Surgical Repair for Anterior and Inferior Ventricular Aneurysms
Alnajar A, Loor G, Letsou GV. Surgical Repair for Anterior and Inferior Ventricular Aneurysms. July 2019. doi:10.25373/ctsnet.8984282.
Objectives
Left ventricular aneurysm repair has been performed for nearly four decades, yet no surgical approach has been identified as the most effective. The authors describe their approach to repairing anterior and inferior aneurysms.
Methods
Figure 1A.
The surgical repair is illustrated in two patients, a 67-year-old woman and a 51-year-old man, with a beating and an arrested heart. For either type of aneurysm, the authors start by making an incision through the aneurysm and removing the mural thrombus (Figure 1A). Then they sew a Dacron patch into place and use a second layer of hemostatic suture that goes through double Teflon strips outside of the ventricle (Figure 1B). They add a third reinforcing suture layer over the entire repaired area (Figure 1C), which completes the repair (Figure 1D).
Results
The repair was hemostatic. Cardiac contractility was well preserved. Both patients were alive and well with normal cardiac function at 32 and 16 postoperative months, respectively.
Conclusion
This method of left ventricular aneurysm repair provided satisfactory results. It appears to be a good technique for repair of both anterior and inferior wall aneurysms, having no short- or mid-term complications.
