Dilatation mitrale percutanée des rétrécissements mitraux en hypertention pulmonaire importante au cours de la grossesse

Le rétrécissement mitral (RM) rhumatismal est la valvulopathie organique la plus fréquente dans les pays en voie de développement. La grossesse constitue l´une des circonstances de décompensation de cette valvulopathie. Nous rapportons notre expérience dans la dilatation mitrale percutanée des rétrécissements mitraux en hypertension pulmonaire importante au cours de la grossesse. La commissurotomie mitrale percutanée a été réalisée chez deux cent vingt-trois parturientes entre janvier 2009 et d écembre 2015. Quarante trois soit 19% de ces patients avaient une hypertension pulmonaire importante (PAPS > 70 mmHg). Toutes les parturientes de notre série sont porteuses d´un RM très serré symptomatique malgré un traitement médical bien conduit. La CMP a été un succès chez l´ensemble des patientes de l´étude, toutes les patientes se sont améliorées sur le plan clinique. L´insuffisance mitrale a progressé d´un grade chez deux patientes. Une patiente a présenté une tamponnade avec une évolution favorable après ponction péricardique. Aucun avortement n´est survenu après procédure et deux accouchements prématurés ont été rapportés. La prise en charge d´un RM serré durant la grossesse doit être multidisciplinaire et faire intervenir le gynécologue-obstétricien, l´anesthésiste et le cardiologue. La CMP constitue actuellement le traitement de référence du RM au cours de la grossesse

The national moroccan registry of ST-elevation myocardial infarction (MR-MI)

Abstract Background MR-MI is the first national Moroccan ST-elevation myocardial infarction (STEMI) registry. Its objectives are to assess patient management modalities and highlight the clinical and therapeutic characteristics of this pathology in all cardiology centres on a national scale. Methods Adult patients presenting with STEMI within 5 days of symptoms onset were enrolled over a period of 18 weeks from April to August 2018. 57 cardiology centres distributed in 22 cities in Morocco participated in the study, including 5 university hospitals, representing 70% of Moroccan centres managing STEMI patients. A case report form was sent to the investigators in both electronic and paper forms. Sociodemographic, clinical, management, revascularization, and follow-up data were collected. Results A total of 809 patients were recruited. The population was mostly male (74.8%) with an average age of 62.6 ± 11.6 years. The most common risk factors were smoking (38.3%) arterial hypertension (30.7%), and diabetes (28%). 30% of patients were admitted within the first 6 h of symptoms onset and early revascularization was performed on 49.6%. Mortality rate was 5.2% in-hospital and 3.2% at the one-month follow-up. Conclusion MR-MI is the first Moroccan STEMI registry on a national scale. Relevant management delays are much longer than other countries, and less than 50% of the patients that present on time benefit from early revascularization. Efforts remain to be done on the optimal diagnosis and treatment of STEMI

Incidental diagnosis of a large left ventricular pseudoaneurysm

Left ventricular pseudoaneurysm is a rare complication of myocardial infarction and represent a myocardial rupture contained within a pericardial space limited by adhesions. Differentiating it from a left ventricular aneurysm can be a real diagnostic challenge. We report a case of a 50-year-old man admitted for symptoms of left heart failure. Transthoracic echocardiography and cardiac computed tomography scan incidentally showed a large lateral left ventricular pseudoaneurysm measuring 75/50 mm in diameter. Patch closure was carried out under cardiopulmonary bypass. Postoperative follow up was uneventful. This case demonstrates the increasing detection of «incidental» left ventricular pseudoaneurysm with more frequent use of multimodality imaging techniques including cardiac CT scan

Multimodality imaging in assessment of mitral valve tumors: An unusual papillary fibroelastoma?

Mitral valve masses are uncommon. These tumors and tumor-like lesions may have similar morphological and clinical characteristics, but different outcomes. Unlike valvular tumors, caseous calcification of the mitral annulus (CCMA) is a benign degenerative disorder, commonly misdiagnosed, thus differentiating it from other mitral valve masses is important to avoid unnecessary surgery. Multimodality imaging can prove a valuable tool for definitive diagnosis. We present a case of a 72-year-old female patient, with coronary artery disease, referred for angina symptoms. Echocardiography detected a mass in the mitral valve annulus. Cardiac magnetic resonance imaging showed a mobile mass respecting the myocardium suggestion an atypical papillary fibroelastoma and surgery was indicated. However, the definitive diagnosis, after histological examination, was CCMA. The aim of this case report is to illustrate the difficulty in differentiating between mitral valve masses and the repercussion on the subsequent management, emphasizing the pivotal role of multimodality imaging
