She suffered a heart attack followed by recurrent episodes of irregular heartbeats

Doctors at Kauvery Hospital here performed three successive procedures to save the life of a 55-year-old woman who suffered a cardiac attack and a ventricular tachycardia (VT) storm (life threatening recurrent episodes of irregular heartbeats in a short span of time).

Addressing the media here on Tuesday, the doctors said they first performed a coronary angioplasty to place a stent and open the blocked artery that caused the heart attack, followed by a radio frequency (RF) ablation procedure to treat the irregular heart rhythm. The woman subsequently received a percutaneous defibrillator (a kind of pacemaker) implant as a precaution against future episodes of irregular heartbeats.

The doctors said Radha Balaji, who worked as a school teacher, had to undergo external defibrillation 14 times within a span of three to four days to control the VT storm until the RF ablation procedure was performed to permanently address it. “Not many people can handle multiple defibrillation procedures in such a short span. Moreover, these were mostly done when she was conscious. This shows her resolve, which helped immensely in her recovery,” said C.Sundar, senior consultant interventional cardiologist.

Ms.Balaji was brought to the hospital with low blood pressure and heart rate after she suffered a heart attack. Even while the angioplasty to place a stent was being performed, she had a few episodes of irregular heart-beats.

“Many patients do face a few episodes of arrhythmia (irregular heart rhythm) soon after a heart attack. However, it stops within 24 to 48 hours. Her case was, however, quite rare, as these life-threatening episodes did not stop and could not be controlled with medications,” Dr.Sundar said.

Further diagnosis and her medical history revealed that she had arrhythmia since a young age, but it did not require medical attention as many could have the condition without it ever becoming harmful, the doctors said.

Deep Chandh Raja, senior consultant cardiologist and clinical lead, cardiac electro-physiology, said a decision was made to perform RF ablation, a minimally invasive procedure to identify and destry the heart tissues that were causing the irregular rhythms.

“The procedure does not even need the patient to be anaesthetized. It is done with the help of a 3D imaging and navigation system that helps in identifying the tissues emanating the irregular electric signals. These tissues are then destroyed through a controlled heat burn. The entire procedure took about six hours,” Dr. Raja said.

Defibrillator installed

As she was prone to future episodes of arrhythmia, caused by tissues in the other parts of the heart, another procedure was done a few days later to implant a percutaneous defibrillator, he added.

Congratulating the doctors and the patient, AravindanSelvaraj, the hospital’s co-founder and executive director, attributed the successful treatment to the infrastructure available in the hospital and the doctors who worked as a team, particularly the internationally trained cardiac electrophysiologists.

He also launched a Kauvery Heart Rhythm Services wing at the hospital on Tuesday to focus specifically on heart rhythm related ailments.

A release from the hospital said the youngster met with a road accident three years ago, which resulted in an injury to the brachial plexus, a network of nerves responsible for carrying signals from the spinal cord to the shoulders and arms. G. Balamurali , consultant spine and neurosurgeon at the hospital, said when a person suffered damages to the brachial plexus, it would cause extreme pain and weakness of the limbs. “The pain experienced is so severe that some patients want their limbs removed,” he said. Surgical procedures such as nerve transfer, muscle transfer or tendon transfer and management of pain with medications were often not very effective, he said. The doctors at Kauvery Hospital, ther...

55-year-old man undergoes aortic valve replacement

-
Source: The Hindu , Chennai edition,  FRIDAY JULY 22, 2022   A 55-year-old man, who had underdeveloped limbs and was born with a single kidney, underwent an aortic valve replacement surgery at MadrasMedical Mission (MMM) . Doctors decided against Transcatheter Aortic ValveImplantation (TAVI) considering the risks involved due to his multiple co-morbidities and opted for surgical replacement with a tissue valve. The patient has deformities in his left upper and lower limbs due to a condition called phocomelia , where the limbs are underdeveloped. This deformity was the side effect of the drug Thalidomide given for morning sickness during pregnancy in the 1950s and 1960s. He was born with a single kidney and has had episodes of pancreatitis for which stents were placed, a press release said. He was diagnosed with a shriveled aortic valve and was having breathlessness. “We saw him in April this year. He had severe aortic stenosis. Traditionally, an aortic valve replacement s...
