(Heart rhythm) Full episode page: https://podcast.explainheart.com/podcast/left-bundle-pacing-challenges-bivp-for-crt-04-14-26/ Featured Articles Article 1: Ultrasound-guided vs conventional venous puncture for atrial fibrillation ablation: the ULYSSES trial. Journal: European heart journal PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41979041 Summary: The ULYSSES trial confirmed that vascular access site complications are the most common procedure-related adverse events during atrial fibrillation catheter ablation. This study directly compared an ultrasound-guided femoral venous puncture strategy with a conventional approach. The multicenter trial evaluated the efficacy of each technique in reducing complications in patients undergoing atrial fibrillation or left atrial tachycardia catheter ablation. The investigation’s findings provided a critical evidence base for optimizing patient safety during these procedures. Article 2: Left bundle branch area vs biventricular pacing for cardiac resynchronization therapy: the LEFT-BUNDLE-CRT trial. Journal: European heart journal PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41978340 Summary: Conduction system pacing has emerged as an alternative to biventricular pacing for cardiac resynchronization therapy. The LEFT-BUNDLE-CRT trial directly compared left-bundle branch area pacing to biventricular pacing. This multicenter, randomized, non-inferiority study provided a comprehensive evaluation of their comparative effectiveness in patients eligible for cardiac resynchronization therapy and left-bundle branch block. The study’s results established the non-inferiority profile of left-bundle branch area pacing against biventricular pacing for this patient population. Article 3: Mavacamten Versus Alcohol Septal Ablation in Obstructive Hypertrophic Cardiomyopathy: An Echocardiography-Derived Pressure-Volume Analysis. Journal: Circulation. Heart failure PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41969098 Summary: Obstructive hypertrophic cardiomyopathy is characterized by left ventricular outflow tract obstruction, which increases afterload and activates the Anrep response of hyperdynamic systole. This study directly compared the effects of the myosin inhibitor mavacamten to alcohol septal ablation. Researchers evaluated whether mavacamten reverses this hyperdynamic state, contrasting its impacts with the anatomic relief from alcohol septal ablation in 36 patients. The investigation’s echocardiography-derived pressure-volume analysis clarified the differential physiological effects of these two therapeutic approaches. Article 4: Device-Related Adverse Events and Outcomes in Patients With Temporary Mechanical Circulatory Support Placed at Referral Centers Versus Cardiogenic Shock Hub Centers: An Observational Analysis.

Time-Varying Data Boosts Transplant Risk Accuracy 04/14/26
Welcome to Cardiology Today – Recorded April 14, 2026. This episode summarizes 5 key cardiology studies on topics like aspirin and left bundle branch block. Key takeaway: Time-Varying Data Boosts Transplant Risk Accuracy. Article Links: Article 1: Endovascular Therapy for Post-Thrombotic Syndrome – A Randomized Trial. (The New England journal of medicine) Article 2: Cell Type-Specific Targeting of Different Smooth Muscle Cell Populations by Intersectional Genetics. (Circulation) Article 3: Timing is everything: Using time-varying binary indicators for evaluating post-transplant risk factors. (The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation) Article 4: Subclinical atrial fibrillation and the risk of heart failure: insights from ARTESiA. (European journal of heart failure) Article 5: Dyssynchronous heart failure: mitochondrial distribution and functions mirror regional workload and energy demand in a large-animal model of ventricular desynchronization. (European journal of heart failure) Full episode page: https://podcast.explainheart.com/podcast/time-varying-data-boosts-transplant-risk-accuracy-04-14-26/ Featured Articles Article 1: Endovascular Therapy for Post-Thrombotic Syndrome – A Randomized Trial. Journal: The New England journal of medicine PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41972998 Summary: This randomized trial evaluated endovascular therapy, specifically iliac-vein stent placement, for patients with moderate or severe post-thrombotic syndrome linked to iliac-vein obstruction. The study included 225 patients who received either endovascular therapy or enhanced conventional management, addressing the critical clinical issue of improving quality of life. This trial focused on whether the intervention reduced symptom severity for patients severely affected by post-thrombotic syndrome. Article 2: Cell Type-Specific Targeting of Different Smooth Muscle Cell Populations by Intersectional Genetics. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41969103 Summary: This study developed a new strategy using intersectional genetics for cell type-specific targeting of smooth muscle cell populations. This refined approach effectively overcomes limitations of existing Cre/loxP recombination systems that previously showed off-target activity outside the smooth muscle cell lineage. The new method precisely distinguishes among arterial smooth muscle cells, venous smooth muscle cells, and non-vascular smooth muscle cells. This capability is essential for characterizing the distinct roles of smooth muscle cells in various organs and diseases. Article 3: Timing is everything: Using time-varying binary indicators for evaluating post-transplant risk factors. Journal: The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41974389 Summary: This study demonstrated that incorporating a time-varying binary indicator in a Cox model correctly analyzes post-transplant risk factors. Traditional methods, which treat risk factors as fixed at the time of transplantation, produce inaccurate effect estimates due to immortal time bias. Using infection-related hospitalizations after heart transplantation as an example, this refined approach properly aligns the timing of exposure with survival follow-up. This methodology yields more credible and accurate effect estimates for risk factors emerging after transplantation. Article 4: Subclinical atrial fibrillation and the risk of heart failure: insights from ARTESiA. Journal: European journal of heart failure PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41973801 Summary: The ARTESiA (Apixaban for the Reduction of Thromboembolism in Patients with Device-Detected Subclinical Atrial Fibrillation) trial, involving 3986 patients, compared apixaban with aspirin for reducing thro

Salusin-Alpha Restores Vessels in Pulmonary Hypertension 04/13/26
Welcome to Cardiology Today – Recorded April 13, 2026. This episode summarizes 5 key cardiology studies on topics like ischemic stroke and prehospital delay. Key takeaway: Salusin-Alpha Restores Vessels in Pulmonary Hypertension. Article Links: Article 1: Salusin-α Restores Vascular Relaxation and Remodeling in Pulmonary Hypertension. (Hypertension (Dallas, Tex. : 1979)) Article 2: Endothelial Senescence Drives Deleterious Endothelial-Adipocyte Cross-Talk in Patients With Heart Failure and Type 2 Diabetes. (JACC. Basic to translational science) Article 3: Kinetics of Technetium-Labeled Cardiac Amyloid Radionuclide Imaging. (Circulation. Cardiovascular imaging) Article 4: Intracranial Hemorrhage Patterns and Outcomes in Minor Stroke: Analysis of the TEMPO-2 Trial. (Stroke) Article 5: Cost-Effectiveness of Prehospital Delay Reduction Versus Primary Stroke Prevention in US Adults With Type 2 Diabetes. (Stroke) Full episode page: https://podcast.explainheart.com/podcast/salusin-alpha-restores-vessels-in-pulmonary-hypertension-04-13-26/ Featured Articles Article 1: Salusin-α Restores Vascular Relaxation and Remodeling in Pulmonary Hypertension. Journal: Hypertension (Dallas, Tex. : 1979) PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41958393 Summary: This study demonstrated that salusin-alpha restored vascular relaxation and reversed vascular remodeling in pulmonary hypertension. Researchers found these effects by assessing pulmonary artery relaxation using isometric tension recording in isolated rat pulmonary arteries. They quantified reductions in pulmonary artery remodeling through histological morphometric analysis. The data indicated that salusin-alpha significantly alleviated the progressive increase in pulmonary arterial resistance characteristic of pulmonary hypertension. Article 2: Endothelial Senescence Drives Deleterious Endothelial-Adipocyte Cross-Talk in Patients With Heart Failure and Type 2 Diabetes. Journal: JACC. Basic to translational science PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41967191 Summary: Microvascular endothelial cells (MVECs) from subcutaneous adipose tissue of patients with type two diabetes mellitus and heart failure exhibited a senescent phenotype. These senescent cells displayed elevated senescence-associated secretory phenotype markers, reduced adenosine triphosphate production, and impaired angiogenic and proliferative capacities. When cocultured with healthy adipocytes, these senescent M. V. E. C. s drove adverse cross-talk, inducing a proinflammatory adipocyte phenotype with increased interleukin-6 expression. This research revealed how endothelial senescence contributes to chronic inflammation in this high-risk patient population. Article 3: Kinetics of Technetium-Labeled Cardiac Amyloid Radionuclide Imaging. Journal: Circulation. Cardiovascular imaging PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41961986 Summary: This study characterized the tracer kinetics of technetium-labeled bone-avid tracers used for diagnosing transthyretin cardiac amyloidosis. Researchers defined these kinetics using quantitative single-photon emission computed tomography with computed tomography in 24 subjects evaluated for the condition. The findings established the kinetic profile of these diagnostic agents. The study also addressed the use of hydroxymethylene diphosphonate as an alternative to technetium-99m pyrophosphate due to supply shortages, noting the limited comparative kinetic data available. Article 4: Intracranial Hemorrhage Patterns and Outcomes in Minor Stroke: Analysis of the TEMPO-2 Trial. Journal: Stroke PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41958392 Summary: This secondary analysis of the TEMPO-2 multicenter, randomized trial evaluated specific intracranial hemorrhage patterns and their impact on functional outcomes in patients with minor ischemic stroke. The study identified distinct predictors associated with intracranial hemorrhage within this patient population. It found that intr
