Persistent left superior vena cava (LSVC) is a rare congenital anomaly. Its prevalence in the general population is 0.1 to 0.5%. LSVC is 5 times rarer when accompanied by an absence of the right superior vena cava (RSVC). We present the case of a 54-year-old man who carries a persistent LSVC without RSVC. Clinically, this patient presented a regular bradycardia at 40 per minute associated with a heart failure syndrome. The electrocardiogram diagnosed a complete atrioventricular block and transthoracic echocardiography showed dilated left heart cavities and a left ventricular ejection fraction of 50%. During the procedure of pacemaker implantation, the probe followed an unusual LSVC-coronary sinus-right atrium path and it was not easy to pass through the tricuspid orifice. We propose a review of the literature on this subject, focusing on the clinical implications of this malformation in cardiac stimulation and in other areas of cardiology.

Uncontrolled hypertension was defined by a systolic BP (SBP) ≥ 140 mm Hg and/or a diastolic BP (DBP) of ≥90 mmHg on either of office BP measures in the clinic.

Introduction: Nutritional therapy in the treatment of high blood pressure and heart failure is a real challenge in terms of compliance of sodium restriction for success of the treatment. The study aims to assess the level of patient compliance with the sodium restriction by salt consumption, prescribed by care providers and the associated factors. Materials and Methods: Total daily salt intake was estimated in a cross-sectional study of 166 hypertensive and heart failure subjects monitored in the cardiology department of the “Centre Hospitalier Universitaire - Hubert Koutoukou Maga” (CNHU-HKM), using two 24-hour recalls combined with a food frequency questionnaire for salt-providing foods. Results: Out of the study, 83.7% of patients had a daily intake above recommendations. Factors associated with the non-compliance of salt restriction were the lack of knowledge of palliative spices and herbs of salty taste (p=0.009) and the consumption of salty snack foods and salty peanuts (p=0.032). Conclusion: Nutritional education and support activities should be carried out to improve the salt reduction compliance for these patients.
