Anomalous origin of right pulmonary artery: diagnosis, treatment, and follow-up in an adult patient.

Anomalous origin of a branch pulmonary artery from the aorta is a rare malformation, accounting for 0.12% of all congenital heart defects. We present the case of a 43-year-old man with an anomalous origin of the right pulmonary artery (AORPA) from the ascending aorta. Reimplantation of the right pulmonary artery was carried out successfully, with favourable evolution in the medium-term follow-up. It is the first described case that receives corrective treatment in adulthood with a favourable evolution.

Evaluation of the endothelial function in hypertensive patients with 13N-ammonia PET.

BACKGROUND: Essential hypertension is one of the main risk factors for the development of coronary artery disease (CAD). Hypertension causes endothelial dysfunction which is considered an early sign for the development of CAD. Positron emission tomography is a non-invasive imaging technique that measures myocardial blood flow (MBF), allowing us to identify patients with endothelial dysfunction. METHODS AND RESULTS: 19 patients without comorbidities recently diagnosed hypertensive, as well as 21 healthy volunteers were studied. A three-phase (rest, cold pressor test, and adenosine-induced hyperemia) (13)N-ammonia PET was performed, and MBF was measured. Endothelial-Dependent Vasodilation Index, ΔMBF, and coronary flow reserve (CFR) were calculated for each patient. Hypertensive patients had a significantly higher systolic and diastolic blood pressures compared with the control group (134.6 ± 11.7/86.4 ± 10.6 mm Hg and 106.0 ± 11.8/71.4 ± 6.6 mm Hg, respectively, P < .001). The ENDEVI (1.28 ± 0.26 vs 1.79 ± 0.30, P < .001), the ΔMBF (0.81 ± 0.50 vs 0.25 ± 0.21, P < .001) and the CFR (2.18 ± 0.88 vs 3.17 ± 0.68, P = .001) were significantly lower in the hypertensive patients compared to the control group, 84% of the former group had endothelial dysfunction i.e., ENDEVI < 1.5 and 58% had vasomotor abnormalities, i.e., CFR < 2.5. CONCLUSIONS: In this study, we showed that recently diagnosed hypertensive patients have coronary endothelial dysfunction and vasomotor disturbances which are early signs for the development of CAD.

An Unusual Equatorial Constriction of the Ventricular Cone.

A 25-year-old woman with a recent diagnosis of congenital heart disease and probable endocarditis was referred to our institution. During our evaluation we observed an unusual deformation of both ventricles. We discuss its possible origin as revealed by printing of a three-dimensional model. (Level of Difficulty: Advanced.).

Vieussens' ring fistula to pulmonary artery: embolization with grandmother-mother-child technique.

A 53-year-old man with an asymptomatic fistula from the Vieussens ring to the pulmonary artery presented with progressive respiratory distress. Coil embolization of this type of fistula has been described by femoral access. The advanced transradial "grandmother-mother-son" technique for high active support safely allows successful embolization of this type of coronary fistulae.

Un hombre de 53 años con una fístula asintomática del anillo de Vieussens a la arteria pulmonar comenzó con dificultad respiratoria progresiva. La embolización con coils de este tipo de fístulas ha sido descrita por acceso femoral. La técnica transradial avanzada "abuela-madre-hijo" para un alto soporte activo permite de manera segura la embolización exitosa de este tipo fístulas coronarias.

Applicability of the Leiden Convention and the Lipton Classification in Patients with a Single Coronary Artery in the Setting of Congenital Heart Disease.

In single coronary artery (SCA) anatomy, all coronary tributaries arise from a single ostium, providing perfusion to the entire myocardium. Coronary classification systems can facilitate the description of SCA anatomy. Aim: Evaluation of the applicability of Lipton classification and the Leiden Convention coronary coding system in SCA. Methods: All patients (n = 6209) who underwent computed tomography (CT) scanning between 2014 and 2018 were retrospectively examined for the presence of SCA and classified, according to Lipton classification and the Leiden Convention coronary coding system. Results: The prevalence of SCA was 0.51% (32/6209). Twenty-eight patients (87.5%) had coexisting congenital heart disease (CHD), most frequently pulmonary atresia (9/32, 28.1%). Ten patients (10/32, 31.25%) could not be classified with either the Leiden Convention or Lipton classification (pulmonary atresia n = 9, common arterial trunk (CAT) n = 1). In one case with CAT, Lipton classification, but not the Leiden Convention, could be applied. In two cases with the transposition of the great arteries and in two cases of double outlet right ventricle, the Leiden Convention, but not the Lipton classification, could be applied. Conclusions: Both classifications are useful to detail information about SCA. As Lipton classification was not developed for structural heart disease cases, in complex CHD with abnormal position of the great arteries, the Leiden Convention is better applicable. The use of both systems is limited in pulmonary atresia. In this scenario, it is better to provide a precise description of the coronary origin and associated characteristics that might affect treatment and prognosis.
