Surgical Repair of Anomalous Origin of the Left Subclavian Artery From the Pulmonary Artery Using a Supraclavicular Approach.

Anomalous origin of the left subclavian artery from the pulmonary artery is a rare congenital cardiac malformation. We describe a case of anomalous origin of the left subclavian artery from the pulmonary artery in a patient who presented with symptoms of vertebrobasilar insufficiency and underwent reimplantation of the left subclavian artery into the left common carotid artery from the supraclavicular approach.

Rigid Ring Versus Flexible Band for Tricuspid Valve Repair in Patients Scheduled for Mitral Valve Surgery: A Prospective Randomised Study.

BACKGROUND: Tricuspid valve repair for functional regurgitation is effectively performed with different annuloplasty devices. However, it remains unclear whether there are advantages associated with rigid rings compared to flexible bands. This prospective randomised study aimed to compare results of using a flexible band ring versus a rigid ring for functional tricuspid regurgitation in patients undergoing mitral valve surgery. METHODS: A single-centre randomised study was designed to allocate patients with functional tricuspid regurgitation undergoing mitral valve surgery to be treated with a flexible band or rigid ring. These patients were analysed by echocardiographic follow-up. The primary outcome was freedom from recurrent tricuspid regurgitation at 12-months follow-up. Secondary outcomes were 30-day mortality, survival, freedom from tricuspid valve reoperation, right ventricular reverse remodelling, and rate of major adverse events. RESULTS: A total of 308 patients were allocated to receive concomitant tricuspid valve annuloplasty with the flexible band or rigid ring. There was no between-group difference in freedom from recurrent tricuspid regurgitation: 97.3% in Rigid group (95% CI, 93.0-98.8) and 96.2% in the Flexible group (95% CI, 92.0-98.5) at 12-months follow-up (log-rank, p=0.261). Early mortality, survival, freedom from tricuspid valve reoperation, and global right ventricle systolic function were also comparable in both groups of patients. However, the flexible band had advantage in restoring regional right ventricle function (Doppler-derived systolic velocities of the annulus [S], tricuspid annular plane systolic excursion) at 12-months follow-up. CONCLUSION: Both the rigid ring and flexible band offered acceptable outcomes for functional tricuspid regurgitation correction without significant differences, as assessed at 12-months follow-up.

Vacuum-assisted closure versus closed irrigation for deep sternal wound infection treatment in infants: a propensity score-matched study.

OBJECTIVES: This study aimed to compare vacuum-assisted closure therapy (VAC) and closed irrigation drainage therapy (CID) for deep sternal wound infection treatment in infants. METHODS: From January 2008 to March 2018, 69 patients (1.73%) had deep sternal wound infection. They were divided into 2 groups: patients treated with VAC therapy (VAC group, 29 patients) and those treated with CID therapy (CID group, 40 patients). After performing a propensity score analysis (1:1) for the entire sample, 16 patients receiving VAC therapy were matched with 16 patients receiving CID therapy. RESULTS: No significant difference was noted between both groups regarding age [d = 0.045; 95% confidence interval (CI) 0.99-1.07], gender (d = 0.001; 95% CI 0.22-4.45), weight (d = 0.011; 95% CI 0.73-1.35), body surface area (d = -0.023; 95% CI 0.01-5733.08), cardiopulmonary bypass (d = 0; 95% CI 0.16-5.90) and open chest duration (d = -0.112; 95% CI 0.31-5.16). Five patients died in the CID group (31.25%) during hospital stay, and there were no deaths in the VAC group (P = 0.024). Recurrence of mediastinitis occurred in 1 patient (6.25%) from the VAC group and in 6 patients (37.5%) from the CID group (P = 0.037). The multivariable regression analysis revealed that the CID method was the only risk factor for remediastinitis (odds ratio 17.3; 95% CI 1.04-286.75; P = 0.046). CONCLUSIONS: Use of VAC therapy in infants with deep sternal wound infection was associated with a substantial decrease in the mortality rate and duration of therapy compared with CID technique. The CID technique was an independent risk factor for recurrence of mediastinitis.
