Waikato Hospital Pioneers New Procedure


Waikato Hospital Pioneers New Procedure


Waikato Hospital cardiologist Dr Sanjeevan Pasupati and cardiothoracic surgeon Mr Adam El Gamel have successfully pioneered a technique to treat one of the most prevalent heart valve diseases in the Western World.

Aortic regurgitation is a condition where the heart’s main outflow valve fails to close properly. This causes the blood that has already pumped out of the heart to leak back into the heart, such that it must be pumped out again with the next beat.

“The heart stretches to accommodate the extra blood that has to be pumped and becomes strained over time. Patients can become breathless and eventually develop heart failure,” said Mr El Gamel.

Traditionally, replacement of the aortic valve has required open heart surgery. However, 10-15 per cent of patients who need surgery for aortic regurgitation have other conditions that make it dangerous for them to undergo open heart surgery.

“The Edwards HELIO system technique involves a cardiologist working from the leg and a cardiac surgeon working simultaneously through a small incision on the chest.

“The pair work together to insert an anchoring device (dock) from the leg, to place it outside the patient’s aortic valve. A new valve is passed through the chest and the tip of the heart and placed inside the docking device. The whole apparatus is held in place by the old aortic valve, which is sandwiched between the docking device and the new valve. This procedure corrects the leak and acts as an alternative to major heart surgery,” said Dr Pasupati .

The treatment is an extension of another technique pioneered for New Zealand at Waikato Hospital in 2008 called transcatheter aortic valve implantation. This is used to treat a narrowed aortic valve (aortic stenosis), and involves a new valve being passed up from the leg, arm, or through a minimal incision on the chest.

Until now there was no similar procedure available for aortic regurgitation because anchoring the new valve was a challenge.

Dr Pasupati and Mr El Gamel, who are both involved in teaching the use of transcatheter implantation techniques around the world, worked with Edwards Life Sciences to develop the Edwards HELIO system programme.

Four patients have been treated using this approach in New Zealand. All four patients had a successful valve implantation with significant reduction in the leakage of the aortic valve.

“Remember these were very high risk patients. All four survived the perioperative period which is 30 days from the procedure,” said clinical unit El Gamel+19-02-2010_001best-resizedleader for internal medicine Dr Clyde Wade.
“During follow-up at 30 days, six and 12 months, all had a significant improvement in their symptoms.”

Four others have since received similar therapy in Vancouver on compassionate grounds in critically ill patients. The procedure remains experimental and will be further refined in Waikato and two new centres in Germany.

Dr Pasupati presented this pioneering work to 12,000 delegates at the EuroPCR conference in Paris yesterday (Thursday 23 May).

“For untreated severe aortic regurgitation, the 10 year mortality is 34 per cent and in this period 50 per cent would have developed significant heart failure. If they have significant symptoms and don’t undergo corrective surgery 50 per cent will be dead in one to two years, making this a lethal disease on its own merit,” he said.

“It’s a privilege to be a part of a groundbreaking technology.”
Dr Wade said this has been “the culmination of a 30 year journey”.
“We’ve gone from a cardiological backwater in Hamilton to now being internationally recognised. This wouldn’t have happened without the support of the Waikato Heart Trust, the National Heart Foundation of New Zealand and Waikato DHB,” he said.

The Waikato Heart Trust supported the initial transcatheter valve programme and the National Heart Foundation of New Zealand supported Dr Pasupati’s specialist training.
