Unless a patient is brought to the cathlab directly from
admission, we advocate upfront use of GPIIb/IIIa in high risk
ACS patients. |
GPIIb/IIIa in UA/NSTEMI: upfront or in cathlab? | Upfront, because the results of several trials with these
drugs show a trend for best results when GPIIB/IIIa
antagonists are started earlier. According to these
results, GPIIB/IIIa should be started before the patient
reaches the cathlab. The results are not the same with
different drugs, so the choice of the drug is also important. |
One option. The data are very strong but of course we do not
know how Bivalirudin would compare to heparin only, or
against a reduced dose of a low molecular weight heparin |
Horizons-AMI: bilavirudin for primary PCI in the elderly? | Horizons-AMI showed very favourable results to the
Bivalirudin arm in almost all the endpoints and these
results were sustained during the follow-up. So I think
this is a favourable approach regarding the patient
population evaluated in this trial and should bring up
changes in clinical practice. |
No dogmas! And good judgement and patient selection is
essential for our practice.
However, in the majority of cases I would follow the "keep it
simple" principle and try to avoid a two stent strategy. |
Coronary bifurcation lesion: a dogma of keep it as simple as possible or good judgement on right selection of patients ? | I think that is best to keep it as simple as possible but
also not to use this rule as a dogma. There is also a
place for good selection and planning before intervention
in some patients or anatomic subsets. There are
situations that compel us to use different devices and
more than one stent and thus, good judgement is
essential. |
Very difficult problem indeed. We put a lot of effort into trying
to identify patients with low gradients that will benefit
from AVR or TAVI. Often the crucial investigation is a dobutamine
stress echo that documents contractile reserve and a
low aortic valve area with stress. |
How to exactly assess "low flow" aortic stenosis ? | There are several ways to assess “low flow” aortic stenosis
(AS). This evaluation should rely on complementary techniques
to assess valve area and transvalvular gradients and
left ventricular function. Probably one way is to use stress-
Echo with Dobutamine or exercise. It is also possible to use
different evaluations in the cathlab including aortic valve
resistance that can be useful to distinguish moderate or
severe AS with low flow. |
Patient selection is of the utmost importance. If the patient
is expected to live with a good quality of life following successful
TAVI, then we would offer this treatment also in this
patient group. |
Should patients with late stage aortic stenosis be still candidates for transcatheter aortic valve implantation? | Yes. Transcatheter valve replacement is the alternative for
high risk, “end stage” patients considered not acceptable for
surgical valve replacement. This technique has already
proved to be effective and successful in these patients. We
know that the surgical mortality is higher in patients with
poor left ventricular function or co morbidities. In these
patients, |
