Longitudinal patient registries generate important evidence for advancing clinical care and the regulatory evaluation of health-care products. Most national registries rely on data collected as part of routine clinical encounters, an approach that does not capture real-world, patient-centred outcomes, such as physical activity, fatigue, ability to do daily tasks, and other indicators of quality of life. Digital health technologies that obtain such real-world data could greatly enhance patient registries but unresolved challenges have so far prevented their broad adoption.

Introduction: Transcatheter mitral valve-in-valve replacement (TMVR ViV) is becoming a favorable, less invasive procedure among high-risk patients to manage mitral valve dysfunction. We aimed to investigate the trends of the predictors and outcomes of the procedure.

Methods: The national inpatient sample databases of 2016-2020 were analyzed using STATA 17 software and ICD-10 codes for TMVR ViV, with stratification for mitral stenosis (MS) or Mitral regurgitation (MR) as etiology for prosthetic valve dysfunction.

Cardiovascular complications of Brucellosis are not common and affecting less than 2% of cases. In clinical practice, endocarditis is the most frequent cardiovascular complication and is responsible for most of the brucellosis-related mortality cases and usually diagnosed lately in the course of the disease with mostly aorta valve involvement. In this case report, we present the case of a 27-year-old woman who was admitted to the hospital with fever, sudden onset right side hemiparesis, and horizontal gaze palsy.

Brain vs Heart: Prioritizing Treatment in Left-Side Infective Endocarditis With Neurologic Complications.

JACC Case Rep

November 2024

Department of Cardiothoracic Surgery, School for Cardiovascular Disease, Maastricht University, Maastricht, the Netherlands.

A paradigmatic case is presented of subarachnoid hemorrhage as the initial sign of bacterial endocarditis on a mechanical cardiac prosthesis, in the absence of symptoms and echocardiographic evidence of infective endocarditis and vegetation. The presentation emphasizes the need to pursue a diagnostic workup for bacterial endocarditis whenever a patient with a mechanical prosthesis presents to the emergency department with focal neurologic signs. In addition, it highlights the potential use of second-level diagnostic tools to assess the extent of abscess presence and lesion extension to other cardiac structures for proper surgical planning.

J Thorac Cardiovasc Surg

November 2024

Division of Cardiothoracic Surgery, Mount Sinai Saint Luke's, New York, NY.

Objective: To evaluate the midterm survival, clinical, and hemodynamic outcomes of the On-X mechanical mitral valve, based on the 5-year results of the Prospective Randomized On-X Anticoagulation Clinical Trial (PROACT).

Method: PROACT Mitral was a multicenter study evaluating 401 patients who underwent mitral valve replacement (MVR) with either Standard or Conform-X On-X mitral valves, comparing low-dose and standard-dose warfarin. Here we report prespecified secondary outcomes of survival, New York Heart Association (NYHA) functional classification, and valve hemodynamics as assessed by core lab-adjudicated echocardiography at 1, 3, and 5 years in the pooled population.

  • Patients with chronic kidney disease (CKD) on renal replacement therapy (RRT) face a high risk of infections from cardiovascular implantable electronic devices (CIED), but device extraction, the usual way to manage these infections, is often avoided due to high procedural risks.
  • A study analyzed data from CKD patients with CIED infections, finding that 30% underwent device extraction, which significantly improved one-year survival rates (59.2% vs. 48.8% for no extraction).
  • Despite the survival benefits, the low rate of device extraction among these patients highlights a need for better management strategies in this high-risk group.

  • Tricuspid valve pathology is common and presents challenges for mechanical tricuspid valve replacement, particularly when implanting a permanent pacemaker due to risks like valve damage and lead fractures.
  • Epicardial leads, while an option, are not ideal for patients with past thoracotomies due to surgical requirements.
  • This case report showcases successful left ventricular (LV) pacing through the coronary sinus in a 30-year-old woman, proving it to be a safe and effective alternative method for pacemaker implantation without additional invasive procedures.

  • Transcatheter closure of paravalvular leaks (PVL) is a viable treatment for high-risk patients, yet limited research exists on its effectiveness using Amplatzer devices in Japanese patients with mitral PVL.
  • A study involving 12 patients (average age 78) showed successful closure procedures were performed, with a reduction in PVL severity and no major complications reported within 30 days.
  • One year later, an all-cause mortality rate of 16.7% was noted, with 25% of patients needing further intervention due to symptom recurrence, indicating the treatment's potential but also the need for monitoring.

This novel case documents the successful use of transcatheter aortic valve implantation to treat severe aortic insufficiency arising from aortic root dissection following the repair of an ascending aortic aneurysm in a 75-year-old female patient. After she presented with symptoms of congestive heart failure, investigation revealed new severe aortic insufficiency and an acute aortic dissection. Given the prohibitive risks of reoperation, a self-expanding 27-mm Portico (St Jude Medical) prosthetic aortic valve was deployed, resulting in substantial clinical improvement without procedural complications.

Article Synopsis
  • Atrial fibrillation (AF) is common and usually treated with oral anticoagulants to prevent strokes, where direct oral anticoagulants (DOAC) are more effective in reducing certain types of bleeding compared to vitamin K antagonists (VKA).
  • The INVICTUS study showed that the DOAC rivaroxaban was not superior to VKA in preventing serious complications like stroke for patients with rheumatic valvular AF, leading to higher death and drug discontinuation rates in the DOAC group.
  • While VKAs remain the standard treatment for patients with moderate-to-severe mitral stenosis and prosthetic valves, new factor XI inhibitors show promise in reducing bleeding risks and are currently undergoing further testing in AF and

Article Synopsis
  • - The study investigates how well deep-learning (DL) models can analyze electrocardiograms (ECGs) to predict changes in the left ventricle related to significant aortic regurgitation (AR), which has been challenging to identify in the past.
  • - Researchers collected data from 573 patients and used a ResNet-based model to correlate ECG readings with various left ventricular parameters, achieving promising scores in distinguishing levels of left ventricular dysfunction.
  • - The findings suggest that using DL models on ECGs could improve the detection of left ventricular issues and potentially reduce the need for additional echocardiography, especially in situations where access to such tests is limited.
