13. DEVICE DESCRIPTION
The PLATINIUM 4LV CRT-D 1744 ICD device and programming system. The programming
system includes the Sorin dedicated programmer with the SMARTVIEW programming
software connected to a CPR3 programming head. The programming system is configured
and furnished by Sorin.
The PLATINIUM 4LV CRT-D 1744 can serve as a defibrillation electrode (active housing) with
a total surface area of 62.4 cm².
The PLATINIUM 4LV CRT-D 1744 is designed to recognize and treat slow or fast VT and
VF by continuously monitoring atrial and ventricular activity to identify persistent ventricular
arrhythmias and to deliver appropriate therapies. PLATINIUM 4LV CRT-D 1744 features
the PARAD/PARAD+ algorithm, which is specifically designed to differentiate ventricular
tachycardias from fast rhythms of supraventricular origin. PARAD/PARAD+ continuously
monitors R-R interval stability, searches for long cycles, assesses the degree of P-R
association, evaluates sudden onset and determines the chamber of arrhythmia acceleration.
In addition to the advanced detection scheme, PLATINIUM 4LV CRT-D 1744 offers
programmable single, dual or triple-chamber pacing therapy (DDD, DDI, VVI or SafeR
(AAI <> DDD) modes) with or without rate-responsive capabilities (DDDR, DDIR, VVIR,
DDD/DDIR and SafeR-R (AAIR <> DDDR) modes) using an acceleration sensor. An
automatic AV delay algorithm as well as a mode switching function are available.
PLATINIUM 4LV CRT-D 1744 enables an adjustment of the interventricular delay, and
provides the possibility of adapting pacing to each ventricle. The ICD is intended to
resynchronize uncoordinated contraction of the heart by simultaneously or sequentially
pacing both ventricles.
PLATINIUM 4LV CRT-D 1744 features simultaneous multipoint left ventricular pacing allowing
LV pacing on 2 differents vectors at the same time.
PLATINIUM 4LV CRT-D 1744 offers tiered therapy. Therapies can be programmed
independently in each zone:
― in the Slow VT and VT zones: two ATP programs, up to two shocks with programmable
energy and up to four shocks with maximum energy can be programmed;
― in the VF zone: one ATP program, up to two shocks with programmable energy and up
to four shocks with maximum energy can be programmed.
The ATP can be applied in RV, LV or RV and LV pacing with a VV delay equal to 0 ms. ATP
pacing configuration is independent of ventricular pacing configuration.
When the rhythm changes from one zone to another, the device delivers the therapy
programmed in this zone, starting with the same or more aggressive program for the zone.
The ATP program in the VF zone will only be applied if the VT coupling interval is longer than
the programmed fast VT cycle length.
The PLATINIUM 4LV CRT-D 1744 offers biphasic shocks with a maximum stored energy
of 42 J. The shock configuration (electrodes used to apply the shock) can be chosen by
programming one of the following combinations: can and one coil, can and two coils, two coils
only.
Other features are as follows:
― Automatic ventricular sensitivity control
― Non-committed shocks
