Population
A total of 1,016 consecutive patients implanted with a Micra TPS LPM during the inclusion period were screened, of whom 99 (9.7%) met the inclusion criteria. Clinical characteristics of patients are reported inTable 1 .
The primary diagnosis for admission in ICU was cardiovascular in 86 patients (87%): extreme bradycardia (n=30) or cardiac arrest (n=2), ventricular arrhythmias (n=2), post-operative following transcatheter aortic valve replacement (n=26) or open-chest cardiac surgery (n=8), cardiogenic shock (n=8) or heart failure (n=3), and endocarditis (n=7). Other main diagnoses were: septic shock (n=2) or sepsis (n=1) (excluding endocarditis), acute respiratory distress syndrome (n=3), post-operative following abdominal surgery (n=3), ketoacidosis (n=1), hypovolemic shock (n=1), hepatic encephalopathy (n=1), and severe burn (n=1).
