Background: Amyloidosis is a severe systemic disorder produces by the accumulation of inappropriately amyloid deposition in tissues. Cardiac involvement, as a main type of amyloidosis, has a major impact on prognosis. We describe a biopsy-proven cardiac amyloidosis in an old man with unexpected presentation.
Case Report: A 70-year-old man, with a complaint of severe weakness, lightheadedness, and lower limb paresthesia, was admitted to the emergency department. Electrocardiography revealed right bundle branch block and Trifascicular block. Echocardiography study showed a moderately increased thickness of left ventricular wall with concentric pattern as well. Laboratory investigations including serum and urine electrophoresis, and serum free light chain examination as immunofixation assay revealed that κ chains predominated over λ chains in a ratio of 3:2. Our patient with final diagnosis of amyloid light-chain (AL) amyloidosis underwent chemotherapy with melphalan combined with high-dose dexamethasone, CPHPC and monoclonal antibodies for 2 weeks.
Conclusion: It shows that rapid diagnosis of AL amyloidosis can enhance the prognosis. Applying an optimal strategy for the treatment leads to effective therapy, too.

Surgical explantation of an infected Lotus Edge valve: a case report.

Background: With the rapid expansion of transcatheter aortic valve replacement (TAVR), TAVR valve explantation is also increasing. Nevertheless, previous reports on Lotus Edge valve explantation are limited to only two reports, none of which include intraoperative videos. Therefore, we report the case of an older adult who underwent a 2-year-old Lotus Edge valve explantation, after developing prosthetic valve endocarditis (PVE) and aortic annular abscess, with a strong indication for a TAVR explantation and surgical aortic valve replacement (AVR).

Conduction blocks complicating ST(ST-segment)-elevation myocardial infarction are associated with increased morbidity and mortality. Research indicates that anterior and inferior wall myocardial infarction were the most encountered causes of blocks but with conflicting results. However, patterns of conduction blocks have not been widely established in our population.

Background: While the use of immunotherapy has revolutionised the treatment of various cancers, it is often associated with a myriad of immune-related adverse effects.
Case Presentation: In this article, we report a rare case of durvalumab-induced triple-M syndrome in a 69-year-old woman with stage III lung adenocarcinoma. She was admitted with profound generalised muscle weakness, myalgia, and exertional breathlessness, about a week into her second cycle of durvalumab, an immune checkpoint inhibitor.
Predictors of permanent pacemaker implantation following transcatheter aortic valve replacement-the search is still on!

Several anatomical, demographic, clinical, electrocardiographic, procedural, and valve-related variables can be used to predict the probability of developing conduction abnormalities after transcatheter aortic valve replacement (TAVR) that necessitate permanent pacemaker (PPM) implantation. These variables include calcifications around the device landing zone and in the mitral annulus; pre-existing electrocardiographic abnormalities such as left and right bundle branch blocks (BBB), first- and second-degree atrioventricular blocks, as well as bifascicular and trifascicular blocks; male sex; diabetes mellitus (DM); hypertension; history of atrial fibrillation; renal failure; dementia; and use of self-expanding valves. The current study supports existing literature by demonstrating that type 2 DM and baseline right BBB are significant predictors of PPM implantation post-TAVR.

In clinical practice, the accurate diagnosis of the causes of syncope is often challenging and demanding. Moreover, certain rare electrocardiographic phenomena may complicate the diagnostic workup, leading to imprecise diagnoses. The present study briefly describes the case of an 82-year-old male patient with ischemic cardiomyopathy who suffered syncopal episodes in the setting of trifascicular block.
