PDA endarterectomy through 1cm arteriotomy w "Mills instruments" in spec time. Great job, Dr. Amir Sarkeshik! Mentoring the next gen on complex open maneuvers is more critical than ever. Mastering these skills is what keeps our field safe. #CTO @M_Pompeu_Sa_MD @georgetolisjr

Preop angiogram... obstructed PDA seen filling via L to R collaterals.

TAVR implanted 7 years ago, now w CHF, sev AS/AI. I've had repeated success finding plane btwn native valve cusps & TAVR skirt, working w elevator instrument in R hand and gentle traction grasping top of frame w L hand to "pop" valve out. @M_Pompeu_Sa_MD @tomcnguyen #TAVR

Rheumatic mitral valve disease persists in the US. In this case, severe MR/mild MS and severe TR. This 49 year old tolerated Coumadin without complications for six years, making mitral replacement with a mechanical heart valve an easy choice.

#inspiris implanted 6 years ago. There is very little clinical data to suggest this valve will be as durable as it's predecessor, Magna or MagnaEase. But certainly more expensive. @tomcnguyen @DrZeigler1 @Abedeanda @APolancoMD

Incredible information gained with modern transesophageal imaging! In this case, a previously repaired valve with long-standing residual regurgitation. Hint hint, the mitral valve doesn't quite look like that.

Redo SAVR via aortic root can be tight. I started by freeing the valve sharply under the RCA, transected the prosthesis, repeated the release/transection until it came apart into 3 pieces, removing each segment carefully to protect the annulus. Simple, practical, worked well.

50 y.o woman treated for “HTN & chronic headaches” for decades. Thought weak legs after walking was normal. Finally got a CT chest; revealed the real problem. Simple surgical fix: 24Fr Ao‑to‑Ao bypass. She feels like a new person. Reminder to keep differential wide.

72 yo w h/o bicuspid AS S/P TAVR 5yrs ago, now severe stenosis of implant. Explant revealed massive calcification & dense pannus. Hard to imagine Tavr in Tavr. Standard root enlargement enabled safe implantation of a 29 mm Epic. @DrZeigler1 @JCoselli_MD @Abedeanda @tomcnguyen

Not all aortic valves come out clean. This one was heavily calcified... had to be cut out in several pieces. Mean gradient 74mmHg. Conduction system intact, annulus fully debrided, and a 29 mm prosthesis seated smoothly in a super athletic man.

80 y/o w infected #TAVR (#Sapien). SAVR + Asc aorta replacement via mini-sternotomy. Sapien removed cleanly, no root injury. A standard elevator tool makes separation of native leaflets & frame relatively easy. TAVR explantation is often simpler than it’s made out to be.

Excising an aortic valve as a single piece is a skill set developed when learning to properly detach leaflets at the annular insertion. No need to "tear & pluck" at leaflets & calcium. Almost no annular debridement required. SAVR, w 29mm Abbott Epic valve via mini sternotomy.

on my 26th birthday, i wrote I Took A Pill in Ibiza…10 years ago. The song became popular several years after i wrote it.

85 yo 👱🏼‍♂️, TAVR 3 years ago, now with endocarditis. Ugly, calcified root with obstructed prosthesis, required SAVR & partial aortic wall endarterectomy. Challenging to say the least. 25 mm tissue valve implanted via mini sternotomy. Clamp time 45 minutes.

I use a surgical elevator to intelligently separate native smashed-up aortic leaflets from outer frame with counter-traction by grabbing the top of frame using a grasping tool. Start with the right, non, then left cusp. In 3-5 minutes, it "pops" out. It's not a "sardine can".

Great day! Cardiac surgery is alive & thriving. 3 cases. 1st case, partial anomalous right pulmonary vein into SVC, patch baffled into LA via fossa septostomy. 2nd, AVR/replacement Ascending aorta. 3rd, TAVR explant for endocarditis requiring surgical AVR. All extubated...
