چکیده انگلیسی
Atrioventricular block (AVB) after transcatheter aortic valve implantation (TAVI) is common. Pacing platforms that preserve atrioventricular (AV) synchrony may be beneficial in these patients. Single lead AV sequential pacemakers (VDD) allow AV synchrony and, by virtue of implanting a single lead, can be advantageous when compared with traditional dual lead (DDD) pacemakers. The objective of this retrospective case-controlled study was to compare the strategy of AV sequential pacing with a VDD versus DDD pacemaker in consecutive TAVI patients (nâ¯=â¯120) with acquired AVB. Patients were classified as receiving a VDD (nâ¯=â¯73) or DDD (nâ¯=â¯47) pacemaker. Procedure characteristics, complications, and the need for long-term ventricular pacing reported. Pacemaker implantation time (51 vs 66 minutes and p <0.001), fluoroscopy time (3.7 vs 7.8 minutes and pâ¯=â¯0.004), and radiation exposure (dose area product: 6.5 vs 15.3 mGy/cm2 and pâ¯=â¯0.006) were lower in patients receiving VDD pacemakers. Procedural complications were similar in the 2 groups. Overall, 59% of the cohort required â¥50% ventricular pacing at 1-year follow-up. In conclusion, VDD pacemaker implantation was associated with shorter procedure times, lower radiation exposure, and similar safety outcomes when compared with DDD pacemaker implantation in TAVI patients with acquired AVB.
