Previous studies that attempted to identify baseline clinical, laboratory and echocardiographic predictors of embolization led to conflicting results. Objectives: To assess the value of clinical, laboratory and echocardiographic variables in predicting embolic events and in-hospital mortality in patients with definite left-sided IE. Methods: This prospective study involved 99 patients with definite left-sided IE recruited from the prospective IE database of Cairo University Hospitals. TTE was performed in all patients. TEE was performed in 62.6% of the patients. Results: Embolization occured in 40.4% of patients during index hospitalization. Female gender was a highly significant risk factor for embolization (p = 0.003). The only echocardiographic variable useful in predicting embolization was vegetation length (p = 0.04). At a cutoff value of 2.095 cm, the sensivity for predicting embolization was 50%, specificity 69.1% and positive predictive value 52.8%. Vegetation length was predictive of embolization in females (p = 0.003), but not in males and in native valves (p = 0.05), but not in prosthetic valves. The overall in-hospital mortality rate was 41.8%. Atrial fibrillation/flutter was a powerful predictor of mortality (p = 0.001) as compared to sinus rhythm. Not having surgery was a powerful predictor of mortality (p < 0.001), even if prosthetic valve IE was excluded from the analysis. Additionally, the presence of heart failure functional class III/IV or fulminant sepsis necessitating inotropic support were significant predictors of mortality (p = 0.007 & <0.001 respectively). The only echocardiographic parameter useful in predicting mortality was the presence of valvular stenosis (p = 0.05). Conclusions: This study clearly shows that female gender is a highly significant risk factor for embolization, and that vegetation length is a useful predictor of embolization in females and in native valve IE. Atrial fibrillation/flutter, not having surgery, advanced heart failure and fulminant sepsis are all useful predictors of mortality, which allows identification of high-risk paients in whom an aggressive strategy will be potentially useful.

Naqueles com insuficiência cardíaca (IC) demonstrou-se que esse défice se associa a pior prognóstico. Existem poucos dados na literatura relativamente ao impacto prognóstico do DeF nas síndromes coronárias agudas (SCA), sendo este o principal objetivo deste estudo. Métodos: Estudo observacional retrospetivo que incluiu 817 doentes admitidos por SCA. Definiram-se dois grupos de acordo com a presença (n = 298) ou ausência de DeF (n = 519) à admissão. O evento clínico estudado foi a ocorrência de morte ou IC grave em longo prazo. Calcularam-se os preditores independentes de prognóstico com base na análise de regressão logística. Resultados: Verificou-se que 36% dos doentes tinham DeF. Estes doentes apresentaram maior taxa de mortalidade (p = 0,004) e de IC (p = 0,011) durante o follow-up, bem como maior taxa de readmissões hospitalares (p = 0,048).

It has an aggressive nature, with highly variable clinical features, which results in delayed diagnosis and high mortality. We report a 19-year-old man presented to the ED with a three-month history of hemoptysis and one-week history of anterior chest pain. Additionally, an aortic diastolic murmur grade II/VI was found on physical examination. Thoracic CT scan revealed bilateral dispersed hypodense pulmonary nodes with peripheral halo, alveolar densification, and pericardial effusion. The transthoracic echocardiogram confirmed sizeable pericardial effusion and bicuspid aortic valve, without other significant findings. A pericardiocentesis removed 1300 mL of hemorrhagic fluid, consistent with an exudate without malignant cells. Both cardiac magnetic resonance and transesophageal echocardiogram revealed a large mass on the right atrium's anterior wall. Mass biopsy was performed, revealing malignant cardiac angiosarcoma. The biopsy of the lung lesions was compatible with lung metastasis of primary cardiac angiosarcoma. The patient was submitted to palliative chemotherapy but died 12 months after the diagnosis.

Primary coronary angioplasty and stenting of this artery were performed. Twelve hours later the patient became hemodynamically unstable and severe mitral regurgitation due to rupture of one of the heads of the anterolateral papillary muscle was diagnosed. Emergency surgery was performed (papillary muscle head reimplantation, mitral annuloplasty with a rigid ring, tricuspid annuloplasty and coronary artery bypass grafting). On surgical inspection, it was observed that the detached muscle head had become trapped in the left ventricle by a secondary cord attached to the other head. This case is unusual in presenting two uncommon features of ischemic papillary muscle: rupture of the anterolateral muscle in myocardial infarction involving the inferoposterior wall...

Ecocardiograma transesofágico (ETE) com vegetação apensa ao folheto posterior da válvula mitral, colocando-se a hipótese de endocardite infeciosa, tendo-se iniciado antibioterapia empírica. Repetição de ecocardiograma transesofágico após antibioterapia com manutenção da vegetação referida e menção a outra de menores dimensões, sendo colocada a hipótese de endocardite trombótica não bacteriana. A investigação clínica não evidenciou qualquer processo infecioso. Após hipocoagulação durante dois meses, foi repetido o ecocardiograma transesofágico com desaparecimento das vegetações anteriormente apresentadas.

Aims To evaluate paravalvular aortic regurgitations after 30-day after TAVI using the Edwards SAPIEN 3 prosthesis. Methods Prospective monocentric study including 66 high-risk or nonoperable patients with severe aortic stenosis undergoing TAVI using Edwards SAPIEN 3 prosthesis via transfemoral access, between September 2014 and March 2015. Results Mean age of patient was 84±7,1 years (70% female). The MDCT estimated an aortic annular diameter 25,07±2mm. Mean logistic EuroSCORE was 15,8±10,8. In our study, the device success rate was 98.5%. The prosthesis has been deployed correctly in all cases and no failure of valve or embolization had occurred. Post TAVR, mean transaortic gradient decreased from 46,0±12,33mmHg to 8,2±3,37mmHg (p<0.001). No patient had moderate or severe PAR. At 30 days follow up, transthoracic echocardiography (TTE) showed that the PAR was absent or trivial in 66% of patients and mild in the remainder. Possible reasons for this low PAR rate include: 1) the outer polyethylene terephthalate sealing cuff, which enhances paravalvular sealing; 2) more accurate positioning; and 3) improved sizing with adjunctive MDCT. Conclusion In our study, TAVI with Edwards SAPIEN 3 demonstrated lower paravalvular aortic leak rates than earlier generation devices in patients at high risk for surgery.

Six weeks prior to admission, the patient had undergone cardiac surgery. The ECG showed diffuse ST segment elevation and PR segment depression. The blood tests revealed increased inflammatory markers and negative myocardial necrosis markers. Pericardial and left-sided pleural effusion were noted. Sterile blood cultures were negative. Hence, the hypothesis of Dressler’s syndrome was established. The patient improved clinically and analytically with a short course of anti-inflammatory therapy and was discharged with colchicine and acetylsalicylic acid. A thoracic radiography performed 2 months after showed complete remission of pleural effusion.
