Performance of percutaneous coronary intervention (PCI) is associated with several occupational hazards including radiation exposure and musculoskeletal injury. Current methods to mitigate these risks range from suspended radiation suits to adjustable lead-lined glass shields. Robotic-assisted PCI is a novel approach to PCI that utilizes remote-controlled technology to manipulate catheters thereby significantly reducing radiation exposure to the operator and catheterization laboratory staff. Although limited, current evidence indicates that robotic-assisted PCI is associated with a high technical success rate and may have additional advantages over conventional PCI, such as a decreased incidence of geographical miss...

Infections involving internal cardiac devices can be very challenging to treat, and almost universally require complete device extraction for successful management. Of the pathogens that cause device-related endocarditis, fungi such as Candida albicans are notoriously difficult to manage because of their propensity to produce large vegetations and the need for long-term treatment with potentially toxic medications. Furthermore, individuals who develop fungal, device-associated endocarditis are typically among the most complex patients, with significant comorbidities that place them at high risk for open heart procedures such as surgical device extraction...

OBJECTIVES: To compare mid-term outcomes between patients undergoing proximal left anterior descending artery (LAD) percutaneous coronary intervention (PCI) with second generation drug-eluting stent (DES) or bare-metal stent (BMS). BACKGROUND: PCI with BMS and first-generation DES have shown to be safe options for the treatment of proximal LAD stenosis, however associated with considerable reintervention rates. Overall, second-generation DES has proven to be superior to BMS and first-generation DES, nevertheless, its effect for proximal LAD PCI has not previously been reported...

We report a case of percutaneous coronary intervention with drug coated balloon (DCB) for the in-stent restenosis of polytetrafluoroethylene-covered stent. One year follow-up angiography was excellent and in-stent lumen enlargement compared with the postprocedure and 6-months follow-up was demonstrated by optical coherent tomography. This case suggested the utility of DCB as a therapeutic option for covered-stent restenosis.

Long term follow up studies have shown that transcatheter closure of perimembranous Ventricular Septal Defect (PmVSD) can be done safely and successfully. One of the most serious complications of VSD device closure is complete atrioventricular block which has been reported in 3-18% is various studies following VSD device closure. Amplatzar Duct Occluder II (ADO-II) device is now commonly being used for closure of small to moderate sized PmVSD. Complete heart block has not been reported with ADO-II device. We are reporting 2 cases of complete heart block following transcatheter closure of PmVSD using ADO-II device where sinus rhythm was established following early surgical removal of the device...

OBJECTIVE: To examine the relationship between occupational exposure to ionizing radiation and the prevalence of lens changes in interventional cardiologists (ICs) and catheterization laboratory ("cath-lab") staff. BACKGROUND: Exposure to ionizing radiation is associated with the development of lens opacities. ICs and cath-lab staff can receive high doses of ionizing radiation without protection, and may thus be at risk for lens opacity formation. METHODS: We conducted a cross-sectional study at an interventional cardiology conference...

BACKGROUND: Patients with diabetes mellitus (DM) remain at higher risk of restenosis after percutaneous coronary intervention despite the use of contemporary drug-eluting stents. The Cre8 amphilimus-eluting stent (AES) has shown promising results in DM patients. Whether this holds true irrespective of patient's clinical and angiographic complexity is unknown. METHODS: Five hundred and ninety five consecutive patients (738 lesions) undergoing AES implantation were included in the INVESTIG8 multicenter registry...
