The SA Heart Annual Congress will take place from 8–10 November at the Sandton Convention Centre, Johannesburg. The three-day Congress, themed ‘Cardiology Connections,’ will promote collaboration and dialogue among local and international Cardiology professionals. The congress offers a unique platform for experts, practitioners, and researchers worldwide to share insights on the latest advancements and challenges in cardiovascular medicine.

The dynamic programme includes keynote speeches, panel discussions, workshops, and networking sessions. The agenda covers a comprehensive range of cardiology topics, designed to provide practical knowledge and inspire innovation in the field. Attendees will gain critical insights into the latest developments that have the potential to enhance patient care.

“We are excited to welcome a distinguished international and local faculty,” says Dr Ahmed Vachiat, SA Heart Congress Convenor. “At the core of SA Heart is the mission to advance cardiovascular care through education, research, and advocacy. By connecting healthcare professionals from across sectors, this Congress will drive forward our vision of improving cardiovascular care for all in South Africa. We are also grateful for the invaluable support of our local experts, whose contributions consistently uphold international standards of excellence.”

A significant focus this year is strengthening connections among various special interest groups, including the Society of Cardiovascular Interventions (SASCI), Cardiovascular Imaging Society of South Africa (CISSA), Cardiovascular Arrhythmia Society of South Africa (CASSA), Heart Failure Association of South Africa (HEFFSA), Intervention Society of Cardiovascular Allied Professionals (ISCAP), South African Society of Cardiovascular Research (SASCAR), and the Paediatric Society of Cardiology (PCSSA).

Joint sessions and interdisciplinary programmes will enable these groups to work together to enhance healthcare delivery for all patients in need of cardiac intervention and treatment. Workshops and scientific sessions will feature innovative learning approaches aimed at facilitating knowledge exchange and professional growth.

A cardiovascular team from the Mayo Clinic – Prof Vuyi Nkomo (Imaging Cardiologist), Prof Sorin Pislaru (Chair, Structural Heart Disease), and Dr Juan Crestanello (Chair, Cardiothoracic Surgery) – will conduct an echocardiography workshop and contribute to various specialist workshops on Friday morning, November 8th.

Dr Thomas Alexander, a respected interventional cardiologist based in India, will share insights on establishing STEMI networks in South Africa. Prof Stylianos Pyxaras from Germany and Dr Andrew Ludwiniec from the UK will discuss chronic total occlusions and complex coronary interventions. Prof Azfar Zaman and Prof Roy Gardner also from the UK and leaders in their field, as well as Prof Thierry Lefevre from France, will join esteemed local experts in addressing important cardiovascular topics.

A new addition to this year’s programme is the Imbizo on Rheumatology and Cardiac diseases. Over 40 Abstracts have been submitted and research sessions guided by SASCAR will be keeping delegates up to date with the latest in the field of Cardiology.

In addition, an excellent parallel paediatric programme will feature global leaders, Prof Krishna Kumar, from India and Prof McDaniel from the USA, with a pre-congress workshop and highly interactive sessions that will incorporate insights from local experts.

“This year, a Heartbeat Stage will feature insightful talks, engaging presentations, and a special networking address,” says Dr Vachiat. “We are honoured to have Dr Imtiaz Sooliman from Gift of the Givers, who will share his thoughts on ‘Connecting Hearts and Social Responsibility’.”

Surgeons Find Microplastics in Heart Tissue During Surgery

Microplastics seem ubiquitous in today’s environment, being found everywhere from rivers to inside the stomach. Now, in a pilot study of patients who underwent heart surgery, researchers in ACS’ Environmental Science & Technology report that they have found microplastics in many heart tissues. They also report evidence suggesting that microplastics were unexpectedly introduced during the procedures.

Microplastics are plastic fragments less than 5mm wide, or about the size of a pencil eraser. Research has shown that they can enter the human body through the mouth, nose and other body cavities with connections to the outside world. Yet many organs and tissues are fully enclosed inside a person’s body, and scientists lack information on their potential exposure to, and effects from, microplastics. So, Kun Hua, Xiubin Yang and colleagues wanted to investigate whether these particles have entered people’s cardiovascular systems through indirect and direct exposures.

In a pilot experiment, the researchers collected heart tissue samples from 15 people during cardiac surgeries, as well as pre- and post-operation blood specimens from half of the participants. Then the team analysed the samples with laser direct infrared imaging and identified 20 to 500 micrometre-wide particles made from eight types of plastic, including polyethylene terephthalate, polyvinyl chloride and poly(methyl methacrylate). This technique detected tens to thousands of individual microplastic pieces in most tissue samples, though the amounts and materials varied between participants. The blood samples also all contained plastic particles, but after surgery their average size decreased, and the particles came from a wider range of plastics.

Although the study had a small number of participants, the researchers say they have provided preliminary evidence that various microplastics can accumulate and persist in the heart and its innermost tissues. They add that the findings show how invasive medical procedures are an overlooked route of microplastics exposure, providing direct access to the bloodstream and internal tissues. More studies are needed to fully understand the effects of microplastics on a person’s cardiovascular system and their prognosis after heart surgery, the researchers conclude.

Young Boy’s Triumph Over Rare Heart Condition

Hannah Lewis was expecting to learn the sex of her first child at 20 weeks of her pregnancy. Anxious about becoming a mother at just 19, Lewis was thrilled when she learned she was having a boy.

However, with a worried look on her face, her doctor told her that the baby’s organs looked healthy – except for his heart.

The baby was diagnosed with hypoplastic left heart syndrome, or HLHS, a rare condition where the heart’s left side is underdeveloped, doubling the workload for the right side. Days later, doctors at a children’s hospital in Nashville, Tennessee, confirmed the diagnosis.

But Lewis said her faith gave her the strength to believe she was meant to raise this child as a single mother, as well as her own experiences being raised by a single mother herself.

The rest of the pregnancy was filled with checkups and tests but remained uneventful. Then, at 37 weeks, doctors realised he was developing foetal hydrops, a life-threatening condition in which an abnormal amount of fluid accumulates in the tissue around the lungs, heart or abdomen, or under the skin.

Even in shock from induced labour followed by a caesarean, she remembers hearing her son’s first cries:

“They let me see him for just a second,” she said. “I loved him at first sight obviously, but I was super scared because they took him directly to the heart cath lab and for like 12 hours, we didn’t know what was going on. I was very sick so they wouldn’t let me go see him.”

She named him Bennett after learning the moniker means “God’s gift of hope” or “little blessed one”.

“It was so fitting for what he was about to face,” Lewis said.

HLHS is usually treated with either three different surgeries at certain stages of development or a heart transplant.

Because of the complications introduced by foetal hydrops, Bennett Sayles was 6 days old when he underwent his first open-heart surgery. Although the procedure went well, Bennett remained in critical condition on a ventilator. Then, when he was 2 months old, he had a stroke.

After three open-heart surgeries, 9 month old Bennett had stabilised enough to go home. But shortly before he was discharged, he went into cardiac arrest, and was without a heartbeat for six minutes.

“Then, out of nowhere, his heartbeat came back and it was strong,” Lewis said.

Two weeks later, days before his first Christmas, Bennett went home for the first time. After he turned 2, Bennett underwent the second HLHS surgery, which didn’t work and days later, he needed a fifth open-heart surgery.

Some weeks later he went home, but in hours, Bennett was back in the emergency room with staph infection in his chest. However, Bennett made it home again in time for Christmas. And ever since that series of setbacks, things have improved for him.

“His mental capacity is anywhere from 3 to 5 years old, but he’s got this amazing personality,” Lewis said. “He’s just got such a caring heart. When he’s in the room, he really does light it up and he changes the way you see things. I’m inspired every day because of how amazing he is and he doesn’t let anything hold him back or stop him.”

Two years ago, Bennett’s doctors determined that he would never be a candidate for the other surgeries needed to treat HLHS. He could, however, become eligible for a heart transplant.

“It’s debatable whether he’ll get there, but having known Bennett for the last nine years is not surprising at all that he has progressed to this point,” said Dr. Gerald Johnson, the boy’s paediatric cardiologist. “One of the beauties of working with kids is that they fight and they work to get better, and they work through things in ways that we as adults don’t necessarily do. Bennett’s been a particular fighter on that score and his mother is very proactive and in tune with his needs.”

Raising Bennett has taught Lewis and her family to focus on the present. “We don’t know what’s in store for Bennett,” Lewis said. “He could live his whole life like this or we can have him just a few more years. We love every minute we get to have with him.”
