A 69‐year‐old woman with diabetes was found to have multi‐vessel coronary artery disease and underwent 5‐vessel coronary artery bypass grafting. Patient had persistent cardiogenic shock postoperatively despite intra‐aortic balloon pump and escalating pressor requirements. Electrocardiogram showed new ischemic changes and the patient was urgently taken to the catheterization lab for coronary angiography and placement of an Impella CP for higher degree of hemodynamic support via the left femoral artery. Due to limitations in vascular access the Impella CP sheath was utilized for vascular access for diagnostic angiography and coronary intervention concurrently with ongoing Impella CP support. The first obtuse marginal had severe proximal disease and was treated with percutaneous coronary intervention (PCI) with a drug eluting stent. To our knowledge, this case is the first in which successful diagnostic angiography as well as multi‐vessel PCI was performed via an Impella sheath while concurrently using the percutaneous mechanical circulatory support system of the Impella CP. Multiple guide catheters and a pigtail catheter were successfully passed via the Impella CP sheath to perform PCI. This novel method of vascular access could be an important tool to use in high‐risk patients with limitations in access sites and decrease potential bleeding complications by limiting the number of arterial punctures.

Background. Utilization of colonoscopy for routine colorectal cancer (CRC) screening in the elderly (patients over 75) is controversial. This study was designed to evaluate if using fecal occult blood test (FOBT) to select patients for colonoscopy can improve yield and be a cost- effective approach for the elderly. Methods. Records of 10,908 subjects who had colonoscopy during the study period were reviewed. 1496 (13.7%) were ≥75 years. In 118 of these subjects, a colonoscopy was performed to evaluate a positive FOBT. Outcomes were compared between +FOBT group (F-Group) and the asymptomatic screening group (AS-Group). The cost-effectiveness was also calculated using a median estimated standardized worldwide colonoscopy and FOBT cost (rounded to closest whole numbers) of 1000 US $ and 10 US $, respectively. Results. 118/1496 (7.9%) colonoscopies were performed for evaluation of +FOBT. 464/1496 (31%) colonoscopies were performed in AS-Group. In F-Group, high risk adenoma detection rate (HR-ADR) was 15.2%, and 11.9% had 1-2 tubular adenomas. In comparison, the control AS-Group had HR-ADR of 19.2% and 17.7% had 1-2 tubular adenomas. In the FOBT+ group, CRC was detected in 5.1% which was significantly higher than the AS-Group in which CRC was detected in 1.7% (P = 0.03). On cost-effectiveness analysis, cost per CRC detected was significantly lower, that is, 19,666 US $ in F-Group in comparison to AS-Group 58,000 US $ (P < 0.05). There were no significant differences in other parameters among groups. Conclusion. Prescreening with FOBT to select elderly for colonoscopy seems to improve the yield and can be a cost-effective CRC screening approach in this subset. The benefit in the risk benefit analysis of screening the elderly appears improved by prescreening with an inexpensive tool.

Haemophilia A is a rare genetic condition leading to coagulation factor VIII deficiency and thus predisposing to bleeding diathesis. Due to advances in treatment, life expectancy of haemophilia A sufferers is increasing, and the incidence and prevalence of coronary artery disease are rising. There have been many reported cases of acute myocardial infarction in such patients, who subsequently undergo elective percutaneous coronary intervention. We present the case of a 55-year-old gentleman presenting with an acute anterior full-thickness myocardial infarction who required emergency primary percutaneous coronary intervention.

An 82-year-old woman with severe respiratory distress and limitations in functional status was found to have severe mitral valve stenosis with annular calcification and referred for transcatheter mitral valve replacement. Prophylactic alcohol septal ablation was used pre-procedurally to minimize mortality risk due to obstruction of the left ventricular outflow tract. ( Level of Difficulty: Intermediate. )
