Challenges in cannulation of left ventricular apex for temporary circulatory support: a case report.

Apical cannulation of a left ventricle for temporary support is still challenging, especially in case of prolonged support due to donor organ shortage. Traditional cannulation techniques with the cannula being directly inserted into the left ventricle cavity are technically easy, but prone to hemorrhage during circulatory support, unsafe for a prolonged support (over than 30 days) and limits the possibility to ambulate patient due to risk for cannula dislocation and related life-threatening bleeding. We describe a case of temporary left ventricular assist device placement in a 59-year-old male patient being on veno-arterial extracorporeal membrane oxygenation support secondary to acute myocardial infarction. We present a very simple technique to secure insertion of an apical left ventricular cannula using patch of soft Teflon felt. Handmade created apical soft Teflon cuff is than fixed using twelve 4/0 prolene sutures supported with pledgets. This gives better fixation to apical myocardium (especially in case of fragile tissue after acute infarction) and secure intracavitary length of inflow cannula in a controlled mode, thus better than purse-string sutures only. Using anti-adhesive membrane, further dissection during heart transplant procedure was uneventful. This technique allowed safe circulatory support and patient ambulation in the ward during 85 days until heart transplantation.
