BACKGROUNDnA percentage of patients with a left ventricular assist device (LVAD) require device exchange. Although this is an important clinical entity, there are only a handful of relevant studies on this topic in the literature.nnnMETHODSnFrom 2004 to 2012, 30 device exchanges (HeartMate II to HeartMate II) were performed. Since June 2011, we have employed the subcostal approach for device exchange if indicated. Sixteen patients underwent device exchange through a subcostal approach (S group), whereas 14 patients had devices exchanged through a full sternotomy (F group). Pre- and post-operative data were retrospectively reviewed.nnnRESULTSnThere was no difference in baseline patient characteristics between the two groups. Overall, mean duration between primary surgery and device exchange was 425 ± 407 days. Surgical indications included device thrombus/hemolysis (N = 19), device malfunction (N = 9) and infection (N = 2). Cardiopulmonary bypass time was significantly shorter in the S group (S: 40 ± 23 minutes, F: 105 ± 84 minutes; p < 0.05), and post-operative bleeding within 24 hours after surgery was less in the S group (S: 362 ± 367 ml, F: 1,286 ± 971 ml; p < 0.05). Length of ICU stay was significantly shorter in the S group (S: 4.6 ± 1.8 days, F: 8.2 ± 4.9 days; p < 0.05). There was no difference in post-operative complications, except for prolonged intubation (F: N = 6 [43%], S: N = 1 [6.3%]; p < 0.05). There were 3 deaths in the F group and 0 in the S group, with no statistical difference (p = 0.09). Also, there was no significant difference in other outcomes, including transplantation, device explantation and ongoing LVAD support.nnnCONCLUSIONSnA subcostal approach may be preferred for HeartMate II device exchange if indicated.

BACKGROUNDnRepair of complete atrioventricular canal early in infancy has traditionally carried greater morbidity and mortality than repair performed later. However, an individualized anatomy-based repair may give young infants outcomes that are equivalent to older patients.nnnMETHODSnWe retrospectively reviewed 139 patients who underwent complete atrioventricular canal repair from January 2005 to December 2012. An individualized approach was used: 2-patch repair was performed in 98 patients for large ventricular septal defects and a modified single-patch (Australian technique) was used in 41 for shallow ventricular septal defects.nnnRESULTSnThe average age was 25.5 ± 3.9 weeks, 50% were boys, and 78% had trisomy 21. Mean follow-up was 5.1 ± 0.2 years, with 100% completeness of data. There were 3 in-hospital deaths (2.1%) and 1 late death (0.7%). A permanent pacemaker was required in 2 patients (1.4%). The rate for left atrioventricular valve reoperation was 8% at a mean of 211 ± 238 days after the original repair (range, 6 to 682 days). Compared with patients aged older than 3 months, the 39 patients (28%) who were younger than 3 months had similar perioperative courses and rate of reoperation. Compared with patients with an Australian repair, the 98 patients (71%) with a 2-patch repair were more likely to have trisomy 21 and had slightly increased cardiopulmonary bypass and cross-clamp times but similar outcomes. Multivariate analysis showed postoperative left atrioventricular valve regurgitation greater than 2 and left ventricular outflow tract obstruction were significant risk factors for reoperation on the left atrioventricular valve (both p < 0.05).nnnCONCLUSIONSnRepair of complete atrioventricular canal using an individualized surgical approach yields reoperation and early mortality rates similar for younger infants compared with older infants, obviating the need to delay operation in symptomatic patients.

A strong component of predicted mortality in scoring systems is advanced age, however, outcomes data in nonagenarians (age >90 years) is lacking. We evaluated surgical outcomes after aortic valve replacement (AVR) in nonagenarians at our institution over an 11-year period.nnDemographics, procedural
