Conclusions

An increased CFV in the proximal LCA was associated with cardiac death, incremental to the clinical and basic echocardiographic parameters.

All three coronary arteries could be visualised with TDE and CFVR could be assessed. The left anterior descending (LAD) coronary artery has been the most commonly interrogated, followed by the posterior descending artery (PDA). Technical feasibility to investigate LAD is high with more than 90 % in experienced hands and reaches nearly 100 % with the use of intravenous contrast agents. The feasibility of CFVR assessment in PDA is lower – in the range between  and 86 %. Left circumflex coronary artery (LCx) is most challenging of the three due to the particular anatomy of the artery and the poor resolution of the lateral wall.

Por que poucos ecocardiografistas realizam a analise?

.

O exame exige um acerto do aparelho que não acompanha as máquinas ou são inapropriados para o uso.

Mas é mais fácil do que parece.
