Project description:Isolated pulmonary valve endocarditis (IPE) is a rare form of infectious endocarditis. This article reports the case of a 49-year-old patient with IPE who was initially admitted with suspected cholecystitis. After vegetations were detected by transthoracic (TTE) and transesophageal echocardiography (TEE), antibiotic therapy in accordance with the antibiogram was primarily attempted; however, due to persistently elevated infection parameters and structural valve damage a pulmonary valve replacement was eventually performed.
Project description:Double-chambered right ventricle (DCRV) is a rare congenital heart disorder involving 2 different right ventricle (RV) pressure compartments that is often associated with ventricular septal defect (VSD). Usually, the obstruction is caused by an anomalous muscle bundle crossing the RV from the interventricular septum to the RV free wall. We are reporting a case of double-chambered right ventricle associated with ventricular septal defect and congenital absence of the pulmonary valve, a rare form of congenital infundibular pulmonary stenosis. In addition to ventricular septal defect, our patient had congenital absence of the pulmonary valve, which is very unusual and has never been reported to our knowledge.
Project description:ObjectivesWe aimed to assess the procedural and clinical results of transcatheter aortic valve replacement (TAVR) for nonraphe bicuspid aortic stenosis (AS) with coronary vs mixed cusp fusion.BackgroundIt remains unclear whether cusp fusion morphology affects TAVR outcomes in patients with nonraphe bicuspid AS.MethodsThis retrospective study enrolled consecutive patients with severe symptomatic AS and type-0 bicuspid aortic valve, who underwent TAVR at our institution between 2012 and 2017. TAVR outcomes were defined based on the Valve Academic Research Consortium-2 recommendations.ResultsCompared to patients with mixed cusp fusion (44/71), those with coronary cusp fusion (27/71) had a larger ellipticity index for the aortic annulus (21.9% ± 9.0% vs 15.6% ± 9.3%, p=0.007) and increased left ventricular outflow tract obstruction (31.1% ± 9.4% vs 26.9% ± 7.5%, p=0.04) but comparable rates of second valve implantation (15.9% vs 14.8%), mild paravalvular leakage (PVL, 38.5% vs 30.2%), permanent pacemaker implantation (PPM, 25.9% vs 15.9%), and 30-day mortality (7.4% vs 6.8%). Use of a first-generation transcatheter heart valve was associated with higher risk for mild PVL (odds ratio (OR) = 4.37; 95% confidence interval (95% CI) = 1.14-16.75; p=0.03) but not PPM (OR = 0.77; 95% CI = 0.22-2.62; p=0.67), whereas a larger oversizing ratio tended to be associated with a higher PPM rate (OR = 1.49; 95% CI = 0.46-4.86; p=0.51) but lower incidence of mild PVL (OR = 0.51; 95% CI = 0.19-1.35; p=0.17).ConclusionsIn AS patients with type-0 bicuspid valves, cusp fusion morphology does not affect the procedural or clinical results of TAVR. Use of second-generation transcatheter heart valves may provide more favorable results in such patients. This trial is registered with NCT01683474.
Project description:BackgroundIntercostal lung herniation is a rare condition that may be congenital (20%) or acquired (80%). The isolated congenital form is exceptional, with one case reported in the literature.Case presentationWe report a case of a 10-year-old French boy of Algeria origin, born with intermittent swelling of his right hemithorax. The swelling and pain gradually increased with age. A clinical examination revealed a localized swelling of his right hemithorax at the level of the midclavicular line and the fifth intercostal space. The swelling increased in size during respiratory movements and enlarged with Valsalva maneuvers. The intercostal lung hernia was treated by thoracoscopy.ConclusionsThis is the second case of isolated congenital intercostal pulmonary hernia reported in the French and English literature. It is the first to be treated by thoracoscopy. Based on this case we performed a review of the diagnosis and therapeutic aspect of pulmonary hernias.
Project description:IntroductionCongenital unilateral absence of pulmonary artery (UAPA) is a rare congenital anomaly with the complete absence of intrapericardial segment of one of the branch pulmonary arteries. Sixty percent are associated with other congenital heart defects (CHD) that often need correction.AimTo analyze the data of patients with UAPA and ipsilateral non-unifocalizable major aortopulmonary collateral arteries (MAPCAs) associated with other CHD to identify the commonly associated CHD, their management strategies and outcomes.Materials and methodsRetrospective data of patients admitted for congenital UAPA with other CHD was compiled from hospital records from 2002 to 2015. The associated CHD were categorized as group I with the decreased pulmonary flow and group II with increased pulmonary flow to the unaffected contralateral pulmonary artery. The determinants of their management were analyzed.ResultsSixty-five patients of UAPA and ipsilateral non-unifocalizable MAPCAs associated with other CHD were identified. Group I had 41 patients and Group II had 24. The most common CHD associated with UAPA was tetralogy of Fallot (TOF) in 31 patients (47.7%). Fifty-three patients underwent surgery, 48 (73.8%) underwent single lung corrective surgery, 5 (7.6%) palliative surgery and 12 (18.4) received no surgery. Four operated patients died in the immediate postoperative period. The lowest Mc Goon ratio and Nakata index to undergo corrective surgery were 1.0 and 87.4 mm2/m2. A follow-up of 21 patients was done, among which 11 patients who underwent single-stage corrective surgery, all are in NYHA class II and saturating above 95%.ConclusionsCongenital UAPA is a rare anomaly and associated with a variety of CHDs, TOF being the most common. Single lung corrective surgery in patients with ipsilateral non-unifocalizable MAPCAs has good immediate and long term survival.
