Immediate and 3-Month Follow-Up Outcome After Cutting Balloon Angioplasty for Bifurcation Lesions

Balloon angioplasty of a bifurcation lesion is associated with lower rates of success and higher rates of complications than such treatment of lesions of most other morphologies. To date, the best device or procedure for bifurcation lesions has not been determined. The aim of this study was to compare the immediate and 3-month follow-up outcome of cutting balloon angioplasty (CBA) versus conventional balloon angioplasty (PTCA) for the treatment of bifurcation lesions. We treated 87 consecutive bifurcation lesions with CBA (n = 50) or PTCA (n = 37). Paired angiograms were analyzed by quantitative angiography, and angiographic follow-up was achieved for 93% of the lesions. The procedural success was 92% in the CBA group and 76% in the PTCA group (P < 0.05). Major in-hospital complications occurred in two lesions in the CBA group and six in the PTCA group (P = 0.05). The incidence of bail-out stenting in the CBA group was lower than in the conventional PTCA (8% vs 24%, P < 0.05). At the 3-month follow-up, the restenosis rate was 40% in the CBA group versus 67% in the PTCA group (P < 0.05). Clinical events during follow-up did not differ between the two groups. In conclusion, in comparison with PTCA, procedural success was greater and the restenosis rate lower with CBA. The results of this study support the use of the cutting balloon as optimal treatment for bifurcation lesions. (J Interven Cardiol 2004;17:1,7) [source]

Clinical and Angiographic Outcome after Cutting Balloon Angioplasty

The cutting balloon is a new device for coronary angioplasty, that, by the combination of incision and dilatation of the plaque, is believed to be promising for treatment of in-stent restenosis. The purpose of the study was to evaluate the safety and efficacy of CBA. We reviewed the immediate and 6-month follow-up angiographic and clinical outcome of 147 patients (109 men and 38 women) with a mean age of67.3 10undergoing this procedure at eight interventional centers in Austria. The target lesions treated with CBA were in-stent restenosis in 61% of patients, stenosis after balloon angioplasty in 8% of patients, and native lesions in 33% of patients. Sixty-five percent of the patients included had multivessel disease. Lesion type was A in 18% of patients, B1 in 31% of patients, B2 in 39% of patients, and C in 12% of patients. The degree of stenosis was87% 9%,the length of the target lesion treated with CBA was8.8 5.1 mm. Target vessel was left circumflex artery in 22 cases, right coronary artery in 36 cases, and left anterior descending artery in 89 cases. The overall procedural success rate was 90.5%. "Stand-alone" CBA was performed in 63% of patients, the procedure was combined with coronary stenting in 16% of patients, and with balloon angioplasty in 21% of patients. Coronary complications occurred in eight cases (5.4%) with coronary dissection in seven (total dissection rate of 4.7%) and urgent bypass surgery in one case (0.7%). No further complications such as death, occlusion, or perforation of coronary arteries, embolization, or thrombosis were observed. Six-month clinical follow-up revealed q-wave myocardial infarction in 2.7% of patients, aortocoronary bypass surgery in 8.5% of patients, and repeated percutaneous coronary intervention in 17% of patients (11.5% with stenting). Six-month angiographic follow-up of patients with recurrent angina showed target lesion restenosis (>50% diameter stenosis) in 14% of patients, late lumen loss with ,50% diameter stenosis in 6% of patients and progression of "other than target" lesions with >50% diameter stenosis in 14% of patients. This series demonstrates the safety and feasibility of cutting balloon angioplasty in patients with complex coronary artery disease and in-stent restenosis.

Cutting Balloon Angioplasty for Ostial Lesions of the Left Anterior Descending Artery

We evaluated the effectiveness of Cutting Balloon angioplasty for ostial lesions of the left anterior descending artery compared with conventional balloon angioplasty. Cutting Balloon angioplasty (n = 7) produced larger acute gain (1.70 0.37 vs 0.48 0.25 mm, P < 0.001) and smaller late loss index (0.54 0.55 vs 1.32 0.81, P < 0.05) than conventional balloon angioplasty (n = 7). As a result, late restenosis was seen in only two patients undergoing Cutting Balloon angioplasty, but in all seven patients undergoing conventional balloon angioplasty. Ostial lesions of the left anterior descending artery may be one of the suitable targets of Cutting Balloon angioplasty. (J Interven Cardiol 2000;13:7,14) [source]

Transradial intervention for native fistula failure

Osami Kawarada MD
Abstract The native radiocephalic (Brescia-Cimino) fistula is usually constructed with an anastomosis of the cephalic vein and radial artery. Catheter interventions for native fistula failure have until now been performed via the transcephalic or transbrachial approach. Transradial intervention for native fistula failure was prospectively evaluated for a selected consecutive 11 patients. Six patients had a single lesion and 5 patients had double lesions. Twelve lesions were stenotic and 4 were occlusive with thrombus. Balloon angioplasty alone was successful in 10 lesions. In thrombosed fistulas, 2 lesions underwent manual catheter-directed thrombo-aspiration and 2 further lesions underwent a combination of catheter-directed thrombo-aspiration and mechanical thrombectomy. Cutting Balloon angioplasty was performed for 3 resistant venous stenoses and for 1 radial artery stenosis. Technical and clinical success were achieved in all patients. No vessel rupture or perforation was observed in this study, nor was distal embolization in the radial artery or symptomatic pulmonary embolism. No radial artery occlusion or fistula infection was seen during the follow-up. The primary patency rates were 82% at 3 months and 64% at 6 months. Transradial intervention for native fistula failure is considered safe and feasible in a selected population; yet requires further validation. 2006 Wiley-Liss., Inc. [source]
