Saint Lucia trains its first locally based interventional cardiologist

A Saint Lucian doctor has qualified as an interventional cardiologist, and if he returns home to practise he will be the only locally based specialist in a field that saves heart patients from invasive surgery. Lestin Celestin accepted his Masters in Interventional Cardiology at a Havana institute this month, after presenting his thesis at the end of an 18-month programme.

As reported by St. Lucia Times, Celestin's qualification matters because Saint Lucia has no public cardiac catheterisation laboratory, the specialised unit where these doctors work. Barbados and Trinidad and Tobago both offer the service through public healthcare. On the island, the procedures are available only at the privately run Tapion Hospital, through a visiting overseas specialist who comes periodically.

Interventional cardiology treats coronary artery disease, including ischaemic heart disease, where the arteries feeding the heart become narrowed or blocked. Left untreated, that can cause heart attacks and, in time, heart failure. The procedures are minimally invasive, restoring blood flow before lasting damage is done, which is precisely why the gap in provision matters so much on an island where heart disease is a leading killer.

Celestin is under no illusion about what it would take to close it. A cath lab, he argues in an interview with the Times, is far cheaper to establish than many other specialisms, because interventional cardiology needs a well-trained team rather than the vast staffing of a cardiac surgery unit. His goal, he says, is higher specialised care at home, especially for ischaemic heart disease, and he believes Saint Lucia can reach it. He adds that he is not against private care, but that more Saint Lucians should be able to access life-saving interventions.

The doctor trained through the long-standing Saint Lucia-Cuba bilateral scholarship programme, completing his medical degree at Cienfuegos Medical Science University in 2019 and residencies at home before a clinical cardiology specialisation, also in Cuba. He enrolled in the interventional Masters in January 2025, funded only by a partial scholarship won on academic merit, and studied through Cuba's economic crisis, marked by fuel shortages and prolonged power cuts. Throughout the programme he worked alongside a Cuban team handling at least five cases a day.

For the island, the story speaks to more than medicine. Skilled Saint Lucians training abroad and weighing whether to return is a quiet test of the economy of Saint Lucia, where healthcare capacity sits alongside tourism and infrastructure as a marker of whether the country can retain its own talent. Celestin says regional offers have begun to arrive through colleagues, but his sights, he admits, remain fixed on home. He plans first to finalise the translation of his qualifications.

Visitors have a stake in the story too. The island's northern hotel belt, where most hotels in St Lucia cluster around Rodney Bay and Gros Islet, is a drive from the private Tapion Hospital in Castries, and travellers with existing heart conditions have long factored medical access into their plans. A home-grown interventional cardiologist, once practising, would widen the safety net for anyone who books holidays to St Lucia in later life or with a cardiac history.

Travel insurance remains the sensible first line of cover, as it is anywhere in the Caribbean, and the timing of a trip can matter for health as much as comfort. Many visitors find the driest months are the best time to visit St Lucia, when heat is less punishing for older travellers and outdoor plans are rarely washed out. Direct flights to St Lucia land at Hewanorra in the south, with a transfer of well over an hour to the main resort areas, another practical point for anyone managing a health condition.

Active travellers should note the practicalities too. Diving in St Lucia is a highlight of the southerly marine parks, but certified divers with cardiac histories are usually asked for medical clearance, so a strengthened cardiac service on the island adds reassurance. The same logic applies to exertion at altitude on Gros Piton, a strenuous climb that guides expect walkers to attempt in reasonable shape.

What happens next is not yet settled. Celestin has not announced where he will practise, and no public cath lab has been funded or committed by government. What is confirmed is that the island has produced a specialist it previously had to import, and that the man who trained to fill the gap wants to fill it in Saint Lucia. For the moment, he is happier, he says, than the day he graduated as a general cardiologist, because the qualification is something he always wanted to reach.
