Cardiomyopathy V: Interprofessional Care01:29

Cardiomyopathy V: Interprofessional Care

56
Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiac Catheterization III: Left Heart Catheterization

250
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Cardiac Catheterization II: Right Heart Catheterization

225
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Cardiomyopathy II: Dilated Cardiomyopathy01:30

Cardiomyopathy II: Dilated Cardiomyopathy

48
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Aortic Regurgitation III: Medical Management01:25

Aortic Regurgitation III: Medical Management

59
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Mechanical Circulatory Support

Background:

  • Long-term left ventricular assist device (LVAD) patients have high risks for open cardiac reoperation.
  • Interventional approaches are crucial for managing LVAD-associated complications in this population.

Purpose of the Study:

  • To evaluate the feasibility and safety of interventional treatments for LVAD complications.
  • To assess outcomes of transcatheter aortic valve replacement (TAVR) and outflow graft interventions (OGI) in LVAD patients.

Main Methods:

  • Retrospective analysis of 871 LVAD patients from January 2016 to December 2020.
  • Evaluation of 76 patients who underwent interventional procedures (17 TAVR, 61 OGI) for LVAD complications.

Main Results:

  • TAVR improved symptoms in patients with severe aortic regurgitation.
  • OGI successfully restored LVAD flow, unloaded the left ventricle, and improved right heart function (p < 0.001).
  • Complications included right heart failure, heart block, bleeding, and in-hospital mortality (9.6% after OGI).

Conclusions:

  • Interventional procedures are a feasible and safe treatment option for LVAD-associated complications.
  • TAVR and OGI demonstrate significant benefits in managing specific LVAD-related issues.
