Percutaneous closure of left ventricular pseudoaneurysm in a patient with concomitant true left ventricular aneurysm.

BACKGROUND: Left ventricular aneurysms (LVA) are serious complications of myocardial infarction, being divided into true and false type. The false one-pseudoaneurysm (PA), is a life-threatening condition that requires urgent treatment due to the high risk of rupture. CASE PRESENTATION: An 84-year-old female presented with progressive heart failure symptoms. Investigation showed a small true LVA and a large PA. Open surgical repair was ruled out as Euroscore and Society of Thoracic Surgeons (STS) score were 42.80% and 39.97%, respectively. After discussion at our Heart Team meeting, percutaneous approach was found to be the best option. Guided by transesophageal echocardiography, we used an interventricular septal defect occluder to close the gap between the LV and the PA. Control ventriculography showed full closure of the gap, with no residual flow to the PA cavity. The patient was discharged from the hospital on the fifth postoperative day and has remained asymptomatic since then. CONCLUSION: Percutaneous approach proved to be a safe and effective modality to treat LV PA. The device implanted achieved the goal of blocking blood flow through the communication between LV and the PA.

Wrapping of ascending aortic aneurysm with supra-aortic debranching and endovascular repair for aortic arch aneurysm and ruptured descending thoracic aortic aneurysm.

We report a case of a hybrid surgical treatment of a 71-year-old fragile female with severe chronic obstructive pulmonary disease with a 5-year history of progressive back pain and diagnosis of descending thoracic aorta aneurysm (DTAA), but refused operation at first. Since the patient presented with an acute expanding painful pulsatile mass due to a ruptured DTAA contained by the subcutaneous tissue and had a high-risk surgical profile, we agreed that the simplest urgent operation should be performed. Cardiopulmonary bypass with or without deep hypothermic circulatory arrest was ruled out as an option. The initial approach would be permanent bypasses to the supra-aortic trunks and endovascular repair of the ruptured DTAA, but we ran into a problem: the absence of suitable diameter in the ascending aorta to land the prosthesis-zone 0. To overcome this obstacle, we opted to perform a diameter reduction of the ascending aorta by wrapping it with a Dacron tube to create a neck where we could land the endovascular prosthesis. Following this step bypasses from the proximal ascending aorta to the brachiocephalic artery, left common carotid artery and left subclavian artery were created. Since we gained ground to act in zone 0, the first endoprosthesis was landed in the wrapped zone and the aortic arch-from zone 0 to zone 3. The second and third endoprostheses covered the ruptured DTAA above the celiac trunk-zones 4 and 5. Good positioning of the endoprostheses was achieved and we attained procedural success.
