Percutaneous Transseptal Bioprosthetic Implantation in Failed Prosthetic Surgical Mitral Valve - Brazilian Multicenter Experience.

Background: Percutaneous intervention in patients with bioprosthetic mitral valve dysfunction is an alternative to conventional surgical treatment.

Objectives: To report the first Brazilian experience with transseptal transcatheter bioprosthetic mitral valve-in-valve implantation (transseptal-TMVIV).

Methods: Patients with surgical bioprosthetic dysfunction submitted to transseptal-TMVIV in 12 Brazilian hospitals were included.

Hybrid Treatment with Complete Transposition of Supra-Aortic Trunks versus Conventional Surgery for the Treatment of Aortic Arch Aneurysm.

Objective: The disease of the aortic arch is traditionally approached by open surgical repair requiring cardiopulmonary bypass and circulatory arrest. This study performed a retrospective analysis comparing outcomes through primary hybrid patients submitted to aortic arch surgery without cardiopulmonary bypass with patients submitted to conventional open surgery.

Methods: 25 patients submitted to the aortic arch surgery were selected in the period 2003-2012 at the Madre Teresa Hospital in the city of Belo Horizonte, Brazil; 13 of these underwent hybrid technique without cardiopulmonary bypass and 12 underwent conventional open surgery.

Incidence of deep vein thrombosis and quality of venous thromboembolism prophylaxis.

Objective: to determine the incidence of deep vein thrombosis and prophylaxis quality in hospitalized patients undergoing vascular and orthopedic surgical procedures.

Methods: we evaluated 296 patients, whose incidence of deep venous thrombosis was studied by vascular ultrasonography. Risk factors for venous thrombosis were stratified according the Caprini model.

Treatment of Hostile Proximal Necks During Endovascular Aneurysm Repair.

Endovascular aneurysm repair (EVAR) is a therapy that continues to evolve rapidly as advances in technology are incorporated into new generations of devices and surgical practice. Although EVAR has emerged as a safe and effective treatment for patients with favorable anatomy, treatment of patients with unfavorable anatomy remains controversial and is still an off-label indication for endovascular treatment with some current stent-grafts. The proximal neck of the aneurysm remains the most hostile anatomic barrier to successful endovascular repair with long-term durability.

Results of Castro Bernardes intraluminal ring in surgery for ascending aortic aneurysms and dissections.

Objective: To demonstrate surgical results using Castro Bernardes intraluminal ring in ascending aorta surgery, instead of conventional suture.

Methods: 95 patients underwent ascending aorta surgery from December 2008 to April 2011 at Madre Tereza Hospital (Belo Horizonte, MG, Brazil), using Castro Bernardes intraluminal ring instead of conventional suture of the aorta.

Results: Ninety five patients underwent ascending aorta surgery with Castro-Bernardes intraluminal ring.
