2. TRC Consequências da Dissincronia.
Preditor de piora da falência de VE, MS e mortalidade.
Enchimento ventricular sub ótimo
Piora da duração e gravidade da insuficiência mitral
Desvio paradoxal do SIV
Maior Volume Sistólico Final
Menor Débito cardíaco e fração de ejeção.
Maior mortalidade.
30 – 50% dos pacientes com IC avançada tem BRE - Preditor de maior
mortalidade.
3. TRC Benefícios TRC
Melhora caminhada 6 minutos
Melhora qualidade de vida
Aumenta DC sem piorar consumo de O2
Diminui internacoes por IC descompensada em torno de 30%
Melhora Classe Funcional NYHA
Melhora Fração de Ejeção.
Menor mortalidade em torno de de 25 – 35%.

4. TRC Benefícios TRC
Tempo da resposta à TRC:
A ressincronização ocorre imediatamente após implantação do MP
biventricular.
A reversão do remodelamento cardíaco é esperado em 6 meses.
MIRACLE trial: benefícios alcançados em 1 mês.
CARE-HF e COMPANION: benefícios alcançados em pelo menos 3 meses.

Notas do Editor
I think that every presentation regarding finance or investments has to be grounded in some type of metaphor. The right metaphor allows the audience to feel immediately comfortable with the presentation even though they may not have much prior knowledge on the subject matter. To me, sailing has always seemed to provide just the right terms to describe both the planning and patience required of a successful investor. Whether it be “charting the course” of an investment plan or having the patience required to navigate choppy markets, sailing and investing can make for a compelling presentation.

This slide illustrates more of a timeline or progression for completing major savings during the course of an investor’s lifetime. The slide serves to answer the age-old question, “Where am I now and where do I start?”.

This slide lays out the overall objective of the presentation; which is how to achieve or start working towards a “successful retirement”. It starts with a “written financial plan”, and moves clock-wise – all centered around the main goal. On this continuum, buttons can be added or removed, depending upon the financial professional giving the presentation.A successful retirement plan has many moving parts and each of them must serve a unique function in carrying you to retirement. Regardless of your situation, the journey to retirement is likely dotted with some storms and choppy seas along the way. Here, I have laid out what I believe to be the very basic principles necessary for any successful retirement plan.
