“…Some papers referred to the MDSAP in terminology associated with research, such as the “Canadian special access trial” and “Canadian special access study” ( Del Valle-Fernández et al 2010 ; Hancock-Howard et al 2013 ). Other research-oriented articles noted that the device was initially obtained via special access, and then became licensed.…”

New health technologies enter Canadian healthcare organizations in various ways, and understanding them is essential to the development of a pan-Canadian Health Technology Management (HTM) Strategy, now a priority of governments across Canada. One way is through Health Canada's Medical Devices Special Access Program (MDSAP), which permits unlicensed devices to be obtained by healthcare professionals. However, the circumstances around and implications of the current use of this program are not clear. A scoping literature review was conducted to clarify these and identify important roles and issues related to the MDSAP. Limited information was found on the MDSAP. Nevertheless, three themes demonstrating the roles of the MDSAP in HTM emerged: arbiter in technology selection, a route to technology procurement and facilitator of health technology innovation. No information suggesting that MDSAP is used to circumvent licensing was found. Rather, it enables desired patient outcomes and product commercialization.

“…In such cases, a transapical approach can be considered, hereby access to the left ventricle is achieved through a minithoracotomy with needle puncture, which is a viable alternative for patients who also have advanced peripheral vascular disease, but might be contraindicated in patients with lung disease, pericardial calcifications, extensive epicardial fat, previous left ventricular surgery and dysmorphic chest anatomy (19,21). This TAVI approach may become an attractive alternative in the future, especially if the incidence of cerebrovascular accidents is significantly smaller compared to the retrograde approach.…”

Another valuable alternative in patients with unsuitable femoral access includes the subclavian approach with high success rates showed by several small studies (21).…”

Since its introduction in 2002, transcatheter aortic valve implantation (TAVI) has assumed growing importance in the treatment of patients with severe aortic stenosis (AS), because it offers a much less invasive alternative for those in high risk for surgery. Good early results and advances in percutaneous valve technology have led to a substantial increase in procedural success rate and number of patients undergoing this less invasive treatment. Pre-procedural screening of several anatomic factors to assess the feasibility of this technique is important. Multidetector row computed tomography (MDCT) is the technique of choice in assessing these factors. This technical note aims to describe and illustrate the key elements that need to be evaluated before the procedure. Key-word: Aortic valve.From: 1.

“…Pole katetrizačních intervencí aortální chlopně se velmi rychle rozvíjí a lze očekávat zmenšení průměru chlopní, možnost jejich repozice in vivo a další technická vylepšení. 11 Domníváme se, že opatrný a konzervativní přístup k TAVI je nutný do potvrzení role této metody v delším sledování a nejlépe v randomizovaném srovnání s AVR. Za této podmínky lze v budoucnosti očekávat méně selektovanou aplikaci této metody.…”

Kočka V, Widimský P, Toušek P, et al. Katetrizační implantace aortální chlopně (TAVI) typu CoreValve -první zkušenosti ve FNKV, výhody a úskalí nové metody. Cor Vasa 2010;52(Suppl 1):70-75. Úvod: Aortální stenóza je nejčastější chlopenní vadou v dospělosti a katetrizační implantace aortální chlopně (TAVI) je novou, rozvíjející se alternativou ke standardní chirurgické náhradě aortální chlopně (AVR), vhodnou pro pacienty s vysokým operačním rizikem. Shrnujeme první zkušenosti s touto metodou na našem pracovišti. Metodika: Autoexpandibilní chlopeň CoreValve Revalving 18 F 3. generace je tvořena nitinolovým rámem a bioprotézou z prasečího perikardu. Přehledně popisujeme průběh výkonu. V období od dubna 2009 do ledna 2010 jsme TAVI provedli u 17 nemocných se symptomatickou významnou aortální stenózou. Stručná charakteristika souboru (průměrné hodnoty): věk 81 let, logistické EuroSCORE 21 %, plocha aortálního ústí 0,42 cm 2 /m 2 , ejekční frakce LK 52 %. Technická úspěšnost výkonu byla 100%. Mortalita do 30 dnů byla 0% a byl jasně patrný příznivý vliv TAVI na symptomatologii nemocných -dušnost se zlepšila alespoň o jeden stupeň NYHA klasifi kace u všech nemocných. Závěr: Naše první zkušenosti s TAVI jsou velmi povzbudivé. Úspěch TAVI je podmíněn týmovým přístupem při předoperačním hodnocení, technicky precizním výkonem a pečlivou pooperační péčí. Domníváme se, že opatrný přístup k indikaci TAVI je nutný do potvrzení role této metody v delším sledování, v budoucnosti lze očekávat méně selektovanou aplikaci této metody.

Transcatheter aortic valve implantation (TAVI) using the CoreValve prosthesis -initial experience in Královské Vinohrady University Hospital, advantages and pitfalls of the new method. Cor Vasa 2010;52(Suppl 1):70-75.Introduction: Aortic stenosis is the most common type of valvular heart disease in adulthood and transcatheter aortic valve implantation (TAVI) is a new, evolving alternative to standard surgical aortic valve replacement, suitable for high surgical risk patients. We present our initial experience with this method. Method: The third generation of a self expanding CoreValve Revalving 18 Fr. valve is made up of a nitinol frame and a bioprosthetic valve from the porcine pericardium. We describe the course of the procedure step by step. From April 2009 to January 2010, we performed the TAVI procedure in 17 patients with severe symptomatic aortic stenoses. Brief cohort characteristics are as follows (mean values): age 81 years, logistic EuroSCORE 21%, aortic valve area index 0.42 cm 2 /m 2 , left ventricular ejection fraction 52%. The procedural success rate was 100%. Thirty-day mortality was 0% and clinical improvement was obvious, with dyspnea improving by at least one NYHA class in all patients. Conclusion: Our initial experience with TAVI is most encouraging. Success of TAVI requires a team approach to preoperative assessment, a technically precise procedure and meticulous postoperat...
