Background: Carcinoid heart disease (CHD) is a rare carcinoid syndrome (CS) manifestation, often linked to liver metastasis releasing vasoactive amines. CHD can also result from ovarian neuroendocrine tumours (NETs), an uncommon association.

Cases Presentations: We reviewed three female patients at our NET centre, averaging 63years of age (59-67years). They all had primary ovarian NETs causing CS and CHD.

Discussion: In all patients, investigations identified a diagnosis of CS and CHD secondary to primary ovarian NETs, evident in Tables 1&2. Table2 showed a shared pattern of dilated right ventricles and severe Pulmonary and Tricuspid valves regurgitations, emphasising the cardiac burden. Treatment encompassed both valves replacements alongside ovarian tumour removal, with receiving preoperative somatostatin analogues.One initially declined cardiac surgery but later accepted. Postoperative results uniformly demonstrated disease remission clinically, biochemically and radiologically, reflecting successful tumour resection and cardiac intervention.

	preoperative	postoperative
Case1	ECHO: EDD 50mm Impaired RV	Awaiting
Case2	MRI: RVEDV 240ml RVEF 63%	Normal RV
Case3	ECHO: RVEDarea 14.8cm2/m2 EDV 36.7ml	RVEF 56+/-6%

Conclusion: Tumour excision and cardiac interventions provide optimistic possibilities for curing CS and CHD linked to primary ovarian NETs. Early diagnosis and multidisciplinary involvement improve clinical outcomes.
