Randomized Controlled Trial Multicenter Study Comparative StudyCost-effectiveness of ablation surgery in patients with atrial fibrillation undergoing cardiac surgery.
This study was performed to assess the cost-effectiveness of concomitant ablation surgery (AS) compared to regular cardiac surgery in atrial fibrillation (AF) patients over a one-year follow-up. Cost analysis was performed from a societal perspective alongside a prospective, randomised, double-blinded, multicentre trial. One hundred and fifty patients with documented AF were randomly assigned to undergo cardiac surgery with or without AS. ⋯ The incremental cost-effectiveness ratio is €73,359 per QALY. The acceptability curve showed that, even in the case of a maximum threshold value of €80,000 per QALY gained, the probability of AS being more cost-effective than regular cardiac surgery did not reach beyond 50%. Concluding that concomitant AS in AF is not cost-effective after a one-year follow-up compared to regular cardiac surgery.

Case ReportsRight pulmonary artery agenesis and coronary-to-bronchial artery aneurysm.
Isolated unilateral pulmonary artery agenesis is a rare congenital anomaly that may be complicated with hemoptysis, recurrent pulmonary infections or pulmonary hypertension. To our knowledge the occurrence of a coronary syndrome associated with a coronary-to-bronchial artery saccular aneurysmal collateralization has never been described before. A 44-year-old female presented a congenital right pulmonary artery agenesis associated with a hypotrophic and multicystic right lung complicated with recurrent bronchitis. ⋯ We first performed an embolization of those two aneurysms in order to decrease the risk of hemorrhage and coronary steal, before performing a right pneumonectomy. In this case, the surgery was indicated because of the pathological lung and the risk of postembolization ischaemia. The postoperative course was uneventful and the patient was doing well six months later.

Valve-sparing aortic root replacement in children: intermediate-term results.
Valve-sparing root replacement (VSRR) is an attractive option for aortic aneurysm in children with low-operative risk, but mid- and late-term results are not yet known. Between 1997 and 2009, 56 children (mean age 11.5 years) underwent VSRR at our institution. Twenty-six (46.4%) had Marfan syndrome and 24 (42.8%) had Loeys-Dietz syndrome. ⋯ No patient developed >2+ AI after reimplantation. VSRR in children is a safe alternative to aortic root replacement with mechanical or biological prostheses. In this particular group of patients with connective tissue disorders and proclivity toward annular dilation and late AI, reimplantation is superior to remodeling.

Cardiac surgery in low birth weight infants: current outcomes.
Low birth weight (LBW) is a risk factor for mortality in neonatal and infant heart surgery. The purpose of this study was to determine the contemporary outcomes and risk factors of cardiac surgery in low weight babies. The records of 75 consecutive infants weighing <2.5 kg having heart surgery were reviewed. ⋯ Age, prematurity, preoperative mechanical ventilation, prostaglandins, non-cardiac organ dysfunction, extra-cardiac malformations, perioperative extracorporeal membrane oxygenation (ECMO), and type of procedure were not associated with significant differences in mortality. Cardiac surgery in LBW infants can be performed with low early and mid-term mortality. LBW infants with chromosomal/genetic anomalies have a higher risk.
