Mitral Repair

Mitral Repair is a point-of-care reference for cardiac surgery residents learning mitral valve repair, built by a practising cardiac surgeon. Open it beside the operating table, at the TEE screen or before a case to see what the repair is doing and why. AN INTERACTIVE VALVE See the valve as the surgeon sees it through the left atrium, side by side with a long-axis cut through A2–P2. Tap any segment for its anatomy, chordal supply and the structures at risk nearby: circumflex artery, coronary sinus, AV node and aortic valve. Switch between eleven lesions, from P2 flail and Barlow's disease to annular dilation, perforation and ischemic tethering, and watch the jet direction follow the lesion. REPAIR TECHNIQUES, STEP BY STEP Each technique is drawn on the valve one step at a time, with indications, pitfalls and what to check before closing: • Ring annuloplasty, complete ring or posterior band • Triangular and quadrangular resection with sliding plasty • PTFE neochords • Chord transfer • McCarthy's measured repair: posterior height to half of A2, partial fold of the free edge, ring chosen by AP diameter • Edge-to-edge (Alfieri) stitch • Commissural and cleft closure • Leaflet augmentation CARPENTIER CLASSIFICATION Types I, II, IIIa and IIIb with mechanism, etiology, TEE findings, repair strategy and teaching pearls. TOOLS FOR THE OR • NeoChord sizer: length from a reference chord or the annular plane, nearest loop size and number of neochords • Coaptation planner: predicted coaptation from A2, posterior height and ring AP diameter • Ring sizer adjusted for the disease • SAM risk checklist from pre-repair echo measurements • Post-repair TEE check: accept the repair or go back on pump • TEE ↔ surgeon's view map showing which segments each view cuts CASE QUIZZES 39 clinical cases on lesions, techniques, TEE, complications and surgical indications, with explanations linked to the techniques. REFERENCED Every technique, classification, case and tool lists its sources, verified against PubMed, with links to PubMed and the full text. PRIVATE AND OFFLINE No account, no ads, no tracking.
