BACKGROUND: Minimally invasive aortic valve replacement (MAVR) has demonstrated a benefit with respect to increased patient satisfaction due to minimised pain and earlier recovery. Sutureless valves may benefit MAVR and conventional aortic valve replacement (AVR) by reducing operative times and blood transfusion requirements. The Perceval valve (Sorin, Salluggia, Italy) is a self-expanding prosthesis made from bovine pericardium mounted in a nitinol stent, designed to simplify the implantation of an aortic valve...

OBJECTIVES: Combined coronary artery bypass grafting and valve surgery requires a prolonged period of cardioplegic arrest (CA) predisposing to myocardial injury and postoperative cardiac-specific complications. The aim of this trial was to reduce the CA time in patients undergoing combined coronary artery bypass grafting and valve surgery and assess if this was associated with less myocardial injury and related complications. METHODS: Participants were randomized to (i) coronary artery bypass grafting performed on the beating heart with cardiopulmonary bypass support followed by CA for the valve procedure (hybrid) or (ii) both procedures under CA (conventional)...

We present a rare case of mitral regurgitation with anterior mitral leaflet perforation associated with gelatin-resorcinol-formaldehyde (GRF) glue. We performed mitral valve replacement for anterior mitral leaflet perforation occurred 7 years after aortic valve replacement and abscess cavity repair using GRF glue. Long-term follow-up is needed for patients who have undergone surgeries using GRF glue or BioGlue (CryoLife, Inc, Kennesaw, GA) because of the possibility of late complications. In particular, when an eccentric mitral regurgitation is observed after aortic root surgery using GRF glue or BioGlue, anterior mitral leaflet perforation should be considered...

Scientific progress shall ultimately boost the current acceptance level for conservative aortic valve surgery. The present text aimed to report the 23-year long-term follow-up of one patient operated with bovine pericardium cusp extension. Growing confidence in the efficacy of the operation will allow a more expeditious indication for surgical treatment, as is already the case in mitral valve repair. This change of attitude will certainly make it possible for patients to be sent for operation in mild aortic valve regurgitation...

INTRODUCTION: Nonocclusive mesenteric ischemia (NOMI) after surgery has an extremely poor prognosis with a mortality rate of 30-100%. We report a patient with NOMI following aortic valve replacement who failed to improve despite continuous intra-arterial infusion of papaverine, but was successfully treated with alprostadil (prostaglandin E1 [PGE1]) infusion. PRESENTATION OF CASE: The patient is a 77-year-old man who underwent aortic valve replacement. Due to elevated serum lactate levels five hours after intensive care unit admission, superior mesenteric arteriography was performed, establishing the diagnosis of NOMI...

INTRODUCTION: Pyomyositis has traditionally been considered a tropical disease. Increasing prevalence has been observed in more northern climates, especially with HIV, immunosuppression, and IV drug abuse as predisposing factors. Pyomyositis has the tendency to mimic other conditions, such as muscle contusion, necrotizing fasciitis, or septic arthritis. The rarity of this disease and non-specificity of its symptoms often lead to delay in appropriate diagnosis and treatment. CASE: 24-year-old man, seen 2 days prior in orthopedics clinic and the Emergency Department for persistent gluteal pain thought to be due to right-sided sciatica, was admitted following worsening pain, diffuse generalized weakness with polyarthralgias and myalgias These symptoms were associated with night sweats, shaking chills, and difficulty walking...

BACKGROUND: Bundled Payments for Care Improvement (BPCI) initiatives were developed by Medicare in an effort to reduce expenditures while preserving quality of care. Payment model 2 reimburses based on a target price for 90-day episode of care postprocedure. The challenge for valve patients is the historically high (>35%) 90-day readmission rate. We analyzed our institutional cardiac surgical service line adaptation to this initiative. METHODS: On May 1, 2015, we instituted a readmission reduction initiative (RRI) that included presurgical risk stratification, comprehensive predischarge planning, and standardized postdischarge management led by cardiac nurse practitioners (CNPs) who attempt to guide any postdischarge encounters (PDEs)...
