Depending from the etiology of mitral valve pathology and surgical risk, mitral valve surgery is the therapy of choice for most degenerative mitral valve diseases. In isolated secondary mitral valve regurgitation, the indication for interventional or conservative therapy becomes more important. In severe left ventricular dysfunction heart transplantation has to be taken into consideration. If relevant coronary artery disease is present and bypass surgery is indicated, mitral valve surgery is mandatory in severe regurgitation and is subject to a benefit-risk evaluation in moderate regurgitation...

BACKGROUND: So far, the specific appearance of QRS complex, ST-segment, and T wave was observed in aortic stenosis (AS). S-wave dynamic change in leads V1 -V3 was not reported in AS. METHODS: In a single-center, prospective study, we included a total number of 1.175 patients who underwent surgical aortic valve replacement (AVR). We conducted 3-year gathering of patients with symptomatic and asymptomatic severe AS, and separated them by hemodynamic stability into groups A and B, through EFLV (of more or less than 50%), AVA (of more or less than 0...

There continues to be a critical need for developing data-informed computational modeling techniques that enable systematic evaluations of mitral valve (MV) function. This is important for a better understanding of MV organ-level biomechanical performance, in vivo functional tissue stresses, and the biosynthetic responses of MV interstitial cells (MVICs) in the normal, pathophysiological, and surgically repaired states. In the present study, we utilized extant ovine MV population-averaged 3D fiducial marker data to quantify the MV anterior leaflet (MVAL) deformations in various kinematic states...

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...

Howard C Herrmann, Wilson Y Szeto, Harold Litt, William Vernick
Left ventricular outflow tract (LVOT) obstruction is a recognized complication of transcatheter mitral valve-in-valve replacement in previous surgical prostheses. We describe a patient who was high risk for repeat open surgery in whom the LVOT was compromised by a surgical strut and the potential for LVOT obstruction. A novel approach to avoiding this complication was utilized. A perfusion balloon was inflated in the outflow tract to provide an opposing force during mitral valve deployment resulting in less flaring of the strut into the outflow tract thereby improving the neo-LVOT area...

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...
