RESUMO

AIM: The Crown PRT (The Phospholipid Reduction Treatment) is a new stent bovine bioprosthesis for aortic valve replacement (AVR). Aim of this paper is to report the postoperative clinical and hemodynamic results after ninety consecutive implants. METHODS: After receiving CE mark in July 2014, two European university centers implanted the new Crown PRT (Sorin Group, Burnaby, Canada) for the first time. Up to now, ninety patients underwent aortic valve replacement, in isolated or combined procedures, for aortic stenosis or insufficiency. Intraoperative transesophageal echocardiogram was used to assess the prosthesis's function. In hospital outcomes and echocardiographic parameters were recorded. RESULTS: Age and Log Euroscore were 71.8±7.9 years and 10.2%±4.5 respectively. In-hospital mortality for isolated AVR was 0%; one patient died after a multiple procedure (overall 30-days mortality 1.1%). No adverse device effects were recorded. Intensive Care Unit stay was 2±5.8 days. At discharge, echocardiogram showed no paravalvular leaks and normal postoperative gradients. CONCLUSION: Our starting results showed that the Crown PRT is safe and reliable, with excellent hemodynamic performance. Further clinical results with a larger population and long term follow-up are needed to assess the versatility and the durability of this new device.

RESUMO

Dengue virus (DENV) is an arthropod-borne virus (family Flaviviridae) causing dengue fever or dengue hemorrhagic fever. Here, we report the first fatal DENV infection imported into Germany. A female traveler was hospitalized with fever and abdominal pain after returning from Ecuador. Due to a suspected acute acalculous cholecystitis, cholecystectomy was performed. After cholecystectomy, severe spontaneous bleeding from the abdominal wound occurred and the patient died. Postmortem analysis of transudate and tissue demonstrated a DENV secondary infection of the patient and a gallbladder wall thickening (GBWT) due to an extensive edema.
