Hemolysis after percutaneous device closure of ventricular septal defect (VSD) is a rare complication that can be conservatively managed in the majority of cases. However, surgery or transcatheter occlusion may be necessary. Presently described is the successful treatment of hemolysis that developed after implantation of the Nit-Occlud Lê VSD coil, using the Amplatzer Duct Occluder II (ADO II) in a patient with aneurysmatic perimembranous VSD. Systolic murmur and symptoms immediately disappeared after the procedure...

BACKGROUND: Severe inotrope-dependent acute heart failure (AHF) is associated with poor clinical outcomes. There are currently no well-defined blood biomarkers of response to treatment that can guide management or identify recovery in this patient population. In the present study, we characterized the levels of novel and emerging circulating biomarkers of heart failure in patients with AHF over the first 30 days of medical management or mechanical circulatory support (MCS). We hypothesized a shared a plasma proteomic treatment response would be identifiable in both patient groups, representing reversal of the AHF phenotype...

Transcatheter aortic valve implantation (TAVI) has revolutionized the management of elderly patients with symptomatic severe aortic stenosis in the western world. It is a valuable alternative to surgical aortic valve replacement in patients, who are inoperable or at high surgical risk due to co-morbidities. The prevalence of aortic stenosis increases sharply with age after the sixth decade and is expected to have a significant impact on the geriatric health care system of India, given the rapid increase in life expectancy in recent years...

BACKGROUND: Silent sinus or imploding antrum syndrome is a very rare condition, consisting of a usually asymptomatic spontaneous collapse of the sinus walls and floor of the orbit. It is associated with negative pressures, and when this occurs, it presents with manifestations such as enophthalmos, hypoglobus, and tilt flow orbital floor. As its incidence is very low, it is frequently missed as a diagnosis, and in fact there are currently fewer than 150 cases reported in the literature...

Management of dialysis patients with valvular heart disease waitlisted for kidney transplantation is challenging. Development of severe aortic valve stenosis can lead to the exclusion from the transplant program or even death while on the waiting list. In dialysis patients, surgical aortic valve replacement is associated with a high perioperative risk with increased morbidity and mortality. In contrast, transcatheter aortic valve implantation emerges as a viable option for dialysis patients. Herein, we present the long-term follow-up of successful kidney transplantation after TAVI in a diabetic patient receiving long-term hemodialysis...

Periprosthetic humerus fractures are relatively uncommon occurrence that can be difficult to manage nonoperatively. Locking plate technology has enhanced the surgical management of these fractures. However, adequate fixation around the stem remains of some concern. We describe an osteosynthesis technique using a locking plate utilizing eccentrically placed screw holes to place "skive screws" in the proximal end of the plate to achieve fixation around the stem of the implant. A clinical series of 5 consecutive patients treated with this technique is presented with an average follow-up of 29 months (range, 12-48)...

INTRODUCTION: One-stage implant-based breast reconstruction using titanium-coated polypropylene mesh is a novel approach widely used in Europe. Complication rates in breast reconstruction with the use of titanium-coated meshes seem to be comparable to those in patients with implant-based breast reconstruction alone. However, the use of synthetic meshes in implant-based breast reconstructive surgery leads to new clinical scenarios with the need for the breast surgeon to face new complications...
