Single Center 7 Year Experience of Coronary Artery Perforation: Angiographic and Procedural Characteristics, Management and Outcome.

CONTEXT: Coronary artery perforation is a rare but potentially catastrophic complication of percutaneous coronary intervention (PCI). It is infrequent complication of PCI. AIMS: The objective of the study is to report the 7-year experience of coronary artery perforation with respect to incidence, clinical and angiographic characteristics, management and outcomes. SETTINGS AND DESIGN: The study involved retrospective analysis of single centre 7 years of percutaneous coronary intervention data. Patients who had complication of coronary artery perforation during PCI were identified and included in the study. SUBJECTS AND METHODS: Retrospective analysis of clinical, angiographic and procedural characteristics as well as management and outcome of coronary artery perforation was done. STATISTICAL ANALYSIS USED: The whole data were tabulated, variables were presented as mean and percentages and comparison was done within them. RESULTS: A total of 37 cases of coronary artery perforation were identified from 4532 PCI performed. Most of the coronary artery perforation belonged to Ellis Type II and Type III (both n = 15) followed by Type III CS and Type I. Lesions belonged to AHC/AHA Type C in 31 cases. Most frequent mechanism of coronary artery perforation was related to the use of guidewire and balloon (both n = 17). The total of 8 cases presented with cardiac tamponade requiring pericardiocentesis. Eleven cases required emergency covered stent implantation. In two cases microcoil was used while one case required polyvinyl alcohol particles to seal the perforation site. There was no in-hospital mortality while 30-day mortality occurred in one patient. One case was referred for emergency surgery. CONCLUSIONS: Coronary artery perforation is rare but potentially fatal complication of percutaneous coronary intervention. Complication of coronary artery perforation can be managed effectively in the catheterization laboratory without the need of emergency of bailout surgery and in-hospital outcomes remain good in the majority of cases.

Percutaneous coronary intervention in a rare case of Type V dual LAD.

Congenital coronary anomalies are rare and reported to occur in 0.64-1.3% of patients undergoing coronary angiography. The dual left anterior descending coronary artery (LAD) is a rare coronary anomaly defined as the presence of two LADs in the anterior interventricular sulcus (AIVS). It consists of a short LAD that ends high in the AIVS and a longer LAD that enters the distal AIVS and feeds apex. Percutaneous interventions are even more uncommon in dual LAD especially Type V LAD. Thus we describe an interesting case of percutaneous transluminal coronary angioplasty (PTCA) with stenting to Type V dual LAD in a patient with chronic stable angina who was refractory to maximal anti-anginal medications. Our case was unique for these aspects - 1)Type V dual LAD is rare.2)Ramus artery is present in fewer cases of dual LAD.3)Long LAD had a myocardial bridge.4)Few cases have been reported of PTCA with stenting to short LAD. .

Successful percutaneous retrieval of unusually knotted temporary pacemaker lead.

Implantation of temporary pacemaker lead is commonly performed procedure and is usually safe, but can sometimes develop rare and serious complication like intracardiac lead knotting which may require challenging retrieval techniques. We report a case of successful percutaneous retrieval of unusually knotted right internal jugular venous temporary pacing lead via left femoral transvenous approach using snare over a long sheath after cutting the electrode proximally and thus avoiding any surgical intervention.
