Percutaneous Cardiac Chambers and Pulmonary Artery Aspiration.

Purpose Of Review: The clinical guidelines and current practice in the field of removable cardiovascular pathologies are not aligned and are in fluctuation. The purpose of this review manuscript is to propose adjustments and forecast changes in clinical practice in this field ahead of irrefutable evidence. Percutaneous aspiration devices may be used in case of pulmonary embolism, endocarditis, cardiac thrombi, and tumors. The rationale of treatment includes prevention of emboli, endocarditis debulking and modification, sampling of tissue, and salvage therapy. We are describing the contemporary treatments that are occurring in practice outside and above guidelines.

Recent Findings: The current standard therapy for the above-mentioned entities is not supported by robust data. Moreover, evidence suggesting priority for the use of percutaneous aspiration devices as first-line therapy-before turning to or in lieu of surgery or thrombolysis-continues to accumulate. However, guidelines still mention percutaneous aspiration only as an alternative to standard treatment. In the current review, we discuss the pathophysiology that supports percutaneous cardiac and pulmonary artery aspiration, the commonly used devices for that purpose, their clinical evidence, and accordingly propose a modified approach to patient management. In addition, this review highlights fluid dynamic principles important in matter extraction in order to better define the utility of catheter-based technologies in different cardiovascular territories. The target diseases encompassed in this review are pulmonary embolism, cardiac masses, and vegetations.
