Venous Thrombosis III: Interprofessional Care

22
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Cardiac Catheterization III: Left Heart Catheterization

207
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

44
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Summary
This summary is machine-generated.

Endoscopic transmitral left ventricular (LV) thrombectomy offers a safe, minimally invasive option for removing LV thrombi. This technique reduces myocardial trauma and speeds recovery in selected patients with impaired LV function.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Minimally Invasive Procedures

Background:

  • Left ventricular (LV) thrombosis is a serious complication in patients with impaired LV function, often following myocardial infarction or dilated cardiomyopathy.
  • Anticoagulation is standard, but surgical thrombectomy is necessary for large, mobile, or refractory thrombi.

Purpose of the Study:

  • To evaluate the safety and efficacy of endoscopic transmitral LV thrombectomy.
  • To compare different surgical approaches for LV thrombectomy.

Main Methods:

  • A case-based review of 4 patients undergoing endoscopic transmitral LV thrombectomy via right thoracotomy.
  • A structured literature review comparing transmitral, transaortic, and transventricular approaches.

Main Results:

  • Endoscopic transmitral thrombectomy allowed precise thrombus removal without ventriculotomy in all patients.
  • All patients experienced favorable recovery with no major perioperative complications.
  • One case highlighted the need for intraoperative imaging due to absent thrombus.

Conclusions:

  • Endoscopic transmitral thrombectomy is a feasible and safe minimally invasive strategy.
  • This approach reduces myocardial trauma and shortens recovery times for selected patients.
  • Evidence supports minimally invasive techniques for managing LV thrombosis.
