Does autopsy provide added value over clinical determination of cause of death in patients who die after TAVI?
Autopsy after TAVI frequently reveals unexpected findings and alters the clinically determined cause of death, highlighting its ongoing diagnostic value.
Autopsy after transcatheter aortic valve implantation (TAVI) is a new field of interest in cardiovascular pathology. To identify the cause of death, it is important to be familiar with specific findings related to the time interval between the procedure and death. We aimed to provide an overview of the autopsy findings in patients with TAVI in their medical history divided by the timing of death with specific interest in the added value of autopsy over a solely clinically determined cause of death. In 8 European centres, 72 cases with autopsy reports were available. Autopsies were divided according to the time interval of death and reports were analysed. In 32 patients who died ≤72 h postprocedure, mortality resulted from cardiogenic or haemorrhagic shock in 62.5 and 34.4%, respectively. In 31 patients with mortality >72 h to ≤30 days, cardiogenic shock was the cause of death in 51.6% followed by sepsis (22.6%) and respiratory failure (9.7%). Of the nine patients with death >30 days, 88.9% died of sepsis, caused by infective endocarditis in half of them. At total of 12 patients revealed cerebrovascular complications. Autopsy revealed unexpected findings in 61.1% and resulted in a partly or completely different cause of death as was clinically determined. Autopsy on patients who underwent TAVI reveals specific patterns of cardiovascular pathology that clearly relate to the time interval between TAVI and death and significantly adds to the clinical diagnosis. Our data support the role of autopsy including investigation of the cerebrum in the quickly evolving era of cardiac device technology.
Kesteren et al. (Fri,) conducted a observational in Mortality after transcatheter aortic valve implantation (TAVI) (n=72). Autopsy vs. Clinically determined cause of death was evaluated on Unexpected findings at autopsy resulting in a partly or completely different cause of death compared to clinical determination. Autopsy after transcatheter aortic valve implantation revealed unexpected findings in 61.1% of cases, resulting in a partly or completely different cause of death than clinically determined.
