heart blockage patient so that it can be ascertained
that he or she requires stenting. FFR is used to determine if a cardiac patient
really needs a stent or bypass surgery or can be kept only on medicines
avoiding any procedure, he informed. Dr Praveen said that Dr Manan is already
doing complex cardiac interventional procedures at Nayyar Hospital,
Amritsar. Meanwhile a workshop of
complex heart procedures and OCT guided
angioplasty was also held in evening at hotel where both Dr Praveen and Dr
Manan discussed latest developments in cardiology treatment.
