ABSTRACT

BACKGROUND: Currently, studies are underway to determine whether coronary stent implantation with percutaneous transluminal coronary angioplasty before a coronary artery bypass graft (CABG) influences the prognosis of surgery. This study aimed to assess the need for future revascularisation or all-cause mortality as a composite endpoint after CABG surgery among patients with previous stent implantation. METHODS: A retrospective, non-randomised study was performed on 721 patients who underwent CABGin our centre between 2012 and 2017. This single-centre study compared two groups: 1) the previous stent group, patients with previous stent implantation (n=144), and 2) the non-previous stent group, patients without previous stent implantation (n=577). RESULTS: After a median follow-up of 36 months, the previous stent group presented a decreased combined event-free survival at 1, 3 and 5 years compared with the non-previous stent group (67.4, 43.5 and 23.0% vs. 91.0, 80.3 and 63.0%, respectively; p<0.01). There was also higher mortality in the previous stent group than in the non-previous stent group (96.1, 90.5 and 79.4 vs. 91.9, 75.9 and 51.0, respectively; p=0.01). The multivariable analysis of demographics, baseline comorbidity and surgical data showed previous stent implantation as an independent predictor of the composite endpoint (Hazard Ratio=3.00 and 95% confident interval=2.09-4.32; p<0.01). CONCLUSION: Patients with percutaneous coronary intervention before CABG present higher comorbidities and clinical events during follow-up than those who do not undergo stenting.

ABSTRACT

BACKGROUND: Autonomic imbalance characterized by sympathetic predominance and decreased parasympathetic transmission is a classic feature of heart failure (HF) with reduced left ventricular ejection fraction, leading to disease progression, exercise intolerance, ventricular remodelling, arrhythmias, and premature death. The underlying mechanisms to these processes are not yet fully understood, but the current treatments influence this dysregulation, towards an inhibition of sympathetic hyperactivation. New therapies, such as the stimulation of carotid baroreceptors, enhance this inhibition to restore autonomic balance and to be able to cope with these mechanisms. CASE SUMMARY: We report the case of a 76-year-old male with advanced HF at an advanced stage, refractory to optimal treatment, and included in a programme of ambulatory infusions of Levosimendan as compassionate treatment. The patient presented with multiple episodes of decompensated HF secondary to ventricular arrhythmias. A multidisciplinary team decided to implant a baroreceptor stimulator device (Barostim Neo) in order to improve HF symptoms and quality of life, as well as trying to decrease the burden of arrhythmias. The procedure was performed with no complications and good therapeutic response, resulting in a significant reduction of arrhythmias. DISCUSSION: Treatment with a baroreceptor stimulating device is presented as a safe and effective option in our patients with advanced HF refractory to conventional treatment, to improve their quality of life and reduce symptoms; in addition to appearing as a promising option in those with arrhythmic events, which are difficult to control with usual treatments and procedures.

ABSTRACT

BACKGROUND: Isolated tricuspid valve surgery is a rarely performed procedure and traditionally is associated with a bad prognosis, although its clinical outcomes still are little known. The aim of this study was to assess the short- and long-term clinical outcomes obtained at our center after isolated tricuspid valve surgery as treatment for severe tricuspid regurgitation. METHODS: This retrospective study included 71 consecutive patients with severe tricuspid regurgitation who underwent isolated tricuspid valve surgery between December 1996 and December 2017. Perioperative and long-term mortality, tricuspid valve reoperation, and functional class were analyzed after follow up. RESULTS: Regarding surgery, 7% of patients received a De Vega annuloplasty, 14.1% an annuloplasty ring, 11.3% a mechanical prosthesis, and 67.6% a biological prosthesis. Perioperative mortality was 12.7% and no variable was shown to be predictive of this event. After a median follow up of 45.5 months, long-term mortality was 36.6%, and the multivariate analysis identified atrial fibrillation as the only predictor (Hazard Ratio 3.014, 95% confidence interval 1.06-8.566; P = 0.038). At the end of follow up, 63.6% of survivors had functional class I. CONCLUSIONS: Isolated tricuspid valve surgery was infrequent in our center. Perioperative mortality was high, as was long-term mortality. However, a high percentage of survivors were barely symptomatic after follow up.

ABSTRACT

Angiosarcoma (AS) is a type of malignancy within sarcomas affecting soft tissue and bone. It presents a very heterogeneous distribution in the human body, and it can appear in multiple locations, from breast to liver or skin. The incidence of this type of tumor is low; however, it is aggressive and requires an early diagnosis to initiate the treatment as soon as possible. In the present article, we report the case of a male patient who was diagnosed with epithelioid AS of popliteal artery after an aneurysm popliteal surgery, as well as its treatment and evolution. This kind of tumors has controversial treatment and poor survival rates in the early years.
