Constrictive pericarditis has multiple etiologies and can lead to disabling symptoms and severe heart failure with poor quality of life. Surgical pericardiectomy is the cornerstone of management. All patients undergoing pericardiectomy at our institution were reviewed with the goal of analyzing preoperative and intraoperative factors that may be associated with long-term outcomes. ⋯ Pericardiectomy can be performed with low mortality and immediate improvement in hemodynamics. Those patients with compromised cardiac output, abnormal hepatic or renal function, or with previous radiation therapy have reduced long-term survival.

Mitral valve operations are increasingly performed through minimally invasive approaches such as the right anterior minithoracotomy. To facilitate exposure with this technique, a diaphragmatic suture may be implemented. We describe a liver laceration caused by the diaphragmatic suture in minithoracotomy mitral repair and its successful nonoperative management with arterial embolization.

We present a case of total occlusion of the superior vena cava (SVC) with extensive thrombosis of the adjacent large veins secondary to multiple abandoned pacemaker leads with a superimposed chronic lead infection by Corynebacterium jeikeium. A surgical lead extraction was performed with an extensive en-bloc resection of the SVC together with the right subclavian vein and the right innomate vein. No venous reconstruction was required because of an unobstructed runoff via a well-developed azygos system.

Comparative Study
Beyond the learning curve: transapical versus transfemoral transcatheter aortic valve replacement in the treatment of severe aortic valve stenosis.
Most studies comparing transapical and transfemoral transcatheter aortic valve replacement include the center's early operative experience, which may negatively impact the outcomes. This study reports our experience beyond the learning curve with transapical and transfemoral transcatheter aortic valve replacement. ⋯ Transapical transcatheter aortic valve replacement is associated with less prevalence of vascular complications and mild-moderate paravalvular regurgitation in comparison to the transfemoral approach. Further study is necessary to determine if the transapical technique is the preferred option. doi: 10.1111/jocs.12323 (J Card Surg 2014;29:303-307).
