Background And Objectives: Use of Pulmonary Artery Catheter (PAC) is still a debatable issue, mainly due to questions raised about its security and efficacy. This study reproduced in a sample of Brazilian physicians, another one conducted amidst American doctors, in which was pointed out the heterogeneity of clinical decisions guided by data obtained from PAC.
Methods: During the Brazilian Congress of Intensive Care Medicine (Curitiba 2004), doctors were asked to answer a survey form with three vignettes. Each of them contained PAC data and one half of the surveys contained echocardiographic information. Every doctor was asked to select one of six interventions for each vignette. A homogeneous answer was considered when it was selected by at least 80% of the respondents.
Results: Two hundred and thirty seven doctors answered the questionnaires. They selected completely different therapeutic interventions in all three vignettes and none of the interventions achieved more than 80% agreement. Variability persisted with the choices guided by echocardiography.
Conclusions: As in the original study, we observed total heterogeneity of therapeutic interventions guided by CAP and echocardiography. These results could be caused by lack of knowledge about basic pathophysiologic concepts and maybe we had to improve its teaching at the medical school benches.

Background: Inadequate pulmonary blood flow in tetralogy of Fallot (TOF) can lead to the development of major aortopulmonary collateral arteries (MAPCA), which interferes with surgical repair. The present study evaluated the features of MAPCAs among patients with TOF and their treatment approaches. Besides, perioperative parameters and mortality rates of our TOF patients with and without MAPCA were compared.

Unlabelled: Scarring of the left atrial (LA) wall from atrial ablation (AF) leads to the development of stiff LA syndrome. Multiple ablation treatments have been considered to be associated with the development of LA calcification (LAC). We report a case of wild-type transthyretin cardiac amyloidosis (CA) who presented with worsening heart failure due to stiff LA syndrome despite the condition after initial ablation for AF.

Objectives: Postoperative pulmonary complications (POPC) are common after cardiac surgeries such as coronary artery bypass grafting (CABG) and are influenced by factors including anesthesia and surgical trauma. Inspiratory muscle training (IMT) with visual biofeedback may mitigate these complications. This study investigates the impact of threshold loading inspiratory muscle training (TL-IMT) combined with respiratory biofeedback on the dynamic strength of inspiratory muscles (S-index) in patients undergoing CABG surgery during their hospitalization phase.
