Retrieval of directional coronary atherectomy guiding catheter with angioplasty balloon catheter

Directional coronary atherectomy (DCA) has been shown to be a safe and effective treatment for occlusive coronary artery disease. We report a case of an atherectomy guiding catheter severing in two with successful retrieval of the dislodged segment by an integrated angioplasty balloon catheter system. © 1995 Wiley-Liss, Inc.     

Guide catheter exchange

The role of coronary vasoconstriction in acute myocardial infarction is controversial. Two patients are presented who were studied with angiography during the early hours of acute myocardial infarction and in whom reversible spasm of non-infarct vessels was observed. A tendency towards coronary vasospasm may be a generalized phenomenon during acute myocardial infarction. © 1995 Wiley-Liss, Inc.

Double loop guiding catheter: A primary catheter for angioplasty of the right coronary artery

Double loop guiding catheters have been used for percutaneous transluminal coronary angioplasty (PTCA) of the right coronary artery (RCA) in 42 consecutive cases. A catheter with a 90- degree primary curve was used when the proximal RCA had horizontal or inferior orientation. When the proximal segment of the RCA was oriented superiorly (shepherd's crook), the catheter with a 75-degree primary curve was used. Catheters were fabricated with short (1.5 cm) or long (2.3 cm) (USCI, C.R. Bard, Inc., Billerica, MA) distal tips. Short-tip catheters were satisfactory in the majority of cases. When the RCA had a complex course and more backup was necessary or when the ascending aorta was wide, long-tip catheters were found to be the best choice. Angioplasty of 49 lesions was attempted in 42 consecutive patients. In 39 patients successful dilatation was achieved (93%). In three patients the procedure was unsuccessful. In one patient, the lesion could not be crossed with the guidewire despite an excellent backup. In another patient, two of three stenoses were dilated successfully; the distal lesion was crossed with a guidewire but could not be crossed with the balloon catheter in spite of a good backup. The lack of a satisfactory engagement and inadequate backup were responsible for the failure in only one patient. There were no complications related to these guiding catheters. We conclude that double loop guiding catheters are safe and can be the primary choice in all right coronary angioplasties. These catheters provide an excellent backup with consequent high success rate.     

Coronary artery angioplasty with a helical autoperfusion balloon catheter

The initial in-hospital and long-term clinical experience with a helical autoperfusion balloon catheter in the treatment of coronary artery disease is reported. This new catheter design allows blood to flow passively around the inflated balloon through a protected helical channel molded into the balloon surface. Twelve consecutive patients underwent PTCA. Continuous ST monitoring, heart rate, average peak distal coronary blood flow velocity (APV), coronary blood flow (CBF), dP/dt and systemic and pulmonary arterial pressures were determined during PTCA. During balloon inflation there were no hemodynamic changes, TIMI flow was 1.7 ± 0.8, and APV was 39% of baseline. Luminal diameter stenosis improved from 61 ± 17 to 29 ± 13% (P < 0.05) following PTCA. Mean continuous inflation duration was 385 ± 215 sec and 6/12 patients had ≥ 7.5-min inflations. There were no in-hospital adverse cardiac events. One patient developed recurrent angina during 8 mo of follow-up and underwent successful PTCA of a restenotic lesion. We conclude that human plaques can be successfully dilated with a helical balloon catheter that provides autoperfusion and the ability to perform prolonged inflations with hemodynamic stability. A comparison of this PTCA catheter with standard balloon catheters is warranted. Cathet. Cardiovasc. Diagn. 40:179–185, 1997. © 1997 Wiley-Liss, Inc.     

Distal stent delivery with guideliner catheter: First in man experience

Failure to deliver stents is one of the commonest causes of procedural failure in contemporary PCI practice. We describe successful use of the Guideliner Catheter, the first purpose designed FDA and CE marked device delivery catheter in 13 complex cases in native coronary vessels and bypass grafts performed via the radial route to enable distal stent delivery following failure of conventional techniques. We discuss how the Guideliner catheter may be used to facilitate difficult radial cases. © 2010 Wiley‐Liss, Inc.     

Initial experience with a new balloon-on-a-wire catheter: The bijouTM

This paper presents our initial experience with a new low-profile balloon “on-a-wire” catheter, the Bijou. The concept of this balloon is to provide an additional side lumen with the advantages of (1) the ability to measure pressure gradient, (2) the possibility of drug infusion, and (3) the ability to advance a steerable guidewire through this side lumen. The balloon has been tested in 15 patients; 14 underwent an elective procedure for stable angina pectoris (with 2 cases of restenosis) and one an emergency angioplasty in a case of acute myocardial infarction. The stenosis was located on the left anterior descending artery in 11 procedures, on the right in 3, on a marginal branch in 2, on the circumflex and a saphenous vein graft in 1. All stenoses could be dilated successfully (residual stenosis <25%). The transstenotic pressure gradient felt from 49±13 mmHg to 7±4 mm Hg after angioplasty. Except for an uncomplicated dissection in 3 patients, no other complication was noted. With this new catheter, the double-lumen configuration adds the advantages of an “over-the-wire” to an “on-a-wire” system. © 1993 Wiley-Liss, Inc.     

Effective plaque removal with a new 8 French-compatible atherectomy catheter.

The purpose of this study was to evaluate the safety and efficacy of the new 8 Fr guide catheter-compatible Flexicut directional atherectomy device and to compare it with the conventional Atherocath GTO catheter. The 6 Fr Flexicut catheter has a larger cutting window and a titanium nitride-coated cutter to effect more tissue removal as well as treat mildly calcified lesions. A group of 143 lesions in 117 consecutive patients treated with the Flexicut catheter in four centers were compared with a control group of 277 lesions in 212 consecutive patients treated with the GTO device. Postatherectomy luminal diameters were larger (2.92 +/- 0.79 vs. 2.52 +/- 0.64 mm; P < 0.0001), with more luminal gain (relative gain: 0.58 +/- 0.24 vs. 0.48 +/- 0.25; P = 0.0007) using fewer directional coronary atherectomy (DCA) cuts (12 +/- 7 vs. 16 +/- 9; P = 0.0001) in the Flexicut group. A residual diameter stenosis < 20% immediately after DCA was obtained in 77% of the lesions in the Flexicut group vs. 45% in the GTO group (P < 0.0001). Histology in the former group revealed large calcium speckles in the retrieved specimens. In the Flexicut group, there was a lower incidence of access site complications and damage to the coronary ostium (2.5% vs. 7.5%; P = 0.08). The new Flexicut catheter is more effective than the conventional GTO catheter with a trend for reduced guiding catheter-related complications.     

Novel uses of the proxis embolic protection catheter

The Proxis catheter has been designed for proximal embolic protection during saphenous vein graft interventions. The Proxis catheter's flexible and kink‐resistant design, lubricity, and atraumatic tip allow deep seating in target vessels. We describe six challenging percutaneous coronary intervention cases, in which the Proxis catheter was used in arterial grafts, sequential saphenous vein grafts, and native coronary arteries. Deep seating of the Proxis catheter enabled vessel visualization and equipment delivery, allowing successful completion of each case. © 2009 Wiley‐Liss, Inc.
