Comparative StudyOptimized ventricular restraint therapy: adjustable restraint is superior to standard restraint in an ovine model of ischemic cardiomyopathy.
The effects of ventricular restraint level on left ventricular reverse remodeling are not known. We hypothesized that restraint level affects the degree of reverse remodeling and that restraint applied in an adjustable manner is superior to standard, nonadjustable restraint. ⋯ Restraint level affects the rate and degree of reverse remodeling and is an important determinant of therapy efficacy. Adjustable restraint is more effective than nonadjustable restraint in promoting reverse remodeling.

Surgical treatment of metachronous second primary lung cancer after complete resection of non-small cell lung cancer.
To clarify the perioperative and oncologic outcome of pulmonary resection for a metachronous second primary lung cancer (MSPLC) following resection of an initial non-small cell lung cancer (NSCLC). ⋯ Surgical treatment of a MSPLC can be undertaken with 5-year survival rate of 60%. Expected operative morbidity and mortality are comparable to primary surgery. Tumors 2 cm or smaller are associated with improved survival and freedom from recurrence. Close long-term follow-up of patients who have undergone resection of NSCLC is recommended.

Comparative StudySurgery for acute type A aortic dissection in octogenarians is justified.
Surgery in octogenarians with acute type A aortic dissection is commonly avoided or denied because of the high surgical morbidity and mortality reported in elderly patients. We sought to compare clinical and quality of life outcomes between octogenarians and those aged less than 80 years who underwent surgical repair at New York Medical College. ⋯ Surgery for acute type A aortic dissection should be offered to octogenarians because excellent surgical and quality of life outcomes can be achieved even in this elderly population.

Long-term results of aortic root repair using the reimplantation technique.
Aortic valve sparing is frequently performed to treat patients with aortic root aneurysm, but there is an inadequate amount of information regarding its long-term durability. This study examines the long-term results of reimplantation of the aortic valve in patients with aortic root aneurysms. ⋯ The function of the aortic valve implanted inside a tubular Dacron graft remains normal at 15 years in most patients after this type of aortic valve-sparing operation.

Reintervention for endograft failures after thoracic endovascular aortic repair.
Thoracic endovascular aortic repair has emerged as an effective therapy for a variety of thoracic aortic pathologic entities. However, endograft failure remains a concern, and its treatment is often challenging. We examined our experience with endograft failure and its treatment by endovascular and open repair. ⋯ Reintervention for endograft failure can be performed with acceptable early outcomes. The mid-term survival for patients requiring reintervention for endograft failure was similar to that of the patients without endograft failure. Thus, reintervention for endograft failure should be aggressively considered when indicated.
