“…Overall, 683 studies were selected. After an evaluation of records, 17 studies published between 2000 and 2020 were included in the review [ 1 , 5 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. In particular, nine were concerning patients with ventricular outpouchings (diverticula and congenital aneurysms), while eight were concerning patients with ventricular invaginations (crypts and recesses) ( Figure 1 ).…”

Cardiac ventricular outpouchings and invaginations are rare structural abnormalities and usually incidental findings during cardiac imaging. A definitive diagnosis is possible through the use of multimodality imaging. A systematic review of the literature was carried out in November 2022 to identify studies regarding ventricular outpouchings and invaginations. The main aim of the review is to summarize knowledge regarding epidemiology, etiology, diagnosis and prognosis of patients with ventricular outpouchings (aneurisms or diverticula) and invaginations (crypts and recesses). Overall, 26 studies published between 2000 and 2020 were included in the review. Diverticula and congenital aneurysms incidence ranges between 0.6 and 4.1%. Myocardial recesses and crypts range between 9% in the general population and up to 25% in patients with hypertrophic cardiomyopathy. The combined use of echocardiography, cardiac computed tomography (CCT) and cardiac magnetic resonance (CMR) is useful to establish tissue contractility, fibrosis, extension and relationship with adjacent structures for differential diagnosis of both invaginations and outpouchings. In conclusion, both outpouchings and invaginations are rare entities: a definitive diagnosis may be aided by the use of combining multiple imaging techniques, and the treatment depends both on the lesion-specific risk of complications and on the potential association of some lesions with cardiomyopathy.

“…They are most commonly solitary, located at the apex or under the mitral valve ring and are connected to the left ventricle, mainly by a narrow ostium and narrow neck [1,2,4]. LV diverticula size ranges from 0.5 cm to 1.4 cm [1,2,3], and its ostium is 0.2-1.2 cm [5]. The ratio of the ostium of the diverticulum connecting it to the left ventricle to the maximum diameter of the diverticulum is < 1 [3].…”

“…From a clinical point of view, cardiac diverticula are usually asymptomatic and are accidentally detected during imaging due to another occasion [1,2,3]. Some of the potential concomitant symptoms and conditions that may guide the diagnosis are atypical chest pain, ventricular arrhythmia, including sudden cardiac death, heart failure, mitral regurgitation, systemic embolism or wall rupture [1,3,5]. Due to the small number of patients with cardiac divertic-Фиг.…”

Myocardial diverticula are rare and incidental ﬁ ndings. They are most probably congenital anomalies of the cardiac wall, mainly of the left ventricle (LV), which in the majority of the cases are associated with other anomalies – cardiac, vascular or thoraco-abdominal. The lack of speciﬁ c clinical symptoms and electrocardiographic changes in the presence of cardiac diverticulum, make them most commonly an incidental ﬁ nding during a diagnostic imaging examination. The diagnosis of LV diverticulum can be made with echocardiography, left ventriculography, computed tomography or magnetic-resonance imaging (MRI). Among all, MRI gives the best morphologic assessment of the ventricular wall, the location and the relation of the diverticulum to surrounding structures and its dynamic behaviour during systole and diastole. MRI can rule out inﬂ ammatory, traumatic and ischemic cardiac pathology, and cardiomyopathy, and thus differentiate the diverticulum from another entity – myocardial crypts, pathologically formed focal aneurysm or pseudoaneurysm of the LV. Therefore, MRI is the preferred non-invasive method for evaluating the cardiac wall in detail and helps to differentiate and deﬁ nitively diagnose congenital cardiac diverticulum, which in most cases does not require therapeutic intervention.
