Background: The contribution of autonomic influences to atrioventricular block (AVB) is unclear. Although cardioneuroablation has been used to treat cardioinhibitory vasovagal syncope, its role in treating functional paroxysmal and persistent AVB has not been formally evaluated. Methods: We used a stepwise protocol in 241 consecutive patients presenting with symptomatic AVB to identify 31 (12.9%) patients with functional or vagally mediated AVB. All patients had episode(s) of syncope in previous 12 months, and AVB was persistent in 17 (54.8%) patients. All 31 patients received targeted catheter-based cardioneuroablation, and their follow-up outcomes were evaluated with serial Holter monitoring. Results: Twenty-eight patients received biatrial or left-sided cardioneuroablation while 3 received only right-sided cardioneuroablation because of structural factors that precluded safe attempts at transseptal puncture. Procedural success, as defined as acute reversal of AVB and complete abolition of atropine response, was achieved in 30 (96.7%) cases, while the remaining patient received a pacemaker. Over a mean follow-up of 19.3±15 months, AVB episodes were observed in 2 (6.7%) of 30 cases, and 3 (9.6%) patients required pacemaker implantation during follow-up. Conclusions: Functional AVB can be identified in a minority of patients presenting with high-grade AVB. Cardioneuroablation for these patients results in encouraging medium-term outcomes.

<p><b>Objectives:</b> Despite increasing recognition that off-pump coronary artery bypass surgery and sequential grafting strategy individually are associated with improved outcomes, concerns persist regarding the safety and efficacy of combining these 2 techniques. We compared in-hospital and midterm outcomes for off-pump multivessel sequential and conventional coronary artery bypass grafting.</p><p><b>Methods:</b> From September 1998 to September 2008, 689 consecutive patients received off-pump multivessel sequential coronary artery bypass grafting performed by a single surgeon. These patients were propensity matched to 689 patients who underwent off-pump coronary artery bypass grafting without sequential anastomoses. A retrospective analysis of prospectively collected perioperative data was performed. In addition, medical notes and charts of all the study patients were reviewed. The mean duration of follow-up was 5.1 � 2.0 years.</p><p><b>Results:</b> The major in-hospital clinical outcomes in the sequential and control groups were found to be similar. After adjusting for clinical covariates, sequential grafting was not an independent predictor of in-hospital adverse events (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.86-1.50; <i>P</i> = .31), medium-term mortality (hazard ratio [HR], 1.26; 95% CI, 1.06-1.32; <i>P</i> = .92), and readmission to hospital (HR, 1.12; 95% CI, 0.96-1.20; <i>P</i> = .80). Sequential grafting was an independent predictor of receiving more than 3 distal anastomoses (OR, 7.46; 95% CI, 4.27-11.45; <i>P</i> < .0001). Risk-adjusted survival was 89% for sequential grafting patients and 88% for conventional grafting patients (<i>P</i> = .96) during the medium-term follow-up.</p><p><b>Conclusion:</b> Our analysis confirms the short- and midterm safety and efficacy of off-pump sequential coronary artery bypass grafting.</p>

The Future

Existing research suggests that adults and older children experience a tradeoff where instruction and feedback help them solve a problem efficiently, but lead them to ignore currently irrelevant information that might be useful in the future. It is unclear whether young children experience the same tradeoff. Eighty-seven children (ages five- to eight-years) and 42 adults participated in supervised feature prediction tasks either with or without an instructional hint. Follow-up tasks assessed learning of feature correlations and feature frequencies. Younger children tended to learn frequencies of both relevant and irrelevant features without instruction, but not the diagnostic feature correlation needed for the prediction task. With instruction, younger children did learn the diagnostic feature correlation, but then failed to learn the frequencies of irrelevant features. Instruction helped older children learn the correlation without limiting attention to frequencies. Adults learned the diagnostic correlation even without instruction, but with instruction no longer learned about irrelevant frequencies. These results indicate that young children do show some costs of learning with instruction characteristic of older children and adults. However, they also receive some of the benefits. The current study illustrates just what those tradeoffs might be, and how they might change over development.

Surgical Myectomy

Abstract Introduction Alcohol septal ablation (PTSMA) was introduced as interventional alternative to surgical myectomy for symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM) 25 years ago. As gender differences in diagnosis and treatment of HOCM are still unclear we analyzed baseline characteristics and results of PTSMA in a large single center cohort with respect to gender. Methods and results Between 05/2000 and 06/2017 first PTSMA in our center was performed in 952 patients with symptomatic HOCM. We treated less 388 (40.8%) women and 564 (59.2%) men. All patients underwent clinical follow-up. At the time of the intervention women were older (61.2±14.9 vs. 51.9±13.7 years; p&lt;0.0001) and suffered more often from NYHA grade III/IV dyspnea (80.9% vs. 68.1%; p&lt;0.0001), whereas angina pectoris was comparable in women (62.4%) and men (59.9%). Echocardiographic baseline gradients were comparable in women (rest 65.0±38.1 mmHg and Valsalva 106.2±45.7 mmHg) and men (rest 63.1±38.3 mmHg and Valsalva 103.6±42.8 mmHg). But, women had smaller diameters of the left atrium (44.3±6.9 vs. 47.2±6.5 mm; p&lt;0001), maximal septum thickness (20.4±3.9 vs. 21.4±4.5 mm; p&lt;0.01), and maximal thickness of the left ventricular posterior wall (12.7±2.8 vs. 13.5±2.9 mm; p&lt;0.0001). In women, more septal branches (1.3±0.6 vs. 1.2±0.5; p&lt;0.05) had to be tested to identify the target septal branch. The amount of injected alcohol was comparable (2.0±0, 4 in women vs. 2.1±0.4 ml in men). The maximum CK increase was lower in women (826.0±489.6 vs. 903.4±543.0 U / l; p&lt;0.05). During hospital stay one woman and one man died, each (n.s.). The frequency of total AV blocks in the cathlab showed no significant difference between women (41.5%) and men (38.3%). Furthermore, the rate of permanent pacemaker implantation during hospital stay did not differ (12.1% in women vs. 9.4% in men). Follow-up periods of all patients showed no significant difference between women (5.7±4.9 years) and men (6.2±5.0 years). Overall, 37 (9.5%) women died during this period compared to only 33 (5.9%) men (p&lt;0.05). But, cardiovascular causes of death were not significantly different between women (2.8%) and men (1.6%). Furthermore, the rates of surgical myectomy after failed PTSMA (1.3% in women vs. 2.3% in men), ICD implantation for primary prevention of sudden cardiac death according to current guidelines (4.1% in women vs. 5.9% in men) or pacemaker implantation (3.6% in women vs. 2.0% in men) showed no significant differences. Summary PTSMA in women with HOCM was performed at more advanced age with more pronounced symptoms compared to men. While there were no differences in acute outcomes, overall long-term mortality was higher in women without differences in cardiovascular mortality. Therefore, women may require more intensive diagnostic approaches in order not to miss the correct time for gradient reduction treatment. Funding Acknowledgement Type of funding source: None
