Ventricular distention may occur when blood returns to the heart while the heart is arrested or fibrillating – a common and detrimental occurrence. While the right ventricle is kept safe from harm during cardiopulmonary bypass by venous cannulation, the left ventricle can become distended from blood leakage,¹ requiring venting.
Many left vents on the market today have a standard closed distal tip and utilize a rigid stylet to assist in placement. Some surgeons have commented that the closed tip design does not provide optimal drainage for the full length of the left ventricle and the stiff tip/stylet combination can cause tissue trauma during insertion and manipulation.
The PEAK Left Heart Vent Cannula from Surge Cardiovascular helps solve these design challenges.
The Surge Cardiovascular PEAK Left Heart Vent Cannula’s design provides the surgeon with improved insertion and navigation control. The PEAK Left Vent features a soft radius, polymer-coated and shapeable stylet to assist in positioning the cannula in the left ventricle. Surgeons can be confident that the atraumatic insertion will protect the delicate cardiac cavities from perforation.
To improve blood drainage, the PEAK Left Vent has been designed with 24-elliptical side holes and an open distal tip. Depth indicators aid in precise positioning and the product is available in three widths to meet the patient’s needs – 16, 18, and 20 French.
