RESUMEN

Coronary perforation during percutaneous coronary interventions is a rare but dreadful complication. While coronary perforation involving large vessels are managed successfully by covered stents, small distal vessel perforation is usually managed by prolonged balloon inflation or embolization of gel foam/thrombogenic metallic coils. We describe a case, where perforation of a small ventricular branch of the right coronary artery was successfully occluded by packing it with pieces of thrombogenic floppy tips of used coronary angioplasty guidewires instead of conventional metallic coils.

RESUMEN

We report an unusual complication of a 25 mm long stent, which did not expand at all for 1 mm in its proximal segment, while rest of the 24 mm length of the stent got fully expanded. Repeated attempts to expand the extremely focal unexpanded part of the stent at high pressure led to rupture of the stent balloon and its entrapment. We failed to retrieve the balloon using various techniques and the patient had to be sent for coronary artery bypass graft surgery.

RESUMEN

BACKGROUND: Transcatheter closure of coronary artery fistulas has emerged as a successful alternative to surgery. We describe various techniques and short-term findings in 15 patients who were taken up for transcatheter closure of these fistulas. METHODS AND RESULTS: Fifteen patients (aged 2-55 years; 12 males) with coronary artery fistulas underwent percutaneous transcatheter closure between June 1997 and December 2002. Site of origin of these fistulas were: right coronary artery in 7, left anterior descending coronary artery in 4, left main coronary artery in 2 and left circumflex coronary artery in 2 patients. Drainage site of these fistulas were: right ventricle in 9, right atrium in 4 and pulmonary artery in 2 patients. Out of these 15 fistulas, 14 were congenital and one was iatrogenically produced following inadvertent cutting balloon angioplasty of a septal perforator in a patient with chronic total occlusion of left anterior descending coronary artery. Various occlusion devices used to close these fistulas were: conventional metallic coils in 10, floppy tips of coronary angioplasty guidewires in 2, Amplatzer duct occluder in 1 and Amplatzer septal occluder in 2 patients. One of our patients had a coronary artery fistula draining by two openings into the right atrium, both of which were successfully closed using 2 Amplatzer duct occluders. Check angiogram after the procedure revealed complete occlusion in 13 (86.6%) and small residual flow in 2 patients. Follow-up studies at 3-55 months (mean 18 months) showed complete abolition of shunt in all patients with no evidence of recanalization leading to recurrence of shunt. CONCLUSION: Transcatheter closure of coronary artery fistulas is feasible and safe in the anatomically suitable vessels. Use of floppy tips of coronary angioplasty guidewires reduces the cost of the procedure significantly. which is an important consideration in developing countries like India.

RESUMEN

Stenting is the treatment of choice for treating stenotic renal ostial lesions. During the stenting of an ostial lesion in a renal artery with post-stenotic dilatation, we were faced with the problems of unavailability of a balloon of appropriate length and diameter, and determining the real reference vessel diameter. The problem was solved by a simple technique.

RESUMEN

Occlusion of a septal perforator branch alone, without the involvement of the left anterior descending coronary artery, leading to acute myocardial infarction is unusual. We report a case in which an isolated severely stenotic thrombus-containing first septal artery causing intractable post-myocardial infarction angina was successfully dilated and stented.

RESUMEN

Successful transcatheter closure of a perimembranous ventricular septal defect with an Amplatzer device has been reported in patients with levocardia. We report a case in which the device could be deployed successfully in a child with isolated perimembranous ventricular septal defect with situs inversus and dextrocardia.

RESUMEN

Atheromatous obstructive lesions of the arch vessels that contain thrombi are at high risk for distal embolization during angioplasty. This can lead to catastrophic neurological complications. We report a case of acute-on-chronic ischemia of the left upper limb due to thrombus-containing subclavian artery stenosis. After placement of an intravascular filter device, angioplasty and stent implantation successfully relieved the stenosis without any complications.
