OBJECTIVE Several mechanisms are known to produce mechanical stress during and after cardiac surgery, e.g. aortic cross-clamping and pulmonary artery banding (PAB). However, little is known about the transcription of myocardial genes which are changed during mechanical overload. This study was performed to investigate growth factor mRNA expression after PAB in porcine hearts. METHODS The expe...

Optimal management of coarctation with ventricular septal defect is difficult. Should one treat the coarctation, the ventricular septal defect, or both? This dilemma was investigated by reviewing 39 successive patients, aged less than 4 months, undergoing coarctation repair without pulmonary artery banding. Twelve hospital deaths occurred. Ventricular septal defect size was graded "blind" accor...

unilateral pulmonary artery agenesis (upaa) is a rare congenital anomaly during the 4 th  week of gestational age. it is defined as an absence of pulmonary parenchyma and its supporting artery. a 9-year-old girl was admitted to our hospital because of chronic cough. chest examination showed a decrement in lung sound of right hemi-thorax with expiratory wheeze. chest radiography (cxr) revealed a...

INTRODUCTION Pulmonary artery (PA) banding is a procedure associated with high morbidity and mortality rates. It however can effectively palliate several forms of congenital heart lesions with increased pulmonary flow. Occasionally, to obtain an optimal degree of banding following operation, readjustment of the band is inevitable. We describe the technique of adjustable PA banding to prevent th...

In this study, Sandrio et al. [1] describe their experience with an intraluminal band placed in the main pulmonary artery (PA) in 32 patients over an 8-year period, and advocate its use as optimal palliation for children requiring control of excessive pulmonary artery flow. The technique in itself is not new; Piluiko et al. [2] and Locker et al. [3] both described an identical procedure to the ...

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

Experience with patients undergoing pulmonary artery banding for control of substantial left-toright shunt associated with large ventricular septal defects has been reviewed in order to assess the effects of banding and the growth patterns of the subjects in relation to changes in cardiac loading. The series covers a periodfrom I960 through I968. All 22 infants studied had large ventricular sep...

Ten patients with hypoplastic left heart syndrome underwent cardiac catheterization to assess the effectiveness of palliative surgery designed to prepare them for a modified Fontan procedure. The objectives of palliation were to establish unobstructed systemic blood flow, normalize pulmonary blood flow and pressure, and relieve pulmonary venous obstruction. In the first four patients, systemic ...
