A life-saving device in singapore help end-stage heart failure patients stay fit for a transplant until healthy organ is available

Left Ventricular Assiste Device (LVAD) in singapore help end-stage heart failure patients stay fit for a transplant until healthy organ is available.
It is an implanted mechanical-pump that can mean the difference between life and death for a person whose heart is too weak to effectively pump on its own.
“When there’s a failure in the heart’s left ventricular chamber, the device aims to assist its main function to pump the blood through out the body without any obstruction” said Dr. Lim Chong Hee, a cardiothoracic surgeon at mount elizabeth hospitals in singapore.
restricted supply of oxygenated-blood flow to the body from the heart due to left ventricular failure increase the risks of damaging other organs as well, explained Dr. Lim.
Eventually, this condition may lead to total heart failure or death.

Multple uses of LVAD
An LVAD can be used either as temporary or a permanent solution to sustain the cardiac muscles. Some patients may need it until they fully recover or a heart is available for transplant, while others have to keep it for life.
“The LVAD briefly restores the heart function,which gives time for the body to reverse any organ damages, allowing the patient to go for a transplant in a better shape” explained Dr. Lim.
He also recommended implanting LVAD transitorily to recover from various treatable cardiac conditions, such as viral infections.
“While the patient is undergoing therapy, the LVAD will assist the heart function for a period of time until it significantly improves & is able to effectively do its job, then the LVAD pump can be removed,” he said.
In some cases, terminally ill patients who are ineligible for a heart transplant can permanently use an LVAD, which improves their survival odds.
Some studies have revealed that using a permanent LVAD device doubled the one- year survival rate of the patients with end-stage heart failure if compared with drug treatments alone.
On top of that, LVADs can be implanted in young patients as well.
For example, one of Dr. Lim’s youngest patients was an 11-year-old boy who flew in from malaysia on the verge of losing his life from heart failure. His chances of recovery were very slim until Dr. Lim was able to implant an LVAD. After weeks, he recovered & was able to return home.
However, some patients are too young to receive an LVAD because of their limited chest size, so the device has to be implanted externally, forcing patients to be hospitalised until the pump can be removed.

How the procedure works
The device is attached to left ventricular chamber in order to pump blood to the heart’s main artery known as aorta – through an open heart surgery.
This device will have a small wire that passes through the abdominal wall & is attached to an external computer controller, a batter & another reserve pack.
Dr. Lim explained that the controller provides energy to the device through the wire & is used to maintain the pumping speed in the heart. It also records data to help monitor the device’s behaviour.
Patients are required to wear these external units at all times, sometimes on a belt or harness, outside the body. the bayyery has to be recharged everyday.
“Unfortunately, technology has not advanced yet to the points where all the units of an LVAD can be implanted inside the body,” acknowledged Dr. Lim.

Post-op recovery
A patient’s recovery prospect depends on the individual’s overall health conditions before entring the operating theatre, according to Dr. Lim.
“LVAD mainly protects the heart function, so patients with other health issues like kidney or liver failure face an increased risk of complications & a longer recovery time,” he said.
Most patients are required to stay in the hospital for a minimum of two weeks to recover from the surgery, while being closely monitered for potential health risks associated with the organ failures.
Before leaving the hospital, patients & their caregivers are trained to recognise any circumstances that may pose a concern at home like low blood flow or any signs of infections. Also, both caregivers & patients must learn how to clean the device.
“As you get it, you can do normal activities like driving or light sports,” explained Dr. Lim.

Heart travels from Bengaluru to Kolkata hospital under four hours for successful transplant

/0 Comments/in /by

In a historic moment in the medical field in India, the heart of brain dead patient from Karnataka was successfully transplanted into a patient at a private hospital in Kolkata.

The donor, who was admitted to Sparsh Hospital in Bengaluru, was declared brain dead after he had an accident in March this year. His family members had expressed their willingness to donate his heart.

His heart was then transported 1,885 kilometres – 1,665 from Bengaluru airport to Kolkata airport, and 20 kilometres from the airport to Fortis Hospital at Anandapur in the eastern part of the city. Accordingly, authorities there contacted officials at Fortis Hospital for the transplant.

The beneficiary, 40-year-old Dilchand Singh from Jharkhand, had been suffering from a heart ailment for a few months.

The heart was brought in a special container, preserved with ice and cardioplegic solution. Doctors said that the heart needed to be transplanted within four hours of collecting it from the donor. The flight from Bengaluru to Kolkata took three hours.

At about 11.10 am the heart was taken out of the airport in Kolkata and then with the help of police authorities, it reached at the hospital in time.

Fortis officials had sought help from the state health department which in turn took the help of Bidhannagar Police Commissionerate had made arrangements for a green corridor for the ambulance carrying the heart and the doctors from the airport to Fortis Hospital. DCP (HQ) of Bidhannagar Police Commissionerate Amit Javalgi said that as soon as hospital authorities had told them about it, a pilot car escorted the ambulance and helped cover 18 kilometres in under 20 minutes.

The heart transplant was conducted under the supervision of Dr KR Balakrishnan, director, cardiac sciences and Dr Suresh Rao, chief cardiac anaesthetist from Fortis Malar Hospital in Chennai.

The team of doctors, who performed this surgery, included Dr Tapas Raychaudhury, director, cardio thoracic and vascular surgery, Dr KM Mandana, director, cardio thoracic and vascular surgery, and Dr Saikat Bandopadhyay, senior consultant, cardiac anesthesiologist and intensivist from Fortis Hospital, Anandpur.

Dr Raychaudhury said, “It is the first of its kind operation in eastern India. It is a history. Doctors from Chennai went to Bengaluru to collect the heart of a brain dead person. Then it is flown into Kolkata to be transplanted into a patient in Kolkata. It had never happened before,” he said.

The surgery began at about 12 noon and continued for three hours. After the surgery, doctors interacted with media persons and said they were happy about the operation which was a success but still the patient needed to be kept under supervision for 3-4 days.

“The patient is fine. Almost four hours have passed. He is stable, conscious. It was challenging because arranging the organ and transplanting here. Logisitics-wise it was challenging. We need to take care of the post operation heart surgery so that there is no infection,” said Dr Mandana

Dr Raychaudhury said that it was a pity that while in places like Bengaluru on an average two persons come ahead for organ donation every day in West Bengal there is a queue of 35,000 patients who are awaiting donors for a second lease of life.

Doctors said both the donor and the recipient being young, having more or less the same body weight and same blood group (A+), helped in the process.

Family members of Dilchand had registered his name for a transplant in 2016 and it could be done in not less than two years. Belonging to a below poverty level family, Dilchand was supported financially by the hospital.
