Swiss Cheese Heart: A Tale of Multiple Valve Perforations.

Gerbode defect, an anomalous connection between the left ventricle and right atrium, is often congenital but can be acquired or iatrogenically formed. We present an exceedingly rare case of this defect associated with multiple valve perforation in an otherwise healthy patient with bicuspid aortic valve and endocarditis.

Racial disparities among Asian Americans with atrial fibrillation: An analysis from the NCDR® PINNACLE Registry.

BACKGROUND: There is paucity of data on Atrial Fibrillation (AF) management and associated clinical outcomes among Asian Americans. This study sought to investigate baseline risk factor profiles, racial disparities in clinical management and adverse clinical outcomes among White and Asian Americans. METHODS: We used National Cardiovascular Data Registry (NCDR®) Practice Innovation and Clinical Excellence (PINNACLE) registry and linked Centers of Medicare and Medicaid Services data to identify Asian and White patients with AF between January 1, 2013-June 30, 2018. We compared rates of baseline risk factors, management strategies (rate versus rhythm control), anticoagulation use and rates of adverse events between racial groups. The two race groups were compared using hierarchical multivariable adjusted regression models to account for site and confounders. RESULTS: In total, 1,359,827 patients (18,793 Asians and 1,341,034 Whites) were included in our analysis. Compared to White Americans, Asian Americans were more likely to use a rate control strategy (Odds Ratio [OR]: 1.20, 95% Confidence Interval [CI]: 1.15-1.25) and lower odds of rhythm control strategy (atrial ablations, cardioversions, or use of antiarrhythmic drugs) (OR: 0.83, 95% CI: 0.80-0.87) in adjusted analysis. Use of oral anticoagulants and direct oral anticoagulants were similar. There were no significant race-based differences in likelihood of all-cause mortality, stroke, and bleeding requiring hospitalization. Analyses performed using propensity score matching were consistent with the main results. CONCLUSIONS: Asian Americans with AF have a lower likelihood of being managed with rhythm control strategies. Overall use of OAC and AF related adverse events remain similar between the two racial groups.

Revisiting transthyretin related cardiac amyloidosis: Case report and review of literature.

Amyloidosis is a complex group of disorders that can involve many organs and cause their dysfunction. Cardiac involvement indicates worse prognosis and influences treatment strategies. Cardiac amyloidosis is an under-diagnosed entity and high index of clinical suspicion and careful interpretation of basic diagnostic tools such as electrocardiogram and echocardiography is needed for early detection. Congestive heart failure due to restrictive pattern and/or conduction system abnormality, in absence of coronary artery disease should raise suspicion. We present a case of transthyretin related cardiac amyloidosis and discuss the key clinical and diagnostic findings along with review of existing literature regarding its management and outcomes.

Saphenous vein graft intervention: a review.

Saphenous vein grafts are prone to degeneration and occlusion. Vein graft disease continues to be a significant problem in maintaining long-term benefits after coronary artery bypass surgery. The neointimal hyperplasia and aggressive atherosclerosis that occur in saphenous vein grafts make interventions particularly challenging due to plaque embolization and the no-reflow phenomenon. This review discusses the pathophysiology of vein graft disease and the various percutaneous strategies that have been applied to manage vein grafts. We review the issues surrounding stent selection and various approaches to embolic protection devices. Finally, we discuss the technical steps that optimize success in treating this challenging patient subset.
