This may be of particular concern with rotary biventricular support (BiVAD) where the native, flow balancing Starling response is diminished in both ventricles. The reliability of sensor and sensorless\u2010based control systems which aim to control VAD flow based on preload has limitations, and, thus, an alternative solution is desired. This study introduces a compliant inflow cannula (CIC) which could improve the preload sensitivity of a rotary VAD by passively altering VAD flow depending on preload. To evaluate the design, both the CIC and a standard rigid inflow cannula were inserted into a mock circulation loop to enable biventricular heart failure support using configurations of atrial and ventricular inflow, and arterial outflow cannulation. A range of left (LVAD) and right VAD (RVAD) rotational speeds were tested as well as step changes in systemic\/pulmonary vascular resistance to alter relative preloads, with resulting flow rates recorded. Simulated suction events were observed, particularly at higher VAD speeds, during support with the rigid inflow cannula, while the CIC prevented suction events under all circumstances. The compliant section passively restricted its internal diameter as preload was reduced, which increased the VAD circuit resistance and thus reduced VAD flow. Therefore, a CIC could potentially be used as a passive control system to prevent suction events in rotary left, right, and biventricular support.<\/jats:p>","DOI":"10.1111\/j.1525-1594.2012.01504.x","type":"journal-article","created":{"date-parts":[[2012,8,6]],"date-time":"2012-08-06T09:08:40Z","timestamp":1344244120000},"page":"683-690","source":"Crossref","is-referenced-by-count":15,"title":["Passive Control of a Biventricular Assist Device With Compliant Inflow Cannulae"],"prefix":"10.1111","volume":"36","author":[{"given":"Shaun David","family":"Gregory","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark John","family":"Pearcy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Timms","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,8,6]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.med.032309.063018"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8191.2008.00606.x"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2009.11.026"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1510\/icvts.2006.128322"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.healun.2009.11.599"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2008.09.021"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10439-011-0348-8"},{"key":"e_1_2_7_9_2","volume-title":"Textbook of Medical Physiology","author":"Guyton AC","year":"2005"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1927.sp002355"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.2345\/0899-8205(2007)41[385:VDATAH]2.0.CO;2"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1525-1594.2010.01168.x"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-1594.2000.06589.x"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-1594.2002.07123.x"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAT.0b013e31815b2d1e"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAT.0b013e318142bfce"},{"key":"e_1_2_7_17_2","unstructured":"YuYC PorterJ.Mathematical modeling of ventricular suction induced by a rotary ventricular assist device.Proceedings of the 2006 American Control Conference.2006.
