Abstract A full-term, female presented on her date of birth with severe pulmonary hypertension (PH) and mitral regurgitation (MR), requiring veno-arterial extracorporeal membrane oxygenation. After the treatment, her PH and MR were resolved with no anatomic abnormality present. We propose a positive feedback loop of PH causing right ventricular dilation and interventricular septal shifts, worsening MR, and elevated left atrial, and potentially pulmonary, pressures.

Cardiac myxomas may have different clinical presentations that may expose the patient to sudden death due to obstruction of the left ventricle inflow. The authors report a case of 34 years old male who was diagnosed with left atrial myxoma that presented as mitral valve obstruction with severe pulmonary hypertension. He underwent emergent sternotomy under cardiopulmonary bypass and the myxoma was successfully removed. The postoperative course was uneventful.

Background: In patients undergoing surgery for mitral valve replacement (MVR) for valvular heart disease, pulmonary artery hypertension (PAH) has been considered a major risk factor. In this prospective study, we have studied the early hemodynamic changes and post-operative outcomes of MVR among patients with mild to severe PAH in Bangladesh perspective. Methods: Total 60 patients who underwent mitral valve replacement for predominantly mitral regurgitation (MR) and mixed lesion with mitral stenosis (MS) having pulmonary arterial hypertension ranging from mild to severe pulmonary artery pressure (PAP) were studied prospectively for immediate postoperative haemodynamic and outcome. The mean age of the patients was 36.23±9.18 years. Total 13 (21.66%) patients had mitral regurgitation and 47 (78.33%) had mixed lesion with mitral stenosis. Patients were divided into two groups based on preoperative pulmonary artery pressures. Group A patients with mild to moderate pulmonary hypertension (PASP 40-59 mm of Hg) and Group B patients with severe pulmonary hypertension (PASPe” 60 mm of Hg). Results: After mitral valve replacement, pulmonary arterial systolic pressure (PASP) decreased significantly in Group A to near normal levels (PASP41.25±7.25). In Group B also the PASP decreased insignificantly (PASP 61.85±9.12) but significant residual PAH remained. Operative mortality was nil (0%) in Group A and 6.7% in Group B. Conclusions: Mitral valve replacement is safe and effective at the presence of PAH as long as the PASP is below or equal to 60 mm of Hg. With PASP >60 mm of Hg, MVR carries a high risk of mortality and the patients continues to have severe PAH in the postoperative period. Cardiovasc j 2021; 14(1): 30-36

Giant Left Atrium

A trans-thoracic echocardiography and chest radiograph of a 26 year old lady diagnosed as rheumatic mitral regurgitation with atrial fibrillation revealed a giant left atrium of 10.9 cm size with symptoms of dyspnoea and palpitation. The patient was treated with left atrial size reduction along with mitral valve replacement surgery and showed an excellent and quick recovery with total disappearance of symptoms and restoration of sinus rhythm only within few days.University Heart Journal Vol. 14, No. 1, Jan 2018; 42-44
