Left atrial mitral valve chordae: An important congenital abnormality mimicking endocarditis on transthoracic echocardiography-Case report.

A 59-year-old male was incidentally diagnosed with a left atrial mitral valve chordae involving the junction of the A1 and A2 mitral valve leaflets and resulting in moderate mitral regurgitation. The recognition of this extremely rare congenital malformation prevented over diagnosis and overtreatment.

Levosimendan and Continuous Outpatient Support With Inotropes in Patients With Advanced Heart Failure: A Single-Centre Descriptive Study.

ABSTRACT: To describe the use of levosimendan in a quaternary referral center with a dedicated heart failure service and compare its efficacy and safety to continuous outpatient support with inotropes (COSI) among patients with advanced heart failure (AHF) who require bridge-to-decision (BTD) or bridge-to-transplant (BTT) therapy. This study was a retrospective, single-center, descriptive study of patients with AHF who received either a single levosimendan infusion or COSI between 2018 and 2021. A total of 23 patients received a levosimendan infusion, and 14 were started on COSI. Three indications for levosimendan were identified: (1) to facilitate weaning of continuous inotropes, (2) to augment diuresis in cardiorenal syndrome, and (3) as first-line therapy for cardiogenic shock in selected patients. Eighty-three percent (19 of 23) of patients who received levosimendan survived to discharge, and there were few clinically significant adverse events. Overall survival at 12 months among patients who received levosimendan was 74%. No statistically significant difference in survival was observed at 12 months (P = 0.68) or beyond (P = 0.63) between patients who received levosimendan and were discharged with a plan for BTD or BTT and those who received COSI. Levosimendan is a safe and effective short-term therapy in AHF and offers comparable long-term survival to COSI in patients who require BTD or BTT therapy.

Prescription trends and costs of diabetes medications in Australia between 2003 and 2019: an analysis and review of the literature.

BACKGROUND: Since the turn of the century, the prevalence of diabetes mellitus in Australia has increased, primarily due to rising rates of Type 2 diabetes. Simultaneously, the landscape of diabetes medications has evolved significantly. The change in prescribing trends and public spending on diabetes medications within Australia during this period are not well defined. AIMS: To establish the frequency and cost of dispensed diabetes medications in the Australian public healthcare system between 2003 and 2019. METHODS: We performed a longitudinal nationwide observational study using data obtained from the Pharmaceutical Benefits Scheme (PBS) and Medicare Benefits Schedule websites, which contain information on frequency and spending of diabetes medications dispensed in Australia. RESULTS: The total number of PBS-subsidised prescriptions dispensed for diabetes increased from 5 218 690 in 2003 to 12 188 568 in 2019, and spending increased from $117 241 031 to $598 904 983. Of the non-insulin agents, metformin was consistently the most frequently dispensed agent, with a rapid growth in metformin combination tablets. Dispensation of sulphonylureas and thiazolidinediones have declined, with a simultaneous increase in dipeptidyl peptidase-4 inhibitors, sodium-glucose co-transporter 2 inhibitors and glucagon-like peptide-1 receptor agonists. CONCLUSIONS: Our data show a large growth in the use of diabetes medications between 2003 and 2019. The rapid growth in dispensing of drugs with proven cardiovascular and renal benefits reflect the evolving approach of diabetes treatment, from a historical approach targeting glycaemic control alone, to a modern individualised approach targeting specific co-morbidities.

Nivolumab-induced myocarditis complicated by complete atrioventricular block in a patient with metastatic non-small cell lung cancer.

We report a case of a 74-year-old man who developed myocarditis complicated by atrioventricular (AV) block following two doses of nivolumab for the treatment of non-small cell lung cancer. A diagnosis of drug-induced acute myocarditis with complete AV block was considered on the basis of elevated troponin, new onset left ventricular (LV) systolic dysfunction, absence of acute myocardial infarction and some findings suggestive of myocarditis on cardiac magnetic resonance. The patient was commenced on glucocorticoids, perindopril and carvedilol. AV block and LV dysfunction persisted despite 2 weeks of treatment. He ultimately became hypotensive which prompted an implantation of a cardiac resynchronisation therapy pacemaker. Follow-up echocardiogram at 6 weeks showed resolution of LV systolic dysfunction. However, he continued to have AV block.
