This study aims to analyze survival, repeat hospitalization, and risk factors for surgically treated left-sided endocarditis. Retrospective review of all 166 (114 native and 52 prosthetic) patients operated between January 2004 and March 2015 was performed. Long-term survival and repeat hospitalization data for 134 of 166 patients were obtained via linked clinical databases with the Manitoba Centre for Health Policy. Kaplan-Meier estimates of survival and hospital readmission and Cox multivariable regression analysis of factors influencing outcomes were performed...

BACKGROUND: Reoperative cardiac valve surgery via sternotomy is associated with a substantial morbidity and mortality. This study evaluated the right anterolateral thoracotomy for high-risk patients undergoing mitral and tricuspid valve redo procedures. METHODS: Out of a series of 173 patients undergoing redo cardiac valve surgery, 24 patients were reoperative via the right anterolateral thoracotomy as the high-risk group on the basis of the proximity of the heart and great vessels to the sternum and the presence and location of patent bypass grafts...

AIMS: To test the feasibility of trans-catheter mitral valve implantation of the NaviGate device in acute and chronic preclinical models. METHODS AND RESULTS: We evaluated the NaviGate valved stent implantation in the mitral position in an acute swine model (n=24, ≤ 5 days) through three different approaches: trans-atrial, trans-apical, and trans-septal, and in a chronic swine model (n=12, >10 days) through a trans-atrial approach. The NaviGate implantation procedures were successful in 83% of the acute model studies (n=20) and 83% of the chronic model studies (n=10)...

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...

: Paravalvular leak (PVL) is an uncommon but serious complication associated with the implantation of prosthetic valves. Following aortic valve replacement, up to 5% of patients affected by PVL develop clinical symptoms of heart failure, hemolysis or both. Percutaneous treatment of PVL has emerged instead of conventional surgery, as a well tolerated and less invasive procedure but remains a challenge. We present the case of a young woman with mechanical aortic and mitral prostheses, who presented surgical aortic PVL caused by a serious frailty of native annulus, became symptomatic after 5 months and was successfully percutaneously treated with an Amplatzer Duct Occluder device...

Severe aortic stenosis (AS) and mitral regurgitation (MR) frequently coexist. Although some observational studies have reported that moderate or severe MR is associated with higher mortality, the optimal management of such patients is still unclear. Simultaneous replacement of both aortic and mitral valves is linked to significantly higher morbidity and mortality. Recent advances in minimally invasive surgical or transcatheter therapies for MR allow for staged procedures in which surgical or transcatheter aortic valve replacement (SAVR/TAVR) is done first and MR severity re-evaluated afterwards...

In the United States, valvular heart disease (VHD) has a prevalence of 2.5%, most commonly presenting as aortic stenosis (AS) or mitral valve regurgitation (MR) and increasingly observed to be of a degenerative etiology. Women frequently have latent symptoms despite significant disease, and it is therefore pertinent to consider both clinical symptoms and imaging findings for decision-making on treatment. Indeed, significant advances have been made in noninvasive imaging allowing for more accurate diagnosis and disease prognostication...

BACKGROUND: Aortic valve replacement in a patient with an aortic homograft can be very challenging, especially when concomitant mitral valve surgery needs to be performed. CASE PRESENTATION: We report a case of implantation of a sutureless aortic valve bioprosthesis combined with mitral valve replacement in a patient with a severely calcified aortic homograft where conventional valve replacement was technically unfeasible. CONCLUSIONS: We believe that sutureless AVR is a viable option especially for young patients with a high surgical risk where conventional valve replacement cannot be achieved...

We describe the case of a 57-year-old man who had severe mitral valve stenosis and regurgitation without significant annular calcification. He was not a candidate for surgical valve replacement or repair because of his substantial comorbid conditions, overall frailty, and elevated surgical risk. He underwent successful transcatheter mitral valve replacement of his native mitral valve with compassionate, off-label use of an Edwards Sapien 3 valve. A search of the literature produced no other cases like ours, which represents a further evolution of the transcatheter valve implantation concept...

BACKGROUND: Mitral valve replacement is the procedure of choice in patients with severe mitral valve disease. However, these patients are surviving longer and are thus at an increased risk of prosthesis failure or valve-related complications. METHOD: Study setting: Inkosi Albert Luthuli Central Hospital, a tertiary referral Hospital in Durban. Study population: All patients undergoing redo mechanical mitral valve replacement surgery between January 2005 and December 2014...

Prosthetic valve paravalvular leak (PVL) is a known and relatively common complication of surgical valve replacement, which may lead to significant morbidity. Patients with significant mitral valve replacement (MVR) PVL typically present with symptoms of heart failure and elevated filling pressures or with hemolytic anemia. Percutaneous closure of these leaks has become the preferred therapy. Percutaneous closure of MVR PVL can be technically challenging, given the anatomy of the approach (trans-septal, trans-apical), the level of associated comorbidities and the geographic location of the paravalvular defect...

Obstructive prosthetic valve thrombosis (PVT) is a rare but severe complication that usually occurs in the presence of suboptimal anticoagulation. Although fluoroscopy is commonly used to detect abnormal leaflet motion as a surrogate marker for PVT, its inability to directly visualize adjacent tissue and valve physiology leaves it susceptible to miss clinically important PVT. In this manuscript, we report the case of a 54-year-old woman with a mechanical mitral valve who was admitted to our institute with exertional dyspnea...
