Kantrowitz Team Implants 1st Permanent
PatifitirMtifiief+leart in Humarcat . Sinai

A team of surgeons led by Dr.
Adrian Kantrowitz, chairman of
the department of surgery at Sinai
Hospital, Wednesday morning suc-
cessfully implanted a permanent
partial mechanical heart in a
human p a t i e n t. The 10-hour
operation is the first procedure in-
volving the patch booster model
of a permanent auxiliary heart
pump.
Speaking before newsmen
Wednesday at Sinai, Dr. Julien
Priver, executive vice president
of the hospital, said that if "the
patient's vital signs continue to
improve, this will have been the
first successful implant of a per-
manent mechanical heart, either
whole or partial, in a human

being."
The patient, Haskell Shanks,
63, of Warren, had suffered from
congestive heart failure for the
past few years and his condi-
tion, according to doctors at
Sinai, had grown "progressively
worse the last few months."

When all standard medical and
surgical procedures had been ex-
hausted for treating intractable
failure of his left ventricle, the
heart's main pumping chamber,
it was decided to implant the patch

booster, the permanent heart assist

device.
Dr. Kantrowitz made the de-
cision Aug. 4, in consultation with
Dr. Melvyn Rubenfire, chief of
the cardiovascular section of the
department of medicine, and Dr.
Thomas Stock, cardiologist at Mt.
Carmel Hospital, after extensive
evaluation. Informed consent was
obtained from Shanks.
Dr. Priver said Shanks' condi-
tion is "satisfactory. The mechani-
cal heart is functioning well and
all vital signs are stable. The
patient is now in the heart.surgery
study area where he is wider in-
tensive care. He is conscious and
responding to commands."
Dr. Kantrowitz and members of
the Shanks family did not meet
the press at this time.
The patch booster, made of sili-
cdne rubber and Dacron, is not
meant to replace the patient's nat-
ural heart. It is an auxiliary pump
designed to take over permanently
about half the work of the heart's
main pumping chamber. It is air-
powered and can be used as long
as and when needed.

Should the patient's own heart
recover sufficiently to take over
on its own, the pumping action
can be stopped while the booster
remains in place acting only as
a graft or an added section of
the aorta.

The patch booster serves
three basic supporting functions:
It takes over a large portion
of the pumping load of the left
v en t r i c l e, the heart's main
pumping c h a m b e r, and thus
serves as an extra mechanical
heart; it increases the blood
flow through the coronary ar-
teries to the heart's own tissue,
thus increasing the amount of
energy available to the heart
to pump blood; and it increases
cardiac output, or blood flow
to the rest of the body.

NEW YORK (JTA)—The Zion-
ist Organization of America an-
nounced that Dr. Mikhail Zand,
Russian-born Jewish scholar who
withstood intensive Soviet har-
assment in his ultimately success-
ful attempt to emigrate to Israel,
will address its national conven-
tion in Pittsburgh.
Dr. Zand, who will be making
his first visit to the United States
will speak on the plight of Soviei
Jewry at the convention's opening
session on Sept. 2 and again at
a public affairs program Sept. 4.
The 44-year-old scholar in Orien-
tal languages had been a profes-
sor at the Institute for Eastern
Studies in Moscow until his par-
ticipation in a sit-in for Soviet
Jews last March resulted in his
arrest and imprisonment.
Dr. Zand has continued as a
forceful spokesman for Soviet

Jewry since coming to Israel. He

says Soviet Jews now seeking to
emigrate regard themselves as "an

inseparable part of the Jewish
people."
Speakers previously announced
for the 74th ZOA convention, in-
clude Israel Ambassador Itzhak
Rabin and Ehud Avriel, chairman
of the Zionist Actions Committee
of the World Zionist Organization.

The Man in the Trunk' Released
After 6 Years of 10-Year Sentence

TEL AVIV (JTA) — Mordecai
Louk, the "man in the trunk"
who was sentenced in 1965 to 10
years in prison for spying for
Egypt, was released Aug. 3 after
serving just over six years.
Louk was arrested in Rome in
November 1964, after being dis-•
covered, drugged and bound, in a
"diplomatic mail" trunk destined
for Cairo. The Moroccan-born Is-
raeli, then 29, returned to Israel
voluntarily, claiming he would feel
secure there, but a three-man dis-
trict court concluded that "he did
so for fear of his life" and ac-
tually "had no sense of responsi-
bility in an honest society."
It developed that the Egyptian
government had become dissatis-
fied with Louk's work and decided
to spirit him back in the trunk.
The defendant's plea was that he
had agreed to spy for Egypt only
to get out of jail, where, he said,
he had been kept illegally for 21
months as an escaped Israeli. He
