Management of aortic valve disease and, in particular, aortic valve stenosis has evolved through the course of time from medical management and balloon valvuloplasty to the presumed gold-standard surgical intervention. However, with the advent of surgical innovation, intra- and postoperative patients monitoring, understanding of hemodynamic dysfunction, and choices of prosthesis, conventional surgical aortic valve replacements are currently being challenged in particular in moderate- and high-risk patients...

We present our experience for patients who have undergone an anatomic repair (AR) for congenitally corrected transposition of the great arteries (CCTGA) at the Children's Hospital of Wisconsin. A retrospective chart review of patients who underwent AR for CCTGA from 2001 to 2015 was performed. The cohort consisted of 15 patients (74% male). Median age of anatomic repair was 15 months (range 4.5-45.6 months). Four patients had a bidirectional Glenn (BDG) prior to AR. At the time of AR,-9 (60%) underwent Senning/Rastelli procedure, 4 (26...

The combination of ruptured aneurysm of the sinus of Valsalva and a bicuspid aortic valve is very rare in an elderly person. A 71-year-old man with ruptured aneurysm of the sinus of Valsalva and a bicuspid aortic valve had undergone an operation. He was admitted to his other hospital because of heart failure. He was transferred to our hospital to undergo treatment for ruptured aneurysm of sinus of Valsalva. At our hospital, echocardiography findings showed ruptured aneurysm of the sinus of Valsalva, a ventricular septal defect (VSD), and severe aortic regurgitation with moderate stenosis of the bicuspid aortic valve...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

PURPOSE: Left ventricular outflow tract (LVOT) dimensions are important for calculation of aortic valve areas and planning of valve repair. Mostly, LVOT areas are calculated from echocardiographic longitudinal measurements with the assumption of a round shape. Here, orthogonal phase contrast (PC) MRI with dynamic assessment of LVOT was compared to standard longitudinal cine MRI and 2D echocardiography. METHODS: In 19 patients with aortic stenosis (5 female; 69±10years), LVOT areas were determined on orthogonal PC images, either by planimetry (Aplan) or by two-diameter measurement (Aellip)...

Ascending aorta aneurysms (AsAA) are associated with a degeneration of the aortic wall tissue, which leads to changes in tissue mechanical properties. Risk factors for the development of the AsAA disease are recognized in patient age and gender, valve type, hypertension, diabetes mellitus, smoking history, and a prior diagnosis of Marfan syndrome. The present study aims to assess how such clinico-pathological factors can affect the mechanical properties of human dilated ascending aorta. Specimens of AsAA are excised from 68 patients who underwent elective AsAA surgical repair and stretched until rupture during the execution of uniaxial tensile tests...

OBJECTIVES: Any aortic valve (AoV) operation in children (repair, Ross or mechanical replacement) is a palliation and reinterventions are frequent. AoV repair is a temporary solution primarily aimed at allowing the patient to grow to an age when more definitive solutions are available. We retrospectively analysed AoV repair effectiveness across the whole age spectrum of children, excluding neonates and AoV disease secondary to congenital heart disease. METHODS: From 2003 to 2015, 193 consecutive patients were included...

OBJECTIVES: To summarize the published data of combined transcatheter aortic and mitral valve intervention (CTAMVI). BACKGROUND: CTAMVI, a combination of either transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve-in-valve (TAViV) and transcatheter mitral valve replacement (TMVR), transcatheter mitral valve-in-valve/valve-in-ring (TMViV/ViR), or percutaneous mitral valve repair (PMVR) is an attractive alternative in high-surgical risk patients with combined aortic and mitral valve disease...

PURPOSE: There remains a paucity of direct visualization techniques for beating-heart intracardiac procedures. To address this need, we evaluated a novel cardioscope in the context of aortic paravalvular leaks (PVLs) localization and closure. DESCRIPTION: A porcine aortic PVL model was created using a custom-made bioprosthetic valve, and PVL presence was verified by epicardial echocardiography. Transapical delivery of occlusion devices guided solely by cardioscopy was attempted 13 times in a total of three pigs...

BioGlue is a surgical adhesive widely used to help reinforce complex cardiac and vascular repairs. Since its introduction, several case reports have emerged revealing complications that all providers should be mindful of whenever the product is used. This report considers a unique situation where BioGlue was used after double cardiac valve repair that resulted in adhesion of the new mechanical aortic valve leaflets and was difficult to visualize with transesophageal echocardiography.

The purpose of this study was to evaluate the surgical results of papillary muscle approximation (PMA) and papillary muscle relocation (PMR) for functional mitral regurgitation (FMR) and to compare the effects of both procedures on the change in mitral regurgitation (MR) and echocardiogram parameters associated with tethering. Eighteen patients with moderate-to-severe FMR (MR grade ≥2) who underwent PMA or PMR were retrospectively analyzed. Underlying diseases were ischemic cardiomyopathy, idiopathic dilated cardiomyopathy, and aortic valve disease for seven, six, and five patients, respectively...

Functional tricuspid valve (TV) regurgitation secondary to left heart disease (e.g. mitral insufficiency and stenosis) is observed in 75% of the patients with TV regurgitation and is thus the most common etiology; therefore, the majority of patients who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe TV regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. Patients with moderate to severe TV regurgitation show a 3-year survival rate of 40%...

The Colvin-Galloway( CG) Future annuloplasty band is a new semirigid partial band, which was introduced in 2012 in Japan. A total of 60 consecutive patients who underwent mitral valve repair with the CG Future Band were assessed by echocardiography in terms of residual mitral regurgitation and diastolic mitral function postoperatively. Intraoperative 3-dimensional echocardiography beautifully demonstrated the physiological change of the aortic curtain during the cardiac cycle. 30 mm was used in 18 patients, 32 mm in 17, 28 mm in 15, 34 mm in 5, 36 mm in 2, and 26 mm in 2...

Acute heparin-induced thrombocytopenia (HIT) patients present a myriad of anticoagulation management challenges, in clinical settings where unfractionated heparin (UFH) is the traditional drug of choice. UFH use in cardiac surgery is a known entity that has been subject to rigorous research. Research has, thus, led to its unparalleled use and the development of well-established protocols for cardiac surgery. In comparison to UFH, bivalirudin use for acute HIT patients requiring urgent cardiac surgery with cardiopulmonary bypass (CPB) is still in its infancy...
