Behavior of echocardiographic parameters of right ventricular function after tricuspid surgery.

Evaluation of right ventricular (RV) function after tricuspid valve surgery is complex. The objective was to identify the most appropriate RV function parameters for this purpose. This prospective study included 70 patients undergoing cardiac and tricuspid valve (TV) surgery. RV size and function parameters were determined at 3 months and 1-year post-surgery. Categorical variables were analyzed with the McNemar test and numerical variables with the Student's t-test for related samples or, when non-normally distributed, the Wilcoxon test. Spearman's rho was used to determine correlations between variables at 3 months and 1 year. RV diameters were reduced at 3 months post-surgery and were then unchanged at 1 year. Tricuspid annular plane systolic excursion (TAPSE) and S' wave values were worse at 3 months and then improved at 1 year (t-score-2.35, p 0.023; t-score-2.68; p 0.010). There was no significant reduction in free wall longitudinal strain (LS) or shortening fraction (SF) at 3 months (t-score 1.421 and - 1.251; p 0.218 and 0.172), and they were only slightly below pre-surgical values at 1 year. No relationship was found between RV function parameters and mortality or major complications. During the first few months after TV surgery, LS may be a more appropriate parameter to evaluate global ventricular function in comparison to TAPSE. At 1 year, good correlations are observed between TAPSE, S' wave, and LS values.

Infective endocarditis on interventricular communication as cause of massive haemoptysis: a case report.

Background: Haemoptysis is a rare symptom associated with endocarditis. We describe the unusual clinical manifestation of endocarditis on regurgitant bicuspid aortic valve and (probably) secondarily on a perimembranous ventricular septal defect (VSD) as massive haemoptysis. Case summary: A 24-year-old male with aortic coarctation, bicuspid aortic valve, and VSD since birth. Previously asymptomatic, he came after an episode of haemoptysis. A computed tomography (CT) scan showed a cavitated lesion in lung. Streptococo viridans was identified in serial blood cultures. Transthoracic echocardiography showed a bicuspid aortic valve with vegetations, suggesting infectious involvement, and severe aortic insufficiency. Transoesophageal echocardiography (TEE) study showed a bicuspid aortic valve with complete fusion of coronary valves. An elongated oscillating tumour, 9.5 mm in length, was observed in the centre of the ventricular side of the non-coronary valve. Another vegetation was seen on the VSD. During his hospital stay and under antibiotic treatment, he reported abdominal pain. Computed tomography examination showed splenic infarction. In the echocardiogram no vegetation masses were observed on the aortic valve or on the VSD closure aneurysm. Discussion: The main debate about this patient's treatment concerned the indication of surgery, especially after the onset of fever with splenic septic embolism while under appropriate antibiotic treatment. He was stable, with no signs of heart failure and the echocardiogram repeated after the septic splenic embolism showed no residual vegetations on the aortic valve or VSD, and the TEE study ruled out a local complication. Finally, the multidisciplinary team decided against surgical management.
