We present a rare and unique case of calcific constrictive pericarditis with a calcified pericardial mass invading the right ventricular myocardium. Perioperative two-dimensional and three-dimensional transesophageal echocardiography revealed the extent and structure of the pericardial mass and led to the repair of the right ventricular free wall as a surgical intervention.

Modern cardiac surgery has rapidly evolved to treat complex cardiovascular disease. This past year boasted noteworthy advances in xenotransplantation, prosthetic cardiac valves, and endovascular thoracic aortic repair. Newer devices often offer incremental design changes while demanding significant cost increases that leave surgeons to decide if the benefit to patients justifies the increased cost. As innovations are introduced, surgeons must continuously aim to harmonize short- and long-term benefits with financial costs). We must also ensure quality patient outcomes while embracing innovations that will advance equitable cardiovascular care.

Background: This study assessed the incidence of lower limb ischemia as well as trends in management and outcomes while examining acute aortic dissection patients over a period of 15 years. Additionally, differences in clinical presentation, interventions performed, and mortality between patients with and without lower limb ischemia were investigated. Methods: Lower limb ischemia (LLI) was evaluated among 3812 patients enrolled in the International Registry of Acute Aortic Dissection over a 15-year period that was separated into three 5-year intervals: 1996-2001, 2002-2007, and 2008-2012. The cohort was then divided by dissection type and presence or absence of LLI. Results: Type A patients presenting with limb ischemia (N=280, 11.4%) were much more likely to have atherosclerosis (p=0.021) and to present with back, abdominal and leg pain versus chest pain (p<0.001 unless noted). Other symptoms of malperfusion, including ischemic spinal cord damage (p<0.001) and coma/altered consciousness (p=0.006) were more common in patients presenting with LLI. Surgery was less commonly performed in Type A LLI patients (79.3% vs 86.1%, p=0.002), a difference that did not change over time (p=0.453, trend p=0.479). Additionally, overall mortality was higher in LLI patients (37.5% vs 22.9%, p<0.001) and did not show improvement among the LLI cohort over time. Type B patients with LLI (N=102, 7.5%) were more likely to be current smokers (p=0.028), to present febrile (p=0.022), and to have leg pain (p<0.001). As with Type A, ischemic spinal cord damage was more common in the LLI cohort (p<0.001). Patients with LLI were much more likely to be managed with endovascular therapy (19.6% vs 50.0%, p<0.001) than with medication alone (66.5% vs 29.4%, p<0.001), with endovascular repair increasing in LLI patients over time (p=0.008, trend p=0.002). Again, overall mortality was higher in the LLI cohort (24.5% vs 9.7%, p<0.001) and did not change over time. Conclusions: Although Type B patients with LLI received more endovascular procedures in later years, overall mortality did not improve. Increased complications and higher mortality in the LLI cohort suggests a need for better monitoring and increased implementation of interventions in this population.
