We discuss 4 cases of plastic bronchitis (PB) after Fontan procedure observed at our Institution, with the aim to identify an effective treatment and possible factors favoring the onset of PB. Plastic bronchitis is an uncommon disease characterized by recurrent formation of large pale bronchial casts obstructing the tracheobronchial tree. The treatment includes inhaled or systemic steroids, aerosolized mucolytics, bronchoscopic lavage, direct bronchoscopic extraction and, in few reports, aerosolized fibrinolytic and pulmonary vasodilators. ⋯ The exact causes of PB in Fontan patients remain unknown. An early diagnosis and a multiple therapy with steroids, mucolytics, pulmonary vasodilators, and aerosolized tissue plasminogen activator may be effective.

Acute high-risk pulmonary embolism is a life-threatening condition with high early mortality rates resulting from acute right ventricular failure and cardiogenic shock. We retrospectively analyzed the outcomes of surgical embolectomy among patients with circulatory collapse. ⋯ Surgical pulmonary embolectomy is an excellent approach to treating acute pulmonary embolism with circulatory collapse. Providing immediate percutaneous cardiopulmonary support to patients with cardiogenic shock could help to resuscitate and stabilize cardiopulmonary function and allow for a good outcome of pulmonary embolectomy.

Comparative Study
Are thromboembolic and bleeding complications a drawback for composite aortic root replacement?
Valve-preserving aortic root reconstruction is being performed with increasing frequency. Independent of durability concerns, enthusiasm for retaining the native valve is often championed on the presumption that composite graft replacement of the aorta will be complicated by thromboembolism and bleeding. Our goal in this late follow-up study is to determine if thromboembolism or bleeding, or both, are indeed problematic after composite aortic root replacement. ⋯ Patients had excellent survival and few thromboembolic and bleeding complications after composite aortic root replacement. These data supporting minimal morbidity in the setting of well-established durability should be used to put alternative procedures, such as valve-preserving aortic root reconstruction, into context.

Trends in the indications and survival in pediatric heart transplants: a 24-year single-center experience in 307 patients.
Heart transplantation is the only viable treatment for children with end-stage heart failure due to congenital heart disease (CHD) or cardiomyopathy. This study reviewed the trends in the indications for transplant and survival after transplant during the past 24 years. ⋯ Transplantation for heart failure related to failed SV palliation has become the most common indication for patients with CHD. The high-risk nature of these transplants will have significant implications for heart transplant programs as more infants with SV anomalies survive palliative procedures performed during infancy.

Comparative Study
Early and late results of graft replacement for dissecting aneurysm of thoracoabdominal aorta in patients with Marfan syndrome.
When treating dissecting aneurysm of the thoracoabdominal aorta surgically in patients with Marfan syndrome, we have usually performed graft replacement- including the entire thoracoabdominal aorta and reconstruction of all visceral branches, even if dilatation is mild in some segments-to avoid further aortic operations in the follow-up period. ⋯ Graft replacement for dissecting aneurysm of the thoracoabdominal aorta in Marfan syndrome offers good early and long-term results. We believe total aortic replacement including the entire thoracoabdominal aorta and reconstruction of all visceral arteries should be recommended for selected patients with Marfan syndrome.
