Background: Valvular heart disease constitutes a considerable amount of cardiovascular morbidity and mortality worldwide. There is a scarcity of data from Africa.
Methods: In this descriptive, cross-sectional study, we documented the demographic, clinical and echocardiographic features of current patients with adult mitral valve disease (MVD) at Chris Hani Baragwanath Academic Hospital from December 2018 to March 2019.
Results: The study included 134 patients (mean age 50 ± 13.3 years) and 77% were female. The majority were of African ethnicity (96%). Mitral regurgitation (39%), followed by mixed MVD (38%) were the dominant lesions. Mitral stenosis was found in 23% of the patients. The main aetiologies were rheumatic heart disease (80%), mitral valve prolapse (11%), myxomatous degeneration (6%) and infective endocarditis (3%). Hypertension (30%) and HIV (12%) were the main co-morbidities. Heart failure was present in 78% of the patients at index hospitalisation. The main complications were pulmonary hypertension (28%) and atrial fibrillation (14%).
Conclusion: The patients with MVD tended to be older African females with co-morbidities who had predominant rheumatic mitral regurgitation.

Objectives: The ValveClamp system (Hanyu Medical Technology) is a novel transcatheter edge-to-edge repair (TEER) system designed for ease of operation; however, there is a lack of data on its application in secondary mitral regurgitation (SMR). The authors report the mid-term outcomes of TEER using the ValveClamp system in SMR.
Methods: The study prospectively analyzed consecutive severe SMR patients who underwent transapical ValveClamp implantation at 10 Chinese centers.

Unlabelled: Mitral annular calcification (MAC) is a chronic degenerative process involving the fibrous support structure of the mitral valve. The prevalence of this condition significantly increases with age, and is higher in patients with cardiovascular risk factors or end-stage renal disease. However, patients with systemic lupus erythematosus (SLE) may develop atherosclerosis and MAC at a relatively young age.

Aims: Ischaemic mitral regurgitation (MR) is a dynamic condition influenced by global and regional left ventricular remodelling as well as mitral valvular deformation. Exercise testing plays a substantial role in assessing the haemodynamic relevance of MR and is recommended by current guidelines. We aimed to assess the prevalence, haemodynamic consequences, and prognostic impact of dynamic MR using isometric handgrip exercise.

Atrial fibrillation (AF) is characterized by rapid and irregular contraction of the left atrium (LA). Impacting LA haemodynamics, this increases the risk of thrombi development and stroke. Flow conditions preceding stroke in these patients are not well defined, partly due the limited resolution of 4D flow magnetic resonance imaging (MRI).

Rheumatic heart disease remains common in developing countries. Current guidelines recommend percutaneous mitral commissurotomy (PTMC) as the preferred treatment for patients with rheumatic mitral stenosis (MS). This study reports the clinical outcomes of PTMC for rheumatic MS in contemporary Chinese patients and analyzes prognostic factors.
