- Conduction Disturbances Associated with Transcatheter Aortic Valve Implantation: Challenge for another 20 Years?(2022) POZETTI, Antonio Helio; RIBEIRO, Henrique BarbosaTranscatheter aortic valve implantation (TAVI) is a well-established procedure for treating severe aortic stenosis in elderly patients, regardless of the surgical risk.(1) Since its introduction two decades ago, there have been major technological advances in devices, which, combined with new implantation techniques, have brought significant reductions in periprocedural complication rates, leading to their greater adoption worldwide. However, the incidence of conduction disorders showed a modest reduction, remaining the most frequent complication after TAVI,(2-4) which contributes to the increase in hospital stay, costs and the worsening of short and long-term clinical outcomes.(4.5) In addition, the approach to conduction disorders still varies greatly between centers, especially regarding the management of new left bundle branch block (LBBB), post-procedure advanced atrioventricular block (AVB) and previous right bundle branch block (RBBB), translated into variable rates of permanent pacemaker (PM) implantation.(3) Among patients who received PM after TAVI, there is also great variability regarding their dependence (ventricular pacing) at follow-up. In this journal edition, Pinto et al.(6) evaluated the incidence of conduction disorders, predictors and the rate of PM dependence in a population of 340 consecutive patients undergoing TAVI.(6) Conduction disorders occurred in more than 50% of post-procedure patients, with LBBB being the most frequent (32%), showing spontaneous resolution in 56% of them after 6 months. The overall PM implant rate was 18.5%, with prior RBBB being its main predictor. Among the patients who required PM, the main reasons were advanced AVB (60.3%), followed by LBBB with low-degree AVB (22%). Interestingly, there was a wide variation in the percentage of ventricular pacing among patients who received PM, being 83% in patients with advanced AVB (Advanced AVB and Mobitz Type II) and only 2% in those implanted with LBBB and low-degree AVB (first-degree AVB and Mobitz type I).(2-4.7) However, some aspects of this study deserve reflection.

- Recent Developments and Current Status of Transcatheter Aortic Valve Replacement Practice in Latin America - the WRITTEN LATAM Study(2022) BERNARDI, Fernando Luiz de Melo; RIBEIRO, Henrique Barbosa; NOMBELA-FRANCO, Luis; CERRATO, Enrico; MALUENDA, Gabriel; NAZIF, Tamim; LEMOS, Pedro Alves; SZTEJFMAN, Matias; LAMELAS, Pablo; ECHEVERRI, Dario; LOPES, Marcelo Antonio Cartaxo Queiroga; BRITO, Fabio Sandoli de; ABIZAID, Alexandre A.; MANGIONE, Jose A.; ELTCHANINOFF, Helene; SONDERGAARD, Lars; RODES-CABAU, JosepBackground: Transcatheter aortic valve replacement (TAVR) is a worldwide adopted procedure with rapidly evolving practices. Regional and temporal variations are expected to be found. Objective: To compare TAVR practice in Latin America with that around the world and to assess its changes in Latin America from 2015 to 2020. Methods: A survey was applied to global TAVR centers between March and September 2015, and again to Latin-American centers between July 2019 and January 2020. The survey consisted of questions addressing: i) center's general information; ii) pre-TAVR evaluation; iii) procedural techniques; iv) post-TAVR management; v) follow-up. Answers from the 2015 survey of Latin-American centers (LATAM15) were compared with those of other centers around the world (WORLD15) and with the 2020 updated Latin-American survey (LATAM20). A 5% level of significance was adopted for statistical analysis. Results: 250 centers participated in the 2015 survey (LATAM15=29; WORLD15=221) and 46 in the LATAM20. Combined centers experience accounted for 73 707 procedures, with WORLD15 centers performing, on average, 6- and 3-times more procedures than LATAM15 and LATAM20 centers, respectively. LATAM centers performed less minimalistic TAVR than WORLD15 centers, but there was a significant increase in less invasive procedures after 5 years in Latin-American centers. For postprocedural care, a lower period of telemetry and maintenance of temporary pacing wire, along with less utilization of dual antiplatelet therapy was observed in LATAM20 centers. Conclusion: Despite still having a much lower volume of procedures, many aspects of TAVR practice in Latin-American centers have evolved in recent years, following the trend observed in developed country centers.
- Sonothrombolysis Promotes Improvement in Left Ventricular Wall Motion and Perfusion Scores after Acute Myocardial Infarction(2022) TAVARES, Bruno G.; AGUIAR, Miguel Osman; TSUTSUI, Jeane; OLIVEIRA, Mucio; SOEIRO, Alexandre de Matos; NICOLAU, Jose; RIBEIRO, Henrique; POCHIANG, Hsu; SBANO, Joao; ROCHITTE, Carlos Eduardo; LOPES, Bernardo; RAMIREZ, Jose; KALIL FILHO, Roberto; MATHIAS, WilsonBackground: It has recently been demonstrated that the application of high-energy ultrasound and microbubbles, in a technique known as sonothrombolysis, dissolves intravascular thrombi and increases the angiographic recanalization rate in patients with ST-segment-elevation myocardial infarction (STEMI). Objective: To evaluate the effects of sonothrombolysis on left ventricular wall motion and myocardial perfusion in patients with STEMI, using real-time myocardial perfusion echocardiography (RTMPE). Methods: One hundred patients with STEMI were randomized into the following 2 groups: therapy (50 patients treated with sonothrombolysis and primary coronary angioplasty) and control (50 patients treated with primary coronary angioplasty). The patients underwent RTMPE for analysis of left ventricular ejection fraction (LVEF), wall motion score index (WMSI), and number of segments with myocardial perfusion defects 72 hours after STEMI and at 6 months of follow-up. P < 0.05 was considered statistically significant. Results: Patients treated with sonothrombolysis had higher LVEF than the control group at 72 hours (50% +/- 10% versus 44% +/- 10%; p = 0.006), and this difference was maintained at 6 months of follow-up (53% +/- 10% versus 48% +/- 12%; p = 0.008). The WMSI was similar in the therapy and control groups at 72 hours (1.62 +/- 0.39 versus 1.75 +/- 0.40; p = 0.09), but it was lower in the therapy group at 6 months (1.46 +/- 0.36 versus 1.64 +/- 0.44; p = 0.02). The number of segments with perfusion defects on RTMPE was similar in therapy and control group at 72 hours (5.92 +/- 3.47 versus 6.94 +/- 3.39; p = 0.15), but it was lower in the therapy group at 6 months (4.64 +/- 3.31 versus 6.57 +/- 4.29; p = 0.01). Conclusion: Sonothrombolysis in patients with STEMI resulted in improved wall motion and ventricular perfusion scores over time.
