Aortoarteritis is the most common cause of renovascular hypertension in South Asian children. PTRA is safe and highly effective and therefore should be the treatment of choice in pediatric renovascular hypertension.

Younger age, malnutrition, preoperative respiratory tract infection, high American anesthesiology score, longer duration of surgery, prolonged ventilation, and ICU stay were definite risk factors for mediastinitis. Early primary closure over drains, vacuum-assisted closure, muscle flap, and omental flap remain the most frequently performed treatments for post-sternotomy mediastinitis. Vacuum-assisted closure has emerged as the technique of choice in recent years.

Biatrial involvement or multiplicity of myxomas does not mandate recurrence. Surgical excision has excellent overall survival and freedom from reoperation rates, but annual follow-up including echocardiographic surveillance is recommended as familial cases tend to recur.

Dehiscence of the sternum is a serious and potentially devastating complication. The purpose of this prospective study was to determine whether a prophylactic sternal weave would decreased the incidence of noninfective sternal dehiscence, compared to routine sternal closure, in a high-risk group. Between 2000 and 2007, 200 patients undergoing median sternotomy for cardiac surgery, with one or more risk factors including New York Heart Association functional class III/IV, chronic obstructive pulmonary disease, osteoporosis, obesity, and off-midline sternotomy, were randomly assigned to group A (sternal weave closure, 100 patients) or group B (routine sternal wire closure, 100 patients). No patient in either group with a single risk factor had sternal dehiscence. The incidence of noninfective sternal dehiscence was significantly less in group A than group B in patients with 2 or more risk factors (2.5% vs. 12.5%). Routine sternal closure is sufficient in patients with a single risk factor, whereas a prophylactic sternal weave should be carried out in all patients with 2 or more risk factors, to decrease postoperative morbidity.
