Trends in tracheal, bronchial and lung cancer attributed to smoking in South America: Global Burden of Disease analysis 1990-2019.

Objective: To investigate the burden of tracheal, bronchus, and lung (TBL) cancer due to tobacco exposure in the last 30 years in 12 South American countries. Methods: We used the Global Burden of Disease (GBD) 2019 exposure-response function to analyze the total tobacco, smoking, and secondhand smoke exposure-related TBL cancer deaths and disability-adjusted life years (DALYs), for 12 South American countries, between 1990 and 2019. Metrics were described as absolute numbers or rates per 100 000 individuals. The relative change in burden was assessed by comparing the 1990-1994 to 2015-2019 periods. Results: In 2019, the all-ages number of TBL cancer deaths and DALYs associated with tobacco exposure in South America was 29 348 and 658 204 in males and 14 106 and 318 277 in females, respectively. Age-adjusted death and DALYs rates for the region in 2019 were 182.8 and 4035 in males and 50.8 and 1162 in females, respectively. In males, 10/12 countries observed relative declines in TBL death rates attributed to tobacco exposure while only 4 countries reduced their mortality in females. Conclusion: While significant efforts on tobacco control are under place in South America, substantial burden of TBL cancer persists in the region with significant sex-specific disparities. Increased country-specific primary data on TBL cancer and tobacco exposure is needed to optimize healthcare strategies and improve comprehension of regional trends.

In-Stent Restenosis Overview: From Intravascular Imaging to Optimal Percutaneous Coronary Intervention Management.

Despite ongoing progress in stent technology and deployment techniques, in-stent restenosis (ISR) still remains a major issue following percutaneous coronary intervention (PCI) and accounts for 10.6% of all interventions in the United States. With the continuous rise in ISR risk factors such as obesity and diabetes, along with an increase in the treatment of complex lesions with high-risk percutaneous coronary intervention (CHIP), a substantial growth in ISR burden is expected. This review aims to provide insight into the mechanisms, classification, and management of ISR, with a focus on exploring innovative approaches to tackle this complication comprehensively, along with a special section addressing the approach to complex calcified lesions.

Our study included the 12 sovereign countries of SA (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela) with data available at the GBD 2019. Using GHDx (11), the age-adjusted mortality per 100 000 individuals and the age-adjusted Disability adjusted Life years (DALYs) per 100 000 individuals for TBL cancer between 1990 and 2019 were obtained. Age-adjusted mortality and DALYs rates are provided together with 95% uncertainty intervals (UI). The 95% uncertainty intervals are determined by the 25th and 75th value of the 1000 values after ordering them from smallest to largest. (15) Absolute numbers and rates (per 100 000 individuals) for 5-year age groups were also obtained. Sex-specific disparities were assessed by obtaining data for females and males. Furthermore, besides analyzing the burden of TBL cancer due to tobacco, we evaluated the contribution of smoking and secondhand smoke to TBL mortality and DALYs.

[RESUMEN]. Objetivo. Investigar la carga del cáncer de tráquea, bronquios y pulmón por exposición al tabaco en los últi- mos 30 años en 12 países de Sudamérica. Métodos. Se utilizó la función de relación entre exposición y respuesta de la carga mundial de morbilidad del 2019 para analizar las muertes por cáncer de tráquea, bronquios y pulmón asociadas a la exposición total al tabaco, al tabaquismo activo y al tabaquismo pasivo, así como los años de vida ajustados en función de la discapacidad (AVAD), en 12 países de Sudamérica, entre 1990 y el 2019. Los resultados se presentaron en forma de número absoluto o de tasa por 100 000 personas. Se evaluó el cambio relativo de la carga mediante la comparación de los períodos 1990-1994 y 2015-2019. Resultados. En el 2019, el número de muertes por cáncer de tráquea, bronquios y pulmón y los AVAD aso- ciados a la exposición al tabaco para todas las edades en Sudamérica fueron de 29 348 y 658 204 en los hombres y de 14 106 y 318 277 en las mujeres, respectivamente. La tasa de mortalidad y los AVAD ajustados por la edad correspondientes al 2019 en la región fueron de 182,8 y 4035 en los hombres y de 50,8 y 1162 en las mujeres, respectivamente. En el caso de los hombres, en 10 de los 12 países se observaron disminuciones relativas de la tasa de mortalidad por cáncer de tráquea, bronquios y pulmón atribuido a la exposición al tabaco, mientras que en el caso de las mujeres solo en 4 países hubo una reducción de la mortalidad. Conclusión. Aunque en Sudamérica se están llevando a cabo iniciativas importantes para el control del tabaco, en esta región persiste una carga considerable de cáncer de tráquea, bronquios y pulmón, con diferencias significativas en función del sexo. Es preciso contar con más datos primarios específicos de cada país sobre el cáncer de tráquea, bronquios y pulmón, así como sobre la exposición al tabaco, para optimizar las estrategias de atención de salud y mejorar la comprensión de las tendencias regionales.

Cor-Knot Use in SAVR Facilitates Coplanar Angle Adjustment During TAVR.

The Cor-Knot surgical tying device (LSI Solutions) is an automated suture fastener with a titanium-crimpable sleeve that facilitates a fast and secure knot. The device is an alternative to hand tying, minimizing operation time, and its increasing use is anticipated for minimally invasive cardiac surgeries or in patients with small surgical anatomy. As its use expands, the likelihood of encountering this knotting device during structural interventions may increase. In this case, during the TAVR procedure, the coplanar angle estimated from preoperative computed tomography scan was easily adjusted referencing the line of Cor-Knot in her aortic annulus without administrating contrast despite poor radiodensity from the Trifecta valve. In the coplanar view, the TAVR valve depth was well appreciated in reference to the Cor-Knot line and the TAVR valve was deployed under controlled pacing without contrast use. We achieved mean aortic pressure gradient of 9 mm Hg without paravalvular leakage or conduction abnormalities. She was discharged to home the next day without renal injury.

Clinical impact of right ventricular pacing burden in patients with post-transcatheter aortic valve replacement permanent pacemaker implantation.

AIMS: Patients who undergo permanent pacemaker (PPM) implantation after transcatheter aortic valve replacement (TAVR) have a worse outcome. The aim of this study was to identify risk factors of worse outcomes in patients with post-TAVR PPM implantation. METHODS AND RESULTS: This is a single-centre, retrospective study of consecutive patients who underwent post-TAVR PPM implantation from 11 March 2011 to 9 November 2019. Clinical outcomes were evaluated by landmark analysis with cut-off at 1 year after the PPM implantation. Of the 1389 patients underwent TAVR during the study duration and a total of 110 patients were included in the final analysis. Right ventricular pacing burden (RVPB) ≥ 30% at 1 year was associated with a higher likelihood of heart failure (HF) readmission [adjusted hazard ratio (aHR): 6.333; 95% confidence interval [CI]: 1.417-28.311; P = 0.016] and composite endpoint of overall death and/or HF (aHR: 2.453; 95% CI: 1.040-5.786; P = 0.040). The RVPB ≥30% at 1 year was associated with higher atrial fibrillation burden (24.1 ± 40.6% vs. 1.2 ± 5.3%; P = 0.013) and a decrease in left ventricular ejection fraction (-5.0 ± 9.8% vs. + 1.1 ± 7.9%; P = 0.005). The predicting factors of the RVPB ≥30% at 1 year were the presence of RVPB ≥40% at 1 month and the valve implantation depth measured from non-coronary cusp ≥4.0 mm (aHR: 57.808; 95% CI: 12.489-267.584; P < 0.001 and aHR: 6.817; 95% CI: 1.829-25.402; P = 0.004). CONCLUSIONS: The RVPB ≥30% at 1 year was associated with worse outcomes. Clinical benefit of minimal RV pacing algorithms and biventricular pacing needs to be investigated.

Emergent Endovascular Repair of a Ruptured Ascending Aorta Pseudoaneurysm With Thoracic Aortic Stent Graft.

Pseudoaneurysm of the ascending aorta is a rare complication of cardiac surgery due to tissue degeneration at the site of graft anastomosis, aortotomy, or extracorporeal circulation cannulation. We describe the case of a patient who developed an ascending aorta pseudoaneurysm after coronary artery bypass graft surgery, which initially required percutaneous closure with an atrial septal defect occlusion device. However, three years later the patient presented again with active external bleeding secondary to pseudoaneurysm enlargement and rupture, which was emergently repaired by percutaneous endovascular repair with a thoracic aortic stent graft. At one-year follow-up the patient is in good conditions and asymptomatic.

Feasibility of coronary angiogram-derived vessel fractional flow reserve in the setting of standard of care percutaneous coronary intervention and its correlation with invasive FFR.

BACKGROUND: Vessel Fractional Flow Reserve (vFFR), a new angiography-derived method for the functional assessment of coronaries, was recently shown to have good correlation with invasive wire-derived FFR, when vFFR-specific image acquisition requirements were followed. We sought to investigate the feasibility of vFFR analysis and its correlation with FFR in the situation where angiography is completed in routine fashion, without intention for virtual analysis. METHODS: Utilizing an anonymized database maintained at our Cardiovascular Imaging Core Laboratory, we included angiographic images from patients that underwent pre- and post-PCI FFR. CAAS Workstation 8.1 software (Pie Medical Imaging) was used for vFFR evaluation. RESULTS: Out of 624 angiograms (312 pre-PCI and 312 post-PCI), vFFR was successfully analyzed in 219 (35.1%) (115 pre-PCI and 104 post-PCI). Reasons for vFFR analysis failure were: <2 angiographic projections (42.5%), table movement while acquisition (25.7%) and resolution incompatibility (15%). From 115 patients with analyzable pre-PCI vFFR, 74 (64.3%) showed agreement with the respective FFR results in terms of positive (≤0.80) vs negative (>0.80) FFR. Pearson's correlation coefficient between them was 0.449 (p < 0.0001). From 104 lesions with analyzable post-PCI vFFR, 94 had availability of FFR, 74 (78.7%) of which showed agreement between the vFFR and FFR. Pearson's correlation between the values was 0.115 (p = 0.2703). CONCLUSION: vFFR could be analyzed in about one-third of previously completed angiographies and a weak correlation was seen between vFFR and FFR. Our results show the importance of following the pre-specified requirements for vFFR analysis. Further studies are needed to validate the software in different settings.
