A rare case of papillary fibroelastoma involving the tricuspid valve. A single center experience over a period of 22 years (1999-2021).

BACKGROUND AND AIM: Papillary fibroelastoma (PFE) represents only 16% of the benign cardiac tumor and approximately 15% of these are located on the tricuspid valve. MATERIALS AND METHODS: Over a period of 22 years (1999-2021) we observed 75 pts with cardiac tumors at our Center over 9650 pts operated on but only one case of a tricuspid valve PFE in a 69-year-old patient. Trans-thoracic echocardiography demonstrated a mobile mass (20 × 10 mm), adhering to the atrial side of the septal leaflet of the tricuspid valve of unknown origin. In consideration of the mobility of the mass and the consequent high embolic risk, surgical removal was made. The patient underwent surgery through a median sternotomy on CPBP. A 'gelatinous' mass adhering to the tricuspid leaflet was found and completely removed. The postoperative course was uneventful. The pathological diagnosis was PFE. CONCLUSIONS: PFEs of the tricuspid valve are rare entities being in most cases found incidentally. In our experience, the incidence of this tumor in this location is 1/10,000 cases of cardiac surgery. Although most patients are asymptomatic, surgical treatment is nevertheless recommended in consideration of the high embolic risk.

Temporal Trends, Characteristics, and Outcomes of Infective Endocarditis After Transcatheter Aortic Valve Replacement.

BACKGROUND: Procedural improvements combined with the contemporary clinical profile of patients undergoing transcatheter aortic valve replacement (TAVR) may have influenced the incidence and outcomes of infective endocarditis (IE) following TAVR. We aimed to determine the temporal trends, characteristics, and outcomes of IE post-TAVR. METHODS: Observational study including 552 patients presenting definite IE post-TAVR. Patients were divided in 2 groups according to the timing of TAVR (historical cohort [HC]: before 2014; contemporary cohort [CC]: after 2014). RESULTS: Overall incidence rates of IE were similar in both cohorts (CC vs HC: 5.45 vs 6.52 per 1000 person-years; P = .12), but the rate of early IE was lower in the CC (2.29‰ vs 4.89‰, P < .001). Enterococci were the most frequent microorganism. Most patients presented complicated IE ( CC: 67.7%; HC: 69.6%; P = .66), but the rate of surgical treatment remained low (CC: 20.7%; HC: 17.3%; P = .32). The CC exhibited lower rates of in-hospital acute kidney injury (35.1% vs 44.6%; P = .036) and in-hospital (26.6% vs 36.4%; P = .016) and 1-year (37.8% vs 53.5%; P < .001) mortality. Higher logistic EuroScore, Staphylococcus aureus etiology, and complications (stroke, heart failure, and acute renal failure) were associated with in-hospital mortality in multivariable analyses (P < .05 for all). CONCLUSIONS: Although overall IE incidence has remained stable, the incidence of early IE has declined in recent years. The microorganism, high rate of complications, and very low rate of surgical treatment remained similar. In-hospital and 1-year mortality rates were high but progressively decreased over time.

Infective Endocarditis Following Transcatheter Aortic Valve Replacement: Comparison of Balloon- Versus Self-Expandable Valves.

BACKGROUND: No data exist about the characteristics of infective endocarditis (IE) post-transcatheter aortic valve replacement (TAVR) according to transcatheter valve type. We aimed to determine the incidence, clinical characteristics, and outcomes of patients with IE post-TAVR treated with balloon-expandable valve (BEV) versus self-expanding valve (SEV) systems. METHODS: Data from the multicenter Infectious Endocarditis After TAVR International Registry was used to compare IE patients with BEV versus SEV. RESULTS: A total of 245 patients with IE post-TAVR were included (SEV, 47%; BEV, 53%). The timing between TAVR and IE was similar between groups (SEV, 5.5 [1.2-15] months versus BEV, 5.3 [1.7-11.4] months; P=0.89). Enterococcal IE was more frequent in the SEV group (36.5% versus 15.4%; P<0.01), and vegetation location differed according to valve type (stent frame, SEV, 18.6%; BEV, 6.9%; P=0.01; valve leaflet, SEV, 23.9%; BEV, 38.5%; P=0.01). BEV recipients had a higher rate of stroke/systemic embolism (20.0% versus 8.7%, adjusted OR: 2.46, 95% CI: 1.04-5.82, P=0.04). Surgical explant of the transcatheter valve (SEV, 8.7%; BEV, 13.8%; P=0.21), and in-hospital death at the time of IE episode (SEV, 35.6%; BEV, 37.7%; P=0.74) were similar between groups. After a mean follow-up of 13±12 months, 59.1% and 54.6% of the SEV and BEV recipients, respectively, had died (P=0.66). CONCLUSIONS: The characteristics of IE post-TAVR, including microorganism type, vegetation location, and embolic complications but not early or late mortality, differed according to valve type. These results may help to guide the diagnosis and management of IE and inform future research studies in the field.

Nuss procedure in adult pectus excavatum: a simple artifice to reduce sternal tension.

Nowadays the Nuss operation represents the standard surgical choice for pectus excavatum repair in children and teenagers. Some concerns have been raised regarding its applicability in adults, as compared with younger patients, in view of the higher rate of complications after surgery. We describe an easy trick that has been performed on a 36-year old man with a moderate pectus excavatum after an unsatisfactory Nuss procedure. It consisted of a T-shaped partial anterior sternotomy, performed after positioning of the stainless steel bar, in order to promote a hinge mechanism of the sternum to reduce the tension over the reinforcement. This procedure was successful with well-controlled postoperative pain and great patient satisfaction. No complications were recorded at 1-year follow-up. In our opinion, this simple trick could represent a valid surgical option for pectus excavatum repair in late adolescents and adults to obviate the occurrence of major sternal tension.

The 37-year durability of a Björk-Shiley Delrin-disc aortic valve prosthesis.

We report the exceptional longevity of a Björk-Shiley Delrin-disc prosthetic aortic valve that had been implanted in a man who underwent surgical correction of an ascending aortic aneurysm 37 years later. Upon explantation of the valve, the Delrin disc had only shallow abrasion on the ventricular surface, and none on the aortic surface. We discuss the soundness and durability of this valve in our patient, in contrast with its short functional prosthetic life in other patients. The 37-year lifespan of this patient's Björk-Shiley Delrin-disc valve is among the longest reported.

The role of psychological support in cardiac surgery: initial experience.

The scientific literature has pointed out several predictors of negative outcome after surgery such as pain and depression, negatively affecting the postoperative outcome in cardiac surgery. From January 2009 until June 2010, 15 patients scheduled for cardiac surgery were enrolled. The patients were assessed by psychological evaluation either in the hospital stay either in the rehabilitation period with the aim of identifying their emotional condition (sentiments about the onset of the disease, support received from family and friends) even by means of preformed tests for anxiety and depression (tests of Stay and Back). Thus, in our preliminary experience, the psychological evaluation failed to detect the occurrence of postoperative complications. Conversely, the psychological evaluation is very effective in detecting a poor emotional state and the psychological support decreases the degree of anxiety and depression with positive effects on postoperative outcome. In conclusion, a standardize test for anxiety and depression should be used for patients at hospital admission to detect who may benefits by psychological support.
