Anomalous Pulmonary Venous Return

Sinus venosus atrial septal defect (ASD) is usually associated with partial anomalous pulmonary venous return (PAPVR) of the right pulmonary veins to the superior vena cava (SVC), or to the SVC-right atrial junction. Standard procedure for repair of this defect is a patch roofing of the sinus venosus ASD and rerouting of pulmonary veins. However, the presence of SVC stenosis is a complication of this technique, and SVC augmentation is necessary in some cases. We present a simple technique for concomitant closure of sinus venosus ASD associated with PAPVR and augmentation of the SVC with a single autologous pericardial patch.

Pediatric Cardiac Surgery

Objective One of the major challenges faced in minimally invasive pediatric cardiac surgery is cannulation strategy for cardiopulmonary bypass. Central aortic cannulation through the same incision has been the usual strategy, but it has the disadvantage of cluttering of the operative field. We hereby present the results of femoral cannulation in minimally invasive pediatric cardiac surgery in terms of adequacy and safety. Methods From January 2013 to June 2016, 200 children (122 males) with mean ± SD age of 9.2 ± 4.51 years (median = 6 years, range = 3–18 years) and weight of 19.22 ± 8.49 kg (median = 15 kg, range = 8–45 kg) were operated for congenital cardiac defects through anterolateral thoracotomy. The most common diagnosis was atrial septal defect (144 patients). In all the patients, femoral artery and femoral vein were cannulated along with direct superior vena cava cannulation for institution of cardiopulmonary bypass. Results There were no deaths or any major complications related to femoral cannulation. Femoral artery cannulation provided adequate arterial inflow, whereas femoral vein with direct superior vena cava cannulation provided adequate venous return in all the patients. No patient required vacuum-assisted venous drainage. No patient required conversion to sternotomy or developed vascular, neurological complications. At discharge and at 1-year follow-up, both femoral artery and vein were patent without a significant stenosis on color Doppler ultrasonography in all the patients. At mean ± SD follow-up period of 30.63 ± 10.09 months, all the patients were doing well without any wound-related, neurological, or vascular complications. Conclusions Femoral arterial and venous cannulation is a feasible, reliable, and efficient method for institution of cardiopulmonary bypass in minimally invasive pediatric cardiac surgery.

Objective Inadequate peripheral venous drainage during minimally invasive cardiac surgery (MICS) is a challenge and cannot always be solved with increased vacuum or increased centrifugal pump speed. The present study was designed to assess the benefit of virtually wall-less transfemoral venous cannulas during MICS. Methods Transfemoral venous cannulation with virtually wall-less cannulas (3/8″ 24F 530–630-mm ST) was performed in 10 consecutive patients (59 ± 10 years, 8 males, 2 females) undergoing MICS for mitral (6), aortic (3), and other (4) procedures (combinations possible). Before transfemoral insertion of wall-less cannulas, a guidewire was positioned in the superior vena cava under echocardiographic control. The wall-less cannula was then fed over the wire and connected to a minimal extracorporeal system. Vacuum assist was used to reach a target flow of 2.4 l/min per m2 with augmented venous drainage at less than −80 mm Hg. Results Wall-less venous cannulas measuring either 630 mm (n = 8) in length or 530 mm (n = 2) were successfully implanted in all patients. For a body size of 173 ± 11 cm and a body weight of 78 ± 26 kg, the calculated body surface area was 1.94 ± 0.32 m2. As a result, the estimated target flow was 4.66 ± 0.78 l/min, whereas the achieved flow accounted for 4.98 ± 0.69 l/min (107% of target) at a vacuum level of 21.3 ± 16.4 mm Hg. Excellent exposure and “dry” intracardiac surgical field resulted. Conclusions The performance of virtually wall-less venous cannulas designed for augmented peripheral venous drainage was tested in MICS and provided excellent flows at minimal vacuum levels, confirming an increased performance over traditional thin wall cannulas. Superior results can be expected for routine use.
