Introduction: Coronary heart disease is the main cause of morbidity and mortality worldwide. Right ventricular (RV) infarction is often difficult to diagnose and has a poor prognosis due to rhythmic and hemodynamic complications.
Objective: The study of electrical, ultrasonographic, and coronarographic features of the VD Infarction.
Materials and Methods: Retrospective study of patients hospitalized in the Cardiology Department of the Mohammed VI University Hospital in Marrakech over a period of 24 months for MDI extended to the RV.
Results: 120 patients were hospitalized during this period for MI with extension to the VD. Atypical clinical presentation was noted in 10% of cases. Clinical examination on admission revealed signs of right heart failure in 18% of cases, including 6% complicated by cardiogenic shock. Thrombolysis was performed in 10% of the patients, 67% of them successfully. The ECG found an isolated extension to the V3R leads in 76% of the cases and in association with a V4R overshoot in 45% of the cases, conduction disorders were noted in 28% of the cases, presented essentially by first degree auriculoventricular block. Echocardiography showed impaired LV function in 82% of cases, and longitudinal systolic dysfunction of the LV in 65%. Coronary angiography was performed in 91% of the cases, half of which underwent coronary angioplasty. The combination of both CD and IVA damage was found in 40% of the cases, and damage to the middle DC was the most common in almost half of the cases. The most frequent complications were rhythmic and conductive disorders in 38% of cases, and the evolution was fatal in 8% of cases.
Conclusion: Involvement of the RV during MI is characterized by a very critical initial phase, once overcome, the overall prognosis becomes favorable in the long term.
Vasospastic angina (VA), is characterized by symptoms of coronary angina caused by coronary vasospasm, usually in the absence of atherosclerotic changes. It typically presents with chest pain, which can be accompanied by transient electrocardiographic changes, if visualized during the attack. It can also rarely present with severe manifestations of acute myocardial angina, ventricular tachycardia (VT), ventricular fibrillation or cardiac arrest. We report the case of a 25-year-old male patient, with cannabis smoking habit, admitted for palpitations which had revealed a VT in the electrocardiogram (ECG), and for whom a coronary angiography was realised showing a coronary artery spasm (CAS) with no sign of atherosclerotic occlusion.
Left atrial appendage (LAA) aneurysm or giant LAA is an uncommon condition. It could be discovered incidentally during echocardiography examination or in symptomatic patients presenting with tachycardia or embolic events. The giant LAA is a serious condition with a high embolic risk that can cause respiratory distress and even cardiac arrest in children. A conservative surgical approach based on resection of the LAA is recommended and is mostly safe. We report the case of a four-year-old girl presenting with a symptomatic giant LAA removed successfully. The echo-cardiographer must be aware of its appearance mimicking a pericardial effusion and focus on its possible association with other congenital lesions. There are several therapeutic strategies, all with proven efficacy and safety.
Infective endocarditis involving the right side of the heart occurs rarely and often involves the tricuspid valve. The isolated pulmonary valve infective endocarditis (IPVIE) is a less common condition that occurs in specific population. The double outlet right ventricle (DORV) is an unusual congenital heart disease. The association of DORV and IPVIE darkens the prognosis. We report two cases of the association of DORV and IPVIE. The transthoracic echocardiography (TTE) is the base to the diagnosis. Right sided infective endocarditis in the lack of a guided strategy remains a therapeutic challenge.
Erdheim-Chester disease (ECD) is a rare non-Langerhans histiocytic multisystem disorder due to xanthogranulomatous infiltration of tissues by spumous histiocytes, It typically presents with diffuse bone pain however the cardiac manifestation are common and occur to 75% of the patients. It is frequently asymptomatic and detected incidentally on radiological imaging and it most commonly manifests as pericardium and myocardium infiltration We report the case of a 66-year-old woman patient, admitted for diffuse bone pain, asthenia and a left arm weakness who presented and infiltration of the aorta with a coated aspect, a thickened right atrium and a small pericardial effusion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
