We conclude that amiodarone is more effective than placebo in maintenance of SR at the end of 3 months following successful cardioversion and more patients continued to remain in SR even at the end of 12 months without major serious adverse effects.

Introduction: Tetrilimus (Sahajanand Medical Technologies Pvt. Ltd., Surat, India) is a recently-introduced biodegradable-polymer coated everolimus-eluting cobaltchromium coronary stent system with an ultra-thin strut thickness. We aimed to evaluate the clinical outcomes with Tetrilimus coronary stents in "real-world" patients with coronary artery disease. Methods: In this retrospective, single-arm, openlabel, multi-center registry, all consecutive patients who received Tetrilimus stents between July-2015 and April-2016 at two tertiary-care centers in India were analyzed. Primary endpoint was 30-day incidence of major adverse cardiac events (MACE), defined as a composite of cardiac death, myocardial infarction, target lesion revascularization, and target vessel revascularization. The Academic Research Consortium (ARC)-defined stent thrombosis was assessed as additional safety endpoint. Results: During the study period, 280 Tetrilimus stents (1.4 ± 0.5 stent/patient) were implanted to treat 252 coronary lesions (1.1 ± 0.3 stent/lesion) in 208 patients (age: 57.5 ± 11.9 years). Of study population, 65.9% were males, 46.6% were hypertensives, 25% were diabetics, 36.5% were alcoholics, 29.3% were smokers, 13.9% were tobacco chewers, 5.3% had previous revascularization, and 45.2% displayed multi-vessel disease. Of treated lesions, 67.5% were complex and 18.7% had total occlusion. Average length and diameter of implanted stents were 25.5 ± 8.8 mm and 2.9 ± 0.3 mm respectively. Subsequently, 30-day MACE were reported in 2 (0.96%) patients; both cases owing to in-hospital cardiac deaths. Events of stent thrombosis or noncardiac death were not reported in any patient. Conclusion: Low MACE rates and absence of stent thrombosis at early 30-day follow-up indicates that Tetrilimus everolimus

Complication rates following percutaneous interventions have decreased over the past decade due to advancement in both interventional equipment and procedure technique. Despite these advances, the risk of iatrogenic perforations still exists with associated high morbidity and mortality. We are presenting three cases of guidewire-induced perforations including coronary artery and renal artery perforation with their complications and successful management in these case-series.

The use of microcatheters as a coronary interventional tool for a therapeutic approach to complex coronary interventions like bifurcation lesions, ostial location, tortuous anatomy, angled takeoffs, coronary calcification, and chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is growing among cardiologists across the country. During the treatment of such complex lesions, microcatheters play an essential part of the tool kit with both single-lumen and double-lumen microcatheters (DLMs) having their specific niche areas. The selection of microcatheters involves a detailed understanding of the microcatheter specification, lesion anatomy, lesion location, vessel tortuosity and trajectory, and crossing techniques. The selection of appropriate crossing techniques with different microcatheters increases success rates of PCI, reduces procedural time and contrast use, and lowers the radiation. However, the use of microcatheters and their technicalities have not yet fully realized by many operators and their true scope has not been fully explored. This article discusses and summarizes the thoughts and key opinions of experts in this field.
