Article Synopsis
- The study examined the rising use of transcatheter aortic valve implantation (TAVI) in New South Wales, Australia, analyzing real-world data on patient prevalence and outcomes from 2013 to 2018.
- Case volumes of TAVI procedures significantly increased from 30 in 2013 to 345 in 2017, with a patient cohort averaging 83.3 years old, and overall mortality rates at various intervals were reported.
- Heart failure, myocardial infarction, and sepsis were identified as major causes of in-hospital deaths, indicating that pre-existing health issues and the performance of the procedure at lower-volume centers could impact patient outcomes significantly.
Background: Symptomatic pulmonary embolism (PE) is a major cause of cardiovascular death and morbidity. Estimated prevalence and incidence of atrial fibrillation (AF) in developed countries are between 388-661 per 100,000, and 90-123 per 100,000 person-years respectively. However, the prevalence and incidence of AF in patients presenting with an acute PE and its predictors are not clear.

Methods: Clinical details of all patients (n = 1023) admitted to a tertiary institution from 2000-2007 with acute PE were retrieved retrospectively.
Objectives: It was the aim of this study to determine the prognostic significance of the Charlson Comorbidity Index (CCI) following acute pulmonary embolism (PE) and assess the prognosis of patients without comorbidities (defined as a CCI score of 0).
Methods: Outcomes of 1,023 consecutive patients admitted with confirmed PE were tracked after a median of 3.7 years (25-75th interquartile range 1.
Background: Although cardiac troponin elevation during acute pulmonary embolism (PE) predicts in-hospital death, its long-term prognostic significance, and the role of troponin-T concentration in this prediction, is unknown. Moreover, its use in acute PE in elderly populations with multiple comorbidities is not well described.
Methods: Consecutive patients presenting with confirmed PE to a tertiary hospital between 2000 and 2007 with troponin-T measured were identified retrospectively and their outcomes tracked from a state-wide death registry.
Background: There are currently no guidelines advising long-term surveillance of patients following an acute pulmonary embolism (PE), because long-term outcome studies are rare. We investigated the long-term cardiovascular and all-cause mortality of a large patient cohort with confirmed PE in relation to baseline cardiovascular disease (CVD).
Methods And Results: Clinical details of all patients presenting with acute PE to a tertiary hospital were retrieved from medical records, and their survival tracked from a statewide death registry.
During the modified Bentall operation (aortic root replacement), a cuff of native aorta is commonly implanted together with the coronary ostium into the aortic graft. We describe the radiologic appearance on computed tomography of coronary-aortic and aorto-aortic graft anastomoses over long-term follow-up in 21 consecutive asymptomatic patients (mean age, 67 +/- 12 years) with previous Bentall operation. Multidetector (64-slice, dual-source) computed tomography was performed at a median of 76 months after surgery.
