Treatment of Refractory Monoclonal Immunoglobulin Deposition Disease With BCMA Bispecific Antibody.

Monoclonal immunoglobulin deposition disease (MIDD) is characterized by deposits of intact monoclonal immunoglobulin protein, most commonly in the kidney, but other organs such as the heart can be involved. Patients are treated with plasma cell-directed therapies. Here we describe the first reported case of a patient with refractory MIDD with renal and cardiac involvement who was successfully treated with a BCMA-drected therapy.

Acute Cardiorenal Syndrome: An Update.

The complex dynamic pathophysiological interplay between the heart and kidney causes a vicious cycle of worsening renal and/or cardiovascular function. Acute decompensated heart failure causing worsening renal function defines Type 1 cardiorenal syndrome (CRS). Altered hemodynamics coupled with a multitude of nonhemodynamic factors namely pathological activation of the renin angiotensin aldosterone system and systemic inflammatory pathways mechanistically incite CRS type 1.

Impact of Acute and Chronic Kidney Disease on Heart Failure Hospitalizations After Acute Myocardial Infarction.

Very few studies evaluated the impact of acute kidney injury (AKI) and chronic kidney disease (CKD) on heart failure (HF) hospitalization risk following an acute myocardial infarction (AMI). For this retrospective cohort analysis, we identified adult AMI survivors from January to June 2014 from the United States Nationwide Readmissions Database. Outcomes were a 6-month HF, fatal HF, composite of HF during the AMI or a 6-month HF, and a composite of 6-month HF or death during a non-HF-related admission.

Association of right ventricular dysfunction and pulmonary hypertension with adverse 30-day outcomes in COVID-19 patients.

Background: Cardiac manifestations in COVID-19 are multifactorial and are associated with increased mortality. The clinical utility and prognostic value of echocardiography in COVID-19 inpatients is not clearly defined. We aim to identify echocardiographic parameters that are associated with 30-day clinical outcomes secondary to COVID-19 hospitalization.

The Convergent Atrial Fibrillation Ablation Procedure: Evolution of a Multidisciplinary Approach to Atrial Fibrillation Management.

The treatment of AF has evolved over the past decade with increasing use of catheter ablation in patients refractory to medical therapy. While pulmonary vein isolation using endocardial catheter ablation has been successful in paroxysmal AF, the results have been more controversial in patients with long-standing persistent AF where extrapulmonary venous foci are increasingly recognised in the initiation and maintenance of AF. Hybrid ablation is the integration of minimally invasive epicardial ablation with endocardial catheter ablation, and has been increasingly used in this population with better results.

Mitraclip Plus Medical Therapy Versus Medical Therapy Alone for Functional Mitral Regurgitation: A Meta-Analysis.

Introduction: The purpose of this meta-analysis is to compare the efficacy of MitraClip plus medical therapy versus medical therapy alone in patients with functional mitral regurgitation (FMR). FMR caused by left ventricular dysfunction is associated with poor prognosis. Whether MitraClip improves clinical outcomes in this patient population remains controversial.

Transcatheter aortic valve replacement versus surgical aortic valve replacement in low-surgical-risk patients: An updated meta-analysis.

Objective: The purpose of this meta-analysis is to compare the safety and efficacy of transcatheter aortic-valve replacement (TAVR) to surgical aortic valve replacement (SAVR) in low-surgical-risk patients.

Background: TAVR is proven to be safe and effective in patients with high- and intermediate-risk aortic stenosis. However, there is limited data on the safety and efficacy of TAVR in patients with low surgical risk.

A 66-Year-Old Female with Apical Hypertrophic Cardiomyopathy Presenting with Hypertensive Crises and Type 2 Myocardial Infarction and a Normal Coronary Angiogram.

A 66-year-old female presented to the emergency room with an episode of chest pain that lasted for a few minutes before resolving spontaneously. Electrocardiogram showed a left bundle branch block, left ventricular hypertrophy, and T wave inversions in the lateral leads. Initial cardiac troponin level was 0.

The effect of vasodilator β-blockers on renal function in hypertensive patients.

Background: Not only is there a limited number of studies on the effects of vasodilator β-blocker (VBB) therapy on kidney function - specifically, glomerular filtration rate (GFR), serum creatinine (sCr) and proteinuria - but of those that have been reported, the results are mixed. This meta-analysis seeks to assess the efficacy of VBBs on selected renal parameters in hypertensive patients.

Methods: We conducted a meta-analysis of any prospective trial that provided both baseline and follow-up of at least 4 weeks of VBB therapy - carvedilol, labetalol, dilevalol, nebivolol and celiprolol in patients with hypertension.

A Rare Case of Renal Infarct due to Noncompaction Cardiomyopathy: A Case Report and Literature Review.

Left ventricular noncompaction cardiomyopathy is a rare myocardial disorder which results from failure of left ventricle to compact in embryogenesis. We present a case of a 53-year-old female who came because of abdominal pain and was found to have renal infarct secondary to noncompaction cardiomyopathy.
