This retrospective study evaluated whether a systemic-PA shunt in infants with TOF facilitated enlargement of the pulmonary valve annulus (PVA).  Placement of a shunt was the only factor associated with PVA growth.  This knowledge may affect how repair is staged with an eye towards avoiding a transannular patch.

Semiautomated CT volumetric measurements of tumor volume in patients with malignant pleural mesothelioma were compared to stage and overall survival.  CT volumes correlated well with stage and survival.

This analysis of PARTNER data evaluated the impact of chronic kidney disease (CKD) on outcomes after TAVR.  Patients were grouped according to GFR as none/mild, moderate, and severe renal disease.  Severe disease was most common among women with diabetes.  Severe disease was associated with a 50% increase in 30-day mortality and 1-year cominbed mortality and all-cause rehospitalization.  Assessment of renal function may help risk stratify patients who are candidates for TAVR.

The authors conducted a meta-analysis of propensity-scored matched patients in published studies to assess outcomes of right internal mammary artery (RIMA) and radial artery (RA) as second conduits for CABG.  Eight studies included nearly 3000 matched pairs.  RITA was associated with better long-term survival and freedom from reoperation, but also was associated with an increased risk of sternal wound infection when pedicled harvest was conducted.   See also:

This single institution retrospective review assessed outcomes of AVR in patients with concomitant aortic root disease using a composite graft.  Early mortality was 5.3% and was related to advanced age, poor NYHA status, urgent operation, and associated MVR or CABG.  Late death was related to CRI, COPD, aortic dissection, CABG, and use of the Cabrol technique.  10-year survival was 66%.

The success of training techniques including dividing robotic lobectomy into graduated steps, reviewing video peformances of trainees, and coaching through challenging technical maneuvers were tracked during a 5-year experience.  Performance of individual steps among general surgery and cardiothoracic surgery trainees increased over time, while metrics of outcomes remained the same or improved.

MRI assessment of cerebral blood flow and calculated cerebral oxygen delivery were compared between neonates with congenital heart disease and normal controls.   Although cerebral blood flow was similar between the groups, oxygen delivery was over 30% lower in neonates with congenital heart disease, primarily because of arterial desaturation.  These findings may influence the timing of repair of congenital heart disease.

The authors assessed the relationship between second hand smoke exposure in non-smokers and mortality related to lung cancer using serum cotinine levels.  Cotinine levels were associated with survival, death from lung cancer, and death from all cancers after adjustment.  Such levels identify second hand smoke effects.

The Duke group analyzed their group of patients undergoing proximal aortic operations during a 9-year period (n=869) to determine the incidence and etiology of reintervention on the aorta during follow-up.  In all, 4.32% of patients required reintervention—roughly evenly divided between the proximal ascending aort and the distal aorta—and most occured within 3 years.  The type of intervention needed in the second setting varied based upon the indications for, and type of, initial operation.

The authors performed a subgroup analysis of the Papillary Muscle Approximation (PMA) trial, a randomized trial that, while showing superiority of PMA + restrictive annuloplasty (RA) over RA alone in terms of LV remodeling and MR recurrence, failed to show a survival advantage and was plagued by a relatively high incidence of reoperation.  In this study, the authors found that the best outcomes were seen in patients with preop symmetric tethering, asymmetric tethering, or inferior wall dyskinesia.  Patients with primarily anterolateral wall dysfunction did not benefit from the addition of the PMA.
