Bandagem da artéria pulmonar: uma cirurgia simples? Uma análise crítica em um centro terciário Pulmonary artery banding: a simple procedure? A critical analysis at a tertiary center Abstract Objective: Although pulmonary artery banding (PAB) seems to be a technically simple procedure it presents several peculiarities and is related to a significant morbidity and mortality. The aim of this study is to analyze the experience of a tertiary hospital on the PAB by assessing and correlating many aspects related to the procedure.Methods: Between January 2000 and December 2008, 61 patients undergone PAB due to congenital heart disease with increased pulmonary blood flow at Messejana Heart Hospital were assessed as for mortality, complications, stay in mechanical ventilation and need for intensive care unit (ICU), use of vasoactive drugs, difficulties in the adjustment on the banding and reoperations. Some statistical analyzes were performed to compare the subgroups.Results: In 36.17% of the patients the intended pressoric adjustment was not achieved and in 6.5% it was necessary another surgery to readjust the banding. The mean time of mechanical ventilation was 14.1±49.6 days and ICU 14.16±10.92 days. In 82.6% of the patients vasoactives drugs were administrated for 10.3±12.79 days. Severe complications were noted in 49.15% of patients and cardiac insufficiency was the most common one with an incidence of 44%. The mortality rate was 8.2% and it was not influenced by weight or associated procedures with the PAB neither if univentricular or biventricular heart disease.Conclusion: The PAB can be performed with acceptable mortality rates compatible with the ones of the world literature. Nevertheless, the adjustment of the banding is difficult to be assessed during the surgery by making the This study was carried out at Dr.

“…Four study groups with seven young goats each (between 30 and 60 days of age) were used for induction of RV systolic overload using an experimental model of reversible PT banding [14][15][16]. Each group underwent twelve hours of systematic stimuli of RV systolic overload, followed by 12 hours of resting divided in training groups of 24 hours (Group 24, weight: 9.64 Kg ± 0.95 Kg), 48 hours (Group 48,weight: 9.64 Kg ± 0.95 Kg), 72 hours (Group 72, weight: 8.76 Kg ± 1.17 Kg) and 96 (Group 96, weight: 8.13 Kg ± 0.75 Kg).…”

Background: Chronic obstructive pulmonary disease (COPD) is one of most common cause of death. Pulmonary hypertension, one of the major and under diagnosed complications of COPD which have a great impact on outcome of COAD and associated with frequent exacerbations and bad prognosis. Echocardiography provides a rapid, noninvasive, portable, and accurate method to evaluate changes related to pulmonary hypertension in COAD.Objective Of Study: Study pulmonary artery systolic pressure and Tricuspid annular plane systolic excursion in patients with COAD by 2D ECHO Doppler and correlate them with COPD severity. Method:Cross sectional study was conducted on 50 COPD patients in Baghdad teaching hospital (age>40 year) from first of January to the end of June, 2017. First, the diagnosis of COPD was confirmed and evaluated for staging by history, clinical examination, and spirometery.All patients have undergone ECG and 2D echocardiography and systolic pulmonary artery pressure and Tricuspid Annular Plane Systolic Excursion (TAPSE) were calculated. Patients with other cardiac or respiratory problems (asthma, pulmonary TB, lung malignancy, connective tissue diseases, interstitial lung disease, and cardiac ischemia, left side heart failure) were excluded from this study.Results: Study of PASP by TR jet with the use of 2D ECHO on 50 patients with COPD showed that 20 patients had normal echo study , mild increase in PASP was found in 15 patients, moderate 11, and severe increase in 4 patients.Study of TAPSE by 2D ECHO showed that 35 patients had normal TAPSE values, while others 15 had abnormal values classified as mild, moderate, and severe: 3, 9, and 3, respectively.A significant associations between echo findings of increasing PASP and abnormal TAPSE, with decrease in FEV1, and oxygen saturation measured by pulse oximeter, duration since COPD was diagnosed and MRC dyspnea scale. Conclusion:High incidence of pulmonary hypertension with increasing severity of COAD. Echocardiography is useful and effective tool for detection of PHT secondary to COPD.
