We are the first in nation developing a successful technique for percutaneous closing of ascending aortic pseudoaneurysm emptying into the right atrium without a need of surgery.

In November 2010, Vichai Benjacholmas, MD, director of Cardiac Center at KCMH proudly announced a great success in medical innovation using catheter technique to treat ruptured aneurysm emptying into the right atrium in a 43-year-old Thai Male who is status post aortic valve replacement, and presented with severe heart failure, liver failure, and impending cardiogenic shock. Generally, the standard treatment of this aneurysmal rupture is open heart surgery. However, in this case, the surgical challenges occurred when the aneurysm was sitting just beneath the sternum where the surgical blade takes place.

Additionally, with liver failure and severe heart failure, the surgical mortality and morbidity are tremendously high. With the best intensive attempt to save the patient’s life, Pornthep Lertsapcharoen, MD , Smonporn Boonyaratavej, MD, and Suphot Srimahachota applied a device closure for congenital heart defect to close the ruptured aneurysm in this patient. The device was developed initially in animal model and made in Thailand which costs much less than imported one. The results of closure are similar between Thailand-made and imported device.  Luckily, the neck of the aneurysm is narrow and suitable for device closure.


The 3-D transesophageal echocardiogram was performed by Dr. Boonyaratavej to assess for device selection. With an exceptional catheter skill, Dr.Lertsapcharoen and Srimahachota placed the catheter in the neck of the aneurysm through the aorta via the femoral artery and successfully deployed a device at the aneurysmal neck. The aneurysm was collapsed once the device was plugged in . The patient was dramatically improved with an uneventful recovery of heart and liver function.
