RESUMO
OBJECTIVES: In patients at risk of developing right ventricular failure after cardiac surgery, right ventricular support with a ventricular assist device may be a promising strategy to reduce mortality. We present our experience with intraoperative right ventricular assist device implantation as a prevention strategy of right ventricular failure after cardiac surgery. METHODS: Between 2016 and 2022, we implanted four right ventricular assist devices prophylactically in a series of patients with surgical indication for valvular heart disease and high risk of postoperative right ventricular failure. Indications for the right ventricular assist device were suprasystemic pulmonary hypertension or severe right ventricular dysfunction. RESULTS: Externalization of the device cannulas through intercostal spaces was performed in three patients, allowing early mobilization and withdrawal without resternotomy. Removal of the device ocurred on the eighth postoperative day. ICU and hospital length of stay was 12 (±1.6) and 23 days (±4.2) respectively. Hospital mortality was null. No patient died during follow-up, mean follow-up was 32.5 months [1-72]. Patients improved their NYHA functional class up to grade II during follow-up. CONCLUSIONS: Acute right ventricular failure after cardiac surgery remains a significant cause of morbidity and mortality. Prophylactic strategies to prevent postoperative right ventricular dysfunction may decrease the incidence of refractory postoperative right ventricular failure. We propose a novel approach to prevent right failure after cardiac surgery with prophylactic intraoperative ventricular assist device implantation.

La trombosis venosa profunda puede causar embolias pulmonares. En raras ocasiones, la embolización se produce, no directamente en el árbol arterial pulmonar, sino en las cavidades cardiacas derechas. Aunque el valor de la ecocardiografía en el diagnóstico es bien reconocido, actualmente no existe consenso en cuanto al tratamiento apropiado. Presentamos seis casos de trombo flotante en aurícula derecha, diagnosticado por ecocardiografía, en pacientes con embolias pulmonares o con shock o síncope sin causa evidente. Se realizó embolectomía quirúrgica en 4 pacientes, y tratamiento fibrinolítico en 2, sin mortalidad hospitalaria. La elevada mortalidad asociada con esta patología puede reducirse con un diagnóstico ecocardiográfico rápido y un tratamiento emergente con fibrinolisis o cirugía. Nuestros datos sugieren la posible utilización de la fibrinolisis como tratamiento de primera elección en casos seleccionados
