“…4 More recently, Fatullayev and associates described a method without the use of synthetic material, partially reconstructing the ventricular wall followed by LVAD implantation (HeartWare device) onto the remaining part of the apical wall. 5 We believe this may provide a more stable and hemostatic surgical option.…”

“…Left ventricular assist device implantation in patients with left ventricle aneurysm is rare and not frequently found in the literature. [3][4][5] In our patient, a decision was made to implant the HVAD system with simultaneous ventricular reconstruction. Thrombectomy without ventricular reconstruction could result in a potential endocardial surface amenable to newly generated thrombus with a resultant increased risk of a cerebrovascular event or pump thrombosis.…”

Left ventricular assist devices (LVADs) extend survival of patients with end-stage heart failure as a bridge to transplant or for destination therapy. However, implant of these devices may be challenging, especially in cases of a left ventricular aneurysm involving the left ventricular apical wall. In this report, we describe a symptomatic patient with ischemic cardiomyopathy and a large left ventricular anterior aneurysm treated by reco nstruction of the left ventricle and simultaneous implant of the HeartWare LVAD system (HVAD; HeartWare International, Inc., Framingham, MA, USA). Key words: Left ventricular aneurysm, LVAD, Myocardial infarction Case ReportA 62-year-old male patient was referred to our center 26 days after acute myocardial infarction with ischemic cardiomyopathy and New York Heart Association functional class IV heart failure. Echocardiography revealed left ventricular ejection fraction of 12% and a large left ventricular aneurysm (4.0 × 3.5 × 3.0 cm). Left ventricular apical wall thickness was 4.0 mm on echocardiography. Cardiac catheterization was performed; pulmonary vascular resistance was 6 mm Hg·min -1 ·L -1 , and transpulmonary pressure gradient was 18 mm Hg. Therefore, the patient was not a candidate for heart transplant. Left ventricular assist device implantation with surgical ventricular reconstruction was decided due to the patient's deteriorating clinical situation, despite maximal medical therapy.After median sternotomy, cardiopulmonary bypass was established via aortocaval cannulation. A large aneurysm involving the anterior and lateral wall of the heart was encountered (Figure 1). Aneurysm resection with linear reconstruction was performed by a longitudinal incision parallel to the left anterior descending artery with subendocardial thrombectomy, without cross-clamp and cardioplegia, on the beating heart. Resection was extended to the anterior and lateral left ventricular wall, leaving behind approximately 4 cm of apical wall to implant the pump. The HVAD system was implanted using a standard technique as described in the instructions for use (Figure 2

“…Major advantages of a concomitant EVPP during LVAD implantation were already described [12][13][14] . Despite different reported techniques, prevention of thromboembolism by removal of thrombotic material from the former apex and more stable placement of the pump with coaxial and midventricular positioning of the inflow cannula towards the mitral valve are considered to be facilitated by EVPP.…”

Objective Left ventricular assist device (LVAD) implantation with concomitant Dor plasty is only reported anecdotally. We herein aimed to describe our experience with LVAD and concomitant Dor procedures and describe long-term outcomes of this special subset of heart failure patients. Methods Between January/2010 and December/2018, 144 patients received LVAD therapy at our institution. Of those, five patients (80% male, 60.4±7.2 years) presented with an apical aneurysm and received concomitant Dor plasty. Apical aneurysms presented diameter between 75 and 98 mm, with one impending rupture. Results Procedural success was achieved in all patients. No unplanned right ventricular assist device implantation occurred. Furthermore, no acute 30-day mortality was seen. In follow-up, one patient was lost due to intentional disconnection of the driveline. One patient underwent heart transplantation on postoperative day 630. The remaining three patients are still on device with sufficient flow; pump thromboses were successfully managed by lysis therapy in one patient. Conclusion LVAD implantation with concomitant Dor procedure is feasible, safe, and occasionally performed in patients with ischemic cardiomyopathy. Major advantages are prevention of thromboembolism and facilitation of LVAD placement by improving pump stability and warranting midventricular, coaxial alignment of the inflow cannula. In long-term follow-up, no adverse event associated with Dor plasty was observed.

We presented surgical treatment of three patients indicated for implantation of a permanent mechanical circulatory support device and with the associated left ventricular aneurysms. In order to evade the left ventricular rupture, adverse thromboembolic events and provide safe implantation of the inflow cannula, LVAD HM3 implantation together with the reconstruction of the left ventricular aneurysmal wall was performed in two patients. Regarding the third patient, LVAD implantation upon the reconstruction of the left ventricular wall was abandoned because there was no safe location for placement of the inflow cannula.
