“…Techniques have been developed to deal with this problem, including balloon-dilatable band, absorbable staged expanding band, and extrathoracically adjustable band using a fluid-filled reservoir or a tourniquet system. [21][22][23][24][25][26][27][28][29] In general, these devices allow for adjustments of the banding but primarily within the first days after operation or with the requirement of procedures such as cardiac catheterization.…”

Proponents of a telemetrically adjustable pulmonary artery band (PAB) device have cited simplified postoperative management and shortened length of stay as advantages associated with that technology. This report concerns a recent experience with both conventional pulmonary artery banding (conv-PAB) and the telemetrically adjustable PAB FloWatch (FW-PAB). From January 2005 through December 2008, 19 consecutive infants underwent either conv-PAB (8 patients, mean age 3.5 months, mean weight 4.1 kg) or FW-PAB (11 patients, mean age 2.6 months, mean weight 3.1 kg). Indications for PAB were left ventricular retraining (1 patient in FW-PAB), palliation prior to biventricular repair (7 patients in conv-PAB and 10 in FW-PAB group), and staged univentricular repair (1 patient in conv-PAB). In-hospital mortality was 0%. In the FW-PAB group, 1 FloWatch device was removed because of hemodynamic compromise related to the bulk of the device. There were no major complications in the conv-PAB group and no differences between groups with respect to postoperative ventilation time or length of stay in the intensive care unit or in hospital. In the FW-PAB group, a mean of 3.1 ± 1.7 regulations per patient were undertaken. Of the regulations, 85% (29/34) were adjustments to tighten the device, and 15% (5/34) were to loosen it. During follow-up, 8 patients underwent intracardiac repair and pulmonary artery debanding: 4 in the conv-PAB group and 4 in the FW-PAB group. The course of patients in both groups after PAB were similar. Major differences in length of stay and resource utilization were not apparent.

Retraining of the left ventricle in congenitally corrected TGA or after Senning or Mustard operation is necessary when right-ventricular failure is developing and an arterial switch operation is indicated. As these hearts have little tolerance of marginal overbanding, a long-term adjustable pulmonary artery banding device would lower stress and risk of training. Although the inserted device (Osypka) allowed convenient intraoperative pressure ratio adjustment, mid-term adjustment failed due to dysfunction of the system.

Surgical banding of the pulmonary artery in patients with transposition of the great arteries leads to a rapid increase of the left ventricular mass. The purpose of this animal experiment was to induce ventricular systolic hypertension in the “subpulmonary ventriclerdquo; by intravascular obstruction to pulmonary flow. The first experiment was performed in an anesthetized animal with an open thorax. A balloon-tipped catheter was introduced into the femoral vein and advanced to the pulmonary artery. The balloon was positioned in the pulmonary trunk and was progressively inflated until a systemic pressure was achieved in the “pulmonary ventricle”. This was accomplished within 40 minutes without a significant reduction in cardiac output, which was continuously monitored by an electromagnetic flowprobe. In the second experiment an analogous procedure was performed in a closed chest, awake, spontaneously breathing animal. The catheter was maintained in proper place for 24 hours. Subsequent macroscopic examination of the heart demonstrated a remarkable increase in the ventricular mass. The results of this preliminary experiment demonstrate the possibility for creating “intraluminal pulmonary banding”. The potential advantages of this technique are the nonsurgical approach and the ability to adjust the grade of obstruction to pulmonary flow.
