Uncommonly, adults with functionally univentricular hearts are becoming candidates for a Fontan procedure. The purpose of this study was to evaluate the course of patients undergoing the modified Fontan procedure with an extracardiac conduit in recent years. ⋯ The modified Fontan procedure with use of an extracardiac conduit can be performed in adults with encouraging early and midterm results. The majority of late survivors had improved quality of life. The incidence of late death, reoperation, arrhythmias, and thromboembolic events was low during follow-up.

Review Case Reports
Giant left ventricular thrombus formation associated with heparin-induced thrombocytopenia.
A 33-year-old man underwent urgent coronary artery de-obstruction for acute thrombotic occlusion of the left descending coronary artery. After 10 days of antiplatelet and heparin therapy, ventriculographic and echocardiographic control revealed a giant thrombus in the left ventricle, an ejection fraction of 40%, and severe mitral regurgitation. ⋯ After urgent mitral valve annuloplasty and left ventricular thrombectomy, the patient was discharged. In the literature, several cases of right atrial and ventricular thrombi have been described; however, to the best of our knowledge, this is the first report of giant left ventricular thrombus during heparin-induced thrombocytopenia.

Multicenter Study
The association of transcatheter aortic valve replacement availability and hospital aortic valve replacement volume and mortality in the United States.
Whether the introduction of transcatheter aortic valve replacement (TAVR) has affected hospitals' surgical aortic valve replacement (SAVR) and overall aortic valve replacement (AVR) case volumes and outcomes in the United States is unknown. ⋯ Since the introduction of TAVR, the total volume of AVR procedures, including higher overall use of SAVR, at TAVR sites has significantly increased in the United States. Overall, in-hospital survival of patients undergoing treatment for aortic valve stenosis continues to improve.

Multicenter Study
Epidemiology and outcomes after in-hospital cardiac arrest after pediatric cardiac surgery.
Multicenter data regarding cardiac arrest in children undergoing heart operations are limited. We describe epidemiology and outcomes associated with postoperative cardiac arrest in a large multiinstitutional cohort. ⋯ Cardiac arrest carries a significant mortality risk across the stratum of procedural complexity. Although arrest rates are not associated with center volume, lower-volume centers have increased mortality after cardiac arrest. Further study of mechanisms to prevent cardiac arrest and to reduce mortality in those with an arrest is warranted.

Multicenter Study
Survival benefit of lung transplantation for chronic obstructive pulmonary disease in Sweden.
Lung transplantation (LTx) is a therapeutic option for patients with life-threatening chronic obstructive pulmonary disease (COPD) that is refractory to conventional therapies. The survival benefit of LTx for COPD is difficult to assess. The aim of this study was to evaluate the Swedish series of LTx performed to treat COPD and to identify differences in outcome between COPD related to severe alpha-1-antitrypsin deficiency (AATD) and COPD with normal alpha-1-antitrypsin (AAT) levels. ⋯ Survival after LTx is significantly better for patients with severe AATD and end stage COPD than for the patients with COPD related to cigarette smoking.
