The Board of Control for Cricket in India (BCCI) president Jagmohan Dalmiya underwent a "coronary angiography" after he was hospitalised in Kolkata on Thursday night, following a reported cardiac arrest.

The 75-year-old Cricket Association of Bengal (CAB) president was rushed to the BM Birla Heart Research Institute in the city at night after he complained of chest pains. Dalmiya was accompanied by his son Abhishek Dalmiya.

Former Indian cricket captain and CAB joint secretary Sourav Ganguly, along with Arup Biswas, minister-in-charge of sports (West Bengal) and CAB treasurer Biswaroop Dey also rushed to the private hospital.

"He [Jagmohan Dalmiya] complained of severe chest pain and now has been put in the Intensive Care Unit, doctors are constantly monitoring his condition. He was brought in around 9 pm today (Thursday)," a hospital spokesperson had told IANS.

It is believed that a blockage has been found in his heart, and according to a senior CAB official, Dalmiya is due to undergo a heart surgery.

However, the latest medical bulletin from the BM Birla Heart Research Institute did not say anything about a surgery. "Multiple lesions were observed with total occlusion of the left anterior descending coronary artery," the bulletin said.

The doctors also said that Dalmiya is "being closely monitored in the coronary critical care unit".

The coronary angiography is a procedure that uses special dyes and x-rays to see how blood flows through the arteries in the heart.

Dalmiya took charge of office as the BCCI president only in March this year, but due to health issues, he was unable to take part in the activities of the BCCI on a day-to-day basis. BCCI secretary Anurag Thakur filled in for him during all the meetings that took place this year.
