    Coronary artery aneurysm is a rare congenital or acquired anomaly. The commonest location of coronary artery aneurysms is the right coronary artery and they are found slightly more often in males. We report an unusual case of multiple and extremely large aneurysms, therefore potentially at risk of rupture or thrombosis. (Cardiol J 2011; 18, 4: 434–436

    Sinus of Valsalva aneurysm

    Bicuspid aortic valve is one of the most common congenital cardiac anomalies and it may be accompanied by other cardiovascular anomalies. Sinus of Valsalva aneurysm is a rare anomaly in adult population, but it coexists with bicuspid aortic valve quite often. This report describes a 57 years-old patient who had a bicuspid aortic valve accompanied by unruptured Valsalva sinus aneurysm with significant left anterior narrowing and who underwent successful surgery with ascending aorta and aortic valve replacement as well as coronary by-pass grafting

    Introduction: In-stent restenosis still remains a serious clinical problem. Local intramural drug delivery (LDD – Local Drug Delivery) seems to be an interesting alternative to drug-eluting stents (DES). Aim: The aim of the study was to assess the safety and effectiveness of local intramural paclitaxel administration in the treatment of recurrent in-stent restenosis (ISR). Methods: Five patients were enrolled in the study (3 men, mean age 50±7 years) with at least a second episode of ISR within the same stent. Percutaneous coronary angioplasty was performed on a total of 11 vessel segments. Remedy delivery catheters (Boston Scientific) were used for balloon angioplasty. Inflation pressure was calibrated to obtain a balloon/vessel lumen ratio of 1.1:1. Then the pressure was lowered to 3 atmospheres and 100 µg of paclitaxel diluted in 2 ml of 0.9% NaCl was given over 60 seconds under the pressure of 2-3 atmospheres. This dose was used for each 10 mm of lesions. Control coronary angiography was performed six months after the procedure. Results: In all patients effective target vessel revascularisation was achieved. No adverse events were observed in the periprocedural period or during the 6-month follow-up period. Control angiography revealed ISR in three segments (27.2%) and in-stent late lumen loss of 0.21±0.93 mm. Conclusions: Local intramural paclitaxel delivery is a safe and effective method of ISR treatment. The optimal paclitaxel dose should be established in further studies.Restenoza w stencie pozostaje nadal powa偶nym problemem klinicznym. Miejscowe, 艣r贸d艣cienne podawanie lek贸w cytotoksycznych (Local Drug Delivery, LDD) mo偶e stanowi膰 interesuj膮c膮 alternatywn膮 metod臋 w stosunku do stosowania stent贸w typu DES. Cel: Celem badania by艂a ocena bezpiecze艅stwa i skuteczno艣ci 艣r贸d艣ciennego, miejscowego podawania paklitakselu w leczeniu nawrotowej restenozy w stencie (ISR). Metoda: Do badania w艂膮czono 5 chorych (3 m臋偶czyzn, 艣redni wiek 50±7 lat), z co najmniej drugim epizodem ISR w obr臋bie tego samego stentu. Zabiegom PTCA poddano 艂膮cznie 11 segment贸w naczyniowych. Do angioplastyki balonowej u偶yto cewnik贸w transportowych Remedy (Boston Scientific). Ci艣nienie inflacji dobierano tak, aby uzyska膰 stosunek 艣rednicy balon/naczynie 1.1:1. Nast臋pnie zmniejszano ci艣nienie do 3 atm. i przez oko艂o 60 s podawano 100 µg paklitakselu rozpuszczonego w 2 ml 0,9% NaCl pod ci艣nieniem 2–3 atm. Powy偶sz膮 dawk臋 stosowano na ka偶de 10 mm d艂ugo艣ci docelowej zmiany. Kontrolne badanie angiograficznie wykonano po up艂ywie 6 miesi臋cy u wszystkich chorych. Wyniki: U wszystkich chorych uzyskano skuteczne poszerzenia zmian docelowych. W okresie oko艂ozabiegowym oraz podczas 6-mies. okresu obserwacji nie zanotowano zdarze艅 niepo偶膮danych. Kontrolna koronarografia ujawni艂a ISR w trzech segmentach (27,2%) oraz 艣redni膮 p贸藕n膮 utrat臋 艣wiat艂a w obr臋bie stentu 0,21±0,93 mm. Wnioski: Zabiegi LDD z u偶yciem paklitakselu s膮 bezpieczn膮 i skuteczn膮 metod膮 leczenia ISR. Ostateczna wielko艣膰 dawki paklitakselu powinna by膰 okre艣lona w nast臋pnych badaniach
