Abstract Background Right ventricular diverticula (RVD) are very rare congenital anomalies and their association with constrictive pericarditis is even rarer. So far, only one case has been published in literature. Case summary We report a case of multiple congenital RVD with constrictive pericarditis and right heart failure which was incidentally identified on surveillance computed tomography (CT) for abdominal lymphangioma. Interval CT, echocardiography, and cardiac magnetic resonance imaging (CMR) studies were performed and reviewed. Computed tomography abdomen showed hepatic congestion with features of portal hypertension, increasing size of the RVD on review of serial CTs, and eccentric foci of pericardial calcification. Echocardiography performed for breathlessness demonstrated supranormal early diastolic tissue velocities with average of 19.8 cms−1 and a septal bounce phenomenon on m-mode imaging suggesting constrictive physiology, which triggered a CMR referral. Cardiac magnetic resonance imaging HASTE and right ventricular (RV) outflow tract imaging showed four outpouchings along RV free wall, the largest measuring 4.5 × 2 cm with a sizeable neck. These outpouchings displayed a trabecular network and/or were contractile aiding the diagnosis of diverticula as opposed to aneurysms. Right ventricular function was moderately compromised, whereas left ventricular function was preserved. Discussion Right ventricular diverticula can be associated with, and potentially be causative of, pericardial thickening and calcification eventually leading to constrictive pericarditis and heart failure.

Pulmonary hypertension is defined by a mean pulmonary artery pressure ≥25 mmHg at rest, measured during right heart catheterization. Ventricular noncompaction is a genetic cardiomyopathy which mostly effects left ventricle. It is related with deterioration of myocardial embryogenesis and commonly together with other cardiac diseases (1). Isolated ventricular non-compaction is characterized by modified morphology of myocardial wall, increased trabeculation in ventricular cavity and deep intertrabecular recesses. A 43-year-old woman presented exercise induced dyspnea and atypical chest pain. She has not any medical history prior. On admission, her 12 lead ECG showed complete righ bundle branch block, her blood pressure was 120/80 and pulse rate 80 per minutes. Transthoracic 2D echocardiogram and magnetic resonance imaging showed dilated and hypertrophied right ventricle with non-compaction of the right ventricular apex. The systolic pulmonary arterial pressure was 80 mmHg on the Doppler echocardiography. The coronary angiography revealed normal coronary arteries. The catheterization was showed pulmonary hypertension, right ventricle non-compaction and negative pulmonary vasoreactivity testing. Ventricular noncompaction, especially right ventricular noncompaction, complicated by severe pulmonary hypertension is exceptional. Only a few isolated right ventricular noncompaction has been reported but inclusion of pulmonary hypertesion cases are rare subsets . Diagnosis of pulmonary hypertension may be a consequence of increased pulmonary venous pressures caused by systolic and diastolic ventricular dysfunction secondary to right ventricular noncompaction. Widespread usage of cardiac magnetic resonance imaging, may enhance visual quality and evaluation of ventricular morphology, probably this will provide prevalance increment and clinical outcome improvements. Early diagnosis would bring better results.

Objective: The purpose of the study is to compare phase contrast (PC) imaging with invasive measurements of cardiac output (CO) in patients with pulmonary hypertension (PH). Materials and Methods: We analyzed 81 cases with PH who underwent cardiac magnetic resonance imaging and right heart catheterization (RHC). Measurement of CO and stroke volume (SV) by cardiac magnetic resonance (CMR) was performed by PC imaging of the proximal aorta (Ao) and pulmonary artery (Pa) and by RHC using the Fick and thermodilution (TD) methods. Results: There was good correlation in CO measurements between PC and RHC; however, there was better correlation with SV measurements; Fick-TD (r=0.85), PC-TD (Ao r=0.77, Pa r=0.79), and PC-Fick (Ao r = 0.73, Pa r = 0.78). Bland-Altman analysis of SV showed that Pa PC had slightly lower standard deviation than Ao PC; PC-Fick (Pa SD = 15.11 vs. Ao SD = 16.4 ml) and PC-TD (Pa SD = 16.99 ml vs. Ao SD = 17.4 ml) while Fick-TD had the lowest (SD = 14.4 ml). Compared to Fick, measurement of SV with Ao PC (‒4.12 ml) and Pa PC (0.22 ml) both had lower mean difference than TD (‒11.1 ml). Conclusion: Non-invasive measurement of CO and SV using PC-CMR correlates well with invasive measurement using RHC. Our study showed that PC-CMR had high accuracy and precision when compared to Fick. Among all the modalities, PC-CMR contributed the least amount of variation in measurements.
