Summary of the 9th Annual Conferenceof the Japanese Society for Rotary

Blood Pumps

The 9th Annual Conference of the Japanese So-ciety for Rotary Blood Pumps was held at BunkyoCivic Hall in Tokyo, April 6th, 2001 with Prof. S.Takatani of Tokyo Medical and Dental Universityresiding as Congress President. Approximately 150people attended the Conference.

The scientific program was comprised of a specialinvited lecture, a symposium, a special educationallecture, four general sessions, and a panel discussion.A total of 28 papers were presented. The specialinvited lecture was delivered by Mr. Christoph Nix achief researcher of Impella Inc., Aachen, Germany,and the title was “Control Strategies for the ImpellaMicroaxial Blood Pump Based on the First ClinicalExperience.” The Impella Microaxial Blood Pump isa catheterlike intracardiac ventricular assist device(VAD). Mr. Nix emphasized the control aspect ofthe pump based on the built-in differential pressuresensor. In the symposium, entitled “What ShouldWe do about Monitoring and Control of the RotaryBlood Pumps”?, seven papers were presented to ex-plore monitoring and control issues related to therotary blood pumps. Prof. Teruaki Akamatsu of Set-sunan University, an inventor of the Terumo-Akamatsu magnetically suspended centrifugalpump, gave the special educational lecture. He pre-sented the very basics of the Axial, Centrifugal, andUndulation Pumps. General sessions were dividedinto four subsessions, “Basic Researches for Con-tinuous Flow Pumps,” “Development of RotaryBlood Pumps,” and “Pathophysiology of the Circu-latory Assistance with Continuous Flow BloodPumps (I) and (II).” The panel discussion focused onthe current status and the future of the clinical ap-plication of rotary blood pumps. Five speakers pre-sented the current status of rotary blood pumps forclinical application, such as an implantable LVAD,for long-term use in extracorporeal membrane oxy-

genation (ECMO), and for a new heart-lung assistdevice.

In the closing ceremony, Prof. Hikaru Matsuda ofOsaka University, the next Congress President, ex-tended an invitation to all the participants to thenext year Congress site of Rihga-Royal Hotel Osaka,August 27–30, 2002. He also hosts the 10th Congressof the International Society for Rotary Blood Pumpsduring the same time.

After the conference, a reception was held at theSky Hall located on the 26th floor of Bunkyo CivicHall. After the party was opened by Congress Presi-dent Prof. Takatani, Prof. Nitta of Tohoku Univer-sity, the immediate past president of the JapaneseSociety for Artificial Ograns gave a toast to the suc-cess of the meeting, and then the participants culti-vated their friendships and exchanged remarks allwith fantastic night view of Tokyo and excellentfood. The party ended after the closing address givenby Prof. Tsuchiya of Waseda University.

The program that follows provides an explorationof the progress in rotary blood pump research inJapan.
