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.

Post-transplant lymphoproliferative disease presenting as a mass in the left ventricle in a heart transplant recipient at long-term follow-up.

Neoplasms are among the most common solid-organ transplant complications, occurring in 11.7% of all transplant recipients and in 6% to 15% of heart transplant recipients, according to early studies. The skin and lips are the most common sites for neoplasms, but they also appear in the setting of post-transplant lymphoproliferative disease. Post-transplant lymphoproliferative disease (PTLD) is one of the most serious complications of long-term immunosuppression after transplantation. Herein we report the case of a 53-year-old man who underwent orthotopic heart transplantation for Chagas cardiomyopathy and had developed a mass in the left ventricle with symptomatic ventricle outflow obstruction. The patient was initially treated with anti-coagulation but his condition worsened and he was given emergency surgery to remove the mass. The patient recovered well and histologic assessment revealed PTLD as the etiologic culprit. Lymphoproliferative disorders are the second most frequently identified malignant neoplasm after heart transplantation. B-cell tumors are the most common histologically and are associated with infection by Epstein-Barr virus in 80% to 90% of cases.
