Opening remarks

• Elvis Ndansi recalled the previous session on pain management during labour and delivery and noted the range of Cameroonian specialists in the network, from neurosurgeons to cardiovascular surgeons.
• Dr. Bryan Tegomoh welcomed participants to the 30th edition and said sustainable surgery in Africa needs both infrastructure and technical skills.
• The lead moderator and Louisa Viban were absent on other duties; Dr. Christelle Jouego Tagne co-moderated.
• In his COVID-19 update the Chair said the Delta variant was driving a resurgence, that vaccinated people rarely became very sick but breakthrough infections carried viral loads similar to the unvaccinated, and that mRNA vaccines remained about 88 percent effective against Delta. He cited almost 200 million cases, about 4.4 billion doses given worldwide, and vaccine inequity. Vaccines available in Cameroon included AstraZeneca, Johnson & Johnson, Sputnik and Sinopharm, and Cameroon had received almost a million Johnson & Johnson doses donated by the United States. He urged people at home to take whichever vaccine was available.
• Asked about mask guidance for vaccinated people, the Chair described himself as a mask advocate on empirical grounds: about 20 of some 200 residents at his New York hospital fell ill in the first week of the pandemic, and fewer than five after the hospital mask mandate. Dr. Tegomoh said the virus had humbled everyone, that equal viral loads in vaccinated and unvaccinated Delta infections were unexpected, and that CDC was updating guidance on the evidence available.

Presentation

1. What cardiac surgeons do and how they train

Dr. Pingpoh described cardiac surgeons as people who repair what is damaged in the heart: repairing or replacing valves, bypassing blocked coronary arteries, transplanting hearts and implanting assist devices. In Germany training takes six years, with a set number of cases required before the specialist exam, and most surgeons add a subspecialty such as vascular or thoracic surgery. He stressed that cardiac surgery is distinct from cardiology but depends on it.

2. A cardiac surgical unit is a team

Citing a 2016 EACTS paper, he listed the minimum team: at least one senior cardiac surgeon, a general surgeon, at least two cardiologists, intensive care cover, nurses and perfusionists, supported by vascular and general surgery for complications. Patients need care before, during and after surgery, including a cardiac intensive care unit and diagnostic equipment with staff to run it. Primary care physicians must recognise heart disease early and refer.

3. Rheumatic heart disease is a disease of the poor

Dr. Pingpoh cited about 39 million people living with rheumatic heart disease, over 90 percent in low and middle income countries and mostly under 40, with surgery as the end-line treatment. He noted Cameroon's very young population and a per capita income of roughly 1,500 euros, and the WHO estimate of about 17 million cardiovascular deaths a year, more than 80 percent in low and middle income countries. He said governments tend to treat malaria and typhoid as the priority while cardiovascular disease grows.

4. No African association, little data

He pointed out that Europe, America and Asia have cardiothoracic surgery associations but Africa does not, and that these associations had planned, before COVID-19, to place senior surgeons in African centres. Most published data on cardiac surgery in Africa come from visiting humanitarian teams, and over 90 percent of their patients are paediatric or rheumatic cases.

5. Three models seen in Africa

He described the Ghana model, where Prof. Frimpong-Boateng lobbied from 1981, laid the first brick in 1989 and largely financed the centre through personal effort with partial government integration, and contrasted it with Kenya, where government integrated the programme and paid a senior surgeon to build it. Medical tourism to India or South Africa serves only those who can pay and drains local units of cases. Humanitarian missions by expatriates are not integrated into the health system and take 10 to 15 years to produce an independent team.

6. The Shisong experience

The Cardiac Centre at Shisong had a resident cardiac surgeon, two cardiologists, a cardiac anaesthesiologist and an ICU that he found newer than his own centre's at the time of his visit. Its limits were that it was privately run by the Tertiary Sisters, not fully integrated in the health system, hard to reach, and costly; the moderator's summary put an average operation at about 4,500 euros. He also noted a 2012 Belgian mission at Douala General Hospital that operated on about 45 patients.

7. What sustainability requires

Dr. Pingpoh listed finance (government, NGO or private), integration into a functioning health system with trained referring physicians, an insurance scheme to make surgery affordable (citing Rwanda's national insurance), enough annual case volume to keep teams safe, and above all political will. He said small steps matter and that informing professionals, as the Town Hall was doing, was a start.

Discussion and Q&A

• Should Cameroon aim to be another Rwanda or build its own system from the bottom up? (Elvis Ndansi) Dr. Pingpoh said Cameroon does not lack cardiac surgeons, cardiologists or anaesthesiologists, many abroad and willing to help; nurses, scrub nurses and perfusionists exist in Cameroonian hospitals. What is missing is political will.
• Can the private sector solve this without waiting for government? (Elvis Ndansi to a US gastroenterologist) The gastroenterologist said mission hospitals do a great deal, citing a US NIH R01 grant of about 5 million dollars through the Baptist mission for hepatitis B research, but government policy (for example import taxes on donated equipment) can block private efforts and the poor still need public coverage.
• With 94 percent of health spending out of pocket, should cardiac surgery be covered by social insurance? (Elvis Ndansi) Dr. Pingpoh said it should be part of an insurance scheme, which international partners could support, but that government should invest first in prevention through trained and motivated staff, including in rural areas.
• Do we have the surveillance data on rheumatic heart disease needed to convince decision makers? (Dr. Tegomoh) Dr. Pingpoh called Cameroon a 'black hole' for cardiovascular data: many patients die at home undiagnosed and diagnostic equipment is lacking. He noted Germany's first open heart operation was in 1958 and Ghana's in 1964, yet the gap is now wide because government only acted decades later.
• If specialists opened a private cardiac centre in Cameroon, what would be the main obstacle? (Elvis Ndansi) An interventional cardiologist said fewer than 1 percent of Cameroonians ever get an echocardiogram, so a centre needs a diagnostic and referral pipeline down to district level to reach safe volumes. A second cardiologist stressed the wider team and infrastructure around the surgeon. Dr. Pingpoh added that units should be tied to university medical faculties so students learn the field.
• How do we retain those we train? (Chair) The Chair recalled that in 2008 the government sent nurses, anaesthetists and young surgeons to France and Belgium and, to his knowledge, about 80 percent did not return. Dr. Pingpoh described a German approach in which a returning professional's salary is covered for two to five years, and suggested Cameroon pair training abroad with such guarantees.
• Why do specialists who return clash with the system, and what about people who claim specialist titles after short courses? (a doctor in Tokyo and the Chair) Dr. Pingpoh said doctors are service providers and must return with humility, and that competition for a single top spot holds back collaboration. On credentials he said no one becomes a cardiac surgeon in weeks or two years, and that boards with documented case logs are needed. Elvis Ndansi called on the National Order of Physicians to verify foreign qualifications and suggested anonymous whistleblowing channels.
• Comment from a cardiac rehabilitation specialist in Bamenda He described failing to convince the Shisong management to set up a cardiac rehabilitation unit. Dr. Pingpoh said rehabilitation is an integral, mandatory part of cardiac surgery in Germany.

Calls to action and closing

• Elvis Ndansi summarised the session: infrastructure, trained staff and equipment; rheumatic heart disease in a young population; the three models; the cost at Shisong against incomes in Cameroon; the need for insurance, diagnosis and referral, retention incentives and political will.
• The moderator noted that the Minister of Public Health was expected to speak at a future Town Hall, with a date still being arranged.
• The Chair, a classmate of Dr. Pingpoh, thanked him and proposed that the Town Hall work with him towards a cardiac surgery mission to Cameroon once the crises at home ease. He invited the US gastroenterologist to give a future talk.
• Dr. Pingpoh said the discussion should move from talk to practical action soon.

Next meeting

In a fortnight (expected August 14, 2021); topic not announced.
