Libman-Sacks endocarditis is a cardiac manifestation of systemic lupus erythematosus (SLE) and antiphospholipid syndrome. We report a case of mitral valve destruction due to Libman-Sacks endocarditis, which was caused by activation of SLE, despite prompt initiation of systemic steroid therapy. The prevention of SLE activation is critically important in valve surgery for patients with SLE. To the best of our knowledge, this is the first case of repaired mitral valve destruction due to activation of SLE, which was caused by valve surgery itself...

Several reports have described that the prognosis of patients with mitral valve regurgitation due to active infective endocarditis (IE) is better after mitral valve plasty (MVP) than replacement (MVR). However, extensive destruction of valve tissue might cause difficulties with MVP. We repaired a widely-affected anterior mitral leaflet (AML) using an autologous pericardial patch. A 44-year-old woman with mitral regurgitation presented with prolonged fever and backache. We made a diagnosis of active IE accompanied by mitral valve regurgitation...

A 75-year-old woman with severe mitral regurgitation (MR) successfully underwent mitral valve plasty with edge-to-edge plasty and commissural annuloplasty. Three days after the operation, she was found to have moderate MR caused by tethering of the valve. Functional MR occurring as a complication of mitral edge-to-edge plasty could be treated conservatively.

Left ventricular noncompaction (LVNC) is believed to represent an arrest in the normal process of myocardial compaction, resulting in persistence of both hyper-trabeculation and intra-trabecular recess within the left ventricle. The clinical features of this disease are left ventricular dilatation and systolic dysfunction, which carry a high mortality. Most patients die in infancy, but some cases of LVNC in adults have been reported. To the best of our knowledge, only 4 cases of LVNC with valvular heart disease in adults have recently been operated...

OBJECTIVES: To determine a clinical standard for post-repair common atrioventricular valve orifice area based on mid- to long-term valve function in patients with a functional single ventricle. METHODS: The medical records of 19 single-ventricle patients who underwent common atrioventricular valve plasty from July 1988 to January 2013 were retrospectively reviewed. Bivalvation valvuloplasty was performed in 7 patients with relatively hypoplastic leaflets. The relationship between the orifice area of the repaired common atrioventricular valve measured intraoperatively and valve function and ventricular volume in the early postoperative period (median, 9...

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...

We report a rare case of aneurysmal formation of the left brachial artery complicated with infective endocarditis of the mitral valve. A 67-year-old man was referred to our institution for further examination of pulsatile mass at the left upper extremity. Computed tomography showed a left brachial arterial aneurysm with a diameter of 4 cm and gradual expansion of the aneurysm was also recognized. Furthermore, echocardiography revealed severe mitral valve regurgitation with a vegetation. There was no feature of congestive heart failure...

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...

Gilbert's syndrome (GS) is an autosomal inherited disorder characterized by relative deficiency of glucuronyl transferase and poor uptake of unconjugated bilirubin by hepatocytes. Cardiac surgery on cardiopulmonary bypass (CPB) in these patients triggers further hepatic dysfunction. Transesophageal echocardiography (TEE) and Doppler assessment of hepatic vein help in assessing hepatic blood flow (HBF) during cardiac surgery. Here, we discuss anesthetic management and role of TEE in maintaining HBF perioperatively in a 25-year-old male patient with GS undergoing double valve replacement with tricuspid valve plasty...

Treatment of ischemic mitral incompetence (IMI) is an important problem in cardiovascular surgery, and it is arguing to the best strategies for surgical treatment of IMI. IMI can be quantitative assessment precisely by three-dimensional ultrasonic sound. Perioperative transesophageal echocardiography can acquire detailed information about IMI, but it is possible to underestimate the degree of IMI. The effective mitral regurgitation area at resting are the independently prognosis factor in patients with IMI...

Here we report the early outcome of mitral valve replacement using a newly designed stentless mitral valve for failure of initial mitral valve repair. Mitral valve plasty (MVP) for mitral regurgitation is currently a standard technique performed worldwide. However, whether mitral valve repair should be performed for patients with advanced leaflet damage or complicated pathology remains controversial. Mitral valve replacement might be feasible for patients who have undergone failed initial MVP; however, it is not an optimal treatment because of poor valve durability and the need for anticoagulative therapy...

Letter to the Editor We read with great interest the report by Inoue et al. (Cusp-level chordal shortening for non-rheumatic mitralanterior leaflet prolapse in a patient with persistent atrial fibrillation. J Heart Valve Dis 2015;24:586-589) that described their mitral valve repair technique for anterior leaflet prolapse (ALP) and perioperative adaptive servo-ventilation (ASV) therapy for preventing the recurrence of atrial fibrillation after the maze procedure. Latent recurrence of atrial fibrillation after the maze procedure is caused by many factors...

A woman aged 36 years G2P1 presented at our outpatient clinic with symptoms of discomfort, dyspnoea and fever at a gestational age of 17 weeks. She was subsequently diagnosed with severe endocarditis with a large vegetation on the mitral valve. She underwent open chest mitral valve surgery while on cardiopulmonary bypass (CPB) within a few days. Such surgical intervention is not only associated with increased maternal risks, but also with severe fetal morbidity and mortality. In such patients, certain perioperative measures can diminish these risks...

BACKGROUND: Prominent mitral valve (MV) annular dilatation with only modest left ventricular (LV) dilatation in patients with MV prolapse (MVP) suggests predominant dilatation in adjacent basal LV, which may augment regional wall tension and attenuate contraction by Laplace's law. We hypothesized that MV annular dilatation in patients with MVP is associated with the basal predominance of LV dilatation and attenuated contraction, which can be altered by surgical MV plasty with annulus reduction...

We perform minimally invasive mitral valve plasty under totally endoscopic view. Skin incisions are composed of a 3 to 5 cm of main wound along the right 4th intercostal space, 1 trocar port in the 3rd intercostal space, and a camera port in the 5th intercostal space. Matal rib spreader is not used. A 3-dimensional endoscope was recently introduced. Forceps controlled by the left hand are inserted through the independent trocar port in the 3rd intercostal space. Left atrial retractor, aortic clamp, and all the cannulae are inserted through the main incision...

We performed coronary artery grafting, mitral valve plasty, and tricuspid plasty in a 75-year-old man who had double-vessel coronary disease and moderate mitral and tricuspid insufficiency. Preoperative transthoracic echocardiography revealed an ejection fraction of 34% and dyssynchronous wall motion of the septum and free wall. We placed pacing leads on the right ventricular outlet and posterior left ventricular wall for cardiac resynchronization therapy. The dyssynchrony disappeared postoperatively and the New York Heart Association functional class improved from IV to I...
