... occurring after bariatric surgery. We report a case of recurrent syncope due to high-grade atrioventricular block (AVB) after gastric sleeve surgery. Case summary A 32-year-old woman with a background of morbid obesity and diet-controlled type 2 diabetes mellitus, presented with recurrent post-prandial...

... for the management of patients with dual atrioventricular valve regurgitation (DAVR) undergoing transcatheter aortic valve replacement (TAVR), and existing data on its clinical impact remain absent. Therefore, we aimed to provide detailed insights into the impact of DAVR on outcomes after TAVR, with the potential...

... present with symptoms like arrhythmias, heart failure, or cardiogenic shock. Case summary A 50-year-old Caucasian construction worker was admitted to our emergency department with a new-onset third-degree atrioventricular (AV) block following a traumatic blunt chest injury at work. The arrhythmia...

... considering the patient’s fragile haemodynamic state. Pacing studies indicated that sRV pacing was superior to left ventricular septal pacing, as it reduced the QRS duration and improved RV synchrony. Following successful sRV septal lead implantation and atrioventricular delay (AVD) optimization, HF symptoms...

This stresses the need for further research to confirm their pathophysiological basis and develop clearer management strategies.

... are asymptomatic and have a benign course, there are several reports of mitral valve dysfunction, stroke, and myocardial infarction. However, few reports have been published on conduction disturbances. Case summary We encountered a case of an atrioventricular block, which is a rarely reported complication...

... Aims To investigate the distribution of left atrioventricular coupling index (LACI) among patients with heart failure and left ventricular ejection fraction (LVEF) < 50% and to explore its association with the combined endpoint of all-cause death or HF hospitalization at long-term follow-up...

... echocardiography and diagnosed a common atrium, unbalanced complete AVSD with hypoplastic LV, patent ductus arteriosus, and moderate atrioventricular valve (AVV) regurgitation ( Figure 2 , Supplemental file 1 ). The diameter of the ventricular septal defect (VSD) was measured as 11 mm (upon later...

Abstract Background Accessory pathways (AP) are associated with an increased risk of atrioventricular reentry tachycardia (AVRT), presenting as a wide QRS...

... replacement (SAVR) poses unacceptably high operative risk, some of these patients are ultimately forced to undergo open surgery when TAVI is complicated by infective endocarditis (IE). To our knowledge, there have been no reports of cases with periannular extension of IE and atrioventricular block...

... and optimal pacing sites have not been systematically studied. We performed CRT for ccTGA with a complete atrioventricular block (CAVB) by pacing the dorsal site of right ventricular inflow (dRVI) and anterior RV outflow tract (aRVOT). Case summary We examined a man aged 19 with ccTGA (S.L.L) and Ebstein...

... rhythm during long-term follow-up is still limited. Atrioventricular node ablation (AVNA) has returned as a valuable treatment option given the recent developments in cardiac pacing. With the advent of conduction system pacing, AVNA has seen a revival where pacing-induced cardiomyopathy after AVNA...

.../ ), which permits unrestricted reuse, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract Background One of the most important and relatively frequent complications of aortic valve replacement is atrioventricular block. It typically occurs by direct injury...

... Sarcoidosis is a rare disease, and cardiac involvement is seen in the minority of patients. The clinical symptoms depend on the location of the noncaseating granulomas in the heart and vary from asymptomatic to atrioventricular (AV) conduction block, ventricular arrhythmia, heart failure, and sudden cardiac...

... female, with a background of poorly rate-controlled atrial fibrillation, presented with worsening dyspnoea. She had recently undergone single-chamber pacemaker insertion prior to an atrioventricular nodal (AVN) ablation, owing to failure in achieving successful CRT coronary sinus lead placement. She had...
