Loss and retrieval of a coronary angioplasty stent balloon
Abstract A case is presented in which a breakage of the coronary stent delivery catheter occurred as retrieval of the stent balloon was attempted after stent implantation. The broken distal…
Acquired peri-stent evaginations in a second generation durable polymer drug eluting stent
Abstract Hypersensitivity reaction towards the stent polymer resulting in formation of evaginations has been detected predominantly after treatment by the first generation drug eluting stents. This case shows that despite…
Percutaneous Implantation of A Parachute Device For Treatment of Ischemic Heart Failure
Abstract Congestive heart failure (CHF) secondary to ischemic cardiomyopathy is associated with significant morbidity and mortality despite currently available medical therapy. The Parachute TM device is a novel left ventricular…
Percutaneous transcatheter closure of infarct related ventricular septal defects assisted with portable miniaturized extracorporeal membrane oxygenation: A case series
Abstract Infarct associated ventricular septal defects (VSDs) are associated with considerable morbidity and mortality and are typically treated via an open surgical approach with the assistance of full mechanical bypass…
Occupational hazards of interventional cardiology
Abstract Complex catheter-based interventions and rising case volumes confer occupational risks to interventional cardiologists. Despite advances in technology, modern interventional procedures are performed in a manner remarkably similar to the…
Sympathetic renal denervation: Hypertension beyond SYMPLICITY
Abstract Despite a wide range of drug treatment for hypertension, resistant hypertension rates remain high. The Symplicity™ Renal Denervation System (Medtronic, Santa Rosa, CA), which creates renal nerve denervation, has…
Left ventricular end-diastolic pressure affects measurement of fractional flow reserve
Abstract Background Fractional flow reserve (FFR), the hyperemic ratio of distal (P d ) to proximal (P a ) coronary pressure, is used to identify the need for coronary revascularization….
Absence of a ‘smoker’s paradox’ in field triaged ST-elevation myocardial infarction patients undergoing percutaneous coronary intervention
Abstract Purpose The ‘smoker’s paradox’ refers to the observation of favorable prognosis in current smokers following an acute myocardial infarction (AMI). Initial positive findings were in the era of fibrinolysis,…
In vitro catheter and sorbent-based method for clearance of radiocontrast material during cerebral interventions
Abstract Background Contrast-induced acute kidney injury is a severe condition resulting from the use of radiology contrast in patients with predisposing factors. Hypothesis We hypothesized that a novel system including…
Direct stent puncture technique for intraluminal stent recanalization in the superficial femoral and popliteal arteries in-stent occlusion: Outcomes from a prospective clinical analysis of diabetics with critical limb ischemia
Abstract Purpose To evaluate the efficacy and safety of “Direct Stent Puncture” technique for intraluminal stent recanalization in the femoro-popliteal segments. Methods and Materials A cohort of diabetics who had…
