Use of the pressure wire method for measuring pulmonary arterial pressures in patients with pulmonary atresia

Abstract: Measurement of pulmonary vascular pressures using the pressure wire in small patients with pulmonary atresia is safe and effective. It allows the acquisition of reliable pressure curves, even in the presence of small vessels, bending and tortuosity, without the risk usually associated with the use of conventional diagnostic catheters.

“…Use of this wire to measure pressures in circumstances other than in the determination of severity of coronary stenosis has been described, although the use in the pulmonary vasculature has been limited to pediatric patients to measure congenital pulmonary stenosisrelated pulmonary hypertension. (6,7) Use of this technique routinely is likely unnecessary given the safety of traditional methods, as well as the higher cost of the pressure wire compared to traditional Swan-Ganz catheters. However, there may be circumstances where the need for accurate and safe measurements of PA and right heart pressures are worth the incremental cost.…”

“…9 No presente trabalho, estendemos o conceito da praticalidade do método manométrico baseado no uso de pressure-wire para diversas aplicações em pacientes portadores de cardiopatias congênitas e adquiridas. As aplicações práticas decorrentes desse conceito são, portanto, expandidas a partir da utilização, em nosso laboratório de Hemodinâmica e Cardiologia Intervencio nista, para o contexto específico da atresia pulmonar, como descrito recentemente por Haddad et al, 10 ao de monstrar a factibilidade e a segurança da técnica em dez pacientes pediátricos.…”

“…Tais características são vantajosas para obtenção de curvas pressóricas em diferentes segmentos pulmonares nos pacientes com atresia pulmonar e fluxo pulmonar dependente do canal arterial ou de co laterais sistêmico-pulmonares, como demonstrado pelo mesmo grupo em outra publicação. 2 Essa informação é importante para o planejamento cirúrgico, já que áreas pulmonares com hipertensão grave podem coexistir com outras nas quais a pressão é normal. A aplica-ção, nos casos de estenoses das artérias pulmonares, especialmente as críticas ou subatréticas, também é útil para determinação da gravidade da lesão.…”
