The objective of our study was to compare the results of HBPM to ABPM considered as the reference technique and to determine its contribution in the management of hypertension Design and method: An analytical cross-sectional study including 100 patients aged > 18 years, followed at the outpatient cardiology clinic of the Mohamed Taher Maamouri university hospital in Nabeul over a six months period (July-December 2021). Patients were asked to measure blood pressure (BP) at home as instructed by the physician using validated blood pressure self-measurement devices (MICROLIFE BP A3 PLUS, MICROLIFE BP A2 Basic and Beurer BM 40 ). Laying of ABPM was performed immediately after the HBPM using a Bravo Mini validated device from Sun Tech Medical. The correlation was analyzed using Pearson cor...

Ambulatory blood pressure monitoring (ABPM) provide a more comprehensive assessment of blood pressure over the course of a day. This study examined the correlation between clinic and ambulatory BP measurements. Design and method: We collated clinic and 24 hour ambulatory BP data of 100 patients aged > 18 years from the outpatient cardiology clinic of Mohamed Taher Maamouri University hospital in Nabeul (n = 100) over a six months period (July-December 2021). Laying of ABPM was performed using a Bravo Mini validated device from Sun Tech Medical. We used the Pearson correlation coefficient (r) to measure the strength of the relationship between these two measurements methods. Results: The mean age of our population was 59.14±13.12 years (range 21-92 years), composed of 47 women and 53 men. The most frequent reason for carrying out ABPM was the monitoring of hypertensive pa...

This study assessed the value of ECG-gated multidetector computed tomography (MDCT) as a complementary imaging modality in suspected prosthetic dysfunction. Method Patients with suspected mechanical PHV dysfunction were prospectively recruited between 2018 and 2020 in the cardiology department of Ariana hospital. All patients underwent transthoracic/transesophageal echocardiography and additional MDCT imaging. We compared the diagnosis based on echocardiography and on MDCT information. Results Our study enrolled 32 patients (median age was 53.7 years: 26–76). 16 patients had an aortic prosthetic valve (50%), 8 patients had a mitral prosthetic valve (25%), 8 patients had mitro-aortic prosthetic valves (25%). An obstructive dysfonction was noticed in 23 patients (72%): a thrombus in 12 cases, a pannus in 4 cases, a mismatch in 2 cases and a reduction in a leaflet motion in 4 cases, a vegetation in one case. A regurgitation was noticed in 4 patients: two paraprosthetic regurgitation and two paraprosthetic aneurysm. Ultrasound imaging and MDCT found same results for mismatach. Echocardiogram was more performant in the diagnosis of thrombosis (P = 0,02). The addition of MDCT showed incremental value in detecting pannus (P = 0,02), leaflet restriction and paraprosthetic aneurysm.The leaflet restriction diagnosed by CT in significantly associated with thrombus (P = 0,03) ( Fig. 1 ). Conclusion Mechanical PHV dysfunction is rare but life-threatening. A multimodality imaging assessment (ultrasound and CT) is necessary to precise mechanism and indicate the appropriate treatment. MDCT imaging is superior for detecting pannus and leaflet motion restriction.
