RESUMO
OBJECTIVES: To analyze how left ventricular (LV) remodeling and hypertrophy geometry evolve after surgical aortic valve replacement (SAVR) in octogenarian patients, and identify potential sex-related differences and implications for long-term outcomes. METHODS: In 170 patients with aortic stenosis ([AS], age 80 ± 4 years, 59% women), hypertrophy geometry and remodeling (LV index) were reanalyzed one year post-SAVR. The six-year outcomes were evaluated. RESULTS: Pre-SAVR, 65% of the women and 38.6% of the men (P < .001) showed adaptive remodeling. Concentric hypertrophy was prevalent in adaptive remodeling, and mixed and dilated hypertrophy were more prevalent in maladaptive remodeling. At one year, the remodeling patterns and sex distribution were similar to those observed pre-SAVR, but the LV index decreased in women and increased in men (P < .0001). Women with adaptive remodeling had a higher incidence of persistent concentric hypertrophy with higher LV filling pressures. Long-term survival was better in women and worse in men with adaptive remodeling (P = .039). Men with adaptive remodeling and men with concentric hypertrophy had the highest risk of cardiac death. This risk was similar between sexes for patients with maladaptive remodeling and dilated hypertrophy. Women with LV ejection fraction >55% had a lower risk of cardiac death than men. CONCLUSIONS: The long-term outcomes of SAVR differ between sexes in older patients with AS and adaptive LV remodeling. The LV index facilitates studying the pathways of adaptation to AS. The follow-up shifts help explain the sex differences in long-term outcomes post-SAVR. Concentric hypertrophy is associated with the highest risk of cardiac death in men.

Chordoma is a rare tumor, usually diagnosed when the disease is advanced. Despite its slow growth, it is locally aggressive and has a poor long-term prognosis. Surgery is the mainstay treatment. Although cardiac metastases are very rare, the heart is frequently involved in systemic neoplastic diseases. This report describes a typical case of metastatic chordoma: the age at first diagnosis, the site of the primary tumor, and the slow growth of the cardiac metastasis were all typical features. Surgical excision of the mass from the right ventricular outflow tract is described together with echocardiographic, radiologic, and histopathologic characteristics of the metastatic chordoma.

Papillary fibroelastoma (PF) of the right atrium accounts for 2% of nonvalvular cases, and right appendage (RAA) PF was described only once in literature. We present three cases of RAA PF in patients with unrelated symptoms undergoing 3-dimensional transesophageal echocardiographic examination (3D-TEE) scheduled for conventional indications. Key to diagnosis in routine practice resides in systematic examination of the right atrium and RAA in live 3D-TEE imaging with backward and forward navigation of the real-time pyramidal data. A review of literature is provided. Our experience demonstrates that systematic imaging of all cardiac structures with 3D-TEE allows refining PF nosology.

Direct oral anticoagulants (DOACs) have shown similar efficacy and safety with respect to warfarin in patients with atrial fibrillation (AF). However, the proportion of patients aged ≥85 years enrolled in clinical trials was low and the applicability of their results to very elderly patients is still uncertain. We have carried out a prospective cohort study on AF patients aged ≥85 years enrolled in the Survey on anticoagulaTed pAtients RegisTer (START2-Register) and treated with either VKAs or DOACs, with the aim to evaluate mortality, bleeding and thrombotic rates during a long-term follow-up. We enrolled 1124 patients who started anticoagulation at ≥85 years with VKA (58.7%) or DOACs (41.3%), Clinical characteristics of patients were similar, except for a higher prevalence of coronary artery disease and renal failure in VKAs patients and of a history of previous bleeding and previous stroke/TIA in patients on DOACs. Median CHA2DS2VASc and HAS-BLED scores were similar between the two groups. During follow-up, 47 major bleedings (rate 2.3 x100 pt-yrs) and 19 stroke/TIA (0.9 x100 pt-yrs) were recorded. The incidence of bleeding was similar between patients on VKAs and DOACs. Patients on DOACs showed a higher rate of thrombotic events during treatment (rate 1.84 and 0.50,respectively). Mortality rate was higher in patients on VKAs than in patients on DOACs (HR 0.64 (95% CI 0.46-0.91). In conclusion, we confirm the overall safety and effectiveness of anticoagulant treatment in very elderly AF patients, with lower mortality rates in DOACs patients, similar bleeding risk, and a higher risk for cerebral thrombotic events in DOACs patients.
