OBJECTIVES: With the emergence of transcatheter mitral valve-in-valve/ring replacement for deteriorated bioprostheses or failed repair, comparative clinical benchmarks for surgical repeat mitral valve replacement (re-MVR) are needed. We present in-hospital and survival outcomes of a 24-year experience with re-MVR. METHODS: From January 1992 to June 2015, 520 adult patients underwent re-MVR; 273 had undergone prior mitral valve repair (pMVP) and 247 had undergone prior MVR (pMVR)...

BACKGROUND & AIMS: Little is known about the effects of antiviral therapy on short- and long-term survival of patients with hepatitis B virus (HBV)-related decompensated cirrhosis. We aimed to determine whether a maintained virologic response (MVR, defined as persistent undetectable HBV DNA during therapy) associates with short-term (6-month) and long-term (6-120 months) survival of patients with decompensated cirrhosis. METHODS: We performed a 10-year observation analysis using data from the Epidemiology and Natural History of Liver Cirrhosis study of patients with decompensated liver cirrhosis in Korea...

BACKGROUND: For pancreatic tumors located in the body or tail of the pancreas, distal pancreatectomy (DP) remains the surgical procedure of choice to achieve radical tumor removal. Purpose of this study was to evaluate outcome and overall survival of patients who underwent DP combined with multivisceral resection (MVR). METHODS: Retrospective single-center case-matched analysis. Between January 1994 and June 2014, 494 consecutive patients were entered into a prospective database, and 126 patients undergoing DP + MVR (cases) were matched with 126 patients undergoing DP (controls) for gender, age, and underlying final diagnosis...

BACKGROUND: With the newly described one step melanoma surgical approach, some patient groups could be successfully treated within one surgical session. Depending on the tumour thickness (measured preoperatively) at a later stage (also depending on the ultrasound findings of the locoregional lymph nodes) the respective surgical intervention is planned with the respective field of surgical safety (one-stage melanoma surgery with or without removal of lymph nodes). The innovations could make to some extent some of the already existing algorithms more difficult (due to the introduction of a high-frequency ultrasound to determine the tumor thickness preoperatively as an absolute prerequisite for dermosurgical centres), but it would also lead with absolute certainty to better or least optimal results regarding the prognosis, the side effects and the financial factor also...

OBJECTIVES: Minimally invasive mitral valve surgery (mini-MVR) has numerous associated benefits. However, many studies fail to include greater-risk patients. We hypothesized that a minimally invasive approach in a representative cohort provides excellent outcomes with reduced resource utilization. METHODS: Mitral valve surgical records from 2011 to 2016 were paired with institutional financial records. Patients were stratified by approach and propensity-score matched to balance preoperative difference...

Based on the hierarchical equations of motion approach, we study the time-dependent transport properties of a strongly correlated quantum dot system in the Kondo regime (KR), mixed valence regime (MVR), and empty orbital regime (EOR). We find that the transient current in KR shows the strongest nonlinear response and the most distinct oscillation behaviors. Both behaviors become weaker in MVR and diminish in EOR. To understand the physical insight, we examine also the corresponding dot occupancies and the spectral functions, with their dependence on the Coulomb interaction, temperature, and applied step bias voltage...

OBJECTIVES: Favourable outcomes with mitral annuloplasty have been achieved with transapical cardioscopic (TAC) surgery in a survival animal model. In addition, experimental TAC on a non-survival animal model also showed adequate access to remove the native mitral valve and implant a prosthetic valve, but the surgical procedure took a long time and lacked follow-up data. The goal of this study was to develop a clinically translatable TAC mitral valve replacement (MVR) procedure using technical and instrumental refinements to reduce the surgical time and to evaluate functional recovery and short-term durability using a survival porcine model...
