BACKGROUND: Cardiac valve disease is common in patients with end-stage heart failure undergoing left ventricular assist device implantation (LVAD). The aim of this study was to determine if preoperative mitral regurgitation (MR) affects outcomes and hemodynamics in patients after LVAD implantation. METHODS: From March 2006 through May 2015, 238 consecutive patients underwent LVAD implantation. Patient cohorts included less than moderate to severe MR (< moderate-severe, n = 195) and greater than or equal to moderate to severe MR (≥ moderate-severe, n = 43)...

A 74-year-old man with a history of mitral valve repair was referred to our hospital with fever and diagnosed with mitral valve endocarditis involving occlusion of the superior mesenteric artery. Bacterial cultures showed Staphylococcus lugdunensis. Despite antibiotic therapy, orthopnea ensued due to valve destruction. Emergency mitral valve replacement was performed. Computed tomography on postoperative day 10 revealed a rapidly expanding mycotic aneurysm of the superior mesenteric artery. Aneurysmectomy was undertaken...

The current non-resectional paradigm in mitral valve (MV) repair emphasizes the use of polytetrafluoroethylene (PTFE) for artificial chordal replacement. While excellent long-term durability of repair using PTFE neochordae has been established, there have been rare reports of neochordal rupture at various times after surgery. We report a case of artificial chordal rupture 10 years after anterior mitral leaflet repair, necessitating reoperation. This complication may have been precipitated by maldistributed intracardiac tensile forces as a consequence of a malpositioned annuloplasty band...

BACKGROUND: Although mitral valve repair is at present the technique of choice in mitral regurgitation (MR) due to degenerative valve disease, long term results in patients with active mitral infective endocarditis (IE) are still under evaluation. METHODS: In the study were included 34 consecutive patients (22 males; mean age, 60 years; range 32-84 years) referred to our institution between January 1, 2005 to December 31, 2011 who were treated with valve repair for mitral valve (MV) active infective endocarditis...

BACKGROUND: Adults with congenital heart disease (ACHD) undergoing systemic atrioventricular valve (SAVV) surgery are a complex, understudied population. We assessed midterm outcomes and prognostic factors in ACHD undergoing SAVV surgery. METHODS: We performed retrospective evaluation of ACHD undergoing SAVV surgery from January 2005 to February 2016: 14 (33%) patients with congenital mitral valve stenosis/regurgitation, 15 (35%) with atrioventricular septal defect (AVSD), and 14 (33%) with congenitally corrected transposition of the great arteries (ccTGA) with systemic tricuspid valve regurgitation...

Repeat cardiac surgery in patients with a previous sternotomy is associated with significant morbidity and mortality. While transcatheter aortic valve implantation in high risk surgical patients is now well established, experience with transcatheter mitral valve replacement is still at an early stage. Although many successful reports of transcatheter mitral valve replacements now exist, the predominant approach has been via a transapical approach. It is likely that, as with the evolution of favoured access routes for transcatheter aortic therapies, future directions for transcatheter mitral valves will focus on smaller delivery systems favouring the transvenous transseptal approach where possible...

INTRODUCTION: Balloon Mitral Valvuloplasty (BMV) with inoue balloon is the most common technique being followed worldwide. Over the wire BMV is a modified technique with Joseph Mitral Valvuloplasty (JOMIVA) balloon and is being followed in certain centres. We hypothesized that, the incidence and mechanism of Mitral Regurgitation (MR) is likely to be different from that of inoue balloon. AIM: To assess the mechanism and immediate clinical outcome of significant MR following BMV with JOMIVA balloon retrospectively...

A neonate with antenatally diagnosed severe aortic valve stenosis, left ventricular outflow tract obstruction, left ventricular endocardial fibroelastosis, and severe mixed mitral valve disease was admitted to our center for balloon aortic valvuloplasty. On day 49, we performed a Ross-Konno procedure and mitral valve replacement on the baby, whose weight was 3.4 kg. Right ventricle-to-pulmonary artery continuity was restored with a handmade trileaflet Gore-Tex conduit. We used a handmade cylindrical prosthesis made from decellularized equine pericardium in the mitral position...

We report about the first-in-man implantation of the Mitra-SpacerTM (Cardiosolutions Inc., West Bridgewater, MA/USA). It was implanted transapically. FMR was reduced to moderate degree. At two-months, while in NYHA II, LVEF had improved, but FMR increased and 2mL was added, reducing FMR to mild degree. Despite anticoagulation, thrombi developed around the device and the valve was replaced at eight-months. The Mitra-SpacerTM successfully bridged this patient to surgery after LVEF had recovered.

WHAT IS KNOWN AND OBJECTIVE: Anticoagulation therapy with warfarin requires periodic monitoring of prothrombin time-international normalized ratio (PT-INR) and adequate dose adjustments based on the data to minimize the risk of bleeding and thromboembolic events. In our hospital, we have developed protocol-based pharmaceutical care, which we called protocol-based pharmacotherapy management (PBPM), for warfarin therapy. The protocol requires pharmacists to manage timing of blood sampling for measuring PT-INR and warfarin dosage determination based on an algorithm...

OBJECTIVE: Although the Cox-maze operation is the standard surgical procedure for permanent atrial fibrillation(AF), conversion to sinus rhythm is limited by patient characteristics, including the duration of AF, atrial size, and voltage of fibrillation waves. A surgical strategy based on structural alteration of the electrical substrates of AF is required to achieve better outcomes of AF surgery. Complex fractionated atrial electrogram (CFAE) plays an important role in the electrical substrate of AF...

OBJECTIVE: Myocardial protection is the most important in cardiac surgery. We compared our modified single-dose long-acting lignocaine-based blood cardioplegia with short-acting St Thomas 1 blood cardioplegia in patients undergoing single valve replacement. METHODS: A total of 110 patients who underwent single (aortic or mitral) valve replacement surgery were enrolled. Patients were divided in two groups based on the cardioplegia solution used. In group 1 (56 patients), long-acting lignocaine based-blood cardioplegia solution was administered as a single dose while in group 2 (54 patients), standard St Thomas IB (short-acting blood-based cardioplegia solution) was administered and repeated every 20 minutes...

von Willebrand Factor (vWF) is a well-known mediator of hemostasis and vascular inflammation. Its dynamic modulation in the bloodstream, according to hemodynamic conditions, makes it an appealing biomarker in patients with valvular heart disease (VHD). Recent studies highlight the close connection between vWF and VHD, with possible implications in the pathogenesis of VHD, promoting valve aging and calcification or favoring the development of infective endocarditis. Moreover, vWF has been recently proposed as a new diagnostic and prognostic tool in patients with valve stenosis or regurgitation, showing a strict correlation with severity of valve disease, outcome, and bleeding (Heyde syndrome)...

BACKGROUND: Nonbacterial thrombotic endocarditis is commonly seen on heart valves in patients with malignant or collagen diseases. The natural prognosis of nonbacterial thrombotic endocarditis is reported to be poor due to underlying malignancy. Surgical indications and appropriate timing for surgery for nonbacterial thrombotic endocarditis and underlying malignancy have not been formally studied. CASE PRESENTATION: The case was a 45-year-old woman who presented with a history of systemic embolization associated with occult malignancy...
