The tropics are uniquely affected by conditions such as rheumatic heart disease (RHD), endomyocardial fibrosis, tropical cardiomyopathies, and pericardial diseases, often resulting from or complicated by endemic infections like malaria, dengue, tuberculosis, and parasitic diseases. Moreover, Human Immunodeficiency Virus-Associated Cardiac Disease (HIVAC) represents an emerging concern in regions with high HIV prevalence, adding complexity to the interplay between infectious and structural cardiac conditions. Despite the significant morbidity and mortality associated with SHD in these areas, research and clinical focus have often been inadequate, underscoring the need for a comprehensive synthesis of available evidence to guide future efforts. This review aims to provide a detailed examination of SHD in the tropics, with a focus on valvular, myocardial, and pericardial diseases linked to tropical infections and conditions. It highlights the epidemiology, pathophysiology, and clinical presentation of key diseases, including RHD, endocarditis, Chagas disease, and HIVAC, as well as other less commonly recognized tropical cardiomyopathies and pericardial disorders. The review also explores diagnostic challenges, advances in imaging and molecular tools, and the role of public health interventions and policy in addressing these conditions.

Pregnancy increases the cardiovascular system's demand, requiring substantial adaptations such as elevated cardiac output (CO), plasma volume, stroke volume (SV), and heart rate (HR), alongside a reduction in systemic vascular resistance (SVR) and mean arterial pressure. These adaptations, essential to meet the hemodynamic needs of both the mother and fetus, often differ from standard echocardiographic measurements used to evaluate cardiac function, making interpretation challenging. Accurate identification of normal echocardiographic parameters during pregnancy is crucial to establishing a baseline for detecting pathological changes. Deviations from these baselines, when recognized early, can assist in risk stratification and inform clinical management of conditions such as heart failure, arrhythmias, or valvular disease. However, many existing studies rely on cross-sectional designs, limiting their ability to provide comprehensive longitudinal insights. For pregnant women, the lack of standardized echocardiographic reference values represents a critical gap. The physiological changes unique to this population, including increased CO and ventricular dimensions, complicate the interpretation of echocardiographic studies using non-pregnant norms. This shortfall can hinder the identification of subclinical cardiovascular alterations, delaying timely intervention. The development of pregnancy-specific echocardiographic reference values is essential for advancing preventive and personalized care.

Recent studies have identified three primary POTS phenotypes-hyperadrenergic, neuropathic, and hypovolemic-each requiring tailored management strategies.

Pharmacologic therapies are primarily used to manage specific symptoms, though the evidence supporting their efficacy is limited. In hyperadrenergic POTS, excessive norepinephrine production or impaired reuptake leads to sympathetic overactivity, making beta-blockers an effective option. Neuropathic POTS, resulting from impaired vasoconstriction during orthostatic stress, responds to agents that enhance vascular tone, such as pyridostigmine and midodrine.
