Transapical transcatheter aortic valve replacement with the balloon expandable aortic bioprosthetic valve in high risk patients with severe aortic stenosis: Intermediate-term results from the register of the clinic of cardiac surgery.

BACKGROUND: The purpose of this study is to report our experience in performing transapical (TA) TAVR with a balloon-expandable valve only by cardiac surgeons, with on site interventional cardiology support. METHODS: A retrospective review of 97 consecutive patients that underwent TA TAVR due to severe symptomatic aortic stenosis was performed from 2012 to 2016. Median follow-up time was 20.5 months. Preoperative risk factors and postoperative outcomes were evaluated using Valve Academic Research Consortium-2 definitions. RESULTS: All patients were high risk with a mean Euroscore of 7.28±7.77. Five year and 30-day mortality were 9.3 % and 1.1 %, respectively. Ninty six (98.9 %) of the patients had no or mild paravalvular leak seen by transesophageal echocardiography after implantation. Device success was 91.8%. Postoperatively there was a significant increase of the ejection fraction (50.8±7.1 % preoperatively vs 53.1±7.7 % postoperatively, p=0.009) and reverse remodeling of the left ventricle (left ventricular end-diastolic diameter preoperatively 50.8±7.1 mm vs 49.2±8.1 mm postoperatively, p=0.031). CONCLUSION: Our experience demonstrates that TA TAVR can be performed only by cardiac surgeons, with on site interventional cardiology support safely and successfully with low and comparable postoperative mortality and rate of complications (Tab. 4, Fig. 1, Ref. 26).

Socio-environmental profile of child and adolescents sensitized by house dust mite in northeast of Brazil.

INTRODUCTION: The association regarding the atopic sensitization to mite aeroallergens and the socio-environmental features is still inconsistent. OBJECTIVES: We analyzed the role played by socioeconomic and environmental factors in the prevalence of sensitization to house dust mite (HDM) allergens, and associated with the risk of developing asthma symptoms. PATIENTS AND METHODS: This is a case-control study conducted with 108 patients, aged 1-17. We inquired about family habits, socioeconomic and environmental features. We applied the International Study of Asthma and Allergies in Childhood questionnaire. RESULTS: We observed patients sensitized to all HDM tested, Derp (42%), Derf (37%) and Blot (33%). Middle family income (OR: 2.74; CI95%: 1.127-6.684), exposure to dog (OR: 3.758, CI95%: 1.127-6.684) and artificial climatization (OR: 4.319, CI95%: 1.398-13.348) were associated with sensitization to Derp. We also observed protective factors, such as sharing of dormitories, washing cycle for bedspreads and the presence of basic sanitation. An increased risk of sensitization to Derf was associated with Blot sensitization (OR: 3.172, CI95%: 1.083-9.292) and presence of mold on the walls (OR: 3.095, CI95%: 1.063-9.008). A protective factor was dormitory sharing. For sensitization to Blot, we observed an increase in the risk associated with Derp sensitization (OR: 3.462, CI95%: 1.191-10.061) and exposure to dog (OR: 3.255, CI95%: 0.987-10.736). In addition, sensitization to Blot increases the risk of developing asthma symptoms (OR: 2.732, CI95%: 0.981-7.606). CONCLUSION: Our data show distinct sociodemographic and environmental relations that lead to HDM sensitization and increased probability of development of allergic diseases.

[Recurrent prosthetic endocarditis in a 21-year old patient with renal transplantation treated with allogeneic homograft]. / Recidivujúca protetická endokarditída u 21-rocného pacienta s transplantovanou oblickou riesená alogénnym homograftom.

Prosthetic infective endocarditis is a possible complication of implantation of a prosthetic cardiac valve. Without early and effective treatment, it can have fatal consequences. One treatment option is use of an allogeneic cryopreserved homograft. This case report presents a 21-year old patient after kidney transplantation due to hereditary nephrotic syndrome and aortic valve replacement with aortic conduits. After fever was noted in the patient, prosthetic infective endocarditis was diagnosed by echocardiography and also confirmed by CT-3D examination. The cryopreserved aortic homograft was implanted at the Department of Cardiac Surgery. This along with additional conservative management effectively treated the infection. Based on literature data and our own experience, we believe that the treatment of prosthetic endocarditis after aortic valve replacement with cryopreserved homograft can be a method of choice.

[Septic shock due to infective endocarditis of stimulation system of implantable cardioverter-defibrillator]. / Septický sok v dôsledku infekcnej endokarditídy stimulacného systému implantabilného kardioverter defibrilátora.

We present a case of a 60-year old patient hospitalized at the Department of Infectious Diseases and Travel Medicine, Medical faculty of UPJS and L. Pasteurs University Hospital in Kosice with suspected gastroenteritis. The patient was admitted to an intensive care unit because of the signs of septic shock. Within one hour from admission, the patient was administered early goal directed therapy for septic shock. Subsequently, infectious endocarditis of stimulation electrodes and tricuspid valve was identified as the origin of the infection. The stimulation system was then explanted from a stabilized and afebrile patient at the Department of cardiac Surgery of Eastern Slovak Institute of Cardiac and Vascular Diseases in Kosice. This case should emphasise frequently atypical course of this serious disease and the need for early identification of severe sepsis to enable timely management to affect mortality.
